Description

Technical Field

[0002] Road construction is a complex and comprehensive engineering process, involving various stages from planning, design to construction and maintenance. After a road has been used for a long time, it will cause cracks in the road surface due to temperature changes, traffic loads and road aging. Timely repair of cracks can prevent the cracks from expanding and extend the service life of the road surface. By using a caulking machine, hot asphalt or other sealing materials can be poured into the cracks to form a sealing layer, which can effectively prevent water and impurities from entering the cracks, thereby avoiding further damage to the cracks due to low temperatures in winter or vehicle loads.

When the frame 1 moves forward, the transmission shaft 1507 can drive the scraper 1506 to rotate synchronously, and the asphalt in the collecting barrel 1501 is scraped toward the feed port 1509 and enters the collecting box 1508 for collection. When the wheel 1412 rotates, the waste collecting box 1510 can be vacuumed through the first one-way valve 1414, and the asphalt in the collecting box 1508 is sucked into the waste collecting box 1510 through the third one-way valve 1511 for centralized collection.

[0054] Specifically, the working principle of this road construction device is as follows: when in use, when the motor 13 drives the first rotating shaft 7 to rotate, it can drive the second rotating shaft 1401 to rotate synchronously, and clean the ground through the cleaning disc 1406 and the bristles 1407, and under the action of the third spring 1405, the cleaning disc 1406 is driven to be close to the ground to ensure the cleaning quality; at the same time, the first rotating shaft 7 drives the rotating wheel 1412 to rotate synchronously, thereby driving the driving frame 1411 through the eccentric shaft 1413 to drive the piston 1409 to move back and forth, so that the first one-way valve 1414 and the second one-way valve 1415 are alternately turned on, and air is injected into the nozzle 1416, and sprayed onto the road surface from the nozzle 1417, so as to further remove dust and ensure the quality of grouting.

[0055] The guide wheel 4 is placed in the gap, and the guide wheel 4 will deflect along the path of the gap, thereby automatically adjusting the direction of the frame 1, and the gap detection block 610 is inserted into the gap. During the movement of the frame 1, under the action of the first spring 604, the gap detection block 610 is always in contact with the bottom of the gap. When the gap is deeper, the gap detection block 610 and the telescopic rod 603 move downward, and the number of through grooves 606 connected to the material distribution groove 605 increases, thereby increasing the injection flow of the nozzle 608, ensuring that the gap is fully filled and improving the filling quality.

[0056] The overflowed asphalt can be scraped into the collecting barrel 1501 through the scraper 1503. When the frame 1 moves forward, the transmission shaft 1507 can drive the third rotating shaft 1505 and the scraper 1506 to rotate synchronously, so that the asphalt in the collecting barrel 1501 is scraped toward the feed port 1509 and enters the collecting box 1508 for collection. When the wheel 1412 rotates, the waste collecting box 1510 can be vacuumed through the first one-way valve 1414, and the asphalt in the collecting box 1508 is sucked into the waste collecting box 1510 for centralized collection through the third one-way valve 1511, which is convenient for use and avoids the overflowed asphalt from polluting the road surface.

[0057] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
