[0025] Reference Figure 1-6 , is an embodiment of the utility model, and provides a composite drill package with adjustable cutting spacing. The composite drill package with adjustable cutting spacing includes a suspension frame 1 and a mounting frame 2. The suspension frame 1 is connected to the machine body. The left and right sides of the mounting frame 2 are fixedly connected with support shafts 3. The ends of the two support shafts 3 that are away from each other are rotated to pass through the lower end of the suspension frame 1. The right side of the suspension frame 1 is fixedly connected with a motor A14. The right end of the support shaft 3 on the right side is fixedly connected to the output end of the motor A14. Each time the motor A14 is started, the support shaft 3 is driven to rotate half a circle.

[0026] The left and right inner walls of the installation frame 2 are slidably plugged with edge frames 23, and the edge frames 23 can only move up and down in the installation frame 2. Tension springs 4 are fixedly installed on the upper surfaces of the front and rear ends of the edge frames 23, and the upper ends of the tension springs 4 are fixedly connected to the inner walls of the installation frame 2. A movable frame 5 is arranged above the installation frame 2. The left and right inner walls of the installation frame 2 are both concave structures, and the tension springs 4 have a tendency for the edge frames 23 to drive the movable frame 5 away from the installation frame 2. The inner bottom walls of the concave structures on the left and right sides of the installation frame 2 are both toothed alveolar structures, and the bottom surfaces of the left and right ends of the movable frame 5 are both toothed structures. The toothed structure of the movable frame 5 is adapted to the toothed alveolar structure of the installation frame 2, and the toothed structure of the movable frame 5 is compatible with the toothed alveolar structure of the installation frame 2. When the tooth-shaped structure cooperates, the position of the movable frame 5 is fixed, the lower end of the movable frame 5 is slidably sleeved on the outer surfaces of the two ribs 23, the inside of the movable frame 5 is slidably inserted with a slider 6, and a pressing frame 7 is arranged above the movable frame 5. The left and right ends of the movable frame 5 are fixedly connected with vertical rods 22, and the upper ends of the vertical rods 22 slide through the bottom surface of the pressing frame 7 located above it. The vertical rods 22 ensure that the pressing frame 7 will not be misaligned front and back relative to the movable frame 5. The front and rear ends of the slider 6 are located below the pressing frame 7. When the pressing frame 7 is close to the installation frame 2, the slider 6 is pressed to fix the position of the movable frame 5, and at the same time, the movable frame 5 is pushed to cooperate with the tooth structure of the installation frame 2 to fix the position of the slider 6 and the movable frame 5.

[0027] Bending frames 8 are provided on both sides of the installation frame 2, and the left and right ends of the pressing frame 7 are respectively slidably sleeved on the outer surfaces of the two bending frames 8. The upper surface of the bending frame 8 on the left is rotatably connected with a longitudinal prism shaft 17, and a motor B15 is installed on the front of the bending frame 8 on the left. The front end of the longitudinal prism shaft 17 is fixedly connected to the output end of the motor B15. The upper surface of the movable frame 5 is rotatably connected with a transverse prism shaft 20, and the outer surface of the sleeve shaft 12 is fixedly sleeved with a worm wheel 16, and the rear of the worm wheel 16 is meshed with a worm 18, which is rotatably connected to the slider 6, and the worm 18 is slidably sleeved on the outer surface of the transverse prism shaft 20. The surface of the longitudinal prism shaft 17 is driven by the worm 18 to rotate synchronously when the transverse prism shaft 20 rotates. At the same time, the worm 18 can slide on the transverse prism shaft 20 when following the movement of the slider 6. The left end of the transverse prism shaft 20 is fixedly sleeved with a bevel gear A19, and the rear of the bevel gear A19 is meshed with a bevel gear B21. The bevel gear B21 is rotationally connected with the movable frame 5 located below. The bevel gear B21 is slidably sleeved on the outer surface of the longitudinal prism shaft 17. The longitudinal prism shaft 17 is located on the left side of the transverse prism shaft 20. The longitudinal prism shaft 17 drives the bevel gear B21 to rotate synchronously, and drives the bevel gear B21 to slide on the surface of the longitudinal prism shaft 17 when the movable frame 5 moves back and forth.

[0028] The bottom surface of the bent frame 8 is fixedly connected with an elastic telescopic rod 9, and the other end of the elastic telescopic rod 9 is fixedly connected to the mounting frame 2. The ends of the two bent frames 8 that are away from each other are fixedly connected with plug shafts 10. The two plug shafts 10 are located above the two supporting shafts 3. Ring plates 11 are fixedly installed on the inner walls on both sides of the lower end of the suspension frame 1. The elastic telescopic rod 9 has a tendency to push the plug shaft 10 to contact the inner ring surface of the ring plate 11. The two supporting shafts 3 are respectively located on the inner ring sides of the two ring plates 11. The two plug shafts 10 are in sliding contact with the inner ring surfaces of the two ring plates 11 respectively. The ring plate 11 is an elliptical structure, and the top of the inner ring surface of the ring plate 11 is in contact with the support shaft 3. The axial distance is the smallest, the bottom end of the inner ring surface of the ring plate 11 is at the largest axial distance from the support shaft 3, the two support shafts 3 are coaxially arranged, the two plug shafts 10 are coaxially arranged, the two ring plates 11 are coaxially arranged, and the plug shaft 10 is arranged parallel to the support shaft 3. When the plug shaft 10 moves to the highest point of the ring plate 11, the plug shaft 10 drives the pressure frame 7 to press the slider 6 and the movable frame 5 through the bending frame 8. When the plug shaft 10 moves to the lowest position of the ring plate 11, the elastic telescopic rod 9 pushes the pressure frame 7 away from the installation frame 2, so that the movable frame 5 and the slider 6 can move. The upper surface of the slider 6 is rotatably connected with a sleeve shaft 12, and the interior of the sleeve shaft 12 is detachably connected with a drill rod 13.

[0029] During use, when the drill rod 13 is working, the insertion shaft 10 is located at the top of the ring plate 11, pushing the bending frame 8 and the pressure frame 7 to press the movable frame 5 and the slide block 6, fixing the position of the drill rod 13, and the motor B15 drives the longitudinal prism shaft 17 to rotate, driving multiple bevel gears B21 to rotate, and the bevel gear A19 is engaged with the bevel gear B21, driving multiple transverse prism shafts 20 to rotate, and the worm 18 follows the rotation of the transverse prism shaft 20 and engages with the worm wheel 16 to drive the drill rod 13 installed in the sleeve shaft 12 to rotate. When the position between the drill rods 13 needs to be changed, the motor A14 is started to drive the support shaft 3 to rotate half a circle. The support shaft 3 drives the installation frame 2 and the insertion shaft 10 to rotate half a circle around the support shaft 3, and the elastic telescopic rod 9 pushes the bent frame 8 to drive the insertion shaft 10 to contact the bottom end of the ring plate 11, so that the elastic telescopic rod 9 drives the pressure frame 7 to gradually move away from the installation frame 2 through the bent frame 8, and the pressure frame 7 is released from the pressure on the movable frame 5 and the slider 6, so that the movable frame 5 and the slider 6 can move. When the slider 6 moves, the worm 18 slides on the transverse prism shaft 20. When the movable frame 5 moves, it drives the bevel gear B21 to slide on the longitudinal prism shaft 17, so that after the slider 6 moves, the longitudinal prism shaft 17 can continue to drive multiple drill rods 13 to rotate synchronously.

[0030] 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.
