The present invention proposes the first embodiment, and a kind of sample preparation instrument comprises sample fixing device, running gear and drive unit.As shown in Figure 1, wherein:
(1) sample fixing device 1 fixed sample.
In the present embodiment, sample fixing device 1 can be positioned on running gear 2 or under, also can be with running gear 2 in same level position, to the annexation of sample fixing device 1 and running gear 2 without particular restriction.Preferably, sample fixing device 1 is positioned on same level position with running gear 2, and this technical scheme has reduced the center of gravity of sample preparation instrument, thereby while making sample preparation instrument work, the Oscillation Amplitude of complete machine is little.The structure of sample fixing device 1 is without particular restriction, and it can be and can be used for arbitrarily holding or the device of fixed sample, as: Reagent Tube, reagent bottle, grinding pot etc.
(2) running gear 2 drives sample fixing device 1 to move.
Running gear 2 in the present embodiment is without particular restriction, and running gear 2 can be for connecting the device of sample fixing device 2 and drive unit 3 arbitrarily.This device can be converted to straight line or curvilinear motion by the motion of drive unit 3, and while exporting the motion-promotion force of circumferential motion such as drive unit 3, running gear 2 is converted to translational motion or fan shape moving etc. by circumferential motion; Or directly motion-promotion force is passed to sample fixing device 1, such as drive unit 3 is exported the motion-promotion force of fan shape moving or circumferential motion, running gear 2 directly changes motion-promotion force to sample fixing device 1, and sample fixing device 1 does fan shape moving or circumferential motion.
(3) drive unit 3 provides running gear 2 motion-promotion forces.
In the present embodiment, described drive unit 3 comprises motor, also can comprise voltage current adapter.Wherein, described motor is without particular restriction, voltage current adapter is the required size of motor or change frequency by the voltage of input or current conversion, and voltage or electric current (comprising size and change frequency) after conversion are inputed to motor, this motor according to input voltage or electric current with certain rotation speed operation, thereby provide running gear 2 motion-promotion forces; In addition, this motor also can move with constant rotating speed, thus the power that provides running gear 2 to move.
In the present embodiment, running gear 2 is connected respectively with sample fixing device 1 and drive unit 3, and running gear 2 is positioned on same level position with drive unit 3.Shown sample fixing device 1 is positioned in same level with running gear 2 or sample fixing device 1 is positioned at the top of running gear 2.The center of gravity of the sample preparation instrument in the technical program is low, thereby while making sample preparation instrument work, the vibration of complete machine is little, noise is low, and the technical scheme of the present embodiment can be according to the time of drive unit 3 rotational frequencies decision sample preparations, thereby make the effect of sample preparation more controlled, also the vibration that is sample preparation instrument complete machine is little, makes the effect of sample preparation more controlled, greatly improves the quality of sample preparation.
For running gear 2, the present embodiment provides an example, and as shown in Figure 2 a, running gear 2 comprises transmission mechanism 21 and vibration abatement 22.Wherein:
