Soil sample fall-preventing soil sampler for dry land

Abstract

The invention discloses a soil sample fall-preventing soil sampler for a dry land. The sampler comprises a handle, a vertical tube and a soil holder. The middle upper portion of the soil holder is cylindrical, the lower portion is cut to a bevel, a rectangular opening is formed in a bevel growing portion, and hooks are symmetrically arranged upward at two tips of the bottom end of the rectangular opening. The vertical tube is a hollow tube, the upper end of which penetrates through the handle to be opened outside and the lower end of which communicates with the soil holder. A hollow conical cavity is formed in the center of the soil holder, the top end of the conical cavity communicates with the bottom end of the vertical tube through a snap joint structure, and reverse small holes are formed in the periphery of the conical cavity. A pedal plate is arranged on the lower portion of the vertical tube. Scales are arranged on the left and right sides of the soil holder. Scale holes are symmetrically formed in the scale points at every 1-2cm. Scale rods are interspersed in the scale holes in the left and right sides of the soil holder. The scale rods are fixed on the vertical tube through ropes. The soil sample fall-preventing soil sampler for the dry land disclosed by the invention has the advantages of preventing soil from falling, accurately sampling and saving labor.

Description

Technical field [0001] The invention belongs to the technical field of soil extractors, and particularly relates to a soil extractor for preventing soil samples from falling in dry land. Background technique [0002] Earth borrowers are widely used in agriculture and mining. The prior art discloses a variety of soil extractors. However, in the practice of agricultural scientific research and production, when encountering sandy dry land soil, especially when sampling in particularly dry soil, there is no instrument that does not drop the soil during the upward extraction of the soil extractor. Falling soil causes inaccurate soil sampling, which has a great impact on subsequent soil determination. In addition, the existing soil extractor with a simple structure has the problem of high labor intensity and affects the sampling progress; the soil extractor with better soil extraction effect is often complicated in structure, large in volume, and inconvenient to carry. Therefore, th...

Problems solved by technology

But, in agricultural scientific research and production practice, run into partial sandy upland soil, when sampling especially in arid soil, also do not have a kind of utensil that the soil does not drop in the process of extracting the soil extractor upward
