[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a rock drill that reduces drill rod consumption in the opening machine, and has the following beneficial effects:

[0016] (1) In this utility model, the device is moved to a designated position and the rock drill body is opened to start rock drilling. The hydraulic telescopic rod drives the push block to move, which can adjust the height of the connecting frame and thus the height of the rock drill body. The electric slide and slider can adjust the horizontal position of the rock drill body, making it easier for the rock drill body to perform rock drilling in different positions. When the rock drill body vibrates during operation, it will move up and down. When the rock drill body moves, it will squeeze the damper and the second spring between the connecting frame and the slider. The damper and the second spring can absorb the vibration generated by the rock drill body during operation, thereby reducing the impact force generated by the rock drill body during operation and reducing the wear of the rock drill body. Furthermore, the use of the limiting block, limiting groove and the first spring can also absorb the vibration generated by the rock drill body during operation, thereby further reducing the impact force generated by the rock drill body during operation, which is convenient for protecting the drill rod on the rock drill body and helps to extend its service life.

[0027] Please refer to Figure 1-4A rock drill for reducing drill rod consumption in a rock drill includes a support plate 1. A connecting groove 3 is formed on one side surface of the support plate 1, and a through groove 5 extends through one side of the inner wall of the connecting groove 3 through the support plate 1. A hydraulic telescopic rod 2 is installed above the through groove 5 on one side surface of the support plate 1, and a push block 4 is fixedly connected to the output end of the hydraulic telescopic rod 2. One end of the push block 4 passes through the through groove 5 and the connecting groove 3. A connecting frame 6 is provided between the push blocks 4, and an electric slide table 7 is installed between the connecting frames 6. A slider 8 is installed on the electric slide table 7, and a frame 17 is provided on the bottom surface of the slider 8. Below the frame 17 is a... The device includes a rock drill body 9, with a connecting frame 23 on its top surface. The connecting frame 23 extends into the interior of a surrounding frame 17. A second spring 22 is provided between the connecting frame 23 and the slider 8. Dampers 21 are provided on both sides of the connecting frame 23 and the slider 8 away from the second spring 22. Limiting blocks 19 are provided on both sides of the connecting frame 23, with one end of each limiting block 19 extending into the interior of limiting grooves 20 opened on both sides of the inner wall of the surrounding frame 17. A first spring 18 is provided between the limiting block 19 and the limiting grooves 20. The device can be moved to a designated position, and the rock drill body 9 can be opened to allow operation. During rock drilling operations, the hydraulic telescopic rod 2 drives the push block 4 to move, which adjusts the height of the connecting frame 6, thereby adjusting the height of the rock drill body 9. The electric slide table 7 and slider 8 allow for horizontal adjustment of the rock drill body 9, facilitating drilling operations at different positions. When the rock drill body 9 vibrates during operation, it moves up and down. This movement compresses the damper 21 and the second spring 22 between the connecting frame 23 and the slider 8. By using the damper 21 and the second spring 22, the vibration generated by the rock drill body 9 during operation can be consumed and absorbed, thereby reducing the impact force generated by the rock drill body 9 during operation and reducing the wear of the rock drill body 9. Furthermore, by using the limit block 19, the limit groove 20 and the first spring 18, the vibration generated by the rock drill body 9 during operation can also be consumed and absorbed, thereby further reducing the impact force generated by the rock drill body 9 during operation, facilitating the protection of the drill rod on the rock drill body 9, and helping to extend its service life.

[0028] In one embodiment, grooves 10 are provided on both sides of the bottom surface of the support plate 1, and rollers 11 are installed in the grooves 10. By using the rollers 11 in the grooves 10 on the bottom surface of the support plate 1, the device can be moved to different positions for use, thereby improving the flexibility of the device.

[0029] In one embodiment, a connecting box 12 is provided on one side surface of the support plate 1, and electric telescopic rods 13 are installed on both sides of the lower top surface of the connecting box 12. A through-hole 14 is provided on the bottom surface of the connecting box 12. The output end of the electric telescopic rod 13 is fixedly connected to a limiting plate 15 through the through-hole 14. Teeth 16 are provided on both sides of the bottom surface of the limiting plate 15. When the device moves to a designated position, the electric telescopic rods 13 on both sides of the lower top surface of the connecting box 12 are opened. The electric telescopic rods 13 drive the limiting plate 15 to move. When the teeth 16 on the bottom surface of the limiting plate 15 extend into the ground, the device can be limited and fixed to prevent the device from tilting or shifting during operation, thereby facilitating the maintenance of the stability of the device during operation.

[0030] In one embodiment, the length and width of the limiting plate 15 are smaller than the length and width of the opening 14. Multiple teeth 16 are provided, and the multiple teeth 16 are evenly distributed in pairs on both sides of the bottom surface of the limiting plate 15, so that the limiting plate 15 can be moved into the connecting box 12 and thus the limiting plate 15 can be stored.

[0031] In one embodiment, the connecting frame 23 is matched with the surrounding frame 17 and is movably connected to the surrounding frame 17, allowing the connecting frame 23 to move within the surrounding frame 17. Furthermore, through the use of the first spring 18, the second spring 22, and the damper 21, the vibration generated by the rock drill body 9 during operation can be consumed and absorbed, reducing the impact force generated by the rock drill body 9 during operation. This facilitates the protection of the drill rod on the rock drill body 9 and helps to extend its service life.

[0032] In one embodiment, the push block 4, the through groove 5, and the connecting groove 3 are rectangular structures. The push block 4, the through groove 5, and the connecting groove 3 are slidably connected, which facilitates the movement of the push block 4, thereby allowing the height position of the rock drill body 9 to be adjusted.

[0033] In one embodiment, the limiting block 19 and the limiting groove 20 are rectangular structures. The limiting block 19 and the limiting groove 20 are slidably connected, allowing the limiting block 19 to move within the limiting groove 20. This allows the limiting block 19 to compress the first spring 18 and absorb its impact force, thereby further reducing the impact force generated by the rock drill body 9 during operation and facilitating the protection of the drill rod on the rock drill body 9.

[0034] In one embodiment, the control circuit of the control panel can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0035] Working principle:

[0036] In use, move the equipment to the designated position, open the rock drill body 9, and rock drilling can begin. The hydraulic telescopic rod 2 moves the push block 4, adjusting the height of the connecting frame 6, which in turn adjusts the height of the rock drill body 9. The electric slide table 7 and slider 8 allow for horizontal adjustment of the rock drill body 9, facilitating rock drilling from different positions. When the rock drill body 9 vibrates during operation, it moves up and down. This movement compresses the damper 21 and the second spring 22 between the connecting frame 23 and the slider 8. The damper 21 and the second spring 22 absorb and dissipate the vibrations generated during operation, reducing the impact and wear on the rock drill body 9. Secondly, the use of the limiting block 19, the limiting groove 20, and the first spring 18 can also absorb and dissipate the vibration generated by the rock drill body 9 during operation, thereby further reducing the impact force generated by the rock drill body 9 during operation, facilitating the protection of the drill rod on the rock drill body 9, and helping to extend its service life. The use of the rollers 11 in the groove 10 on the bottom surface of the support plate 1 allows the equipment to be moved to different positions, improving the flexibility of the equipment. When moved to the designated position, the electric telescopic rods 13 on both sides of the lower surface of the top of the connecting box 12 are opened. The electric telescopic rods 13 drive the limiting plate 15 to move. When the teeth 16 on the bottom surface of the limiting plate 15 extend into the ground, the equipment can be limited and fixed to prevent the equipment from tilting or shifting during operation, thereby facilitating the maintenance of the stability of the equipment during operation.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
