Problems solved by technology
[0002] Due to the high water content of wetland soil, its fluidity is stronger than that of ordinary soil. When the soil sample is taken out after the sampling is completed, the soil sample may be detached due to insufficient friction between the soil and the sampler.

Embodiment Construction
[0015] In order to clarify the technical scheme and technical purpose of the present invention, the present invention will be further introduced below in conjunction with the accompanying drawings and specific implementation methods.
[0016] As shown in the figure, a wetland soil sampler includes an inner tube 1 and an outer tube 2:
[0017] The inner tube 1 is a round tube, and the lumen of the inner tube 1 is divided into two parts, the superior arc portion 21 and the inferior arc portion 22, through a partition, the superior arc portion 21 can be set as a cavity or a solid body, and the inferior arc portion The arc portion 21 is a cavity with a lower opening;
[0018] Described outer tube 1 is a superior arc-shaped tube stuck on the outer wall of inner tube 2, and the arc center of outer tube 1 is coincident with the center of circle of inner tube 2, and it is fixed by the central axis protruding from the center of inner tube 1, and Rotating with the central axis as the c...

The invention discloses a wetland soil sampler, which is characterized in that it includes an inner pipe and an outer pipe. The inner pipe is a round pipe, and the pipe cavity of the inner pipe is divided into a major arc part and a minor arc part. The major arc part is a hollow cavity or an entity. The minor arc part is a hollow cavity with an open bottom. The outer pipe is a major arc-shaped pipe stuck in the outer wall of the inner pipe. The arc center of the outer pipe arc coincides with the circle center of the inner pipe. The outer pipe has a closed bottom, and the bottom plate of the outer pipe is a major arc-shaped closing plate. The wetland soil sampler disclosed in the invention adopts the inner pipe and the outer pipe in a form of casing pipes, employs the outer pipe bottom plate to cut off a soil sample in the inner pipe, and the cavity for soil sample collection is closed at the same time, thus effectively avoiding the occurrence of soil sample slippage.
Description
technical field [0001] The invention belongs to wetland sampling equipment, in particular to a wetland soil sampler. Background technique [0002] Due to the high water content of wetland soil, its fluidity is stronger than that of ordinary soil. When the soil sample is taken out after sampling, the soil sample may be detached due to insufficient friction between the soil and the sampler. Contents of the invention [0003] The technical purpose of the present invention is to solve the problems existing in the prior art and provide a wetland soil sampler with simple structure and convenient sampling. [0004] Technical scheme of the present invention is: [0005] A wetland soil sampler is characterized in that it includes an inner tube and an outer tube, the inner tube is a circular tube, and the lumen of the inner tube is divided into two parts, a superior arc part and a inferior arc part, through a partition, and the superior arc part is divided into two parts. The arc ...
