Description

Technical Field

[0001] The utility model relates to the technical field of road construction equipment, in particular to a road compacting device that prevents soil from sticking. Background Art

[0002] Road compaction refers to the use of rollers to pressurize the road surface again after the road is paved, so that the road surface layer can be compacted and the road surface strength can be improved. Among them, roller equipment is widely used. It is mainly composed of a moving mechanism of the power part and a roller assembly connected to its front side through a connecting arm. The roller moves on the road surface with the moving mechanism, pressing the roller on the ground, and the rolling roller compacts the road surface synchronously with the movement of the moving mechanism.

[0003] For example, a construction road compaction device with application number 202321011812.7, the two ends of the pressure roller of the device are movably connected to the two sides of the mounting frame, and a cutting knife assembly and a collecting box are respectively provided at the end of the mounting frame away from the pressure roller. The collecting box is located below the cutting knife assembly, and a scraper is fixedly connected to the top of the collecting box. A connecting plate is fixed to one side of the collecting box, one end of the traction assembly is installed on the top of the connecting plate, and an inclined plate is installed in the inner cavity of the collecting box. A discharge trough connected to the inner cavity of the collecting box is provided on one side of the mounting frame, and a scraper assembly for preventing soil blockage is installed in the discharge trough. When the pressure roller rotates, the cutting knife assembly will cut the soil on the surface of the pressure roller, and then the scraper on the top of the collecting box will scrape off the soil. The soil debris slides toward the discharge trough under the action of the inclined plate, and the discharge speed of the soil in the discharge trough is accelerated by starting the scraper assembly to prevent blockage. However, after analyzing the above-mentioned comparative patents and most of the existing road compacting devices, it was found that it is difficult to adjust the distance between the scraper and the roller in the road compacting device. When the roller is disassembled for maintenance, it is difficult to adjust to a better fitting position due to installation errors to achieve a better scraping effect.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a road compacting device that prevents soil from sticking is proposed. Utility Model Content

The front surfaces of both ends of the cross bar 5 are fixedly connected to the limiting rods 8. The upper surface of the outer frame 1 is fixedly connected to the limiting blocks 9, and the limiting rods 8 pass through and are slidably connected to the inside of the limiting blocks 9. When the roller 2 rolls forward to roll the road, the threaded rod 4 can be adjusted to rotate. Under the limiting action of the threaded seat 3, the cross bar 5 can slide on the upper surface of the outer frame 1 to adjust the scraper 6 to be close to the outer cylindrical surface of the roller 2. Due to the inclined design of the cross bar 5, the scraper 6 will scrape off the mud or debris stuck on the outer cylindrical surface of the roller 2 and gradually deliver it to both sides. When adjusting the sliding of the cross bar 5, the limiting rod 8 can slide inside the limiting blocks 9 to improve stability. This design is convenient for the operator to adjust the distance between the scraper 6 and the roller 2 by himself, so as to achieve a better fitting and scraping effect after replacing the roller 2.

[0022] like Figure 1 and Figure 4 As shown, the front and rear outer surfaces of the outer frame 1 are rotatably connected to a screw rod 10, the outer cylindrical surface of the screw rod 10 is threadedly connected to a nut seat 11, one side outer surface of the nut seat 11 is fixedly connected to a fixing block 12, and one end of the screw rod 10 is fixedly connected to a handwheel to facilitate the operator to rotate the screw rod 10.

[0023] Furthermore, a slot 13 is provided on the upper surface of the fixed block 12, and a collecting shell 14 is provided on the front surface of the fixed block 12. The collecting shell 14 is slidably connected to the upper surface of the outer frame 1 to perform auxiliary limiting to prevent the nut seat 11 from rotating.

[0025] Working principle: When using the road compaction device to prevent soil adhesion, first, before the roller 2 rolls forward to compact the road, the threaded rod 4 can be adjusted to rotate. Under the limiting action of the threaded seat 3, the cross bar 5 can slide on the upper surface of the outer frame 1, so as to adjust the scraper 6 to be close to the outer cylindrical surface of the roller 2. Due to the inclined design of the cross bar 5, the scraper 6 will scrape off the soil or debris adhered to the outer cylindrical surface of the roller 2 and gradually deliver it to both sides. When adjusting the sliding of the cross bar 5, the limit rod 8 can slide inside the limit block 9. The design facilitates the operator to adjust the distance between the scraper 6 and the roller 2 by himself, so as to achieve a better fit and scraping effect after replacing the roller 2.

The scraped soil or debris is collected by the collecting shell 14, and the block 15 can slide out from the upper surface of the card slot 13, and the collecting shell 14 can be disassembled and dumped. This is the working principle of the road compacting device to prevent soil adhesion.
