AI Technical Summary
Existing grouting equipment used in mine tunnel construction requires waiting for the grout in the feed hopper to refill the pump tank after the grout is used up, which affects the grouting speed.
A grouting device for mine tunnel construction was designed. It uses a hollow disc that moves back and forth inside a pump tank and achieves uninterrupted grout supply through an opening and closing plate and a gear and rack mechanism. The motor drives the gear to rotate, which in turn drives the winding reel to rotate, thus achieving continuous grout delivery.
This ensures continuous material supply to the grouting equipment, increases the grouting speed, and avoids time delays caused by waiting for the grout to fill the pump tank.
