[0031] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A support leg 2 is fixedly connected to the lower side of the slurry tank 1, and four support legs 2 are provided. The four support legs 2 are arranged in a circular array on the slurry tank 1. Through the setting of the support legs 2, the slurry tank 1 can be supported.

[0033] The specific implementation process of the utility model is as follows: when the underground mortar anchor rapid grouting device of the mine needs to be used, the motor 4 is started to drive the output shaft to rotate, so as to drive the stirring blade 5 to rotate, and the slurry inside the slurry tank 1 is stirred to accelerate the rapid discharge of the slurry, and when the output shaft of the motor 4 rotates, the installation box 6 can be driven to rotate, and then the threaded rod 9 is driven to rotate, and finally the scraper 11 is driven to rotate along the inner bottom of the slurry tank 1, and the slurry attached to the inner bottom of the slurry tank 1 is scraped and cleaned to avoid the problem of slurry waste;

[0034] The starting motor 2 7 drives the output end to rotate, so as to drive the threaded tube 8 to rotate. Under the relationship of the threaded connection, the threaded rod 9 can be driven to move, so that the threaded rod 9 drives the guide plate 10 to slide along the inner wall of the installation box 6, and guides the threaded rod 9, so that the threaded rod 9 can move downward stably, and then drive the scraper 11 to move downward, so that the scraper 11 contacts the inner bottom of the slurry tank 1, so as to avoid the problem that the scraper 11 is difficult to clean the inner bottom of the slurry tank 1 after the scraper 11 is worn. In this process, the inner wall of the clamping hole 12 squeezes the clamping ball 14, and the clamping ball 14 pushes the elastic rod 13 to deform, and finally causes the clamping ball 14 to break away from the clamping hole 12. Under the action of force, the clamping ball 14 slides along the output end surface of the motor 2 7. When the clamping ball 14 slides into the next clamping hole 12, the elastic rod 13 recovers its deformation to push the clamping ball 14 to clamp into the clamping hole 12, and the output end of the motor 2 7 is limited, and then the position of the scraper 11 is finely controlled to avoid the scraper 11 causing impact on the inner bottom of the slurry tank 1.

[0035] Starting motor three 19 drives the rotating end to drive gear 20 to rotate forward. Under the meshing relationship, gear 20 drives the semi-toothed ring 18 to rotate forward, and then drives the rotating shaft 16 to rotate, so as to drive the rotating ring 17 to rotate. Under the action of the rotating ring 17, the rotation stability of the rotating shaft 16 can be guaranteed, and finally the rotating shaft 16 drives the vibrating ball 21 to deflect, so that the vibrating ball 21 contacts the inner wall of the discharge pipe 15. Starting motor three 19 drives the rotating end to drive gear 20 to rotate in the opposite direction. Similarly, it can be obtained that gear 20 drives the semi-toothed ring 18 to rotate in the opposite direction, so that the vibrating ball 21 contacts the inner side of the discharge pipe 15. This cycle repeats itself, so that the rotating shaft 16 and the vibrating ball 21 can be continuously deflected back and forth, and the discharge pipe 15 can be oscillated to avoid the problem of slurry discharge blockage.
