An eccentric block 6 is provided inside the end cover 5; an adjustable eccentric block 6 is sleeved on the motor rotating shaft 7 extending out of both end faces of the casing 1, and the tail end is rotationally connected to the center of the end cover 5 through a plug; a filter housing 8 is provided outside the end cover 5, and an air automatic adjustment mechanism 9 is provided inside the filter housing 8; there are two groups of the air automatic adjustment mechanism 9, which are respectively attached to the inner wall of the filter housing 8 and communicated with the filter holes 10 on the surface of the filter housing 8. One side is buckled inside the filter housing 8, and the other side is buckled on the end cover 5 and communicated with the inside of the end cover 5.

[0018] Specifically, the eccentric block 6 adopts a stepless speed regulation design method. By adjusting the included angle between the inner and outer offsets, the exciting force and amplitude can be steplessly adjusted to meet the requirements of various working conditions; the motor frequency is designed as a wide frequency through the circuit in the junction box 3 to achieve a large vibration frequency range. The vibration frequency of an ordinary vibrator is fixed, generally equal to the power frequency, while the vibration frequency of this vibration motor can be adjusted by adjusting the rotational speed, and the vibration frequency and amplitude can be arbitrarily selected according to different uses; the upper and lower eccentric 6 blocks extending from the vibration motor rotating shaft 7 are designed separately. Through the mass difference between the two, a longitudinal bending moment is generated on the sieve body, forming a bumpy movement with a large vibration angle at the front end and a small vibration angle at the tail end of the sieve body, so as to achieve an excellent screening effect.

[0021] Specifically, the fixed cylinder 14 is a hollow cylinder, the outer diameter matches the inner diameter of the filter housing 8, the inner diameter is larger than the plug of the rotating shaft 7, and it is integrally connected to the end cap.

[0025] In the specific operation process, the filter housing 8 is fixed on both sides of the end cover 2 by rotating the handle 19.

The bimetallic strip 17 at the bottom of the fluid passage 15 bends according to the pressure difference, and the communication air chamber 16 is communicated with the outside through the filter holes 10, so as to adjust the external air pressure and the internal air pressure, so that the internal air pressure of the vibration motor is adjusted and the internal and external air pressure difference is adjusted.

Those of ordinary skill in the art understand that many modifications, changes or equivalents can be made without departing from the spirit and scope defined by the appended claims, but all of them will fall within the protection scope of the present utility model.
