The invention relates to the technical field of slope construction, and discloses a drilling device for muck slope anchor rod protection. The drilling device comprises a mounting seat, wherein a driving motor is fixedly mounted on one side of the surface of the mounting seat, a driving gear is fixedly mounted on an output shaft of the driving motor, a driven gear which is located above the driving gear and is engaged with outer teeth of the driving gear is movably mounted on the mounting seat, a conveying auger is fixedly mounted on the surface of the driven gear, a material conveying column is fixedly mounted at the top end of the conveying auger, a positioning frame is fixedly connected to the side wall of the material conveying column, and the material conveying column is located in an inner cavity of the positioning frame. According to the drilling device, the material conveying column and the positioning frame are arranged at the top end of the conveying auger, so that in the working process, extrusion and fastening of the inner wall of a hole are achieved through the positioning frame, additionally, the top end of a drill bit cannot deviate, and finally, the purposes of preventing collapse of the formed hole and guaranteeing the drilling walking precision are achieved.
Description
technical field [0001] The invention relates to the technical field of slope construction, in particular to a drilling device for the protection of rock bolts on muck slopes. Background technique [0002] Slope anchor drilling is mainly used for drilling and reinforcing less stable slopes, and is widely used in roads, municipalities, foundation pits and other fields. [0003] During the working process of the existing slope bolt, it mainly fixes the drilling equipment to the forward pushing device (the forward pushing device such as the screw rotates to push the block forward), and the driving device is fixed on the pushing device. The motor has a feeding column and a drill bit fixedly installed on the drive shaft of the motor, so when the driving motor is constantly rotating and the pushing device is constantly pushing forward, the drilling device for the slope is carried out. [0004] But in the process of actual use, due to the continuous extension of the drill bit durin...
