Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a rocking / sorting section provided below a handling room and equipped with a Glen pan for receiving threshing material leaked from the handling room and sorting while swinging and transferring it. A plurality of sieve lines extending in a cantilever manner from the transfer end portion of the Glen pan toward the lower side in the transfer direction of the sorted products are juxtaposed to the swing sorting section, and the swing sorting section including the sieve line is provided. On the other hand, the present invention relates to the structure of the sorting section of the threshing device provided with Kara Minoh which supplies sorting wind.

[0002]

2. Description of the Related Art In the conventional sorting section structure of a threshing device, each of a plurality of sieving wires is made of an elastic rod-like member, and these sieving wires are fixed to the transfer end portion of the Glen pan.

[0003]

Considering the sorting process of this type of threshing apparatus, a plurality of sieving wires are integrally swung with the Glen pan, and the inertia force due to the swing of the Glen pan or the Glen pan is supplied from the Glen pan. By elastically flexing and deforming under the load of the threshed material, it promotes the separation of mixed grain and branched rice, straw debris, and straw that are entangled in the sorted material, and sorting in that state It was developed to enhance the efficiency of grain recovery while suppressing the inclusion of straw debris into the sorted material that leaks from between adjacent multiple sieve lines by the wind sorting effect of the wind. However, since the elastic deformation of the sieve wire itself is used, the flexural deformation amount of the sieve wire is likely to be restricted by its material, wire diameter, and the like.

The present invention has been made in view of the above circumstances, and an object thereof is to improve the separation effect of threshed products by the sieve wire by improving the attachment structure of the sieve wire. The point is to be able to.

[0005]

Means for Solving the Problems A characteristic feature of the present invention for achieving the above-mentioned object is a Glen pan for selecting a threshing material that has leaked from the handling room under the handling room and swinging and transferring it. An oscillating sorting section is provided, and a plurality of sliver lines extending in a cantilever manner from the transfer end portion of the Glen pan toward the lower side in the transport direction of the sorted products are juxtaposed to the oscillating sorting section. Along with the above, the sorting unit structure of the threshing device is provided with a Kara-mino which supplies the sorting wind to the swing sorting unit including the sieve wire, and all or part of the plurality of sieve wires can be vertically swung. In addition to the above configuration, a regulating portion for regulating the swing range of the vertically movable swing wire is provided.

[0006]

All of the plurality of sieve lines extending in a cantilever manner from the transfer end portion of the Glen pan toward the lower side in the transfer direction of the sorting object swing together with the swing sorting section and can swing freely. The sieve wire configured in Fig. 2 swings up and down in response to the inertial force caused by the swing of the swing sorting unit and the load of the threshing processed material supplied from the Glen Pan, and is complicated with respect to the threshing processed material on the sieve line. By imparting the motion, it is possible to promote the separation of the grain, the branched rice, the straw waste, and the straw that are mixed in the threshed product while being entangled with each other. Moreover, since all or part of the sieve line is configured to be vertically swingable, the shake that can effectively loosen the threshing material on the sieve line only by adjusting the positional relationship with the regulating portion. The range of motion can be easily expressed.

[0007]

Therefore, even if all or part of the above-mentioned sieve wire is vertically swingable, it is possible to easily improve the separation effect of the threshed product.
