As shown in Fig. 3～Fig. 7, thrashing cylinder 16 includes: the rake of the circular cone shape (more leaning on an example of the shape that end is the thinnest) being equipped in its leading section holds together portion 41 and is connected to the threshing process portion 42 that this rake holds together the rear end in portion 41, on the outer peripheral face that rake holds together portion 41, it is equipped with integratedly, when thrashing cylinder 16 spinning movement, the straw that extracts supplied from supply mouth 25 is held together 2 helical tooths 43 of conveying towards rearward threshing process portion 42 rake.
Threshing process portion 42 includes: the 1st support plate 44, is integrally equipped in the front portion of fulcrum 15；2nd support plate 45, is integrally equipped in central part before and after fulcrum 15；3rd support plate 46, is integrally equipped in the rearward end of fulcrum 15；6 i.e. pipe parts of threshing tub 47 (example of bar-like member) 47, with before and after fulcrum 15 towards posture, when arranging along the circumferentially spaced certain intervals (example of predetermined distance) of thrashing cylinder 16 by these support plates 45～46 support；Multiple threshing tooths 48, are equipped in each threshing tub 47, to separate the state that certain intervals (example of predetermined distance) arranges in the longitudinal direction, from protruding outside to thrashing cylinder 16 of threshing tub 47；Deng.
According to this structure, thrashing cylinder 16 has the space S being communicated to threshing chamber 14 in the inside in threshing process portion 42, threshing processed material is allowed to enter in this internal space S, thus, when its spinning movement, while threshing processed material about and the threshing processed material entered in internal space S being stirred, these threshing processed materials being implemented threshing and processes, it is to be realized by the impact carried out by threshing tub 47 and threshing tooth 48 etc. that described threshing processes.
I.e., even if extracting in the case of straw is supplied in threshing chamber 14 as threshing processed material using substantial amounts of, it also is able to the process space that the internal space S of thrashing cylinder 16 processed as threshing and effectively utilizes, it is possible to avoid threshing processed material in the process space be detained or process space saturated, can prevent to result from being detained or processing the saturated of space of threshing processed material, threshing processed material does not carries out sufficient threshing and processes the problem just leaked down from notch board 17, and threshing process needed for load increase thus relative to thrashing cylinder 16 transmission drive system damage problem etc..
In addition, when the spinning movement of thrashing cylinder 16, the most multiple threshing tooths 48, even form 6 threshing tub 47 in the i.e. threshing process portion 42 of barrel of thrashing cylinder 16, all work, it is possible to realize the raising of threshing performance and threshing efficiency as the threshing processing component acting on threshing processed material.
And, when the spinning movement of thrashing cylinder 16, with under the effect holding together portion 41 at rake by rake hold together conveying extract straw together with, be successfully flowed into around thrashing cylinder 16 and in internal space S from the supply ambient atmos that sucks of mouth 25 along with the rotation of helical tooth 43, thus, the straw bits being prevented from being produced by threshing process wait and flow out to feeder 13 from supply mouth 25, and can carry out threshing processed material more quickly to threshing process downstream, the direction i.e. conveying at rear.
nullAnd，Inside from the ambient atmos of the supply mouth 25 suction feeder 13 by being connected with supply mouth 25，And this feeder 13 connects with the delivery outlet (not shown) being formed at the recovery terminal region extracting recoverer and supply mouth 25，So when the spinning movement of thrashing cylinder 16，Under sucking action produced by the rotation of helical tooth 43，At dust such as the straw bits processed and produce in recycling by extracting of extracting that recoverer carries out also together with ambient atmos，It is flowed into surrounding and the internal space S of thrashing cylinder 16 via the inner space of feeder 13 and supply mouth 25 from the delivery outlet extracting recoverer，Result，The attachment extracting the straw bits etc. at recoverer can be suppressed to pile up or fly upward，The conveying extracting straw that can suppress to result from this attachment to pile up is bad、And result from this working environment flown upward and the variation etc. in the visual field.
