[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0030] The present embodiment provides a polishing asphalt grinding disc grooving device 1, comprising a shell 12, a clamping shell 13 and a grooving mold 14, the shell 12 comprises an inner cylinder 121 and an outer cylinder 122 which are arranged mutually, a gap is provided between the inner cylinder 121 and the outer cylinder 122, the tops of the inner cylinder 121 and the outer cylinder 122 are connected by a top cover 123, the top cover 123 extends radially inward from the top of the outer cylinder 122 and connects with the top of the inner cylinder 121, the bottoms of the inner cylinder 121 and the outer cylinder 122 are open structures, the clamping shell 13 is inserted into the gap from the bottom of the shell 12, the grinding disc 2 to be grooved is detachably mounted on the lower opening of the clamping shell 13, the grinding disc 2 comprises a grinding disc body 21 and asphalt 22 arranged on the lower surface of the grinding disc body, the grooving mold 14 is arranged below the grinding disc 2, the shell 12 is pressed toward the grooving mold 14, so that the grooving mold 14 is pressed into the surface of the asphalt 22 to achieve grooving.

[0031] Specifically, in this embodiment, the slotting die 14 is a grid structure, and the grid can be in various shapes such as quadrilateral, pentagon, hexagon, etc.

[0032] Specifically, in this embodiment, the inner cylinder 121 and the outer cylinder 122 are coaxially arranged.

[0033] Specifically, in this embodiment, the inner cylinder 121 and the outer cylinder 122 are both cylindrical, and the top cover 123 is annular.

[0034] Specifically, in this embodiment, the inner cylinder 121, the outer cylinder 122 and the top cover 123 are integrally formed.

[0035] Specifically, in this embodiment, before the slotting mold 14 is pressed into the surface of the asphalt 22, the asphalt 22 needs to be heated to soften the surface of the asphalt 22 so that the slotting mold 14 can be smoothly pressed into the surface of the asphalt 22 to achieve slotting.

[0036] Specifically, in this embodiment, a guide groove 124 is provided on the inner wall of the outer cylinder 122, and a stopper 131 is provided on the outer wall of the clamping shell 13. The stopper 131 slides in the guide groove 124. The stopper 131 is a square, and the side length of the square is the width of the guide groove 124. The guide groove 124 includes a mounting groove 1241 vertically provided upward along the bottom of the outer cylinder 122, an anti-slip groove 1242 vertical to the mounting groove 1241, and a sliding groove 1243 parallel to the mounting groove 1241. The anti-slip groove 1242 is connected to the mounting groove 1241 and the sliding groove 1243 respectively. The length of the mounting groove 1241 is greater than its width, such as Figure 2 As shown, the length of the installation groove 1241 is L and the width is L′, which satisfies: L>L′. Similarly, the length of the anti-slip groove 1242 is also greater than its width, which can ensure that the block 131 can smoothly pass through the two right-angle corners formed by the installation groove 1241 and the anti-slip groove 1242, and the anti-slip groove 1242 and the sliding groove 1243. When the clamping shell 13 is installed, the block 131 is aligned with the installation groove 1241 at the bottom of the outer cylinder 122, and is installed upward along the installation groove 1241, smoothly passing through the installation groove 1241, the anti-slip groove 1242 and two right-angle corners to reach the sliding groove 1243. When the polishing asphalt grinding disc grooving device 1 is used for grooving, the block 131 always slides in the sliding groove 1243. More specifically, after the block 131 enters the guide groove 124, a structure such as a wooden plug (not shown in the figure) can be used to block the installation groove 1241, so that the block 131 is not easy to slip out during the sliding process in the guide groove 124.

[0037] Specifically, in this embodiment, the top of the clamping shell 13 is provided with an extension part that fits the inner cylinder 121. The relative position between the clamping shell 13 and the shell 12 can be ensured, and the stopper 131 is controlled in the guide groove 124 so that the stopper 131 slides in the guide groove 124. More specifically, the extension part of the clamping shell 13 fits tightly with the inner cylinder 121. When the clamping shell 13 slides relative to the shell 12, the extension part of the clamping shell 13 and the stopper 131 cooperate with the inner cylinder 121 and the outer cylinder 122 of the shell 12 respectively to play a guiding role, so that the shell 12 is pressed downward in a direction perpendicular to the grinding disc body 21.

