Description

[Detailed Description of the Invention] The present invention relates to a shaking mixer used in chemical analysis and the like.

In chemical analysis and the like, it is very common to mix and stir a large number of test solutions at the same time. Traditionally, this task involved shaking the test tube containing the test solution by hand, or inserting a glass rod or similar object into the test solution to stir it. For this reason, the work has to be carried out sequentially for each test tube, which requires a great deal of effort.Moreover, the stirring time varies from test tube to test tube, and as a result, various conditions such as reaction time and temperature become non-uniform. , the experimental accuracy will decrease.

The present invention aims to improve such inconveniences and provide a shaking mixer that can simultaneously mix and stir a large number of test solutions.

That is, the present invention consists of a holding stand for holding a large number of test tubes, a receiving tray on which the holding stand is removably mounted, a bearing at the center of the lower surface, a locking hole at one end, and a receiving tray that is loosely inserted into the locking hole. a machine body having a protruding rod, on which the saucer is mounted in a non-rotatable and horizontally movable manner;
This shaking mixer is provided in this machine body, and has an eccentric shaft inserted into the bearing at the tip of the rotating shaft, and an electric motor that rotates the position of the saucer by a minute amount.

The present invention will be explained in detail with reference to the embodiments shown below. Figure 1 is a plan view, Figure 2 is a front sectional view,
FIG. 3 shows a sectional view taken along the line -- in FIG.

Reference numeral 10 denotes a holding stand, which is made entirely of heat-resistant synthetic resin or the like and shaped like a disk, and its upper surface is provided with a number of vertical holes 14 into which test tubes 12 are inserted and held.
Reference numeral 16 denotes a saucer, which has a recess 18 on its upper surface, into which the holding base 10 can be removably fitted. A bearing 20 is provided at the center of the lower surface of the saucer 16, and a locking hole 22 is provided at one end. Reference numeral 24 denotes a machine body, on which a horizontal surface 26 is placed with a saucer 16 held down by a holding ring 28.
A protruding rod 30 protrudes from this horizontal surface 26, and the locking hole 2
2 is loosely inserted. 32 is an electric motor;
It is attached to the fuselage 24. An eccentric shaft 36 is provided at the tip of a rotating shaft 34 of this electric motor 32, and this eccentric shaft 36 is coupled to a bearing 20. 38 is an operation dial for the rotation speed regulator, and 40 is an operation dial for the time switch.
Operate the rotation regulator and time switch (both not shown in the drawing) connected to 2. 42 is a seismic rubber that absorbs vibrations of the aircraft body.

Since this shaking mixer has the above-mentioned configuration, the saucer 16 cannot rotate itself due to the action of the protruding rod 30 and the locking hole 22, but can move a minute amount in the horizontal direction. Therefore, when the electric motor 32 is operated, the saucer 16 is driven by the eccentric shaft 36, and its position is driven by a small amount of amplitude, thereby shaking the test tube 12 on the holder 10. In addition, the strength of shaking can be determined by operating the operation dial 38 and using the electric motor 30.
The shaking time can be adjusted by changing the rotation speed of the shaker, and the shaking time can be adjusted by operating the operation dial 40 and activating the time switch.

As is clear from the above, according to the present invention, a large number of test tubes can be stirred and mixed at the same time, which reduces the work effort, and also allows the various conditions for each test tube to be uniform, allowing the experiment to be carried out with ease. Improves accuracy. In addition, the present invention has a structure in which a large number of test tubes are held on a holding stand, and the holding stand is attached and removed together, so that operability is further improved. Furthermore, if a rotation speed regulator and a time switch are provided as in the above example, the intensity and time of shaking and mixing can be made uniform and reproducible, so that experimental accuracy can be further improved.
