[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] For examples, please refer to Figures 1-5 This utility model provides a technical solution:

[0026] A high-precision broken rice grading and color sorting device includes a grading box 1, a kneading component 4 inside the grading box 1, a top cover 2 on the top of the grading box 1, an inlet 3 through the top of the top cover 2, an observation window 17 on the side of the grading box 1, and a support leg 16 fixedly connected to the bottom of the grading box 1.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the kneading assembly 4 includes a first electric telescopic rod 401 and a second electric telescopic rod 405, which are respectively fixedly connected to the inner wall of the grading box 1. A first motor 402 and a second motor 406 are respectively fixedly installed on the sides of the first electric telescopic rod 401 and the second electric telescopic rod 405. A first extrusion plate 403 and a second extrusion plate 407 are respectively fixedly connected to the output ends of the first motor 402 and the second motor 406. A first elastic sponge pad 404 and a second elastic sponge pad 408 are respectively fixedly connected to the sides of the first extrusion plate 403 and the second extrusion plate 407. The first elastic sponge pad 404 and the second elastic sponge pad 408 are in contact. A first guide groove 5 is fixedly connected inside the grading box 1. The first guide groove 5 is located at the bottom of the first elastic sponge pad 404 and the second elastic sponge pad 408. A first sieve plate 6 is connected inside the first guide groove 5. A first vibrating block 7 is fixedly connected to the top of the first sieve plate 6. A second guide groove 9 is provided at the bottom of the first guide groove 5.

[0028] The system incorporates a kneading assembly 4, a first guide groove 5, a first sieve plate 6, a first vibrating block 7, and a second guide groove 9. This design removes impurities from the surface of broken rice and performs coarse sieving, thus pre-treating the rice for grading and improving grading efficiency. During operation, broken rice enters the grading box 1 through the feeding port 3 and falls between the first elastic sponge pad 404 and the second elastic sponge pad 408 for processing. The first motor 402 and the second motor 406 control the first extrusion plate 403 and the second extrusion plate 407 to rotate in opposite directions, thereby driving the first elastic sponge pad 404 and the second elastic sponge pad 408 to knead the rice, removing dust and impurities from the surface. The rice then falls into the first guide groove 5, where the first sieve plate 6 and the first vibrating block 7 sieve out larger impurities and broken rice particles, allowing the rice that meets the composite sieving standards to enter the guide groove 9. This facilitates subsequent grading and color sorting, improving overall efficiency.

[0029] In this embodiment, as Figure 2 , Figure 4 and Figure 5As shown, a color sorting detection element is installed inside the second guide groove 9. A fan 10 is fixedly connected inside the grading box 1. An air outlet 11 is provided on the side of the fan 10. A grading assembly 12 is installed inside the grading box 1. The grading assembly 12 includes an inclined plate 1201 fixedly connected to the inner bottom wall of the grading box 1. The side of the inclined plate 1201 is fixedly connected to the inner bottom wall of the grading box 1 through a reinforcing plate 1202. A second vibration block 1203 is fixedly connected to the side of the inclined plate 1201. A second sieve plate 1204 and a third sieve plate 1205 are fixedly connected to the side of the inclined plate 1201. A first outlet 8 and a second outlet 18 are provided on the side of the grading box 1. The first outlet 8 and the second outlet 18 are respectively connected to the second sieve plate. 1204 and the third sieve plate 1205 are fixedly connected. T-shaped limiting blocks 19 and support plates 23 are provided on the side of the grading box 1 at the positions corresponding to the first outlet 8 and the second outlet 18. A collection box 20 is provided on the top of the support plate 23. A sliding groove 21 is opened on the side of the collection box 20. The sliding groove 21 and the T-shaped limiting block 19 are slidably connected. An outlet groove 22 is provided on the side of the collection box 20. The inclination angle of the outlet groove 22 is equal to the inclination angle of the second sieve plate 1204. A through groove is opened at the bottom of the grading box 1. A fixing block 13 is fixedly connected to the bottom of the grading box 1. A first pull groove 14 and a second pull groove 15 are slidably connected on the side of the fixing block 13. The first pull groove 14 and the second pull groove 15 are respectively corresponding to the through groove.

[0030] The system incorporates a fan 10, an air outlet 11, a grading component 12, a first pull-out groove 14, a second pull-out groove 15, and a collection box 20 to achieve grading and color sorting of broken rice. When broken rice passes through the second guide groove 9, the color sorting detection element within the second guide groove 9 performs color sorting. When non-compliant broken rice is detected, the color sorting detection element's air control mechanism 10 blows the non-compliant broken rice to the side, causing it to fall into the first pull-out groove 14 for collection. Compliant broken rice falls to the top of the second sieve plate 1204 for grading and screening. Through the second sieve plate 1204, the third sieve plate 1205, and the second vibrating block 1203, the compliant broken rice is divided into three grades, which are then collected separately through the second pull-out groove 15 and the collection box 20, thereby improving the efficiency and accuracy of grading.

[0031] The working process of this utility model is as follows: When the high-precision broken rice grading and color sorting equipment designed in this scheme is in operation, broken rice enters the grading box 1 through the feeding port 3 and falls between the first elastic sponge pad 404 and the second elastic sponge pad 408 for processing. The first motor 402 and the second motor 406 respectively control the first extrusion plate 403 and the second extrusion plate 407 to rotate in opposite directions, thereby driving the first elastic sponge pad 404 and the second elastic sponge pad 408 to rub, thus removing dust and impurities attached to the surface of the broken rice. Afterwards, the broken rice falls into the first guide groove 5, where it is screened out by the first sieve plate 6 and the first vibrating block 7, removing larger impurities and broken rice particles. The broken rice that meets the composite screening standard enters 9. When the broken rice passes through the second guide groove 9, the color sorting detection element in the second guide groove 9 performs color sorting operation on the broken rice. When broken rice that does not meet the standard is found, the air control mechanism 10 of the color sorting detection element works to blow the broken rice that does not meet the standard to the side, so that the broken rice that does not meet the standard falls into the first pull groove 14 for collection. The broken rice that meets the standard falls to the top of the second screen plate 1204 for grading and screening. Through the second screen plate 1204, the third screen plate 1205 and the second vibrating block 1203, the broken rice that meets the standard is divided into three grades, and then the broken rice of different grades is collected through the second pull groove 15 and the collection box 20 respectively.
