Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided with a rocking / sorting section provided with a chaff sheave for sorting down threshes while transferring a threshed material in one direction, below a handling room.
The present invention relates to a sorting unit structure of a threshing device in which the chaff sheave is composed of a plurality of strip-shaped members arranged side by side in a horizontal posture intersecting with a transfer direction of the threshed product.

[0002]

2. Description of the Related Art In a conventional threshing device, each of a plurality of strip-shaped members constituting the chaff sheave is formed of a plate member having no holes (for example, Japanese Patent Laid-Open No. 5-95728).

[0003]

Generally, in the sorting section structure of this type of threshing apparatus, threshing from a grain pan that is disposed on the upstream side in the transfer direction with respect to the threshed material and chaff sheaves leaking from the handling room. The processed product is received by a chaff sheave, and by swing selection in that state, the grains in the threshed processed product are leaked and supplied to the grain sieve and the like through the gap between the strip-shaped members arranged in parallel. However, conventionally, since each of the band-shaped members of the chaff sheave is composed of a plate member having no hole, a part of the grain falling between the adjacent band-shaped members hits the plate surface of the band-shaped member and splashes upward. It was sometimes skipped, which was one of the causes of the deterioration of the leakage selection performance. In particular, in recent years, speeding up threshing work, or a combine equipped with this type of threshing device,
There is a demand for speeding up the cutting and threshing work, and if this demand is met, the processing amount per unit time in the rocking and sorting unit will increase significantly, and as a result, the threshing received on the chaff sheaves will be increased. A large amount of grains falling from the processed material and a large amount of grains hitting the plate surface of the belt-like member and being splashed upward collide with each other, and become close to a retention state, and many grains are out of the machine along with straw waste. The loss that is emitted will also increase.

The present invention has been made in view of the above-mentioned circumstances, and even if the threshing treatment amount per unit time in the rocking sorting section is increased by increasing the speed of the threshing action, the loss is small. It is an object of the present invention to provide a sorting unit structure of a threshing device capable of favorably performing the leakage screening.

[0005]

The characteristic structure of the present invention for achieving the above object is to provide a shaker provided below the handling chamber with a chaff sieve for sorting the threshing material while transferring it in one direction. With a dynamic sorting unit, the chaff sheave is a sorting unit structure of a threshing device configured by a plurality of strip-shaped members arranged side by side in a horizontal posture intersecting the transfer direction of the threshed material. That is, each of the strip-shaped members is provided with a large number of grain leakage holes.

[0006]

With the rocking / sorting motion of the rocking / sorting section, a part of the grains falling from the threshing-treated product on the chaff sheave falls through the space between the plurality of strip-shaped members constituting the chaff sheave, and remains. A part of the grains of the above is leaked through a large number of holes provided in each of the strip-shaped members. Therefore, it is possible to reduce the amount of grains that are splashed upward by the band-shaped member.

[0007]

As a result, even if the threshing work amount per unit time in the rocking sorting unit is increased by improving the speed of threshing work by improving the leakage selection performance of chaff sheaves, the leakage will occur with less loss. It is possible to sort down.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a combine threshing device for loading combine, in which a handling chamber 1 and a dust treatment chamber 2 are formed in the upper half of the device, and a sorting treatment chamber 3 is formed in the lower half of the device. In the handling chamber 1, a handling drum 4 is installed which is rotatably driven around a horizontal axis along the front-rear direction, and below the handling barrel 4, a net for leaking the treated threshing products is leaked. 5 are arranged. As shown in FIG. 2, the sorting chamber 3 has a handling chamber 1
From the receiving net 5 and an opening formed in the rear of the receiving net 5, the throttling and sorting unit 6 that sorts the threshing-treated product while transferring it to the rear, and the sardine 7 that produces the sorting wind and the sorting process. A collecting section 8 for collecting the first and second items is provided.

The rocking / sorting section 6 is provided with left and right side plates 9A of a sorting case 9 which is swingably driven with respect to the threshing machine frame.
Glen pan 10 for specific gravity selection of threshed products
And a chaff sheave 11 for rough sorting for grain selection in threshing products, a grain sieve 12 for fine sorting for grain selection in threshing products, and a chaff sheave 11 at the rear position of the grain pan 10. It is provided with a Straw rack 13 for sieving and sorting the grains in the straw sent out from. Then, the threshing-treated product leaking from the handling room 1 is subjected to specific gravity selection by the Glen pan 10,
Roughly selecting with the chaff sheave 11, finely selecting with the gren sieve 12, and collecting the grain that leaks in the glen sieve 12 as the first thing in the first thing collecting part 8A of the collecting part 8 and the end part of the gren sieve 12 and the straw rack. The processed product in which the grains and straw scraps falling from 13 are mixed is collected as a second product in the second product recovery unit 8B of the recovery unit 8.

The chaff sheave 11 is composed of a plurality of strip-shaped members 14 arranged side by side in a horizontal posture intersecting (orthogonal to) the transfer direction (front-rear direction) of the threshed material. As shown in FIG. 3, each of the lower end portions 14 of the
A is composed of a plate member having an L-shaped cross section that is folded back to the front, and the vertically oriented plate portion 14 of these plate members 14
In each B, a large number of grain leakage holes 15 having a size that allows the grains to pass therethrough are formed in two rows in the upper and lower rows at a predetermined pitch in the lateral direction. Also, each of the plate members 14
Is attached to both side plates 9A of the sorting case 9 so as to be swingable around a horizontal axis P, and the mounting angle can be changed according to the amount of processing per unit time. .

As shown in FIG. 2, the grain sheave 12 is curved and formed in an arc shape, which is located lower toward the center in the transfer direction of the threshed material.

[Other Embodiment] In the above embodiment, the belt-shaped member 1 is used.
4 is composed of a plate material having holes 15, but is not limited to this structure, and, for example, as shown in FIG. 4, a cross formed with a mesh having a size that allows grains to pass therethrough. It may be formed by a crimp net 16 having an L-shaped surface,
Further, as shown in FIG. 5, the lower end portion 16 of the crimp net 16 is
A may be reinforced with the frame member 17. Further, although the strip-shaped members 14 are arranged side by side in a horizontal posture orthogonal to the transfer direction of the threshed products, the strip-shaped members 14 may be arranged side by side in an inclined posture inclined forward and backward with respect to the transfer direction of the threshed products. Good.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
