Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rocking / sorting device of a threshing machine, in which straw debris mixed in grains after threshing is separated and removed by a chaff sieve and a Glen sieve of a swinging / sorting disc.

[0002]

2. Description of the Related Art Normally, a grain sieve part is composed of a crimp net, and wind from Kara Minato is applied to the grain after leaking through the crimp net to selectively remove dust such as straw dust in the grain. ing.

[0003]

However, in the case of a crimp net, since the mesh is fixed and the sorting capacity is limited, the upper chaff sheave (side angle) can be used to cope with the mixing of cuts and the like. However, there is a drawback in that the loss increases and the wind cannot be effectively blown against the leaked substances from the chaff sheaves, so that the selection allowable amount also decreases accordingly.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention is a swinging sorting board provided with a chaff sheave for separating and removing straw debris from threshing grains, and is formed by a horizontal rod below the chaff sheave and substantially above the first conveyor. By arranging the grain sieve for adjusting the inclination angle, it is possible to reduce the mixing ratio of culm and the like contained in the first sorted product and improve the processing capacity. Also, between the chaff sheave and the Glensieve is formed as a sorting wind passage that allows the wind from the Karato to flow, and by providing two upper and lower Karatochi sorting wind passages on the upper and lower sides of the Glen Sieve, the leakage from the chaff sheave can be prevented. On the other hand, the wind can be effectively applied to increase the selection allowance to improve the processing capacity, and moreover, the ventilation angle between the upper and lower sheaves can be adjusted by adjusting the lateral angle of the gren sheave. The range of application to materials and the like can be expanded.
