Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a road crack repairing device. Background Art

[0002] When cracks appear on the road surface after long-term use, it is necessary to use a crack repair device to fill the cracks with sealant for repair. After searching, the Chinese patent publication number CN113585030B discloses a crack filling device for repairing asphalt pavement cracks. The device is designed with a fixing device to ensure that the filling is completed smoothly and the filling will not be unable to be carried out due to inaccessibility. However, when the device is repairing, if the surface of the crack on the ground is very dry, the adhesion of the repair material will be reduced, resulting in poor repair effect, and air bubbles may be formed between the sealant and the crack surface, affecting the sealing effect. Utility Model Content

[0003] In response to the deficiencies of the prior art, the present invention provides a road crack repair device, which solves the problem in the background art that when the surface of the road crack is very dry, the adhesion of the repair material is reduced, resulting in poor repair effect.

[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a road crack repair device, including a device body, a material trough, a connecting arm and a guide trough, a material bin is installed on the top of the device body, a sealing cover is provided on the top of the material bin, a roller is installed at the bottom of the device body, a handle is welded at one end of the device body, one side of the handle is welded to one end of the connecting rod, the other end of the connecting rod is welded to one end of the material trough, a guide trough is welded at the other end of the material trough, one end of the top of the guide trough is welded to one side of the device body, a discharge valve is provided on the top of one end of the guide trough, the discharge valve is communicated with the interior of the material bin, an atomizing nozzle is installed at the bottom of the guide trough, a plurality of atomizing nozzles are provided, and the plurality of atomizing nozzles are communicated with each other, the atomizing nozzle is communicated with one end of a water pump through a pipe, the other end of the water pump is communicated with the interior of a water tank, the water tank is welded to one side of the material bin, and a water inlet is provided on the top of the water tank.

[0005] Preferably, columns are welded on both sides of the material trough, one end of the top of the column is rotatably connected to one end of the electric telescopic rod, the electric telescopic rod is arranged in an inclined shape, and the other end of the electric telescopic rod is rotatably connected to the middle part of the connecting arm. The telescopic end of the electric telescopic rod is contracted, so that the connecting arm can be rotated upward, and the brush wheel can be lifted upward for recovery.

[0006] Preferably, one end of the connecting arm is rotatably connected to the side of the material trough, and the other end of the connecting arm is installed with a driving motor by a screw. A brush wheel is mounted on the outside of the output end of the driving motor, and the surface of the brush wheel is a brush. Driven by the driving motor, the brush wheel can clean the dust in the crack, thereby improving the bonding effect between the sealant and the crack.

[0007] Preferably, the bottom and top of the trough are open, and the bottom of the trough is flush with the bottom of the roller, so that when too much sealant is discharged from the guide trough, the excess sealant can be stored inside the trough, and the excess sealant inside can slowly seep downward by moving the trough on the crack surface.

[0008] Preferably, a scraper is welded to one end of the material trough, and the scraper has an inclined structure. As the material trough moves on the crack surface, the scraper at one end can scrape excess sealant on the crack surface into the inside of the material trough, thereby keeping the crack surface smooth.

[0009] The utility model provides a road crack repair device with the following beneficial effects:

[0010] (1) A road crack repair device, when in use, can pump water from the water tank into the nozzle through a water pump, so that the atomizing nozzle can spray the water on the ground to cool it down, and by opening the discharge valve, the sealant inside the material bin can be discharged through the discharge valve, and then flow into the material trough through the guide groove. When the material trough moves to the crack surface, the sealant inside the material trough will penetrate into the crack to repair it. By spraying water to moisten the crack surface, it helps to improve the bonding effect of the repair material and ensure the stability and durability after the repair. At the same time, spraying water can reduce the generation of air bubbles and ensure that the sealant is in full contact with the crack surface.

[0011] (2) The pavement crack repair device extends the telescopic end of the electric telescopic rod, which drives the rotating arm to rotate. The rotating arm drives the brush wheel to move downward while rotating. The brush wheel is driven by the driving motor to clean the dust in the crack, thereby improving the bonding effect between the sealant and the crack.

[0012] This solves the problem that when the surface of the ground crack is very dry during repair by the existing device, the adhesion of the repair material is reduced, resulting in poor repair effect. BRIEF DESCRIPTION OF THE DRAWINGS

When the rotating arm rotates, it can drive the brush wheel 12 to move downward, and then the brush wheel 12 is driven by the driving motor 11 to clean the dust in the crack, and then the water inside the water tank 17 can be pumped into the nozzle through the water pump 16, so that the atomizing nozzle 15 can spray the ground to cool it down. By opening the discharge valve 14, the sealant inside the material bin 2 can be discharged through the discharge valve 14, and then flow into the material trough 7 through the guide groove 13. When the material trough 7 moves to the crack surface, the sealant inside the material trough 7 will penetrate into the crack for repair. The crack surface is moistened by spraying water, which helps to improve the bonding effect of the repair material and ensure the stability and durability after repair. At the same time, the dust during cleaning by the brush wheel 12 can be reduced by spraying.
