[0002] The multi-stage screening device for grain processing is a device specially used for grain particle size classification and impurity removal. It usually consists of multiple levels of screens or sieve holes, and the aperture of the screen gradually decreases. The grain passes through the device and enters the upper screen. As the device vibrates or moves, larger grain particles are blocked on the upper screen, while smaller grain particles pass through the screen and enter the next layer. This process will continue until the grain particles reach the required particle size.

If too much grain is put into the screening at one time, it may cause the working efficiency of the device to decrease, reducing the practicality of the device; at the same time, the existing grain multi-stage screening device has to screen a large amount of grain. After repeated use, some grain residues may accumulate. If they are not removed in time, the multi-stage screening effect will be affected, and the screening quality of the grain will be reduced.

[0029] The cleaning structure is installed on the inner wall of the fixed plate 8 and is used to clean the dust inside the device.
[0030] Furthermore, the sliding structure includes a sliding base 41 and a worm 46. The sliding base 41 is slidably connected to the sliding rail 14. A fixing column 45 is inserted on the upper surface of the sliding base 41. Figure 3 As shown, by setting a sliding structure, the device can reciprocate left and right, thereby improving the screening effect.
[0031] Furthermore, a worm 46 is inserted at the bottom end of the fixed block 3, and two groups of worms 46 are provided. The two groups of worms 46 are meshed and connected with a second worm wheel 44. Figure 3 As shown, this design enables the device to have two modes of movement, thereby improving the structural rationality and practicality of the device.
[0032] Further, a connecting rod 47 is fixedly connected to the center of the second worm gear 44, the upper end of the connecting rod 47 is connected to the first worm gear 43, and a supporting plate 42 is fixed to the middle position of the connecting rod 47. Figure 3 As shown, the stability of the structure is enhanced so that the device can operate effectively.
[0033] The further cleaning structure includes a screening box 5 and a cleaning rod 7. The screening box 5 is slidably connected to the sliding base 41. The upper surface of the screening box 5 is inserted with a discharge port 6. One side of the screening box 5 is inserted with a multi-level screen 10, and the multi-level screen 10 is provided with multiple groups. The back side of the screening box 5 is installed with a clamping plate 11, and the clamping plate 11 is provided with multiple groups. A vibration motor 12 is installed below the screening box 5.

[0034] Furthermore, the cleaning rods 7 are inserted into the inner wall of the fixing plate 8, and the cleaning rods 7 are arranged in multiple groups, and the diameters of the multiple groups of cleaning rods 7 match the heights of the clamping plates 11. Figure 5 As shown, the cleaning rod 7 can clean the multi-level screen 10, thereby improving the rationality of the device.
[0035] Working principle: pour the grains into the screening box 5 from the discharge port 6, turn on the servo motor 2 switch on the control panel 13, and the worm 46 starts to rotate. When one group of worms 46 rotates clockwise and the other group of worms 46 rotates counterclockwise, the two groups of worms 46 drive the second worm gear 44 to start rotating.

[0036] After screening, the multi-level screen 10 needs to be cleaned. The locking plate 11 is removed through the notch, the switch of the servo motor 2 is turned on, and the worm 46 starts to rotate. When the two groups of servo motors 2 move clockwise or counterclockwise at the same time, the combination of the second worm gear 44, the support plate 42, and the first worm gear 43 is locked between the two groups of worm gears 46 and remains stationary. The sliding track 14 slides along the sliding rod 9 with the sliding base 41. When the cleaning rod 7 completely enters the screening box 5, until the bottom of each multi-level screen 10, since the multi-level screen 10 is locked inside the screening box 5, at this time, the servo motor 2 is adjusted back to make the two groups of worm gears 46 rotate in different directions, and the sliding base 41 starts to move back and forth along the sliding track 14 to achieve a cleaning effect.
