A device and method for collecting and storing microorganisms in frozen soil

Abstract

The invention discloses a device and method for collecting and storing microorganisms in frozen soil. The cantilever is released, the cantilever moves downward under weight, the drilling assembly drills the well and breaks the soil vertically, and the frozen soil isolation assembly and the drilling assembly move down synchronously to break the drilling assembly. Frozen soil isolation prevents cross-contamination; the drilling assembly moves down to the deepest position and stops rotating, connects the frozen soil isolation assembly with the power assembly of the drilling assembly, uses the rotating crankshaft of the drilling assembly to drive the rotation of the frozen soil isolation assembly, and uses the power assembly to drive the frozen soil isolation assembly The frozen soil storage point on the frozen soil is opened; the power assembly of the drilling assembly is stopped from rotating, and during the inertial rotation of the frozen soil isolation assembly, the power assembly drives the frozen soil storage point on the frozen soil isolation assembly to close; the cantilever is lifted to drive the drilling assembly and The frozen soil isolation components move up synchronously to complete the collection and induction of frozen soil; the invention realizes the collection and storage of frozen soil and its internal microorganisms during the drilling and crushing of frozen soil, improves efficiency and avoids cross-contamination of frozen soil microorganisms.

Description

technical field [0001] The invention relates to the technical field of frozen soil microorganism collection, in particular to a frozen soil microorganism collection and storage device and method. Background technique [0002] Frozen soil refers to various rocks and soils that are below zero degrees Celsius and contain ice. Generally, it can be divided into short-term frozen soil (hours / days or even half a month) / seasonal frozen soil (half months to several months) and permafrost (also known as permafrost, which refers to freezing that lasts for two or more years) Due to its unique geographical and climatic characteristics, frozen soil contains a large number of biologically active microorganisms in various forms and ecological groups, and has survived for thousands of years or even millions of years. The genetic characteristics and physiological and biochemical mechanisms of adaptation to the environment. Carrying out research on permafrost microorganisms will help protect ...
