Uniform stone crushing device for highway construction

Abstract

The invention discloses a stone uniform crushing device for highway construction, and belongs to the technical field of stone crushing devices.The stone uniform crushing device comprises collecting equipment and crushing equipment capable of sliding on the collecting equipment, a feeding port is formed in the collecting equipment, a discharging port of the crushing equipment is inserted into the feeding port, and the crushing equipment comprises a plurality of crushing rollers matched with one another; buffering devices installed in the feeding port are arranged on the two sides of the discharging port of the crushing equipment, each buffering device comprises a folding baffle for sealing the feeding port and a buffering piece located below the discharging port of the crushing equipment, and the collecting equipment comprises a material collecting box and a screening device detachably installed in the material collecting box. By adjusting the position of the discharge port after crushing, crushed stones uniformly fall on the screening device to be screened; the problem that the screens are prone to being blocked is solved through the double-layer staggered screens, the screening device is turned over when the screens are blocked to affect efficiency, stones blocked in screen gaps are separated from the screen gaps under the impact of falling stones, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of stone crushing devices, and the disclosure relates to a stone crushing device, and more particularly, to a uniform stone crushing device for highway construction. Background technique [0002] During highway construction, it is necessary to crush the stones before laying the pavement. After crushing, the stones need to be screened. The stones whose volume exceeds the specified standard need to be crushed a second time. The screening of stones generally uses sieve plates. It is easy to get stuck in the sieve gap of the sieve plate, which is inconvenient to clean and affects the efficiency. The present invention proposes a new solution to the above problems. SUMMARY OF THE INVENTION [0003] In order to overcome at least one of the above disadvantages, the present invention provides a device for uniform crushing of stone materials for highway construction. Object of the present invention can be achieved ...

AI Technical Summary

Problems solved by technology

[0002] During road construction, stones need to be crushed to pave the road. Stones need to be screened after crushing. Stones whose volume exceeds the specified standard need to be crushed twice. Stones are generally screened using sieve plates, and stones are screened during the screening process. It is easy to get stuck in the sieve gap of the sieve plate, which is inconvenient to clean and affects the efficiency. The present invention proposes a new solution to the above problems
