[0001] This utility model relates to the field of rice processing technology, and in particular to a multi-field synergistic rice impurity separation device. Background Technology

[0002] Rice is paddy rice, which is a finished product made from paddy rice through processes such as cleaning, hulling, milling, and finishing. The germ and aleurone layer of paddy rice contain nearly 64% of the rice's nutrients and more than 90% of the nutrients required by the human body, making it a staple food for people. During rice processing, it is necessary to separate impurities from the rice. The existing rice impurity separation devices have the following drawbacks in practical use: In existing rice impurity separation devices, the filter screens that block rice husks are easily blocked by rice husks, which affects ventilation and consequently the separation of rice husks. Utility Model Content

[0003] In view of the technical problem in the prior art that the filter screen of the rice impurity separation device is easily blocked by rice husks, which affects ventilation and thus affects the separation of rice husks, this utility model provides a multi-field synergistic rice impurity separation device.

[0004] The technical solution adopted by this utility model is: a multi-field collaborative rice impurity separation device, including an impurity separation box. The impurity separation box contains a rice husk separation component, which includes a first lifting plate, a second lifting plate, a mounting base, a shaft, an isolation net, and a collection box. The first and second lifting plates are both fixedly mounted on the inner wall of the impurity separation box, with the first lifting plate positioned above the second lifting plate. The mounting base is fixedly mounted on the outer wall of one side of the impurity separation box, and a support rod is fixedly mounted on the inner wall of the mounting base. A motor is fixedly mounted at the other end of the mounting base. One end of the shaft is mounted on the output shaft of the motor. Several fan blades are mounted on the outer wall of the shaft near the motor. A cleaning brush is fixedly mounted at the other end of the shaft away from the motor. The isolation net is mounted on the outer wall of the impurity separation box. The shaft is rotatably connected to the isolation net through a bearing. The collection box is fixedly mounted on the outer wall of the impurity separation box. A filter screen is mounted on the outer wall of the collection box. The cleaning brush is in contact with the filter screen. A collection box is inserted inside the collection box.

[0005] Furthermore, the impurity separation box is equipped with a particle screen inside, and a discharge seat is fixedly installed on the inner wall at the bottom of the impurity separation box, while a feed hopper is fixedly installed on the top of the impurity separation box.

[0006] Furthermore, an anti-clogging component is provided on the inner wall of the impurity separation box near the particle screen. The anti-clogging component includes a transmission frame, a moving block, and a cleaning roller brush.

[0018] The following is in conjunction with the appendix Figures 1-5 The present invention will be further described below.

[0019] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a multi-field synergistic rice impurity separation device.

[0020] The specific technical solution includes an impurity separation box 1, inside which a rice husk separation component 2 is installed. The rice husk separation component 2 includes a first lifting plate 201, a second lifting plate 202, a mounting base 203, a shaft 206, an isolation net 208, and a collection box 209. The first lifting plate 201 and the second lifting plate 202 are both fixedly installed on the inner wall of the impurity separation box 1, with the first lifting plate 201 located above the second lifting plate 202. The mounting base 203 is fixedly installed on the outer wall of one side of the impurity separation box 1, and a support rod 204 is fixedly installed on the inner wall of the mounting base 203. A motor 205 is fixedly installed at the other end of the support rod 204 away from the mounting base 203. One end of the shaft 206 is installed on the output shaft of the first motor 205. A plurality of fan blades 212 are provided on the outer wall of the rod 206 near the motor 205, and a cleaning brush 207 is fixedly provided on the other end of the rod 206 away from the motor 205. An isolation net 208 is provided on the outer wall of the impurity separation box 1, and the rod 206 is rotatably connected to the isolation net 208 through a bearing. A collection box 209 is fixedly provided on the outer wall of the impurity separation box 1, and a filter screen 210 is provided on the outer wall of the collection box 209. The cleaning brush 207 is in contact with the filter screen 210. A collection box 211 is inserted inside the collection box 209. The rice husk separation component 2 is used to separate the rice husks mixed in with the rice and can clean the filter screen 210 to prevent the rice husks from adhering to the filter screen 210 and affecting ventilation and rice husk separation.

