Paver with adjustable paving width

Abstract

The invention provides a paver with adjustable paving width. The paver comprises a host, a screed plate main body and a hydraulic telescopic screed plate, wherein a left side and a right side of the host are respectively provided with a traction arm, the host is connected with the traction arms through a connection device, the traction arm is connected with the hydraulic telescopic screed plate through an articulated shaft, the traction arm comprises a main traction arm and two rear traction arms, the main traction arm is connected with two rear traction arms in U shape through the articulated shaft, and the hydraulic telescopic screed plate comprises an anti-distortion device. Two traction arms are symmetrically arranged at two sides of a central line of the screed plate main body, the screed plate is capable of applying tightening force to the screed plate main body by adjusting two traction arms, and the U-shaped rear traction arms can be used for improving the reliability of the traction through the direct connection with the hydraulic telescopic screed plate; the bend distortion and the torsion distortion of the screed plate main body are reduced by setting the anti-distortion device. The paver has the advantages of being simple in structure, high in reliability, and high in paving flatness.

Description

technical field [0001] The invention belongs to the field of road surface operation engineering, in particular to a paving machine with adjustable paving width. Background technique [0002] At present, most of the pavers used in road construction are stabilized soil pavers and multi-functional pavers. When paving stabilized soil materials, due to the thick layer, the spiral distributor is required to provide more At this time, it is necessary to increase the distance between the screed and the screw distributor to change the elevation of the paving material to meet the supply of materials. However, the distance between the screed and the auger of most paver machines is fixed, and the traction arm of the screed on the paver is integrated, and its length cannot be adjusted. Therefore, the usual method is to add a backing plate on the connection surface between the screed and the traction arm to adjust the distance between the auger and the screed. This method has a small amo...

However, the distance between the screed and the auger of most paver machines is fixed, and the traction arm of the screed on the paver is integrated, and its length cannot be adjusted

Therefore, the usual method is to add a backing plate on the connecting surface of the screed and the traction arm to adjust the distance between the auger and the screed. This method has a small amount of adjustment, and when the layer is thick, it cannot meet the high compactness requirements. , affect the paving quality, and it is inconvenient to disassemble and install the connection between the traction arm and the screed. At the same time, the instability of the traction arm causes the paving effect of the paver to be poor and the density is not high
