つた。Conventional technology In conventional color sorting machines, for example,
As shown in No. 86575, a light source and a light-receiving element are installed below the flow path to detect slight changes in the light intensity of different-colored particles mixed in grains, and the different-colored particles are scattered and separated by the blast from an air nozzle device. For those with a structure that allows grains to be sorted, as time passes during the sorting process, the rice bran adhering to the grains scatters onto the light source and light-receiving element's light-transmitting surfaces, causing them to become dirty and cloudy, resulting in a decrease in the amount of light emitted from the light source to the grains and the amount of light received. The amount of light received by the element may decrease and change, significantly interfering with color selection performance. Therefore, it is necessary to clean each light-transmitting surface of the photoelectric detection device in a timely manner.
However, in conventional color sorting machines, each base of the light source and light receiving element is fixedly installed in the machine box, so cleaning them requires a lot of effort. If the device is mounted in the same shape, cleaning each light-transmitting surface is extremely complicated, and requires disassembly, assembly, and maintenance each time. There was a problem that it was difficult to ensure satisfactory sorting accuracy due to the disorder.

置に復元する。Embodiments The present invention will be described with reference to embodiment figures. A particle flow down gutter 2 with a particle supply device 1 installed at the top is installed with a slight inclination, and the lower end of the particle flow down gutter 2 is connected to the particle sorting chamber 1.
Insert within 1. Photoelectric chambers 8 and 9 are arranged facing each other on the front and rear sides of the grain sorting chamber 11, respectively, and the downflow gutter 2
Light sources 4, 5 and 6, 7 for projecting light onto the accelerated particle stream 3 below the lower stage are installed horizontally inside each photoelectric chamber 8, 9, respectively. A dust-proof wall consisting of transparent windows 10 and 10 is provided on the surface of each photoelectric chamber 8 and 9 facing the grain sorting chamber 11, respectively, and the front and rear photoelectric chambers 8 and 9 are connected to the machine frame of the grain sorting chamber 11. By fitting from the outside into a support frame 13 provided at 12, each of the photoelectric chambers 8 and 9 is fixed to the grain sorting chamber 11 so as to be detachable from the outside. Further, each of the photoelectric chambers 8 and 9 is provided with a background ground 14 and 15, and a light receiving element 16 and 17 having a condensing lens, respectively.
The injection nozzle 21 of the injection nozzle device 20 is provided to blow jet air so as to scatter the detected particles, and the electromagnetic circuit 23 serving as a control device for the electromagnetic on-off valve 22 of the injection nozzle 21 of the injection nozzle device 20 is connected to each of the light receiving elements. I have contacted them on the 16th and 17th respectively.
Therefore, light is emitted from the light sources 4, 5, 6, and 7 in both photoelectric chambers 8 and 9 onto the particles flowing down in the grain sorting chamber 11, and light rays are reflected or transmitted from the different-color particles in the grains 3. When either of the light receiving elements 16, 7 detects the detection signal, the electromagnetic circuit 2
3 is activated, and furthermore, the electromagnetic on-off valve 22 of the injection nozzle device 20 is opened, and the detected particles are scattered and sorted by the blast of the injection nozzle 21, but at the same time, the dust attached to the particles is also scattered. This dust contaminates the outer surface of the transparent window 10, causing each of the light sources 4, 5 and 6 to
When the amount of transmitted light from the photoelectric chamber 7 is reduced and the sorting performance deteriorates, you can easily remove the photoelectric chamber 8 by grasping the handle 24.
The transparent window 10 is exposed outside the machine frame and cleaned. After cleaning, the photoelectrolyte 8 is reinserted in the opposite direction to restore it to its normal position.

る。Effects By isolating the grain sorting room and the photoelectric detection device using the transparent window provided on the side facing the grain sorting room of each photoelectric chamber, the photoelectric detection device is protected from dirt, and
If the transparent window that faces the narrow grain sorting room and is out of reach becomes contaminated with dust, the entire photoelectric detection device including the photoelectric chamber is exposed outward, making it easy to thoroughly clean the transparent window. . In addition, since the base of each device of the photoelectric detection device is fixedly installed in the photoelectric chamber, the optical structural accuracy of each base will not be disturbed when the photoelectric chamber is moved, making it extremely easy and accurate. It can be assembled and disassembled and maintained, maintains the amount of light emitted from the light source of the photoelectric detection device constant, and maintains the detection sensitivity of the light receiving element normally.
This has the effect of reliably exhibiting a highly accurate sorting action.

きる。 Furthermore, since light is emitted from both sides of the particles to be sorted, and the light is received and detected on both sides, changes in the shape, position, color, etc. of the particles to be sorted can be detected more reliably than when the particles are detected on one side. It can be done.
