[0002] Due to long-term vehicle traffic, roads are prone to subsidence areas. In such cases, it is necessary to repair the subsidence areas. During the repair process, the subsided roadbed is first treated, then repair materials are injected, the repair materials are compacted, and the roads are allowed to reopen after they have dried.

[0003] There are two main methods for injecting repair materials: one is to use a mixer truck for injection, and the other is to use manual filling. Regardless of the method, the injected material needs to be smoothed and compacted, which requires the use of a variety of different tools, which is time-consuming, labor-intensive, and very inefficient.

A groove is provided on the frame, within which a slider is slidably mounted. A linear drive assembly for moving the slider is also provided on the frame. The hydraulic cylinder A is located at the bottom of the frame and drives a scraper connected to it. A motor A is also provided on the frame to drive the rotation of both the hydraulic cylinder A and the scraper. The mounting frame is located at the bottom of the frame and features a liftable pressure roller. The scraper is positioned between the slider and the pressure roller. The bracket is mounted on the frame and includes a storage bin. A guide hopper is located at the bottom of the storage bin, and an inlet pipe communicating with its interior is located on the storage bin. A hollow tube communicating with its interior is located at the bottom of the guide hopper, and an outlet pipe communicating with its interior is located at the bottom of the hollow tube. The outlet pipe passes through the slider and is fixedly connected to it. Motor B is mounted on the top plate of the storage tank. Motor B drives a connecting shaft, on which a propeller blade is mounted. The propeller blade is located inside the storage tank and inserted into a hollow tube, with the outer edge of the propeller blade fitting against the inner wall of the hollow tube. A support rod is mounted on the shaft, and two agitators are symmetrically and rotatably mounted on the support rod. A gear is mounted at the top of the agitator shaft, and an internal gear ring is located inside the storage tank, with the gear located inside the internal gear ring and meshing with it.

[0006] Preferably, a camera is installed at the bottom of the frame, an operating panel is installed on the frame, a control switch is installed on the operating panel, and a display screen that is electrically connected to the camera in real time is installed on the operating panel.

[0007] Preferably, the linear drive assembly includes a drive motor, a lead screw, and a slide bar. The lead screw is located in a slide groove and is rotatably connected to the vehicle frame. The drive motor drives the lead screw. The slide bar is located in the slide groove and is parallel to the lead screw. Both the slide bar and the lead screw pass through a slider.

[0013] By setting a sliding slider and using a linear drive component to drive the slider to slide, the output position of the discharge pipe is changed, facilitating the uniform injection of repair material into the cracked and subsided foundation pit. A scraper is used to smooth the material in the pit, and then a pressure roller is used to compact it. A structure with a propeller and agitator inside the storage tank is incorporated. The agitator is connected to an internal gear ring via gears. When the propeller rotates, the agitator revolves around it while rotating at high speed, improving the mixing efficiency of the material in the storage tank and preventing sedimentation. Simultaneously, the propeller circulates and tumbles the raw material at the bottom, further enhancing mixing efficiency. When the material is pushed out in the reverse direction, the output speed and quantity can be controlled by adjusting the reverse rotation speed of the propeller. The entire device has high structural stability, is simple and convenient to operate, and is highly practical and suitable for widespread application. Attached Figure Description

[0018] Example 1

[0019] like Figure 1-3 As shown, this utility model proposes a roadbed subsidence repair device, including a frame 1, a hydraulic cylinder A5, a mounting frame 7, a bracket 11, a motor B17, and a support rod 20. A groove 101 is provided on the frame 1, within which a slider 3 is slidably mounted. A linear drive assembly 4 for driving the slider 3 is provided on the frame 1. The hydraulic cylinder A5 is located at the bottom of the frame 1 and drives a scraper 6. A motor A102 for driving the hydraulic cylinder A5 and the scraper 6 is provided on the frame 1. The mounting frame 7 is located at the bottom of the frame 1 and has a liftable pressure roller 9 mounted on it. The scraper 6 is located between the slider 3 and the pressure roller 9. A bracket 11 is mounted on the frame 1. A storage bin 12 is mounted on the bracket 11. A guide hopper 13 is mounted at the bottom of the storage bin 12. A feed pipe 14 communicating with the inside of the storage bin 12 is mounted on the storage bin 12. A hollow tube 15 communicating with the inside of the guide hopper 13 is mounted at the bottom of the hollow tube 15. A discharge pipe 16 communicating with the inside of the hollow tube 15 is mounted at the bottom of the hollow tube 15. The discharge pipe 16 passes through the slider 3 and is fixedly connected to it. A motor B17 is mounted on the top plate of the storage bin 12. The motor B17 drives a rotating shaft 18. A propeller blade 19 is mounted on the rotating shaft 18. The propeller blade 19 is located inside the storage bin 12 and inserted into the hollow tube 15, with the outer edge of the propeller blade 19 fitting with the inner wall of the hollow tube 15 with a clearance fit. The support rod 20 is mounted on the rotating shaft 18. Two agitators 21 are symmetrically and rotatably mounted on the support rod 20. A gear 22 is mounted at the top of the agitator shaft of the agitator 21. An internal gear ring 23 is mounted inside the storage tank 12. The gear 22 is located inside the internal gear ring 23 and meshes with it.

[0020] In this embodiment, the vehicle frame is first moved to the operating position. Then, the linear drive assembly 4 is activated to move the slider 3 and the opening of the discharge pipe 16 to the edge area of ​​the sinkhole. Next, the motor B17 is activated, driving the propeller blade 19 to rotate forward. The propeller blade 19 agitates the raw material in the storage hopper 12, preventing stratification caused by prolonged storage. When the rotating shaft 18 rotates, the support rod 20 rotates along with it, causing the agitator 21 to rotate as well. The agitator 21 then rotates around... While the rotating shaft 18 revolves, it also rotates at high speed under the meshing transmission of gears and internal gear rings, thus fully agitating the raw materials between the propeller blade 19 and the inner wall of the storage tank 12, achieving thorough agitation without dead angles and improving the efficiency of remixing the raw materials. Subsequently, the motor B17 drives the propeller blade 19 to rotate in the opposite direction, pushing the mixed raw materials into the hollow tube 15 and injecting them into the pit along the discharge pipe 16. Then, the linear drive assembly 4 is activated to appropriately lateralize the outlet of the discharge pipe 16, preventing the repair material in the pit from accumulating in the same location. Then, the motor A102 is activated to drive the scraper 6 to rotate, using the scraper 6 to level the material, and then the frame 1 is driven forward, using the pressure roller 9 to compact the material.

[0021] Example 2

[0022] like Figure 3 As shown, the roadbed subsidence repair device proposed in this utility model, compared with Embodiment 1, has cleaning plates at both ends of the support rod 20, and the cleaning plates on both sides are slidably connected to the inner wall of the storage bucket 12.

[0023] In this embodiment, the cleaning plate scrapes the inner wall of the mixing tank 12 when it rotates, preventing the raw materials in the storage tank 12 from adhering to its inner wall, so that the storage tank 12 remains clean after discharge. At the same time, the cooperative structure of the cleaning plate and the support rod 20 can improve the rotational stability of the agitator 21.
