[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0025] refer to Figure 1-3 and Figure 6 The core tube drilling equipment of this embodiment includes a frame 1. A protective frame 2 is fixedly connected to one side of the top of the frame 1. An electric cylinder 4 is horizontally fixedly connected to the side of the frame 1 away from the protective frame 2. A top block 6 is fixedly connected to the piston rod of the electric cylinder 4. A feeding chute 5 is horizontally fixedly connected to the top of the frame 1. A hopper 3 is provided on the side of the feeding chute 5 for storing tubes. A feeding mechanism 10 is provided between the feeding chute 5 and the discharge end of the hopper 3 for automatically feeding tubes. A mounting frame 7 is provided on the side of the feeding chute 5 away from the electric cylinder 4. A drilling mechanism 8 is provided on the top of the mounting frame 7 facing the feeding chute 5 for drilling tubes. A lower part is provided at the bottom of the side wall of the mounting frame 7 away from the feeding chute 5. The feeding mechanism 9 is used to automatically unload the pipe after drilling. The feeding mechanism 10 includes a feeding cylinder 1004. The piston rod of the feeding cylinder 1004 is fixedly connected to a movable block 1005. Several guide blocks 1007 are fixedly installed on the top of the movable block 1005. The top of the guide blocks 1007 is inclined downward in the direction towards the feeding chute 5. The feeding chute 5 is parallel to the electric cylinder 4 and is located directly below the top block 6. The inner side of the feeding chute 5 is V-shaped. The end of the top block 6 away from the electric cylinder 4 is a cone-shaped platform. The bottom of the top block 6 is fixedly connected to a feeding push plate 11. The cross-section of the feeding push plate 11 is V-shaped. The bottom of the feeding push plate 11 is slidably connected to the feeding chute 5. During drilling, the cylindrical tube is placed inside the hopper 3 along a direction parallel to the feeding chute 5. Under the action of gravity, the tube rolls towards the bottom of the hopper 3. The feeding mechanism 3 automatically feeds the tube at the bottom of the hopper 3, pushing the tube to the top inner side of the feeding push plate 11, so that the tube and the top block 6 are coaxially set. At this time, the electric cylinder 4 drives the top block 6 and the feeding push plate 11 to move along the feeding chute 5 towards the drilling mechanism 8, so that the tube moves accordingly. When the tube moves to the drilling station, the drilling mechanism 8 drills the tube. After the drilling is completed, the unloading mechanism 9 can realize the automatic unloading of the tube, thereby realizing the automatic feeding and unloading of the tube, effectively improving the automation level of tube feeding and unloading, and thus improving processing efficiency.

[0026] refer to Figure 4-5The hopper 3 is inclined upward along a direction perpendicular to the feeding chute 5. The feeding mechanism 10 also includes a lower slot 1001, which is located between the bottom of the hopper 3 and the feeding chute 5. A pair of connecting rods 1002 are vertically fixed to both sides of the bottom of the lower slot 1001. A base plate 1003 is horizontally fixed to the bottom of the pair of connecting rods 1002. The feeding cylinder 1004 is vertically fixed to the bottom of the base plate 1003. A guide plate 1008 is vertically fixed to the side wall of the lower slot 1001 facing the feeding chute 5. A pair of feeding guide rails 1006 are fixed to both sides of the side wall of the guide plate 1008 facing the hopper 3. The movable block 1005 is slidably connected between the pair of feeding guide rails 1006. During feeding, the feeding cylinder 1004 drives the movable block 1005 and the guide block 1007 to move upward along the feeding guide rail 1006. When the guide block 1007 moves upward, it pushes the pipe at the bottom of the hopper 3 upward until the pipe moves to the top of the guide plate 1008. At this time, the pipe rolls inside the feeding chute 5 under the action of the inclined guide block 1007 and falls into the inner side of the feeding push plate 11 at the top of the feeding chute 5, thus realizing automatic feeding of the pipe.

