For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0038] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0039] Reference Figure 1~Figure 5 , which is the first embodiment of the utility model, proposes a crawler 10-type omnidirectional pneumatic anchor drilling machine, including: an adjusting frame 2 is rotatably arranged on a frame 1; a drilling device 3 is arranged on the adjusting frame 2, the drilling device 3 is used to fix and drill drill rods, and the adjusting frame 2 is used to adjust the inclination angle of the drilling device 3; a protective shell 4 is arranged on the adjusting frame 2, and a protective space 410 is provided in the protective shell 4, and an opening 420 is provided at the bottom of the protective shell 4, the opening 420 is connected to the protective space 410, and the opening 420 is located above the drilling device 3, a feeding piece 5 is rotatably arranged in the protective space 410, and a plurality of notches 510 are provided on the feeding piece 5, and the notches 510 and the protective shell 4 form a storage space 520, and the storage space 520 is used to store drill rods. After the feeding piece 5 rotates, the drill rod leaves the storage space 520 through the opening 420 and enters the drilling device 3.

[0040] In this embodiment, the frame 1 is provided with a drilling device 3 and an adjustment frame 2, and the frame 1 mainly plays a supporting and adjusting role. The adjustment frame 2 can adjust the drilling direction of the drilling device 3, so as to adapt to a variety of different working conditions and improve the application range of the drilling rig. The protective shell 4 is arranged on the side of the frame 1 close to the drilling device 3, and the feeder 5 is located therein. The notch 510 in the feeder 5 is used to place the drill rod. When the drilling rig is about to work, the feeder 5 is rotated. At this time, the notch 510 of the drill rod on the feeder 5 will rotate to the opening 420 of the protective shell 4, ensuring that the drill rod can be smoothly clamped and drilled by the drilling device 3 without the need for manual positioning of the drill rod. Compared with manual placement of the drill rod, this method of placing the drill rod saves time and does not require manual alignment. Multiple drill rods can be stored in the feeder 5 at the same time, which further shortens the time and improves the work efficiency.

[0041] Furthermore, the feeding member 5 has a plurality of through holes 530, and also includes: a limiting member 6 is slidably arranged in the notch 510, and the limiting member 6 enters or leaves the notch 510 after sliding; a sliding rod 610 is slidably sealed and arranged in the through hole 530, and the sliding rod 610 slides along the through hole 530; two ends of the first elastic member 620 are respectively arranged on the limiting member 6 and the adjustment frame 2, and the first elastic member 620 is used to provide a force for the limiting member 6 to move in the direction of entering the notch 510.

[0042] In this embodiment, the stopper 6 serves to limit the position of the drill rod. Since the drill rod needs to leave the opening 420 on the protective shell 4, the size of the notch 510 is larger than the diameter of the drill rod. If the drill rod leaves the notch 510 only by gravity, the position of the drill rod will be inaccurate and dangerous. Therefore, the stopper 6 is designed to limit the position of the drill rod to ensure that the position of the drill rod when leaving the opening 420 is always the same, thereby improving the safety of the device. The sliding rod 610 is used to connect the stopper 6. When there is a drill rod on the stopper 6 and the opening 420 is connected to the notch 510, under the action of gravity, the stopper 6 and the drill rod will overcome the elastic force of the first elastic member 620 so that the drill rod leaves the opening 420 and is aligned with the drilling device 3. When the drilling device 3 separates the drill rod and the stopper 6, the gravity of the stopper 6 is not enough to completely overcome the elasticity of the first elastic member 620, and the stopper 6 will reset to complete the work of transporting the drill rod. The conveyance of the drill rod is completed by sliding of the elastic member and the limit member 6, which not only ensures the accuracy of the conveyance of the drill rod, but also improves the safety.

[0043] As a further technical solution, the limiting member 6 is an arc-shaped plate.

