[0016] A method for using a sampling probe for prospecting engineering comprises the following steps:

[0017] S1. First, the mounting head is fixedly connected to the external driving device. Then, according to the actual sampling requirements, the adjustable transmission component is driven to move by the adjusting component to adjust the transmission ratio between the driving roller and the conical roller. Then, the external driving device is controlled to drive the sampling tube to move into the sampling hole.

[0018] S2. The operator controls the driving device to drive the roller on the sampling tube to move down close to the inner wall of the sampling hole, and the device performs intermittent multi-stage sampling. After the sampling is completed, the driving device drives the sampling tube to move out of the sampling hole, and then takes the material storage box out of the sampling box to obtain the sample;

[0019] S3. If sampling is required again after obtaining the sample, install the material storage box into the bottom of the sampling box. The operator drives the adjustable transmission component to move through the adjustment component, thereby adjusting the transmission ratio of the driving roller and the conical roller, and repeats the above sampling steps to achieve multi-stage sampling operations at different levels.

[0020] The present invention has the following advantages: when in use, the operator adjusts the position of the movable sleeve according to the sampling needs, the movable sleeve drives the driving frame to move downward through the adjusting column, and the driving frame drives the transmission belt to move. During the movement of the transmission belt, the diameter of the conical roller at one end will change, and the transmission ratio of the driving roller and the conical roller will change. In this case, the sampling interval of the device can be adjusted. After the sampling interval is adjusted, the operator installs the mounting head on the external driving device, and then moves the roller on the side wall of the sampling tube downward along the inner wall of the sampling hole. When the roller moves, it drives the transmission bevel gear to rotate through the driving bevel gear, and the transmission bevel gear The driving roller is driven to rotate through the transmission column, and the driving roller drives the conical roller to rotate through the transmission belt, and the mounting plate at the bottom of the conical roller rotates. When the induction block at the bottom of the mounting plate contacts the valve stem, the valve stem will move down, and the ventilation groove on the valve stem will move into the air transmission pipe. Under the action of the air supply pump, the gas passes through the ventilation valve and finally enters the pneumatic cylinder. The pressure in the pneumatic cylinder increases, which will drive the piston column at one end of the piston block to move horizontally. The piston column drives the mounting rod to move horizontally through the driving plate. When the mounting rod drives the sampling box to move out of the sampling port, the transmission gear and the gear rod slide relative to each other, and the transmission gear will not rotate. The sampling box is inserted into the inner wall of the sampling hole to realize sampling;

[0021] When the sensing block is separated from the valve stem, the valve stem will be reset under the action of the reset member, and the gas filling in the pneumatic cylinder will be lost. Under the action of the telescopic member, the mounting rod drives the sampling box above to reset to realize sampling. During the resetting movement, the transmission gear contacts the gear rod to realize one-way transmission. The transmission gear drives the sampling box above the rotating column to rotate to realize the replacement of the sampling box. As the sampling cylinder continuously moves downward, the above sampling steps are repeated to realize multi-stage continuous interval sampling. No manual external control is required during the sampling process, and the operation is more convenient and the sampling efficiency is higher. It is suitable for sampling environments with harsh environments and poor signals, and is more practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Example 3, please refer to Figure 1-Figure 7 , a method for using a sampling probe for prospecting engineering, comprising the following steps:

[0042] S1. First, the mounting head 6 is fixedly connected to the external driving device. Then, according to the actual sampling requirements, the adjustable transmission component is driven to move by the adjusting component to adjust the transmission ratio between the driving roller 39 and the tapered roller 16. Then, the external driving device is controlled to drive the sampling tube 1 to move into the sampling hole.

[0043] S2, the operator controls the driving device to drive the roller 4 on the sampling tube 1 to move down close to the inner wall of the sampling hole, and the device performs intermittent multi-stage sampling. After the sampling is completed, the driving device drives the sampling tube 1 to move out of the sampling hole, and then takes the storage box 37 out of the sampling box 36 to obtain the sample;

[0044] S3. If sampling is required again after obtaining the sample, the material storage box 37 is installed into the bottom of the sampling box 36. The operator drives the adjustable transmission component to move through the adjustment component, thereby adjusting the transmission ratio of the driving roller 39 and the conical roller 16, and repeats the above sampling steps to achieve multi-stage sampling operations at different levels.

[0045] Example 4, please refer to Figure 1-Figure 7 The actual application scenario of this device is used for sampling in the sampling hole in the prospecting project. The actual use principle is that the operator adjusts the position of the movable sleeve 9 according to the sampling needs. The movable sleeve 9 drives the driving frame 23 to move downward through the adjusting column 7, and the driving frame 23 drives the transmission belt 38 to move. During the movement of the transmission belt 38, the diameter of the conical roller 16 at one end will change, and the transmission ratio of the driving roller 39 and the conical roller 16 will change. In this case, the sampling interval of the device can be adjusted. After the sampling interval is adjusted, the operator installs the mounting head 6 on the external driving device, and then moves the roller 4 on the side wall of the sampling tube 1 downward along the inner wall of the sampling hole. When the roller 4 moves, it drives the transmission bevel gear 41 to rotate through the driving bevel gear 42, and the transmission bevel gear 41 drives the transmission bevel gear 41 to rotate through the transmission The column 40 drives the driving roller 39 to rotate, and the driving roller 39 drives the conical roller 16 to rotate through the transmission belt 38, and the mounting plate 15 at the bottom of the conical roller 16 rotates. When the induction block 24 at the bottom of the mounting plate 15 contacts the valve rod 28, the valve rod 28 will move down, and the venting groove 25 on the valve rod 28 will move into the air transmission pipe 13. Under the action of the air supply pump 12, the gas passes through the venting valve 27 and finally enters the pneumatic cylinder 17. The pressure in the pneumatic cylinder 17 increases, which will drive the piston column 19 at one end of the piston block 21 to move horizontally. The piston column 19 drives the mounting rod 18 to move horizontally through the driving plate 14. When the mounting rod 18 drives the sampling box 36 to move out of the sampling port 3, the transmission gear 29 and the gear rod 34 slide relative to each other, and the transmission gear 29 will not rotate. The sampling box 36 is inserted into the inner wall of the sampling hole to realize sampling;

[0046] When the sensing block 24 is separated from the valve stem 28, the valve stem 28 will be reset under the action of the reset member 26, and the gas filling in the pneumatic cylinder 17 will be lost. Under the action of the telescopic member 20, the mounting rod 18 drives the sampling box 36 above to reset and realize sampling. During the resetting movement, the transmission gear 29 contacts the gear rod 34 to realize one-way transmission. The transmission gear 29 drives the sampling box 36 above the rotating column 31 to rotate to realize the replacement of the sampling box 36. As the sampling cylinder 1 continuously moves downward, the above sampling steps are repeated to realize multi-stage continuous interval sampling.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
