[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-4 An edge-cutting device for asphalt construction includes a body 1 with multiple wheels 11 at the lower end of the body 1. The device is characterized in that a support arm 2 is rotatably mounted on one side of the body 1, and a disc-shaped edge-cutting blade 3 is rotatably mounted on the lower part of the support arm 2. The body 1 is provided with a drive assembly for driving the edge-cutting blade 3 to rotate. The edge-cutting blade is driven to rotate by the drive assembly to cut off the edge of the asphalt pavement.

[0027] The inner side of the support arm 2 is provided with a fixed shaft 21, and the machine body 1 is provided with a supporting bushing 22 that is rotatably connected to the fixed shaft 21. The lower part of the support arm 2 is fitted with a stabilizing sleeve 30 that is fitted on the outside of the rotating shaft of the cutting blade 3. The supporting bushing 22 supports the fixed shaft 21, and the fixed shaft 21 also supports the support arm 2 and the cutting blade 3, ensuring the stability of the cutting blade 3 during cutting. The stabilizing sleeve 30 supports the cutting blade 3, ensuring the stable rotation of the cutting blade 3 and ensuring the cutting effect.

[0028] The upper part of the support arm 2 is equipped with a control rod 24. The control rod 24 extends into the machine body 1 and is rotatably connected to the telescopic end of the electric cylinder 25. The fixed end of the electric cylinder 25 is rotatably installed on the inner bottom wall of the machine body 1. The electric cylinder 25, in conjunction with the control rod 24, drives the support arm 2 to rotate. When the electric cylinder 25 extends, it drives the support arm 2 to rotate downward, pressing down the cutting blade 3. Conversely, it lifts up the cutting blade 3, which facilitates the adjustment of the cutting depth of the cutting blade 3 according to the cutting depth requirements of different road surfaces, ensuring the cutting effect. At the same time, it can also be easily lifted and removed when the cutting blade is stuck, making it convenient for cutting construction.

[0029] Based on the above technical solution, when using this equipment to cut irregular edges of asphalt pavement, the extension and retraction of the electric cylinder 25 drives the support arm 2 to rotate, adjusting the height of the cutting blade 3 to a suitable level. Then, the drive assembly drives the cutting blade 3 to rotate, and the movement of the machine body 1 moves the cutting blade 3 to cut the pavement edge. The real-time adjustable height of the cutting blade 3 ensures adaptability to pavement edges of different heights and effectively prevents the cutting blade 3 from getting stuck, guaranteeing a good cutting effect.

[0030] In this technical solution, such as Figure 1-6As shown, the drive assembly includes a first sprocket 31 coaxially connected to the cutting blade 3, a second sprocket 32 ​​connected to the first sprocket 31 via a chain 311, a driven gear 33 coaxially and fixedly connected to the second sprocket 32, a driving gear 34 meshing with the driven gear 33, and a drive motor 35 for driving the driving gear 34. The second sprocket 32 ​​and the driven gear 33 are both rotatably mounted on the outside of the fixed shaft 21, and the drive motor 35 is fixedly installed in the machine body 1. The design of the second sprocket 32 ​​and the driven gear 33 mounted on the outside of the fixed shaft 21 ensures a good transmission effect for the cutting blade 3, unaffected by the rotation of the support arm 2. The number of teeth on the driven gear 33 should be greater than the number of teeth on the driving gear 34 to ensure the rotational torque of the cutting blade 3 and the effective cutting of the asphalt pavement.

[0031] In this technical solution, such as Figure 1-6 As shown, the inner side of the fixed shaft 21 extends out of the supporting bushing 22 and is fixedly connected to a counterweight 23. The design of the counterweight 23 ensures that the two sides of the support arm 2 are kept as balanced as possible, guaranteeing good stability when the cutting blade 3 is cutting the edge, and ensuring safe construction of asphalt pavement edge cutting.

[0032] In this technical solution, such as Figure 1-6 As shown, an arc-shaped stabilizing groove 26 with the axis of the fixed shaft 21 as its center is embedded on the side wall of the machine body 1 corresponding to the outer side of the control rod 24. This ensures the stability of the control rod 24 during movement and guarantees good control over the depth of the cutting blade 3.

[0033] In this technical solution, such as Figure 1-6 As shown, the machine body 1 is equipped with a travel motor for driving the wheels 11 and a control box 4 electrically connected to the travel motor, drive motor 35, and electric cylinder 25. During edge cutting, the travel motor drives the machine body 1 to move, facilitating the edge cutting process. The control box 4 is located on the side of the machine body 1 away from the support arm 2. This improves the even distribution of weight on both sides of the machine body 1, ensuring stability during the cutting of asphalt pavement.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
