Abstract

This utility model discloses a grouting device for the reuse of abandoned boreholes in coal mines, belonging to the field of abandoned borehole grouting. It includes a grouting mechanism, a mixing component, and a moving component. The grouting mechanism includes a servo motor, with a reducer installed at the front end of the servo motor. A conveying pipe is detachably installed at the front end of the reducer, and a spiral conveying roller is installed inside the conveying pipe. The spiral conveying roller is connected to the reducer. A grouting pipe is detachably installed at the end of the spiral conveying roller away from the reducer. Several grouting holes are equidistantly opened on the side surface of the grouting pipe. This utility model, through the combination of the grouting mechanism, mixing component, and moving component, not only facilitates the mixing of mortar before grouting, avoiding blockages and improving grouting smoothness and practicality, but also facilitates the movement of the grouting device to perform grouting operations at different locations in the abandoned borehole, thus improving the ease of use of the grouting device.
