Vibrating screen angle regulating mechanism with limit function

Abstract

The invention discloses a vibrating screen angle regulating mechanism with a limit function. The mechanism comprises a base, a screen net support, a screen net, an electric push rod and driving motor. A baffle is arranged at one end of the base. A supporting frame is arranged at the other end of the base. A fixing column is arranged at the end, close to the baffle, of the base. A movable block is arranged on the upper portion of the fixing column. One end of the screen net support is mounted on the movable block through a rotary shaft. A cross beam is arranged at the other end of the screen net support and arranged on the upper portion of an arc-shaped plate. A hoisting plate is arranged on a cross beam at the top of the supporting frame. A lifting lug is arranged at the top of the electric push rod and mounted on the hoisting plate through a hinge pin. The push rod end portion of the electric push plate is connected with the arc-shaped plate through a knuckle bearing. The electric push rod is connected with the driving motor. A magneto sensor is mounted on the electric push rod. On the whole, the vibrating screen angle regulating mechanism can be used for fast changing the inclination angle of the screen net, and slurry wasting caused when slurry splashes out of the screen net is avoided; and meanwhile, the limit function is achieved.

Description

technical field [0001] The invention belongs to the technical field of vibrating screens, in particular to an angle adjustment mechanism with a limit function for vibrating screens. Background technique [0002] Drilling fluid shale shaker is the first-level solid control equipment used in the drilling mud purification system, and is used to remove larger solid particles in the drilling fluid returned from the bottom of the well. In drilling operations, vibrating screens are indispensable in the process. The vibrating screen works by using the vibration generated by the exciting motor. By changing the curve shape of the motion track of the screen surface and changing the motion track of the material on the screen surface, the screening of materials is realized. Generally speaking, the material is thrown up on the screen surface and moves forward in a straight line, so as to achieve the purpose of screening and grading the material. In the prior art, most of the vibrating s...

AI Technical Summary

Problems solved by technology

In the prior art, most of the vibrating screens vibrate in the horizontal, vertical, and inclined directions of the motor. The horizontal angle of the screen is fixed and cannot be adjusted. It cannot meet the mud screening under different working conditions, thus affecting the quality of the mud. Purification effect
