[0031] Embodiment 1: An asphalt concrete cutting device comprises a base plate 1, which is connected to a connecting frame 2, a protective box 3 is fixedly connected to the opposite end of the connecting frame 2, a rotating frame 4 is rotatably connected to both sides of the inner wall of the protective box 3, the top of the rotating frame 4 is fixedly connected to a fixed frame 5, the inner wall of the fixed frame 5 is slidably connected to a pull rod 6, the outer wall of the pull rod 6 is fixedly connected to a limiting plate 7, a spring 8 is arranged between the fixed frame 5 and the limiting plate 7, the inner wall of the rotating frame 4 is slidably connected to an insert block 9, the opposite end of the insert block 9 is fixedly connected to a cutting knife 11, the front end of the front connecting frame 2 is fixedly connected to a motor 12, one end of the spring 8 is connected to the limiting plate 7, the other end of the spring 8 is connected to the fixing frame 5, the outer wall of the limiting plate 7 is slidably connected to the inner wall of the fixing frame 5, and the inner wall of the insert block 9 is provided with a fixing groove 10 corresponding to the pull rod 6, the driving end of the motor 12 passes through the connecting frame 2 and the slide 13 in sequence, and the front end of the front rotating frame 4 is fixedly connected to the driving end of the motor 12.

[0032] Specifically, when the driving end of the motor 12 rotates, it drives the front rotating frame 4 to rotate, and when the front rotating frame 4 rotates, it drives the cutting knife 11 to rotate. When the cutting knife 11 rotates, it drives the inner wall of the protective box 3 of the rear rotating frame 4 to rotate. When disassembly is required, pull the pull rod 6 to make it disengage from the fixed groove 10, and then take out the cutting knife 11. When installing, insert the plug 9 into the rotating frame 4, and then release the pull rod 6. At this time, the spring 8 will bounce the limit plate 7, and the limit plate 7 is stuck in the inside of the fixed groove 10 when it is bounced, so as to facilitate the disassembly and installation of the cutting knife 11, which greatly reduces the maintenance cost and time.

[0033] Among them, a swivel 15 is fixedly connected to the top of the base plate 1, the inner wall of the swivel 15 is rotatably connected to the screw rod 14, the outer wall of the screw rod 14 is threadedly connected to the slide 13, the inner wall of the slide 13 is slidably connected to a plurality of fixed rods 16, the left end of the connecting frame 2 is fixedly connected to the right end of the slide 13, a plurality of universal wheels 23 are fixedly connected to the four corners of the bottom end of the base plate 1, an armrest 22 is fixedly connected to the left side of the top of the base plate 1, a distance reference ruler 17 is fixedly connected to the front side of the top of the base plate 1, and the bottom end of the fixed rod 16 is fixedly connected to the top of the base plate 1.

[0034] Specifically, when the height needs to be adjusted, the screw rod 14 is rotated to drive the slide 13 to move. When the slide 13 moves, the reference value on the distance reference scale 17 on one side can be used to understand whether the adjusted height meets the cutting height requirement. When the slide 13 moves, the outer wall of the fixed rod 16 will move. The fixed rod 16 prevents the slide 13 from being misaligned, so that the cutting height can be adjusted according to different needs.

[0035] Embodiment 2: As one of the optimized structural designs of Embodiment 1, Figure 1-Figure 5As shown, a water tank 18 is fixedly connected to the top of the base plate 1, a water pump 19 is fixedly connected to the top of the water tank 18, a connecting pipe 20 is fixedly connected to the left end of the water pump 19, the bottom end of the connecting pipe 20 passes through the water tank 18, a delivery pipe 21 is fixedly connected to the right end of the water pump 19, the bottom end of the delivery pipe 21 is fixedly connected to the inner wall of the protection box 3, and a water inlet is fixedly connected to the rear side of the top end of the water tank 18.

[0036] Specifically, during cutting, water is sent into the water tank 18 from the water inlet, and then the water pump 19 is turned on to suck the water inside the water tank 18 through the connecting pipe 20. The sucked water will be sent to the protection box 3 from the delivery pipe 21. The water sent to the protection box 3 can cool down the cutting knife 11. The set protection box 3 can effectively block the cutting slurry water and is easy to use.

[0037] Working principle: when cutting is required, the front rotating frame 4 is driven to rotate by the driving end of the motor 12, and the cutting knife 11 is driven to rotate when the front rotating frame 4 rotates. When the cutting knife 11 rotates, it will drive the rear rotating frame 4 to rotate on the inner wall of the protection box 3. When disassembly is required, the pull rod 6 is pulled to disengage it from the fixed groove 10, and then the cutting knife 11 can be taken out. When installing, the plug 9 is inserted into the rotating frame 4, and then the pull rod 6 is released. At this time, the spring 8 will bounce the limit plate 7, and when the limit plate 7 is bounced, it is stuck in the fixed groove 10, so that the cutting knife 11 can be easily disassembled and installed, which greatly reduces the maintenance cost and time. When cutting, water is sent into the water storage tank 18 from the water injection port, and then Turn on the water pump 19 to suck out the water in the water tank 18 through the connecting pipe 20, and the sucked water will be sent to the protection box 3 from the delivery pipe 21. The water sent to the protection box 3 can cool down the cutting knife 11. The set protection box 3 can effectively block the cutting slurry water and is easy to use. When the height needs to be adjusted, the screw 14 is rotated to drive the slide 13 to move. When the slide 13 moves, the reference value on the distance reference scale 17 on one side can be used to understand whether the adjusted height meets the cutting height requirement. When the slide 13 moves, it will move on the outer wall of the fixed rod 16. The fixed rod 16 prevents the slide 13 from being misplaced, so that the cutting height can be adjusted according to different needs.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
