AI Technical Summary

Technical Problem

When the existing aggregate screening mechanism of concrete mixing stations is used, a single vibrating motor may cause aggregate accumulation and reduce screening efficiency.

Method used

A concrete mixing plant aggregate screening mechanism is designed, using two sets of vibrating motors and two sets of drive motors. The drive shaft and the gear-deficient gear are driven to rotate through disguised bevel gears, so as to realize the left and right movement of the screening assembly, improve screening efficiency and reduce aggregate accumulation.

Benefits of technology

By simultaneously starting the vibration motor and driving the motor, efficient screening of aggregates is achieved, reducing aggregate accumulation and blockage problems, and improving overall screening efficiency.

Abstract

The utility model discloses a concrete mixing plant aggregate screening mechanism which comprises an outer cabinet assembly, a screening assembly is movably erected above the outer cabinet assembly, the outer cabinet assembly comprises an outer cabinet body, driving tooth surfaces are fixedly connected to the middles of the two ends of the upper portion of the outer cabinet body, and sliding cushion blocks are fixedly connected to the outer sides of the two ends of the upper portion of the outer cabinet body. The screening assembly comprises a screening movable cabinet, sliding butt straps are fixedly connected to the two sides of the screening movable cabinet, a rotating shaft connecting base is fixedly connected to one end of the middle of the upper portion of each sliding butt strap, and a driving rotating shaft is rotationally connected to one end of each rotating shaft connecting base. The vibrating motor and the two driving motors are started at the same time, the two driving rotating shafts and the tooth-missing gears are driven to rotate through the phase-changing bevel gear, the two tooth-missing gears are sequentially meshed with the lower driving tooth face and can drive the screening assembly to move in a left-right reciprocating mode, and therefore screening work can be more efficiently carried out; and left-right movement can drive aggregate to shake, so that the problem of accumulation and blockage is solved.
