The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0030] As Figures 1 to 8 shown, a road maintenance slotting machine includes a substrate 1. A slot 2 is formed in the middle of the substrate 1. Slide rails 3 are fixedly connected to both sides of the slot 2. A protective frame 4 is slidably connected between the slide rails 3. A cutting wheel 5 is rotatably connected inside the protective frame 4. A movable protective plate 6 is rotatably connected to the rear side of the protective frame 4.

[0031] Embodiment 1: The movable protective plate 6 is arc-shaped. The shape of the movable protective plate 6 is adapted to the shape of the rear opening of the protective frame 4. A torsion spring 7 is sleeved in the middle of the rotating shaft of the movable protective plate 6. The torsion of the torsion spring 7 causes the movable protective plate 6 to tilt upward. By providing the movable protective plate 6 with a torsion spring 7 at the rear side of the protective frame 4, when the device adjusts the position to align with the slotting position, the movable protective plate 6 automatically tilts under the action of the torsion spring 7, which is convenient for the operator to directly observe the aligned position of the cutting wheel 5, making the cutting position adjustment of the slotting machine more convenient. After completing the position alignment, pressing down the movable protective plate 6 can make it merge with the rear opening of the protective frame 4, so as to fully cover and protect the outside of the cutting wheel 5, and pressing down the protective plate 6 can apply a force to the road surface to improve the stability of the device during slotting.

[0032] Embodiment 2: A tension spring 8 is fixedly connected to the top of the chute of the slide rail 3. The end of the tension spring 8 is fixedly connected to the slider on the protective frame 4. The pulling force of the two tension springs 8 is greater than the total gravity of the protective frame 4 and the cutting wheel 5. When the tension spring 8 contracts, the bottom height of the cutting wheel 5 is higher than the bottom height of the substrate 1. By arranging the tension spring 8 in the slide rail 3, when grooving processing is not carried out, the tension spring 8 can lift the cutting components such as the cutting wheel 5 to avoid affecting the position adjustment of the device. When grooving processing is carried out, it is necessary to press the movable protective plate 6 to merge it with the protective frame 4, and at the same time apply a downward force to lower the height of the cutting wheel 5 to contact the road surface for grooving cutting.

[0033] Embodiment 3: The bottom of the slide rail 3 is inclined forward. A foot pedal 9 is fixedly connected to the rear side of the movable protective plate 6. The foot pedal surface of the foot pedal 9 is perpendicular to the sliding direction of the slide rail 3. By arranging the foot pedal 9 on the rear side of the movable protective plate 6, when grooving processing is carried out, directly step on the foot pedal 9 to apply a downward force, and the movable protective plate 6 can be merged with the protective frame 4. At the same time, the height of the protective frame 4 and the cutting wheel 5 can be lowered to cut the road surface. The slide rail 3 is set to an inclined state so that the acting force for cutting the road surface faces forward, which is convenient for the operator to step on the foot pedal 9 with one foot and push forward.

[0034] Embodiment 4: A driving motor is arranged on one side of the protective frame 4. The output end of the driving motor is coaxially and fixedly connected to the rotating shaft of the cutting wheel 5.

[0035] Embodiment 5: Two moving wheels 10 are rotatably connected to both sides of the substrate 1. The distance between the bottom of the moving wheel 10 and the bottom of the substrate 1 is less than three centimeters. By arranging the moving wheels 10 on both sides of the substrate 1, the grooving machine can adjust its position during grooving. Limiting the distance between the bottom of the moving wheel 10 and the bottom of the substrate 1 makes the center of gravity of the grooving machine lower, thereby improving the overall stability of the grooving machine.

[0036] Embodiment 6: A handrail 11 is fixedly connected to the rear side of the substrate 1. A control device is arranged on the handrail 11. The control device is electrically connected to the driving motor of the cutting wheel 5. By arranging the handrail 11 on the rear side of the substrate 1, it is convenient to control the overall moving direction of the grooving machine through the handrail 11, and the control device on the handrail 11 controls whether the cutting wheel 5 rotates and its rotation speed for grooving cutting.

[0037] The working principle of the present utility model is as follows:

[0038] S1. A movable protection plate 6 with a torsion spring 7 is arranged at the rear side of the protection frame 4. When the device adjusts its position to align with the grooving position, the movable protection plate 6 automatically tilts under the action of the torsion spring 7, which facilitates the operator to directly observe the alignment position of the cutting wheel 5, making it more convenient to adjust the cutting position of the grooving machine. After the position alignment is completed, pressing down the movable protection plate 6 can merge it with the opening at the rear side of the protection frame 4, enabling it to fully cover and protect the outside of the cutting wheel 5. Moreover, pressing down the protection plate 6 can exert a force on the road surface to improve the stability of the device during grooving.

[0039] S2. A tension spring 8 is arranged in the slide rail 3. When grooving processing is not carried out, the tension spring 8 can lift the cutting components such as the cutting wheel 5 to avoid affecting the position adjustment of the device. When grooving processing is carried out, it is necessary to press the movable protection plate 6 to merge it with the protection frame 4, and at the same time exert a downward force to lower the height of the cutting wheel 5 to contact the road surface for grooving and cutting.

[0041] 1. For this road maintenance grooving machine, by arranging a movable protection plate 6 with a torsion spring 7 at the rear side of the protection frame 4, when the device adjusts its position to align with the grooving position, the movable protection plate 6 automatically tilts under the action of the torsion spring 7, which facilitates the operator to directly observe the alignment position of the cutting wheel 5, making it more convenient to adjust the cutting position of the grooving machine. After the position alignment is completed, pressing down the movable protection plate 6 can merge it with the opening at the rear side of the protection frame 4, enabling it to fully cover and protect the outside of the cutting wheel 5. Moreover, pressing down the protection plate 6 can exert a force on the road surface to improve the stability of the device during grooving.

[0042] 2. For this road maintenance grooving machine, by arranging a tension spring 8 in the slide rail 3, when grooving processing is not carried out, the tension spring 8 can lift the cutting components such as the cutting wheel 5 to avoid affecting the position adjustment of the device. When grooving processing is carried out, it is necessary to press the movable protection plate 6 to merge it with the protection frame 4, and at the same time exert a downward force to lower the height of the cutting wheel 5 to contact the road surface for grooving and cutting. By arranging a foot pedal 9 at the rear side of the movable protection plate 6, when grooving processing is carried out, directly stepping on the foot pedal 9 to exert a downward force can merge the movable protection plate 6 with the protection frame 4, and at the same time lower the heights of the protection frame 4 and the cutting wheel 5 to cut the road surface. The slide rail 3 is set in an inclined state to make the force for cutting the road surface face forward, which is convenient for the operator to step on the foot pedal 9 with one foot and push forward.

[0043] 3. For this road maintenance grooving machine, by setting moving wheels 10 on both sides of the substrate 1, the grooving machine can adjust its position during grooving. By restricting the distance between the bottom of the moving wheels 10 and the bottom of the substrate 1, the center of gravity of the grooving machine is lowered, thereby improving the overall stability of the grooving machine.
