The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0018] like Figure 1-4 A road construction seam cutting device shown in the figure comprises a seam cutting wheel 1 that can be lifted up and down and a connecting member that drives the seam cutting wheel 1 to be lifted up and down, the connecting member being connected to both sides of the seam cutting wheel 1, a driving member being installed at the end of one side of the connecting member, the driving member being used to drive the seam cutting wheel 1 to rotate during the lifting process, an equipment cover 2 being provided on the outside of the seam cutting wheel 1, the connecting member, the driving member and the seam cutting wheel 1 being all located inside the equipment cover 2, the top ends of the connecting member and the driving member being installed on the top of the equipment cover 2, and the seam cutting wheel 1 being lifted up and down inside the equipment cover 2 through the connecting member and the driving member.

[0019] On the basis of the above, the slitting wheel 1 is suspended in the inner cavity of the equipment outer cover 2 through a connecting member and a driving member. The connecting member is used to drive the slitting wheel 1 to move up and down in the equipment outer cover 2, and the driving member drives the slitting wheel 1 to rotate to achieve slitting treatment of the road surface.

[0020] The connecting part includes a rotating shaft 3 fixed to the middle part of the side of the slitting wheel 1, a bearing 4 is sleeved on the outside of the rotating shaft 3, a connecting rod 5 extending upward is fixed on the outer wall of the bearing 4, and a sleeve 6 extending upward is sleeved on the outside of the top end of the connecting rod 5, and the top end of the sleeve 6 is fixed to the top of the inner cavity of the equipment cover 2.

[0021] Both sides of the entire slitting wheel 1 are inserted into the two bearings 4 through the rotating shaft 3 and rotate in the bearings 4. The connecting rod 5 is connected to the sleeve 6, so that the bearing 4 can be raised and lowered under the sleeve 6 through the connecting rod 5 and drive the slitting wheel 1 to adjust its height.

[0022] A return spring 7 is also sleeved on the outside of the connecting rod 5, the top end of the return spring 7 is fixed to the bottom end of the sleeve 6 and the bottom end is fixed to the outer wall of the bearing 4, the rotating shaft 3 in one of the connecting parts extends a distance to the outside of the bearing 4, and the driving part is connected to the end of the rotating shaft 3 extending outward.

[0023] The return spring 7 provides limiting and buffering for the lifting and lowering activities of the rotating shaft 3 and the connecting rod 5, so that the lifting and lowering activities of the slitting wheel 1 are smoother and more stable, thereby improving the effect of the road surface slitting treatment.

[0024] The driving member includes a prismatic rod 8 parallel to the connecting rod 5, and a prismatic tube 9 with lifting and lowering motion is sleeved on the bottom end of the prismatic rod 8. A crown tooth 10 is installed at the bottom end of the prismatic tube 9, and the crown tooth 10 is meshed with a gear 11. The gear 11 is fixed to the end of the rotating shaft 3 extending outward.

[0025] A servo motor 12 and a servo push rod 13 are installed on the top of the equipment outer cover 2. The output shaft of the servo motor 12 passes through the equipment outer cover 2 downward and is connected to the top of the prismatic rod 8. The output shaft of the servo push rod 13 passes through the equipment outer cover 2 downward and is fixedly connected to the outer wall of the bearing 4 in the connecting piece.

[0026] On the basis of the above, when the servo motor 12 is working, it will drive the prism rod 8 to rotate, and the prism rod 8 drives the crown tooth 10 at the bottom end of the prism tube 9 to engage with the gear 11 at the end of the rotating shaft 3, thereby driving the rotating shaft 3 to rotate in the bearing 4, so that the slitting wheel 1 on the rotating shaft 3 rotates in the equipment outer cover 2.

[0027] A water tank 14 is provided on one side of the equipment housing 2, and an equipment bottom plate 15 is fixed at the bottom of the water tank 14 and the equipment housing 2. A cutting groove 16 is provided on the equipment bottom plate 15. The cutting groove 16 is located directly below the slitting wheel 1, and the cutting wheel moves up and down in the cutting groove 16.

[0028] Furthermore, the slitting wheel 1 extends to below the equipment bottom plate 15 through the cutting groove 16. When the slitting wheel 1 is driven and rotated by the servo motor 12, the bottom end of the slitting wheel 1 acts on the road surface to perform the slitting operation.

[0029] Furthermore, the slitting wheel 1 can be raised and lowered, and the height of its bottom end can be adjusted by raising and lowering in the slitting groove, so that the slitting wheel 1 can act on the road surface to cut, specifically:

[0030] The two sides of the slitting wheel 1 are suspended inside the equipment cover 2 through the rotating shaft 3, bearing 4, connecting rod 5 and sleeve 6. When the slitting wheel 1 needs to be raised or lowered, the servo push rod 13 is used to push the bearing 4 in the connecting piece on one side to move downward, thereby driving the rotating shaft 3 in the bearing 4 to move downward, so that the slitting wheel 1 at the end of the rotating shaft 3 moves downward in the slitting groove to complete the height adjustment of the slitting wheel 1. In this process, the prism tube 9 and the crown tooth 10 are also moved downward due to gravity as the rotating shaft 3 and the gear 11 descend, so that the crown tooth 10 and the gear 11 remain in a meshing state, ensuring that the transmission state between the prism tube 9 and the rotating shaft 3 will not be disconnected, and the rotating shaft 3 can continue to be driven to rotate in the bearing 4 to complete the driving of the slitting wheel 1.

[0031] Furthermore, in order to ensure that the prism tube 9 can move up and down with the lifting and lowering of the rotating shaft 3 and the slitting wheel 1, so that the crown tooth 10 and the gear 11 remain in a meshing state, a fixing rod is connected between the prism tube 9 and the bearing 4, so that the lifting and lowering activities of the prism tube 9 and the bearing 4 remain consistent, thereby stabilizing the meshing state between the crown tooth 10 and the gear 11.

[0032] On the basis of the above, the slitting wheel 1 can be raised and lowered to the inside of the equipment cover 2. When the equipment is idle, the slitting wheel 1 can be folded up and provided with protection, so that it is not easy to collide with the outside and be damaged during transportation and movement, thereby ensuring the integrity and service life of the slitting equipment and improving its practicality.

[0033] A pressure pump 17 is installed on the top of the water tank 14, and the output end of the pressure pump 17 is connected to a water supply pipe 18 that bends and extends to both sides. The end of the water supply pipe 18 bends and extends to the bottom of the equipment bottom plate 15. A nozzle 19 is installed at the end of the water supply pipe 18 located below the equipment bottom plate 15. The nozzle 19 is located on both sides of the slitting wheel 1.

[0034] On the basis of the above, when the seam cutting wheel 1 is performing the seam cutting operation, the pressure pump 17 can be used to transport the water in the water tank 14 from the water supply pipe 18 to the nozzle 19 and spray it on the seam cutting of the road surface to reduce dust and flying sand splashed during the seam cutting operation.

[0035] Among them, a heating pipe 20 is installed on the top of the water tank 14, and the heating pipe 20 extends to the inside of the water tank 14. Because road cutting is done outdoors, the water body can be heated by the heating pipe 20 when the temperature is low in winter to prevent the water body from freezing. Universal wheels 22 are installed at the four corners of the bottom of the equipment base plate 15, and a handle 21 is installed at the edge of the equipment base plate 15. The handle 21 is used to push the equipment base plate 15 to move the universal wheels 22 at the bottom, thereby realizing the promotion of the entire equipment.

[0036] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
