Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a sorting device in an awn removal machine.

[Prior art and its problems] Generally, when raising seedlings for rice transplantation, awns must be removed from the seed rice to be sown in seedling boxes for the purpose of uniform sowing. As this type of awn removal means, there are known methods such as those using disks, rollers, screws, worms, brushes, etc. However, these methods do not have very good awn removal efficiency, so a sorting mechanism is used. Because it is necessary to strictly select the removed paddy and the awned paddy,
There is a problem that the device itself inevitably becomes complicated.

In addition, in order to improve the sorting efficiency,
It has been proposed, as shown in Publication No. 130577, that a vibrating means is brought into contact with the lower surface of the forward side of the inclined sorting belt to apply vibrations to the entire forward side of the sorting belt. When used as a sorting means, there is a risk that awned paddy or awns may be mixed into the means for collecting dehulled paddy or awns, or that dehulled paddy may be mixed into the means for collecting dehulled paddy or awns. The problem remains that it is undesirable as a sorting means in an awn removal machine.

The purpose of the present invention is to provide an extremely simple and efficient sorting device that uses the inclination of the sorting belt, the adhesion of the awns of the material, and the rational vibration imparting effect. It is something to do.

[Means for Solving the Problems] The structure of the present invention that solves the problems of the prior art is that a means for removing awns for the supplied awned paddy is provided in the upper part of the housing, and a means for removing the awns to be supplied is provided below the awning means for conveying the awns. It is tilted in the direction perpendicular to the direction, and dehulled paddy, removed awns, etc. are dropped and supplied to the upper end of the slope on the upper side, and a collection means for dehulled paddy is installed on the lower end of the slope, and awns are attached to the lower side of the conveyance. In a sorting device for an awning machine equipped with a sorting belt that is connected to a collecting means for paddy and awns, a device that intermittently contacts the inclined upper end of the upper side of the conveyance side of the sorting belt to generate vibrations on the forward side of the sorting belt. In addition, a vibration control member is provided along the conveying direction of the sorting belt and pressed against the rear surface of the approximately central portion of the sorting belt, and capable of interrupting and controlling the vibration.

[Example] The embodiments of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a partially cutaway front view, Fig. 2 is a partially cutaway side view of the same as above, Fig. 3 is a perspective view of a part of the receiving conveyor belt, Fig. 4 is a front view of the sorting belt section, and Fig. 5 is a partially cutaway side view. It is a partially notched side view same as the above.

Reference numeral 1 denotes a housing, and a hopper 3 is formed in the upper part of the housing 1 and has a droplet 2 for dropping paddy with awns formed on one side. A feed roll 4 for paddy awns having a spline shaft structure is horizontally mounted on the awned paddy drop opening 2, so that the paddy awns are uniformly dropped and supplied. Further, the upper side of the conveyance belt 5, which is horizontally suspended in the housing 1, faces the lower side of the feed roll 4. On the receiving and conveying belt 5, a forcibly conveying belt 6 for paddy with awns, which is shorter than the receiving and conveying belt 5 and has the same conveying direction as the conveying direction of the conveying belt 5, is provided in an overlapping manner.

The receiving and conveying belt 5 and the forced conveying belt 6 are made of a material with moderate elasticity and a rough surface, such as sponge, which has great flexibility, that is, can hold the removed awns. The conveyance speeds of both the belts 5 and 6 are made different so that rolling motion is imparted to the chaffed paddy that is conveyed in a sliding manner between the belts 5 and 6. That is, as shown in FIG. 2, a large-diameter gear 9 is provided at the end of the shaft 8 of one of the belt rolls 7 that rotationally drives the receiving conveyance belt 5, and also rotates the forced conveyance belt 6. A small-diameter gear 12 that meshes with the large-diameter gear 9 is meshed with the shaft 11 end of one of the belt rolls 10. With this configuration, as shown in FIG. 1, the belt roll 10 of the forced conveyance belt 6 is given clockwise rotation, and the belt roll 7 of the receiving conveyance belt 5 is given counterclockwise rotation. At the same time, the forced conveyance belt 6
A high-speed conveying force is applied to the receiving conveyor belt 5, and a low-speed conveying force is applied to the receiving conveyor belt 5, causing a difference in conveying speed at the sliding contact portion of both belts 5 and 6, and the paddy being conveyed through this area is forced to undergo rolling motion. It was designed so that it could be given to

Further, the belt roll 1 of the forced conveyance belt 6
The end of the shaft 11 of the housing 1 is connected to the motor 13 installed in the housing 1 via an interlocking mechanism 14. In the figure, reference numeral 15 denotes a belt guide provided on substantially the entire lower surface of the receiving and conveying belt 5 on its forward path.

