[0022] A first screw rod 3 is arranged inside the cutting device body 1, and a driving block 4 is sleeved on the first screw rod 3, a driving chamber 5 is arranged on the top of the driving block 4, and a second screw rod 10 is arranged on the top of the driving chamber 5, a movable plate 12 is sleeved on the second screw rod 10, and a third rotary drive mechanism 9 is fixed to the bottom of the movable plate 12, and the output end of the third rotary drive mechanism 9 is connected to a cutting disc 8 through a roller;

[0023] The outer side of the cutting disc 8 is evenly distributed with cutter heads 16, and the cutter heads 16 are all made of nickel alloy. The third rotary drive mechanism 9 drives the cutting disc 8 to rotate, and uses the external cutter heads 16 to cut the wall;

[0025] The second rotary drive mechanism 13 drives the driving gear 14 to rotate, so that the driven gear 15 and the second screw rod 10 rotate, so that the movable plate 12 moves up and down along the second screw rod 10, and then drives the third rotary drive mechanism 9 and the cutting blade 8 to adjust the height, thereby automatically adjusting the cutting height to meet different cutting requirements;

[0026] Guide frames 11 are provided on both sides of the second screw rod 10, and guide holes matching the guide frames 11 are provided at both ends of the movable plate 12 to guide and limit the movable plate 12;

[0027] A first rotary drive mechanism 2 is fixed to one side of the cutting device body 1, and an output end of the first rotary drive mechanism 2 is connected to a first screw rod 3;

[0028] When the cutter head 16 rotates to cut the wall, the first rotary drive mechanism 2 drives the first screw rod 3 to rotate, so that the drive block 4 moves along the first screw rod 3, thereby driving the cutting disc 8 to move toward the wall, without the need for manual feeding by workers, saving time and effort, and improving construction efficiency;

[0029] The end of the cutter head 16 close to the cutting disc 8 is provided with an insert block 18, and the outer side of the cutting disc 8 is evenly provided with slots 19, and the insert block 18 and the slots 19 are fixedly connected by bolts 20;

[0030] The tops of the bolts 20 are locked and fixed by nuts 17, which is conducive to replacing a single cutter head 16 when it is damaged, without having to replace the cutting disc 8 as a whole, and the operation is more convenient;

The third rotary drive mechanism 9 drives the cutting disc 8 to rotate, and uses the external cutter head 16 to cut the wall. At the same time, the first rotary drive mechanism 2 drives the first screw rod 3 to rotate, so that the drive block 4 moves along the first screw rod 3, thereby driving The movable cutting disc 8 moves toward the wall, and there is no need for manual feeding by workers, which saves time and effort and improves construction efficiency.
