[0003] Existing hydrogeological exploration drilling tools generate vibrations during operation, which makes the drilling tools prone to horizontal movement, resulting in rapid wear and reduced service life. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the tendency of drilling tools to move horizontally, which leads to rapid wear and reduced service life. This invention provides a hydrogeological exploration drilling tool.

[0012] As a further description of the above technical solution:

[0013] A limiting plate is fixedly connected to the upper surface of the mounting plate, and the upper surface of the limiting plate is provided with mating holes.

[0014] As a further description of the above technical solution:

[0015] The upper surface of the base plate has a connection hole, and a lifting plate is provided above the base plate.

[0024] This utility model has the following beneficial effects:

[0025] Compared with existing technologies, this hydrogeological exploration drilling tool features an extended first hydraulic rod that drives the insertion rod downwards, causing the rotating sleeve to slide against the insertion rod. The rotating sleeve restricts the direction of the insertion rod's movement, preventing excessive wear at the connection between the insertion rod and the first hydraulic rod. As the insertion rod moves downwards, it inserts the plug into the ground, further causing the baffle to contact the ground and limiting the length of the insertion rod's insertion into the ground. This reduces resistance when retracting the insertion rod, and the base plate is less prone to horizontal movement during drilling. After drilling is completed, the first hydraulic rod resets, causing the insertion rod to move upwards and the plug to leave the ground. Attached Figure Description

[0036] Example:

[0037] Reference Figure 1 - Figure 6 This utility model provides a hydrogeological exploration drilling tool, comprising a base plate 1, mounting plates 2 fixedly connected to the four corners of the upper surface of the base plate 1, a first hydraulic rod 3 fixedly connected to the surface of the mounting plate 2, a support mechanism provided at the four corners of the lower surface of the base plate 1, the support mechanism including a mounting frame 4, a rotating sleeve 5 fixedly connected to the upper surface of the mounting frame 4, a sliding ring 6 embedded in the upper surface of the base plate 1, the inner wall of the sliding ring 6 rotatably connected to the rotating sleeve 5, an insertion rod 7 fixedly connected to the output end of the first hydraulic rod 3, the inner wall of the rotating sleeve 5 slidably connected to the insertion rod 7, a plug 8 fixedly connected to one end of the insertion rod 7, both the plug 8 and the insertion rod 7 having an anti-rust layer, a baffle 9 fixedly connected to the bottom side of the insertion rod 7, a weight reduction hole 21 provided inside the insertion rod 7, and a moving wheel 2 rotatably connected to the inner wall of the mounting frame 4. 0. The base plate 1 moves on the ground via the moving wheels 20. The sliding ring 6 and the rotating sleeve 5 can rotate, facilitating the turning of the moving wheels 20. The surface of the moving wheels 20 is provided with a wear-resistant layer. After the base plate 1 is moved to the drilling position, the first hydraulic rod 3 extends, thereby driving the insertion rod 7 to move downward, which in turn causes the rotating sleeve 5 to slide with the insertion rod 7. The rotating sleeve 5 restricts the movement direction of the insertion rod 7, making it less likely for excessive wear to occur at the connection between the insertion rod 7 and the first hydraulic rod 3. The insertion rod 7 moves downward, inserting the plug 8 into the ground, further causing the baffle 9 to abut against the ground, limiting the length of the insertion rod 7 inserted into the ground, and reducing the resistance when retracting the insertion rod 7. During drilling, the base plate 1 is less likely to move horizontally. After drilling is completed, the first hydraulic rod 3 resets, thereby driving the insertion rod 7 to move upward, causing the plug 8 to leave the ground.

[0038] In this embodiment, refer to Figure 1 , Figure 2 and Figure 6 A limiting plate 10 is fixedly connected to the upper surface of the mounting plate 2. A mating hole 19 is provided on the upper surface of the limiting plate 10. A connecting hole 15 is provided on the upper surface of the base plate 1. The drill rod 13 passes through the connecting hole 15 and the mating hole 19. A lifting plate 11 is provided above the base plate 1. A second hydraulic rod 12 is fixedly connected to the surface of the lifting plate 11. The output end of the second hydraulic rod 12 is fixedly connected to the base plate 1. A guide rod 16 is fixedly connected to the upper surface of the base plate 1. The guide rods 16 are distributed in a rectangular array. A connecting ring 18 is embedded in the upper surface of the lifting plate 11. The inner wall of the connecting ring 18 is connected to the guide rod. The guide rod 16 is slidably connected to a fixed plate 17 at one end. A drilling motor 14 is fixedly connected to the upper surface of the lifting plate 11, and a drill rod 13 is rotatably connected to the lower surface of the lifting plate 11. The output end of the drilling motor 14 is fixedly connected to the drill rod 13. When drilling, the drilling motor 14 drives the drill rod 13 to rotate, and then the second hydraulic rod 12 retracts, thereby driving the lifting plate 11 to move down and drill through the drill rod 13. When the drill rod 13 moves up and down, the guide rod 16 slides with the connecting ring 18, which restricts the movement direction of the lifting plate 11 and makes it difficult for the drill rod 13 to deviate.

[0039] Working principle: Step 1, move the base plate 1 to the drilling location using the moving wheels 20;

[0040] Step 2: The first hydraulic rod 3 drives the insertion rod 7 to move downward, inserting the plug 8 into the ground, further making the baffle 9 abut against the ground, so that the base plate 1 is less likely to move horizontally during drilling.

[0041] Step 3: Drilling motor 14 drives drill rod 13 to rotate;

[0042] Step four: The second hydraulic rod 12 retracts, thereby driving the lifting plate 11 to move down, and drilling is carried out through the drill rod 13;

[0043] Step 5: After drilling is completed, the second hydraulic rod 12 extends, driving the lifting plate 11 to move upward and lifting the drill rod 13 off the ground.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
