Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a threshing and sorting device configured to sort the threshed material from a handling chamber while being transferred in the direction of the rotational axis of a handling cylinder.

Conventionally, in the above-mentioned apparatus, the threshed material from the handling chamber is dropped onto a swinging sorting plate through an opening formed at the end of the handling chamber in the culm transfer direction, and is sorted while being transferred in the axial direction of the handling cylinder. Although the system is configured to process the material, the material to be processed tends to concentrate in some areas on the sorting board and fall, and the grains mixed into the material to be processed are not sorted and collected and are released to the outside together with straw waste. This caused the problem of reduced grain collection efficiency.

In view of the above-mentioned points, the present invention enables the threshing process to be distributed and supplied onto the swinging sorting plate, thereby improving the grain sorting performance of the swinging sorting plate in accordance with the amount of straw waste generated. The purpose is to improve threshing performance.

Next, embodiments of the present invention will be described in detail based on the drawings.

A handling chamber 2 in which the handling cylinder 1 is mounted on a shaft, and a processing chamber 4 in which the processing cylinder 3 is mounted in a shaft.
are arranged side by side, and the threshing process is carried out from the bottom of both chambers 2 and 4 to the rear, through the cooperation of specific gravity sorting by the swinging sorting plate 5 and wind sorting by wind-selecting air supplied from the winnower 6. A sorting section 7 is provided which performs sorting while being transferred in the direction of the rotational axis of the handling cylinder, and is configured to thresh the husks conveyed by the feed chain 8 and sort and collect the grains. A threshing and sorting device is constructed.

The sorting section 7 includes a first object collection section 9 that collects the first object below the swinging sorting plate 5 that receives the threshed objects falling from both chambers 2 and 4, and a first object collection section 9 behind it. A secondary material collection section 10 is provided for collecting secondary materials such as grains with branches, and 1
The No. 1 item collected in the No. 1 item collection section 9 is transferred to the No. 1 screw 11.
At the same time, the second grain collected in the second grain collecting section 10 is conveyed to one side laterally through the second grain collecting section 10 and collected from the end thereof to the grain collecting section 12 via the grain lifting device 12. The grain is transported laterally through a No. 2 screw 13, and is supplied from its terminal end to the processing chamber 4 through a thrower 14 for re-threshing.

A receiving net 15 is stretched over the lower part of each of the chambers 2 and 4, and openings 16 and 17 are formed at the terminal ends of the chambers 2 and 4 in the direction of shell culm transfer, and from the lower part of the openings 16 and 17 to the rear. A receiver 18 is provided to catch the threshed material falling from the openings 16 and 17 over the course of the threshing process in both chambers 2 and 4. Receiving net 1

On the other hand, the processed materials that have not passed through the receiving net 15 are collected. Receiver 1
It is configured so that it is supplied falling onto the top of the 8.

A rotary body 19 is provided on the receiver 18 so as to be freely driven and rotatable around a horizontal axis Q that is substantially orthogonal to the rotation axis P of the handling barrel. A collision member 20 is provided that bounces the processed material onto the swing sorting plate 5, and the lower part of the receiver 18 is connected to a receiving net 21.
The openings 16 and 1 can be prevented from being mixed into the processed material in the two chambers 2 and 4 and falling through the receiving net 15.
7 and separated due to the agitation action of the rotating body 19, the processed materials with a size smaller than the set amount are collected by falling to the terminal side of the first material collection section 9 through the receiving net 21, and then The material to be processed is distributed and supplied onto the oscillating sorting plate 5 while threshing is auxiliary due to the cooperation of the releasing action of the rotating body 19 and the rebounding action of the collision member 20.

The openings 16 and 17 are formed from positions corresponding to both longitudinal ends of the rotary body 19 over a length of about 113 of the total length thereof, and on the other hand, on the rear end side of the receiver 18. , guides 22 are arranged in parallel so that the rearward side is oriented toward the left and right center. The material is supplied in a diagonal direction to the oscillating sorting plate 5, and is distributed over almost the entire width of the swinging sorting plate 5 in the lateral direction by its rebound.

