Problems solved by technology

The existing vibrating screen has the defects of uneven distribution, slow screening speed, weak excitation force, large vibration noise and high energy consumption
However, the vibration excitation mechanism adopted by the existing vibrating screen cannot be stopped when the vibration amount needs to be changed, and the eccentric mass block must be manually increased or decreased, which is cumbersome to use, does not have good continuity, and cannot Achieve the effect of real-time increase or decrease of mass blocks

Abstract

The invention discloses a vibration exciter used for an equal-thickness separating screen. The vibration exciter comprises an eccentric mechanism and a transmission mechanism. The eccentric mechanism comprises an eccentric wheel with a through hole, a torsional spring, pulleys and clamping teeth. The transmission mechanism comprises a vibration motor, a transmission shaft, a clamping head and a speed changer. The transmission shaft is connected with a rotating shaft of the vibration motor through the speed changer; the clamping head is vertically connected on the transmission shaft; the transmission shaft is sleeved with the eccentric wheel through the through hole; the pulleys are installed on the inner side wall of the through hole; the position, located at the through hole, of the eccentric wheel is connected with one end of the torsional spring, and the other end of the torsional spring is connected with the clamping teeth; and the eccentric wheel can slide in the axial direction of the transmission shaft. The eccentric wheel of the vibration exciter can join in operation under the working state, the impact on equipment is reduced, and the life of the mechanical equipment is prolonged. In addition, the clamping head and the clamping teeth of the structure are mutually matched to rapidly clamp the device, so that the vibration magnitude of the vibration exciter is effectively controlled.

Description

technical field [0001] The invention relates to an exciter used for equal-thickness sorting and screening, and belongs to the field of exciters. Background technique [0002] The vibrating screen works by using the reciprocating rotation vibration generated by the vibration of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce plane circular vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. Its vibration track is a complex space curve. The projection of the curve on the horizontal plane is a circle, while the projection on the vertical plane is an ellipse. The vibration amplitude can be changed by adjusting the excitation force of the upper and lower rotating weights. And adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the motion track of the screen surface and change the motion track of the material on the screen surface. The e...
