Detailed implementation manners

[0021] Referring to Figures 1 - 5 as shown, the technical solution adopted in this detailed implementation manner is as follows: It includes a push rod 5. One end of the push rod 5 is welded with a transverse support rod 3, and the other end of the push rod 5 is welded with a sampling cylinder 6. The middle part of the top of the transverse support rod 3 is penetrated by a rotary rod 2, and the rotary rod 2 sequentially penetrates through the transverse support rod 3, the push rod 5 and the sampling cylinder 6. A push plate 7 is welded at the inner cavity of the sampling cylinder 6 where the rotary rod 2 is located. The other end of the rotary rod 2 is welded with a rotary handle 1. An airbag assembly 9 is arranged in the inner cavity of the rotary rod 2, and the airbag assembly 9 is located inside the push plate 7. The airbag assembly 9 includes a ventilation pipe 92. A check valve 91 is installed at the top end of the ventilation pipe 92. The bottom of the ventilation pipe 92 is communicated with an airbag 94 through a catheter 93, and the airbag 94 is located inside the push plate 7.

[0022] More specifically, hand grips 4 are arranged at both the left and right ends of the transverse support rod 3, and the hand grips 4 are made of rubber material. The hand grips 4 can increase the holding force of the staff and prevent the staff from loosening and slipping.

[0023] More specifically, a soil sampling groove A for facilitating the extraction of soil and the observation of soil is opened on the side of the lower part of the sampling cylinder 6.

[0024] More specifically, rotary engaging teeth 8 are arranged on the inner wall of the push rod 5, and the outer wall of the sampling cylinder 6 and the inner wall of the push rod 5 are meshed with each other through the rotary engaging teeth 8. By arranging the rotary engaging teeth 8, when the rotary handle 1 rotates, the rotary rod 2 can move inward.

[0025] More specifically, a number of air bags 94 are provided, and an intercommunication conduit 95 is provided between two adjacent air bags 94. Through the intercommunication conduit 95, the pressure inside each air bag 94 can be made the same, so that the expansion and contraction degrees of the multiple air bags 94 are consistent.

[0026] More specifically, a cleaning surface layer 94-1 is provided on the outer side of each air bag 94. The cleaning surface layer 94-1 can increase the friction with the inner wall of the sampling cylinder 6, so as to better clean the sampling cylinder 6 and ensure that the soil is not contaminated.

[0027] More specifically, the bottom end of the rotating rod 2 is welded to the push plate 7, and the top end of the rotating rod 2 is welded to the rotating handle 1. The rotating handle 1, the rotating rod 2 and the push plate 7 are welded together, so that they can rotate integrally, thereby ensuring their mechanical conductivity.

[0028] The working principle of the present utility model: When soil sampling operation is required, the staff can use this soil sampler for sampling. When in use, the staff should first select a suitable soil position, then align the sampling cylinder 6 with the position, then hold the hand-held grip 4 and push the hand-held grip 4 downward to insert the sampling cylinder 6 into the soil. After taking out the soil, the staff can rotate the rotating handle 1, drive the rotating rod 2 and the push plate 7 to push downward through the rotating handle 1, and use the push plate 7 to push the soil out of the sampling cylinder 6. When the sampling cylinder 6 needs to be cleaned, the staff only needs to inflate the air bag 94 through the air pipe 92 to make the air bag 94 expand, and use the air bag 94 and the cleaning surface layer 94-1 to friction-clean the inner wall of the sampling cylinder 6. Then, the staff only needs to clean it with clean water. Among them, when inflating, the check valve 91 will prevent gas leakage. After use, the staff only needs to open the check valve 91 to discharge the gas and complete the contraction operation of the air bag 94.

[0029] The above is only used to illustrate the technical solution of the present utility model and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present utility model should be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solution of the present utility model.
