[0031] Working principle:

[0032] Step one: when the user starts the device, the raw materials are poured into the first connecting shell 4 from the first material inlet 10 at the top of the first top cover 9, the raw materials fall on the surface of the first screen 8, the high-frequency vibrator body 7 vibrates the first screen 8 through the vibration rod, so that the raw materials in the first screen 8 fall into the lower layer of the first screen 8 for further screening, the concave design of the first screen 8 can concentrate the raw materials in the middle, reducing the possibility of screen blockage, and finally the screened raw materials fall into the first material box 2 through the first shell 1, if it is necessary to replace the mesh number of the first screen 8 or clean it, the user can rotate the first clamp block 6 to the two sides, so that one end of it is separated from the inner wall of the first limiting block 3, then remove the first top cover 9 and take out the first connecting shell 4 for maintenance or replacement, and increase the number of layers of the first connecting shell 4.

[0033] Step two: when the user inserts one end of the first clamp block 6 into the inner wall of the first limiting block 3, the first slide buckle 12 is pushed to slide along the inner wall of the first sliding groove 11, so as to limit the movement space of the first clamp block 6 and prevent it from expanding to the two sides, in the operation process, the first slide buckle 12 moves along the surface of the first sliding rod 13 in the first sliding groove 11, ensuring that its movement trajectory is stable and does not deviate, when the user moves the first slide buckle 12, the first spring 14 is compressed, and when it is necessary to reset the first slide buckle 12 to restrict the first clamp block 6 on both sides again, only need to loosen the first slide buckle 12, the first spring 14 will release the elastic force to push the first slide buckle 12 back to the original position.

[0034] Step three, after the user pours the raw material into the first hopper 10, the raw material will be blocked by the first regulating valve page 16 and temporarily cached, the user adjusts the pouring weight of the raw material through the first control panel 17 on one side of the first hopper 10, when the specified weight is reached, turn the first flip cover 18 and the first hopper 10 closed, the first sealing gasket 19 makes the raw material in the first hopper 10 not leak out, operate the first control panel 17 to drive the first motor 15 to rotate the first regulating valve page 16, adjust its angle, so that the raw material enters the equipment according to the predetermined feeding amount and speed, in the screening process, the larger particles in the raw material are first crushed by the first crushing roller 20 to the size suitable for screening, and finally the screened raw material falls on the surface of the second screen 21, the second motor 22 drives the first cleaning brush 23 to brush the raw material, the bristles on the inner wall of the first cleaning brush 23 make the raw material fall evenly and stably through the leakage hole of the second screen 21 and fall into the first material box 2, the accurate brushing force and frequency of the second motor 22 effectively prevent the leakage hole from being blocked and the raw material from accumulating.
