Road surface cutting machine with cutting pieces capable of being rapidly switched

Abstract

The invention discloses a road surface cutting machine with cutting pieces capable of being rapidly switched. The road surface cutting machine comprises a bottom plate, four rectangularly-distributeduniversal wheels are fixedly connected to the bottom side of the bottom plate, and a pushing handle is fixed to the upper side of the end, close to the universal wheels, of the bottom plate. Paired supporting rods are fixedly connected to the top side of the middle of the bottom plate, a rotary shaft is hinged to the ends, away from the bottom plate, of the supporting plates, and the outer side, close to one end of one of the supporting rods, of the rotary shaft is sleeved with a second belt wheel. Two corresponding hinging plates are hinged to the outer side, between the second belt wheel andthe other supporting rod, of the rotary shaft and are each in a triangular shape, and the three corners of one of the hinging plates correspond to the three corners of the other hinging plate. The first cutting piece, the second cutting piece and the third cutting piece are hinged between the two hinging plates. According to the road surface cutting machine, the structure is novel, the three cutting pieces are simultaneously hinged through the paired triangular hinging plates, rapid recombination and switching of the cutting pieces are achieved, the work efficiency is greatly improved, and popularization is easy.

Description

technical field [0001] The invention relates to the field of road construction, in particular to a road cutting machine capable of quickly switching cutting blades. Background technique [0002] Pavement cutting machine is a special equipment widely used in pavement expansion joint cutting or asphalt pavement repair. As the road construction in our country is getting more and more perfect, the task of road maintenance is also getting bigger and bigger. The existing road cutting machine takes too long to replace the cutting blades, and basically uses The single-piece cutting process does not realize the organic combination of cutting pieces of different specifications, not to mention the low efficiency. Once the cutting piece is damaged, it will immediately stop working and replace the cutting piece, which will delay the overall process, so there are certain defects. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the...
