[0006] This application provides a grouting device for road and bridge construction, which adopts the following technical solution:

[0007] A grouting device for road and bridge construction includes a movable base, a mixing tank mounted on the movable base, a mixing mechanism mounted in the mixing tank, a discharge mechanism communicating with the mixing tank, a water spraying mechanism communicating with the mixing tank, and a cleaning mechanism mounted in the mixing tank.

Both the mixing rods and the installation plate abut against the side wall of the mixing tank.

[0008] By adopting the above technical solution, the rotating stirring rod agitates the slurry in the mixing tank, and the uniformly mixed slurry is injected through the discharge mechanism. After injection, the water spraying mechanism cleans the inner wall of the mixing tank, while the cleaning scraper scrapes off the slurry on the stirring rod and the side wall of the mixing tank, thereby improving the cleaning efficiency inside the mixing tank and reducing water consumption.

When the cleaning scraper comes into contact with the side wall of the mixing tank, the stirring rod drives the cleaning scraper to rotate, thereby cleaning the side wall of the mixing tank.

[0011] Preferably, the mounting plate has a limiting groove, and the sliding drive assembly includes a slider and a lead screw disposed in the limiting groove. One end of the lead screw is rotatably connected to the mounting plate, and the other end extends into the mounting tube and is rotatably connected to the mounting tube.

[0014] By adopting the above technical solution, the second motor drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, and the second bevel gear drives the lead screw to rotate, thereby realizing the movement of the cleaning scraper.

[0015] Preferably, the mounting plate is disposed at one end of the mounting tube near the top of the mixing tank, and the opening of the limiting groove faces the bottom of the mixing tank.

[0016] By adopting the above technical solution, the phenomenon of slurry entering the limiting groove and thus hindering the movement of the slider can be effectively reduced, thereby improving the smoothness and stability of the cleaning scraper movement process.

[0017] Preferably, the cleaning scraper has a scraping bevel on its side wall.

[0018] By adopting the above technical solution, the design of the scraping slope improves the cleaning efficiency of the cleaning scraper.

[0019] Preferably, the water spraying mechanism includes a water tank disposed on the movable base, a water pump whose inlet end is connected to the water tank, a water outlet pipe connected to the water outlet end of the water pump, a water spraying ring connected to the end of the water outlet pipe away from the water pump, and a plurality of water spraying pipes disposed on the water spraying ring, wherein the water spraying ring is disposed on the top of the mixing tank.

[0020] By adopting the above technical solution, the water pump delivers water from the water tank into the spray ring, and then the water enters the mixing tank through the spray pipe, thereby cleaning the inside of the mixing tank.

[0021] Preferably, the discharge mechanism includes a discharge funnel connected to the mixing tank and a valve disposed on the discharge funnel, and the installation pipe is inserted into the discharge funnel and is provided with spiral conveying blades.

[0022] By adopting the above technical solution, after the slurry is mixed, the valve is opened, and the installation pipe drives the spiral conveyor blades to rotate, thereby pushing the slurry through the discharge funnel for injection.

[0023] In summary, this application has the following beneficial technical effects:

[0024] 1. The water spray mechanism and the cleaning scraper work together to improve the cleaning efficiency inside the mixing tank and reduce water consumption;

[0025] 2.

When the cleaning scraper 62 moves to the end of the stirring rod 32 away from the installation pipe 31, the cleaning scraper 62 abuts against the side wall of the mixing tank 2. The first motor 331 drives the installation pipe 31 and the stirring rod 32 to rotate, thereby driving the cleaning scraper 62 to clean the side wall of the mixing tank 2, thus improving the cleaning efficiency of the mixing tank 2 and reducing water consumption.