Each support plate 44～46 is the circle centered by fulcrum 15, at its outer circumferential side on the equidistant position of fulcrum 15, when along its circumferentially spaced certain intervals arrange be formed can support link threshing tub 47 6 linking part 44A～46A.
That is, at the outer circumferential side of each support plate 44～46, when along its circumferentially spaced certain intervals arrange equipped with 6 threshing tub 47, the barrel dliameter making thrashing cylinder 16 is relatively big, thereby, it is possible to prevent the winding extracting straw to thrashing cylinder 16.
nullEach threshing tub 47 is formed as a linearity，The 1st web 80 it is equipped with integratedly in its front end，Before and after it, pars intermedia is equipped with the 2nd web 81 integratedly、It is equipped with the 3rd web 82 the most integratedly，1st web the 80 and the 3rd web 82 is formed as，Bolt link can be carried out relative to the linking part 46A of the linking part 44A of the 1st support plate 44 and the 3rd support plate 46，2nd web 81 is formed as，Bolt link can be carried out from front and back both sides relative to the linking part 45A of the 2nd support plate 45，By by the 1st web 80 bolt link on the linking part 44A of the 1st support plate 44，2nd web 81 is engaged from rear and bolt link is on the linking part 45A of the 2nd support plate 45，By the 3rd web 82 bolt link on the linking part 46A of the 3rd support plate 46，Can so that its fore-and-aft direction consistent with direction before and after thrashing cylinder 16 usual posture equipment，In addition，By by the 1st web 80 bolt link on the linking part 46A of the 3rd support plate 46，2nd web 81 is engaged from front and bolt link is on the linking part 45A of the 2nd support plate 45，By the 3rd web 82 bolt link on the linking part 44A of the 1st support plate 44，Can be so that upset posture equipment in opposite direction before and after its fore-and-aft direction and thrashing cylinder 16.
That is, each threshing tub 47 is equipped to, and can change towards and upset posture in opposite direction before and after becoming its fore-and-aft direction usual posture consistent with direction before and after thrashing cylinder 16 and its fore-and-aft direction and thrashing cylinder 16.
In each threshing tub 47, multiple installing hole 47A that threshing tooth is installed, and to wear with following state along its fore-and-aft direction by the state of certain spacing P arrangement, i.e., make distance L1 at the center of installing hole 47A from the front end of threshing tub 47 to foremost and from the rear end of threshing tub 47 to the distance L2 difference half pitch at center of rearmost installing hole 47A.
And, 6 threshing tub 47 are to be linked supporting towards contrary state by each web 80～82 before and after adjacent threshing tub, thus, use identical parts as 6 threshing tub 47, and each threshing tooth 48 of thrashing cylinder 16 is in the state of the half pitch that staggers in the longitudinal direction with the threshing tooth 48 being equipped in adjacent threshing tub 47.
I.e., the helical form that each threshing tooth 48 offsets with being equipped to position half pitch half pitch on whole thrashing cylinder 16, thus, in the spinning movement of thrashing cylinder 16, not only to extracting straw enforcement threshing process, also play and will extract the conveying function that straw is sent to threshing process downstream, direction i.e. rear.
In addition, usual posture and upset posture is become by being equipped to can change towards by each threshing tub 47, because of threshing processed material amount many and easy to wear, in the case of being positioned at the abrasion significantly of the threshing tooth 48 that threshing processes direction upstream side, by change each threshing tub 47 towards, can by the position change of the multiple threshing tooths 48 being had in each threshing tub 47 be quickly, the threshing of threshing tooth 48 and difficult abrasion that threshing easy to wear processes direction upstream side processes the state that the threshing tooth 48 in downstream, direction has exchanged, thus, the threshing tooth 48 in abrasion downstream, less process direction can be processed the threshing tooth 48 of direction upstream side as the threshing that threshing processed material amount is more and effectively utilize.
