[0024] Refer to Figures 1 - 4, a rice crushing device, comprising a housing 1. A feed inlet is provided at the top of the housing 1. Inside the housing 1, at a position below the feed inlet, there is a crushing component for crushing rice. Rice is added into the housing 1 through the feed inlet, and then crushed by the crushing component. Inside the housing 1, there is a U-shaped frame 12 passing through the housing 1. On both sides of the housing 1, two first sliding grooves 4 are provided. A fixing block 3 is slidably connected in each of the multiple first sliding grooves 4, and the fixing block 3 is fixed to the U-shaped frame 12. On one outer wall of the housing 1, there is a power component for moving the U-shaped frame 12 up and down reciprocally. Inside the U-shaped frame 12, a second filter screen 21 inclined and passing through the housing 1 is fixed by bolts. Two sliding openings are provided at the bottom of the second filter screen 21. A sliding rail 17 is slidably connected in each of the two sliding openings. The bottom of the sliding rail 17 is welded with a first filter screen 16, and the filter holes of the first filter screen 16 are aligned with those of the second filter screen 21. The crushed rice pieces will fall onto the second filter screen 21, so that the filter holes on the second filter screen 21 and the first filter screen 16 screen the rice pieces. At the same time, the power component drives the U-shaped frame 12 to move up and down reciprocally. At the bottom of the second filter screen 21, there is a driving component for driving the first filter screen 16 to move. At the same time, the first connecting block 18 is moved through the driving component. The first connecting block 18 drives the first filter screen 16 to move along the sliding opening through the sliding rail 17, so that the filter holes on the first filter screen 16 are misaligned with those on the second filter screen 21 to change the size of the filter holes, thereby filtering and screening rice pieces of different sizes. There is no need to perform secondary screening on the rice pieces, saving time and the cost of the enterprise. An outlet is provided at the bottom of the housing 1. At the bottom of the housing 1, there is a material collecting component for collecting rice.

[0025] In the present utility model, the crushing component includes two crushing rollers 10. Both of the two crushing rollers 10 are rotatably connected inside the housing 1. One end of each of the two crushing rollers 10 passes through the housing 1 and is respectively key-connected with a first gear 11 and a second gear 15. The first gear 11 and the second gear 15 are meshed with each other. On one outer wall of the housing 1, a mounting frame is fixed by bolts. Inside the mounting frame, a motor is fixed by bolts. One end of the output shaft of the motor is fixed to the first gear 11. When the motor is started, the motor drives the first gear 11 to rotate. The first gear 11 drives the second gear 15 to rotate in the opposite direction through meshing with the second gear 15, and the first gear 11 and the second gear 15 drive the two crushing rollers 10 to rotate, so that the crushing rollers 10 crush the rice.

[0026] Particularly, the power assembly includes a fixing frame 2 which is fixed to the outer wall of one side of the housing 1 by bolts. A reduction motor is fixed in the fixing frame 2 by bolts. A second chute 7 is formed in one side of the housing 1. A fixing column 9 is slidably connected in the second chute 7 and is fixed to the U-shaped frame 12. One end of the output shaft of the reduction motor is key-connected to a turntable 22. A plurality of push rods 8 for pushing the fixing column 9 to move upward along the second chute 7 are welded to the outside of the turntable 22. Springs 5 are arranged in a plurality of first chutes 4, and both ends of each spring 5 are fixed to the fixing block 3 and the housing 1 respectively. Guide rods 6 are fixed to the plurality of first chutes 4 by bolts, and the guide rods 6 pass through the springs 5 and the fixing blocks 3. When the reduction motor is started, the reduction motor drives the turntable 22 to rotate. The turntable 22 drives the push rods 8 to rotate. During the rotation of the push rods 8, the push rods 8 push the fixing column 9 to move upward along the second chute 7. The fixing column 9 drives the U-shaped frame 12 to move upward. The U-shaped frame 12 drives the fixing block 3 to move upward along the first chute 4. The fixing block 3 compresses the spring 5. When the push rod 8 rotates away from the fixing column 9, at this time, under the action of the spring 5, the fixing block 3 moves downward, so that the U-shaped frame 12 moves downward. In this way, the U-shaped frame 12 drives the first filter screen 16 and the second filter screen 21 to move up and down reciprocally, so that the first filter screen 16 and the second filter screen 21 can better screen the rice fragments;

