[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Please refer to the appendix. Figures 1-4 The present invention provides a rice bran screening device for rice processing, comprising a box body 1, a first feed inlet 2 fixedly connected to the top of the side end of the box body 1, a rice grain discharge inlet 3 fixedly connected to the bottom of the box body 1, and a controller 4 fixedly connected to the front end of the box body 1. It should be noted that the controller 4 is electrically connected to an external 220V mains power supply. A striking component for separating rice grains and rice bran is fixedly installed inside the upper part of the box body 1, and an anti-clogging component is provided on the striking component. A screening component for screening rice grains and rice bran is fixedly installed inside the lower part of the box body 1. Both the striking component and the screening component are electrically connected to the controller 4.

[0023] The striking assembly includes a servo motor 5, which is vertically fixed at the top center of the housing 1. The servo motor 5 is electrically connected to the controller 4. The output shaft of the servo motor 5 vertically passes through the top of the housing 1. A rotating rod 6 is vertically fixed at the bottom of the output shaft of the servo motor 5. Several striking rods 7 are fixed on the surface of the rotating rod 6. Specifically, when the servo motor 5 is running, it can drive the several striking rods 7 to rotate at high speed through the rotating rod 6, thereby striking the rice added through the first feed port 2, so that the rice grains and rice bran are struck and separated inside the housing 1.

[0024] The striking assembly also includes a flow guide 8, which is funnel-shaped and has a discharge port 9 at the center of its bottom. Specifically, the rice grains and rice bran that are struck and separated inside the box 1 can be collected by the flow guide 8 and then discharged downward through the discharge port 9.

[0025] The anti-clogging component includes a feeding screw 10. The top of the feeding screw 10 is vertically fixed to the bottom of the rotating rod 6. The bottom of the feeding screw 10 vertically passes through the discharge port 9. Specifically, when the servo motor 5 drives the rotating rod 6 to rotate, it can also drive the feeding screw 10 to rotate synchronously, thereby actively pushing the rice bran and rice grains through the discharge port 9, which can effectively prevent the rice grains and rice bran from clogging when they are discharged at the discharge port 9.

[0026] The screening assembly includes a second feed inlet 11, which is fixedly connected to the side of the housing 1. The horizontal plane of the bottom of the second feed inlet 11 is located below the guide shroud 8. A guide plate 12 is fixedly inclined to the side of the inner wall of the housing 1, with the top of the guide plate 12 corresponding to the bottom of the second feed inlet 11. A bracket 13 is fixed to the bottom of the side of the housing 1, and a blower 14 is fixed to the top of the bracket 13. The blower 14 is electrically connected to the controller 4, and an air supply pipe 15 is fixedly connected to the output end of the blower 14. An air force regulating valve 16 is fixed to the body of the air supply pipe 15, and the end of the air supply pipe 15 passes through the side of the housing 1. A blower box 17 is fixedly connected to the main body, and a number of air outlets 18 are fixedly connected to the surface of the blower box 17. Specifically, rice grains and rice bran fed through the feeding port 9 or the second feeding port 11 can flow downward at an angle through the guide plate 12, so that the rice grains and rice bran are diffused during the flow. Then, the bottom end of the guide plate 12 diffuses downward, increasing the area of ​​air force contact. When the blower 14 is running, it can generate air force that enters the blower box 17 through the air pipe 15, and then blows it out through the number of air outlets 18, so that it can blow towards the rice grains and rice bran. The operator can control the required air force by controlling the air force regulating valve 16.

[0027] A rice bran outlet 19 is fixedly connected to the side of the box 1. The rice bran outlet 19 and the blower box 17 are located on the same horizontal plane. A rice bran collection bag 20 is fixedly connected to the end of the rice bran outlet 19. A rice grain collection box 21 is placed below the rice grain discharge port 3. Specifically, smaller rice bran can be blown into the rice bran collection bag 20 through the rice bran outlet 19, while larger rice grains flow downwards under the action of gravity and are discharged into the rice grain collection box 21, thus realizing the function of screening rice bran and rice grains.

[0028] The working principle of this utility model is as follows: First, rice grains and rice bran are separated by impact at the top inside the box 1. Then, the rice bran, which is smaller in mass, is blown into the rice bran collection bag 20 through the rice bran outlet 19 by wind power at the bottom inside the box 1. The larger rice grains flow downwards under gravity and are discharged into the rice grain collection box 21, thus achieving the function of separating rice bran and rice grains. Furthermore, the discharge through the outlet 9 effectively prevents blockage of rice grains and rice bran. Operators can observe the separation status of the rice grains and rice bran collected in the rice grain collection box 21. If the rice grains and rice bran are not fully separated... If the rice grains and rice bran in the rice grain collection box 21 are separated by impact, they can be added back into the box body 1 through the first feed port 2 for further impact separation and air screening. If the rice grains and rice bran are sufficiently separated by impact but not sufficiently screened by air, the air force can be increased by increasing the opening range of the air force regulating valve 16. Then, the rice grains and rice bran in the rice grain collection box 21 can be added back into the box body 1 through the second feed port 11 for further air screening. This allows for convenient secondary screening based on the different separation states of the rice grains and rice bran, thus improving the separation effect of rice grains and rice bran.

[0029] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
