[0026] Refer to Figures 1-5, A rice dandruff removing device for rice processing, including a mounting frame 1. Inside the mounting frame 1, there is a conveyor belt 6. On the surface of the mounting frame 1 at the position above the conveyor belt 6, a storage bin 2 is fixedly installed. The top of the storage bin 2 is communicated with a feed inlet 3. A control mechanism for controlling the discharge is arranged on the side wall of the storage bin 2. An auxiliary mechanism for leveling the rice is arranged on the surface of the mounting frame 1. At the bottom of the mounting frame 1, there is a filter plate 15. Between the filter plate 15 and the mounting frame 1, there is a spring 16. The two ends of the spring 16 are respectively fixedly connected to the mounting frame 1 and the filter plate 15. On the surface of the mounting frame 1 at the position above the filter plate 15, there is a rolling plate 10. A vibration mechanism for driving the rolling plate 10 to perform reciprocating up and down vibrations is arranged on the surface of the mounting frame 1. The top of the filter plate 15 is set as an inclined plane, and the bottom of the rolling plate 10 is parallel to the filter plate 15. Dust collectors 17 are fixedly installed on both sides of the mounting frame 1. Dust suction pipes 18 are fixedly installed on both sides of the filter plate 15. The dust collectors 17 are communicated with the dust suction pipes 18. When in use, the rice is put into the storage bin 2 from the feed inlet 3. Using the control mechanism, the amount of rice discharged is controlled, so that the rice falls onto the surface of the conveyor belt 6. The conveyor belt 6 carries the rice forward. When moving, using the leveling mechanism, the piled-up rice is leveled on the conveyor belt 6, and then conveyed to the surface of the filter plate 15. The vibration mechanism is started, and the vibration mechanism drives the rolling plate 10 to vibrate up and down, so that the rolling plate 10 pats the rice on the surface of the filter plate 15, enabling the rice husks in the rice to be separated from the rice. When the rolling plate 10 presses downwards, the spring 16 at the bottom of the filter plate 15 contracts. When the rolling plate 10 moves upwards, the spring 16 automatically expands, driving the rice on the surface of the filter plate 15 to rise. At this time, both the rice and the rice husks are in a suspended state. At this time, the dust collectors 17 and the dust suction pipes 18 on both sides of the mounting frame 1 can take the opportunity to adsorb the rice husk debris, so that the rice husks and other debris in the rice are removed. At the same time, the filter plate 15 can also screen the rice, so that the impurities that are not easily adsorbed fall from the mesh holes on the surface of the filter plate 15, further improving the dandruff removal effect. The top of the filter plate 15 is set as an inclined plane, so that the rice can gradually slide down during the vibration process, and the rice after the dandruff removal is completed will automatically slide out of the filter plate 15, which is convenient for actual use and improves the use convenience.
[0027] Further, the position of the conveyor belt 6 is higher than the position of the filter plate 15. By setting the height difference between the conveyor belt 6 and the filter plate 15, it is convenient for the rice on the conveyor belt 6 to directly fall onto the filter plate 15.
[0028] Further, the control mechanism includes a plugging plate 4. The plugging plate 4 is slidably inserted into the bottom of the storage bin 2. A screw rod 5 is rotatably inserted into the side wall of the storage bin 2. The screw rod 5 threadedly penetrates the plugging plate 4. When the control mechanism is in use, the screw rod 5 is used to drive the plugging plate 4 to move horizontally, thereby controlling the size of the discharge port of the storage bin 2, facilitating the control of the rice falling amount and being convenient for actual use.
[0029] Further, the vibration mechanism includes a limiting rod 14 and a motor 11. The limiting rod 14 is fixedly installed on the top of the rolling plate 10. The limiting rod 14 slidably penetrates through the mounting frame 1. The motor 11 is fixedly installed on the top wall of the mounting frame 1. A turntable 12 is fixedly installed at the output end port of the motor 11. A rotating shaft is rotatably connected to a position near the edge of the surface of the turntable 12. A connecting rod 13 is rotatably connected to the surface of the rotating shaft. The port of the connecting rod 13 is rotatably connected to the rolling plate 10. During the use of the vibration mechanism, the provided limiting rod 14 can limit the rolling plate 10 to only move in the vertical direction. Start the motor 11, and the motor 11 drives the turntable 12 to rotate. The turntable 12 drives the connecting rod 13 to move. The connecting rod 13 drives the rolling plate 10 to perform reciprocating movement in the up and down directions, so as to realize the function of using the rolling plate 10 to pat the rice on the filter plate 15.
