Description

Technical Field

[0001] This utility model relates to the field of gold mining technology, specifically to a pneumatic leg rock drilling device for ultra-thin vein-type gold ore bodies. Background Technology

[0002] A pneumatic rock drill is a mechanical device that uses compressed air as power for drilling into rocks. It uses compressed air to drive a piston to perform high-frequency reciprocating motion in a cylinder. When the piston is in its stroke, it impacts the drill bit at high speed, causing the drill bit to generate a strong impact force on the rock, breaking the rock and forming a dent.

[0003] A search revealed that patent number CN220101196U, entitled "Utility Model of a Pneumatic Leg Rock Drill," includes a rock drill, a handle, and a vibrating rod. Research and analysis revealed that while the vibrating rod can be encased in a sleeve and a base during use, allowing it to vibrate and extend within these components—providing support and buffering force—it also avoids the risk of breakage due to insufficient support at the center of the vibrating rod being too long. However, the following drawbacks also exist to some extent.

[0004] For example, without protective functions, rock debris, dust, and flying particles generated during rock drilling operations lack effective protection, which can easily pose a direct threat to the operator's eyes, face, and exposed skin. Furthermore, without adjustment functions, the handle angle cannot be flexibly adjusted according to the actual working scenario. In working surfaces of varying heights or in narrow spaces, the fixed-angle handle is difficult to adapt to the operational needs, which not only reduces operational flexibility but also affects drilling accuracy and efficiency due to insufficient force. To solve the above technical problems, we have designed an ultra-thin vein-type gold ore body pneumatic leg rock drilling device. Utility Model Content

[0005] The purpose of this invention is to provide an ultra-thin vein-type gold ore body pneumatic leg rock drilling device with the advantages of protective and adjustable functions. It solves the problems of existing pneumatic leg rock drills that cannot effectively block rock debris, dust and splashes generated during use, and cannot flexibly adjust the handle angle according to the actual working scenario.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic leg rock drilling device for ultra-thin vein-type gold ore bodies, comprising a body, with connecting blocks integrally formed on both sides of the front and rear sides of the body, a connecting rod movably connected through the right side of the right connecting block, an adjusting cylinder movably sleeved on the right side of the connecting rod via a bearing, a handle welded to the right side of the adjusting cylinder, a first positioning groove formed on the surface of the adjusting cylinder, positioning frames riveted to both the front and rear sides of the right side of the body, a pull rod movably connected through the opposite side of each positioning frame, a positioning plate riveted to the opposite end of each pull rod, a positioning rod riveted to the opposite side of each positioning plate, an adjusting frame riveted to the left side of the top of the body, an adjusting block movably connected to the inner cavity of the adjusting frame via a rotating shaft, a second positioning groove formed on the left side and top of the adjusting block, a baffle riveted to the right side of the adjusting block, a transparent plate inlaid on the top of the baffle, and a fastening bolt threaded through the left side of the adjusting frame.

[0007] Preferably, the opposite ends of the positioning rods all penetrate the positioning frame and extend into the inner cavity of the first positioning groove, and there are several first positioning grooves arranged around the surface of the adjusting cylinder.

[0008] Preferably, a spring is movably sleeved on the surface of the pull rod, and the opposite ends of the springs are in contact with the positioning plate.
