[0042] Working principle:

[0043] When the present invention is in use, through the setting of the feeding mechanism 3, the adjusting motor 303 controls the adjusting shaft to drive the adjusting plate 304 to rotate, thereby changing the angle between the adjusting plate 304 and the inner wall of the feeding box 301, and then controlling the feeding amount and feeding speed of the material, so as to achieve the best filtering effect.

[0044] By setting the first filtering mechanism 4, the material enters the filter box 1 through the feeding mechanism 3, falls on the filter roller 401, and enters the filter box 1 under the action of the plurality of filter holes 402, and thus the filter holes 402 below fall into the receiving box 2, completing the preliminary filtration of the material, and the driving motor 408 drives the transmission gear 409 to rotate, thereby driving the rotating gear 407 meshing with it to rotate, and the rotating gear 407 drives the filter roller 401 to rotate, so that the plurality of filter holes 402 on the filter roller 401 filter the material in turn, solving the problem that the filter holes 402 are blocked by impurities.

In addition, when the filter roller 401 rotates, a relative rotation occurs between the filter roller 401 and the fixed shaft 412, so that the first vibration column 413 continuously collides with the second vibration column 414, and is reset under the action of the telescopic component, thereby realizing repeated collisions between the first vibration column 413 and the second vibration column 414, driving the filter roller 401 to vibrate, and improving the filtering efficiency of the filter hole 402.

[0045] By setting the second filtering mechanism 5, the material falls onto the filter plate 501 under the filtration of the first filtering mechanism 4. Since the aperture of the filter is smaller than the aperture of the filter hole 402, the impurities mixed in the material can be further filtered, and the filtering effect is better. In addition, the output shaft is controlled by rotating the motor 503 to drive the eccentric wheel 504 to rotate, and the reset spring 502 drives the filter plate 501 to vibrate up and down repeatedly, thereby improving the filtering effect on the material.
