[0002] A drilling machine is a general term for machinery and equipment that uses a tool that is harder and sharper than the target object to create a cylindrical hole or cavity in the target through rotary cutting or rotary extrusion. In mining engineering, drilling operations are an indispensable part of mining, exploration, and other tasks.

[0003] Traditional mining drilling machines usually have fixed working angles and positions, which make it difficult to adapt to the complex and changing mining environment. Especially when the drilling direction and depth need to be frequently adjusted, traditional equipment is particularly inconvenient.

[0004] With the development of mining technology, the requirements for drilling equipment are becoming increasingly higher, especially in terms of positioning accuracy, operational flexibility, and equipment stability. Therefore, developing a mining drilling machine that can flexibly adjust the drilling direction and angle has become the key to improving mine work efficiency and safety. Utility Model Content

DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0020] Example: A mine drilling machine with adjustable position, such as Figure 1-Figure 3 As shown, it includes a base 10, and the base 10 is provided with a moving wheel 13 that facilitates its movement. The setting of the moving wheel 13 facilitates the transportation and repositioning of the entire device. A moving plate 9 is slidably installed on the top of the base 10, and an electric slide rail 11 is provided on the base 10. The electric slide rail 11 is arranged below the moving plate 9. The electric slide rail 11 is used to drive the moving plate 9 to move horizontally. The slider of the electric slide rail 11 is fixedly connected to the moving plate 9. By driving the electric slide rail 11, the horizontal movement of the moving plate 9 can be achieved, thereby adjusting the overall lateral position of the drilling machine. A first motor 8 is installed in the center of the moving plate 9, and a disc 1 is provided on the top of the moving plate 9. The output shaft of the first motor 8 is connected to the center of the disc 1. The first motor 8 is used to drive the disc 1 to rotate circumferentially Rotational motion, the first motor 8 is a servo motor, and the first motor 8 rotates according to the set angle, speed and direction, so as to realize the precise adjustment of the rotation angle and speed of the disc 1, thereby precisely adjusting the drilling angle of the drilling machine body 1. A U-shaped frame 2 is installed at the eccentric part of the top of the disc 1, and the lower part of the frame 4 is rotatably installed on the U-shaped frame 2. A hydraulic cylinder 3 and a drilling machine body 5 are installed on the frame 4. The piston rod of the hydraulic cylinder 3 is connected to the drilling machine body 5. The telescopic movement of the piston rod of the hydraulic cylinder 3 drives the drilling machine body 5 to move along the trajectory of the frame 4. The drilling machine body 5 is controlled to move up and down along the trajectory of the frame 4 through the telescopic movement of the piston rod of the hydraulic cylinder 3, thereby controlling the drilling operation of the drill rod of the drilling machine body 5 and realizing precise control of the drilling depth at the same time.

[0021] like Figure 2 As shown, a telescopic rod 7 is symmetrically mounted on the disc 1 for rotation, a connecting block 6 is slidingly provided on the back of the frame 4, and the movable end of the piston rod of the telescopic rod 7 is rotatably connected to the connecting block 6. The telescopic rod 7 drives the frame 4 to rotate around the rotational connection point with the U-shaped frame 2 through its telescopic movement to adjust the drilling angle of the drilling machine body 5. The drilling angle (i.e., the pitch angle) of the drilling machine body 5 is adjusted through the telescopic movement of the telescopic rod 7 to adapt to the requirements of different slopes or directions.

[0022] like Figure 3 As shown, a shock-absorbing block 12 is provided at the bottom of the base 10. The shock-absorbing block 12 is used to reduce the vibration generated during the operation of the machine and improve the working stability. At the same time, the setting of the shock-absorbing block 12 can also increase the friction coefficient between the base 10 and the placement plane, thereby improving the stability of the base 10.

[0023] like Figure 1 and Figure 4As shown, brackets 41 are symmetrically arranged on both sides of the lower part of the frame 4 with the drill rod of the drilling machine body 5 as the center, and a cleaning disk 14 is rotatably arranged between the brackets 41. The drill rod of the drilling machine body 5 passes through the cleaning disk 14. A second motor 15 is installed on the frame 4. A gear 16 is connected to the output shaft of the second motor 15. The gear 16 is engaged with the teeth on the annular outer wall of the cleaning disk 14. The rotating cleaning disk 14 is used to remove rock chips or other debris attached to the surface of the drill rod to ensure that the drilling operation proceeds smoothly. The cleaning disk 14 can pre-clean the drill rod of the drilling machine body 5 before drilling to improve the accuracy of drilling the drill rod. It can also remove rock chips or other debris attached to the surface of the drill rod after the drilling operation is completed to ensure the cleanliness of the drill rod, thereby extending the service life of the drill rod.

[0024] When in use, the device is conveniently moved to the drilling area by the moving wheel 13, and then the moving plate 9 is driven by the electric slide rail 11 to move horizontally along the base 10 to adjust the position of the disc 1 and the components on the disc 1, thereby adjusting the horizontal position of the drilling machine as a whole; then, the first motor 8 drives the disc 1 to rotate, and the U-shaped frame 2 rotates around the center of the disc 1, thereby driving the frame 4 connected to the U-shaped frame 2 and the drilling machine body 5 to rotate together, so as to adjust the drilling azimuth angle, and then the telescopic movement of the telescopic rod 7 drives the frame 4 to rotate around the rotation connection point with the U-shaped frame 2, thereby adjusting the drilling angle (i.e., pitch angle) of the drilling machine body 5 to adapt to The requirements of different slopes or directions are met; subsequently, the drilling machine body 5 is driven to move downward along the track of the frame 4 by the extension movement of the piston rod of the hydraulic cylinder 3, thereby controlling the drill rod of the drilling machine body 5 to perform drilling operations on the mine. At the same time, the depth of the drilling is controlled by controlling the extension distance of the piston rod of the hydraulic cylinder 3 to meet different drilling requirements; after the drilling is completed, the piston rod of the hydraulic cylinder 3 is retracted, thereby driving the drilling machine body 5 to move upward along the track of the frame 4, and the second motor 15 works and drives the cleaning disc 14 to rotate through the gear 16. The rotation movement of the cleaning disc 14 removes rock chips or other debris attached to the surface of the drill rod, thereby providing convenience for the next drilling operation.
