Pavement joint cutting machine capable of avoiding cutting dead angle

Abstract

The invention discloses a pavement joint cutting machine capable of avoiding the cutting dead angle. The pavement joint cutting machine comprises a connecting frame and a water tank, wherein a first connecting box is connected to the center part of the upper surface of the connecting frame through welding, and a bottom frame is movably connected to the outer side of the middle part of a first connecting rod; the front side of the first connecting box is provided with a second servo motor which is connected to the upper surface of the connecting frame through welding, the front side of a thirdconnecting rod is fixedly connected with a connecting device, and a second connecting rod is located on the left side of the interior of the connecting frame; and the upper part of a first connectingblock penetrates through the connecting frame, the upper part of the interior of a connecting cavity is fixedly connected with a first motor, and the left side of a sixth connecting rod is fixedly connected with the connecting device. According to the pavement joint cutting machine capable of avoiding the cutting dead angle, the cutting dead angle can be prevented, the device does not need to be rotated when a joint is cut, the cutting depth can be adjusted, the durability of the device is high, and the dustproof effect is good.

Description

technical field [0001] The invention relates to the related technical field of road surface machinery, in particular to a road surface cutting machine which avoids cutting dead angles. Background technique [0002] During the pavement laying process, after the ground hardens, a seam needs to be reserved at a certain distance for the thermal expansion and contraction of the road surface. The seam cutting is an indispensable link in road construction, which directly affects the strength and life of the road surface. The seam cutting is generally performed with a road cutting machine, but the general road cutting machines on the market have some disadvantages, such as: [0003] 1. The position of the cutting knife of a road surface cutting machine with the application number 201810459349.X is fixed and cannot be moved in the horizontal direction inside the device, so there will be a cutting dead angle on the right side of the cutting knife, which increases the workload; [000...