FIG. 3 shows another example of the receiving and conveying belt 5, in which a large number of grooves 5a are formed on the surface of the receiving and conveying belt 5 along the conveying direction. Then, the long diameter direction of the awned rice supplied from the feed roll 4 is forcibly aligned along the axial direction of the groove 5a as shown in the figure, and by the sliding conveyance action with the forced conveyance belt 6, The rice grains with awns are rotated around the center of the shorter axis, so that the awns can be removed efficiently.

Next, an embodiment of the sorting device will be described.

Below the conveyance side of the receiving conveyance belt 5,
As is clear from FIGS. 1 and 2, a hopper 16 is provided to feed the sorting section to collect and guide the hulled paddy. 17 is below the housing 1, that is, the receiving conveyance belt 5 and the forced conveyance belt 6.
A sorting belt 17 is placed below the awn removal means consisting of a sorting belt having one side inclined downward in a direction perpendicular to the conveyance direction and made of a material having moderate elasticity and a rough surface, such as a sponge material. The drop port 18 of the supply hopper 16 faces the inclined upper end on the upper side of the conveyor, and the lower part of the lower side of the conveyor of the sorting belt 17 faces outward from the collection port 19 provided on the side wall of the housing 1. The front end edge of the guiding and collecting plate 20 for paddy with awns and awns that protrudes from the front edge faces closely.

In addition, as shown in FIG. 2, the front end sorting belt 1
Approximately the entire length of the lower end edge on the outgoing side of the 7 is exposed to the upper end edge of the guide recovery plate 21 for dehulling, which is inclined at substantially the same angle as the inclination angle of the sorting belt 17. The inclined lower end of the housing 1 is configured to communicate with the lower edge of the collection port 22 provided on the front wall of the housing 1, so that the dehulled rice can be collected without leaking.

Incidentally, the inclination angle of the sorting belt 17 is adjustable, and when the dehulled paddy is collected from the collection port 19 together with awns and paddy with awns, the inclination angle is adjusted to a large extent. When paddy with awns and awns flow out and are collected in the direction of the collection port 22 together with dehulled paddy, the angle of inclination is adjusted to be small. Further, a pulley 26 is provided at the end of the shaft 24 of the belt roll 23 of the sorting belt 17 via a free joint 25, and this pulley 26 and a pulley 26 provided at the end of the shaft 8 of the belt roll 7 of the receiving conveyance belt 5 27 and the belt 28
The drive of the motor 13 is transmitted to the belt roll 23 via the shaft 24.

On the other hand, as shown in FIGS. 4 and 5, a star that intermittently contacts the inclined upper edge of the upper side of the conveyance side of the sorting belt 17, gives vibration to the forward side of the sorting belt 17, and promotes the flow of the dehulled paddy. A vibrating piece 29 with a shaped structure is provided,
To improve sorting efficiency. 30 in the diagram
is a vibration control member which is placed along the transport direction of the sorting belt 17 and is pressed against the back surface of the central part of the lower surface of the forward side of the sorting belt 17, and performs interruption control so that the vibration of the belt caused by the vibrating top 29 does not reach the lower side. , 31 are support members for the vibration control member 30. Although not particularly shown, the vibrating piece 29 is connected to the drive system of the motor 13 so that the vibration can be transmitted as appropriate.

[Effects of the Invention] As described above, according to the configuration of the present invention, the following effects can be obtained.

(a) Of the paddy that has been de-awned, the de-awned paddy rolls down on the sorting belt in a parabolic manner,
Combined with the conveying force of the sorting belt, they are collected toward the lower end of the sorting belt, and paddy with awns and awns are conveyed to the lower side of the conveyor while being engaged and held by the rough surface of the sorting belt. The paddy is collected by a collecting member connected to the downstream side of the conveyance, and it is possible to efficiently sort the paddy with awns and the paddy with awns by a simple and rational means.

(b) In particular, in the present invention, a vibrating means is provided which intermittently contacts the inclined upper end of the upper side of the conveyance side of the sorting belt and vibrates the forward side of the contact belt. It is possible to distinguish between paddy awns and paddy with awns, and the movement relative to the awns at the initial stage of feeding. Furthermore, along the conveyance direction of the sorting belt and on the back surface of the approximately central part of the sorting belt,
Since the vibration control member that interrupts and controls the vibration is pressed into contact with the vibration control member, vibrations are not transmitted to the upper sorting belt section bordering on this vibration control member, and vibrations are not transmitted to the lower sorting belt section, so that the vibration section De-hulled paddy that tries to stay on the slope is efficiently rolled down toward the lower end of the slope, improving collection efficiency, and even if paddy with awns and awns flow down toward the lower end of the slope, the sorting belt does not cause vibrations. It is effectively captured in the lower half of the slope, and the removed paddy, the awned paddy, and the awn can be reliably separated and collected.
