Road surface cutter capable of cutting circular spherical surface

Abstract

The invention discloses a road surface cutter capable of cutting a circular spherical surface. The road surface cutter comprises a base, circular guide wheels and rear wheels capable of adjusting the direction of a central axis; the base comprises an adjusting surface and a working surface; a work circle center is arranged in the center of the outer edge of the adjusting surface; pin shafts are arranged at the two ends of the adjusting surface; a plurality rows of through holes are arranged on the adjusting surface in the width direction of the cutter; cutting discs are assembled at the bottom of the working surface by cutting shafts; the distance between the work circle center and the cutting disc can be adjusted by connecting different rows of through holes with the pin shafts; and the central axes of the circular guide wheels and the cutting discs are fixed and opposite to the work circle center of the adjusting surface of the base. According to the road surface cutter, circular surfaces can be cut by the cutter; radius of circular surfaces can be changed by adjusting the connection of the through holes and the pin shafts on the adjusting surface; the cutting depth and angle can be changed by moving a first adjusting rocking bar up and down; working modes of cutting straight lines and cutting circular surfaces can be switched by moving a second adjusting rocking bar up and down; and the straight line cutting depth also can be adjusted at a straight line cutting mode.

Description

technical field [0001] The invention relates to a road surface cutting machine, in particular to a road surface cutting machine capable of cutting circular spherical surfaces. Background technique [0002] Road cutting machine is an important equipment used in road construction, and is widely used in grooving, resting and cutting of concrete and asphalt pavement. The front wheel of the road cutting machine is a straight-running guide wheel, which can only lead the cutting machine to cut along a straight line. The application range is narrow and cannot meet the increasingly complex needs of road operations. For example, when cutting a circle, it is powerless and can only cut approximate Rounded rectangles cause secondary destructive cross cutting and low work efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is that the current road surface cutting machine can only cut straight lines but not round surfaces, and has a...
