[0028] Specifically, when the discharge head 12 needs to be replaced during operation of the crack repair machine, first, the operator moves the moving rod 15 by pulling the handle 16, and as the moving rod 15 moves, the externally fixed moving block 13 also moves synchronously. During this process, the externally fixed insertion block 17 on the right gradually pulls the insertion block 17 out of the clamping slot 18 as the moving block 13 moves. At this time, the movement of the insertion block 17 will exert a pressing action on the return spring 14, and as the return spring 14 is deformed by external force, the internal elastic force gradually accumulates. When the insertion block 17 is completely separated from the clamping slot 18, the discharge head 12 can be easily removed from the outside of the conveying pipe 11 for replacement or maintenance. After the old discharge head 12 is removed, it is also very convenient to install a new discharge head 12. The operator only needs to align the new discharge head 12 with the bottom of the conveying pipe 11 and insert it into the outside of the conveying pipe 11. Next, release the handle 16. At this time, the return spring 14 will push the insertion block 17 back into the clamping slot 18 through its reaction force, ensuring that the discharge head 12 is securely fixed to the conveying pipe 11. In this way, the replacement process of the entire discharge head 12 is successfully completed, ensuring the firmness and safety of the discharge head 12 after installation. Compared with the traditional discharge head 12 replacement method, which requires tedious operations such as manually using a wrench to loosen or tighten the bolts, this method does not require the use of any tools, is simple and convenient to operate, saves time and effort, and greatly improves the working efficiency of the crack repair machine.

[0029] With reference to Figure 2 , Figure 3 and Figure 5 , the cleaning assembly 22 comprises a second motor 2201 arranged at the lower part of the mounting frame 20, and a first transmission wheel 2202 fixedly connected to the output end of the second motor 2201. The first transmission wheel 2202 is rotatably connected inside the mounting frame 20, and a transmission rod 2205 is rotatably connected to the right side inside the mounting frame 20. The transmission rod 2205 is fixedly connected with a second transmission wheel 2204 outside, and the first transmission wheel 2202 is connected with the second transmission wheel 2204 through a transmission belt 2203. The bottom of the transmission rod 2205 is fixedly connected with an electric push rod 2206, and the output end of the electric push rod 2206 is fixedly connected with a circular cleaning brush 2207. The electric push rod 2206 is arranged to facilitate the adjustment of the position of the circular cleaning brush 2207. The lower part of the mounting frame 20 is fixedly connected with a fixed ring 21, and the second motor 2201 is fixedly connected inside the fixed ring 21. The fixed ring 21 is arranged to facilitate the fixation of the second motor 2201.

[0030] Specifically, during the crack repair process, first, the construction personnel easily move the frame 1 of the crack repair machine to the crack position that needs to be repaired through the cooperation of the handrail 3 and the roller 2. When the frame 1 moves to above the crack, the operator can start the electric push rod 2206, and the electric push rod 2206 drives the circular cleaning brush 2207 fixed at the output end to start moving, so that the circular cleaning brush 2207 extends to the crack surface. Next, the second motor 2201 is started, and the second motor 2201 drives the first transmission wheel 2202 at its output end to start rotating. Through the transmission belt 2203, the rotational motion of the first transmission wheel 2202 is transmitted to the second transmission wheel 2204, so that the second transmission wheel 2204 starts to rotate synchronously. During the rotation of the second transmission wheel 2204, the internal fixed transmission rod 2205 also rotates accordingly, and the rotation of the transmission rod 2205 drives the electric push rod 2206 fixed at the bottom to rotate, thereby driving its output end The fixed circular cleaning brush 2207 rotates. As the circular cleaning brush 2207 rotates, dust, sand and other impurities on the surface and inside of the crack are effectively cleaned. The circular cleaning brush 2207 is made of flexible and wear-resistant material, which can penetrate deep into the crack and remove impurities attached therein without causing secondary damage to the crack. During the cleaning process, the rotation of the brush head can ensure that every part of the crack is cleaned evenly, especially for small cracks. The efficient rotation of the brush head can thoroughly remove the dirt on its surface. By cleaning the cracks, the dust, impurities and moisture in the cracks are thoroughly cleaned, thereby improving the adhesion effect of the repair agent and ensuring that the repair material can better penetrate and adhere to the crack surface. At the same time, it also avoids the peeling problem between the repair agent and the crack surface due to impurities. The crack surface after cleaning has a higher adhesion ability, and the repair agent can be evenly filled in the crack without leaving any gaps, forming a more solid repair layer.

[0031] Working principle: When using the crack repair machine, when the discharging head 12 needs to be replaced, first, pull the handle 16 to move the moving rod 15, and the moving rod 15 moves and moves the external fixed moving block 13, and the moving block 13 moves and moves the external right fixed plug block 17, and at the same time squeezes the return spring 14, so that the return spring 14 is deformed by the force, and when the plug block 17 is out of the groove 18, the discharging head 12 can be removed from the outside of the conveying pipe 11 for replacement. During installation, the new discharging head 12 is stuck into the bottom of the conveying pipe 11, and then, the handle 16 is released, and the plug block 17 is inserted into the groove 18 under the reaction force of the return spring 14 to complete the installation of the discharging head 12, which makes it easy to replace the discharging head 12 of the crack repair machine, and solves the traditional replacement method of manually loosening or tightening the bolts by a wrench. This method is simple and convenient to operate, saves time and effort, and improves the working efficiency of the crack repair machine.

[0032] When repairing a crack, first, the frame 1 is moved to the crack that needs to be repaired by cooperating with the handrail 3 and the roller 2. At this time, the electric push rod 2206 is started to move the circular cleaning brush 2207 fixed at the output end, so that the circular cleaning brush 2207 moves and extends to the crack. Subsequently, the second motor 2201 is started, and the second motor 2201 drives the first transmission wheel 2202 fixed at the output end to rotate. The first transmission wheel 2202 rotates and drives the second transmission wheel 2204 to rotate through the transmission belt 2203. When the second transmission wheel 2204 rotates, it drives the internal fixed transmission rod 2206. 05Inside the mounting frame 20, when the transmission rod 2205 rotates, the electric push rod 2206 fixed at the bottom rotates, and the electric push rod 2206 rotates and the circular cleaning brush 2207 fixed at the output end rotates. The rotation of the circular cleaning brush 2207 can clean the dust and impurities attached to the cracks, so that when repairing the cracks, it is convenient to clean the impurities and dust attached to the cracks, the repair agent can better adhere to the crack surface, enhance the repair effect, avoid the repair agent from peeling off from the crack surface, extend the durability of the repair, and improve the service life of the road surface.
