[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] An adjustable grooving machine, such as Figures 1-7 As shown, the assembly includes a mobile cart 1, a cylinder 2, a moving plate 3, a dust cover 4, a connecting pipe 5, a fixed support frame 6, a rotating column 7, a saw blade 8, a weight block 9, a first pulley 10, a first motor 11, a second pulley 12, a connecting belt 13, and a switching assembly. The cylinder 2 is connected to the upper left side of the mobile cart 1. The mobile cart 1 is equipped with a handrail for support. The moving plate 3 is connected to the telescopic end of the cylinder 2, and the moving plate 3 is slidably connected to the mobile cart 1. A dust cover 4 is connected to the lower side of the moving plate 3, and a connecting pipe 5 is connected to the upper part of the moving plate 3. The connecting pipe 5 connects to the dust cover 4. The dust cover 4 is connected to the lower middle part of the movable plate 3, and two fixed support frames 6 are connected to the front and rear. A rotating column 7 is rotatably connected between the fixed support frames 6. A saw blade 8 is connected to the rotating column 7 and is located inside the dust cover 4. A weight block 9 is connected to the rear side of the rotating column 7 and a first pulley 10 is connected to the front side of the rotating column 7. A first motor 11 is connected to the upper left side of the movable plate 3. A second pulley 12 is connected to the output shaft of the first motor 11. Three connecting belts 13 are wound between the second pulley 12 and the first pulley 10. A switching component is provided on the movable plate 3.

[0031] like Figures 1-4As shown, the switching assembly includes a second motor 38, a fixed rotating frame 39, a third motor 40, a chainsaw 41, and a distance sensor 42. The second motor 38 is connected to the front right side of the moving plate 3. The fixed rotating frame 39 is connected to the output shaft of the second motor 38. The fixed rotating frame 39 is rotatably connected to the moving plate 3. The third motor 40 is connected to the rear side of the fixed rotating frame 39. The chainsaw 41 is mounted on the fixed rotating frame 39. The output shaft of the third motor 40 is connected to the chainsaw 41. The distance sensor 42 is connected to the lower right side of the moving plate 3.

[0032] When using this invention, the operator first pushes the mobile vehicle 1 to move on the road where grooving is required. The processor starts the cylinder 2 through the control module to push the moving plate 3 to move. The height of the saw blade 8 is adjusted according to the required grooving depth. When grooving, the processor starts the first motor 11 through the control module to drive the second pulley 12 to rotate, so that the first pulley 10 and the connecting belt 13 rotate, thereby causing the rotating column 7 and the saw blade 8 to rotate and perform grooving operations on the road. The weight block 9 is used to maintain the balance of the rotating column 7, and the dust cover 4 is used to prevent dust from spreading. When trenching is required in the soil, cylinder 2 is activated to move the saw blade 8 away from the ground. Then, the second motor 38 is activated to rotate the fixed rotating frame 39, bringing the chainsaw 41 closer to the soil. At the same time, the third motor 40 is activated to drive the chainsaw 41 to operate, making the chainsaw 41 trench the soil. When encountering stones during the trenching process, the chainsaw 41 cannot continue to advance the trench. At this time, the distance sensor 42 detects that the distance between the chainsaw and the ground is stationary. Then, the chainsaw 41 is controlled to move away from the ground and the saw blade 8 moves closer to the ground. The saw blade 8 breaks the stones in the soil, thus enabling the rapid switching of the breaking function according to the site conditions to meet the flexible needs of complex construction scenarios.

[0033] like Figures 1-5As shown, it also includes a vacuuming assembly, which includes a connecting support frame 14, docking posts 15, connecting discs 16, connecting hollow posts 17, air inlet pipes 170, air outlet pipes 171, a moving post 18, a connecting rod 19, a collection bucket 20, a filter screen 21, a connecting cover 22, and a first connecting hose 23. Connecting support frames 14 are connected to both the front and rear sides of the middle of the moving plate 3. The lower part of each connecting support frame 14 is rotatably connected to a docking post 15, which is connected to the rotating post 7. A connecting disc 16 is connected to the side of each docking post 15 that is furthest from each other. A connecting hollow post 17 is connected to the upper side of each connecting support frame 14, and an air inlet pipe 170 is connected to the upper side of each connecting hollow post 17. The upper left side of the connecting hollow post 17... Each side is connected to an air outlet pipe 171. Both the air inlet pipe 170 and the air outlet pipe 171 are equipped with one-way valves to facilitate control of the direction of air in and out. The lower side of the hollow column 17 is slidably connected to a movable column 18. The lower side of the movable column 18 is rotatably connected to a connecting rod 19. The connecting rod 19 is rotatably connected to the adjacent connecting plate 16. The upper side of the middle of the movable plate 3 is connected to two collection buckets 20 by bolts.

