Description

Technical Field

[0001] The invention relates to the technical field of down-the-hole drills, in particular to a down-the-hole drill ground driver. Background Art

[0002] A down-the-hole drill is a machine that, during the drilling process, sinks an impactor into the hole, uses the high-frequency impact of the impactor on the rock, and cooperates with the rotary mechanism to rotate the drill tool to achieve rock crushing and drilling operations. Compared with traditional rock drills, down-the-hole drills have higher drilling efficiency, especially in hard rock drilling. The down-the-hole drill ground anchor, also called an anchoring device, is a device installed on the down-the-hole drill to firmly fix the drill to the working ground. The ground anchor can effectively resist the reaction force and torque generated during the operation of the drill by tightly connecting the drill to the ground, preventing the drill from shifting and ensuring the accuracy of the drilling position.

[0003] In the prior art, when a down-the-hole drill is working, the drill is usually fixed to the ground by driving the supporting legs into the ground. However, the terrain of different construction areas is different. When the construction area is located on a slope or in a complex environment, the conventional ground driver cannot effectively fix the drill, which affects the drilling accuracy.

When the first forward and reverse motor is automatically turned off, the protruding part of the adjusting wheel rotates to the roller, so that the ground teeth are all moved outward, increasing the length of the ground teeth, so that the ground nails and ground teeth can penetrate into the more stable soil layer or rock layer of the slope, which greatly enhances the anchoring effect and stability of the drilling rig on the slope or in complex environments, and ensures that the drilling rig can work safely and stably on slopes of different slopes.

And drive the reset plate 311 to move toward the inner wall of the ground-piercing tube 301, so that the strong spring 312 is squeezed and contracted together. When the first forward and reverse motor 303 is automatically turned off, the protruding part of the adjusting wheel 305 rotates to the roller 310, so that the ground teeth 307 are all moved outward, increasing the length of the ground teeth 307, so that the ground nails 308 and the ground teeth 307 can penetrate into the more stable soil layer or rock layer of the slope, thereby greatly enhancing the anchoring effect and stability of the drilling rig on the slope or in complex environments. When there is no need to adjust the length of the ground teeth 307, start the first forward and reverse motor 303 again, driving the rotating rod 304 and the adjusting wheel 305 to rotate in the opposite direction. At the same time, the squeezed strong spring 312 drives the ground teeth 307 to move and reset by pushing the reset plate 311 to restore the initial state.
