[0002] In tunnels on major transportation lines such as highways and railways, it is necessary to conduct exploration drilling surveys on unfavorable geological conditions such as caves and underground rivers. Advance drilling can quickly excavate tunnels and improve construction efficiency while ensuring the normal passage of major transportation lines. However, most of the equipment currently on the market for detecting unfavorable geological conditions can only use radar for detection before drilling, and judge the geology through the signal reflected by the radar. It is impossible to observe the geological details in front of the hole in real time during drilling, which can lead to inaccurate or even wrong judgments, causing casualties and affecting the construction progress.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0021] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The following is combined with Figure 1-4 The present invention is further described in detail:

[0023] Reference Figure 1 The present invention provides a poor geological body geophysical exploration device, comprising a carrier trolley 1, a drilling assembly 2 arranged on the carrier trolley 1, and a driver 11 for driving the drilling assembly 2 to move linearly;

[0024] Specifically, the carrier trolley 1 includes a crawler base and a platform disposed on the crawler base. The driver 11 is a hydraulic rod, a cylinder or a linear slide, and the driver 11 is fixedly connected to the platform through an L-shaped connecting plate, and the driving end of the driver 11 is connected to the driving assembly.

[0025] The drilling assembly 2 includes a driving motor 13 , a driving rod 21 and a stone crushing drill bit 22 .

[0026] Specifically, a mobile base 12 is provided on the platform, a rotating bracket 14 is provided on the mobile base 12, a driving rod 21 is rotatably provided on the rotating bracket 14, a driving motor 13 is connected to the mobile base 12 through a connecting plate, and a driving end of the driver 11 is connected to one end of the connecting plate.

[0027] Furthermore, in order to ensure the linear motion of the movable base 12, a slide groove may be provided on the platform, and the movable base 12 is arranged in the slide groove.

[0028] Reference Figure 2 and Figure 3 The driving rod 21 includes a bottom ring and a hollow rod, the bottom ring and the hollow rod are connected at intervals, an inner gear ring 24 is provided on the inner wall of the bottom ring, a first gear 27 and a second gear 28 meshing with each other are provided in the bottom ring, and the second gear 28 meshes with the inner gear ring 24, a stone crushing drill bit 22 is provided at the top of the hollow rod, a rotating shaft 26 is provided in the hollow rod, the rotating shaft 26 is sleeved on the first gear 27, and a rotating blade is spirally provided on the rotating shaft 26. The bottom ring and the hollow rod are connected by a plurality of first support frames 23.

[0029] Reference Figure 4The hollow rod is provided with a second support frame 25 symmetrically arranged front and back, and a bearing is arranged on the second support frame 25, and a rotating shaft 26 is rotatably connected to the center rod through the bearing. The second support frame 25 is composed of a plurality of ribs. The rotating blades are arranged on the rotating shaft 26 located between the second support frames 25. The top of the hollow rod is connected to the outside, that is, the middle of the stone crushing drill bit 22 is hollow and connected to the inside of the hollow rod.

[0030] When the output end of the driver 11 of the device is extended, the drilling assembly 2 can be moved forward. At the same time, when the output end of the driving motor 13 is rotated, the drilling assembly 2 can be operated. The output end of the driving motor 13 is fixedly connected to the first gear 27, and the second gear 28 is rotatably connected to the outer shell of the driving motor 13, so that when the output end of the driving motor 13 is rotated, the first gear 27 can be driven to rotate, and then the second gear 28 is driven to rotate by the mutual engagement between the first gear 27 and the second gear 28. The second gear 28 can also drive the inner gear ring 24 to rotate by mutual engagement with the inner gear ring 24;

[0031] Since the second gear 28 and the first gear 27 are externally meshed, and the second gear 28 and the inner gear ring 24 are internally meshed, the rotation directions of the first gear 27 and the inner gear ring 24 are different, and finally the rotation directions of the hollow rod and the rotating shaft 26 are different. Further, after the stone crushing drill bit 22 crushes the stone, the rotating shaft 26 can transfer the crushed stone to the side close to the drive motor 13, and then the crushed stone is discharged through the gaps between the multiple first support frames 23, and the operator does not need to clean the hole separately, which facilitates the operation of the device and improves work efficiency.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
