The spray head 56 is arranged toward the ground, and the soft The pipe 54 and the clamping plate 59 both pass through the opening 11. Under the action of the water pump 52, the water in the water tank 51 enters the shunt pipe 55 through the connecting water pipe 53 and the hose 54 in turn, and is finally sprayed out through the nozzle 56. The nozzle 56 is set toward the ground to ensure that the water spray is evenly distributed on the surface of the roadbed that needs to be compacted, thereby improving the compaction effect and work efficiency, and effectively reducing the dust on the construction site and improving the working environment. The combined design of the support frame 58, the clamping plate 59 and the spring 591 provides a stable suspension and buffer mechanism for the spray assembly 5, which is convenient for reducing the impact of vibration on the spray system, increasing the durability and reliability of the equipment, and facilitating the disassembly of the shunt pipe 55.

[0026] A friction pad is movably connected to the inner side of the clamping block 510. The friction pad is a component made of rubber material. The friction pad is in contact with the outer surface of the shunt tube 55. The rubber material has a high friction coefficient. When the friction pad is in contact with the outer surface of the shunt tube 55, it is easy to provide a strong friction force to ensure that the shunt tube 55 maintains a stable position during the movement of the trolley 1, reducing the risk of displacement or loosening.

[0027] The top of the first groove 12 is provided with an adjustment component 7 for adjusting the height of the shunt tube 55. The adjustment component 7 includes a fixing plate 71 fixedly connected to the top of the first groove 12, a second groove 72 opened on one side of the fixing plate 71, a threaded rod 73 arranged inside the second groove 72, a motor 74 fixedly connected to the top of the fixing plate 71, and a first slider 75 threadedly connected to the outer surface of the threaded rod 73. The first slider 75 is fixedly connected to the mounting frame 57, one end of the threaded rod 73 is rotatably connected to the inner wall of the second groove 72, the other end of the threaded rod 73 passes through the second groove 72 and is fixedly connected to the output end of the motor 74, and the threaded rod 73 is driven to rotate by the motor 74, so that the first slider 75 threadedly connected to the threaded rod 73 moves up and down accordingly, thereby realizing the adjustment of the height of the shunt tube 55, facilitating the shunt tube 55 to be moved to the top of the frame 2 for disassembly, and the disassembled shunt tube 55 can be conveniently cleaned by hand by the first pressure roller 3 and the second pressure roller 61.

The sliding connection of the second slider 751 in the slide groove 721 provides a parallel guide rail for the up and down movement of the first slider 75, thereby ensuring the linear movement of the first slider 75 during the adjustment process.

[0029] A first pressing roller 3 is provided at one end of the frame 2 away from the trolley 1, and a first rotating shaft 31 is rotatably connected between the first pressing roller 3 and the frame 2. A support plate 6 is fixedly connected to the bottom end of the frame 2, and a second pressing roller 61 is provided on the inner side of the support plate 6. A second rotating shaft 62 is rotatably connected between the second pressing roller 61 and the support plate 6. During the forward movement of the trolley 1, the second pressing roller 61 performs preliminary compaction on the surface of the roadbed, and the first pressing roller 3 further increases the squeezing effect on the roadbed material. The coordinated work of the two facilitates enhancing the overall compaction effect and helps to form a denser and more stable roadbed.

[0030] A connecting plate 4 is movably provided at the top of the frame 2, and a scraper 41 is fixedly connected to one end of the connecting plate 4. A locking bolt 42 is threadedly connected between the connecting plate 4 and the frame 2, and the scraper 41 is in contact with the outer surface of the first pressure roller 3. The design of the scraper 41 in contact with the outer surface of the first pressure roller 3 makes it easy to effectively remove residual materials such as mud and gravel adhering to the surface of the pressure roller when it is working. Since the locking bolt 42 is threadedly connected between the connecting plate 4 and the frame 2, it is easy to disassemble the scraper 41 for cleaning.

[0031] When in use, start the water pump 52. Under the action of the water pump 52, the water in the water tank 51 enters the shunt pipe 55 through the connecting water pipe 53 and the hose 54 in turn, and is finally sprayed out through the nozzle 56. The nozzle 56 is set toward the ground to ensure that the water spray is evenly distributed on the surface of the roadbed that needs to be compacted, thereby improving the compaction effect and working efficiency. At the same time, it effectively reduces the dust on the construction site and improves the working environment. Start the trolley 1. During the forward movement of the trolley 1, the second pressure roller 61 performs preliminary compaction on the surface of the roadbed, and the first pressure roller 3 further increases the squeezing effect on the roadbed material. The coordinated work of the two facilitates to enhance the overall compaction effect, which helps to form a more dense and stable roadbed. 58. The combined design of the clamping plate 59 and the spring 591 provides a stable suspension and buffer mechanism for the spray assembly 5, which is convenient for reducing the impact of vibration on the spray system. The design of the scraper 41 in contact with the outer surface of the first pressure roller 3 is convenient for effectively removing residual materials such as soil and gravel adhering to the surface of the first pressure roller 3 when the first pressure roller 3 is working. After compaction, the threaded rod 73 is driven to rotate by the motor 74, so that the first slider 75 threadedly connected to the threaded rod 73 moves up and down accordingly, thereby realizing the adjustment of the height of the shunt pipe 55, facilitating the shunt pipe 55 to be moved to the top of the frame 2 for disassembly. The disassembled shunt pipe 55 can be conveniently cleaned by hand by the first pressure roller 3 and the second pressure roller 61.
