The present invention relates to a device provided with a sorting device for sorting.

[0002]

2. Description of the Related Art In a conventional threshing machine, it has been attempted to separate a leaked material on a sorting device only by a transfer operation of the sorting device.

[0003]

However, according to the above-mentioned conventional technique, the sediment is separated by the transfer operation and the kernels are filtered and sorted in the grain sieve. Poor segregation cannot be exhibited because the posture change of the object is not so expected, and as a result, the sorting defects in which grain is not leaked to the collection part and transferred to the back with the straw chips in the grain sieve However, there is a drawback that it is easy to cause

An object of the present invention is to improve the sorting performance.

[0005]

The features, functions and effects of the first aspect of the present invention are as follows.

[Features] A threshing machine provided with a sorting device that sorts in a state in which grains in the leaked material are dropped while transferring the leaked material from the handling room in one direction. The point is that a selection promoting means for reciprocating a part or the whole in the left-right direction with respect to the transfer direction is provided.

According to the first aspect of the present invention, it is possible to move the leaked material on the sorting device in the left-right direction by the reciprocating movement of the sorting device in the left-right direction by the sorting promoting means. The synergistic effect of the transfer action and the movement action in the left-right direction can promote the change of the posture of the leaked object and improve the separability of the leaked object.

[Effects] Therefore, according to the first aspect of the present invention, by improving the separability of the leaked material, it is possible to improve the leakability of the grain in the grain sieve, and the straw is not filtered and sorted out. Sorting defects, such as being transported backward with the waste, can be reduced.

According to the second aspect of the present invention, the features, actions,
The effects are as follows.

[Features] In the features of the first invention,
As a means for promoting the selection, there is provided a means for reciprocating the grain sheave in the selection device.

[Action] What is strongly required for separability of a leaked material is a grain sieve of a sorting device that filters and sorts grains and collects them in a collecting section.

Focusing on the above points, according to the second aspect of the present invention, the grain sieve is reciprocated by the sorting facilitating means. The size and weight of the selection promoting means can be reduced as compared with the case of reciprocating.

[Effects] Therefore, according to the second aspect of the present invention, it is possible to implement at a low cost while exhibiting good sorting performance.

According to the third aspect of the present invention, the features, actions,
The effects are as follows.

[Features] In the features of the first and second aspects of the present invention, a means capable of adjusting a reciprocating speed is provided as the selection promoting means.

[Action] The degree of separation of the leaked material differs depending on the type of the leaked material such as rice and wheat, the degree of wetness / wetting of the leaked material, the amount of the leaked material, and the like. Reciprocating at a high speed when it is easy to do improves the grain leakage performance at the grain sieve, while the straw also makes it easier for the grain sieve to leak, and a large amount of An adverse effect such as mixing of straw waste occurs.

In view of the above points, according to the third aspect of the invention, the reciprocating speed can be adjusted.
For example, when the leaked material is difficult to separate, the reciprocating speed is increased and the leaked material is rapidly moved to enhance the separation action, so that the leaked material is difficult to separate. In addition, while it is possible to maintain good filtration separation in the grain sieve, when the leaked material is easily separated, the reciprocating speed is reduced or the reciprocating motion is stopped to weaken the separating action by the reciprocating motion. Thus, while the leaked material is easily separated, the selective filtration with the grain sieve can be performed satisfactorily in a state where the mixing of the straw waste is minimized.

[Effect] Therefore, according to the third aspect of the present invention, it is possible to satisfactorily separate leaky substances that are easy to separate from leaky substances that are difficult to separate, and to maintain high filtering and sorting performance in grain sieve. It became so.

According to the fourth aspect of the present invention, the features, functions,
The effects are as follows.

[Features] In the features of the first and second aspects of the present invention, there is provided a leak amount detecting means for detecting a leak amount on the sorting device, and the leak promoting amount detecting means is provided as the sorting promoting means. The point is that means is provided for automatically increasing the reciprocating speed as the detection amount of the means increases.

[Operation] According to the fourth aspect of the present invention, when the amount of the leaked substance required to promote the separation is large, the reciprocating speed is automatically increased, and the leaked substance is rapidly moved right and left. In the case where the degree of separation promotion is low or there is no request, the reciprocation speed is automatically reduced to lower the separation, or the reciprocation stops. As a result, the separation property according to the amount of the leaked material can be exhibited.

[Effects] Therefore, according to the fourth aspect of the present invention, appropriate separation according to the amount of leaked material is performed, and the filtration and sorting performance in the grain sieve is maintained high regardless of the fluctuation of the amount of leaked material. Now you can.
