Problems solved by technology
[0004] It compacts the soil samples by setting a blocking mechanism and an extrusion mechanism on the sampling device. However, when some soil samples with different depths need to be classified, the extrusion mechanism will compress the soil samples, resulting in Depth information is inaccurate, especially for sampling sites with relatively loose soil, the soil sample will be compressed by the extrusion mechanism, and the depth information of the sample cannot be judged well

The invention discloses a sampling device for detecting the organic matter content of ecological soil. The sampling device comprises a movable base; a supporting plate is arranged on the movable base; a sliding groove is formed in the supporting plate; a sliding block is movably arranged in the sliding groove; a mounting plate is arranged on the sliding block; a mounting block is arranged on the mounting plate; a sampling mechanism is arranged on the mounting block; the sampling mechanism comprises a plurality of sampling barrels arranged below the mounting block; and an auxiliary fixing mechanism for fixing a soil sample is arranged in each sampling barrel. According to the sampling device for detecting the organic matter content of ecological soil, the auxiliary fixing mechanisms are arranged, after sampling is completed, annular air bags are bulged through air pumps, soil samples at the two ends of the sampling barrels are extruded through the annular air bags, the two ends of the soil samples in the sampling barrels are compressed, then the outer sides of the soil samples are extruded through movable plates, the soil samples are relatively solidified and cannot collapse in the sampling barrels, and the soil samples can be conveniently discharged from the sampling barrels later.
Description
technical field [0001] The invention relates to the technical field of soil sampling, in particular to a sampling device for detecting the content of organic matter in ecological soil. Background technique [0002] Soil is an important part of the environment. Soil environment monitoring refers to determining the environmental quality (or pollution degree) and its changing trend through the determination of representative values of factors affecting soil environmental quality, continuous monitoring of soil environment, and national production. Construction plays a very important role. [0003] According to a soil sampler disclosed in the application number CN201811022859.7, it includes a handle, a pull rod and a sampling cylinder, the pull rod is fixed in the middle of the handle, and the axis of the pull rod is perpendicular to the axis of the handle, and the sampling cylinder is fixed on the pull rod away from the One end of the handle, the handle is provided with a cav...
