Convenient-jointing size-adjusting road surface crack sealing machine

Abstract

The invention discloses a convenient-jointing size-adjusting road surface crack sealing machine. The road surface crack sealing machine comprises a pushing handle, a battery box, a control board, a driving motor, an electric hydraulic rod and a protective tarpaulin, wherein the lower end of the pushing handle is fixedly provided with a cart main body, universal wheesl and moving wheels are mountedon the lower side of the cart main body, the battery box is fixedly arranged on the cart main body, the control board is connected to the upper end of the battery box, a feeding bucket is fixedly arranged on the cart main body, a bucket cover is mounted on the upper end of the feeding bucket, the driving motor is mounted inside the lower end of the feeding bucket, and a maintenance port is formedin the lower part of the feeding bucket. According to the convenient-jointing size-adjusting road surface crack sealing machine, through the stretch of the electric hydraulic rod, a joint sealing material plate is of a rhombus structure and the size of the joint sealing material plate is changed, and the lateral dimension of the inside of a frame formed by the joint sealing material plate is changed, so that the size of the frame formed by the joint sealing material plate can conform to cracks with different sizes, and the applicability of the device is increased.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a pavement joint filling machine for conveniently adjusting the filling size. Background technique [0002] Pavement seam filling machine is a common pavement repair equipment, its main function is to fill and repair the gaps on the pavement. Pavement cracking is a common pavement defect. Whether it is cement or asphalt pavement, once the pavement cracks, it will easily lead to damage to the subgrade under the cracks, and then the road surface will gradually form various damages, deformations and other defects. [0003] At present, for the repair of pavement cracks, it is usually to dig out the cracks, fill in the same raw materials, and then carry out the filling repair work again. However, the repair process of pavement cracks requires a large amount of engineering and takes a long time, which will seriously affect the normal traffic of the road section. Many un...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a road surface filling machine that can easily adjust the size of the joint filling, so as to solve the problem of the current road surface repairing method through the gap filler proposed in the above-mentioned background technology. The project consumes a lot of time and will seriously affect the normal operation of the road It will be opened to traffic, and the way of filling repair agent into the cracks of the road surface will increase the difficulty of repairing the road surface
