Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to a sampling equipment for wetland ecological restoration. Background Art

[0002] In wetland ecological restoration, soil sampling equipment is a common tool used to collect wetland soil samples. A common wetland soil sampling equipment is a soil drill. A soil drill usually consists of a drill rod, a drill bit and a handle. During operation, first select a suitable location to determine the drilling point, then insert the drill rod into the ground, and drive the drill bit to drill out the soil. The length of the drill rod can be flexibly adjusted as needed to adapt to drilling at different depths. After the drilling is completed, the handle can be used to pull the drill rod upward to take out the soil sample. When collecting wetland soil samples, it is necessary to pay attention to selecting representative sampling points and ensure that the sampling equipment is completely clean to avoid contaminating the sample. The collected soil samples can be analyzed in terms of physical properties, chemical composition and microorganisms to evaluate the quality and suitability of wetland soil and provide a basis for wetland ecological restoration.

[0003] The prior art provides an ecological soil remediation sampling device for wetlands (Announcement No.: CN115615743B), which includes a frame, a sampling sleeve, a sampling mechanism, a dewatering unit and a driving mechanism. The sampling mechanism can introduce external soil into the sampling sleeve, and the power component can switch the sampling unit between an extended state and a retracted state. The dewatering unit can receive the soil introduced into the sampling sleeve by the sampling mechanism and dewater the soil; when in use, the sampling mechanism can introduce external soil into the sampling sleeve, and when the sampling sleeve rises to separate from the soil, the driving mechanism will drive the dewatering unit to dewater the internal soil, so there is no need to set up an additional dewatering device for dewatering operations, the operation is relatively simple, and the work efficiency is high.

[0004] But the device still has the following defects:

[0005] When the device is used, when taking out soil samples, it is not possible to separate the soil at different depths. Since the soil at different depths cannot be effectively separated, the soil samples at different depths may be mixed together during sampling. Such mixing may lead to misunderstandings and deviations, making the assessment and analysis of soil properties inaccurate. Therefore, we need to propose a sampling device for wetland ecological restoration. Utility Model Content
