Concrete pavement joint cutter

Abstract

The invention discloses a concrete pavement joint cutter, and relates to the technical field of road construction, the concrete pavement joint cutter comprises a control mechanism, the bottom surface of the control mechanism is fixedly connected with a base mechanism, one side of the control mechanism is provided with a power mechanism, and the bottom surface of the power mechanism is fixedly connected with the top of the base mechanism; a guide wheel mechanism is fixedly installed on the side, away from the control mechanism, of the base mechanism, and a cutting mechanism is arranged on the front face of the power mechanism. Through combination of the rotating shaft and the air outlet device, a contact plate is conveniently pushed to move upwards to enable a pressing plate device to move in a compression cavity through impact force generated when the cutting blade makes contact with a road surface during cutting of the cutting blade, and therefore air in the compression cavity is discharged outwards through air outlet holes; dust and gravels on the surface of the cutting blade fall off along with airflow blown out of the air outlets, the gravels in the dust are prevented from being attached to the surface of the blade, the rotation resistance of the blade in the road surface can be increased when the blade cuts, and abrasion of the blade is aggravated.

Description

technical field [0001] The invention relates to a seam cutting machine, relates to the technical field of road construction, in particular to a seam cutting machine for concrete pavement. Background technique [0002] When the concrete pavement is being built, a slitting machine is usually used to slit the pavement, so that the pavement has expansion and contraction space when it expands under high temperature, and will not cause the pavement to burst, so that the pavement has a longer service life. There are following problems at prior art: [0003] 1. In the prior art, when the seam cutting machine is cutting the road surface, the friction between the blade and the cement road surface will generate a large amount of dust, and the gravel in the dust will adhere to the surface of the blade, which will increase the rotation of the blade in the road surface when cutting. Resistance, exacerbating the problem of blade wear; [0004] 2. In the prior art, for some cutting machin...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a concrete pavement slitting machine, one of the purposes of which is to have the ability to blow off the gravel attached to the surface of the blade when cutting, and to solve the problem of friction between the blade and the cement pavement when the pavement is cut. A large amount of dust will be generated, and the gravel in the dust will adhere to the surface of the blade, which will increase the resistance of the blade to rotate in the road surface and aggravate the wear of the blade when cutting; another purpose is to solve the problem of The water cools down the blade, so that the blade will not be damaged due to the severe high temperature generated by friction when cutting, so as to achieve the effect of using the blade for a long time
