DETAILED DESCRIPTION

[0023] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0024] Example

[0025] like Figure 1-Figure 5As shown, a drilling device for geological exploration proposed in one embodiment of the utility model includes a lifting assembly and a mounting seat 6, wherein the bottom plate 1 is used as the foundation of the entire device and is firmly fixed on the ground. The top plate 2 is located above the bottom plate 1, and the two are vertically and parallelly fixedly connected by four sturdy guide rods 3 to form a stable support frame. The guide rods 3 not only play a supporting role, but also serve as a guide track when the mounting seat 6 is lifted; between the bottom plate 1 and the top plate 2, a threaded rod 4 is rotatably connected through a bearing. The lower end of the threaded rod 4 is fixed to the bottom plate 1 through a bearing to ensure that it can only rotate but not move up and down. A servo motor 5 is fixedly installed on the upper end of the top plate 2, and the output end of the servo motor 5 is fixedly connected to the upper end of the threaded rod 4 through a coupling or other appropriate connector, so that the servo motor 5 can drive the threaded rod 4 to rotate; the mounting seat 6 is a component with an internal thread, and its internal design has a thread matching the threaded rod 4, so it can be threadedly sleeved on the periphery of the threaded rod 4. At the same time, the outside of the mounting seat 6 is also designed with four guide holes corresponding to the guide rod 3, so that the mounting seat 6 can be slidably sleeved on the outer periphery of the guide rod 3. When the servo motor 5 drives the threaded rod 4 to rotate, the mounting seat 6 will move up and down along the axis of the threaded rod 4 and the guide rod 3; one end of the mounting seat 6 is rotatably connected to a shaft rotating rod 7 through a bearing, and the other end of the shaft rotating rod 7 is rotatably connected to one end of the rotating arm 8 through an appropriate connecting piece such as a pin shaft, a universal joint, etc. In this way, the rotating arm 8 can rotate around the axis of the shaft rotating rod 7.

[0026] Among them, a rotary core seat 9 is fixedly installed at the end of the rotating arm 8, and a rotating head 10 is firmly fixedly connected to the lower end of the mandrel of the rotary core seat 9. The rotating head 10 is the main part of the drilling component, which is used to install and drive the rotary hole rod 11 for drilling operations; the interior of the rotating head 10 is designed with a mounting structure that matches the rotary hole rod 11, and the two are connected by a quick disassembly mechanism such as a buckle, a locking ring, etc. This design allows the rotary hole rod 11 to be replaced or repaired conveniently and quickly, thereby improving the operating efficiency; in order to drive the rotating head 10 and the rotary hole rod 11 to perform rotational movement, a driving structure is also connected between the rotating arm 8 and the rotary core seat 9. The driving structure is driven by a motor or other power source installed on the rotating arm 8 or the rotary core seat 9, and the power is transmitted to the rotating head 10 through a transmission device, thereby driving the rotary hole rod 11 to perform rotary drilling.

[0027] Furthermore, the quick disassembly and assembly mechanism is mainly composed of a limit socket 12, an n-type block 14, a strip groove 15, a fixed rod 16, a spring 17, a movable sleeve block 18, a limit plug rod 19 and a lap plate 20. A limit socket 12 is provided at the periphery of the end of the rotary hole rod 11 for cooperating with the limit plug rod 19 to achieve fixation. The periphery of the rotating head 10 is fixedly connected with the n-type block 14, and a strip groove 15 is provided on both sides of the n-type block 14. A fixed rod 16 is arranged in parallel in the groove. A spring 17 is sleeved on the fixed rod 16, and the two ends of the spring 17 are respectively fixedly connected to the end wall of the strip groove 15 and one end surface of the movable sleeve block 18 slidably sleeved on the fixed rod 16. The movable sleeve block 18 can slide freely in the strip groove 15. A through hole 13 is designed at the top of the n-type block 14 for the limit plug rod 19 to pass through. The periphery of the limit plug rod 19 is fixedly connected with a lap plate 20, and the two sides of the lap plate 20 are respectively fixedly connected to the sides of the two movable sleeve blocks 18. When the hole-turning rod 11 needs to be installed, the limit plug hole 12 of the hole-turning rod 11 is aligned with the through hole 13 on the rotating head 10 and pushed in with force. At this time, the lap plate 20 drives the movable sleeve block 18 to slide to both ends in the strip through groove 15 and compress the spring 17. When the limit plug hole 12 completely enters the range of the through hole 13, the elastic force of the spring 17 resets the movable sleeve block 18, and then pushes the limit plug rod 19 through the through hole 13 and inserts it into the limit plug hole 12, so as to realize the rapid installation of the hole-turning rod 11. When disassembling, just press the lap plate 20 lightly to make the limit plug rod 19 withdraw from the limit plug hole 12, and the hole-turning rod 11 can be removed from the rotating head 10.

[0028] Furthermore, the driving structure includes a servo motor 21, a belt pulley 22, a belt pulley 23 and a linkage belt 24. The servo motor 21 is fixedly mounted on the lower end surface of the rotating arm 8, and the output end thereof is fixedly connected to the belt pulley 22. The upper end of the mandrel of the rotating core seat 9 is fixedly connected to the belt pulley 23. The outer peripheries of the belt pulley 22 and the belt pulley 23 are tightly wound through the linkage belt 24 to form a transmission connection. When the servo motor 21 is started, the belt pulley 23 and the rotating core seat 9 and the rotating head 10 connected thereto are driven to rotate through the transmission action of the belt pulley 22 and the linkage belt 24, thereby driving the rotary hole rod 11 to perform drilling operations.

[0029] Furthermore, the angle adjustment component includes a servo motor 3 25, a belt pulley 3 26, a belt pulley 4 27 and a linkage belt 2 28. The servo motor 3 25 is fixedly mounted on one end of the mounting seat 6, and the output end thereof is fixedly connected to the belt pulley 3 26. The periphery of the shaft rotating rod 7 is fixedly connected to the belt pulley 4 27. The peripheries of the belt pulley 3 26 and the belt pulley 4 27 are tightly wound through the linkage belt 2 28 to form a transmission connection. When the servo motor 3 25 is started, the belt pulley 4 27 and the shaft rotating rod 7 connected thereto are driven to rotate through the transmission action of the belt pulley 3 26 and the linkage belt 2 28, thereby driving the rotating arm 8 to rotate around the axis of the shaft rotating rod 7 to achieve the angle adjustment of the drilling direction.
