Description

Technical Field

[0001] The utility model relates to the technical field of mine drilling machine equipment, in particular to a drilling machine. Background Art

[0002] A drill is a mechanical device designed to make holes in the ground or other materials. It mainly uses rotary cutting to penetrate materials of different hardness and types, such as rock, concrete, wood or metal. Drills are usually driven by electric, hydraulic or pneumatic drives, and specific models and designs can be used for different industrial and construction applications as needed.

[0003] For example, a Chinese utility model patent (CN219472035U) discloses a mining blasting drilling machine, which records: "Adjust the angle of the cylinder drive seat, pass the end of the limit rod through the positioning hole on the positioning plate, rotate the adjusting screw to embed the teeth into the tooth groove, and fix the positioning plate. The angle of the cylinder drive seat and the drill rod can be changed on the complex surface of the mine, which is convenient for adjusting the angle of the drill rod to facilitate multi-angle drilling and easy operation and use." It also records the technical problem that "the existing mining drilling machines are inconvenient to adjust the angle of the drill rod when operating on the complex surface of the mine."

[0004] To sum up the above, it can be known that in the prior art, a motor is used to drive a drill rod to drill holes in the ground. However, this method has the following technical problems: when a traditional drill rod is drilling holes in the ground, when the soil is relatively moist, more soil will adhere to the drill rod, and it is difficult to rely on the rotation of the drill rod to shake off the soil. It is necessary to stop drilling and use manual cleaning, which reduces the efficiency of construction. For this reason, the present application proposes a drilling machine to provide a new technical solution to solve the technical problems mentioned in the above patents. Utility Model Content
