When in use, the ring knife is smashed into the soil by the gravity of the pull hammer, and the rubber pad is used for buffering to ensure that the soil layer structure is not damaged. When sampling, the excavation of the soil profile is avoided, and the damage to the ecological environment is small. Compared with the traditional sampling method, the sampling time is shortened, and manpower and material resources are saved. In terms of sampling method, vertical soil sampling replaces horizontal soil sampling, and the soil sample taken is more representative. Compared with the traditional ring knife handle, the safety performance is higher, but the sampling ring knife has the following disadvantages in actual use:
[0004] When the sampling ring knife is in use, the pull hammer is pulled upward, and then the ring knife is smashed into the soil by relying on the gravity of the pull hammer, so as to sample the soil. During a sampling process, it may be necessary to pull the pull hammer several times to smash the ring knife into the appropriate depth. The working efficiency is slow, and it is not easy to take the soil out of the ring knife after the sampling is completed. Therefore, the utility model provides a sampling ring knife.
