DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer shelf, a plurality of chaff sheaves, and a plurality of straw racks from which a swing start is performed while receiving a threshing product and transferring the same to grains and straw chips. And each of the chaff sheave portions of a rocking shelving device including a rocking shelf and a Glen sheave below the chaff sheave is configured as a chaff sheave assembling device and is detachably mounted on the rocking shelter device. ), The length of the chaff sheave is made longer and the adjustment mechanism for adjusting the gap between the chaff sheaves is provided, and can be used as a sorting device for a threshing machine.

[0002]

2. Description of the Related Art Grains supplied to a threshing room of a threshing machine are:
Threshed kernels, some straw waste, and dust that are threshed during the transfer in the threshing chamber and leak from the threshing chamber, and unthreshed processed material that has not been threshed in the threshing chamber, and some straw waste , And the dust are supplied to the dust treatment chamber and threshed again, and the reprocessed grains, some straw waste, and dust, and the unthreshed processed material (second no. ) Is again threshed, and the reprocessed grains, some straw debris, and dust, all of which are supplied to a swinging sorting device provided in a sorting room below the threshing room, From the mountain-shaped transfer shelf at the beginning of transfer of the moving separation device, a number of chaff sheaves in the front-rear direction, a plurality of saw blade-shaped straw racks to the left and right, and a rocking shelf for downstream sorting are sequentially transferred and being transferred. Oscillating sorting, the oscillating sorted kernels leak from the mesh-shaped grain sieve under the chaff sheave, The cause air from the further air blower in the lower, and is discharged to the outside is the wind sorting.

[0003] The straw waste and dust that have been transferred to the transfer end of the straw rack while being sorted are sucked by a dust discharger and discharged outside the device.

[0004]

When the grain moisture value of the grain culm supplied to the threshing chamber of the threshing machine and threshed is high, the culm also has a high moisture value. When threshing a stalk of such a state, the generation of straw waste increases, which causes clogging of straw waste between each chaff sieve,
In addition, the mesh of the grain sieve may be clogged with straw debris, and the leakage of the grains may be poor, and the number of scatters may increase. For this,
It is necessary to perform a cleaning operation for removing straw debris from each of the chaff sheaves and the Glen sheave. However, since the Glen sheave is located under the respective chaff sheave, cleaning is particularly difficult. It tries to solve the point.
