2. Description of the Related Art In supplying grains from a mixed rice hopper of a hulling and sorting machine to an oscillating sorting device, an opening / closing valve that rotates about a single point as a fulcrum is provided at the bottom of the mixed rice hopper and this opening / closing is performed. The amount of grains to be fed was adjusted by adjusting the opening and closing of the valve.

[0003]

In the flow rate adjusting device for the mixed rice hopper configured as described above, the grain flow rate is not accurately adjusted, and a dust suction passage is connected to the upper part of the mixed rice hopper. However, there is a drawback that dust is scattered from the outflow portion of the grain and the working environment is deteriorated. Therefore, the present invention is intended to eliminate the drawbacks of the conventional device by specially connecting the dust suction passage to the feeding valve specially provided at the outlet of the grain hopper.

[0004]

The present invention takes the following technical means in order to solve the problems of the prior art. That is, according to the present invention, the feeding valve 36 is rotatably provided below the feeding channel 35 provided at the bottom of the supply hopper 22 for supplying the grains to be sorted, and the feeding channel 3 is provided.
5, the end of the dust suction passage 37 is exposed to the non-feeding rotation portion of the grain that rotates from below to above following the end of the above-mentioned rotation of the feeding valve 36 from above to below. This is a dust collecting device.
