Cutting ring sampler capable of simultaneously using multiple cutting rings for sampling

Abstract

The invention relates to a ring cutter sampler which can simultaneously use multiple ring cutters for sampling, comprising a female rod (3) and a drill bit (7), the drill bit (7) is installed at the bottom end of the female rod (3), and other The feature is that: the female rod (3) is provided with a plurality of slots at different positions along the axial direction, and a ring knife is placed in each slot, and the plurality of ring knives realize simultaneous sampling of soil at different soil depths.

Description

technical field [0001] The invention relates to the field of soil science experimental research equipment, in particular to a ring knife sampler which can simultaneously use a plurality of ring knife samples. Background technique [0002] The soil ring knife is often used to measure some soil properties such as soil bulk density, moisture content, density, porosity, moisture characteristic curve, etc., and plays an important role in soil science research. Common ring knives are mainly metal rings, and their volume is generally divided into 100cm 3 and 200cm 3 two kinds. At present, the common soil ring knife sampler mainly uses a hammer to drive the ring knife into the soil, and then takes the ring knife out for analysis and experiments. This soil sampling method has problems such as large disturbance of the original soil by hammering, time-consuming and laborious, large land damage area, and the ring knife is not easy to take out when deep soil sampling is performed. ...

AI Technical Summary

Problems solved by technology

[0004] The present invention designs a ring knife sampler that can use multiple ring cutters to sample at the same time. The technical problem it solves is the repetitive and cumbersome process of using a single ring cutter to sample soil at different depths in the prior art, and the existing ring cutter sampling The drill bits of the drill are all ring-edge structures, which makes the sampling process more laborious and inconvenient to the sampling process
