The invention relates to an anchoring device of an asteroid mining sampling machine. The anchoring device comprises a plurality of mechanical arms arranged on the periphery of the sampling machine and a multi-section type drill bit sleeve arranged at the ends of the mechanical arms; the multi-section type drill bit casing pipe comprises an expansion adjusting lead screw, a smooth root casing pipe, an expansion anchoring casing pipe and a drilling threaded casing pipe, the expansion adjusting lead screw is sequentially sleeved with the smooth root casing pipe, the expansion anchoring casing pipe and the drilling threaded casing pipe, and the bottom end of the expansion adjusting lead screw is in threaded connection with the inner wall of the drilling threaded casing pipe. Compared with the prior art, the expansion anchoring sleeve expands outwards to form the finger-shaped clamping jaw embedded into the soil of the asteroid, the double anchoring effect is achieved in combination with the drilling thread at the head of the drilling thread sleeve, and then it is guaranteed that the anchoring device is reliably fixed to the surface of the asteroid.

    本发明涉及一种小行星采矿采样机械的锚定装置,包括多个设于采样机械周围的机械臂,以及设于机械臂端部的多段式钻头套管;其中多段式钻头套管包括膨胀调节丝杆,以及依次套设于膨胀调节丝杆上的光滑根部套管、膨胀锚定套管、钻进螺纹套管,膨胀调节丝杆的底端与钻进螺纹套管内壁螺纹连接。与现有技术相比,本发明通过膨胀锚定套管向外膨胀扩张形成嵌入小行星土壤内部的手指状卡爪,结合钻进螺纹套管头部处的钻进螺纹,实现双重锚定效果,进而保证该锚定装置与小行星表面的可靠固定。
