AI Technical Summary
Traditional drilling equipment is prone to dust diffusion and mechanical devices that cannot adapt to drill cuttings blockage or changes in drill rod displacement when removing drill cuttings.
A drilling slag removal device was designed, including a spiral sleeve driven by a slag removal motor. The spiral sleeve rotates and removes drill cuttings through the spiral baffles. When stuck, the sleeve slips due to friction with the rotating wheel. It has a certain degree of flexibility to adapt to the movement of the drill rod. The device is combined with a slag collection bin and a rotating bin to collect drill cuttings.
It achieves dust prevention, avoids dust spread, improves the efficiency of drill cuttings removal, protects motor equipment, adapts to changes in drill rod movement, and enhances on-site visibility and efficiency in drilling operations.
