Specific embodiment

The utility model discloses a kind of laboratory dispersion machines, as shown in Figure 1, 2, including rack 1, screw-threaded shaft elevator structure, Stirring motor 3 and dispersion impeller 4, the screw-threaded shaft elevator structure include the lead screw 2-1 and nut 2-2 of complete cooperation, and the lead screw is perpendicular It is directly mounted on the rack, the upper and lower ends of the lead screw are rotated relative to the rack to be connected, and the nut is covered in the silk On thick stick, the fuselage of the stirring motor is fixedly connected with the nut.The main shaft of the stirring motor is also agitating shaft 3-1 vertical It extends downwardly, the dispersion impeller is coaxially mounted to the main the tip of the axis, one end of the lead screw and a big torsion decelerating motor 5 Output end be fixedly and coaxially connected, the big torsion decelerating motor is mounted on the rack.

The elevating movement that the stirring motor is realized using the screw-threaded shaft elevator structure can greatly reduce behaviour compared to manpower The labor intensity for making personnel can be driven stirring motor only by the power button for operating big torsion decelerating motor and do fortune up and down It is dynamic.Also, once stop the big torsion decelerating motor, the screw-threaded shaft elevator structure can be reliable self-locking, it is ensured that stirring motor Reliably stop at the desired position, therefore do not need that locking device is arranged again, also do not need counterweight, entire dispersion machine structure tends to Simply, small in size, light-weight, using flexible.

The big torsion decelerating motor has the small outstanding advantages of space hold, while realizing low speed, large torque pair Influence in terms of the space hold for increasing dispersion machine can be ignored.

The motor part of the big torsion decelerating motor uses overhead or underneath type, attached drawing institute with respect to speed reducing mechanism portion It is shown as overhead.When using underneath type, the space between lead screw and rack can be efficiently used, is conducive to reduce the dispersion The height of machine.

The controller (not shown) of the big torsion decelerating motor may be mounted in the rack.The stirring motor Speed setting controller (not shown) also may be mounted in the rack.On controller by manipulating the big torsion decelerating motor Start button, the stirring motor can be made to go up and down and stop at any time.
