A drilling machine power shaft 12 is provided at the output end of the small drilling machine 11. A drill rod 13 is threadedly connected to the lower end of the drilling machine power shaft 12. Several drill rods 13 are provided and are respectively connected to the lower end of the drilling machine power shaft 12 and clamped to an electric clamp. The inner wall of the claw 26 has a drill sampling head 14 threadedly connected to the lower end of the drill rod 13. The upper surface of the base plate 1 is fixedly connected to the first electric telescopic rod 15 below the slide rail 7.

One end of the telescopic rod of the first electric telescopic rod 15 is rotatably connected to the arc-shaped connecting rod 19. One end of the arc-shaped connecting rod 19 is rotatably connected to the upper surface of the clamping plate 17 via a shaft. There are two clamping plates 17 and two arc-shaped connecting rods 19, which are arranged symmetrically. The outer surface of the slide rail 7 is fixedly connected to the fixed arc-shaped slide rail 20. The inner wall of the fixed arc-shaped slide rail 20 is slidably connected to the... A sliding cylinder 21 is attached, and several sliding cylinders 21 are evenly distributed in a circular array. The outer surfaces of several adjacent sliding cylinders 21 are movably connected by connecting pieces 22. The upper surface of the clamping frame 23 is rotatably connected to symmetrically arranged rollers 24, and the outer surface of the rollers 24 abuts against the outer surface of the fixed arc-shaped slide rail 20. Several clamping frames 23 are evenly distributed in a circular array, and a second electric telescopic rod 25 is fixedly connected to the middle of the clamping frame 23. One end of the telescopic rod of the second electric telescopic rod 25 is fixedly connected to an electric gripper 26. The outer surface of the sliding cylinder 21 is fixedly connected to the clamping frame 23, and the inner side wall of the slide rail 7 is fixedly connected to the first... The third electric telescopic rod 27 has a telescopic rod with one end fixedly connected to a limiting connecting block 29, and a fixed arc-shaped slide rail 20 with one end rotatably connected to a movable arc-shaped slide rail 28. The inner side of the movable arc-shaped slide rail 28 is provided with an arc-shaped limiting groove 30. One end of the limiting connecting block 29 is slidably connected to the inner side wall of the arc-shaped limiting groove 30 through a limiting rod. The outer surface of the middle part of the slide rail 7 is fixedly connected to a second motor 32 through a support plate 31. The output end of the second motor 32 is fixedly connected to a drive turntable 33. The outer surface of the drive turntable 33 is provided with a groove that matches the sliding cylinder 21. Several grooves are provided and are evenly distributed in a ring array.

[0030] Specifically, the lower end of the first electric telescopic rod 15 is fixed to the base plate 1, and the upper end is rotatably connected to the clamping plate 17 via a limiting pivot 16. One end of the arc-shaped connecting rod 19 is hinged to the top of the telescopic rod of the first electric telescopic rod 15, and the other end is hinged to the upper surface of the clamping plate 17 via a shaft. When the first electric telescopic rod 15 retracts, the arc-shaped connecting rod 19 pushes the clamping plate 17 to rotate inward around the limiting pivot 16, so that the clamping grooves 18 of the two clamping plates 17 clamp the outer surface of the drill rod 13, thereby achieving... Drill rod 13 is fixed, fixed arc-shaped slide rail 20 is fixed to the outside of slide rail 7, movable arc-shaped slide rail 28 is connected to slide rail 7 via a third electric telescopic rod 27, sliding cylinder 21 is hinged end to end via connecting piece 22 to form a ring chain, nested inside fixed arc-shaped slide rail 20 and movable arc-shaped slide rail 28, clamping frame 23 is fixed to the outer surface of sliding cylinder 21, and its upper end roller 24 abuts against the outer surface of fixed arc-shaped slide rail 20 to ensure that clamping frame 23 maintains a vertical posture when moving. The second electric telescopic rod 25 is fixed in the middle of the clamping frame 23, and its telescopic rod end is connected to the electric gripper 26 for clamping the drill rod 13 to be replaced. The telescopic rod end of the third electric telescopic rod 27 is slidably connected to the arc-shaped limiting groove 30 of the movable arc-shaped slide rail 28 through the limiting connecting block 29, which can drive the movable arc-shaped slide rail 28 to rotate around the fixed arc-shaped slide rail 20 and adjust the path of the ring chain. The motor is fixed in the middle of the slide rail 7 through the bracket, and its output shaft is connected to the drive wheel. The groove on the outer surface of the drive wheel is adapted to the sliding cylinder 21. When the motor rotates, the drive wheel drives the sliding cylinder 21 to circulate within the fixed arc-shaped slide rail 20 and the movable arc-shaped slide rail 28, so that the clamping frame 23 carries the drill rod 13 to move below the drilling machine power shaft 12. Through the cooperation of the electric telescopic rod and the ring chain, the drill rod 13 to be replaced can be automatically transported to the designated position, and the threaded connection is completed by the rotation of the drilling machine power shaft 12. No manual operation is required, which improves the replacement efficiency and accuracy.