The connecting cover 22 is connected to the connecting pipe 5. The air inlet pipe 170 is connected to a first connecting hose 23. The first connecting hose 23 is snapped into the adjacent collection bucket 20.

[0034] Using the dust collection component of this device, dust generated during the grooving process can be removed. When the rotating column 7 rotates, it drives the docking column 15 and the connecting plate 16 to rotate, causing the connecting rod 19 to push the moving column 18 up and down. When the moving column 18 moves downward, a negative pressure is generated inside the connecting hollow column 17. The dust inside the dust cover 4 is sucked into the collection bucket 20 through the air inlet pipe 170, the first connecting hose 23, the connecting cover 22, and the connecting pipe 5. The filter screen 21 intercepts the dust in the collection bucket 20, thereby removing the dust generated during the grooving process and reducing the impact of dust on surrounding personnel. When it is necessary to clean the dust intercepted in the collection bucket 20, the collection bucket 20 can be disassembled for cleaning.

[0035] like Figures 1-4 As shown, it also includes an air blowing assembly, which includes a first nozzle pipe 24 and a second connecting hose 25. The first nozzle pipe 24 is connected to the lower left side of the mobile vehicle 1. The second connecting hose 25 is connected to both the front and rear sides of the first nozzle pipe 24. The second connecting hose 25 is connected to the adjacent air outlet pipe 171.

[0036] Using the air blowing assembly of this device, residual dust and gravel in the trough can be removed. When the moving column 18 moves upward, it pushes gas from the air outlet pipe 171 and the second connecting hose 25 into the first nozzle pipe 24, so that the first nozzle pipe 24 sprays air into the opened trough, thereby removing residual dust and gravel in the trough to facilitate subsequent construction.

[0037] like Figure 1 and Figure 6 As shown, it also includes auxiliary components, including a first guide connecting frame 26, an elastic element and rollers 28. The first guide connecting frame 26 is slidably connected to the lower side of the connecting support frame 14. The first guide connecting frame 26 is connected to the connecting support frame 14 with an elastic element, which is a spring 27. Rollers 28 are rotatably connected to the first guide connecting frame 26.

[0038] Using the auxiliary components of this device can improve the stability of the connecting support frame 14. The force of the spring 27 ensures that the roller 28 on the first guide connecting frame 26 always keeps in contact with the ground, thereby supporting the connecting support frame 14, maintaining the structural stability of the connecting support frame 14, and avoiding the impact of vibration during slotting on the structural stability of the connecting support frame 14.

[0039] like Figure 1 and Figure 7 As shown, it also includes a dust suppression assembly, which includes a second guide connecting frame 29, a connecting column 30, a connecting fixing frame 31, a docking connector 32, a second nozzle pipe 33, a storage tank 34, a connecting pipe 35, a connecting pump 36, and a third connecting hose 37. Two connecting columns 30 are connected to the lower left side of the mobile vehicle 1, and the second guide connecting frame 29 is connected between the lower sides of the connecting columns 30. The connecting fixing frame 31 is connected to the lower middle part of the second guide connecting frame 29, and the docking connector 32 is connected to the upper left side of the connecting fixing frame 31. A second nozzle pipe 33 is connected to the lower left side of the fixed frame 31. The second nozzle pipe 33 is connected to the docking connector 32. A storage tank 34 is connected to the upper left side of the mobile vehicle 1. A docking pipe 35 is connected to the lower side of the storage tank 34. A connecting pump 36 is installed on the docking pipe 35. The mobile vehicle 1, cylinder 2, first motor 11, connecting pump 36, second motor 38, third motor 40, distance sensor 42 and processor are electrically connected through a control module. A third connecting hose 37 is connected to the lower side of the docking pipe 35. The third connecting hose 37 is connected to the docking connector 32.

[0040] Using the dust suppression components of this device can reduce dust rising during the grooving process. Water is poured into the storage tank 34. When grooving, the connecting pump 36 is started to send the water in the storage tank 34 from the connecting pipe 35, the third connecting hose 37, and the connecting head 32 into the second nozzle pipe 33, so that the second nozzle pipe 33 sprays water to suppress dust in the surrounding area, thereby reducing dust rising during the grooving process and reducing dust interference. The connecting fixing bracket 31 can shield and protect the second nozzle pipe 33.
