[0002] The dirt shoulder of a highway refers to the unpaved area on both sides of the highway pavement. Its main function is to provide space for emergency stops, emergency rescue, and traffic accident handling. It can also help share the road load and prevent wheels from straying from the lane. The dirt shoulder is usually composed of natural soil and is easily affected by factors such as rain erosion and vehicle traffic over a long period of time, which makes it prone to soil loss or erosion. By laying earth-building material on the dirt shoulder, the soil can be effectively prevented from being washed away or crushed by vehicles, maintaining the integrity of the shoulder and ensuring that the highway remains safe and in good operating condition during long-term use.

[0003] Traditional highway shoulder soiling methods usually rely on manual labor and simple machinery. Usually, a small loader or excavator is used to load the soil onto a transport vehicle, and then the soil is spread on the shoulder manually.

The connecting block 17 is rotatably connected to the inside of the skateboard 14. A support seat 19 is fixedly connected to one side of the skateboard 14. The function of the support seat 19 is to provide support for the other roller 6 so that the roller 6 can rotate freely in the support seat 19. The other roller 6 is rotatably connected to the inside of the support seat 19. A sliding rod 21 is fixedly connected to the other side of the skateboard 14, which cooperates with the slide groove 20 inside the support frame 4. The slide rod 21 is connected to the slide groove 20 by sliding, so that the skateboard 14 can move smoothly along the predetermined track in the support frame 4. A slide groove 20 is provided inside the support frame 4, and the slide rod 21 is slidably connected to the inside of the slide groove 20.

[0035] Specifically, during the conveying process of the conveyor belt 7, the scraper 13 inside the support frame 4 is tightly fitted to the surface of the conveyor belt 7, which can effectively scrape off the dust, debris and other pollutants remaining on the surface of the conveyor belt 7, ensuring the cleanliness of the conveyor belt 7 and avoiding the accumulation of materials affecting the conveying efficiency.

[0036] Working principle: When using the automatic soil-laying device for the shoulder of the highway, the soil is first loaded into several silos 3, and the distribution device is driven by the transport vehicle 1 to move along the shoulder. During the movement, the silo 3 is controlled to drop the contents onto the conveyor belt 7 at its bottom, and then the roller 6 is driven to rotate by the output end of the motor 5 so that the conveyor belt 7 on its outer wall begins to transport the soil. When the soil is transported to one side, it will fall into the lower hopper 10 on the side of the transport vehicle 1. At this time, the connecting rod 9 can be driven to rotate by the output end of the motor 2 8, so that the connecting rod 9 drives the lower hopper 10 connected to one side to extend and tilt on the side of the transport vehicle 1, thereby causing the soil to slide from the lower hopper 10 to the shoulder. By controlling the flow rate of the silo 3 and the rotation speed of the conveyor belt 7, the discharge amount can be flexibly adjusted, thereby achieving the effect of uniform distribution of soil on the shoulder, and in the process of transportation by the conveyor belt 7, the support The scraper 13 inside the frame 4 is fitted on the surface of the conveyor belt 7, thereby effectively scraping off the dust remaining on the surface of the conveyor belt 7. When the tension of the conveyor belt 7 needs to be adjusted, the knob 18 can be turned to force the screw 16 connected at one end to rotate inside the fixed block 15. The screw 16 is moved by the threaded relationship between the screw 16 and the fixed block 15, and the screw 16 pushes the connecting block 17 connected at one end to move. The connecting block 17 is forced to push the slide 14 of the outer wall to move. The slide 14 is forced to drive the sliding rod 21 connected on one side to slide in the slide groove 20 inside the support frame 4. At the same time, the slide 14 will also drive the support seat 19 on the other side to move, so that the support seat 19 drives one of the rollers 6 and the conveyor belt 7 on its outer wall to move accordingly, thereby achieving the effect of adjusting the tension of the conveyor belt 7 according to needs, ensuring the stability and efficiency of material transportation.
