A belt 70 which is a conductor is wrapped around 67, 68 and 69 to form an interlocking structure. Therefore, the power input shaft 5 of the rotary grain sorting device 3 is connected to the coupling 8 by the power output shaft 4 of the hulling device 1.
Rotationally driven through. The rotation of this power intake shaft 5 is
The power is transmitted to the conveyor shaft 63 of the dehulling section supply trough 46 which rotates integrally with the power intake shaft 5, and all drive parts of the rotary grain sorter 3 are driven by a single conductor belt 70.
By pulley 64. Pulley 67°68 and 6
The rotational information is transmitted through the conveyor shaft 65 of the finished rice receiving trough 50, the conveyor shaft 66 of the mixed rice receiving trough 53, and the rotational information 37 of the supporting driving wheel 38.
As a result of the rotation, the sorting tube 2 is rotated in the direction indicated by the arrow, and the screw conveyor 47 of the mixed rice supply 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 fed from the supply port 12 into the dehulling chamber 9 by the unhulled feed roll 14, and is dehulled by the fixed dehulling roll 10 and the operating dehulling roll 11, and then sorted. In the air passage 30, the rice husks are sucked up by the suction dust remover 28, become a husking section, and reach the husking section transfer gutter 31, and this husking section is transferred by a screw conveyor 33, and is transferred by a rotary grain lifting machine 35. The grain is fried into three hoppers of the grain sorting device 3 and sent from the supply ports 48 of the three hoppers to the dehulling section supply gutter 46.
is supplied to the front end (left end in Figure 1), and its terminal end (
It is supplied to the sorting start end side (right end in FIG. 1) of the sorting tube 2 from the supply port 45 at the right end in FIG. 1 (right end in FIG. 1).

The dehulled rice supplied into the sorting tube 2 is transferred to the sorting end side (the left end in FIG. 1) by the rotation of the sorting tube 2, and the finished rice with a high specific gravity in the dehulled portion sinks. It fits into the recess a and is scooped up, passes over the receiving plate 51 and falls into the finished rice receiving gutter 50, is transferred by the screw conveyor 49 and falls from the flow path 54 into the finished rice transfer gutter 55, and then is transferred to the screw conveyor. The grains are transferred by a grain lifting machine 61, fried by a grain lifting machine 56, and taken out of the machine. In this way, the mixed rice from which the finished rice has been removed and whose finished rice ratio has decreased is transferred to the mixed rice receiving trough 5.
3 and was transported by the screw conveyor 52,
The grain falls from the flow path 57 into the dehulling section transfer gutter 31, is transferred together with the dehulling section from the hulling device 1 by the screw conveyor 33, is fried by the grain loss machine 35, and is sent to the hopper of the rotary grain sorting device 3. 39. After removing the finished rice, almost only unhulled rice falls into the paddy transfer gutter 59 from the sorting end of the sorting n2 through the flow path 58, is transferred by the screw conveyor 62, and is lifted by the grain lifting machine 60. The grains are shredded and supplied to the supply hopper 13, and are dehulled together with the unhulled rice in the supply hopper 13 in the dehulling chamber 9.

Therefore, when removing the residual rice remaining in the rotary grain sorter W3 at the end of the work, or when performing maintenance on the drive device at6 of the rotary grain sorter W3, it is necessary to Type grain sorting device if3 is installed in wind sorting section 2
After loosening the knob bolt 42 fixed on the top, pull the handle 44 and pull out the rotary grain sorter 3 along the guide rail 4o of the wind sorter flt 36 to perform cleaning work or maintenance of the rotary grain sorter 3. You can work easily.

As is clear from the above explanation, since the entire transmission device of the rotary grain sorting device is located in the transmission space between the hulling device and the rotary grain sorting device, the machine body can be made compact. However, when the rotary grain sorting device is moved to the set position of the machine, the end of the power take-off shaft on the hulling device side and the end of the power intake shaft of the rotary grain sorter may come into contact with each other. Since the connection position is via a coupling, the end of the power take-off shaft on the side of the rotary grain sorting device and the end of the power take-off shaft on the side of the hulling device and the end of the power intake shaft on the side of the rotary grain sorter are set on the machine body. This makes it easy to connect to other parts.
