This work process is called grouting.

A material injection port is opened at the left end of the top surface of the mixing tank. A mixing mechanism is installed in the mixing tank, and the conveying mechanism is fixedly connected to the bottom end surface of the mixing tank; when the mixing mechanism is running, the main shaft of the first motor drives the first bevel gear to rotate, and through the transmission of the second bevel gear and the third bevel gear, the second connecting rod and the first mixing rod rotate in opposite directions, so that the rotation direction of the second mixing rod is opposite to that of the first mixing rod.

[0052] Specifically, an annular convex plate 31 is fixedly connected to one end of the transmission shaft 11 away from the servo motor 10 . The annular convex plate 31 is in close contact with the bottom surface of the rocker plate 18 , and a peak-shaped protrusion is provided on the top surface of the annular convex plate 31 .

[0053] Specifically, an L-shaped support frame 32 is symmetrically fixedly connected to the top surface of the bearing plate 5 , a positioning rod 33 is rotatably connected to the middle of the top of the L-shaped support frame 32 , and an electric telescopic pump 34 is fixedly connected to the middle of the positioning rod 33 .

[0054] Specifically, the output end of the electric telescopic pump 34 is fixedly connected to the drilling motor 37, the surface of the positioning rod 33 is symmetrically fixedly connected to the arc guide frame 35, the middle of the arc guide frame 35 is provided with a guide groove 36, the surface of the drilling motor 37 is symmetrically fixedly connected to the sliding rod 38, the sliding rod 38 is slidably set on the inner wall of the guide groove 36, and the output end of the drilling motor 37 is transmission-connected to the drill rod 39.

[0056] Through the above structural design, when the device is used, the device is first moved as a whole to a suitable position. After completion, the positioning rod 33 of Zhai Dong causes the electric telescopic pump 34 to rotate in the middle of the L-shaped support frame 32. The position of the drill rod 39 can be adjusted while the electric telescopic pump 34 rotates. After the position adjustment of the drill rod 39 is completed, the drilling motor 37 is turned on, and the drilling motor 37 drives the drill rod 39 to rotate. The electric telescopic pump 34 is turned on to push the drilling motor 37 and the drill rod 39 to move to the positioning position for drilling. After the drill rod 39 is drilled to the appropriate position, the drilling motor 37 and the electric telescopic pump 34 are not turned off smoothly. At this time, the end of the drill rod 39 stays at the drilling position. After completion, the dry material is added to the inside of the mud mixing box 8 with a suitable amount of water.

At this time, the pressure chamber 25 sucks the mixed mortar inside the mud mixing box 8 into the interior through the first delivery pipe 24. The annular convex plate 31 continues to rotate and pushes the other end of the seesaw 18 to rise and generates a negative pressure inside the pressure chamber 25 by pulling the pressure rod 26 and the piston block 27. The mortar inside the mud mixing box 8 is sucked in, and at this time, the other end of the seesaw 18 drops to squeeze and transport the internal mortar into the second delivery pipe 29, and the mortar is transported to the third delivery pipe 43 through the second delivery pipe 29. The mortar enters the interior of the closed cover 42 through the third delivery pipe 43, and is grouted to the pre-drilled holes through the delivery groove 40 in the middle of the drill rod 39, thereby realizing automatic grouting of the cracks. After the crack grouting is completed, clean water is added to the mud mixing box 8, so that the pipelines inside the device can be cleaned.

[0057] Embodiment 2:

[0058] The grouting equipment and grouting method provided in Example 1 are further optimized. Specifically, Figure 4-Figure 5 As shown, a top supporting frame 13 is fixedly provided at the top of the mud mixing box 8, a screwing sleeve 14 is rotatably provided in the middle of the top supporting frame 13, a lifting threaded rod 15 is threadedly connected to the middle of the screwing sleeve 14, a connecting positioning block 16 is fixedly connected to the bottom end of the lifting threaded rod 15, a first rotating shaft 17 is fixedly connected to both sides of the connecting positioning block 16, a seesaw 18 is rotatably connected to the surface of the first rotating shaft 17, and a second shaft 19 is fixedly connected to both ends of the seesaw 18.

[0059] Through the above-mentioned structural design, the lifting threaded rod 15 can be driven to rise or fall by rotating the screw sleeve 14. The lifting threaded rod 15 can rise and drive the seesaw 18 to rise by connecting the positioning block 16. After the seesaw 18 rises, the piston block 27 can be driven to rise by the pressure rods 26 at both ends. In this way, the contact angle between the annular convex plate 31 and the seesaw 18 can be reduced, and the extrusion stroke of the piston block 27 can be effectively reduced, thereby reducing the mortar pouring speed. On the contrary, the descent of the seesaw 18 can increase the contact stroke between the annular convex plate 31 and the seesaw 18, thereby increasing the grouting speed.

The annular convex plate (31) rotates and drives the seesaw (18) to flip up and down with the first rotating shaft (17) as the axis. The pressure rod (26) drives the piston block (27) to move upward to form a negative pressure inside the pressure chamber (25). The mortar enters the pressure chamber (25) through the first delivery pipe (24). S4: turning on the electric telescopic pump (34) and the drilling motor (37), the drilling motor (37) cooperates with the drill rod (39) to drill a hole at the grouting position, and the electric telescopic pump (34) pushes the drill rod (39) to move and drill a hole at the grouting position; S5: The piston block (27) is pressed downward to transport the mortar in the pressure chamber (25) to the inside of the closed cover (42) through the second delivery pipe (29) and the third delivery pipe (43). The mortar enters the delivery groove (40) through the closed cover (42) and can be grouted to the drilling position.
