Oscillator

Abstract

The invention provides an oscillator. The oscillator comprises: an upper oscillator disc; a lower oscillator disc located directly below the upper oscillator disc; driving eccentric shafts, wherein one ends of the driving eccentric shafts are rotatably mounted on the upper oscillator disc, the other ends of the driving eccentric shafts are rotatably mounted on the lower oscillator disc, and the tail ends of the driving eccentric shaft downward extend out of the driving eccentric shafts and are fixedly connected with a driven pulley; driven eccentric shafts, wherein one ends of the driven eccentric shafts are rotatably mounted on the upper oscillator disc, and the other ends of the driven eccentric shafts are rotatably mounted on the lower oscillator disc; and a plurality of balancing weights respectively detachably mounted on the driving eccentric shafts and the driven eccentric shafts, wherein the upper part of every balancing weight is an arc-shaped cylinder, the upper end surface ofat least one of the balancing weights on the driven eccentric shafts is recessed downwards to form a plurality of parallel mounting grooves, and gravity center adjusting plates adapting to the mounting grooves are arranged in the mounting grooves. The oscillator avoids excessive oscillation or insufficient oscillation of a sample solution, and allows the collision force of drug particles or microorganisms in the solution to the wall of a bottle to be moderate.

Description

technical field [0001] The invention relates to the field of oscillator accessories, in particular to oscillators. Background technique [0002] The existing patent application number is CN200920112059.4 "torrent oscillator" patent document, which discloses a torrent oscillator, the center of gravity of the oscillator used in practice cannot be adjusted, when the liquid storage bottle When the liquid is too much or too little, the position of the center of gravity of a single counterweight will make the maximum height of the liquid in the liquid storage bottle float too low or too high, and the collision force between the drug particles or microorganisms in the liquid and the bottle wall will be too high. Small or too large, reduces the oscillation effect. Contents of the invention [0003] (1) Technical problems to be solved [0004] The object of the present invention is to provide an oscillator, which solves the problem that the center of gravity of the oscillator use...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an oscillator, which solves the problem that the center of gravity of the oscillator used by the existing oscillator cannot be adjusted. When there is too much or too little liquid in the liquid storage bottle, the single counterweight The position of the center of gravity will make the maximum floating height of the liquid in the liquid storage bottle too low or too high
