Beneficial effects

[0009] 1. During the use of this adjustable subway tunnel grouting equipment, grouting is performed on the subway tunnel through the output pipe at the front of the equipment base. If the grouting angle needs to be adjusted, the worm gear motor at the bottom of the support platform drives the worm wheel at the bottom of the central shaft to rotate, which in turn drives the output pipe at the bottom of the ball shaft frame to adjust its position. In conjunction with the angle motor at the front of the ball shaft frame driving the central ball shaft to rotate, the central ball shaft drives the output pipe to adjust the grouting angle. During this process, the operator does not need to manually maintain the angle, reducing the burden on personnel and thus increasing the working efficiency of the equipment.

[0010] 2. During the use of this adjustable subway tunnel grouting equipment, the worm gear is driven to rotate by the worm motor at the bottom of the support platform, which in turn drives the worm wheel at the bottom of the central shaft to rotate. Because the transmission principle of the worm gear and worm wheel has a self-locking function, the adjusted angle is maintained, thereby enhancing the stability of the equipment.

[0011] 3. During the use of this adjustable subway tunnel grouting equipment, the mixing drum at the top of the equipment base stores the slurry, and the mixing motor at the rear of the mixing drum drives the mixing shaft to rotate. This causes the mixing shaft to rotate the scraper inside the mixing drum, thereby scraping up the slurry adhering to the inner wall of the mixing drum, preventing material accumulation and blockage, thus increasing the stability of the equipment.
