Problems solved by technology

[0003] Vibrating screens need to be improved in different situations. When coal is screened underground, it is necessary to reciprocate the newly mined coal mine in one direction, that is, to keep the screen body reciprocating along a straight line to achieve the purpose of screening. Vibrating screens are prone to damage after long-term use. In the coal industry, speeding up the maintenance and installation of vibrating screens is one of the key issues to improve the screening process.

Abstract

The invention discloses a vibrating screen. The vibrating screen comprises a screen body, buckles, a mounting seat and a support. The support is detachably mounted on an external fixed surface. The mounting seat is mounted on the support through elastic connecting structures, so that the mounting seat does reciprocating motion when bearing an external regular vibration source. The screen body is slidably mounted in a groove formed in the top of the mounting seat. The mounting seat is slidably connected with the screen body through the buckles. Each buckle comprises a connecting part, a handle,a rotary shaft, a mounting block, a spring I and a lock nut. The mounting blocks are fixedly mounted on the side faces of the mounting seat and provided with guide grooves penetrating through the upper and lower end faces. The side face of each handle is provided with a cavity. Each mounting block is loosely contained in one end of corresponding cavity, and the end is provided with a bolt which is arranged in the corresponding guide groove. The vibrating screen is simple in structure and more suitable for underground coal screening.

Description

technical field [0001] The invention relates to the technical field of vibrating devices, in particular to a vibrating screen. Background technique [0002] The previous vibrating screens work 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.
