Ring-knife soil sampler and use method thereof

Abstract

The invention provides a ring-knife soil sampler and a use method thereof. The ring-knife soil sampler comprises a sampling head and a handle mechanism, wherein the sampling head comprises a ring-knife fixing cover, a ring-knife, a baffle lock ring, a ring-knife baffle and a fixed base, wherein the ring-knife fixing cover is a cylinder of which both ends and side walls are provided with openings, the ring-knife is connected with the inside of the ring-knife fixing cover; the upper part of the ring-knife fixing cover is a circular ring body which is connected with the lower end of the fixed base; the fixed base is connected with the handle mechanism, the handle mechanism is connected with an external driving motor; the baffle lock ring is sleeved on the circular ring body of the ring-knife fixing cover and rotatably connected with the lower end of the fixed base; the baffle lock ring and the circular ring body are both provided with notches, the notch of the circular ring body and the openings are on the same side; and the ring-knife baffle is arranged at the opening of the side wall of the ring-knife fixing cover, one end of the ring-knife baffle is clamped on the baffle lock ring, and the other end of the ring-knife baffle is connected with the lower end of the ring-knife fixing cover. The ring-knife soil sampler has the advantages of convenience in operation, simpleness, rapidness, convenience and the like.

Description

technical field [0001] The invention relates to the technical field of soil sampling, in particular to a ring cutter soil sampler and a using method thereof. Background technique [0002] The collection of soil samples is a basic work of scientific researchers engaged in agricultural research, and it is also an important part of soil testing. In recent years, with the rapid development of precision agriculture in my country, the research on the collection of soil information has gradually begun to conduct in-depth research. At present, the commonly used soil collection methods can be divided into manual collection and mechanized collection. Mechanized collection equipment is complex and expensive; manual collection commonly uses small soil shovels, tubular sampling drills and ordinary soil drills. The small soil shovel is time-consuming and labor-intensive, and the labor intensity is high; the tubular sampling drill inserts the sampler into the soil, and the soil is concent...

Problems solved by technology

At present, the commonly used soil collection methods can be divided into manual collection and mechanized collection. Mechanized collection equipment is complex and expensive; small soil shovels, tubular sampling drills and ordinary soil drills are commonly used for manual collection.

The small soil shovel is time-consuming and labor-intensive, and the labor intensity is high; the tubular sampling drill inserts the sampler into the soil, and the soil is concentrated in the sampling tube through rotation and extrusion. After the soil layer is pulled out, the sampler is separated to take out the soil. , The soil is difficult to take out; ordinary soil drills are likely to mix the soil and lose part of the surface soil sample

At present, there is no universal, quantitative, fast and convenient soil sampler, which has large soil sampling errors and heavy workload