Each threshing tooth 48 is made up of the pole steel inserted in the installing hole 47A of threshing tub 47, the threshing tooth 48A of the leading section being provided in the toe lateral of thrashing cylinder 16, i.e. threshing process portion 42 in these threshing tooths 48, for having the minor diameter part inserted in corresponding installing hole 47A and the restriction band stepped-style to the large-diameter portion 48b inserted of installing hole 47A, minor diameter part is formed for relative to the fixing outer screw section 48a of threshing tub 47, being removably mounted on the assigned position of corresponding threshing tub 47 with nut 64.
The threshing tooth 48B of the pars intermedia being provided in the pars intermedia of thrashing cylinder 16, i.e. threshing process portion 42 is formed as a linearity, and, to be positioned at the state on the line at the center of center and the threshing tub 47 linking fulcrum 15, on the assigned position of the threshing tub 47 being welded and fixed on correspondence.
It is provided in the rearward end of thrashing cylinder 16, the i.e. threshing tooth 48C of the rearward end in threshing process portion 42, for having the minor diameter part inserted in corresponding installing hole 47A and the restriction band stepped-style to the large-diameter portion 48b inserted of installing hole 47A, minor diameter part is formed for relative to the fixing outer screw section 48a of threshing tub 47, and large-diameter portion 48b is bent to " > " shape, and, when its protuberance has the angle of sweep θ b (with reference to Fig. 7) that the direction of rotation upstream side towards thrashing cylinder 5 tilts, on the assigned position of the threshing tub 47 being removably mounted at correspondence with nut 64.
nullI.e.，It is removable for being positioned at each threshing tooth 48A and each threshing tooth 48C at both ends before and after threshing process portion 42，So as the countermeasure being positioned at when threshing processes threshing tooth 48 (threshing tooths processing direction upstream side by threshing in multiple threshing tooth 48B of the pars intermedia the being positioned at threshing process portion 42) noticeable wear in long-term use of direction upstream side，Can change each threshing tub 47 towards，In the case of the state that the threshing tooth 48 by multiple threshing tooth 48 location change being threshing tooth 48 and the difficult threshing worn and torn process downstream, direction that threshing easy to wear processes direction upstream side has exchanged，As long as by changing to towards change on the position contrary with the origin-location for thrashing cylinder 16 due to each threshing tub 47、Each threshing tooth 48A and each threshing tooth 48C in rear and front end portion changes，Just can make these threshing tooths 48A、48C returns to original position.
In addition, the threshing many in threshing straw quantitative change processes downstream, direction, the threshing tooth 48C of the rearward end being positioned at thrashing cylinder 5 inhibits the hook of threshing straw due to the existence of its angle of sweep θ b, it is possible to suppression results from the delay of threshing straw of this hook, it is possible to promote that this threshing straw (discharging straw) is from the discharge of outlet 23.
As a result, there is the excellent disposal ability of the raising that can realize threshing performance and threshing efficiency, and the most fine in terms of being used for guaranteeing for a long time the maintainability of this excellent disposal ability.
Such as Fig. 3, shown in Fig. 4 and Fig. 8, notch board 17, to arrange equipped with the multiple taeniaes 66 being made up of banding steel plate towards ground before and after the state at the circumferentially spaced certain intervals of thrashing cylinder 16 on pedestal 65, arrange equipped with multiple 1st horizontal stripes 67 being made up of the banding steel plate being bent to arc-shaped towards ground with the state left-right of the spaced up certain intervals in direction of principal axis i.e. front and back at thrashing cylinder 16, between the 1st adjacent horizontal stripe 67, arrange equipped with multiple 2nd horizontal stripes 68 being made up of the piano wire rod being bent to arc-shaped towards ground separating the state left-right of certain intervals in the longitudinal direction, its mesh is formed as the rectangle grown crosswise, longer than along the length on the direction of fore-and-aft direction along the length on the direction of thrashing cylinder 16 circumference.
I.e.; by notch board 17 is configured to; its mesh is the rectangle grown crosswise longer in the direction of rotation of thrashing cylinder 16; by processing the simple grain grain etc. obtained and easily leak down from notch board 17 extracting the threshing that straw carries out; thereby, it is possible to avoid because simple grain grain is from the decortication grain being suppressed and produce that leaks down of notch board 17.
