Constant volume type undisturbed soil strong collector and using method thereof

Abstract

The invention discloses a constant volume type undisturbed soil strong collector and a using method thereof. The constant volume type undisturbed soil strong collector comprises a T-shaped lead screw, a pipe body (7) and a top anvil (4), wherein the top anvil (4) and the pipe body (7) are in multi-thread connection; the T-shaped lead screw consists of a handle (1) and a screw rod (2); the screw rod (2) on the T-shaped lead screw is in threaded connection with an internal screw hole (56) in the top anvil (4); a piston is arranged in the pipe body (7); the lower end of the pipe body (7) is connected with a drill bit (13). The collector adopts a split design, and each part can be flexibly detached and assembled, so that each functional part is conveniently intensified, a soil sample is conveniently collected and unloaded, the collector is particularly suitable for collecting samples containing gravelly soil, and the whole equipment is light, durable in use and easy to maintain. Moreover, the problems that the sampler is easily damaged when meeting gravels, the sample is difficultly unloaded and the original soil structure is difficultly kept in the sampling process in the prior art can be effectively solved.

Description

technical field [0001] The invention relates to a constant-volume undisturbed powerful soil collector, which belongs to the field of soil collection equipment. Background technique [0002] The collection of soil samples is a regular work in soil and environment research. The commonly used soil sample collection tool is the soil ring knife, which can not only collect the soil samples required for indoor analysis, but also has the function of determining the soil bulk density. However, the soil ring knife is not easy to unload after the soil sample is collected, and it is often necessary to destroy the original structure of the soil before taking out the soil, especially when the soil moisture content is low. However, many soil-related sample collections need to maintain the original properties of the soil. Not only that, in recent years, with the strengthening of the investigation and research on terrestrial ecosystems in my country, a large number of soil samples need to ...
