Self-feeding type stone crushing and screening device

Abstract

The invention discloses a self-feeding type stone crushing and screening device, which comprises a base, a slide rail is arranged on the top of the base, and a rack and a crushing box are respectively slidably connected to the top of the slide rail through a slider; the crushing box is provided with a fixed extrusion plate , a number of sieve holes are evenly arranged on the fixed extrusion plate; support plates are arranged on the left and right sides of the top of the base, and a top plate is arranged on the top of the support plate, and the bottom of the top plate is connected to the second pulley through the rotation of the bracket, and the front surface of the second pulley is fixedly connected to a The driven gear, the bottom of the top plate is also fixedly connected with a deceleration motor through a bracket, the motor shaft at the front end of the deceleration motor is equipped with a driving gear, the top of the front end of the driven gear and the driving gear are all provided with a third pin shaft, and the third pin shaft is rotatably connected with an extrusion pin. The compression rod is hinged with a lifting extrusion plate at the bottom end of the extrusion rod. In the present invention, the lifting extrusion plate moves up and down through the meshing and rotation of the gears to extrude and pulverize the stone material, and the pulverization efficiency is high; the pulverized stones are screened through the sieve holes on the fixed extrusion plate.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a self-feeding stone crushing and screening device. Background technique [0002] Stones are inseparable from the raw materials in the construction process of buildings. The quality of stones directly affects the quality of buildings. After mining, stones vary in size and shape. Some stones are too large to be used for construction directly. Therefore, stones need to be crushed to It is convenient to use stones. [0003] The ordinary crushing device needs to manually control the feeding during crushing, which is cumbersome; some stones are not crushed during the crushing process, and the crushing is not sufficient, resulting in a low crushing efficiency; and the stones are not screened after crushing, and the volume of some stones is still small. Meet the quality requirements. Contents of the invention [0004] The object of the present invention is to provide ...