In the figure, reference numeral 23 denotes a scattering prevention member located above the rotating body 19 and arranged in parallel at a predetermined interval in the culm transport direction. This is to prevent the waste straw from scattering onto the transfer route R' from the handling chamber 2, and the upper end of the scattering prevention member 23 is extended to a position where it acts on the waste straw transferred from the handling chamber 2. With this action, the structure is such that the so-called small grain paddy mixed in the waste straw is collected by flowing down to the receiver 18.

The collision member 20 is provided to be vertically swingable and fixed around the horizontal axis P1, and is configured to change and adjust the longitudinal position of the collision member 20 in accordance with the amount of processing material thrown out by the rotating body 19. be.

In the oscillating sorting plate 5, a straw rack 24 is provided to catch the processed material bounced back by the collision member 20.
... are arranged side by side, and the straw rack 24...
A sieve wire 25 for receiving the above-mentioned material to be processed is provided so as to be positioned between adjacent ones, respectively, in a state where they are integrally connected at the front end side, and the sieve wire 25 and the collision member 20 are connected to each other. The arms 26 and 27 are connected and interlocked in such a manner that their mounting angles can be changed.
The structure is such that the position of the sieve wire 25 is integrally changed with the change of the position of the collision member 20, and the sieve wire 25 reliably receives the material to be processed that has been bounced back by the collision member 20.

In the present invention, the collision member 20 may be configured to be slidable in the front-rear direction in order to change its position.

Further, the present invention can also be applied to a type of threshing and sorting device that does not include the processing chamber 4.

In summary, the present invention provides an opening 1 formed on the terminal end side of the handling chamber 2 in the transfer direction in the above-mentioned threshing and sorting device.
A receiver 18 for the threshed material discharged from 6 and the handling barrel 1
A rotary body 19 is driven and rotated around a horizontal axis Q that is substantially perpendicular to the rotation axis P of the rotary body 19, and releases the threshed material on the receiver 18 toward the downstream side in the transfer direction. The thrown threshing products are transferred to the straw rack 24 in the sorting section.
... is located between the collision member 20, which is installed so as to bounce upwards and whose rebound position can be changed freely, and the straw rack 24, which is located between adjacent ones of the straw racks 24... The present invention is characterized by comprising a sieve wire 25 for receiving the threshed material.

In other words, the threshed material falling from the handling room 2 is transferred to the receiver 1.
8 , the objects to be processed are bounced off the collision member 20 by the rotating body 19 and supplied onto the straw rack 24 .
Even if the supply is concentrated in some areas,
By rebounding from the collision member 20 mentioned above, grains can be dispersed to the front, back, left and right of the straw rack 24, and the grain sorting performance of the straw rack 24 can be improved.

Moreover, since the position of the collision member 2'3 can be changed, when the amount of straw waste is small, the collision member 20 can be moved closer to the rotary body 19, so that regardless of the fluctuation in the amount of straw waste, the collision member 20 can be moved closer to the rotating body 19. In addition to being able to uniformly and dispersely supply the straw waste to the rack 24, for example, when the amount of straw waste is small, the collision member 20 is positioned further away than the rotating body 19, and the entire material to be processed is supplied to the terminal end side of the straw rack 24, This avoids an unexpected shortening of the length of the sorting action, and allows for good sorting in conditions suitable for each amount of straw waste. Moreover, rotating body 1
In the releasing action of the threshed material by 9 and the collision of the threshed material with the collision member 20, it is possible to thresh out the grains with branches in the threshed material, and the threshing performance is improved as a whole. , it has become possible to collect grains efficiently. Further, as described above, if the dispersion is due to rebound from the collision member 20, while the dispersion effect is good, there is a concern that the straw waste may slip between the straw racks when the threshed material collides with the straw racks, resulting in poor sorting. However, in the present invention, a sieve line is provided in the part of the straw rack where the threshed material bounces back, and the gap for filtration is made small, so the above-mentioned poor sorting can be prevented and the grains as a whole can be improved. This has the effect of making collection more efficient.
