Reciprocating oscillation machine sample workpiece mounting and fixing device

Abstract

The invention relates to sample placing and fixing techniques of a reciprocating oscillator, in particular to a sample placing and fixing device of a reciprocating oscillator The invention comprises a pallet which is arranged on an oscillating shelf of an oscillator, the oscillating shelf is connected with an oscillating source of the oscillator, an outward B surface of a primary-secondary sticky fastener is fixed on the upper surface of the pallet; one or more than one bags for placing containers, which comprise a bag base, a bag wall and a bag opening, and the bag base of the placing bag is composed of an outward A surface of the primary-secondary sticky fastener, the bag wall is a cylindrical structure made of cloth, and an elastic belt or a tether is arranged at the bag opening; the A surface and the B surface of the primary-secondary sticky fastener can be sticky connected or disconnected with each other for assorted usage. The invention uses the primary-secondary sticky fastener as a fixing tool, takes the elastic belts with different width and elasticity as materials for making the placing bags, and fixes the containers on the pallet, thus greatly raising the fixing level. The invention brings multiplied increase to experimental efficiency, and increases the freedom degree of placing samples, and the production and maintenance of the invention is easy.

Description

technical field [0001] The invention relates to sample placement and fixation of a reciprocating oscillator in a laboratory, in particular to an improved device for sample placement and fixation in the oscillator. Background technique [0002] The reciprocating oscillator is a common laboratory equipment, mainly used to fully mix solids and liquids or liquids and liquids. It has a wide range of applications in soil chemical property analysis, various chemical experiment analysis, and water quality identification. Applications. Especially in the analysis and determination of soil physical and chemical properties, due to the characteristics of soil physical properties (solid state), before entering the instrument test, it is often necessary to use designated chemical reagents to extract the nutrients or substances that need to be measured in the soil, in liquid form. For the determination, a shaker is required to thoroughly mix the soil sample with the chemical reagents. For...

Problems solved by technology

However, these two current methods still have certain shortcomings in the process of use: first, the shrapnel-type fixing method has strict restrictions on the placement of samples, and seriously affects the number of samples placed, so that the number of samples in one oscillation is limited. To a large extent, the use efficiency is greatly reduced. Although the spring-type fixing method has greatly improved the placement restrictions and increased the freedom of sample placement, but because the volume of the spring itself occupies a certain space on the pallet, this is convenient. The increase in the number of samples placed is small, and it does not contribute much to improving the efficiency of the experiment; secondly, since most of the solutions in the container are acid, alkaline or solutions containing a certain amount of salt, it is inevitable to spill them during the shaking process. On the metal shrapnel or springs used for fixing, the shrapnel or springs may be corroded by the solution over time and may be damaged, so that the fixing effect cannot be exerted. In addition, the replacement of these two kinds of fixing devices requires high cost and the process is cumbersome. It is difficult for non-professionals to complete, which greatly increases the cost of using the oscillator
