Two-layer continuous paving device for gravel materials for road construction

Abstract

The invention belongs to the technical field of building construction machinery, in particular to a double-layer continuous paving device for crushed stones for road construction, which includes a bearing mechanism and two paving mechanisms installed on the bottom surface thereof, and a shaping mechanism is installed on the paving mechanisms, The carrying mechanism includes a support plate and four legs respectively fixed at the four corners of its bottom surface, the bottom ends of the support legs are rotatably connected with rollers, and the top surface of the support plate is fixedly connected with two symmetrically arranged bearing boxes; According to the specific pavement requirements, turn the screw at the corresponding position, extend the slotted plate downwards from the bottom of the screed, and slot the pavement layer. When the next layer is paved, it can cross with the bottom layer to improve the attachment. At the same time, adjust the height of the slotted plate through the screw, control the depth of the slot, and control the width and interval of the slot by adjusting the number of drops and intervals of adjacent slotted plates. Make adjustments for higher applicability.

Description

technical field [0001] The invention belongs to the technical field of building construction machinery, and in particular relates to a double-layer continuous paving device for gravel materials used in road construction. Background technique [0002] From the meaning of the word, the road is the infrastructure for all kinds of trackless vehicles and pedestrians; according to its use characteristics, it can be divided into highways, urban roads, rural roads, factory and mine roads, forestry roads, examination roads, competition roads, automobile test roads, and workshop passages. As well as school roads, etc., in the construction of hard ground roads, the subgrade of the road needs to be paved with multi-layer crushed stones of different materials to ensure the use requirements. [0003] The paving mechanism of the existing double-layer continuous paving device for crushed stones used in road construction is relatively fixed. When paving the crushed stones, only simple layere...

AI Technical Summary

Problems solved by technology

[0003] The paving mechanism of the existing double-layer continuous paving device for crushed stones used in road construction is relatively fixed. When paving the crushed stones, only simple layered paving can be carried out, and there is only a simple layer between two layers of crushed stones Superimposed, the mutual adhesion of the two layers of stones is poor, it is impossible to pave roads with higher requirements, and it cannot meet the needs of the market
