[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4, the utility model provides a technical solution: a walnut color sorting mechanism with sieve plate foreign matter removal, including a base 1 and a top plate 3. A support seat 2 is fixedly installed on the side of the lower end of the base 1. The base 1 and the top plate 3 are fixedly connected by a connecting frame. A material hopper 4 is fixedly installed on the upper end of the top plate 3 through a mounting frame. A material control structure is arranged at the lower end inside the material hopper 4. The material control structure includes a transmission shaft rod 41. The transmission shaft rod 41 is located at the lower end inside the material hopper 4. A distribution plate 42 is fixedly installed on the surface of the transmission shaft rod 41. Both the front and rear ends of the transmission shaft rod 41 are rotatably connected to the material hopper 4. A driving motor 43 is installed at the front end of the material hopper 4. The driving motor 43 is fixedly connected to the mounting frame. The output end of the driving motor 43 is fixedly connected to the front end of the transmission shaft rod 41. Four distribution plates 42 are distributed in a circular array around the transmission shaft rod 41. The walnuts are first poured into the material hopper 4, and then the walnuts slide down from the bottom of the material hopper 4 and land on the feeding plate 5. Feeding is achieved through the transportation of the feeding plate 5. The driving motor 43 drives the transmission shaft rod 41 to rotate, and the rotation of the distribution plate 42 controls the feeding. By controlling the rotation speed of the distribution plate 42, the discharge amount of walnuts in the material hopper 4 can be controlled, preventing excessive feeding and causing stacking of walnuts, which affects the color sorting effect;

[0024] A feeding plate 5 is arranged below the material hopper 4 inside the mounting frame. The lower end of the material hopper 4 is designed in a funnel-shaped structure. The right end of the feeding plate 5 is adapted to the lower end of the material hopper 4, and the left end of the feeding plate 5 is adapted to the upper end of the feeding sieve plate 6. An optical detection box 8 is arranged on the upper end of the base 1. A feeding sieve plate 6 is arranged on the upper end of the optical detection box 8. A cleaning plate 7 is arranged at the left end of the feeding sieve plate 6. Sieve holes are formed on the surface of the feeding sieve plate 6. A cleaning top pin 71 is fixedly installed on the surface of the cleaning plate 7. The cleaning top pin 71 corresponds to the sieve holes one by one. Electric push rods 61 are installed at both the front and rear ends of the feeding sieve plate 6. The fixed ends of the electric push rods 61 are fixedly connected to the feeding sieve plate 6, and the output ends of the electric push rods 61 are fixedly connected to the cleaning plate 7. An outlet pipe 9 is fixedly installed on the surface of the optical detection box 8. A detection groove is arranged at the upper end of the surface of the optical detection box 8. The lower end of the feeding sieve plate 6 extends into the detection groove. A color sorting sensor is arranged inside the optical detection box 8. There are two outlet pipes 9. One ends of the two outlet pipes 9 are connected to the optical detection box 8, and the other ends of the outlet pipes 9 extend below the base 1. When the discharged walnuts slide on the feeding sieve plate 6 and pass through the optical detection box 8, the internal color sorting structure naturally senses the color of the walnuts, thereby realizing sorting. The qualified walnuts flow out through one of the outlet pipes 9, and the unqualified walnuts are sorted into the other outlet pipe 9. At the same time, the feeding sieve plate 6 is cleaned by the cleaning plate 7. The electric push rod 61 drives the cleaning plate 7 to move, so that the cleaning top pin 71 enters the sieve holes, avoiding blockage of the sieve holes by impurities, and removing foreign matters on the feeding sieve plate 6, ensuring the adhesion between the walnuts and the feeding sieve plate 6 during transportation, and preventing the formation of bridging of walnuts during feeding.

[0025] During operation, the walnut kernels are first poured into the material hopper 4, and then the walnut kernels slide down from the bottom of the material hopper 4 and fall onto the feeding plate 5. Feeding is achieved through the conveyance of the feeding plate 5. The drive motor 43 drives the transmission shaft rod 41 to rotate, and the rotation of the material distribution plate 42 controls the feeding. By controlling the rotation speed of the material distribution plate 42, the discharge amount of the walnut kernels in the material hopper 4 can be controlled to prevent excessive feeding, resulting in stacking of the walnut kernels and affecting the color sorting effect. After discharging, the walnut kernels slide on the feeding sieve plate 6. When passing through the optical detection box 8, the internal color sorting structure naturally senses the color of the walnut kernels, thereby achieving sorting. The qualified walnut kernels flow out through the discharge pipe 9 on one side, while the unqualified walnut kernels are sorted into the discharge pipe 9 on the other side. At the same time, the cleaning plate 7 is used to clean the feeding sieve plate 6. The electric push rod 61 drives the cleaning plate 7 to move, so that the cleaning ejector pin 71 enters the sieve holes, preventing impurities from blocking the sieve holes, removing foreign matters on the feeding sieve plate 6, ensuring the adhesion between the walnut kernels and the feeding sieve plate 6 during conveyance, and preventing the formation of bridging of the walnut kernels during feeding.
