Description

Technical Field

[0001] This utility model relates to the field of geological exploration, specifically a core drilling rig with a quick-assembly and disassembly drill bit. Background Technology

[0002] Core drilling rigs are core equipment for geological exploration and mineral sampling. Their drill bits need to be changed frequently to adapt to different rock strata, such as soft soil, hard rock, and fractured zones. The drill bits are usually fixed by threads, which makes it inconvenient to replace and disassemble them. Direction adjustment is often fixed by universal wheel brakes, which can easily cause shaking during operation and lead to angle deviation.

[0003] Existing core drilling rigs with quick-release drill bits generally use threaded fixing, which is inconvenient when changing and disassembling them. Sometimes, the threads can get completely jammed when they are covered by impurities. Direction adjustment often uses a single fixing method with universal wheels and brake pads, which is prone to shaking and deviation during operation, resulting in angular deviation and delays in work. Therefore, there is an urgent need for a core drilling rig that can both quickly release and install drill bits and prevent angular deviation. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a core drilling machine with quick assembly and disassembly of drill bits, so as to solve the problems of traditional threaded connections being difficult to disassemble and unstable fixing after directional adjustment when using existing core drilling machines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a base frame, with casters installed at the lower end of the base frame. Bolt holes are provided at both ends of the base frame, with adjusting bolts installed at the inner ends of the bolt holes. A fixing pad is installed at the lower end of the adjusting bolts. A handle is installed at the upper end of the base frame, and a motor bracket is installed at the upper end of the base frame. A drilling rig through hole is provided at the center of the motor bracket. A drive motor is installed at the upper end of the drilling rig through hole. A coupling is installed at the lower end of the drive motor. A drilling rig shaft is installed at the lower end of the coupling. A first engaging groove is provided at the bottom end of the drilling rig shaft. A second engaging groove is provided at the right end of the first engaging groove. A spring groove is provided at the lower end of the second engaging groove. A spring clip is installed at the inner end of the spring groove. A buckle is installed at the outer end of the spring clip. A drilling rig drill bit is installed at the upper end of the buckle.

[0006] Preferably, the base frame is threadedly connected to the adjusting bolt, and the adjusting bolt is arranged parallel to the base frame.

[0007] Preferably, the coupling is movably connected to the drill shaft, and the drill shaft forms a rotating structure with the motor bracket through the drill through hole.

[0008] Preferably, the first engagement groove is a square structure, and the first engagement groove is arranged in a circular array with respect to the central axis of the drilling rig shaft.

[0009] Preferably, the spring slot engages with the spring strip, and the spring strip forms a telescopic structure with the first engaging slot via a buckle.

[0010] Preferably, the second engaging groove is engaged with the buckle, and the spring strip is tightly fitted with the buckle.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model, through the design of the drill shaft, first engagement groove, second engagement groove, spring groove, spring strip, buckle, and drill bit, allows for quick replacement without tools by engaging the engagement structure and spring strip, avoiding the pain point of thread jamming and inability to disassemble, and significantly improving work efficiency.

[0013] This utility model uses a base frame, casters, bolt holes, adjusting bolts, and fixing rubber pads. After the casters' brake pads are initially fixed, the adjusting bolts are tightened, and the fixing rubber pads at the bottom of the bolts press against the ground, achieving multi-point rigid fixation and preventing angular displacement.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] Please see Figures 1-5 A core drilling rig for quick assembly and disassembly of drill bits includes a base frame 1. A caster wheel 2 is mounted on the lower end of the base frame 1. Bolt holes 3 are provided at both ends of the base frame 1. Adjusting bolts 4 are installed inside the bolt holes 3, and fixing rubber pads 5 are installed at the lower ends of the adjusting bolts 4. A handle 6 is mounted on the upper end of the base frame 1. A motor bracket 7 is mounted on the upper end of the base frame 1. A drilling rig through hole 8 is provided in the center of the motor bracket 7. A drive motor 9 is mounted on the upper end of the drilling rig through hole 8. A coupling 10 is mounted on the lower end of the drive motor 9. A drilling rig shaft 11 is mounted on the lower end of the coupling 10. A first engaging groove 12 is provided at the bottom end of the drilling rig shaft 11. A second engaging groove 13 is provided on the right end of the first engaging groove 12. A spring groove 14 is provided at the lower end of the second engaging groove 13. A spring strip 15 is installed inside the spring groove 14, and a buckle 16 is installed on the outer end of the spring strip 15. The upper end is equipped with a drill bit 17. The base frame 1 is threadedly connected to the adjusting bolt 4, and the adjusting bolt 4 is set parallel to the base frame 1. The coupling 10 is movably connected to the drill shaft 11, and the drill shaft 11 forms a rotating structure with the motor bracket 7 through the drill through hole 8. The first engagement groove 12 is set with a square structure, and the first engagement groove 12 is arranged in a circular array around the central axis of the drill shaft 11. The spring groove 14 is engaged with the spring strip 15, and the spring strip 15 forms a telescopic structure with the first engagement groove 12 through the buckle 16. The second engagement groove 13 is engaged with the buckle 16, and the spring strip 15 and the buckle 16 fit tightly. Through the engagement structure and the cooperation of the spring strip 15, the pain point of thread jamming is avoided, and quick replacement can be completed without tools. The fixing rubber pad 5 at the bottom of the adjusting bolt 4 is pressed against the ground to achieve multi-point rigid fixation and prevent angular displacement.

[0023] Working principle: During use, adjust the angle of handle 6. After confirming the angle, press down the brake pad on the universal wheel 2 to complete the initial fixation. Then, rotate the adjusting bolts 4 on both sides of the base frame 1 clockwise until the fixing rubber pads 5 at the bottom of the adjusting bolts 4 are pressed against the ground to complete multi-point fixation. Align the buckle 16 at the lower end of the drill bit 17 with the first engagement groove 12 and insert it vertically. The buckle 16 and the snap ring 15 will be squeezed together. Since the contact surface between the snap ring 15 and the buckle 16 has rounded corners, the buckle 16 can continue to be inserted along the rounded corners, and the snap ring 15 is squeezed. Compress and rotate the drill bit 17 clockwise to slide the buckle 16 into the second engagement groove 13. Since the depth of the second engagement groove 13 is higher than that of the first engagement groove 12, the snap ring 15 loses pressure, resets and pushes out, locking the buckle 16. After the drilling work is completed, rotate the drill bit 17 counterclockwise, and the buckle 16 slides out from the second engagement groove 13 to the first engagement groove 12. Lift the drill bit 17 to complete the disassembly. This completes the use of the device.
