Abstract
The utility model relates to a machine for returning straws to field, comprising a frame, a gear box, a severing rotary cutter, a breaking rotary cutter, a stubble cleaning rotary cutter, an upper feeding pressing wheel, a lower feeding wheel, a lower feeding pressing wheel and a straw secondary breaking device arranged on the back end of the frame. The gear box can be connected with the output shaft of a power machine of a tractor; the severing rotary cutter, the breaking rotary cutter, the stubble cleaning rotary cutter, the upper feeding pressing wheel, the lower feeding wheel and the lower pressing wheel are driven by the gear box; the straw secondary breaking device comprises a secondary breaking stationary knife fixedly arranged on the frame and a secondary breaking rotary cutter driven by the severing rotary cutter through a transmission mechanism. By carrying out the secondary breaking to the straws in segments, the breaking rate can be greatly improved and the operation quality can be greatly improved. The machine for returning straws to field has the advantages of good operation quality and fine straw breaking; a land wheel and a feeler wheel replace an original positioning adjustable slider, change sliding friction to be rolling friction, reduce mechanical operation resistance, reduce operation load, is suitable for different grounds, stable and reliable and reduce the upper feeding wheel and machine damage.
Description
(1) technical field
The utility model belongs to agricultural machinery, particularly a kind of straw cutting apparatus.
(2) background technology
Patent of invention number has been introduced a kind of corn stalk cutting stubble-cleaning field-returning machine for the patent of 200610059338.X, shortcoming is, shred not thorough, there is a spot of stalk not reach broken requirement, below the location adjustable plate when machine advances and ground carry out sliding friction, increased the machine burden, reduced the operating efficiency of machine, go up and feed wheel too much, increased machine loss.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, provide that a kind of operation quality is good, stalk broken tiny, be suitable for Different Ground, steady straw cutting apparatus reliably.
The utility model is achieved by the following technical solution:
Straw cutting apparatus of the present utility model, comprise frame, the gearbox that can link to each other with the power machine output shaft of tractor, the cut-out rotor that drives by gearbox, cut disconnected rotor, stubble-cleaning rotor, go up feed squeeze wheel, down feed wheel, feed and squeeze wheel down, its special character is: frame rear end is provided with stalk second-time breakage mechanism, and it comprises the second-time breakage stationary knife that is fixed on the frame, by cutting off the second-time breakage rotor that rotor drives by transmission mechanism.Stalk to the chopping of section shape carries out second-time breakage like this, improves the percentage of damage of stalk greatly, improves operation quality greatly.
Straw cutting apparatus of the present utility model, for preventing that work tool from obviously sinking and operation walking load is big, the frame bottom is positioned at stubble-cleaning rotor front and is provided with the profiling land wheel.This takes turns the low rolling of form height everywhere, controls the stubble-cleaning degree of depth basically identical of its back, has solved the problem that the rugged plot stubble-cleaning degree of depth is inconsistent, working load is suddenly big or suddenly small, has improved the practicality of this machine.
Straw cutting apparatus of the present utility model, the back lower place of frame are provided with the adjustable adjustment land wheel of height, and it is connected on the location screw that is fixed on the frame by depth location screw mandrel, reaches adjustable effect up and down.Be rolling friction between land wheel and the ground, reduced the mechanical work resistance, reduced working load; Land wheel energy and contour wheel are regulated the stubble-cleaning degree of depth together, can guarantee that this stubble-cleaning degree of depth remains unanimity, makes steadily operation of machine after adjusting finishes.
Straw cutting apparatus of the present utility model, for simple in structure, easy to use, second-time breakage rotor and the transmission mechanism that cuts off between the rotor are belt wheel set or chain wheel pair.
The beneficial effects of the utility model are that operation quality is good, stalk is broken tiny; Land wheel and contour wheel have substituted original location adjustable skid, and changing sliding friction is rolling friction, reduce the mechanical work resistance, reduce working load, are suitable for Different Ground, and be steadily reliable; Reduced to go up and fed wheel, reduced machine loss.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1 power transmission shaft, 2 maize straws, 3 gearboxes, 4 gears, 5 location screws, 6 cut off rotor, feed to squeeze wheel for 7 times, feed on 8 and squeeze wheel, 9 cut disconnected rotor, 10 second-time breakage rotors, 11 second-time breakage stationary knifes, 12 draw the stalk protective cover in, 14 profiling land wheels, 15 depths location screw mandrel, 16 adjust land wheel, 17 hitch frames, 18 stubble-cleaning rotors, 19 times hello wheels.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Straw cutting apparatus of the present utility model, comprise frame, the gearbox 3 that can link to each other with the power machine output shaft of tractor, the cut-out rotor 6 that drives by gearbox, cut disconnected rotor 9, stubble-cleaning rotor 18, go up feed squeeze wheel 8, down feed wheel 19, feed and squeeze wheel 7 down, frame rear end is provided with stalk second-time breakage mechanism, and it comprises the second-time breakage stationary knife 11 that is fixed on the frame, by cutting off the second-time breakage rotor 10 that rotor drives by belt wheel set or chain wheel pair.The frame bottom is positioned at stubble-cleaning rotor front and is provided with profiling land wheel 14.The back lower place of frame is provided with the adjustable adjustment land wheel 16 of height, and it is connected on the location screw 5 that is fixed on the frame by depth location screw mandrel 15.
Straw cutting apparatus of the present utility model, gearbox 3 connects engine by power transmission shaft 1, the output shaft of gearbox drives by gear pair and cuts off rotor 15, feed the in-line gears that squeeze wheel 7 down and drive to feed down and squeeze wheel thereby the in-line gears of the in-line gears that cut off rotor by gear 4 drive, feed down and squeeze wheel and drive to go up to feed by gear pair and squeeze wheel 8.Following feeding squeezed wheel 7 again by feeding wheel 19 under the chain wheel pair drive.Cut off rotor 15 by the moving rotor 9 that breaks of cutting of belt pulley subband.Each is fed wheel and is a shape and has hello the gear teeth.Mesh by guide gear between the in-line gears of gear 4 and stubble-cleaning rotor 18.Also be provided with the stubble-cleaning dust cap on the frame and cut off protective cover.Frame is connected with the frame of tractor by hitch frame 17.Be provided with between the top of cutting disconnected rotor and feeding wheel down and the hitch frame below and draw stalk protective cover 12 in, prevent to cut disconnected whole straw and upwards disorderly go here and there.
Straw cutting apparatus of the present utility model, when locomotive shunting, at first upright maize straw 2 is pushed over, stalk is cut straw disconnected at position, the face of land through cutting disconnected rotor 9, and stalk flowed to down obliquely upward feed to squeeze wheel and go up to feed and squeeze wheel (draw the stalk protection in and build auxiliary effect of drawing stalk in), straw is being fed up and down under the acting in conjunction of crowded wheel, the straw that straw is flowed to high speed rotating cuts off rotor, cutting off under rotor and the acting in conjunction of cut-out stationary knife (being positioned on the frame) the stalks cutting section of one-tenth shape, last under the effect of protective cover, the stalk after the chopping is shed to second-time breakage rotor 10 and second-time breakage stationary knife 11 and is carried out second-time breakage.Simultaneously under the operation of stubble-cleaning rotor, finish the stubble-cleaning soil moisture conservation operation of loosening the soil.
