[0003] Currently, existing hydrogeological drilling equipment on the market has shortcomings in the coordination mechanism of impact and rotational drilling, making it difficult to achieve efficient synergy. When facing complex geological conditions such as hard rock, the equipment cannot fully utilize the advantages of the combined impact and rotation, resulting in low drilling efficiency and poor results. This not only prolongs the exploration cycle but also increases equipment wear and maintenance costs. Furthermore, the connection and buffer design of the drilling structure are inadequate, making it difficult to withstand the strong impact forces under complex geological conditions, posing significant safety hazards. Therefore, it is essential to develop a hydrogeological drilling equipment that optimizes the coordination of impact and rotational drilling and improves drilling efficiency in hard rock.

The power unit 1 is provided with a housing 11, and an impact sleeve 112 is provided on the housing 11. A sliding groove 114 is opened on the inner side of the impact sleeve 112. The transfer unit 2 includes a sleeve 21, a sliding rod 22, and a connector 23. The sliding rod 22 is connected to the top of the sleeve 21, and a fixing block 222 is connected to the outer side of the sliding rod 22. The fixing block 222 is snapped into the inner side of the sliding groove 114. The connector 23 is inserted into the inner side of the sleeve 21 for connecting the drilling structure. The sliding groove 114 is used to drive the sliding rod 22 to perform impact movement.

[0031] The buffer spring 212 installed on the inner side of the casing 21 abuts against the connector 23. During drilling operations, it can efficiently buffer the impact force from the drilling structure, effectively reducing the possibility of equipment damage due to impact. By setting the impact sleeve 112 and the slide bar 22, the impact operation and rotation operation are efficiently coordinated. When facing complex geological conditions such as hard rock, it can give full play to the advantages of the two operation methods, significantly improve the drilling effect and efficiency, and shorten the exploration cycle.

[0032] Furthermore, a support rod 111 is connected to the bottom of the casing 11, and the support rod 111 is connected to the outside of the impact sleeve 112. An insertion hole 113 corresponding to the slide rod 22 is opened on the inner side of the impact sleeve 112.

[0033] Furthermore, the groove 114 is formed inside the socket 113.

[0034] Specifically disclosed, a motor 12 is inserted into the casing 11, and the output end of the motor 12 is connected to a shaft 121, which is provided with a hexagonal prism.

[0035] Specifically disclosed, the sleeve 21 has slots 211 on both sides, and a buffer spring 212 is inserted into the inner side of the sleeve 21, which abuts against the connector 23.

[0036] It should be emphasized that the inner side of the slide rod 22 is provided with a sleeve hole 221 corresponding to the shaft 121.

[0037] Example 2

[0038] According to the appendix Figure 1-5As shown, a drilling device for hydrogeological survey includes a power unit 1 and a transfer unit 2. The transfer unit 2 is located below the power unit 1. The power unit 1 is provided with a housing 11, and an impact sleeve 112 is provided on the housing 11. A sliding groove 114 is opened on the inner side of the impact sleeve 112. The transfer unit 2 includes a sleeve 21, a sliding rod 22, and a connector 23. The sliding rod 22 is connected to the top of the sleeve 21, and a fixing block 222 is connected to the outer side of the sliding rod 22. The fixing block 222 is snapped into the inner side of the sliding groove 114. The connector 23 is inserted into the inner side of the sleeve 21 for connecting the drilling structure. The sliding groove 114 is used to drive the sliding rod 22 to perform impact movement.

[0040] Working Principle: When the equipment is in operation, the drill rod with the drill bit is first connected to the connector 23. Then, the equipment is used to drill a hole. During the drilling operation, the motor 12 drives the shaft 121 to rotate, which in turn drives the adapter unit 2 and the drilling structure to rotate synchronously. At the same time, the slide groove 114 drives the slide rod 22 to perform an impact motion. The two working methods work together to carry out the drilling operation. When encountering complex geological conditions and the drilling structure is subjected to a large impact force, the buffer spring 212 inside the sleeve 21 will quickly play a buffering role, effectively reducing the impact force on the equipment.
