Description

Technical Field

[0001] This utility model relates to the field of highway maintenance technology, and in particular to a highway crack treatment device. Background Technology

[0002] Urban roads and highways paved with asphalt often develop numerous irregular cracks after long-term use or due to geographical conditions and heavy vehicles. If not repaired in time, rainwater will corrode various layers of the road, affecting the overall service life of the road. Regular filling of the cracks is necessary.

[0003] By comparing a highway crack treatment device with patent publication number CN220013328U, this solution uses a blower to disperse dust in the cracks, then re-injects asphalt into the cracks. After injection, a roller is used to flatten the asphalt, achieving an integrated operation. However, after the asphalt is used, residual asphalt may adhere to the inner wall of the caulking pipe. As the device moves, it will generate a certain vibration, which may cause the residual asphalt in the caulking pipe to overflow and adhere to the highway. This may leave small asphalt particles on the normal highway surface. When the asphalt solidifies, it may affect the smoothness of the highway surface, requiring subsequent cleaning, thus having certain limitations. Utility Model Content

[0028] In this embodiment, the filling mechanism includes a filling component for filling road cracks and a moving component for adjusting the filling position of the filling component.

[0029] The moving component includes a slide rail 201 located on the front side of the base frame 100, a lead screw 203 rotatably mounted inside the slide rail 201, a sliding seat 204 slidably mounted inside the slide rail 201, the sliding seat 204 being threadedly connected to the lead screw 203, and a moving motor 202 mounted on the rotating end of the lead screw 203.

[0030] The filling component includes a connecting plate 205 disposed on the upper end of the sliding seat 204. The connecting plate 205 is inverted L-shaped. A feeding hopper 207 is provided at the lower end of the connecting plate 205. A feeding hose 209 is installed at the lower end of the feeding hopper 207. The feeding hose 209 is threadedly connected to the feeding hopper 207 and is detachable. A pump body 206 is provided on the rear side of the connecting plate 205. A discharge pipe is connected between the pump body 206 and the feeding hopper 207. A feed pipe is connected between the pump body 206 and the mixing tank 302. A sealing component is provided at the feeding hose 209 for sealing the lower end of the feeding hose 209.

[0031] The sealing assembly includes a fixing plate 216 disposed on both sides of the feeding hopper 207. The fixing plate 216 is fixedly connected to the connecting plate 205. A cylinder 217 is provided at the lower end of the fixing plate 216. A clamping plate 218 is installed at the end of the cylinder 217 near the feeding hose 209. A control assembly for controlling the clamping plate 218 to clamp the feeding hose 209 is provided inside the feeding hopper 207.

[0032] The control components include fixed slots 210 on the front and rear side walls of the feeding hopper 207. Lifting seats 211 that can move up and down are slidably installed in the fixed slots 210. Feeding plates 208 are rotatably installed on one end of the two lifting seats 211 close to each other. The rotating end of the feeding plate 208 is connected to the lifting seat 211 by a torsion spring. A compression spring is connected between the bottom end of the lifting seat 211 and the fixed slot 210. A baffle 212 is fixed on the end of the lifting seat 211 close to the feeding plate 208. A top column 213 is fixed at the middle position of the upper end of the lifting seat 211. A button 215 is installed on the upper end of the fixed slot 210. A vibration component for driving the fixed slot 210 to vibrate is provided at the top column 213.

[0033] The vibration assembly includes striking columns 214 positioned on both sides of the top column 213. The striking columns 214 are slidably connected to the lifting seat 211, and a striking spring is connected between the striking columns 214 and the lifting seat 211. The pump body 206 draws the filling material into the discharge hose 209, and then adds it to the crack that needs to be filled. The movable assembly can better adapt to cracks of different lengths and widths. After the crack is filled, the sealing assembly clamps and seals the lower end of the discharge hose 209 to prevent the residual filling material on the inner wall of the discharge hose 209 from overflowing downwards. This reduces the impact of residual filling material overflow on the normal road surface and improves the cleanliness of the road surface.

[0034] Working principle: First, the filler material is added into the mixing tank 302. The stirring motor 303 drives the stirring blade 304 to rotate, which fully mixes the filler material inside. Then, the scraper 305 scrapes off the filler material adhering to the inner wall of the mixing tank 302.

[0035] Then, the drive motor 202 drives the lead screw 203 to rotate, which in turn drives the sliding seat 204 to move back and forth in the slide rail 201 to adjust the filling position of the discharge hose 209. Then, the pump body 206 is started to draw the filling material in the mixing tank 302 into the discharge bin 207. The filling material flows downward and impacts the two discharge plates 208 below, causing the two discharge plates 208 to rotate downward and open. This causes the two discharge plates 208 to drive the lifting seat 211 to move downward, so that the top column 213 releases the pressure on the button 215. This drives the two cylinders 217 to move the two clamping plates 218 away from each other, releasing the clamp on the lower end of the discharge hose 209. The filling material flows along the discharge hose 209 into the crack in the road. The baffle 212 can effectively prevent the filling material from flowing into the fixed groove 210.

[0036] After the crack is filled, the extraction of filling material stops, and the filling material no longer flows in the discharge bin 207. Then, the two lifting seats 211 quickly return to their original position using compression springs, causing the striking column 214 to move upward rapidly. This causes the striking column 214 to strike the upper end of the fixed groove 210, which in turn causes the fixed groove 210 to vibrate, thus causing the entire discharge bin 207 to vibrate. This vibrates the entire discharge hose 209, causing the remaining filling material on the discharge hose 209 and the inner wall of the discharge bin 207 to fall into the crack. After the two striking columns 214 strike the fixed groove 210, the lifting seats 211 continue to rise, causing the top column 213 to move upward and press the button 215. This causes the two cylinders 217 to once again drive the clamping plate 218 to clamp the lower end of the discharge hose 209, preventing the remaining filling material from overflowing downward. This reduces the impact of the remaining filling material overflowing on the normal road surface and improves the cleanliness of the road surface.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
