[0027] Referring to Figures 1-6 , a rice crushing device includes a crushing box 1. Four conveyor rollers 6 are arranged at positions near both sides of the surface of the crushing box 1. Through holes are opened at positions near the middle of the surface and near the bottom of the surface of the crushing box 1. A conveyor belt 5 is sleeved on the surfaces of the four conveyor rollers 6. The upper and lower sides of the conveyor belt 5 respectively penetrate through the two through holes. Sieve holes are evenly opened on the surface of the conveyor belt 5. A crushing mechanism is arranged inside the crushing box 1. A fixing rod 13 is fixedly installed inside the crushing box 1. An auxiliary mechanism for assisting in screening the crushed rice is arranged on the surface of the fixing rod 13. A first motor 7 for driving the conveyor rollers 6 to rotate is fixedly installed on the side wall of the crushing box 1. During use, rice is poured into the opening at the top of the crushing box 1, and the rice is crushed by the crushing mechanism. The crushed rice will fall onto the conveyor belt 5, and screening is achieved by using the sieve holes on the conveyor belt 5. During the screening process, larger rice grains will be intercepted on the conveyor belt 5. At this time, the conveyor belt 5 can be directly rotated out by using the first motor 7, so that the rice grains intercepted on the conveyor belt 5 are conveyed out, and it is also convenient to clean the conveyor belt 5. Moreover, during the operation process, without affecting the screening effect, it is not necessary to stop the device, nor is it necessary to disassemble and clean the conveyor belt 5, so it is more convenient for actual use.

[0028] Furthermore, the crushing mechanism includes two crushing rollers 3. Shafts 10 are fixedly penetrated through the surfaces of the two crushing rollers 3. The two crushing rollers 3 are rotatably connected inside the crushing box 1 through the shafts 10, and the two shafts 10 both rotatably penetrate through the crushing box 1. A second motor 8 is fixedly installed on the side wall of the crushing box 1. The output shaft port of the second motor 8 is fixedly connected to the shaft 10. Transmission gears 19 are fixedly installed at positions on the surfaces of the two shafts 10 outside the crushing box 1. The two transmission gears 19 mesh with each other. During the use of the crushing mechanism, the second motor 8 is started, the second motor 8 drives the shaft 10 to rotate, the shaft 10 drives the crushing roller 3 to rotate, and the two crushing rollers 3 rotate synchronously and in opposite directions through the two transmission gears 19, so as to achieve the purpose of crushing the rice.

[0029] Furthermore, the auxiliary mechanism includes a transmission shaft 14 which is rotatably inserted into the interior of the fixed rod 13, and the transmission shaft 14 rotatably penetrates through the crushing box 1. A connecting shaft 16 is rotatably inserted into the central position at the bottom of the fixed rod 13. A dial rod 15 is fixedly installed at the bottom end of the connecting shaft 16. A first bevel gear 17 is fixedly installed on the surface of the connecting shaft 16 at the position inside the fixed rod 13. A second bevel gear 18 is fixedly installed at the port of the transmission shaft 14 inside the fixed rod 13. The first bevel gear 17 and the second bevel gear 18 are meshed. During the use of the auxiliary mechanism, the transmission shaft 14 is rotated. The transmission shaft 14 drives the second bevel gear 18 to rotate. The second bevel gear 18 drives the first bevel gear 17 to rotate. The first bevel gear 17 drives the connecting shaft 16 to rotate. The connecting shaft 16 drives the dial rod 15 to rotate. Thus, the rice falling on the conveyor belt 5 is agitated by the dial rod 15, which helps the rice to quickly pass through the sieve holes on the conveyor belt 5 and avoids the phenomenon that the conveyor belt 5 cannot be quickly screened due to rice accumulation. The top of the fixed rod 13 adopts a triangular structure, so that when the rice falls between the two crushing rollers 3, it can fall on both sides of the fixed rod 13 respectively, further reducing rice accumulation.

[0030] Furthermore, first turntables 9 are fixedly installed on the surfaces of the rotating shaft 10 and the transmission shaft 14. The two first turntables 9 are connected by belt drive. When the rotating shaft 10 rotates, it will drive the first turntable 9 to rotate. The two first turntables 9 rotate synchronously through the belt, thereby realizing the rotation of the transmission shaft 14.

