A construction concrete polisher with synchronous adjustment for grinding and cutting

Abstract

The invention discloses a synchronous polishing and cutting adjusting concrete polishing machine used for construction. The machine comprises a vehicle frame, a handle, supporting legs, idler wheels,a polishing motor and a polishing disc; a horizontal supporting board is arranged in an adjusting cavity, and a pneumatic cylinder arranged vertically downwards is further fixedly installed on the vehicle frame; a polishing cavity with a downward opening and a cutting cavity with a downward opening are fixed to the lower side of the supporting board; the center of the polishing disc is fixed to anoutput shaft of the polishing motor; and a vertical transmission gear is coaxially fixed to a first rotary shaft, a driven gear coaxially fixed to a second rotary shaft is engaged with the lower portion of the transmission gear, a horizontal cutting motor is fixed to the lower side of a cutting motor fixing board, and multiple cutting blades are coaxially fixed to the second rotary shaft. By theadoption of the machine, the supporting board is pushed up and down through the arranged pneumatic cylinder, the pressure applied by the polishing disc to aggregate is adjusted, polishing efficiency is improved, meanwhile, the cutting blades make contact with the aggregate above the ground and cut the aggregate, the polishing difficulty is reduced, and a treatment effect is improved.

Description

technical field [0001] The invention relates to building construction equipment, in particular to a building concrete polisher with synchronous adjustment for grinding and cutting. Background technique [0002] The concrete grinder is suitable for indoor simulation of the grinding effect of automobile tires on highway asphalt pavement, and accelerates the grinding of the aggregate used in the road surface, and evaluates the wear resistance of the aggregate by the measured grinding value of the aggregate. [0003] When the grinder is in use, some aggregates with high protrusions and large volume cannot be quickly polished, which reduces the construction efficiency. These aggregates are often removed manually, which is difficult to construct and labor-intensive. Therefore, Therefore, it is necessary to improve the existing concrete grinder to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a construction concret...
