Therefore, the power input shaft 5 of the rotary grain sorting device 3 is rotationally driven by the power output shaft 4 of the hulling device 1 via the coupling 8. The rotation of the power intake shaft 5 is transmitted to the conveyor shaft 63 of the threshing supply gutter 46 which rotates integrally with the power intake shaft 5, and all driving parts of the rotary grain sorting device 3 are driven by a single unit. conductor belt 7
0, pulley 64, pulley 67, 68
and 69 through the conveyor shaft 65 of the finished rice receiving gutter 50, the conveyor shaft 66 of the mixed rice receiving gutter 53, and the rotating shaft 37 of the support drive wheel 38, and by the rotation of the support drive wheel 38. As the sorting tube 2 is rotated in the direction of arrow b, the screw conveyor 47 of the mixed rice receiving gutter 46, the screw conveyor 49 of the finished rice receiving gutter 50, and the screw conveyor 52 of the mixed rice receiving gutter 53 are rotationally driven. .

Next, the operation of the above embodiment will be explained.

The unhulled rice supplied to the supply hopper 13 of the hulling device 1 is removed from the chamber 9 by the paddy feed roll 14 from the supply port 12.
The rice husks are sent into the interior and removed by the fixed removal rolls 10 and the operating removal rolls 11, and the rice husks are sucked up by the suction dust remover 28 in the sorting tray 30, become granules, and reach the granulation transfer gutter 31, where the husks are removed. The grain is transported by the screw conveyor 33 and
The grains are fried in the hopper 39 of the rotary grain sorting device 3 and supplied from the supply port 48 of the hopper 39 to the front end (left end in FIG. 1) of the threshing supply gutter 46,
It is supplied from the supply port 45 at the terminal end (left end in FIG. 1) to the sorting start end side (right end in FIG. 1) of the sorting tube 2.

The granules supplied into the sorting tube 2 are
While being transferred to the sorting end side (the left end in Figure 1) by the rotation of the , finished rice with a high specific gravity among the grains sinks, fits into the recess a, is scooped up, and passes over the receiving plate 51 to the finished rice receiving trough. 50, is transferred by the screw conveyor 49, falls from the flow path 54 into the finished rice transfer gutter 55, is then transferred by the screw conveyor 61, is fried by the grain lifting machine 56, and is taken out of the machine. It will be done. In this way, the mixed rice whose finished rice ratio has decreased by removing the finished rice,
The mixed rice falls into the trough 53 and the screw conveyor 5
2, the grains fall from the flow path 57 into the threshing transfer gutter 31, and are transported by the screw conveyor 33 along with the grains being shredded from the hulling device 1, and are fried by the grain lifting machine 35, and the grains are fried by the rotary grain sorting device 3. is supplied to the hopper 39. After the finished rice has been removed, the rice that is reduced to almost only unhulled rice falls from the sorting end of the sorting tube 2 through the flow path 58 into the paddy transfer gutter 59, is transferred by the screw conveyor 62, and is transferred to the grain lifting machine 60. The grains are fried and supplied to the supply hopper 13, and removed together with the unhulled rice in the supply hopper 13 in the removal chamber 9.

Therefore, when removing the residual rice remaining in the rotary grain sorting device 3 at the end of the work, or when performing maintenance on the drive device 6 of the rotary grain sorting device 3, it is necessary to Knob bolt 4 that fixes the type grain sorting device 3 on the wind sorting section 2
After loosening the rotary grain sorting device 2, the rotary grain sorting device 3 is pulled out along the guide rail 40 of the wind sorting section 2 by pulling the handle 44, thereby easily cleaning or maintaining the rotary grain sorting device 3. Can be done.

As is clear from the above explanation, a power intake shaft whose shaft center coincides with one drive shaft portion of the rotary grain sorting device and which rotates integrally is provided protrudingly, and the power intake shaft and the power intake shaft are connected to each other. Since the axes of the shaft and the rotary grain sorting device are aligned and are freely connected via a coupling ring, the configuration of the power intake shaft is simplified, and the power intake shaft and other parts of the rotary grain sorting device can be A single conduction band is used to transmit power between all drive shaft parts of the rotary grain sorter, which streamlines and simplifies the power transmission structure from the power intake shaft to other drive parts of the rotary grain sorter. It is possible.

Note that this invention is not limited to the above-mentioned embodiment, and the invention can be implemented in modes other than the above-mentioned embodiment.