[0031] Furthermore, a cleaning roller 11 is arranged at a position near the bottom inside the crushing box 1. Brush hairs are arranged on the surface of the cleaning roller 11. A power shaft 20 is fixedly penetrated through the surface of the cleaning roller 11. The power shaft 20 rotatably penetrates through the crushing box 1. Second turntables 12 are fixedly installed on the surfaces of the power shaft 20 and the transmission shaft 14. The two second turntables 12 are connected by belt drive. When the transmission shaft 14 rotates, it will drive the second turntable 12 to rotate. The two second turntables 12 rotate synchronously through the belt, thereby driving the power shaft 20 to rotate. The power shaft 20 rotates by using the cleaning roller 11 on its surface, and the brush hairs on the surface of the cleaning roller 11 are used to clean the conveyor belt 5, reducing the situation where rice grains are stuck in the sieve holes of the conveyor belt 5.

[0032] Furthermore, a through hole is formed in the front side wall of the crushing box 1. A discharge plate 2 is fixedly installed on the inner wall of the crushing box 1. The discharge plate 2 is inclined and is located inside the through hole. The discharge plate 2 is located between the upper and lower sides of the conveyor belt 5. Two guide plates 4 are fixedly installed at a position near the top inside the crushing box 1. By providing the discharge plate 2, the rice directly falls on the discharge plate 2 after screening and slides out of the crushing box 1 by using the discharge plate 2. By providing the guide plates 4, the rice can be located between the two crushing rollers 3 after feeding.

[0033] In summary, during use, rice is poured into the crushing box 1 from the opening at the top. The rice is crushed by the crushing mechanism. The crushed rice will fall onto the conveyor belt 5, and screening is achieved by using the sieve holes on the conveyor belt 5. During the screening process, larger rice grains will be intercepted on the conveyor belt 5. At this time, the conveyor belt 5 can be directly rotated out by the first motor 7, so that the intercepted rice grains on the conveyor belt 5 are conveyed out. At the same time, it is also convenient to clean the conveyor belt 5. Moreover, during the operation process, without affecting the screening effect, the device does not need to be shut down, and the conveyor belt 5 does not need to be disassembled and cleaned. Therefore, it is more convenient for actual use. During the use of the crushing mechanism, the second motor 8 is started. The second motor 8 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the crushing rollers 3 to rotate. The two crushing rollers 3 rotate synchronously and reversely through the two transmission gears 19, so as to achieve the purpose of crushing the rice. During the use of the auxiliary mechanism, the transmission shaft 14 is rotated. The transmission shaft 14 drives the second bevel gear 18 to rotate. The second bevel gear 18 drives the first bevel gear 17 to rotate. The first bevel gear 17 drives the connecting shaft 16 to rotate. The connecting shaft 16 drives the lever 15 to rotate. Thus, the rice falling on the conveyor belt 5 is agitated by the lever 15, which helps the rice to quickly pass through the sieve holes on the conveyor belt 5 and avoid the phenomenon that the conveyor belt 5 cannot be quickly screened due to rice accumulation. The top of the fixed rod 13 adopts a triangular structure, so that when the rice falls between the two crushing rollers 3, it can fall on both sides of the fixed rod 13 respectively, further reducing rice accumulation. When the rotating shaft 10 rotates, it will drive the first turntable 9 to rotate. The two first turntables 9 rotate synchronously through the belt, so as to achieve the rotation of the transmission shaft 14. When the transmission shaft 14 rotates, it will drive the second turntable 12 to rotate. The two second turntables 12 rotate synchronously through the belt, so as to drive the power shaft 20 to rotate. The power shaft 20 rotates by using the cleaning roller 11 on its surface. The brush hairs on the surface of the cleaning roller 11 are used to clean the conveyor belt 5, reducing the situation that rice grains are stuck in the sieve holes of the conveyor belt 5. By setting the discharge plate 2, after the rice is screened, it directly falls on the discharge plate 2 and slides out of the crushing box 1 through the discharge plate 2. By setting the guide plate 4, the rice can be located between the two crushing rollers 3 after feeding.