[0027] refer to Figure 7 The drilling mechanism 8 includes a drilling cylinder 801, which is vertically fixed to the top of the mounting frame 7. The piston rod of the drilling cylinder 801 is fixedly connected to a motor 802, the shaft of the motor 802 is fixedly connected to a drill bit 803, and a slider 804 is fixedly connected to the outside of the motor 802. A vertical slide rail 805 is fixedly connected to the inner side wall of the mounting frame 7, and the slider 804 is slidably connected to the vertical slide rail 805. A mounting base 806 is fixedly connected to the bottom of the mounting frame 7 on the side facing the feeding chute 5. A top column 807 is fixedly connected to the side wall of the mounting base 806 on the side facing the feeding chute 5. The top column 807 is coaxially arranged with the top block 6, and a through hole 808 is opened on the side wall of the top column 807. The through hole 808 is coaxially arranged with the drill bit 803. When drilling the pipe, the feeding push plate 11 moves the pipe to the outside of the top column 807. The diameter of the top column 807 matches the inner diameter of the pipe, thus supporting the pipe. The pipe is limited by the limiting groove 906 to improve the drilling accuracy. At this time, the drilling cylinder 801 drives the motor 802 and the drill bit 803 to move downward. When the motor 802 moves downward, it drives the drill bit 803 to start rotating until the bottom of the drill bit 803 contacts the pipe to drill a hole. During drilling, the feeding mechanism 10 resets, causing the top block 6 and the feeding push plate 11 to disengage from the pipe. After drilling is completed, the drill bit 803 resets and disengages from the pipe, realizing automatic drilling of the pipe.

[0028] The unloading mechanism 9 includes a fixed base 901, which is fixedly connected to the bottom of the mounting frame 7 on the side away from the feeding chute 5. A unloading cylinder 902 is horizontally fixedly connected to the side wall of the fixed base 901 away from the mounting base 806. A connecting block 903 is fixedly connected to the piston rod of the unloading cylinder 902. A pair of movable rods 904 are fixedly connected to the side wall of the connecting block 903 facing the mounting base 806. The movable rods 904 pass through the mounting base 806 and are slidably connected to it. The other end of the movable rod 904 is fixedly connected to a push block 905. A limiting groove 906 is opened on the side wall of the push block 905 facing the feeding chute 5. The limiting groove 906 is U-shaped. The bottom of the limiting groove 906 is coaxially arranged with the top column 807. The top column 807 passes through the push block 905 and is slidably connected to it. A discharge groove 12 is opened on the side of the feeding chute 5 facing the mounting base 806. A through groove 13 is opened on the top of the frame 1. The through groove 13 is located below the discharge groove 12. When discharging, the drill bit 803 disengages from the pipe. At this time, the discharge cylinder 902 drives the connecting block 903 and the movable rod 904 to move towards the mounting base 806, so that the push block 905 pushes the pipe sleeved on the outside of the top column 807 towards the feeding chute 5 until the pipe disengages from the top column 807 and then falls into the through groove 13 along the discharge groove 12, realizing the automatic discharge of the pipe.

[0029] Working principle: Before drilling, the cylindrical tube is placed inside the hopper 3 along a direction parallel to the feeding chute 5. Under the action of gravity, the tube rolls towards the bottom of the hopper 3. The feeding mechanism 3 automatically feeds the tube at the bottom of the hopper 3. During feeding, the feeding cylinder 1004 drives the movable block 1005 and the guide block 1007 to move upward along the feeding guide rail 1006. When the guide block 1007 moves upward, it pushes the tube at the bottom of the hopper 3 upward until the tube moves to the top of the guide plate 1008. At this time, the tube rolls into the inside of the feeding chute 5 under the action of the inclined guide block 1007 and falls into the inside of the feeding push plate 11 at the top of the feeding chute 5, realizing the automatic feeding of the tube. When the tube falls into the top inside of the feeding push plate 11, the tube and the top block 6 are coaxially set. At this time, the electric cylinder 4 drives the top block 6 and the feeding push plate 11 to move along the feeding chute 5 towards the drilling mechanism 8, so that the tube moves accordingly.

[0030] When drilling the pipe, the feeding push plate 11 moves the pipe to the outside of the top column 807. The diameter of the top column 807 matches the inner diameter of the pipe, thus supporting the pipe. The pipe is limited by the limiting groove 906 to improve the drilling accuracy. At this time, the drilling cylinder 801 drives the motor 802 and the drill bit 803 to move downward. When the motor 802 moves downward, it drives the drill bit 803 to start rotating until the bottom of the drill bit 803 contacts the pipe to drill a hole. During drilling, the feeding mechanism 10 resets, causing the top block 6 and the feeding push plate 11 to disengage from the pipe. After drilling is completed, the drill bit 803 resets and disengages from the pipe, realizing automatic drilling of the pipe.

[0031] During the unloading process, the drill bit 803 detaches from the pipe. At this time, the unloading cylinder 902 drives the connecting block 903 and the movable rod 904 to move towards the mounting base 806, causing the push block 905 to push the pipe sleeved on the outside of the top column 807 towards the upward unloading groove 5 until the pipe detaches from the top column 807. When the pipe groove 807 moves towards the downward unloading groove 12, it falls into the unloading groove 12 under the action of gravity, and then falls into the through groove 13 along the unloading groove 12, realizing the automatic unloading of the pipe.

[0032] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