As shown in Figures 3 and 4, in this sheller unit, the power of the change speed gear box outside figure passes to the fulcrum 20A of windmill 20 via the 1st drive mechanism 69 of V belt translation formula, pass to the fulcrum 15 of thrashing cylinder 16 from the power of this fulcrum 20A via the 2nd drive mechanism 70 of V belt translation formula and the 3rd drive mechanism 71 of through-drive formula, and be delivered to feeder 13 via the transmission clutch 72 of the 2nd drive mechanism 70 and band tension type.
Additionally, reference 24 shown in Fig. 3 and Fig. 4 is the top board on the top that can be opened and closed to be equipped in sheller unit, within it on surface, the spinning movement along with thrashing cylinder 16 is had to send dirt valve 49 by the straw that extracts in threshing chamber 14 to the multiple of threshing process downstream, direction guiding with the state fixed equipment arranged with separating certain intervals in the longitudinal direction.And, it is also possible to send dirt valve 49 to be set as regulating the movable of aperture according to the threshing processed material amount in threshing chamber 14 this, realize the raising of threshing performance and threshing efficiency further.
As shown in Fig. 4～Fig. 7, Fig. 9, outside the left and right of thrashing cylinder 16, separating on the position of predetermined distance from the rotational trajectory K of threshing tooth 48, equipped with supporting accept before and after net 17 and top board 24 towards bearing support 50,51, on bearing support (example of fixed component) 51 on the right side of the direction of rotation downstream being provided in thrashing cylinder 16 i.e. thrashing cylinder 16 in these bearing supports 50,51, it is equipped with and multiple cuts stalk cutter 52.
Respectively cut stalk cutter 52, threshing on bearing support 51 processes at downstream, direction to offset the state of 1/4 spacing (=1/4P) relative to corresponding threshing tooth 48 position, in the way of the outside from threshing tooth 48 enters between the rotational trajectory K of corresponding threshing tooth 48, it is provided to ratio row's stalk mouth 18 and processes on the position of direction upstream side by threshing.
According to this structure, straw is extracted under the effect of the spinning movement of thrashing cylinder 16 while being processed while being carried by threshing from what supply mouth 25 was supplied in threshing chamber 14, when being transported to threshing process downstream, direction by this conveying, processed by threshing hereafter, it is transported to the upper side of threshing chamber 14 every time, all it is cut off on stalk cutter 52 cutting by pushing and pressing, carry simultaneously towards row's stalk mouth 18, along with the row's of arrival stalk mouth 18, flow down to outlet 23 from row's stalk mouth 18 with the state of chopping, be discharged into car from outlet 23.
I.e., downstream, direction is processed in threshing, implement threshing to process while straw will be extracted shreds with cutting stalk cutter 52, it is possible to prevent produce because implementing threshing to process when long stalk to extract straw winding on thrashing cylinder 16 and the winding etc. each other of long stalk, it can be avoided that the increase of the conveying load caused because this is wound or wrapped around, and it is no longer necessary to the row's stalk process after harvesting required when being discharged into outside car with the state of long stalk.
And, the threshing more non-threshing straw processes direction upstream side, do not carry out the cut-out cutting stalk cutter 52 to extracting straw, it is possible to avoid not taking off, because of be attached to extract the cutting action that is easily subject on straw to cut stalk cutter 52, the probability that grain is damaged by cutting the cutting action of stalk cutter 52 together with extracting straw, in addition, even if processing direction upstream side grain in threshing and entering between the straw becoming block because of long stalk winding each other etc., it also is able to process the cutting action cutting stalk cutter 52 in downstream, direction by threshing and will go into the grain between the straw of bulk and take out, it can be avoided that be discharged into outside car the generation of the 3rd class loss caused together with block straw because entering into the grain between block straw.
And then, by the threshing cutting stalk cutter 52 row of being provided in stalk mouth 18 is processed direction upstream side, the grain taken out from block straw under the cutting action cutting stalk cutter 52 leaks down towards swing sorting mechanism 19 from accepting net 17, it is possible to avoid the generation of the 3rd class loss caused because the grain taken out from block straw flows down from row's stalk mouth 18.
