Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gutter body fixing device for a color sorting machine, which finely adjusts the inclination angle of a plurality of inclinations and arranged in parallel for each of the gutter separately. The purpose is to accurately fix the downflow gutter in a predetermined position, thereby ensuring high sorting accuracy.

A conventional color sorting machine of this type is disclosed in Japanese Patent Application Laid-Open No. 47-2616.
As shown in Figure 6, different color particles are separated by detecting changes in the amount of light obtained by projecting light onto the particles flowing down into the photoelectric sorting chamber along a fixed trajectory from multiple flow channels installed in parallel at an angle. However, since the angle of inclination of each of the plurality of drainage channels cannot be finely adjusted individually, the velocity and constant trajectory of particles flowing down from each of the plurality of drainage channels cannot necessarily be the same for each of the plurality of drainage channels. It cannot be set, and there is a drawback that the sorting accuracy decreases in relation to the timing of separation of different color particles in the photoelectric sorting chamber.

To explain the present invention with reference to an embodiment diagram, a plurality of vibrating grain feeders 3 equipped with a vibrating device 2 are installed in the upper part of a sorting machine frame 1, a supply hopper 4 is provided on the supply side thereof, and a supply hopper 4 is provided on the discharge side thereof. A plurality of downflow troughs 5 connected in the shape of a letter are arranged in parallel, and the lower end of each downflow trough 5 is connected to a sorting electrical equipment frame γ defining a photoelectric sorting chamber 6.

In the photoelectric sorting chamber 6, a light source 8 and a light-receiving element 9 are installed to direct the particles mixed with different-color rice into a certain trajectory AVc flowing down from each of the down-flow gutter 5.
In addition, an injection nozzle 10 is provided, and a grain collection barrel 11 is provided on the extension of the trajectory A, and an outlet 12 for discharging the different color particles is provided.

Then, a sorting appliance frame γ defining a photoelectric sorting chamber 6 is mounted in the sorting machine frame 1, and both sides 7A and 7B of the sorting appliance frame 1 are mounted.
extension walls 13A and 13B as connecting members are respectively erected, and a horizontal rod 15 is constructed between the upper ends thereof,
A plurality of gutter body fixing members 14 supporting each of the downflow gutter 5 are fixed to the horizontal rods 15.

The gutter body fixing member 14 connects the center of the arm rod portion 16 to the horizontal rod 15.
At the same time, a locking part 11 with a V-shaped opening is formed at the lower end to lock the downflow gutter 5, and a screw shaft 19 provided on the gutter body fixing part 18 is inserted into the upper end of the locking part 11, and the nut 20 It is equipped with a fine angle adjustment mechanism that allows fine adjustment of the inclination angle of the gutter body by moving it back and forth.

The gutter body fixing part 18 is formed so that the downflow gutter 5 is fitted into the notch and the cover plate 21 is screwed and fixed.

Reference numeral 22 denotes a gutter end insertion opening provided in the earthen wall of the sorting appliance frame 1.

Since the above-mentioned configuration is adopted, particles mixed with different color grains flowing out from the supply hopper 4 to each vibrating grain feeding trough 3 are removed from the vibrating grain feeding trough 3.
Due to the vibration effect, the liquid flows down into each of the lower downflow troughs 5 and slides down inside the photoelectric sorting chamber 6 along a constant trajectory A.

In the sorting chamber 6, a light source 8 emits light onto particles mixed with different color rice, and when a light receiving element 9 detects the light beam of the different color particles, a signal is emitted.
0 operates and blows air at the appropriate time, and the jet action causes the different-color particles to separate from the fixed trajectory M), and the separated particles flow down from the discharge port 12 and are removed, and continue to flow down along the trajectory A. The sorted grains are taken out of the machine via the grain collecting cylinder 11 and sent to the next process.

In the above-mentioned sorting process, when it is desired to attach a plurality of downflow troughs 5..., the lid plates 21 of each of the gutter body fixing members 14 fixedly attached to the horizontal rod 15 are unscrewed and the downflow troughs 5 are attached. 5 are individually fitted into the notches of the gutter body fixing part 18 and the locking part 17, respectively, and the ends of each gutter are fitted into the insertion openings 22 provided in the earthen wall of the sorting chamber form 7.

Then, when the cover plate 21 is screwed and fixed to the fixing member 14, each of the downflow gutters 5 is accurately fixed in a predetermined position by the rod 15, and each inclination angle is set to
Each can be finely adjusted individually by rotating forward and backward.

As described above, according to the present invention, a plurality of slanted and parallel drainage troughs are supported on the horizontal beam by a trough body fixing member equipped with an individual angle fine adjustment mechanism corresponding to each drainage trough. In addition, the inclination angle of each of the plurality of downflow troughs can be finely adjusted individually, and each of the downflow troughs can be accurately fixed at a predetermined position, thereby ensuring high sorting accuracy.
