Description

Vibration type centrifugal device Technical Field The invention relates to the technical field of centrifugal equipment, in particular to an oscillating type centrifugal device. Background At present, in the medical field, the blood is collected and then is separated by a centrifugal machine, so that the subsequent detection is convenient, the high-speed rotation of a rotor of the centrifugal machine is utilized to generate strong centrifugal force, the sedimentation speed of particles in the liquid to be detected is accelerated, and the buoyancy density and substances with different sedimentation coefficients in the liquid are separated.

However, in the process of centrifugation, sometimes the sample in the test tube needs to be sufficiently and evenly mixed by shaking and stirring in the middle, which leads to frequent transfer of the test tube between the centrifuge and the shaking stirrer by operators, which not only affects the preparation efficiency, but also easily causes pollution and affects the subsequent inspection. Disclosure of Invention The invention solves the problem of providing the oscillating type centrifugal device capable of simultaneously meeting the centrifugal and oscillating operations on a sample. In order to solve the problems, the invention provides an oscillating type centrifugal device, which comprises a main frame body, a main power source for driving the main frame body to rotate, an oscillating assembly and a sliding assembly, wherein a plurality of sub frame bodies which are circumferentially distributed are arranged on the main frame body, a rest part for fixing a sample is arranged on each sub frame body, a transmission rod is arranged on each sub frame body, the oscillating assembly comprises an eccentric sleeve and an oscillating power source, the sliding assembly is used for driving the oscillating assembly to move towards the transmission rod so that the eccentric sleeve is inserted by the transmission rod, and the oscillating power source is used for driving the eccentric sleeve to rotate. The technical scheme has the advantages that the main frame body is driven by the main power source, so that samples on the sub-frame body can rotate along with the main frame body to realize a centrifugal function, meanwhile, due to the arrangement of the vibration assembly and the sliding assembly, after the samples are temporarily centrifuged, the eccentric sleeve can move towards the transmission rod under the driving of the sliding assembly until the transmission rod is inserted into the eccentric sleeve, and then the vibration power source drives the eccentric sleeve to rotate, so that the samples on the sub-frame body vibrate along with the eccentric sleeve to be uniformly mixed. After the vibration is finished, the sliding component drives the eccentric sleeve to reset, and the sample can be subjected to centrifugal operation continuously according to the requirement. Compared with the prior art, the scheme can realize centrifugal and vibration operation simultaneously without transferring samples, has high preparation efficiency and can not cause pollution.