And then, the special shredding mechanism of chopping process is carried out owing to need not the straw of discharging after threshing is processed by equipment, correspondingly, it is possible to realize the simplification of structure and the reduction of cost, and the lightweight being capable of car body brings, the alleviating of load that united reaper is overall.
As shown in Fig. 4～Fig. 7, Fig. 9, it is the most integral part of by the two side 53A a pair of the steel sheet component 53 being bent to U-shaped for respectively cutting stalk cutter 52, the midfeather 53B of steel sheet component 53 is formed as and the linking part of bearing support 51 bolt link, thus, compared with being individually formed and respectively cutting the situation that stalk cutter 52, respectively bolt link are constituted on bearing support 51, it is possible to realize assembling the raising of workability when cutting stalk cutter 52.
Each sidewall 53A of steel sheet component 53 is formed as, in the assembled state before and after side look up in isosceles triangle, it is upper and lower waits rim portion to become the blade part 52a cutting stalk cutter 52.
I.e., respectively cut stalk cutter 52 to be configured to, on lower two edges, there is blade part 52a thereon, and by spinning upside down change towards changing used blade part 52a, thus, in the case of cause the sharpness of the blade part 52a in using to reduce because of abrasion or defect etc., even if not carrying out cutting grinding or the replacing of stalk cutter 52, also be able to by change cut stalk cutter 52 towards and replace used blade part 52a, tackle simply and at low cost.
As shown in Figure 10, the scalping 31 roughly selected is made up of the sorting plate 54 of steel plate, described sorting plate 54, by going out multiple sorting sheet 54A, make it in the squamous upward tilted in the way of more leaning on its sorting downstream, direction the most by the top, and arrange and be formed as staggered between the sorting sheet 54A in prostatitis of the sorting sheet 54A of rank rear, and be arranged in a staggered on direction all around formation multiple leak down mouthful 54B, this sorting plate 54 with more by the inclination attitude bolt link of its sorting downstream, direction hind wing the most by the top in screen box 29.
I.e., the scalping 31 roughly selected is constituted with sorting plate 54, so with arrange compared with outfit is such as made up of the situation of scalping 31 etc. multiple gillis (チ ヤ Off リ Star プ) that banding steel plate is constituted in the way of separating certain intervals in the longitudinal direction, it is possible to realize the simplification of structure and the reduction of cost.
nullAnd，By by multiple sorting sheet 54A all around on be arranged in a staggered formation，In Screening Treatment，Sorting process thing in scalping 31 is not to be biased against on left and right directions on one side but is uniformly distributed，It is possible to promote grain leaking down from mouthful 54B that respectively leaks down，In addition，Owing to scalping 31 hind wing tilts，So compared with the situation with flat-hand position equipment scalping 31，In Screening Treatment，The power that sorting process thing is released by scalping 31 to the top of sorting process direction upstream side becomes big，Thus，Sorting process thing can be suppressed to the conveying in sorting downstream, direction，And the up and down motion of sorting process thing becomes violent，The difference in specific gravity sorting of sorting process thing can be more effectively carried out，It is possible to reduce the generation of the 3rd class loss that grain is discharged into car from outlet 23，And grain the leaking down from mouthful 54B that respectively leaks down that proportion is bigger can be promoted，Result achieves the raising of grain organic efficiency.
Each sorting sheet 54Aa of the left and right center side being positioned at sorting plate 54 in each sorting sheet 54A is formed as overlooking roughly triangular shape, other each sorting sheet 54Ab being positioned at both ends, left and right are formed shorter than the sorting sheet 54Aa of left and right center side, the rectangle that mouthful 54B that respectively leaks down is formed as identical.
