[0022] The screw rod 3 is driven to rotate by the setting of the first motor 2. When the screw rod 3 rotates, the slide plate 7 can move on the surface of the screw rod 3. When the slide plate 7 moves, the connecting block 4 on one side is synchronously opened along with one end of the slide plate 7, so that when the height of the grouting device is adjusted, the connecting block 4 can assist the up and down movement of the slide plate 7, so that the grouting device can perform joint action on cracks in dam bodies of different heights.

[0023] When the first gear 14 rotates, the first worm 16 at the bottom rotates synchronously. The rotation of the first worm 16 drives the first turbine 17 engaged on one side to rotate. The rotation of the first turbine 17 drives the second turbine 19 to rotate synchronously through the setting of the connecting rod 21. When the second turbine 19 rotates, the engaged second worm 18 also rotates synchronously, so that the auxiliary stirring rod 133 fixedly connected to the second worm 18 can move up and down with the inner rod 132 through the internal spring 134, so that when the mud is stirred, it can be stirred by the rotation and the synchronous action of up and down, so that the mud can be stirred more evenly and is convenient for use.

[0024] When the first gear 14 is driven to rotate by the second motor 12, the third worm 22 meshing on one side can be driven, so that the third worm 22 can drive the third gear 23. The third gear 23 rotates the fourth gear 24 fixedly connected to it to synchronously drive the fifth gear 25 to rotate, so that the fifth gear 25 rotates and the toothed disc 26 rotates synchronously. The rotation of the toothed disc 26 is arranged through the setting of the fixed rod 27 so that the meshing bevel gear 281 can rotate synchronously on the toothed disc 26. The rotation of the bevel gear 281 drives the scraper 29 to make a circular motion in the grouting tank 9, so that the second motor 12 drives the stirring device to stir the mud while also driving the scraper 29 to scrape the mud on the inner wall of the grouting tank, so as to avoid the mud sticking to the inner wall for a long time, which may easily lead to uneven mud stirring.

[0025] like Figure 1 As shown in , and 2, the connecting block 4 is composed of a first connecting rod 5, a second connecting rod 51, a third connecting rod 52, and a connecting rod 53. A universal wheel 6 is provided on the side of the base 1 away from the screw rod 3, and a slider 71 is fixedly connected to the side of the slide plate 7 close to the base 1. A corresponding slide groove is provided on the side of the base 1 close to the slider 71. A sleeve plate 72 is fixedly connected to the side of the slide plate 7 close to the screw rod 3, and the sleeve plate 72 is threadedly connected to the screw rod 3.

[0026] The above scheme is adopted: the connecting block 4 is composed of a first connecting rod 5, a second connecting rod 51, a third connecting rod 52, and a connecting rod 53, so that when the slide plate 7 is moved to adjust the height, the connecting block 4 can be synchronously driven to unfold through a series of structures, so as to assist the movement of the slide plate 7. The universal wheel 6 on one side of the base 1 can easily push the entire device to the vicinity of the position where grouting of the dam body cracks is required. The slide plate 7 is slidably connected to the slide groove of the base 1 through the slider 71, which ensures the stability of movement. The movement of the slide plate 7 drives the grouting tank 9 fixed thereon to adjust the height to meet the needs of grouting of dam body cracks at different heights. The sleeve plate 72 on one side of the slide plate 7 is threadedly connected to the screw rod 3. When the screw rod 3 rotates, the sleeve plate 72 moves up and down along the screw rod 3, thereby driving the slide plate 7 to move.

[0027] like Figure 1 , Figure 7 As shown, a stabilizing frame 8 is fixedly connected to one side of the grouting tank 9, a tank top sleeve 10 is provided on the side of the grouting tank 9 away from the slide plate 7, an outlet pipe 11 is provided on the side of the tank top sleeve 10 away from the grouting tank 9, a rotating plate 13 is fixedly connected to the output shaft end surface of the second motor 12, a main stirring rod 131 is fixedly connected to the side of the rotating plate 13 away from the second motor 12, an inner rod 132 is fixedly connected to the side of the rotating plate 13 away from the main stirring rod 131, and the inner rod 132 is fixedly connected to the auxiliary stirring rod 133 through a spring 134.

[0028] The above scheme is adopted: through the stabilizing frame 8 on one side of the grouting tank 9, the grouting tank 9 can be firmly fixed when adjusting the height and bottom, avoiding the instability of the grouting tank 9, and the fully stirred mud flows out from the outlet pipe 11 on the side of the tank top sleeve 10 at the top of the grouting tank 9 to grout the cracks in the dam body. The outlet pipe 11 is connected through a pipeline so that the pipeline is aligned with the cracks in the dam body, and the mud is injected into the cracks to complete the grouting treatment of the cracks in the dam body. The rotating plate 13 fixedly connected to the surface of the second motor 12 can drive the stirring rod to rotate, so as to stir the mud. The stirring rod is divided into a main stirring rod 131 and an auxiliary stirring rod 133, so that the stirring rod can rotate and move up and down, and the mud is fully stirred and fused at the same time. The stirring rod 133 is moved up and down by the setting of the spring 134 and the inner rod 132.

