Abstract

The invention relates to a gravel paving and compacting device for roadbed construction, which comprises a vehicle body, a lifting air cylinder is fixedly installed on the right side of the vehicle body, and a push plate is fixedly installed on the output end of the lifting air cylinder. According to the gravel paving and compacting device for roadbed construction, a motor is started, under transmission of a driving gear and a driven gear, a spiral pushing piece can rotate, so that gravel falling from a feeding hopper can be uniformly paved, redundant gravel can be pushed rightwards through a pushing plate and a baffle, paving flatness is guaranteed, a triangular-prism-shaped vertical block is arranged, the gravel can be pushed to a roadside position, thereby ensuring paving uniformity. By adjusting stretching and retracting of a telescopic air cylinder, left-right movement of a connecting plate and pushing of a connecting spring on the left side to stretch and retract, the feeding hopper can shake left and right under the elastic force of the connecting spring, and therefore the gravel in the feeding hopper can shake; and blockage of the feeding hopper caused by crushed stone pushing is avoided.

Description

technical field [0001] The invention relates to the technical field of roadbed construction, in particular to a gravel paving and compacting device for roadbed construction. Background technique [0002] The subgrade is a geotechnical structure formed by excavation or filling. The main function of the subgrade is to provide necessary conditions for the laying of tracks or road surfaces and the operation of trains or trains, and to bear the static and dynamic loads of tracks, rolling stock or road surfaces and traffic loads. At the same time, the load is transmitted and diffused to the depth of the foundation. The construction of subgrade engineering refers to the construction of machinery including shovel transportation machinery, excavation and loading machinery, engineering transportation vehicles and compaction machinery. [0003] When the existing crushed stone paving and compacting device for roadbed construction is paving the crushed stones, the crushed stones are conc...
