CONSTITUTION:The vibration classifier 5 for threshed product is equipped with a grain sieve for the grain-passing through classification, as the product is placed on and conveyed, further provided with a means for changing the shape of the grain-passing through classification face 20 of the grain sieve to increase or decrease the resistance to the moving threshed product on the face 20.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a swinging sorter for selecting a processed product with a grain sieve for picking down grains from the processed product while placing and moving the processed product. Regarding threshing equipment.

[0002]

2. Description of the Related Art In a conventional threshing device, a leaking sorting surface of a grain sieve is fixed in a fixed shape.

[0003]

Therefore, regardless of the supply amount of the processed product to the Glen sieve, the processed product moves on the Glen sieve at a substantially constant speed, and the supplied amount of the processed product to the Glen sieve. If there is a large amount, those treated products have a drawback that they pass over the Glensieve without sufficient leakage screening being performed.

In order to solve this drawback, for example, when the swing sorter provided with the Glensieve is configured so that the mounting angle with respect to the machine can be changed, and the supply amount of the processed material to the Glensieve is large, the swinging is performed. By changing the mounting angle of the dynamic sorter to the machine body, it is possible to change the gradient of the grain sheave along the processing object moving direction and move those processing objects on the Glensive at a low speed. There is a drawback that the processing speed of the processed material is also changed at the same time.

The present invention has been made in view of the above circumstances, and by improving the grain sieve, it is possible to adjust the amount of the treated material supplied to the grain sieve without affecting the processing rate of the treated material in the front and rear positions of the grain sieve. In this way, it is possible to make it possible to perform sufficient leakage screening for those treated products.

[0006]

Means for Solving the Problems A characteristic feature of the present invention for attaining the above object is that a processed product is placed on an oscillating sorting body for sorting the processed product and moved while the grain is removed from the processed product. It is a threshing device provided with a Glensieve for sorting down grain, and it is possible to change the shape of the downstream sorting surface of the Glensieve to change the movement resistance of the processed object along the downstream sorting surface to increase or decrease. It is the point that the changing means is provided.

[0007]

[Function] When the amount of the processed product supplied to the Glensive is large, the movement resistance of the processed product along the leakage screening surface can be increased without changing the mounting angle of the swing screening device provided with the Glensieve to the machine body. When the amount of the processed products supplied to the Glen Sieve is small, the movement resistance of the processed products along the leakage screening surface is reduced to increase the amount of the processed products to be processed. Objects can be moved on the Glensieve at a relatively high speed.

[0008]

As a result, sufficient leakage screening is performed on the processed products according to the amount of the processed products supplied to the Glen sieve, without affecting the processing speed of the processed products in the front and rear positions of the Glen sieve. Can be made.

[First Embodiment] FIG. 1 shows a threshing device mounted on a combine, and a thresher A for threshing a cut culm held by a feed chain 1 from the front side of the machine and a threshing treatment A. A sorting device B that sorts and processes grains from the threshed product is provided, and the handling chamber A, the receiving net 3 through which the threshed product leaks, and the handling chamber A remain in the handling chamber A. A dust supply port 4 for discharging the threshing processed material to the side of the sorting apparatus B is provided, and the sorting apparatus B is provided with a swinging sorting body 5 for sorting the threshing processed material leaked from the handling chamber A and a sorting wind. A karakono 6 which blows air is provided, and the collection parts 7 and 8 are arranged below the rocking sorting body 5.

The swing selecting body 5 extends over the upper portions of the left and right side plates of the sheave case 9 by the Glen pan 10 and the chaff sheave 1.
1, the Straw rack 12 is fixed, and the auxiliary Glen pan 13 and the Glen sheave 14 are fixed over the lower portions of the left and right side plates, and a support shaft 15 is provided on the front side of the sheave case 9 to support the support. The shaft 15 is supported so as to be reciprocally slidably movable in the vertical direction along a guide plate 16 fixed to the machine body side, and the rear part of the sheave case 9 is supported by an eccentric shaft 17 provided on the machine body side for eccentricity. When the shaft 17 is driven and rotated, the swing selecting body 5 is configured to swing in the up-down direction and the front-rear direction about the support shaft 15 as a fulcrum.

Then, after the processed material leaking from the receiving net 3 is subjected to specific gravity selection by the Glen pan 10, the chaff sheave 11
Is roughly sorted and dropped onto the Glensieve 14, and the processed material dropped onto the Glensieve 14 is sorted to the rear side of the machine while the grain is sorted down, and the sorted grain is the best grain. As the second processed product, the grain that has been collected to the first product recovery unit 7 and discharged to the outside of the machine, has fallen over the end portions of the straw rack 12 and the Glensieeve 14, and is mixed with straw waste, etc. It collects to the thing collection part 8 and the handling room A is used by the thrower 18.
Is reduced to.

The gren sheave 14 is composed of a plurality of laterally elongated wire nets 19 arranged in the longitudinal direction of the machine body, which are swingably connected to each other so as to be flexibly deformable in a zigzag manner along the longitudinal direction of the machine body.

Based on the detection result, the supply amount of the processed material to the grain sieve 14 is determined, and the drive motor 27 is increased or decreased according to the increase or decrease of the supply amount.
A control device 29 for driving the vehicle is provided on the machine body side.

When the amount of the processed material supplied to the grain sieve 14 is large, the relief deformation of the pantograph mechanism 21 increases the ups and downs of the leakage selection surface 20 to increase the movement resistance of the processed material along the leakage selection surface 20. Is controlled to move on the Glensieeve 14 at a low speed, and when the amount of the processed matter supplied to the Glensieeve 14 is small, the pantograph mechanism 21 is stretched and deformed to cause the leakage selection surface 20 to rise and fall.
