[0002] The main function of the road surface is to bear the wheel load and the weight transferred by the road structure layer. Among them, asphalt pavement is a more common road surface. Asphalt pavement refers to various types of pavements paved with road asphalt materials mixed into mineral materials, which improves the ability of paving aggregates to resist damage to the road surface caused by driving and natural factors. Asphalt pavement will be affected by various natural and human factors during use, such as vehicle load, temperature changes, rain erosion, etc., resulting in cracks, potholes, rutting and other damage to the road surface. Asphalt repair equipment is usually used to repair the road surface. Among them, asphalt repair rake is a commonly used professional tool in asphalt pavement repair construction. It can evenly spread the asphalt mixture on the road surface area that needs to be repaired.
[0003] The problem with the existing technology is that when an asphalt repair rake is used to pave an asphalt pavement, the rake teeth of the rake body may wear out after long-term use. If the rake body is not replaced in time, the severely worn rake body may not be able to evenly spread the asphalt mixture, affecting the repair quality of the asphalt pavement. Utility Model Content

[0022] like Figures 1 to 4 As shown, an asphalt road repair device provided by an embodiment of the present invention includes a rake plate 1, a rake handle 2, a fixed block 3, a fixed groove 4 and a connecting structure 5.

[0023] refer to Figure 2 and Figure 4 The connecting structure 5 includes a moving block 8, which is arranged on the top of the fixed block 3. The outer surface of the moving block 8 is slidably connected to the inner wall of the moving groove 7. The top of the moving block 8 is fixedly connected to the pushing block 9, and the bottom of the moving block 8 is fixedly connected to the moving arm 10.
[0024] The above solution is adopted: by setting the moving block 8, when the pushing block 9 is pushed to the left, it can drive the moving block 8 to slide to the left in the moving groove 7, thereby synchronously driving the moving arm 10 to move to the left.
[0025] refer to Figure 4 The movable arm 10 is arranged on the inner wall of the fixed groove 4, the top of the movable arm 10 is fixedly connected to the bottom of the movable block 8, the front and rear ends of the bottom of the movable arm 10 are respectively fixedly connected with pressure rods 11, and two rotating arms 12 are respectively provided on the left sides of the two pressure rods 11.
[0026] The above solution is adopted: by setting up the movable arm 10, the movable arm 10 can be driven by the movable block 8 to move right in the fixed groove 4, and at the same time drive the movement of the two pressure rods 11 respectively, so that the two pressure rods 11 can respectively drive the relative rotation of the two rotating arms 12.
[0027] refer to Figure 4The two rotating arms 12 are both arranged on the inner wall of the fixed groove 4, and the rotating arms 12 are staggered up and down. The sides of the two rotating arms 12 away from each other are respectively fitted with the outer surfaces of the two pressure rods 11, and the ends of the two rotating arms 12 away from each other are rotatably connected to the inner wall of the fixed groove 4 through a rotating shaft. The left sides of the two rotating arms 12 are respectively fixedly connected with a linkage arm 13.
[0028] The above solution is adopted: by setting the rotating arms 12, the two pressure rods 11 can press the surfaces of the two rotating arms 12 while moving, so that the two rotating arms 12 can rotate relative to each other and be staggered up and down, thereby driving the rotation of the two linkage arms 13 respectively.
[0029] refer to Figure 4 The right ends of the two linkage arms 13 are fixedly connected to the ends of the two rotating arms 12 away from each other. The surfaces of the two linkage arms 13 are respectively provided with linkage grooves 14. The inner walls of the two linkage grooves 14 are respectively sleeved with linkage rods 15.

The two positioning springs 17 are respectively sleeved on the outer surface of the positioning rod 401, and the left sides of the two locking arms 16 are respectively fixedly connected with locking blocks 18.
[0032] The above solution is adopted: by setting the locking arms 16, the two locking arms 16 can be driven by the linkage rod 15 respectively, slide away on the surface of the positioning rod 401, and squeeze the compression of the two positioning springs 17 respectively.

[0034] The above solution is adopted: by providing the blocking blocks 18, the two blocking blocks 18 can be separated from the mounting grooves 601 when moving away, thereby releasing the fixed limit of the mounting block 6, thereby releasing the fixed connection between the rake plate 1 and the rake handle 2.
[0035] The working principle of this utility model:
[0036] When the rake plate 1 is in use, it is moved close to the fixed block 3 and the mounting block 6 is aligned and inserted into the fixed groove 4. The mounting block 6 moves and squeezes the movement of the two blocking blocks 18 at the same time, driving the two blocking arms 16 to slide away from the surface of the positioning rod 401. When the mounting block 6 is fully inserted into the fixed groove 4, the two positioning springs 17 push the two blocking arms 16 to slide, and then drive the two blocking blocks 18 to move close and respectively insert them into the mounting grooves 601 to fix the mounting block 6, thereby fixing the rake plate 1 to the fixed block 3 and completing the fixed connection between the rake plate 1 and the rake handle 2. Subsequently, the construction workers can hold the rake handle 2 to control the rake plate 1 and evenly pave the repaired asphalt through the rake teeth 101. When the rake plate 1 needs to be replaced for repair work, the pushing block 9 can be pushed to the left to drive the moving block 8 to move. When the two levers 14 are in the same position, the two levers 14 move in a reverse direction, and the two levers 15 move in a reverse direction, so that the levers 14 move in a reverse direction, and the levers 14 move in a reverse direction, so that the levers 14 move in a reverse direction, and the levers 14 move in a reverse direction, so that the levers 14 move in a reverse direction, and the levers 14 move in a reverse direction, so that the levers 14 move in a reverse direction, and the levers 14 move in a reverse direction, so that the levers 14 move in a reverse direction, and the levers 14 move in a reverse direction, so that the levers 14 move in a reverse direction, and the levers 14 move in a reverse direction,
[0037] In summary, the asphalt road repair device, through the coordinated operation of the rake plate 1, the rake handle 2, the fixing block 3, the fixing groove 4 and the connecting structure 5, solves the problem that when an asphalt repair rake is used to pave an asphalt road, the rake body may wear out after long-term use. If the rake body is not replaced in time, the severely worn rake body may not be able to evenly spread the asphalt mixture, thereby affecting the repair quality of the asphalt road surface.
