Crack sealing machine for road crack disposal

Abstract

The invention discloses a crack sealing machine for road crack disposal, which belongs to the technical field of road crack disposal. The crack sealing machine comprises a machine body, a stock bin is arranged in the machine body, a feed inlet cover plate is arranged above the stock bin, a stirring assembly is arranged in the stock bin, a heating assembly is arranged in the machine body, and the stock bin is wrapped by the heating assembly; and an impurity adsorption assembly is arranged behind the machine body. According to the crack sealing machine for road crack disposal, material fusion is more uniform, material caking is avoided, internal materials cannot be dried up through temperature control, the situation that the materials are dried up and are difficult to discharge is avoided, cracks are cleaned in advance, the situation that the crack sealing effect is affected by impurities in the cracks is prevented, the quality after crack sealing is effectively guaranteed, the workload of workers is automatically reduced, the work comfort is improved, transverse adjustment can be carried out according to the position of the gap, the gap filling accuracy is improved, the overall adaptability is improved, gaps in different positions can be automatically filled conveniently, and the gap filling speed and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of highway crack treatment, in particular to a crack filling machine for highway crack treatment. Background technique [0002] Asphalt road is a general term for pavements that use asphalt as a binder to pave the surface. Asphalt highway is a pavement structure in which a certain thickness of asphalt mixture is paved as a surface layer on a flexible base or a semi-rigid base. Compared with gravel roads, the strength and stability of asphalt roads are greatly improved; compared with cement concrete roads, asphalt roads have a smooth surface without joints, small driving vibration, low noise, fast open traffic, easy maintenance, and are suitable for phased construction. , is an important structural form of my country's highways. [0003] However, because cracks are a common disease of asphalt roads, they are extremely harmful to the road, especially in winter and spring, due to the infiltration of rain and s...

Problems solved by technology

[0003] However, because cracks are a common disease of asphalt roads, they are extremely harmful to the road, especially in winter and spring, due to the infiltration of rain and snow water from time to time, under the action of traffic load, the road surface disease that is already in a cracked state is even more serious. severe, eventual destruction

The road maintenance department usually uses the joint filling machine to pour asphalt into the cracks, but the existing joint filling machines have the following problems: first, the joint filling machine does not clean the cracks before filling the joints, which affects the repair effect of the cracks; Some seam filling machines cannot be adjusted according to the position of the gap, resulting in a waste of time for gap alignment
