Problems solved by technology

[0004] The technical problem to be solved in the present invention is: the shaking method in the existing biochemical test generally uses the contact object to stir, causing materials to adhere to the contact object after mixing, causing inaccurate proportioning to affect the experiment; now Some shakers have a single shaking method, and cannot imitate the trajectory of manual shaking, cannot be applied to a variety of different phases to be shaken, and the shaking effect is relatively poor

Embodiment （ 1

[0037] In the biological fermentation experiment, the water and the lactic acid bacteria liquid are mixed according to the ratio of 100:1. Since the bacteria liquid and the water are both in liquid state and are relatively easy to mix, a circular motion with a small centrifugal force is sufficient. see Figure 4 , the two ends of the connecting rod 3 are respectively connected to the crank 4 and the rocker 5, the radius of rotation is selected to be the smallest, and the radius of rotation of the crank 4 and the rocker 5 is the same, combined figure 1 , Figure 4 , the tray 6 and the container 1 are installed on the connecting rod 3 . Due to the small centrifugal force and differential speed generated when the radius is small, the water and alcohol are mixed evenly after 5 minutes.

Embodiment （ 2

[0039] In the detection of feed crude protein, it is necessary to mix water and sodium hydroxide according to the ratio of 100:40. Since water is liquid and potassium chloride is solid, the shaking range required for dissolution is relatively large, so a large centrifugal force is required. circular motion. The installation method is as follows image 3 As shown, the two ends of the connecting rod 3 are respectively connected to the crank 4 and the rocker 5, the radius of rotation is selected to be the largest, and the radius of rotation of the crank 4 and the rocker 5 is the same, and the tray 6 and the container 1 are installed on the connecting rod 3 . Due to the large centrifugal force and differential speed generated when the radius is large, the water and potassium chloride are evenly mixed after 10 minutes.

Embodiment （ 3

[0041] In the flocculation experiment, the polyacrylamide and water were mixed according to the ratio of 3:100. Since the polyacrylamide was partially dissolved, the solution was viscous. A horizontal one-way shaking method is required, that is, the inertia of the solute and solution movement is used to generate a differential speed to accelerate the dissolution. The installation method is as follows Figure 5 As shown, the two ends of the connecting rod 3 are respectively connected to the crank 4 and the rocking bar 5, the radius of rotation of the crank 4 is selected to be the smallest, the radius of rotation of the rocking bar 5 is larger than that of the crank 4, and the tray 6 and the container 1 are placed on the top of the rocking bar 5. During operation, the crank 4 moves in a circle, and the rocker 5 moves back and forth along the arc track. The arc shaking of the rocker 5 during operation will cause the solvent and the solute to produce an inertia differential, and ...

Abstract

The invention relates to a shaking machine for a biochemical test. The shaking machine is characterized by comprising a frame (2), wherein a motor (7) is fixedly arranged on the frame (2); an output shaft of the motor (7) is vertically upward and connected with a coupling (8); the coupling (8) is connected with a crank (4) horizontally arranged; the crank (4) is also hinged with a connecting rod (3); the connecting rod (3) is also hinged with a rocking bar (5); the rocking bar (5) is also hinged with the frame (2); a tray (6) is fixedly arranged above the connecting rod (3) or the rocking bar (5); a container (1) is fixed on a clamp (9) on the tray; and the motor (7) is started, the output shaft drives the crank (4) to rotate around the coupling, the crank (4) drives the end point of the connecting rod (3) connected with the crank (4) to synchronously rotate, and the connecting rod (3) drives the rocking bar (5) to rotate or swing around a hinge point of the rocking bar (5) and the frame (2).

Description

technical field [0001] The invention relates to a shaker, in particular to a shaker for biochemical tests and a shaker method thereof, which is used for mixing multiple reagents in biochemical experiments, and belongs to the technical field of mechanical devices. Background technique [0002] At present, in biochemical experiments, there will be a variety of materials with different phases that need to be mixed uniformly. Generally, stirring is carried out by contact objects such as glass rods, paddles or rotors, but after mixing, materials will adhere to the contact objects, resulting in inaccurate proportioning and affecting the experiment. Therefore, it is an ideal way to shake well without contacting the material. Most of the shakers used in the laboratory or factory are simple rotary or one-way shaking type, which is aimed at a single phase of mixing, and the rotary type is mostly used for mixing liquid-liquid or solid-liquid phase materials, and one-way shaking type. ...
