Soil microorganism measuring sampler

Abstract

The invention relates to the technical field of soil sampling, in particular to a soil microorganism measuring sampler, a sampler body comprises a barrel shell, a lifting mechanism and a conical barrel, a semicircular pressing plate is arranged at the upper end of the barrel shell, a transverse plate is fixedly mounted at the upper end of the semicircular pressing plate, a transverse rod is fixedly mounted at a barrel opening of the lower end of the barrel shell, and the transverse rod transversely penetrates through the interior of the conical barrel; an abutting plate is fixedly installed in the middle of the transverse rod, a leakage hole is formed in the abutting plate, and three limiting assemblies are arranged at the positions, close to the lower middle end, of the inner surface of the barrel shell at equal intervals and are horizontally arranged; the limiting assembly comprises an L-shaped clamping plate, a rotating rod and two sets of semicircular elastic pieces, and the turning point position of the L-shaped clamping plate is movably installed in the barrel shell through the rotating rod. According to the device, the loss of collected soil can be reduced, the influence on the detection effect in the soil is reduced, grass winding in water is reduced, sampling and collection of the device body are facilitated, and the collection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of soil sampling, in particular to a sampler for measuring soil microbes. Background technique [0002] In natural science research, it is necessary to collect and sample soil, air, water and other substances, and then move the samples to the laboratory for analysis and testing. Both air and water are substances that are relatively easy to collect, and samples can be collected with only simple equipment. In soil and water environment research, it is often necessary to take soil samples from underwater sediments such as rivers, lakes, and wetlands. [0003] The existing patent (notification number: CN202153188U) underwater soil sampler includes a handle, a sampler and a push rod. The sampler is a hollow stainless steel tube with openings at both ends. The rod is matched with the sampler, and the soil in the sampler is pushed out through the push rod to avoid damage to the soil structure. [0004] In the pr...

Problems solved by technology

[0005] 1. When sampling the soil in an ecological lake, because the underwater soil sample has a high moisture content and is fluid, if the soil is mixed with too much water, the sediment disturbance will occur due to the influence of the water body, which will not only increase the The weight of the sample soil and the separation and loss of the sample cannot achieve the effect of quantitative sampling, thus affecting the overall sampling effect

[0006] 2. Due to the fluidity of the lake water, the aquatic plants growing in the lake will also sway under the action of the lake water. When the sampler is taken from the bottom of the lake after sampling, the body of the sampler may be bound by the aquatic plants, making it difficult to extract the sampler. thus affecting soil sampling efficiency