[0021] In specific implementations, such as Figure 1 and Figure 2 As shown, the impurity separation box 1 is equipped with a particle screen 3 inside, and a discharge seat 4 is fixedly installed on the inner wall of the bottom of the impurity separation box 1. A feed hopper 6 is fixedly installed on the top of the impurity separation box 1. The particle screen 3 is used to screen and separate the particles in the rice. The top surface of the discharge seat 4 is inclined to facilitate discharge.

[0022] In specific implementations, such as Figure 1 , 2 4 and Figure 5 As shown, an anti-clogging component 5 is provided on the inner wall of the impurity separation box 1 near the broken grain screen 3. The anti-clogging component 5 includes a transmission frame 501, a moving block 502 and a cleaning roller brush 505. The anti-clogging component 5 is used to self-clean the broken grain screen 3 and can prevent rice broken grains from clogging the broken grain screen 3.

[0023] Furthermore, the transmission frame 501 is fixedly installed on the inner wall of the impurity separation box 1 near the particle screen 3, and the moving block 502 is slidably connected inside the transmission frame 501, so that the transmission frame 501 can guide the moving block 502.

[0024] Furthermore, a second motor 503 is fixedly mounted on one end of the transmission frame 501, and a lead screw 504 is mounted on the output shaft of the second motor 503, which can drive the lead screw 504 to rotate.

[0025] Furthermore, the movable block 502 is threaded onto the outside of the lead screw 504, and the two ends of the cleaning roller brush 505 are rotatably connected to the outer walls of the two movable blocks 502 through bearings, which enables the movable block 502 to move axially on the lead screw 504. When the movable block 502 moves, it will drive the cleaning roller brush 505 to move.

[0026] Furthermore, both ends of the cleaning roller brush 505 are provided with gear rings 506 located inside the transmission frame 501. A rack 507 is fixedly provided on the inner wall of the top of the transmission frame 501, and the gear rings 506 and rack 507 mesh with each other, enabling the gear rings 506 and the cleaning roller brush 505 to rotate.

[0027] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview: In operation, rice is fed into the impurity separation box 1 through the feed hopper 6. The rice first falls down along the lifting plate 1 201, then onto the lifting plate 202, and then down again. The motor 1 205 is turned on, driving the shaft 206 to rotate. The shaft 206 then drives the fan blades 212 and the cleaning brush 207 to rotate. Because the rice husks are lighter than the rice, the rotating fan blades 212 blow the rice husks mixed in with the rice into the collection box 209. The filter screen 210 filters and blocks the rice husks, causing them to fall into the collection box 211. The shaft 206 drives the cleaning brush 207 to clean the filter screen 210, preventing rice husks from adhering to it and affecting ventilation and rice husk separation. Furthermore, the two-stage rice husk separation process ensures a more thorough separation of the rice husks. Rice falls onto the grain-breaking screen 3, where broken grains are separated. Combined with rice husk separation, this multi-stage synergy achieves efficient impurity removal, improving the impurity removal rate and precision. It also shortens the processing time and increases efficiency. Starting motor 503 drives the lead screw 504 to rotate, causing the moving block 502 to move axially on the lead screw 504. The movement of the moving block 502 drives the cleaning roller brush 505 to move. As the cleaning roller brush 505 moves, its toothed ring 506 meshes with the rack 507, causing the cleaning roller brush 505 to rotate. This simultaneous movement and rotation of the cleaning roller brush 505 cleans the grain-breaking screen 3, preventing rice grains from clogging the mesh and achieving a self-cleaning function. This eliminates the need for frequent machine shutdowns and manual cleaning of the grain-breaking screen 3, making it more convenient.
