[0035] The working principle and use process of the present invention are as follows: first, universal wheels 2 are fixedly installed at the four corners of the bottom of the frame 1, and the push rod 7 fixedly connected to the back of the universal wheel 2 facilitates the pushing of the frame 1 to move, and a cutting mechanism 3 is arranged inside the universal wheel 2, and a protection frame 31 in the cutting mechanism 3 is slidably connected to the inner wall of the side of the frame 1, and a support frame 32 is fixedly connected to the bottom of the inner wall of the protection frame 31, and a driving motor 310 is installed on the support frame 32, and then the driving motor 310 is connected to the power supply and controlled to start, because the output shaft of the driving motor 310 is fixedly sleeved with a pulley and a rotating drum 33 to support the rotation of the sleeved rotating drum 33 through a V-belt transmission, so the driving motor 310 can drive the rotation of the rotating drum 33 after starting, and the threaded rod 34 is inserted from the side of the support frame 32 away from the rotating drum 33, and the second internal threaded disk 39, the second toothed disk 38, the sleeve 37, the first toothed disk 36, the first ...8, the first internal threaded disk 39, the second toothed disk 39, the sleeve 37, the first toothed disk 39, the first internal threaded disk 39, the first toothed disk 39, the first toothed disk 39, the first internal threaded disk 39, the first toothed disk 39, the first toothed disk 39, the first toothed disk 39, the first toothed disk 39, the first toothed disk 39, the first toothed disk 39, the first The threaded disc 35, and because the first internally threaded disc 35 and the second internally threaded disc 39 are both threadedly connected to the outer wall of the threaded rod 34, when the threaded rod 34 and the first internally threaded disc 35 are screwed together, the second toothed disc 38, the sleeve 37, and the first toothed disc 36 are clamped to prevent movement, and the spacing between the second internally threaded disc 39 and the first toothed disc 36 can be controlled by the sleeve 37, because the inner walls of the second internally threaded disc 39 and the first toothed disc 36 are fixed with the blocks 311 arranged in an equidistant array and are slidably connected to the inner wall of the card groove 312 provided on the outer wall of the threaded rod 34, it is convenient for the threaded rod 34 to drive the second internally threaded disc 39 and the first toothed disc 36 to rotate, and because the end of the threaded rod 34 close to the rotating drum 33 is polygonal and can slide into the inner wall of the rotating drum 33, it can drive the threaded rod 34 to rotate when the rotating drum 33 rotates, so that the second toothed disc 38 and the first toothed disc 36 can cut the ground and facilitate grooving;

[0036] By arranging a telescopic mechanism 4 above the cutting mechanism 3, the rotation of the rotating rod 41 can be driven by the hand-cranked rotating disk 45, because the outer wall of the rotating rod 41 is connected to the internal thread of the sliding block 44, and the top of the sliding block 44 is slidably connected to the top inner wall of the frame 1, so that when the rotating rod 41 is rotated, the sliding block 44 can move, and when the sliding block 44 approaches the mid-vertical line of the frame 1, the sliding block 44 can push the movable rod 43, and the movable rod 43 can push the fixed block 42, so that the protection frame 31 can move downward, so as to facilitate the adjustment of the cutting depth of the second toothed disc 38 and the first toothed disc 36. On the contrary, when the protection frame 31 needs to move upward, the rotating rod 41 can be rotated in the opposite direction. At the same time, a connecting block 46 is fixedly connected to the side of the protection frame 31 away from the rotating drum 33, and the connecting block 46 is slidably connected to the inner wall of the other side of the frame 1, so as to effectively facilitate the protection frame 31 to move up and down smoothly;

[0037] The side stop mechanism 5 is provided, and the fixing plate 55 can be supported by the support frame 32. A T-shaped limit rod 54 is fixedly connected to the bottom of the fixing plate 55, and the two limit blocks 53 can be limited by the T-shaped limit rod 54. A baffle plate 51 is fixedly connected between the two limit blocks 53 on the side close to each other, so that the baffle plate 51 can move up and down. Because a tension spring 56 is fixedly connected between the baffle plate 51 and the side close to the fixing plate 55, the baffle plate 51 can block the threaded rod 34, thereby avoiding the problem of the threaded rod 34 being disengaged when rotating. At the same time, when the threaded rod 34 needs to be taken out, the lifting block 52 is lifted upward, and the lifting block 52 can drive the baffle plate 51 to move upward to take out the threaded rod 34.

[0038] By setting up the water spraying mechanism 6 and opening the bucket cover 63 on the water inlet bucket 62, water can be effectively poured into the water filling mechanism 61. When the driving motor 310 is started, the controller controls the electric control valve on the water outlet pipe 64 to open, thereby effectively realizing that the water inside the water filling mechanism 61 can flow into the inside of the water outlet pipe 64, and flow into the inside of the connecting hose 65 through the water outlet pipe 64, and then enter the inside of the water collecting pipe 67 after being transported to the inside of the water inlet pipe 66, thereby effectively realizing the outflow from the inside of the two water spraying capillaries 68, so as to facilitate the first toothed disc 36 and the second internally threaded disc 39 to spray water during the cutting process, which can suppress dust and reduce the wear of the first toothed disc 36 and the second internally threaded disc 39.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
