Ring cutter and baffle combined closed soil sampler and application thereof

Abstract

The invention relates to a ring cutter and baffle combined closed soil sampler and application thereof. The soil sampler is composed of a handle, an extension rod assembly, a ring cutter cylinder and a sampling head, wherein the handle, the extension rod assembly and the ring cutter cylinder are sequentially connected, the sampling head is of a hollow structure, one end of the sampling head is connected with the ring cutter cylinder, the other end is a soil sampling opening, the cross section of the inner side of the soil sampling opening is round, a baffle mechanism is arranged on the inner side wall and composed of multiple triangular or sectorial baffles, the baffles are distributed in the circumference of the inner side wall of the soil sampling opening, the bottom edges of the triangular baffles or the arc edges of the sectorial baffles are connected with the inner side wall of the soil sampling opening, and the vertexes overlap on the circle center of the cross section of the inner side of the soil sampling opening. Compared with the prior art, the soil sampler is convenient to carry, capable of accurately quantifying soil layered thickness and collecting soil samples of a hard soil layer and a soft soil layer and particularly suitable for collecting coastal salt marsh soil, sludge, slime and other kinds of soil high in water content.

Description

technical field [0001] The invention belongs to the field of soil fetching devices, and in particular relates to a ring-knife combined baffle closed type soil fetching device which is convenient to carry and can accurately quantify the depth of soil stratification and its application. Background technique [0002] Earth borrowers and their operating methods are essential in ecology, soil science research, and engineering geological surveys. At present, open-type soil fetchers are generally used to collect soil samples from hard soil, soft soil and ultra-soft soil layers, but the effect of soil sampling on soils with high water content is not good, and the existing soil fetches cannot accurately measure soil samples. The depth of the depth of the layer, the soil samples of each soil layer cannot be accurately quantified after the soil is taken, and the secondary interference and loss are prone to occur when the soil samples are transferred. These cannot meet the fine soil sam...

AI Technical Summary

Problems solved by technology

The earth taker is equipped with a baffle frame to prevent the baffle from falling down. However, when soil is taken, the soil samples will be diverted, and the soil samples at the corresponding baffle frame cannot enter the soil getter, resulting in a large flow of water after each soil fetch. There is residual soil, and the soil is not clean