[0038] Specifically, in this embodiment, the inner wall of the clamping shell 13 is closely matched with the grinding disc 2 to guide the movement of the grinding disc 2 .

[0039] Specifically, in the present embodiment, the top end of the clamping shell 13 is in contact with the lower surface of the top cover 123 via the elastic portion 15. The elastic portion 15 is disposed in the gap between the inner cylinder 121 and the outer cylinder 122. In the initial state, the length of the elastic portion 15 is greater than the distance from the bottom surface of the inner cylinder 121 to the upper surface of the grinding disc body 21. When the shell 12 presses the grinding disc body 21 downward, the asphalt 22 is pressed into the slotting mold 14 to achieve slotting of the grinding disc 2. After slotting is achieved, the elastic portion 15 can use its elastic restoring force to push the clamping shell 13 back to its initial position, thereby achieving automatic resetting of the polishing asphalt grinding disc slotting device 1. Generally, the elastic portion 15 can be set as a spring. As Figure 1 As shown, in the initial state of the elastic portion 15, the length from the top of the clamping shell 13 to the lower surface of the top cover 123 is L1, and the distance from the bottom surface of the inner cylinder 121 to the upper surface of the grinding disc body 21 is L2, satisfying L1>L2.

[0040] Specifically, in this embodiment, the number of the elastic part 15 is greater than or equal to 1, and more specifically, it can be set as a spring, the diameter of which is greater than the diameter of the inner cylinder 121 and smaller than the diameter of the outer cylinder 122, and can be smoothly placed in the gap formed by the inner cylinder 121 and the outer cylinder 122, so as to be located between the clamping shell 13 and the top cover 123. The elastic part 15 can also be set as two or more springs, the diameters of which are smaller than the size of the gap formed by the inner cylinder 121 and the outer cylinder 122, and these springs are symmetrically placed in the gap formed by the inner cylinder 121 and the outer cylinder 122.

[0041] Specifically, in this embodiment, the bottom of the shell 12, the upper and lower surfaces of the grinding disc 2 and the surface of the slotting mold 14 are parallel to each other. More specifically, the thickness of the grinding disc body 21 is the same at all positions, and the asphalt 22 is poured on the surface of the grinding disc body 21, and the thickness of the poured asphalt 22 is also the same everywhere, that is, the lower surface of the shell 12, the surface of the grinding disc body 21, the surface of the asphalt 22 and the surface of the slotting mold 14 are parallel to each other.

[0042] Specifically, in this embodiment, when slotting, the shell 12 is pressed manually, and the elastic part 15 is compressed to apply elastic force to the clamping shell 13, so that the clamping shell 13 is pressed against the surface of the slotting mold 14, and the shell 12 is pressed downward continuously, and the inner cylinder 121 contacts the grinding disc 2 and applies pressure to the grinding disc 2, so that the pre-heated asphalt on the grinding disc 2 is pressed into the slotting mold 14, and the slotting is completed. Since the clamping shell 13 is closely guided and matched with the inner cylinder and outer cylinder of the shell 12, the inner cylinder 121 of the shell 12 presses the surface of the grinding disc, and the grinding disc is closely guided and matched with the inner wall of the clamping shell 13, it can be ensured that the grinding disc 2 is subjected to uniformly distributed force, and since the lower surface of the shell 12, the surface of the grinding disc body 21, the surface of the asphalt 22 and the surface of the slotting mold 14, these four surfaces are parallel to each other, the asphalt on the lower surface of the grinding disc 2 can be evenly pressed into the slotting mold, so that the depth and width of the slotting are consistent on the entire surface of the asphalt 22, ensuring the consistency and accuracy of the slotting, and achieving high-quality slotting.

[0043] Specifically, in this embodiment, the device also includes a handle 11, which is inserted into the inner cylinder 121 from the center of the top cover 123. The length of the handle 11 is greater than the depth of the inner cylinder 121, so that the handle 11 can completely push the grinding disc 2 out of the clamping shell 13.

[0044] The above specific implementations do not constitute a limitation on the protection scope of the present utility model. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