[0027] The driving assembly includes a second connecting block 19 which is welded to the bottom of the second filter screen 21. A first connecting block 18 is welded to one side of the first filter screen 16. A threaded hole is formed in one side of the second connecting block 19. A lead screw 20 is threadedly connected in the threaded hole and is rotatably connected to the first connecting block 18. When the lead screw 20 is rotated, the lead screw 20 moves through the threaded engagement with the threaded hole. The lead screw 20 drives the first connecting block 18 to move. One end of the lead screw 20 passes through the housing 1 and is welded with a knob. The material receiving assembly includes two guide rails 14 which are both welded to the outer wall of the bottom of the housing 1. A collecting box 13 is slidably connected to the outside of the two guide rails 14. The two guide rails 14 are respectively located on both sides of the discharge port. The collecting box 13 is located directly below the discharge port. The rice fragments that pass through the screening will fall downward and thus enter the collecting box 13. The rice fragments that remain on the second filter screen 21 and do not pass through the screening will fall out of the housing 1. A magnet for adsorbing the collecting box 13 is welded to the outer wall of one side of the housing 1 at the bottom position. By adsorbing the collecting box 13 with the magnet, the collecting box 13 can be prevented from moving easily.

[0028] Working principle: When in use, rice is added into the housing 1 through the feeding port. At the same time, the motor is started, and the motor drives the first gear 11 to rotate. The first gear 11 drives the second gear 15 to rotate in the opposite direction through meshing with the second gear 15. The first gear 11 and the second gear 15 drive the two crushing rollers 10 to rotate, so that the crushing rollers 10 crush the rice. The crushed rice pieces will fall onto the second filter screen 21, and the filter holes on the second filter screen 21 and the first filter screen 16 screen the rice pieces. At the same time, the reduction motor is started, and the reduction motor drives the turntable 22 to rotate. The turntable 22 drives the lever 8 to rotate. During the rotation of the lever 8, it pushes the fixed column 9 to move upward along the second chute 7. The fixed column 9 drives the U-shaped frame 12 to move upward. The U-shaped frame 12 drives the fixed block 3 to move upward along the first chute 4. The fixed block 3 squeezes the spring 5. When the lever 8 rotates away from the fixed column 9, at this time, under the action of the spring 5, the fixed block 3 moves downward, so that the U-shaped frame 12 moves downward. This cycle is repeated, so that the U-shaped frame 12 drives the first filter screen 16 and the second filter screen 21 to move up and down reciprocally, enabling the first filter screen 16 and the second filter screen 21 to screen the rice pieces better. The rice pieces that pass through the screening will fall downward and thus enter the collection box 13, while the rice pieces that do not pass through the screening and remain on the second filter screen 21 will fall out of the housing 1. At the same time, the lead screw 20 can be rotated. The lead screw 20 moves through the threaded engagement with the threaded hole. The lead screw 20 drives the first connecting block 18 to move. The first connecting block 18 drives the first filter screen 16 to move along the sliding opening through the slide rail 17, so that the filter holes on the first filter screen 16 are misaligned with the filter holes on the second filter screen 21 to change the size of the filter holes, thereby enabling the filtering and screening of rice pieces of different sizes, eliminating the need for secondary screening of the rice pieces, saving time and reducing the enterprise cost.

[0029] In addition, the terms "install", "set", "connect", and "socket" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there can be internal communication between two devices, components, or parts. Those of ordinary skill in the art can understand the specific meanings of the above terms in this application according to specific circumstances.