[0031] Please see Figure 1 , Figure 2 and Figure 6 A handrail 2 is fixedly connected to one side of the upper surface of the base plate 1. A traveling wheel 3 is rotatably connected to the outer surface of the base plate 1 outside the handrail 2. A threaded rod 4 is threadedly connected to the upper surface of the base plate 1. A support foot 5 is rotatably connected to the lower end of the threaded rod 4. A crank handle 6 is fixedly connected to the upper end of the threaded rod 4.

[0032] Specifically, the handrail 2 is vertically fixed to one side of the upper surface of the base plate 1. The traveling wheels 3 are installed on the outside of the base plate 1 via a rotating shaft, and the two traveling wheels 3 are distributed at an angle (the side closer to the handrail 2 is higher). When the operator holds the handrail 2 and lifts the right side of the device, only the two traveling wheels 3 touch the ground, and the device can be moved by pushing and pulling. The angled design allows the traveling wheels 3 to adapt to uneven terrain and reduce movement resistance. The threaded rod 4 is threaded to the upper surface of the base plate 1, and its lower end is connected to the support foot 5 via a rotating shaft. The upper end is fixed with a crank 6. After reaching the designated position, turning the crank 6 drives the threaded rod 4 to rotate, causing the support foot 5 to move up and down and adjust the level of the base plate 1. The two threaded rods 4 are located on both sides of the base plate 1 and can be adjusted independently to meet the needs of rapid leveling in complex terrain. The cooperation between the handrail 2 and the traveling wheels 3 enables the portable movement of the device, and the combination of the threaded rod 4 and the support foot 5 can quickly complete the leveling, reduce manual labor consumption, and improve the efficiency of field operations.

[0033] In summary, when using the overall equipment: The handrail 2 is pulled to an inclined position, at which point only the two wheels 3 are on the ground, facilitating movement and reducing operator workload. After moving to the designated position, the two threaded rods 4 are rotated via the crank 6 to adjust the extension height of the two support feet 5, thereby leveling the base plate 1. During drilling and sampling, the first motor 9 drives the lead screw 10 to rotate, thereby driving the slider 8 and the small drilling machine 11 to move up and down. The small drilling machine 11 drives the drill rod 13 to rotate while moving downwards, achieving the drilling effect. After the drill rod 13 has sunk completely, the telescopic rod of the first electric telescopic rod 15 retracts, allowing... Through the transmission action of the arc-shaped connecting rod 19, the two clamping plates 17 rotate inward along the corresponding limiting shaft 16. At this time, the two clamping slots 18 clamp the outer surface of the drill rod 13 respectively, fixing the drill rod 13. Subsequently, while the drilling machine power shaft 12 rotates in the opposite direction, the small drilling machine 11 rises, which disconnects the upper end of the drill rod 13 from the drilling machine power shaft 12. Then, the small drilling machine 11 rises to the top and drives the drive turntable 33 to rotate through the second motor 32. When the drive turntable 33 rotates, it drives the sliding cylinder 21 to slide inside the fixed arc-shaped slide rail 20. The sliding cylinder 21 and the connecting piece 22 form a chain in the fixed arc-shaped slide rail 20. The slide rail 20 and the movable arc-shaped slide rail 28 slide internally, thereby driving the corresponding clamping frame 23 to adjust its position. The multiple rollers 24 ensure that the angle of the clamping frame 23 does not shift. After the corresponding clamping frame 23 is adjusted to be below the drilling machine power shaft 12, the extension rod of the second electric telescopic rod 25 extends, driving the drill rod 13 held by the electric jaw 26 to move directly below the drilling machine power shaft 12. At this time, the lower end is also aligned with the upper end of the drill rod 13 fixed by the two clamping plates 17. Then, as the small drilling machine 11 descends, the drilling machine power shaft 12 rotates, connecting the lower end of the drilling machine power shaft 12 to the upper end of the new drill rod 13. The electric gripper 26 is released, the second electric telescopic rod 25 retracts, the second motor 32 drives the sliding cylinder 21 to move to the initial state, and the telescopic rods of the two third electric telescopic rods 27 extend, driving the two movable arc-shaped slide rails 28 to open outward to prevent the movable arc-shaped slide rails 28 from affecting the falling stroke of the small drilling machine 11. Then the small drilling machine 11 continues to fall until the lower end of the upper drill rod 13 is connected to the upper end of the lower drill rod 13. Then the first electric telescopic rod 15 controls the clamping plate 17 to release, and drilling can continue. The whole process is relatively intelligent and does not require manual intervention. Multiple drill rods 13 can be automatically connected one by one to the upper end of the drilling sampling head 14.

[0034] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
