Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a swing sorting device for sorting threshed grains of a threshing machine. The oscillating sorting device for threshing receives and sorts threshed grains leaking through the sorting net (2) part of the threshing room, and receives and sorts straw waste etc. discharged from the discharge port at the end of the threshing room. Although it is common for the parts μ to be sorted at different mesh sizes, it is better to change these mesh sizes depending on the type of threshing husk, the state of threshing, etc. to perform proper sorting. ,
In these cases, it is an object of the present invention to easily adjust the mesh size of the swing sorting device.

For this reason, the present invention has taken the following technical measures. That is, the leakage material that leaks through the sorting screen (2) of the threshing room (1) located below the threshing room (1) where the husks are threshed while transporting them, and the waste that is discharged from the discharge port (3) at the end of the threshing room (1). The oscillating sorting rack plate (4) receives and oscillates the straw waste, etc., and the oscillating material rack plate (5) receives and oscillates the waste material leaking from the sorting net (2). ), and waste rack plates (6) which are located before and after this leakage rack plate (5) and which receive and shake and sort waste such as straw waste discharged from the discharge a' (3). The threshing oscillating sorting device is constructed in such a manner that the angle (a) of the leakage rack plate (5) and the angle (b) of the waste rack plate (6) are operated in a related manner.

With this configuration, the present invention has the following technical effects. That is, among the threshed grains in the threshing room (1), threshed grains mainly leak through the sorting net (2) and are deposited on the leakage rack plate (5) of the swinging sorting shelf (4) directly below. After undergoing rocking sorting, the grains leak downward and straw waste etc. are rocked to the end of the rack plate (5), and
The straw waste etc. discharged from the discharge port (3) is collected on a swinging sorting shelf (
After passing through the discharge rack plate (6)-h in step 4), the grains leak downward and straw waste is transferred to the longitudinal end of the rack plate (6). If the inclination angle (a) of these leakage rack plates (5) is adjusted to be large or small depending on the sorting condition, the inclination angle (b) of the waste rack plate (6) can also be adjusted to be large or small. Since both adjustments can be made simultaneously and a certain relationship is maintained between the two adjustments, the sorting can be stabilized and the operation is simple and easy.

In addition, in the illustrated example, the swinging sorting shelf (4) is the threshing room (1).
