Description

[Detailed Description of the Invention] [Industrial field of application] The present invention has a receiving net stretched below an axial flow type handling cylinder which is rotationally driven around a longitudinal axis, and below the receiving net. A swing sorting plate is provided, and a filter for coarse sorting corresponding to the front half of the handling cylinder is connected to the rear end of the front grain pan provided at the front end of the swing sorting plate. The present invention relates to a threshing device for an all-cule input combine harvester.

[Problems to be solved by the device]

The whole culm input type combine threshing device performs threshing selection of various stem culms such as rice, wheat and soybeans, but conventionally, soybean culms harder than rice and wheat are inserted into the pores of the filter body. There is a tendency for problems such as clogging to occur, and improvements have been desired.

 The purpose of the present invention is to eliminate the above-mentioned problems.

[Means for solving the problem]

According to the present invention, a receiving net is stretched below an axial flow type handling cylinder which is rotationally driven around a longitudinal axis, and a swing selecting plate is provided below the receiving net. At the rear end of the front Glen pan provided at the front end of the plate, in the threshing device of all culm throw-in type combine, which is provided with a filter body for rough sorting corresponding to the front half of the handling cylinder, It is characterized in that the filter hole in the filter for rough selection is configured to be able to be closed.

In addition, the filter body is fixedly attached to the rocking / sorting plate, and a plate body capable of closing the filter hole of the filter body is detachably provided in a state of being overlapped with the filter body, or the filter body is rocking / sorting. A plate body that is detachably attached to the plate and in which filtration of the processed material is impossible is provided so that it can be attached continuously to the rear end of the front grain pan, and both bodies can be attached to each other freely. Is also good.

[Action]

According to the configuration of claim 1, when threshing soybeans, the filter holes of the filter body are closed to prevent the rudder of the culm, and the clogging removal work of the filter body is eliminated, or the sorting performance is prevented from deteriorating. Like It was also confirmed that soybean has a better shedding ability than rice or the like, and thus the sorting performance is not likely to deteriorate even if the filtering function of rough sorting is omitted.

In addition, a coarse filtering effect can be produced by making the filter function when threshing rice, which is relatively difficult to shatter.

According to the configuration of claim 2, in addition to the above-mentioned action,
By fixing the filter body to the rocking sorting plate, the filter body itself becomes a structural member, and the strength of the rocking sorting plate can be improved.

According to the structure of claim 3, in addition to the effect of the structure of claim 1, both the filter body and the plate body can be attached and detached, so that both bodies can be easily kept clean by detaching and cleaning. .

[Effect of device]

Therefore, according to the configuration of claim 1, the selection performance of soybeans can be improved without deteriorating the selection performance of rice, wheat, etc., and the overall performance can be improved.

According to the configuration described in claim 2, in addition to the effect according to claim 1, there is an advantage that it is possible to contribute to the reduction of vibration and noise by the reinforcing action of the swing selection plate.

According to the structure of claim 3, in addition to the effect of claim 1, there is an advantage that the number 1 of the collected first product due to the selection can be reduced as compared with the conventional case, and the quality of the product can be improved.
