Multi-stage building stone crushing device

Abstract

The invention discloses a multi-stage building stone crushing device, which comprises a base, support plates are arranged on the left and right sides of the base, a crushing box is fixedly arranged between the support plates through brackets, and an extrusion seat is fixedly arranged on the left side of the crushing box , the right side wall of the crushing box is provided with a hydraulic cylinder, the piston rod of the hydraulic cylinder is hinged with an extruding plate, and the top of the extruding plate is provided with a rectangular groove, and the rear side wall of the crushing box is provided with a second motor. The motor shaft at the front end of the motor passes through the rear side wall of the crushing box and is connected with a turntable. The front end of the turntable is fixed with a pin shaft. The pin shaft is located in a rectangular groove and cooperates with the rectangular groove. directly above the hopper. The invention drives the extrusion plate to move left and right through the rotation of the turntable to crush the stone. Every time the turntable rotates, the stone falls once, and the stone is gradually broken and becomes smaller, which is beneficial to the protection device. By controlling the length of the hydraulic cylinder piston rod, the crushing box can also be crushed The size of the final discharged stone is controlled.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a multi-stage construction stone crushing device. Background technique [0002] With the improvement of urbanization, new buildings are built every day. Buildings are inseparable from stone materials in the construction process, and some stone materials are too large to be directly used for construction. It is convenient to use stone materials. [0003] The general crushing device needs to control the feeding manually, which is not very convenient to use. When crushing, it will be crushed directly regardless of the size of the stone, which will cause a large load on the mechanical parts, and even cause direct damage to the device, which is not conducive to the maintenance of the device, and the crushing efficiency is not good. High, the stone cannot be screened during crushing, and there are still many stones that do not meet the requirements after crushing and cannot be us...

Problems solved by technology

[0003] The general crushing device needs to control the feeding manually, which is not very convenient to use. When crushing, it will be crushed directly regardless of the size of the stone, which will cause a large load on the mechanical parts, and even cause direct damage to the device, which is not conducive to the maintenance of the device, and the crushing efficiency is not good. High, the stones cannot be screened during crushing, and there are still many stones that do not meet the requirements after crushing and cannot be used directly, which will cause a waste of resources