[0044] In this embodiment, the limit member 6 is an arc-shaped plate with a diameter comparable to that of the drill rod. Therefore, after the drill rod is fixed to the limit member 6, the drill rod can be accurately positioned, thereby improving the quality of transportation and ensuring the safety of the drilling operation.

[0045] As a further technical solution, it also includes: a ferromagnetic component 630 is arranged on the limiting component 6, and the ferromagnetic component 630 is used to assist in fixing the drill rod.

[0046] In this embodiment, the ferromagnetic part 630 is an electromagnet or a magnet that can assist the limit part 6 in fixing the drill rod. Through the fixation of the ferromagnetic part 630, even if the drilling rig itself shakes severely, the drill rod will not separate from the limit part 6. Only when the drilling device 3 works in the specified direction can the drill rod gradually overcome the magnetic force and leave the limit part 6, thereby improving the ability of the drilling rig to resist the external environment.

[0047] As a further technical solution, the feeding piece 5 has a receiving hole 710, and also includes: a control rod 720 is arranged on the adjustment frame 2, the control rod 720 is located in the receiving hole 710, the control rod 720 is a hollow structure, and the control rod 720 has a plurality of ventilation holes 730; after the feeding piece 5 rotates, the ventilation holes 730 are connected with the through hole 530 or the connection is cancelled.

[0048] In this embodiment, the control rod 720 is located at the center of the feeding member 5 and is fixed on the adjustment frame 2. The control rod 720 will only change the angle with the adjustment frame 2, but will not rotate with the feeding member 5. When the feeding member 5 rotates to the specified position, the through hole 530 at the corresponding position will be connected with the vent hole 730, and the compressed air in the vent hole 730 can make the sliding rod 610 slide in the through hole 530. Even if the angle of the adjustment frame 2 is too large and the gravity is insufficient to make the sliding rod 610 slide, the drill rod can be stably sent to the drilling device 3 by connecting the compressed air.

[0049] As a further technical solution, it also includes: the first telescopic member 8 is rotatably set on the frame 1, the first telescopic member 8 has a first telescopic end 810, the first telescopic end 810 is rotatably set on the adjustment frame 2, and the first telescopic member 8 is used to adjust the angle of the adjustment frame 2.

[0050] In this embodiment, the first telescopic member 8 is an oil cylinder, or an air cylinder. The oil cylinder is used because it can provide more powerful power than an air cylinder. Since the drilling rig usually works in mines and other areas, an air motor is used to provide kinetic energy for the oil cylinder to ensure the safety of underground operations. When the first telescopic member 8 moves, the angle of the adjustment frame 2 will change with the movement of the first telescopic member 8. By adjusting the first telescopic member 8, the angle of the adjustment frame 2 can be changed more stably, thereby improving safety and accuracy.

[0051] As a further technical solution, it also includes: a second telescopic member 9 is arranged on the adjustment frame 2 , the second telescopic member 9 has a second telescopic end, and the second telescopic member 9 is used to support the adjustment frame 2 .

[0052] In this embodiment, when the first telescopic member 8 is actuated, the angle of the adjustment frame 2 will change. Since the rotating frame and the protective shell 4 are heavy, the center of gravity may change easily when the rotating frame itself is tilted, causing the adjustment frame 2 to break. Therefore, a second telescopic member 9 is provided to support the rotating frame after tilting to prevent the rotating frame from being damaged due to its own weight, thereby ensuring the quality and efficiency of drilling.

[0053] As a further technical solution, it also includes: a track 10 is arranged on the frame 1, and the track 10 is used to drive the frame 1 to move.

[0054] In this embodiment, the drilling rig moves via the crawler tracks 10. Compared with common wheels, the crawler tracks 10 can adapt to more complex road conditions and will not affect the advancement of the drilling rig due to gravel on the road. At the same time, the crawler tracks 10 can also increase the grip area, reduce the impact of the drilling rig on the ground, and ensure the smooth operation of the drilling rig.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
