Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a swing sorting case for transporting and sorting a processed material from a handling chamber with driving swing, and a chaff sheave having a large number of chaff plates arranged in parallel in the transported direction of the processed material. The present invention relates to a sorting section of a combine threshing device.

[0002]

2. Description of the Related Art Conventionally, the angle of each chaff plate is remotely changeable from the outside in order to adjust the chaf sheave mesh size. It is possible to remove some of the processed material that has become clogged.

[0003]

However, in the case where the treated product is so wet that the grain culms harvested in the early morning or after rain are targeted, as shown in FIG.
0 adheres to the upper end side of the chaff plate 34 in a state where it extends over a plurality of chaff plates 34, and even if all the chaff plates 34 are integrally rocked, the intervals between the upper ends of the chaff plates 34 are constant, so that the chaff plates 34 are layered. Solidified product 4
It was difficult to destroy and drop 0, and there was room for further improvement in terms of improving sorting performance. An object of the present invention is to reliably destroy and drop a solidified processed product even if the processed product solidified in layers adheres to the upper end side of the chaf plate in a state where it extends over a plurality of chaff plates. This is to effectively prevent the clogging of the processed material in the above.

[0004]

A characteristic configuration of the present invention is that a plurality of chaff plates are arranged in parallel in a processing object transfer direction in a swing selection case for transferring and selecting a processing object from a handling chamber according to a drive swing. In the combine provided with the chaff sheave, the chaff plate is attached such that a part of the chaf plate is vertically movable relative to the rest, and an operation means is provided for vertically moving a part of the chaff plate and the rest. It is in.

[0005]

That is, when a part of the chaff plate and the remaining part are moved up and down relatively by an artificial or automatic operation means, the chaff plate adheres to the upper end side of the chaff plate in a state of covering a plurality of chaff plates and is solidified in layers. The processed product can be destroyed, and the destroyed processed product can be easily dropped by rocking the chaff sheave. Therefore, even if the processed product easily hardens due to wetting, etc., it is caused by the adherence of the processed product to the chaff sheave. It is possible to reliably prevent clogging of chaff sheaves and improve grain recovery efficiency sufficiently and reliably.

[0006]

As a result, even if wet culms such as those in the early morning or after rain are to be treated, it is possible to effectively prevent clogging of the treated products in the chaff sheaves, which is a more excellent combine condition in terms of harvesting conditions and sorting performance. It is now possible to provide a threshing device.
