Oscillation extraction device applied to sample extraction of agriculture, forestry, animal husbandry and fishery

Abstract

The invention provides a specially-designed oscillation extraction device applied to sample extraction in agriculture, forestry, animal husbandry and fishery. A matched extraction tube is simple in structure, and can increase the extraction capacity, speed up the extraction process and facilitate sample comparison. The oscillation extraction device provided by the invention comprises an oscillator, a clamp assembly, and the extraction tube, wherein the clamp assembly and the extraction tube are assembled in a fixed manner; the oscillator drives the clamp assembly and the extraction tube to oscillate in the preset direction as a whole; the clamp assembly comprises a clamp base plate and a clamp unit. According to the oscillation extraction device provided by the invention, the clamp unit can be effectively used, so that the volume of the extraction tube within the allowable length range of the clamp unit is increased; two independent extraction spaces can be formed simultaneously, so that double-extraction of the same substance can be carried out, or comparison extraction for different substances can be carried out; therefore, the application range of the extracting device is definitely enlarged.

Description

technical field [0001] The invention relates to an instrument device in the field of agriculture, forestry, animal husbandry and fishery, in particular to a device for vibrating and extracting pesticide samples, biological samples, sediment samples and the like. Background technique [0002] The existing oscillation extractor in the field of agriculture, forestry, animal husbandry and fishery usually includes an oscillator, a clamp assembly, an extraction tube, the clamp assembly and the extraction tube are positioned and assembled, and the oscillator drives the entirety of the clamp assembly and the extraction tube to oscillate along the set direction. The device refers to the relevant components used to generate vibration, such as an oscillating motor, the so-called fixture unit is used to assemble on the oscillator, the so-called extraction tube is used to load the material to be oscillated and extracted, after the extraction tube is positioned and loaded on the clamp unit...

AI Technical Summary

Problems solved by technology

[0003] The defects of the existing oscillating extractors are: the structure of the extraction tube is simple, and the test tube is often used instead, and there is no specially designed extraction tube for some special applications

And the oscillation structure does not follow the oscillation principle, which makes the oscillation effect unsatisfactory, and it is difficult to achieve the expected extraction effect
