[0001] The invention relates to the technical field of mining, in particular to a high-efficiency rock breaking device for mining. Background Art

[0002] In the process of mining, large-scale mining drilling equipment is usually needed to crush the gravel, so as to take out the ore inside and achieve the effect of ore mining.

[0003] Common ore mining equipment usually uses a mechanical arm to drive the shell to move, and controls the drill bit in the inner wall of the shell to extend downward. The drill bit rotates and contacts the gravel, thereby achieving the effect of crushing and mining the stone. The shell is driven by the mechanical arm to move, so as to control the position of the shell and the drill bit, and the stone at different positions in the mine is crushed and mined.

[0004] However, considering that in the process of breaking rock with the drill bit, the outer wall of the drill bit contacts and collides with the outer wall of the rock, the drill bit may be damaged after long-term use. Therefore, the staff needs to stop the rock breaking device first, disassemble and remove the drill bit set in the inner wall of the shell, and install a new drill bit.

[0021] At the same time, the device is equipped with a lubrication mechanism. When the outer bearing moves downward, the bottom outer wall of the outer bearing will squeeze the top of the arc rod, and the extrusion force will drive the arc rod to move downward, so that the arc rod drives the push rod to move upward through the two-way telescopic rod, so that the sealing ball A is separated from the bottom of the metering cylinder during the upward movement of the push rod. At the same time, during the upward movement of the sealing ball A, the slider is driven to move outward along the guide rod through the connecting rod, and the sealing ball B set on the top is driven to move downward at the same time, so that the top of the metering cylinder is closed and the bottom is opened, so that the lubricating oil stored in the metering cylinder is transmitted to the inner wall of the outer bearing along the hose, further reducing the friction between the outer bearing and the inner bearing. At the same time, the quantitative design prevents the addition of too much lubricating oil, which leads to waste of materials.

[0022] The present invention provides a high-efficiency rock breaking device for mining, which has the following beneficial effects:

[0023] 1. The present invention realizes efficient drill bit replacement through a moving mechanism. When the drill bit needs to be replaced, the electric slide rail is started to drive the sliding plate and the moving plate to move, so that the used drill bit can be removed, and the spare drill bit can be moved under the motor. Then the hydraulic rod is used to connect the motor with the spare drill bit, and the drill bit is pushed out to continue the rock breaking work. At the same time, the staff can maintain and repair the damaged drill bit while the device is in continuous operation, which greatly improves the work efficiency, avoids the interruption of rock breaking caused by drill bit replacement, and ensures the continuity of rock breaking by the drill bit.

[0024] 2. The present invention is provided with a lubrication mechanism. When the outer bearing moves downward with the drill bit, it squeezes the arc rod, so that the top of the metering tube is closed and the bottom is opened, and the lubricating oil is transported to the inner wall of the outer bearing through the hose. This design can automatically and accurately add lubricating oil to the bearing, effectively reduce the friction between the outer bearing and the inner bearing, ensure the smooth rotation of the drill bit, and improve the service life and working performance of the drill bit.

[0025] 3. The present invention is provided with a control mechanism so that when the arc rod drives the sealing ball A to move upward, it automatically drives the sealing ball B to move downward, so that the bottom of the metering cylinder is opened and the top is closed at the same time, thereby preventing the addition of too much lubricating oil and causing a waste of materials.
