Cutting radius adjusting mechanism of circumference cutter

Abstract

The invention relates to a cutting radius adjusting mechanism of a circumference cutter. The circumference cutter comprises a base and a cutter body arranged on the base, wherein the cutter body comprises a cutting blade and a power device for driving the cutting blade to rotate and move; the cutter body further comprises a horizontal slide plate which is arranged on the base in a horizontal sliding manner, wherein the cutting blade and the power device are arranged on the horizontal slide plate to horizontally move along with the horizontal slide plate; a locking plate mechanism which is used for selectively permitting or blocking horizontal sliding of the horizontal slide plate is arranged on the base. According to the cutting radius adjusting mechanism, the adjustment of the cutting radius of the circumference cutter is realized by adjusting the horizontal slide plate; the radius adjusting mechanism is simple in structure, easy and convenient to adjust, so that the application range of the circumference cutter is expanded; moreover, the circumference cutter is strong in integrity, small in size, good in stability, and easy and convenient to adjust.

Description

technical field [0001] The invention relates to a cutting radius adjusting mechanism of a circular cutting machine. Background technique [0002] After the asphalt road is used for a period of time, the road surface will be damaged one after another, especially when many types of manhole covers are installed on the road, there will be pits, cracks, cracks, etc. on the road around the manhole cover, which need to be partially repaired. Traditional methods of repairing existing manhole covers include cutting, excavating, and then filling with new material. However, the traditional cutting machine first cuts the road surface in a straight line, and then adjusts the direction of the cutting machine to cut roughly in a quadrangular shape. In this method, the operator cuts the cutting part into a quadrangular shape, and the shape of the round manhole does not match the cutting part. It not only brings inconvenience to the traffic of vehicles, but also has an unattractive appearan...

Problems solved by technology

However, the traditional cutting machine first cuts the road surface in a straight line, and then adjusts the direction of the cutting machine to cut roughly in a quadrangular shape. In this method, the operator cuts the cutting part into a quadrangular shape, and the shape of the round manhole does not match the cutting part. It not only brings inconvenience to the traffic of vehicles, but also has an unattractive appearance, and the area to be filled with new materials is relatively large, requiring a large amount of new materials to be filled, and the cost is high

[0003] For the traditional quadrangular cutting method, there are some cutting machines that can cut the road outside the manhole cover into a circle in the prior art, but these circular cutting machines can only cut within a limited radius due to their own size and other factors. The flexibility is poor, the scope of adaptation is small, and it has the disadvantages of poor efficiency in all aspects
