Breaking hammer for pavement patching

Abstract

The breaking hammer for pavement patching comprises a fixed disc, a driving shaft rod is inserted into the axis of the fixed disc in a penetrating mode, breaking teeth are fixedly connected to the middle of the side surface of the fixed disc at equal intervals, and mounting grooves are formed in the two edges of the side surface of the fixed disc. During specific use, the fixed disc is driven by the crushing device to rotate, the beneficial effects of rotating crushing are that the crushing area is small, the damage degree is small, the damaged part at the joint can be quickly crushed, and when the depth of the crushed part is large, the crushing teeth downwards crush, so that the crushing effect is good. And the annular crushing mechanism can crush the two side surfaces of the crushing groove, so that the rule of a crushing surface is ensured, and the problem that the crushing surface is increased due to a traditional crushing device and the attractiveness after later repair is not facilitated is also avoided. And the fine grinding surface and the rough grinding surface can grind the crushed groove wall, so that after the crushed groove wall is repaired in the later period, the appearance is attractive, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of road surface repair devices, in particular to a breaker for road surface repair. Background technique [0002] Under the long-term use of the road pavement, due to the influence of weather and load, the pavement will be damaged. Since the damage is usually not continuous, in the later repair, it is usually broken in the damaged place, and the damaged place will be broken. Dig out the pit, and then fill the pit with cement and asphalt. [0003] However, in the actual pavement repair process, the pavement is divided into blocks of the same size, mainly to prevent the impact of thermal expansion and contraction on the pavement, and at the joints of the road, stones and sundries are often dropped and water is collected. It is easy to appear blocky damage at the joints. When dealing with this situation, the part with a large loss is generally cut, and then the cut part is processed. This is slow in efficiency...

Problems solved by technology

[0003] However, in the actual pavement repair process, the pavement is divided into blocks of the same size, mainly to prevent the impact of thermal expansion and contraction on the pavement, and at the joints of the road, stones and sundries are often dropped and water is collected. It is easy to appear blocky damage at the joints. When dealing with this situation, the part with a large loss is generally cut, and then the cut part is processed. This is slow in efficiency and the operation steps are cumbersome. Therefore, it is proposed A breaking hammer that directly repairs broken joints
