The rice husk fragments in the rice entering the box body 1 are blown away by the blower 11 and discharged through the discharge channel 3. A material guide channel 12 is provided inside the box body 1 to concentrate the rice onto the screening net 17 to prevent it from falling from the gap. An anti-blocking component 5 is provided on the side of the box body 1. The anti-blocking component 5 consists of an installation box 501, an electric push rod 502, a connecting rod 503 and an air nozzle 504. An electric push rod 502 is provided inside the installation box 501, and a connecting rod 503 is provided at the end of the electric push rod 502. An air nozzle 504 is provided on the surface of the connecting rod 503. The electric push rod 502 is controlled by the controller 9 to push the connecting rod 503, thereby controlling the air nozzle 504 to blow air under the screening net 17 to clear the blockage.

[0029] A spring damper 2 is provided inside the box body 1, and a vibration motor 14 is provided inside the box body 1. Support plates 15 are provided at the ends of the spring damper 2 and the vibration motor 14. The vibration motor 14 provides a power source and an exciting force, and transmits the vibration to the rice through the support plate 15, the mounting frame 16 and the screening net 17 to realize the screening process, while the spring damper 2 plays the role of supporting, buffering and stabilizing the vibration to ensure the smooth progress of the screening process. A mounting frame 16 is provided on the surface of the support plate 15. There is a vibration space between the mounting frame 16 and the box body 1. A discharge port 7 is provided on the side of the box body 1, and a discharge plate 8 is provided on the side of the mounting frame 16. There is a gap between the discharge port 7 and the discharge plate 8 to facilitate discharge. The plate 8 has space to move when vibrating, and large particles of impurities such as stones are discharged through the top discharge plate 8, the second discharge plate 8 discharges rice, and the third discharge plate 8 discharges smaller particles of impurities. A connecting column 19 is provided on the surface of the mounting frame 16, and the two mounting frames 16 are connected by the connecting column 19. The screening nets 17 of each mounting frame 16 are connected by the connecting column 19. A screening net 17 is provided inside the mounting frame 16, and the screening net 17 is installed through a chute opened on the side of the mounting frame 16. The screening net 17 at the top filters larger particles, and the second screening net 17 from top to bottom filters smaller particles. The screening net 17 at the bottom does not filter, and directly vibrates and discharges the filtered small particles.

[0030] The side of the box body 1 is provided with a movable opening 13, and the surface of the movable opening 13 is hinged with a protective door 4. The protective door 4 is opened and the screening net 17 is disassembled and replaced through the movable opening 13. The side of the screening net 17 is provided with a movable groove 18. The setting of the movable groove 18 facilitates the disassembly of the screening net 17. The interior of the screening net 17 is provided with a movable groove 22. The interior of the movable groove 22 is provided with a fixing assembly 6. The fixing assembly 6 consists of a buffer spring 601, a movable rod 602 and a fixed block 603. The end of the buffer spring 601 is provided with a movable rod 602, and the surface of the movable rod 602 is provided with a fixed block 603, the movement of the fixed block 603 is controlled by the movable rod 602, and under the action of the buffer spring 601, the fixed block 603 is conveniently fixed into the fixed groove 21. The interior of the mounting frame 16 is provided with a fixed groove 21. The shape and position of the fixed block 603 are adapted to the fixed groove 21, which facilitates the fixing of the mounting frame 16 and the screening net 17. A controller 9 is provided on the side of the box body 1, and the operation of the entire device is controlled by the controller 9. An observation window 10 is provided on the side of the box body 1, and the amount of rice discharged during the rice separation process is observed through the observation window 10 to avoid clogging of the screening net 17.

[0031] The rice enters the box body 1 through the feed channel 20, and the blower 11 is turned on by the controller 9 to blow away the rice husk fragments in the rice and discharge them through the discharge channel 3. The vibration motor 14 is turned on to provide power source and exciting force, and the vibration is transmitted to the rice through the support plate 15, the mounting frame 16 and the screening net 17 to realize the screening process. At the same time, the spring damper 2 plays the role of supporting, buffering and stabilizing the vibration to ensure the smooth progress of the screening process. Then the rice enters the top screening net 17 through the material guide channel 12, and large particles of impurities such as stones in the rice are screened out and discharged through the top discharge plate 8. The screened rice falls on the second screening net 17, and smaller particles of impurities therein are screened. The smaller particles of impurities fall on the bottom screening net 17. The cleanly screened rice is discharged through the middle discharge plate 8, and the smaller particles of impurities are discharged through the bottom discharge plate 8.

[0032] When it is necessary to replace the screening mesh 17 with a different screening size, the protective door 4 is opened, the movable rod 602 is pressed toward the middle, the buffer spring 601 is squeezed, and the fixed block 603 is moved out of the fixed slot 21, thereby sliding the screening mesh 17 out of the mounting frame 16, and the newly replaced screening mesh 17 is inserted into the mounting slot, and the movable rod 602 is released. Under the reaction force of the buffer spring 601, the fixed block 603 is moved toward the fixed slot 21, thereby quickly replacing the screening mesh 17 and the mounting frame 16. When the personnel observes that the amount of material discharged during the rice separation process is significantly reduced through the observation window 10, the controller 9 controls the electric push rod 502 to push the connecting rod 503, and at the same time opens the air nozzle 504, and blows air to the screening mesh 17 through the air nozzle 504 to blow away the impurities blocked on the screening mesh 17 and keep the screening of the screening mesh 17 unobstructed. Specific embodiment two:

[0034] On the premise of meeting the above structure, a laser counter can be installed in the box body 1 to monitor the discharge amount of rice impurity separation in real time through the laser counter. When the discharge amount is abnormal, the signal is transmitted to the controller 9, and the controller 9 controls the electric push rod 502 and the air nozzle 504 to open, thereby realizing automatic blockage clearing. There is no need for personnel to observe the separation process of rice impurities all the time, which saves manpower.

[0035] In summary:

[0036] 1. The mounting frame 16, the screening mesh 17, the fixing assembly 6 and the fixing slot 21 are used. When the screening mesh 17 of a different screening size needs to be replaced, the protective door 4 is opened, the movable rod 602 is pressed toward the center, the buffer spring 601 is squeezed, and the fixing block 603 is moved out of the fixing slot 21, thereby sliding the screening mesh 17 out of the mounting frame 16, and inserting the newly replaced screening mesh 17 into the mounting slot. The movable rod 602 is released, and the fixing block 603 is moved into the fixing slot 21 under the reaction force of the buffer spring 601, thereby quickly replacing the screening mesh 17 and the mounting frame 16, so that they are adapted to the sizes required for different screening, thereby improving the practicality of the screening device.

[0037] 2. The anti-blocking component 5 and the observation window 10 are used to enable personnel to observe the amount of rice being discharged during the separation process through the observation window 10. When the amount of rice being discharged is significantly reduced, the controller 9 controls the electric push rod 502 to push the connecting rod 503, and at the same time opens the air nozzle 504 to blow air onto the screening net 17 through the air nozzle 504 to blow away impurities blocked on the screening net 17, thereby keeping the screening of the screening net 17 unobstructed and ensuring the normal separation of rice impurities.
