Stone crushing device for house building engineering

Abstract

The invention discloses a stone crushing device for house building engineering. The stone crushing device comprises a crushing bin, a discharging opening is formed in the middle position of the bottom of the crushing bin, impact assemblies are symmetrically arranged on the two sides of the bottom of the crushing bin, a second servo motor is arranged at the middle position of the bottom of one end of the front face of the crushing bin, and a second rotating rod extending into the crushing bin is arranged at the output end of the second servo motor. Through mutual cooperation of the second servo motor, the second rotating rod, a screening net plate, connecting rods, tooth blocks, half gears, poke rods, hinged rods, impact balls, fixing blocks, sliding rods, mounting grooves, first springs, arc-shaped sliding rods and second springs, the discharging opening can be continuously impacted, so that the discharging opening is prevented from being blocked, the discharging speed of the discharging opening is increased, an operator can do manual dredging work without the help of other dredging tools, the working steps of the operator are reduced, and the working efficiency and operation convenience of the device are improved.

Description

technical field [0001] The invention relates to the technical field of house construction engineering, in particular to a stone crushing device for house construction engineering. Background technique [0002] In housing construction projects, it is often necessary to use crushed stones as building materials, such as using crushed stones to make concrete, etc., and crushed stones are usually obtained by putting larger stones into a crushing stone device for crushing, so crushed stones Stone fixtures are common fixtures in the house building industry; [0003] The internal structure of the existing crushing device is relatively simple, and most of them can only crush the stones. When more crushed stones are discharged, it will not only slow down the discharge speed, but also block the position of the discharge port. The operator uses other dredging tools to perform manual dredging work, which increases the waiting time and operation steps of the operator, thereby reducing th...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of crushing device for building construction, to solve the problem that the internal structure of the existing crushing device proposed in the above-mentioned background technology is relatively simple, and most of them can only crush stones, and when more crushed stones When discharging, it will not only slow down the discharge speed, but also block the position of the discharge port, and the operator needs to use other dredging tools to manually dredge the work, which increases the waiting time and operation steps of the operator, thereby reducing the broken material. The working efficiency of the stone device; most of the existing stone crushing devices are used to crush the stones uniformly, and the unified crushing work can increase the waiting time of the operator again, and at the same time cause the internal crushed stones to be of different sizes, reducing the The passing rate of crushed stones is reduced, but for larger crushed stones, the operator needs to manually put them into the crushed stone device for crushing, which again increases the tediousness of the operator's work and reduces the practicability of the crushed stone device. question
