Abstract

The invention discloses energy-saving automatic drilling equipment for mineral exploitation in the technical field of drilling equipment, which comprises a derrick, a drilling driving mechanism and a drilling mechanism are arranged on the derrick, the drilling mechanism comprises a vertical drill rod, a drill bit for crushing a soil layer is arranged at the bottom end of the drill rod, and the drilling driving mechanism is arranged on the derrick. A rod body of the drill rod is provided with a continuous spiral blade used for vertically conveying the crushed soil layer upwards along the rod body. The diameter of the lower blade of the continuous spiral blade is larger than that of the upper blade; a supporting cylinder is arranged in the circumferential direction of the continuous spiral blade, is hollow and is connected to the periphery of the drill rod in a sleeving manner; the inner wall diameter of the supporting cylinder is equal to the upper blade diameter of the continuous spiral blade, and the outer wall diameter of the supporting cylinder is equal to the lower blade diameter of the continuous spiral blade. The inner wall of a drilled hole site can be reinforced in the drilling process, and drilling equipment is prevented from being blocked due to hole collapse in the drilling process.

Description

technical field [0001] The invention belongs to the technical field of drilling equipment, and in particular relates to an energy-saving automatic drilling equipment for mining. Background technique [0002] In engineering drilling, some parts will be drilled for the purpose of directly obtaining boreholes or collecting structure samples. When drilling with existing drilling equipment, there are problems such as low drilling efficiency and poor chip removal. When the cuttings of the structure cannot be quickly removed, it is easy to cause blockage, which will affect the internal combustion efficiency of the prime mover and the energy transfer efficiency of the driving machine, making the drilling equipment low in efficiency and high in energy consumption. The research found that there are two main factors that cause the blockage during drilling: 1. The collapsed hole is formed after drilling, and the side walls of the drilled hole on both sides of the drill pipe collapse, an...