[0029] like Figure 3 As shown, the scraper 29 fits the inside of the grouting tank 9, the number of scrapers 29 is set to two, the second worm 18 is fixedly connected to the auxiliary stirring rod 133, the first worm 16 and the second worm 18 are located above the mud in the barrel, the interior of the tank top sleeve 10 is a cavity, the fixed rod 27 is rotatably connected to the tank top sleeve 10, and a barrel sleeve 30 is provided on one side of the second turbine 19, and the barrel sleeve 30 is fixedly connected to the rotating plate 13.

[0030] The above scheme is adopted: the design that the scraper 29 fits the inside of the grouting tank 9 can better scrape the mud. In the grouting tank 9, as the stirring process proceeds, the mud is easy to adhere to the tank wall. If the attached mud is not cleaned in time, on the one hand, it will affect the uniformity of stirring, and on the other hand, it may dry up during subsequent use, thereby affecting the normal operation of the entire grouting device. The scraper 29 fits tightly with the tank wall, and can continuously scrape the attached mud during the operation of the device, so that it returns to the mud body, which is convenient for the stirring work of the stirring rod. Moreover, the number of scrapers 29 is set to two. This design makes the scraping more complete. The two scrapers 29 can be used from different The tank wall is scraped off at different angles and positions, and they cooperate with each other to ensure that the mud on each part of the tank wall can be cleaned in time. The second worm 18 is fixedly connected to the auxiliary stirring rod 133. When the second worm 18 moves, it can directly drive the movement of the auxiliary stirring rod 133. This linkage design makes the stirring work more flexible and diverse. The movement of the auxiliary stirring rod 133 can stir the mud at different positions, breaking the limitations of the traditional stirring rod fixed position stirring. It can penetrate into different depths and areas of the mud to make the stirring more sufficient and uniform. The interior of the tank top sleeve 10 is a cavity. This design facilitates better operation of the overall setting, and the cavity structure provides space for installation and operation of various components of the device.

[0031] The working principle and use process of the present invention: First, the second motor 12 inside the grouting tank 9 is started, and the output shaft of the second motor 12 drives the first gear 14 to rotate. During this process, when the first gear 14 rotates, it drives the first worm 16 to rotate, and the first worm 16 is tightly meshed with the first turbine 17. This meshing relationship makes the first turbine 17 start to rotate under the drive of the first worm 16, and the rotation of the first turbine 17 further drives the swing rod 20 to move. The swing rod 20 swings along a specific trajectory, and its swinging force is transmitted to the connecting rod 21. The connecting rod 21 moves under the drive of the swing rod 20, thereby rotating the second turbine 19, and the second turbine 19 is meshed with the second worm 18. As the second turbine 19 rotates, the second worm 18 also rotates. Such a transmission mechanism enables the auxiliary stirring rod 133 fixedly connected to the second worm 18 to move up and down. The up and down movement of the auxiliary stirring rod 133 can stir the mud at different heights, thereby achieving a better stirring effect. This up and down stirring method can make the mud more evenly mixed, avoid the situation of inconsistent local mud concentration, and provide for subsequent grouting. The third worm gear 22 is engaged with the third gear 23. Under this meshing transmission, the third gear 23 starts to rotate and drives the fourth gear 24 to rotate. The fourth gear 24 is engaged with the fifth gear 25. Through this continuous meshing transmission, the fifth gear 25 is driven to rotate. The rotation of the fifth gear 25 drives the toothed disc 26 to rotate. The toothed disc 26 is an important transmission component. Its rotation drives the fixed rod 27 to rotate. The sleeve block 28 sleeved on the fixed rod 27 and the sleeve The bevel gear 281 and the scraper 29 on one side of the block 28 rotate accordingly, and the scraper 29 fits tightly against the inside of the grouting tank 9. During the rotation, the scraper 29 can effectively scrape off the mud attached to the inner wall of the tank. If the attached mud is not cleaned in time, it may dry up, thereby affecting the subsequent use and stirring effect. The continuous rotation of the scraper 29 can keep the inner wall of the grouting tank 9 clean, ensure that the mud can be fully mixed during the stirring process, improve the quality and stability of the mud, and provide reliable protection for the grouting work of the cracks in the lifting type dam body.
