[0032] The elevator 4 has four trays 41 inside. The material is lifted to the feeding platform 19 through the trays 41. The material falls from the feeding platform 19 into the top of the feed hopper 5 and then into the two distributors 6. Through the uniform vibration of the vibrator 7, it is evenly distributed above the conveyor belt 8 and accelerates along the conveyor belt 8 through the two sorting boxes 1. Under the action of the jet valve 13, the finished product and waste material fall into the two material distribution troughs 9 respectively.

[0033] The upper part of the first frame 20 is provided with a conveyor belt 8, a sorting box 1, and a large electrical box 2; the sorting box 1 and the large electrical box 2 are installed on the front side of the conveyor belt 8;

[0034] A motor 22 is installed at the lower end of the first frame 20; the motor 22 is electrically connected to the large electrical box 2 and the sorting box 1.

[0035] The feeding platform 19 is connected to the top of the feeding hopper 5 via a baffle 23;

[0036] The second frame 21 is provided with a feeding hopper 5 at its top; the second frame 21 is provided at the top of the support plate 24; the upper end of the support plate 24 is also provided with an electrical plug 17.

[0037] The front side of the second frame 21 is equipped with a vibrator 7. The vibrator 7 is in contact with the feed hopper 5 and the distributor 6. The vibrator 7 vibrates to drop the material in the feed hopper 5 through the distributor 6 to the upper end of the conveyor belt 8.

[0038] The sorting box 1 is equipped with an LED light source 10, a CCD detection lens 11, a sensor 12, a background plate 15, and a signal processor 16.

[0039] There are two sorting boxes 1, which are symmetrically distributed on the upper and lower sides of the first frame 20; the lower end of the sorting box 1 is provided with two discharge ports 3; the lower end of the two discharge ports 3 is provided with two material distribution troughs 9 respectively.

[0040] An elevator 4 is installed on the side of the feed hopper 5; the feeding platform 19 is connected to the upper end of the elevator 4.

[0041] An air jet valve 13 is installed between the sorting boxes 1.

[0042] The vibrator 7 has a power socket 18 on one side, and the vibrator 7 is connected to the power strip 17 through the power socket 18. The power socket 18 and the power strip 17 are connected by a wire; there are two vibrators 7.

[0043] The CCD detection lens 11, sensor 12, signal processor 16, and jet valve 13 are electrically connected in sequence.

[0044] The LED light source 10 illuminates the material under test and produces different reflective properties, providing different reference signals for the background plate 15. The light signal is converted into an electrical signal by the sensor 12 and transmitted to the signal processor 16.

[0045] Each sorting box 1 is equipped with two LED light sources 10, one CCD detection lens 11, and one background plate 15.

[0046] The jet valve 13 is connected to the filter 14 via a pipe.

[0047] The photoelectric color sorter of this utility model also includes an air compressor, an air tank, and a refrigerated dryer / condenser. The air compressor, air tank, and refrigerated dryer / condenser are existing technologies and can be provided by the user. The compressed air output from the air compressor is cooled and then enters the air tank, where it is filtered by filter 14 before entering the air inlet of the color sorter. The air inlet is equipped with a ball valve, pressure gauge, filter 14, and pressure regulating valve. A portion of the gas is ejected after passing through a solenoid valve and a nozzle, effectively removing discolored materials. The remaining gas enters a rodless cylinder and a blow gun.

These discolored particles are then removed by pneumatic components, separating good and bad products. Generally, good products are pure colors, while bad products are mixed colors. In use, the equipment is connected to a power source, and the start switch of the main electrical box 2 is turned on. The elevator 4 lifts the material onto the feeding platform 19 via the tray 41. The material slides from the feeding platform 19 through the baffle 23 to the top of the feed hopper 5 and enters the color sorter. Through the uniform vibration of the vibrator 7, the selected material slides down the channel, accelerating its descent into the distributor 6 and is evenly distributed on the conveyor belt 8. The conveyor belt 8 rotates under the drive of the motor 22, and the material passes through the two sorting boxes 1. Under the influence of the LED light source 10, the background plate 15 reflects light according to the intensity and color change of the light. The CCD detection lens 11 receives the composite light formed by the reflection and transmission of the material, which is transmitted to the sensor 12. The sensor 12 transmits the signal to the signal processor 16, causing the signal processor 16 to generate an output signal to drive the jet valve 13 to blow out discolored particles. The defective waste material falls into the material distribution trough 9 at the lower end of one of the discharge hoppers 3, while the good finished material falls into another material distribution trough 9 at the lower end of the other discharge hopper 3, thus achieving the purpose of sorting. The photoelectric color sorter equipment of this embodiment can be widely used for sorting various grains such as broad beans, sunflower seeds, kidney beans, wheat kernels, red beans, mung beans, raisins, and watermelon seeds.
