DISCLOSURE OF THE INVENTION In the conventional thresher,
Since the sorting case of the oscillating sorting unit is in a specific mounting posture with respect to the threshing case, the feed amount of the threshing treated product per swing of the sorting case becomes almost constant, and as a result, the threshing treated product However, there is a drawback that it is not possible to carry out an appropriate sorting process corresponding to the change in the flow rate per unit time. That is, the flow rate per unit time (thresholding amount) of the threshing processed product subjected to the swinging selection processing in the swinging selection unit is the granulation state of the threshing target grain kneaded into the handling room of the threshing device, and the unit. It greatly changes depending on the input amount of thresher to be threshed per hour. Then, conventionally, when the flow rate per unit time of the threshing-treated product increases by a set flow rate or more, a large amount of the threshing-treated product remains in the rocking sorting section, which may cause clogging. In addition, when the flow rate per unit time of the threshing processed product decreases by more than the set flow rate, the threshing processed product is There was a drawback that it was sent out at a constant speed.

The present invention has been made in view of the above situation, and thresher does not cause clogging even if the flow rate of the threshed material per unit time in the rocking / sorting unit changes, and the threshing does not occur. It is an object of the present invention to provide a structure of a sorting section of a threshing device capable of properly sorting processed products.

[0005]

The characteristic feature of the present invention for attaining the above object is that the swinging operation is performed below the handling room to sort threshing-treated products leaked from the handling room to the rear. A sorting unit is provided, and a swinging mechanism for swinging the sorting case is provided between the rear part of the sorting case and the threshing case of the swing sorting unit, and sorting is performed by driving the swinging mechanism. A guide member that guides the reciprocating movement of the front part of the case,
The threshing device has a sorting unit structure attached to a threshing case, and a changing mechanism for vertically adjusting the height of attachment of the guide member is provided in the threshing case.

[0006]

When the mounting height position of the guide member is changed downward by the changing mechanism, one of the sorting cases of the swing sorting unit is
The feed amount of the threshing-processed product is reduced due to the rocking per rotation, and, conversely, if the mounting height position of the guide member is changed to the upper position, the per unit of the sorting case of the rocking sorting unit is reduced. The feed rate of the threshing processed product in the swing selecting unit can be switched by adjusting the mounting height position of the guide member such that the feeding amount of the threshing processed product increases due to the rocking. Therefore, when the flow rate of the threshed product per unit time is large, the flow rate of the threshed product can be improved by increasing the feed speed in the rocking and sorting section, and the retention of the threshed product can be suppressed. Further, when the flow rate of the threshing processed material per unit time is small, the feeding speed in the swing sorting section is slowed down, so that the sorting time can be increased and the sorting accuracy can be improved.

[0007]

[Effects of the Invention] Therefore, even if the flow rate per unit time of the threshing processed material in the rocking / sorting section changes, proper rocking / sorting processing corresponding to the flow rate change is performed without causing clogging. be able to.
