[0029] Reference Figure 1 and Figure 2A cooling water tank 21 is fixedly connected above the lower fixed plate 1, a driving water pump 22 is fixedly connected to the side of the cooling water tank 21 above the lower fixed plate 1, a connecting hose 23 is fixedly connected to the water outlet of the driving water pump 22, a plurality of water outlet holes 24 are provided below the lower guide cylinder 4, the upper parts of the water outlet holes 24 provided below the lower guide cylinder 4 are all connected, the side of the cooling water tank 21 is connected to the water inlet end of the driving water pump 22 through a hose, one end of the connecting hose 23 is fixedly connected to the water outlet end of the driving water pump 22, and the connecting hose 23 is fixedly connected to the water outlet end of the driving water pump 22. The other end of the tube 23 is fixedly connected to the lower guide cylinder 4, and the connecting hose 23 is connected to the lower guide cylinder 4 to connect the water outlet holes 24 opened inside. The cooling water tank 21 stores cooling water, and the water pump 22 is driven to extract cooling water from the cooling water tank 21, and the cooling water is transported to the water outlet holes 24 below the lower guide cylinder 4 through the connecting hose 23 to be sprayed out, so as to preliminarily cool the sampling cylinder 10, the drilling bit 20 and the surrounding geological layers. The multiple groups of water outlet holes 24 opened below the lower guide cylinder 4 ensure that the cooling water can be sprayed out evenly, forming an effective cooling effect.

[0030] The working principle of the present invention is: before using the sampling device for mineral geological exploration with a cooling structure, first adjust the initial state, first place the entire device in the geological area to be explored, and adjust the movable end of the first electric telescopic rod 2 so that the foot pad 3 contacts and firmly supports the ground to ensure that the device is stable and does not shake. The second electric telescopic rod 5 is in the initial extension state, and the probe drill bit 20 is located inside the upper guide cylinder 8. Since the inner side of the lower opening of the sampling cylinder 10 is provided with an internal thread, and the upper side of the probe drill bit 20 is provided with an external thread adapted thereto, the sampling cylinder 10 can be rotated down to be tightly connected with the probe drill bit 20;

[0031] When sampling is required, the rotating motor 7 is started, and its rotating shaft drives the fixed extension column 9 to start rotating, driving the sampling tube 10 to start rotating. At the same time, the second electric telescopic rod 5 starts to shrink, and the drilling bit 20, driven by the sampling tube 10, starts to drill into the geological layer for sampling. During the sampling process, since the sampling tube 10 is provided with sampling holes 19 on the outside, the geological samples in the drilling process can enter the sampling tube 10 through these holes.

[0032] During the sampling process, the sampling tube 10 and the drilling bit 20 work continuously. The high temperature and long-term use may easily cause damage. At this time, the driving water pump 22 can be started to draw cooling water from the cooling water tank 21. The cooling water enters the driving water pump 22 through the hose and is then pumped to the connecting hose 23. The cooling water flows in the connecting hose 23 and is finally sprayed out through the multiple groups of water outlets 24 opened under the lower guide tube 4, thereby forming a preliminary cooling of the sampling tube 10, the drilling bit 20 and the geological layer below, which helps to reduce the high temperature effect during sampling and moistens the soil for better drilling.

[0033] After the sampling is completed, the motor 7 is stopped, and then the second electric telescopic rod 5 is driven to extend, driving the upper fixed extension column 9 and the sampling tube 10 thereunder to rise. When the sampling tube 10 rises to a certain height, the lifting paddle 15 is manually pulled to make the locking top block 14 disengage from the top block slot 18 of the locking protrusion 17, thereby releasing the connection between the sampling tube 10 and the fixed extension column 9. At this time, the sampling tube 10 can be removed, and the downward drilling bit 20 can be removed from under the sampling tube 10 by rotating it. At this time, the soil sample inside the sampling tube 10 can be easily taken out.

[0034] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
