Problems solved by technology

At present, the paving is mainly carried out with the cooperation of manpower and machinery, and the manpower consumption is relatively large. At the same time, because the laying has very strict requirements on the uniformity of gravel in the road, the requirements for manpower are relatively high.
At present, there are few studies on purely mechanical equipment for laying gravel, and related machinery with relatively high automation only crushes gravel and screens it before adding it to the machine for road subgrade laying

Abstract

The invention relates to an efficient stone breaking and paving device. A coarse breaking cavity, a fine breaking cavity and a sieving and conveying cavity are arranged, so that stones can be broken into sizes according with paving conditions in real time in a paving process. Specific parts of the coarse breaking cavity and the fine breaking cavity are reasonably set so that the stones are uniformly broken; specific parts of the sieving and conveying cavity are set so that the sizes and specific distribution of the broken stones for paving a road are uniform and stable and the quality and thestability of road construction are improved.

Description

technical field [0001] The invention belongs to the field of road construction and construction, and in particular relates to a high-efficiency stone crushing and paving device for roadbed laying. Background technique [0002] Roadbed is a very important part of road construction, and gravel is a very important paving material in the process of laying the roadbed, and the requirement for paving gravel is fine and uniform. At present, the paving is mainly carried out with the cooperation of manpower and machinery, and the manpower consumption is relatively large. At the same time, because the laying has very strict requirements on the uniformity of gravel in the road, the requirements for manpower are relatively high. At present, there are few studies on purely mechanical equipment for laying gravel, and related machinery with relatively high automation only crushes and screens the gravel and adds it to the machine for road subgrade laying. Contents of the invention [000...
