Description

Technical Field

[0001] The utility model belongs to the technical field of road surface repair devices, and in particular relates to a road surface repair grouting device. Background Art

[0002] Pavement subsidence grouting construction is a foundation reinforcement technology that fills soil voids with solidifying materials to improve the bearing capacity and stability of the foundation. Grouting construction technology is widely used and can be used to solve problems such as foundation settlement and loose soil to ensure the safety and stable operation of infrastructure. The grouting materials are generally single-liquid cement slurry, cement-water glass slurry, water glass, etc.

[0003] A Chinese patent with application number CN202321882940.9 discloses a road repair grouting device, including a storage box, a motor box is provided on one side of the discharge plate, a first servo motor is fixedly installed inside the motor box, an output end of the first servo motor is splined to a first transmission rod, a first threaded rod is fixedly connected to the surface of the first transmission rod, and an auger rod is fixedly installed inside the first threaded rod.

[0004] The above technical solution drives the auger rod to move by connecting the first threaded rod to the first transmission rod, so that the auger rod starts to rotate, and the auger rod pushes the slurry entering the discharge plate forward, thereby realizing automatic slurry transportation and avoiding solidification. However, in actual use, the slurry it transports is viscous and can solidify. During the auger transportation process, mud will be adsorbed on the auger sheet. When it dries, the gap between the augers will gradually become smaller due to the solidification of the slurry, affecting the subsequent transportation effect.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0032] An elastic member is provided between the slotted plate 8 and the movable plate 9, and an elastic member is provided between the movable plate 9 and the second scraper 13;

[0033] A driving mechanism 14 that cooperates with the first scraper 10 and the second scraper 13 is installed on the upper side of the inner wall of the U-shaped frame 5 .

[0034] One aspect of the application of this embodiment is that when in use, by pouring raw materials into the feeding port 3, the raw materials will slide from the upper side of the U-shaped frame 5, flow to the upper side of the conveying mechanism 4 and flow downward, and be conveyed out through the conveying mechanism 4, reducing the possibility of blockage during use;

[0035] After use, the U-shaped frame 5 can be driven downward by rotating the driving mechanism 14, so that the slotted plate 8 moves with it, driving the gap between the first scraper 10 and the second scraper 13 and the blade of the conveying auger 402 to be clamped, and then the conveying auger 402 is rotated to first push the first scraper 10 to move. During the movement, the first scraper 10 is squeezed in the opposite direction through the elastic part inside the slotted plate 8 to scrape one side of the threaded blade 402, and the second scraper 13 contacts and scrapes the other side of the conveying auger 402 through the elastic part between the movable plate 9, thereby cleaning the conveying auger 402 after processing to avoid the slurry being adsorbed on the conveying auger 402 and drying, causing the gap between them to become smaller, affecting the conveying efficiency.