[0030] Further, the auxiliary mechanism includes a sliding frame 8. Two fixed rods 7 are fixedly installed on the surface of the mounting frame 1 relative to the top of the conveyor belt 6. The sliding frame 8 is slidably sleeved on the surfaces of the two fixed rods 7. A shifting rod is fixedly installed at the bottom of the sliding frame 8. A connecting rod 9 is fixedly installed on the side wall of the sliding frame 8. The rolling plate 10 is arranged in an "L" shape. A Z-shaped groove 19 is formed in the side wall of the rolling plate 10. The connecting rod 9 is slidably connected to the Z-shaped groove 19 to achieve a state where the up and down vibration of the rolling plate 10 drives the connecting rod 9 to swing left and right. During the use of the auxiliary mechanism, the sliding frame 8 can only slide left and right on the two fixed rods 7. When the rolling plate 10 moves up and down, the Z-shaped groove 19 on the surface can be used to drive the connecting rod 9 and the sliding frame 8 to slide left and right, so that the sliding frame 8 drives the shifting rod to flatten the rice on the surface of the conveyor belt 6, which is convenient for the rolling plate 10 to roll and remove the husk of the rice, facilitating actual use.
[0031] Further, the two dust suction pipes 18 are located on both sides of the rolling plate 10. The dust suction pipes 18 are located on both sides of the rolling plate 10 and do not affect the up and down movement of the rolling plate 10, which is convenient for adsorbing the rice husks.
[0032] In summary, when in use, put rice into the storage bin 2 from the feed inlet 3, use the control mechanism to control the amount of rice discharged, so that the rice falls onto the surface of the conveyor belt 6. The conveyor belt 6 carries the rice forward. When moving, use the leveling mechanism to level the piled-up rice on the conveyor belt 6, and then convey it to the surface of the filter plate 15. Start the vibration mechanism, and use the vibration mechanism to drive the rolling plate 10 to vibrate up and down, so that the rolling plate 10 pats the rice on the surface of the filter plate 15, enabling the rice husks in the rice to be separated from the rice. When the rolling plate 10 presses downwards, the bottom spring 16 of the filter plate 15 contracts. When the rolling plate 10 moves upwards, the spring 16 automatically expands, driving the rice on the surface of the filter plate 15 to rise. At this time, both the rice and the rice husks are in a suspended state. At this time, the dust collectors 17 and the dust suction pipes 18 on both sides of the mounting frame 1 can adsorb the rice husk debris, removing the rice husk debris and other debris in the rice. At the same time, the filter plate 15 can also screen the rice, allowing the impurities that are not easily adsorbed to fall through the mesh holes on the surface of the filter plate 15, further improving the debriding effect. The top of the filter plate 15 is set as an inclined surface, so that the rice can gradually slide down during the vibration process, enabling the debrided rice to automatically slide out of the filter plate 15, facilitating actual use and improving the convenience of use. By setting the height difference between the conveyor belt 6 and the filter plate 15, it is convenient for the rice on the conveyor belt 6 to directly fall onto the filter plate 15. When in use, the control mechanism uses the screw 5 to drive the plugging plate 4 to move horizontally, thereby controlling the size of the discharge port of the storage bin 2 and facilitating the control of the amount of rice falling, which is convenient for actual use. During use, the limiting rod 14 provided in the vibration mechanism can limit the rolling plate 10 to only move in the vertical direction. Start the motor 11, the motor 11 drives the turntable 12 to rotate, the turntable 12 drives the connecting rod 13 to move, and the connecting rod 13 drives the rolling plate 10 to move reciprocally in the up and down directions, thereby realizing the function of using the rolling plate 10 to pat the rice on the filter plate 15. When in use, the sliding frame 8 can only slide left and right on the two fixed rods 7. When the rolling plate 10 moves up and down, the Z-shaped groove 19 on the surface can be used to drive the connecting rod 9 and the sliding frame 8 to slide left and right, and then the sliding frame 8 drives the lever to level the rice on the surface of the conveyor belt 6, facilitating the rolling plate 10 to roll and remove the husks of the rice, which is convenient for actual use. The dust suction pipes 18 are located on both sides of the rolling plate 10 and do not affect the up and down movement of the rolling plate 10, facilitating the adsorption of the rice husks.
