Description

[Detailed Description of the Invention] [Industrial field of application] The present invention has a plurality of lip plate groups arranged in parallel in the left-right direction on the inner side of the rocking case, and further, the lip plates are arranged in parallel. The chaff sheave structure of the threshing device is configured so that the group can be swingably moved back and forth on both left and right sides by the swing case so that the opening can be adjusted.

[Conventional technology]

In the above structure, conventionally, a supporting member pivotally connecting the respective lip plates in order to swing the respective lip plate groups is provided on the outer side of the swing case (for example, the actual opening). 59-59838).

[Problems to be solved by the invention]

However, in the above conventional structure, when the lip plate groups are attached to the rocking case, the respective lip plate groups are individually swingably mounted to the rocking case, and then the outer side portion of the rocking case is attached. The rocking side portion of each lip plate group from the one side to the support member,
It must be attached so as to be pivotally connected individually, and the assembling work is extremely complicated, and a lot of drilling work is required for the rocking case, which increases the man-hours and the cost. Was becoming.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide a chaff sheave structure of a threshing device which makes the assembling work remarkably easy and further enables cost reduction.

[Means for solving problems]

A feature of the present invention is that in the chaff sheave structure of the threshing device, an upper pivot member that pivotally connects the left and right upper ends of each lip plate group and a lower pivot member that pivotally connects the left and right lower ends of One of the lip plate groups is arranged on the inner side of the rocking case so that either the upper pivot member or the lower pivot member is attached and fixed to the rocking case. On the side swinging side pivotal support portions of the two lip plates, engaging pins that project outward from the side portions of the swinging case through elongated holes formed in the swinging case are provided to An operating member that engages with the engaging pin and can swing each lip plate group is provided on one side, and the operation and effect are as follows.

[Action]

When each of the lip plate groups is attached to the rocking case, the pivot support members are attached to the lip plate groups in advance, and the lip plate groups are assembled as an integrated assembly. It can be attached and fixed to. Therefore, since small parts such as each pivot member and lip plate are preassembled to form an assembly, it is not necessary to assemble a large number of parts directly to the swing case, which is a large part, and the assembly work is easy. It becomes. Moreover, it is sufficient to form a single long hole in the swinging case for the operation member to engage with the single engagement pin, and the drilling work is significantly reduced.

[Effect of device]

Therefore, the assembling work becomes extremely easy, the working time can be shortened, the part processing time can be shortened, and the cost can be reduced.

〔Example〕

FIG. 5 shows the threshing device (1) mounted on the combine. This threshing device (1) grips the root side of the harvested culm by the threshing feed chain (2) and conveys it, while handling the tip side by the handling cylinder (3) driven to rotate and threshing. In addition to the above, the threshing processed product leaks through the receiving net (4) below the handling cylinder (3), and sifting is selected by the rocking sorting device (5). Dust such as straw chips is blown upward in the rear by the sorting air supplied from 6).

And the selected grain is the No. 1 product recovery screw below
