AI Technical Summary

Technical Problem

In the construction of road and bridges, the incomplete crushing of stone leads to poor subsequent laying results, and the crushing process is inefficient, affecting the overall work efficiency.

Method used

A stone crushing and recycling device for road and bridge construction is designed, including a crushing box, a scraping mechanism, a lifting mechanism, a feeding mechanism, a screening mechanism and a return mechanism. Through impact crushing of the impact plate, scraping of the scraper, pushing up the top rod, leveling of the lever, particle size screening of the screening cylinder and re-coiling of the spiral shaft, the complete crushing and recycling of the stone is achieved.

Benefits of technology

This device can effectively prevent stone from sticking, ensure the crushing effect, and through multiple crushing and screening, ensure that the particle size of the stone meets the requirements, improving the overall crushing efficiency and working performance.

Abstract

The invention relates to the technical field of crushing devices, in particular to a road and bridge construction stone crushing and recycling device which comprises a crushing box, a cleaning and scraping mechanism, a jacking mechanism, a material stirring mechanism, a screening mechanism and a returning mechanism. According to the stone crushing device, the impact plate impacts downwards to impact and crush stones laid on the upper surface of the bottom plate, the two scraping plates are driven to slide in a state of keeping close to each other in the ascending process of the impact plate, the stones on the surface of the bottom plate are shoveled, scraped and loosened, the stones can be prevented from being adhered due to impact, and the crushing effect is guaranteed; stones which are crushed and fall off are subjected to granularity screening through the screening cylinder, it is guaranteed that the stones with the relatively large granularity are conveyed through the spiral shaft and are crushed again, the crushing effect on the stones is guaranteed, the ejector rod drives the ejector disc to slide up and down, the stones clamped in the bottom plate are ejected out, and the crushing efficiency is improved. And a stone pile on the surface of the bottom plate is leveled through a driving lever, so that normal crushing and discharging work is ensured, and the impact crushing effect on the stone is improved.