nullI.e.，Mouthful 54B that respectively leaks down is formed as ratio to overlook the sorting sheet 54Aa that roughly triangular shape etc. is gone out、The rectangle that 54Ab is big，Thus，The leaking down from mouthful 54B that respectively leaks down of sorting plate 54 such as grain can be promoted，In addition，By the sorting sheet 54Ab at the both ends, left and right of sorting plate 54 is formed shorter than the sorting sheet 54Aa of left and right center side，Mouthful 54B that leaks down that can promote the both ends, left and right easily piling up sorting process thing from sorting plate 54 such as grain leaks down，Result，The 3rd class loss that grain can be reduced not leak down from mouthful 54B that respectively leaks down of sorting plate 54 and be discharged into car from outlet 23，And it can be avoided that the reduction of the efficiency of separation caused because the sorting process thing at the both ends, left and right of sorting plate 54 piles up，It is possible to realize the efficiency of separation and the raising of grain organic efficiency.
It addition, in this united reaper, owing to as described above the direction of rotation of thrashing cylinder 16 to be set to that when front is observed be dextrorotation, the trend that the quantitative change leaked down in the right side having sorting process thing i.e. to accept net 17 from the direction of rotation downstream of thrashing cylinder 16 is many.
Therefore, in the case of the sorting process thing being configured to make to leak down from undertaking net 17 directly runs down into swing sorting mechanism 19, the sorting process thing being supplied to swing the position, right side of sorting mechanism 19 becomes many, the distribution swinging the sorting process thing on the left and right directions of sorting mechanism 19 becomes uneven, is easily caused reduction and the increase of the 3rd class loss of the efficiency of separation.
nullSo，In this united reaper，As shown in Figure 4，On the right side wall 55 of the sheller unit 5 in the direction of rotation downstream being positioned at thrashing cylinder 16，It is equipped with the sorting process thing leaked down in the right side accepting net 17 from the direction of rotation downstream being positioned at thrashing cylinder 16 to guide and make its guide plate 56 flowed down to the left and right center side swinging sorting mechanism 19，Thus，Major part is fed into the left and right center side swinging sorting mechanism 19 from the sorting process thing that undertaking net 17 leaks down，Along with swinging the swing of sorting mechanism 19 and uniform distribution in the lateral direction，It is possible to make sorting process thing be not to be biased against on one side on the left and right directions swinging sorting mechanism 19 but it is uniformly distributed，Result，It can be avoided that because sorting process thing is biased against the reduction of the efficiency of separation caused and the increase of the 3rd class loss on one side on the left and right directions swinging sorting mechanism 19.
As shown in Figure 1, Figure 2 and shown in Figure 11, in the right-hand end of vehicle body frame 1, it is equipped with the assistance platform 57 used when utilizing the sack-filling device 6 of the right-hand part being loaded in vehicle body frame 1 to carry out packing operation, its with front and back towards fulcrum 58 as fulcrum, may be switched to the work posture that lodges in the way of stretching out towards the right outside of car body and storage posture that the right-hand end along vehicle body frame 1 erects, and by keeping work posture with the abutting of vehicle body frame 1, by figure outside setting tool remain storage posture.
In addition, sack-filling device 6 is equipped with sunshade 63, this sunshade 63 can with before and after the upper end being provided in this grain box 40 towards fulcrum 60 switch to cover the effect posture of the top of the operator stepping on assistance platform 57 enterprising luggage bag operation as fulcrum, storage posture with the top being positioned at sheller unit 5, and, by with on the right side of the upper end being provided in grain box 40 before and after towards the 1st retainer 61 abut and keep work posture, by with on the left of the upper end being provided in grain box 40 before and after towards the 2nd retainer 62 abut keep receive posture.
That is, by sunshade 63 is switched to effect posture, it is possible to carry out the pack operation on assistance platform 57 in the cool, it is possible to improve working environment when carrying out packing operation, the fatigue strength of pack operation is alleviated.
Sunshade 63 includes: the frame section 63A being made up of the pipe steel being bent to U-shaped and the sunshade portion 63B being made up of the interior steel sheet component being connected on this frame section 63A; when moving traveling or to warehouse row and then storage; by switching to storage posture, it is possible to play the function preventing guard block that other objects contact from above sheller unit 5.
[other embodiments]
It is exemplified below other embodiments of the present invention.
