Description of the drawings
Fig. 1 is the stereochemical structure signal for the sample automatic ration dilution device that specific embodiment of the present invention provides
Figure；
Fig. 2 is the vertical view for the sample automatic ration dilution device that specific embodiment of the present invention provides.
Specific implementation mode
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
It please refers to Fig.1 with shown in Fig. 2, in the present embodiment, it includes pedestal 1 to provide a kind of sample automatic ration dilution device
And be set to sample disk component on pedestal 1, dilution disk component and control system, the sample disk component include sample disk 2,
Sample disk drive component 3, sampling arm 4 and sampling arm drive component 5, the sample disk drive component 3 drive sample disk 2 to rotate,
The bottom of the sample disk 2 is evenly equipped with several for placing the first operative position 6 of high concentration sample, and the one of the sampling arm 4
End connection sampling arm drive component 5, is provided with sampling probe 7 to other end energy automatic lifting, the side of the sample disk 2 is provided with
Cleaning device 8 for being cleaned to sampling probe 7, the sampling arm drive component 5 drive sampling arm 4 to do reciprocating rotary action
It is sampled.
The dilution disk component includes dilution disk 9, dilution dish driving component 10, dilution arm 11 and quantitative liquid feeding apparatus, institute
The side that dilution disk 9 is juxtaposed on sample disk 2 is stated, the sampling arm 4 is set between the dilution disk 9 and sample disk 2, institute
The bottom margin for stating dilution disk 9 is provided with several the second operative positions 12 for placing the empty test tube of dilution, second behaviour
Make more than the setting number of 12 to the first operative position 6 of position four, is diluted again for four high concentration samples specific position is secondary, and
Second operative position 12 includes close to the dilution position 13 of 11 side of dilution arm and close to the sample-adding position 14 of 4 side of sampling arm, institute
It states quantitative liquid feeding apparatus and is connected with the filling opening for diluting arm 11.The side of the dilution disk 9 is provided with pumping equipment 15.
