In the device, dust and other particles adhere to the gutter surface of the downflow gutter due to the moisture content of the grains, impeding the smooth flow of the rice grains.As a result, even if the rice grains are under the same conditions, the permeation in each part of the rice grains is reduced due to the turbulence in the flow of the rice grains. This method has the drawback that the amount of received light changes, causing an error in light amount detection, which often reduces the accuracy and efficiency of detecting split grains.

It has been set up.
The split grain detection section A has a rotary disk 3 having a large number of detection windows 2 arranged on a circumference of the same diameter concentrically, rotatably attached to a hard shaft 4, and the hard shaft 4 connected to an electric motor 5. Select any detection window 2 of the disk 3 and arrange the light source 7 and light receiving elements 8, 9 of the photoelectric detection device 6 facing each other above and below the detection window 2. , each light-receiving element 8, 9 is provided at the irradiation point P above the window 2 of the detection device by means of optical fibers 10, 11, and is located at both front and rear sides of the vertical rice grain moving on the rotating disk 3. Each of the light receiving elements 8 and 9 is connected to a digital display 13 via a control circuit 12 by a conducting wire, and 14 is a rice grain provided on one side of the rotating disk 3. The cleaning body 14 sweeps out the rice grains on the disk 3 and drains them into the discharge gutter 1.
5 to be discharged outside the machine. Note that the light receiving elements 8 and 9 are optical fibers 1
0 and 11, and in this way, even if they are not structurally facing each other, but functionally facing each other, it is still considered to be "facing". It is assumed that Next, the rice grain feeding section B includes a vibrating grain feeding trough 17 which is provided with a grain feeding groove 16 that allows the rice grains to flow vertically and is installed in a horizontal structure, and supplies rice grains to one side of the vibrating grain feeding trough 17. 18 are arranged side by side and integrally formed, and the grain feeding gutter 18 is provided with a supply hopper 19 and a guide wall 20 on its inclined gutter surface, and the discharge port 21 on the higher side is connected to the row of the vibrating grain feeding gutter 17. The groove 16 is provided adjacent to the supply portion 22 on the starting end side, and the outlet 23 on the terminal end side of the groove 16 is provided adjacent to the rotation locus of the detection window 2 of the rotating disk 3.
