[0002] During the rice production process, some impurities such as stones and sand may get mixed into the rice due to harvesting, polishing, and drying. In addition, some rice may have problems and may have adverse effects on human health after consumption. Therefore, these impurities need to be removed by rice color sorting machine before consumption.

[0003] In existing technologies, rice is typically poured into the feed inlet manually, which increases the labor intensity of workers, affects their work efficiency, and generates significant noise during color sorting. Furthermore, color sorting usually only occurs once, resulting in poor sorting quality. To address these issues, application number 202111093993.8 discloses a rice color sorter. This machine includes a first discharge pipe and a discharge pipe arranged from left to right at the bottom of the main body.

[0028] Reference Figures 1-5 A rice color sorter includes a base plate 1, a rice color sorting device 3, and a feeding mechanism;

[0029] The base plate 1 is provided with four support legs 2, and the same rice color sorting device 3 is fixedly connected to the four support legs 2. The rice color sorting device 3 is provided with a feeding mechanism, and a control panel 13 is fixedly installed on the rice color sorting device 3. The feeding mechanism is connected to the control panel 13. The rice color sorting device 3 can achieve the effect of color sorting rice, and the screened impurities and rice are discharged through two discharge pipes on one side. The specific structure and working principle of the rice color sorting device 3 can be referred to the literature with application number: 202420591874.8. This is the prior art and will not be described in detail.

[0030] The feeding mechanism includes a fixed plate 4, a rotating shaft 5, a transmission wheel 6, a conveyor belt 7, a square sleeve 8, a feed hopper 9, a screen 10, and a motor 11. Fixed plates 4 are fixedly connected to both sides of the rice color sorting device 3. A rotating shaft 5 is rotatably connected to each of the two fixed plates 4. The same conveyor belt 7 is mounted on both rotating shafts 5, and a square sleeve 8 is slidably fitted onto the conveyor belt 7. Through the coordinated design of the rice color sorting device 3, control panel 13, rotating shaft 5, transmission wheel 6, conveyor belt 7, square sleeve 8, screen 10, and motor 11, not only can the quantitative conveying of rice be achieved, preventing rice accumulation from affecting the color sorting effect of the rice color sorting device 3, but it can also achieve the preliminary screening effect of larger impurities in the rice, thus improving the screening effect.

[0031] In this embodiment, the top of the square sleeve 8 is sealed with a feed hopper 9, and the bottom of the square sleeve 8 is fixedly installed with a screen 10. The screen 10 corresponds to the feed inlet at the top of the rice color sorting device 3. When the rice is transported to the position corresponding to the screen 10, the screen 10 can perform preliminary screening of larger impurities in the rice. At the same time, the rice passes through the screen 10 and falls into the feed inlet at the top of the rice color sorting device 3, thereby achieving the effect of automatic feeding. It also avoids the accumulation of rice, which would affect the color sorting effect of the rice color sorting device 3.

[0032] In this embodiment, a motor 11 is fixedly installed on the rice color sorting device 3. The motor 11 is connected to one of the two rotating shafts 5. The motor 11 is connected to the control panel 13 and is used to drive the conveyor belt 7 to rotate.

[0033] In this embodiment, both ends of the two rotating shafts 5 are fixedly connected to transmission wheels 6, and all four transmission wheels 6 are connected to the conveyor belt 7. The conveyor belt 7 is in contact with the rice color sorting device 3 for transmission. The conveyor belt 7 rotates through the cooperation between the four transmission wheels 6 and the conveyor belt 7.

[0034] In this embodiment, the conveyor belt 7 has multiple through holes arranged at equal intervals. Through the cooperation between the multiple through holes and the square sleeve 8, the conveyor belt 7 achieves the effect of quantitatively conveying rice.

[0035] In this embodiment, a gear is fixedly connected to the output end of the motor 11, and a gear ring is meshed on the gear. The gear ring is fixedly sleeved on one of the two rotating shafts 5. Through the cooperation between the gear and the gear ring, the motor 11 drives the corresponding rotating shaft 5 to rotate on the fixed plate 4.

[0036] In this embodiment, an arc plate 12 is fixedly installed on one side of the rice color sorting device 3. The arc plate 12 is in contact with the conveyor belt 7. The arc plate 12 can prevent the screened impurities from falling into the inner side of the conveyor belt 7.

[0037] In this embodiment, a collection box 14 is provided on the base plate 1. The collection box 14 corresponds to the conveyor belt 7 and is used to collect larger debris that has been screened out by the collection box.

[0038] In this embodiment, all four drive wheels 6 are adapted to the square sleeve 8, the conveyor belt 7 is adapted to the square sleeve 8, and the square sleeve 8 is fixedly connected to the rice color sorting device 3, which is a detachable connection.

[0039] In this embodiment, bearings are fixedly sleeved on both rotating shafts 5, and the outer walls of the two bearings are fixedly connected to the two fixed plates 4 respectively, so as to facilitate the rotation of the two rotating shafts 5.

[0040] Working principle: During use, the motor 11 and the rice color sorting device 3 are driven and controlled through the control panel 13;

[0041] First, rice is fed into the feed hopper 9 and the motor 11 is started. Driven by the motor 11 and the gear and gear ring, the corresponding rotating shaft 5 rotates on the fixed plate 4 and drives the two corresponding transmission wheels 6 to rotate synchronously. At this time, the four transmission wheels 6 and the conveyor belt 7 rotate through the cooperation between them. Since the conveyor belt 7 has multiple through holes, the rice in the feed hopper 9 passes through the square sleeve 8 and falls into the multiple through holes. Thus, the conveyor belt 7 conveys the rice through the multiple through holes.

[0042] When the rice is conveyed to the position corresponding to the screen 10, the screen 10 can perform a preliminary screening of larger impurities in the rice. At the same time, the rice passes through the screen 10 and falls into the feed inlet at the top of the rice color sorting device 3, thus achieving the effect of automatic feeding. This also prevents the rice from piling up and affecting the color sorting effect of the rice color sorting device 3.

[0043] Subsequently, the conveyor belt 7 transports the larger impurities that have been screened to the collection box 14 through multiple through holes. When the multiple through holes are perpendicular to the collection box 14, the impurities in the multiple through holes will fall into the collection box 14, thereby achieving the effect of collecting the impurities.

[0044] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, not only can the quantitative conveying of rice be achieved, avoiding the accumulation of rice which would affect the color sorting effect of the rice color sorting device 3, but it can also achieve the preliminary screening effect of larger impurities in the rice, thus improving the screening effect. Moreover, the structure is simple and the practicality is higher.
