Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 4 , the following technical solutions are provided in this embodiment:

[0024] As Figures 1 - 3 shown, a crack repair device includes: a trolley board 1, a connecting arm 101 is fixedly installed on the upper surface of one end of the trolley board 1, a handle 102 is fixedly installed at one end of the connecting arm 101, a locking disc 202 is fixedly installed on the upper surface of the trolley board 1, a filling bucket 2 is fixedly installed on the upper surface of the locking disc 202, a discharge pipe 201 is connected and installed at one end of the filling bucket 2, the discharge pipe 201 penetrates to the lower surface of the trolley board 1, a partition mechanism 4 is slidably installed in the discharge pipe 201, and the control end of the partition mechanism 4 is fixedly installed on the outer surface of the handle 102.

[0025] A fan 3 is fixedly installed on the upper surface of the trolley board 1, the air outlet of the fan 3 is connected and installed with a horizontal air nozzle 301, and the horizontal air nozzle 301 penetrates to the lower surface of the trolley board 1 and is inclined.

[0026] An L-shaped elastic piece 103 is fixedly installed on the lower surface of the trolley board 1, and a V-shaped scraping piece 104 is fixedly installed at one end of the L-shaped elastic piece 103.

[0027] Through the design of the trolley board 1, V-shaped scraper 104, filling material bucket 2, discharge pipe 201, fan 3, horizontal air nozzle 301 and partition mechanism 4, during use, the staff can move the trolley board 1 to above the crack by pushing, and then start the fan 3 and pull the partition mechanism 4. The started fan 3 can blow out the dust and garbage in the lower gap through the horizontal air nozzle 301, which can quickly clean the working area. This step is completed before filling, which can ensure that there are no sundries in the crack and avoid affecting the adhesion effect of the filling material. The pulled partition mechanism 4 can connect the discharge pipe 201 with the filling material bucket 2, so that the filling material in the filling material bucket 2 can be discharged from the discharge pipe 201 into the blown gap. As the staff continues to push, the V-shaped scraper 104 arranged on the lower surface of the trolley board 1 can fully scrape the discharged filling material into the gap and scrape the filling material flat. After pushing to the end of the gap, the staff can loosen the partition mechanism 4. After the partition mechanism 4 is not pulled by an external force, it can automatically reset to block and partition the discharge pipe 201 to prevent the filling material from flowing out of the filling material bucket 2, so as to enable the staff to accurately control the outflow of the filling material, reduce waste, and the automatic reset function reduces the complexity of the operation.

[0028] As Figure 4 shown, the partition mechanism 4 includes a connecting plate 401. A connecting column 403 is slidably installed in the connecting plate 401. One end of the connecting column 403 is fixedly installed with an isolation plate 402, and the isolation plate 402 can block and seal the discharge pipe 201;

[0029] Among them, a communication port 408 is opened at one end of the upper surface of the isolation plate 402. When the isolation plate 402 drives the communication port 408 to slide to be flush with the pipe orifice of the discharge pipe 201, the filling material bucket 2 can discharge the crack filling material through the discharge pipe 201.

[0030] A spring 404 is arranged in the connecting column 403, and both ends of the spring 404 are respectively fixedly connected to one end inside the connecting plate 401 and one end inside the connecting column 403.

[0031] The other end of the isolation plate 402 is fixedly connected with a steel wire rope. The steel wire rope fixedly connected to one end of the isolation plate 402 slides through the guide pipe 405. The guide pipe 405 is fixedly installed on the upper surface of the trolley board 1, and the other end of the guide pipe 405 penetrates into the connecting arm 101 and is connected to the docking handle 406. The docking handle 406 is fixedly installed on the outer surface of the grip handle 102. A pulling handle 407 is rotatably installed in the docking handle 406, and the pulling handle 407 is fixedly connected with the steel wire rope sliding out of the guide pipe 405.

[0032] Through the design of the isolation plate 402, connecting column 403, spring 404, guide tube 405, docking handle 406 and pulling handle 407, when the staff holds the outer surface of the handle 102 to push the trolley plate 1, the pulling handle 407 can be rotated within the docking handle 406 by pinching. Then, the pulling handle 407 can pull the steel wire rope in the guide tube 405. The tensioned steel wire rope will pull the isolation plate 402 to drive the connecting column 403 to slide out of the connecting plate 401. When the connecting column 403 is pulled, the internally fixedly connected spring 404 will also be pulled. The spring 404 can apply a reset elastic force to the connecting column 403 and the isolation plate 402. At the same time, the isolation plate 402 will also drive the communication port 408 opened on the upper surface to be flush with the nozzle of the discharge pipe 201. Then, the filling material in the filling bucket 2 can enter the discharge pipe 201 through the communication port 408, and the filling material can flow along the discharge pipe 201 into the gap on the road surface for filling and repair. After pushing to the end of the gap, the staff can release the pulling handle 407. The released pulling handle 407 can relieve the tension on the steel wire rope, and the isolation plate 402 can block the nozzle of the discharge pipe 201 through the reset tension of the spring 404 to prevent the filling material from flowing out of the filling bucket 2. Then, the staff can precisely control the outflow and stop of the filling material by pinching the pulling handle 407. This design enables the operator to conveniently control the flow rate of the filling material, avoid waste, and reduce the loss of the filling material in non-essential areas.

[0033] Summarize and sort out the working steps of this solution according to the above technical solution: After the staff holds the outer surface of the handle 102 and moves the trolley plate 1 above the crack, the fan 3 and the kneading and pulling handle 407 can be started. The started fan 3 can blow out the dust and garbage in the lower gap through the horizontal nozzle 301, which can quickly clean the working area. This step is completed before filling, which can ensure that there is no debris in the crack and avoid affecting the adhesion effect of the filling material. The kneaded pulling handle 407 will rotate in the docking handle 406, and then the pulling handle 407 can pull the steel wire rope in the guiding tube 405. The tensioned steel wire rope will pull the isolation plate 402 to drive the connecting column 403 to slide out of the connecting plate 401. When the connecting column 403 is pulled, the internally fixedly connected spring 404 will also be pulled. The spring 404 can apply a reset elastic force to the connecting column 403 and the isolation plate 402. At the same time, the isolation plate 402 will also drive the communication port 408 opened on the upper surface to be flush with the nozzle of the discharge pipe 201. Then, the filling material in the filling material bucket 2 can enter the discharge pipe 201 through the communication port 408, and the filling material can flow along the discharge pipe 201 into the gap of the road surface for filling and repairing. With the continuous pushing of the staff, the V-shaped scraper 104 provided on the lower surface of the trolley plate 1 can scrape the discharged filling material into the gap and level the filling material. After pushing to the end of the gap, the staff can release the pulling handle 407. The released pulling handle 407 can relieve the tension applied to the steel wire rope, and the isolation plate 402 can block the nozzle of the discharge pipe 201 through the reset tension of the spring 404 to avoid the outflow of the filling material from the filling material bucket 2. Thus, the staff can accurately control the outflow of the filling material, reduce waste, and the automatic reset function reduces the complexity of the operation.

[0034] In summary: The device enables the staff to accurately control the outflow and stop of the filling material by kneading the pulling handle 407. This design allows the operator to conveniently control the flow rate of the filling material, avoid waste, and reduce the loss of the filling material in non-necessary areas.
