Small-size eddy type test tube vibrating and blending device

Abstract

The invention discloses a small-size eddy type test tube vibrating and blending device. The device comprises a blending box, a stepper motor is mounted at the bottom of the blending box, a main shaft of the blending box is connected with a transmission shaft through a flexible coupling, a rotary planetary gear is fixedly mounted in the middle of the transmission shaft, a first sleeve is movably mounted at the upper end of the transmission shaft, three or more planetary gear supports are welded to the outer wall of the first sleeve, a second sleeve is welded to the other end of each planetary gear support, and the middle of each supporting shaft is movably connected with the corresponding second sleeve. According to the small-size eddy type test tube vibrating and blending device, the supporting shafts of test tube blenders are mounted on a planetary gear, due to the fact that the planetary gear is meshed with a fixed planetary gear arranged on the inner wall of the blending box and the rotary planetary gear on the transmission shaft at the same time, when the transmission shaft is driven by the stepper motor to rotate, the test tube blenders can be made to revolve around the transmission shaft at the same time of rotating around the supporting shafts connected with the test tube blenders, and thereby automatic, rapid and uniform blending of liquid sample test tubes is achieved.

Description

technical field [0001] The invention relates to a small-sized vortex test tube oscillating and mixing device, which belongs to the technical field of experimental equipment. Background technique [0002] The mixing and separation of the sample mixture plays an important role in biological research. At present, most experimenters use manual mixing operations, which is not only easy to contaminate the test tube, but also time-consuming and laborious, especially when the sample mixture is collected in a large amount. Sometimes, it will lead to low experimental efficiency, high labor cost and high labor intensity. Contents of the invention [0003] The object of the present invention is to provide a small vortex type test tube oscillating and mixing device, which not only has simple structure, convenient operation, and uniform mixing, but also can mix test tubes of different specifications filled with liquid, so as to realize the batch and fast mixing of sample test tubes. , ...
