Clamping slot type cutting ring soil sampler

Abstract

The invention discloses a clamping slot type cutting ring soil sampler including a cutting ring holder and a cutting ring; the cutting ring holder comprises a holder top and a clamping slot; the holder top is connected to the top of the inverted U-shaped clamping slot through a cylindrical rod; the cutting ring is embedded into the clamping slot, the top end presses against two symmetrical buckles and keeps a certain distance away from the bottom end of the inner side of the clamping slot; two inner side faces of the clamping slot each have an arc-shaped structure and are tightly fitted with the outer side face of the cutting ring, and the buckles are fixedly connected on the clamping slot; the buckles make the cutting ring keep a certain distance away from the bottom end of the inner side of the clamping slot, so that soil at the upper end of the cutting ring is prevented from making contact with the inner side of the upper part of the clamping slot, the cutting ring is more convenient to take down, and the soil in the cutting ring cannot be fractured during the taking-down process, so the integrity of the soil is kept, the reliability of the test is ensured, the time and labor waste of multi-time soil sampling is reduced, and the test efficiency is greatly improved; the buckles prevent generation of angle deflection and twisting in the process of soil sampling, so the accuracy and process of the test are improved; and the soil sampler also has the advantages of simple structure, low cost and practicality.

Description

technical field [0001] The invention relates to a slot-type ring-knife soil fetcher, which belongs to the technical field of test equipment. Background technique [0002] With the continuous growth of the team of scientific research personnel in our country and the continuous improvement and progress of scientific research technology, the design cost of the instrument is also increasing. In the selection of the instrument, we not only require the accuracy and durability of the instrument, but also improve the design of the instrument. Work efficiency, reduce labor and labor time input. General field ring cutter soil fetcher consumes labor force and wastes time, and the labor efficiency is not high. Contents of the invention [0003] The technical problem to be solved by the present invention is: to provide a slotted ring knife soil fetcher, which is practical, convenient, time-saving, labor-saving and high-efficiency, so as to solve the problems existing in the above-ment...
