[0031] See Figure 1The road repair cutting device shown includes a chassis 1, and rollers 101 are installed at the front and rear ends of the chassis 1. Under the action of the rollers 101, the lower end surface of the chassis 1 is lifted off the ground by more than 1 cm. An equipment compartment 2 is provided in the chassis 1, and a battery 3 and a controller 4 are installed in the equipment compartment 2. The controller 4 is connected to an independent control switch, which is a waterproof switch installed on the outside of the chassis 1 and is used to control the speed of the cutting unit. The battery 3 is connected to the controller 4. Inside the chassis 1, a cutting compartment 5 is formed on the right side of the equipment compartment 2. An L-shaped water tank 6 is provided on the side of the equipment compartment 2 away from the cutting compartment 5. A water inlet pipe 61 is provided on the side of the water tank 6 near the top, and a pipe cover 62 is provided at the mouth of the water inlet pipe 61. A height-adjustable cutting unit 7 is provided in the cutting compartment 5. The cutting unit 7 is powered by the battery 3, and the cutting speed is controlled by the controller 2. A water pump 8 is installed on the top of the chassis 1, and the water pump 8 cooperates with the cutting unit 7.

[0032] In the above technical solution, the cutting depth of the cutting unit 7 is adjustable, which can be set according to the cutting depth required for the road surface to meet the needs of different cutting depths.

[0033] In the above technical solution, the cutting unit 7 can be retracted into the box body 1, so as to avoid damage to the cutting unit 7 when the box body 1 is moved.

[0034] During high-speed cutting, water in the water tank 6 is pumped by the water pump 8 to cool the cutting unit 7 and reduce dust in the cutting chamber 5 .

[0035] See Figure 1 As shown, a sealing edge 51 is provided at the bottom edge of the cutting chamber 5, and the lower end surface of the sealing edge 51 contacts the ground.

[0036] The function of the sealing edge 51 is to increase the sealing performance. During the cutting process, most of the dust generated by cutting is located in the cutting chamber 5 and dust is reduced by atomizing and spraying.

[0037] See Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the cutting unit 7 includes a machine cover body 71, a waterproof motor 72 is fixedly installed at the rear end axis of the machine cover body 71, the output shaft of the waterproof motor 72 is inserted into the interior of the machine cover body 71 and a saw blade 73 is installed thereafter, and a part of the saw blade 73 is exposed to the outside of the machine cover body 71, and an arc-shaped pipe 74 is provided at the upper position of the inner wall of the machine cover body 71, and both ends of the pipe 74 are inserted into the outside of the machine cover body 71, and both ends of the pipe 74 are provided with a first atomizing nozzle 755, and a second atomizing nozzle 75 is provided at the position of the pipe 74 corresponding to the saw blade 73, and the pipe 74 is connected to the saw blade 73. A branch pipe 76 is connected, and a folding pipe 77 is provided between the branch pipe 76 and the water pump 8. Two or more guide rods 78 are provided on the top of the machine cover body 71. The guide rods 78 pass through the chassis 1 upward. A spring 79 is provided on the guide rods 78. The spring 79 acts between the chassis 1 and the machine cover body 71. Under the action of the spring 79, the machine cover body 71 moves downward. A screw 710 is provided on the top of the machine cover body 71. After the screw 710 passes through the chassis 1 upward, it is equipped with an adjustment sleeve 711. A handle 712 is provided in a ring on the outer wall of the adjustment sleeve 711.

[0038] In the above technical solution, the position of the machine cover body 71 can be adjusted by operating the adjustment sleeve 711 on the outside of the chassis 1. When cutting is required, the machine cover body 71 reaches the specified cutting depth under the dual action of gravity and spring by rotating the adjustment sleeve 711 upward. Before descending, it is necessary to turn on the waterproof motor in advance to ensure that the saw blade 73 starts to descend at a high speed, and starts to saw the ground material when descending.

[0039] The first atomizing nozzle can spray atomized water vapor outside the machine cover body 71 to achieve the purpose of dust reduction, and the second atomizing nozzle can spray atomized water vapor toward the saw blade 73 to complete the cooling of the saw blade 73.

[0040] See Figure 2 As shown, the inner wall of the cutting chamber 5 is covered with a sound insulation layer 55 .

[0041] The provision of the sound insulation layer 55 can absorb the noise generated during the process of sawing the ground, thereby reducing noise pollution to the surroundings.

[0042] See Figure 1 As shown, the outside of the battery 3 is filled with a buffer pad 33 .

[0043] The provision of the buffer pad 33 can provide a technical effect of shockproof protection for the battery 3 .

[0044] See Figure 1 As shown, a counterweight 66 is provided in the chassis 1 on the side of the water tank 6 away from the cutting chamber.

[0045] The counterweight 66 can increase the weight of the chassis 1, making the operation of the device more stable.

[0046] Operation method:

[0047] The device is transported to the construction location where ground cutting is required by the transfer equipment, and the device is pushed to the construction point. Then the waterproof motor is started by the controller to start the operation. The waterproof motor drives the saw blade to rotate at high speed. When the speed of the waterproof motor is stable, the water pump is started, and the position of the adjustment sleeve is adjusted to make the machine cover move downward. The saw blade then moves downward and begins to cut into the ground. When the cutting depth is reached, the position adjustment of the adjustment sleeve is stopped, and the device is pushed to move along the required cutting direction, and the saw blade completes the cutting of the ground.
