Description

Technical Field

[0001] The utility model relates to the field of color sorters, in particular to a rice color sorter. Background Art

[0002] The rice color sorter is a machine that uses photoelectric technology to automatically sort out different-colored particles in rice based on the differences in the optical properties of rice, thereby improving the quality of rice and removing impurities. The material detection system is the core component of the color sorter. The material detection system is usually arranged in the chassis, and a transparent glass is set on the chassis to prevent foreign matter such as dust and debris mixed in the rice from adhering to the camera lens of the material detection system. After the color sorting work is completed, the foreign matter on the transparent glass is cleaned.

[0003] In the process of color sorting rice, it is difficult to clean foreign matter on the light-transmitting glass in time in a rice color sorting machine in the prior art, thereby reducing the recognition effect of the camera on rice and affecting the color sorting effect. Therefore, the utility model proposes a rice color sorting machine. Utility Model Content

[0028] Embodiment 1

[0029] See also Figures 1 to 4The utility model provides a technical solution: a rice color sorter, comprising a body 1, a feeding port 11 is arranged on the top of the body 1, and two sensors 2 are arranged inside the body 1;

[0030] A light-transmitting plate 21 is disposed on the side where the two sensors 2 are close to each other, and two groups of sponges 22 are disposed inside the body 1, and the sponges 22 of the same group are in contact with the side of the light-transmitting plate 21 away from the sensors 2;

[0031] The top of the light-transmitting plate 21 is fixedly connected with a transmission plate 23, and the transmission plate 23 is slidably connected to the inside of the body 1. A high-pressure air gun 24 is fixedly connected to the inner wall of the body 1;

[0032] Through slots are provided on both sides of the machine body 1 , and extrusion rods 26 are slidably connected inside the through slots. Two compression springs 25 are fixedly connected between the extrusion rods 26 , and the side of the extrusion rod 26 away from the compression springs 25 is fixedly connected to the sponge 22 .

[0033] Two motors 3 are fixedly connected to the top of the body 1, and two reciprocating screws 31 are rotatably connected to the inner wall of the body 1. The output ends of the motors 3 all penetrate the side walls of the body 1 and are fixedly connected to the reciprocating screws 31, and the transmission plates 23 are all threadedly sleeved on the outer walls of the reciprocating screws 31; two groups of slide bars 4 are fixedly connected to the inner wall of the body 1, and the transmission plates 23 are all slidably sleeved on the outer walls of the same group of slide bars 4; a large silo 5 and a small silo 51 are slidably connected to the inner bottom wall of the body 1, and the large silo 5 is located directly below the high-pressure air gun 24; a rectangular frame 6 is fixedly connected to the inner wall of the body 1, and the top of the rectangular frame 6 is tilted. By setting the rectangular frame 6, under the action of gravity, the rice slides downward along the inclined surface of the rectangular frame 6 to the inside of the large silo 5 and the small silo 51 to prevent the rice from remaining on the top of the large silo 5 and the small silo 51; a pull handle 7 is fixedly connected to the outer walls of the large silo 5 and the small silo 51.

[0034] In the present embodiment, during the color sorting process of rice, the motor 3 is started, the motor 3 drives the reciprocating screw 31 to rotate, and the reciprocating screw 31 drives the transmission plate 23 and the light-transmitting plate 21 to reciprocate up and down along the slide bar 4. Under the elastic action of the compression spring 25 itself, the compression spring 25 pushes the extrusion rod 26 and the sponge 22 to contact one side of the light-transmitting plate 21. During the contact between the light-transmitting plate 21 and the sponge 22, the sponge 22 cleans the foreign matter attached to the light-transmitting plate 21. Under the action of gravity, the rice moves downward through the discharge port 11 and passes between the two light-transmitting plates 21. The sensor 2 identifies the rice, and controls the high-pressure air gun 24 to blow out a high-pressure airflow to blow the rice with different colors. Under the blowing of the high-pressure airflow, the rice with different colors falls into the small silo 51, and under the action of gravity, the high-quality rice directly falls into the large silo 5. After the color sorting is completed, the large silo 5 and the small silo 51 are separated from the machine body 1 by pulling the handle 7, and the screened rice is taken out. Under the cleaning action of the sponge 22, foreign matter attached to the light-transmitting plate 21 is cleaned in time, thereby improving the recognition effect of the sensor 2 on the rice and avoiding affecting the color sorting effect of the rice.
