Description

[Detailed description of the invention] Conventional shakers are often vertical in which a shaker that performs a small rotational movement is rotatably attached to the head end of an eccentric drive shaft, and this type of shaker is mounted on the shaker. Since the center of gravity of the agitated liquid storage container to be placed is high, there is a risk that the container body may sway during shaking, and the shaker only performs a small rotational movement.

The present invention prevents the shaker from swinging by flattening the overall shape of the shaker and lowering the center of gravity, and also allows the shaker to be switched between small rotational motion and linear motion at will.

Next, the present invention will be explained with reference to figures showing embodiments.

Reference numeral 1 denotes a rectangular container with a shallow bottom and an open top.A horizontally rotating disk 3 is pivotally supported at the center of the inner bottom surface 2 of the case. A part of the upper running portion 8a of the endless belt 8, which is attached to the pulley 7 of the rotating shaft 6 of the horizontal motor 5 installed at one corner of the inner bottom surface 2, is fitted and press-welded to the upper running portion 8a. The disk 3 rotates accordingly.

Two rails 9 are installed in parallel at opposite corners of the cabinet 1, and four rollers 10 are mounted on the rails 9.
The rollers 10 of a linearly reciprocating vehicle 11 equipped with a linear reciprocating vehicle 11 are aligned so that the rollers 10 can freely reciprocate along parallel rails 9.

The linear reciprocating vehicle 11 is linearly reciprocated across a sliding tube 14 fitted around the outer periphery of two parallel shaft rods 13 supported at right angles between a frame 12 to which two rollers 10 are attached on both the left and right sides of the linear reciprocating vehicle 11. A rotating movement guide 15 that reciprocates in a direction perpendicular to the direction of movement of the motor vehicle 11 is fixed.

When the spiral rod 16 erected at an eccentric position on the upper surface of the disk 3 is rotatably connected to the rotary movement guide 15 and the motor 5 is rotated, the disk 3 moves into the annular groove 4 on the outer periphery of the endless belt 8. Upper running part 8
Since the parts a are fitted and pressed together, they rotate, and the spiral rod 16 erected at an eccentric position on the upper surface of the disc 3 makes a small turn.

In the figure, 17 is a power switch, 18 is a speed change knob, 19 is a timer, and 20 is a display section for the rotational speed of the disc 3.

Therefore, the spacer 2 is placed on the rotating motion guide 15.
1 and fixing the shaking container mounting base plate 22 with screws while separating the bottom surface of the base plate 22 from the frame 12,
Circling motion derivative 1 due to the small rotation motion of the spiral rod 16
A small turning movement of the helical rod 16 is achieved by a combination of the linear reciprocating movement along the parallel axis 14 of the helical rod 16 and the movement of the linear reciprocating wheel 11 that performs a linear reciprocating movement in a direction perpendicular to the direction of movement of the turning movement guide 15. Since the small turning movement continues unhindered, and the small turning movement of the shaking container mounting base plate 22 also continues, the flask containing the liquid to be stirred must be fixed on the base plate 22. For example, the liquid in the flask can be sufficiently stirred by applying vibrations.

If the container containing the liquid to be stirred is a test tube, it is more efficient to shake it by applying a linear reciprocating motion.
Remove the spacer 21 and attach the base plate 2.
2 is brought into close contact with both frames 21 and fixed with screws. Since the shaking container mounting base plate 22 is separated from the rotating movement guide 15, no turning movement is performed, and the linear reciprocating motion vehicle 11 is moved in a straight line. Since only the motion accompanying the motion is applied, the liquid in the test tube mounted and fixed on the shaking container mounting base plate 22 can be efficiently stirred.

The linear reciprocating motion of the shaking container mounting base plate 22 in the present invention is different from the simple reciprocating motion by a piston, for example, and is a small turning motion, so the degree of impact at the turning point of the linear reciprocating motion is minute. Even if the rotational speed of the disk 3 is increased rapidly, the test tube remains stable and there is no risk of liquid splashing out.

As described above, the present invention has the effect of efficiently stirring the liquid by selectively imparting a small turning motion or a linear reciprocating motion to the shaking container mounting base plate depending on the type of container containing the liquid to be stirred. In addition, since the entire container can be constructed flat, the container containing the liquid to be stirred can be placed at a lower position, which also has the effect of preventing the container from swinging.
