Description

Technical Field

[0001] The utility model belongs to the technical field of road maintenance, in particular to a rolling device with a material discharge structure for asphalt road maintenance. Background Art

[0002] Asphalt road maintenance refers to the process of repairing or renovating damaged or aged asphalt pavement, aiming to restore its functionality, smoothness, and service life. Asphalt road maintenance typically includes various operations, such as crack repair, pothole filling, rutting repair, and pavement reinforcement. These maintenance operations effectively prevent further road damage and improve driving safety and comfort.

[0003] When repairing asphalt roads, the paving thickness is usually determined by the depth of the damaged area. The degree of road damage in different areas is also different, and the paving thickness of the asphalt needs to be adjusted at any time. However, it is difficult to adjust the paving thickness of the asphalt in the existing asphalt paving device, resulting in asphalt waste or repeated paving during the paving process, which is not convenient to use. For this reason, we propose a rolling device with a discharge structure for asphalt road repair. Summary of the Invention

[0004] The purpose of the utility model is to provide a rolling device with a discharge structure for asphalt road maintenance. The first motor drives the threaded rod to rotate, which can move the first slider, thereby moving the push rod, the fixed rod and the baffle, changing the size of the opening between the two baffles, and solving the problem that the existing asphalt paving device is difficult to adjust the paving thickness of the asphalt, resulting in asphalt waste or the need for repeated paving during the paving process.

[0008] Through the above technical solution, the operation of the first motor drives the threaded rod to rotate. Since the fixed rod limits the push rod, the push rod limits the first slider, so that the slider rotates along the threaded rod.

[0009] Furthermore, a rolling mechanism is provided under the base plate, and the rolling mechanism includes a mounting frame fixedly connected to the bottom of the base plate, a sliding rod fixedly connected to the bottom of the base plate, and an end of the sliding rod away from the base plate is fixedly connected to the bottom wall inside the mounting frame.

[0014] Through the above technical solution, the second motor can drive the pressing roller to rotate, so that the pressing roller can move along the asphalt road and squeeze the asphalt road.

[0015] Furthermore, a cleaning mechanism is provided inside the U-shaped frame, and the cleaning mechanism includes a telescopic rod fixedly connected to the top wall inside the U-shaped frame, a scraper fixedly connected to the bottom end of the telescopic rod, the side of the scraper away from the telescopic rod contacts the outer wall of the pressure roller, and the side of the scraper close to the telescopic rod is fixedly connected to a second spring.

[0017] Through the above technical solution, the stability of the scraper can be improved by the telescopic rod, and the cleaning effect of the scraper can be improved by the elastic force of the second spring.

[0018] The utility model has the following beneficial effects:

[0019] 1. The utility model is provided with a discharge mechanism. The operation of the first motor drives the threaded rod to rotate. The rotation of the threaded rod can make the first slider move along the threaded rod. The movement of the first slider drives the push rod to move. The end of the push rod away from the first slider drives the fixed rod to move. The movement of the fixed rod drives the baffle to rotate around the connection point with the discharge pipe, so that the opening size between the two baffles changes, thereby changing the paving thickness of the asphalt, so as to facilitate the repair of different damaged areas and roads of different depths.

[0020] 2. The utility model is provided with a rolling mechanism, which starts the contraction of the hydraulic rod. The contraction of the hydraulic rod will pull the fixed plate downward, and the fixed plate will move downward, and the connecting rod will drive the third slider to move downward. Because the second slider and the U-shaped frame are fixed together, and the asphalt road will block the pressure roller, the first spring will be compressed when the third slider descends, and the reaction force of the first spring will exert a downward force on the second slider, and the second slider will apply a force to the U-shaped frame, and the U-shaped frame will apply a force to the pressure roller, thereby increasing the pressure between the pressure roller and the asphalt road, reducing the gaps in the asphalt, and improving the overall quality of the road.

[0021] 3. The utility model is provided with a cleaning mechanism. The second spring is in a compressed state when installed. The elasticity of the second spring will push the scraper to move downward. The second spring can improve the stability of the scraper when moving, so that the scraper and the pressure roller always keep in contact. When the pressure roller rotates, the scraper can remove the asphalt adhering to the pressure roller, thereby avoiding excessive accumulation of asphalt on the pressure roller, resulting in the pressure roller being unable to apply pressure evenly and making the road surface uneven.

[0036] A specific application of this embodiment is:

[0037] When the staff needs to use the equipment, they add asphalt into the discharge box 201 and then start the first motor 204. The operation of the first motor 204 drives the threaded rod 205 to rotate. The rotation of the threaded rod 205 can make the first slider 207 move along the threaded rod 205. The movement of the first slider 207 drives the push rod 208 to move, and the end of the push rod 208 away from the first slider 207 drives the fixed rod 209 to move.

The thickness of the asphalt paving changes, thereby changing the thickness of the asphalt, so as to facilitate the repair of roads with different damaged areas and different depths. When the pressure roller 311 contacts the asphalt road, the second slider 303 will be at a certain distance from the bottom wall of the mounting frame 301, and then the hydraulic rod 308 will be activated to retract. The contraction of the hydraulic rod 308 will pull the fixed plate 307 downward, and the fixed plate 307 drives 06 downward, and the connecting rod 306 drives the third slider 305 downward. Because the second slider 303 and the U-shaped frame 309 are fixed together, and the asphalt road will block the pressure roller 311, the asphalt road will block the pressure roller 311. , so that when the third slider 305 descends, the first spring 304 is compressed, and the reaction force of the first spring 304 exerts a downward force on the second slider 303, and the second slider 303 exerts a force on the U-shaped frame 309, and the U-shaped frame 309 exerts a force on the pressure roller 311, thereby increasing the pressure between the pressure roller 311 and the asphalt road, reducing the gaps in the asphalt, and improving the overall quality of the road. Then, the second motor 310 is started, and the operation of the second motor 310 drives the pressure roller 311 to rotate, so that the device moves forward and squeezes the asphalt road. When the pressure roller 311 squeezes the asphalt road During the extrusion process, since the asphalt has a certain viscosity, it will adhere to the pressure roller 311. The second spring 403 is in a compressed state when installed. The elasticity of the second spring 403 will push the scraper 402 to move downward. The second spring 403 can improve the stability of the scraper 402 when moving, so that the scraper 402 and the pressure roller 311 always maintain contact. When the pressure roller 311 rotates, the scraper 402 can remove the asphalt adhering to the pressure roller 311, thereby preventing the pressure roller 311 from accumulating too much asphalt, resulting in the pressure roller 311 being unable to apply pressure evenly, making the road surface uneven.
