[0002] Drilling is a crucial foundational task in mining operations, preparing for subsequent blasting and extraction processes. Traditional mining drilling machines have several shortcomings. Firstly, their positioning and adjustment functions are relatively limited, making it difficult to flexibly adapt to different mine terrains and mining requirements. This results in inconsistent accuracy in drilling position and angle, impacting mining efficiency and quality. Secondly, the significant friction and vibration between the drill bit and the ore during drilling accelerates drill bit wear, reducing its lifespan and increasing mining costs. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides a mining drilling machine that solves the problem of inflexible positioning and adjustment in traditional mining drilling machines.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows:
[0005] A mining drilling machine includes a fixed mounting base and an outer frame. The bottom of the fixed mounting base has a movable component.

A linkage gear is mounted at one end of each adjusting screw. The two linkage gears are connected by a first internal gear adjusting belt. An adjusting motor is mounted at the other end of one of the adjusting screws. A limiting connector with an I-shaped cross-section is provided at the bottom of the outer frame. A limiting groove is formed below the adjusting screw in the fixed mounting base, corresponding to the shape of the limiting connector. After the bottom of the outer frame is fitted onto the adjusting screw, the limiting connector slides within the limiting groove. A first support column is provided at the top of the outer frame, and a drill bit body is mounted on the first support column via a transmission component.
[0006] Furthermore, the transmission assembly includes a drive motor, which is mounted on the outside of the first support column. The main shaft of the drive motor passes through the first support column and is connected to a first gear plate. The main shaft of the drive motor is rotatably connected to the first support column. A second gear plate is provided above the first gear plate and is rotatably mounted on the first support column.

[0007] Furthermore, a drill bit mounting seat and an adjusting bolt are provided between the drive shaft and the drill bit body. The adjusting bolt is a double-ended bolt, with one end connected to the drill bit body and the other end connected to the drill bit mounting seat after being fitted with a rubber ring. The drill bit mounting seat is connected to the drive shaft.
[0008] Furthermore, a second support column is provided at the top of the outer frame, and the drive shaft passes through the second support column and is connected to the drill bit mounting base.
[0009] Furthermore, the drill bit body has several damping rubber blocks on one side near the drill bit mounting seat. The drill bit mounting seat has mounting holes corresponding to the positions of the damping rubber blocks, and the damping rubber blocks are installed in the mounting holes.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] 1.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0021] A mining drilling machine includes a fixed mounting base 1 and an outer frame 7. The bottom of the fixed mounting base 1 is equipped with a moving component 23, which can be a tracked structure, facilitating the movement of the drilling machine within the mining site and enabling stable stopping during operation, while also adapting to varying production environments. Two symmetrical mounting slots are formed along the length of the top of the fixed mounting base 1. Adjusting screws 2 are rotatably mounted in each slot via bearings, ensuring smooth rotation of the adjusting screws 2. A linkage gear 5 is mounted at one end of each adjusting screw 2, and the two linkage gears 5 are tightly connected via a first internal gear adjusting belt 6, ensuring synchronous power transmission. An adjusting motor 18 is mounted at the other end of one of the adjusting screws 2. The adjusting motor 18 is connected to an external power supply and control system for easy operator control.
[0022] The bottom of the outer frame 7 is provided with a limiting connector 8. The limiting connector 8 has an I-shaped cross-section. A limiting groove 9 is precisely opened below the adjusting screw 2 inside the fixed mounting base 1, corresponding to the shape of the limiting connector 8. After the bottom of the outer frame 7 is fitted onto the adjusting screw 2, the limiting connector 8 can be slidably installed in the limiting groove 9. In this way, the outer frame 7 can move smoothly left and right under the drive of the adjusting screw 2.
[0023] The top of the outer frame 7 is provided with a first support column 20, and the drill bit body 14 is mounted on the first support column 20 via a transmission assembly. The transmission assembly includes a drive motor 19, which is securely mounted on the outside of the first support column 20. The main shaft of the drive motor 19 passes through the first support column 20 and is connected to a first gear plate 10 via a key. The main shaft of the drive motor 19 and the first support column 20 are rotatably connected via bearings. Above the first gear plate 10, a second gear plate 12 is rotatably mounted via bearings. The second gear plate 12 is connected to the drill bit body 14 via a transmission shaft 22. The first gear plate 10 and the second gear plate 12 are connected by a second internal tooth adjusting belt 11.
[0024] A drill bit mounting seat 13 and an adjusting bolt 15 are also provided between the drive shaft 22 and the drill bit body 14. The adjusting bolt 15 is a double-ended bolt. One end of the adjusting bolt 15 is tightly connected to the drill bit body 14 by a thread, and the other end is fitted with a rubber ring 16 and then connected to the drill bit mounting seat 13 by a thread. The drill bit mounting seat 13 is connected to the drive shaft 22 by a key connection.
[0025] The top of the outer frame 7 is also provided with a second support column 21. The drive shaft 22 passes through the second support column 21 and is connected to the drill bit mounting seat 13. The second support column 21 provides an additional support point for the drive shaft 22, making it more stable when rotating at high speed.
[0026] Several damping rubber blocks 17 are evenly distributed on one side of the drill bit body 14 near the drill bit mounting seat 13. The drill bit mounting seat 13 has mounting holes corresponding to the positions of the damping rubber blocks 17, and the damping rubber blocks 17 are tightly fitted and installed in the mounting holes.
[0027] When drilling operations are required for mining, the drilling machine is first moved to the designated working position using the moving assembly 23. Then, according to the actual drilling requirements, the operator starts the adjusting motor 18. The adjusting motor 18 drives one of the adjusting screws 2 to rotate. Under the action of the linkage gear 5 and the first internal gear adjusting belt 6, the other adjusting screw 2 rotates synchronously, thereby moving the outer frame 7 along the adjusting screw 2 to the appropriate position, determining the drilling position and angle. Next, the operator starts the drive motor 19, which drives the first gear disc 10 to rotate. The first gear disc 10 engages with the second gear disc 12 through the second internal gear adjusting belt 11, transmitting power to the transmission shaft 22. The transmission shaft 22 drives the drill bit body 14 to rotate at high speed. During drilling, the rubber ring 16 and the damping rubber block 17 effectively reduce drill bit vibration, protect the drill bit, and extend its service life. When the drill bit wears out and needs to be replaced, the operator only needs to unscrew the adjusting bolt 15 to easily replace the drill bit body 14.
[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
