Stone crushing device for civil engineering

Abstract

The invention discloses a stone crushing device for civil engineering. The device comprises a box body, a fixed plate, a treatment box, a screen, a guide plate, a driving motor, a belt wheel, a belt, a rotating shaft, a crushing rod, a shell, a partition plate, a shell, a crushing motor, a crushing roller, a splitter plate, an upper opening, a lower opening, a mounting base, a conveying roller, a connecting shaft, a conveying motor, a chain wheel, a chain, a filter screen, a discharging opening, supporting legs, a feeding pipe, a feeding hopper, a filter plate, a fixed pipe, a connecting pipe, an upper fan and an air inlet pipe. The crushing device comprises a lower fan, an air outlet pipe, a filter box, a crushing motor, a crushing roller and a gear. The stone crushing device has the beneficial effects that the stone crushing device is adopted for crushing stones, dust overflow is avoided, the air quality is improved, the stones can be subjected to multi-stage crushing, the stones can be screened after being crushed, secondary crushing treatment is facilitated, meanwhile, the uniformity of crushed stones can be guaranteed, the stones are sequentially conveyed at the bottom of the box body, and the stone crushing efficiency is improved. And disintegrating slag can be filtered, and the stone crushing effect is improved.

Problems solved by technology

[0003] In the patent document "CN208612586U A Stone Crusher for Civil Engineering", it has a good buffering effect on stones, and can produce three types of stones with different sizes. Turn on the turbo fan to draw air, and the dust enters the ventilation duct through the suction pipe and falls into the dust box to be collected. However, it lacks the screening function, and it is difficult to ensure that the particle size of the gravel is uniform after crushing, which will cause inconvenience in subsequent use. Moreover, it is difficult to effectively collect broken stones, and the dust generated during the crushing process is easy to disperse, seriously affecting air quality

At present, there is no civil engineering crushing device with reasonable and reliable structure, screening function and convenient gravel transportation.
