Driving wheel 451 and driven wheel 452 drive shaft 413 to rotate, and then make piece-like tube 412 that sampling head 411 be driven to decline, while liquid level passes
Liquid level information is transferred to 34 real-time display of liquid level display of control unit 3 by sensor, and operator can observe to obtain liquid level
Liquid level information in 34 real-time display of display, and then determine whether sampling head 411 drops to predetermined position；When determining sampling head
After 411 drop to predetermined position, sampling sharp-pointed tube release switch 32 is closed；Start non-quantitation automatic sampling switch 36 or quantitative automatic skewer
Sample switch 37 powers off magnetic powder cluth 6, while electromagnetic clutch 7 is powered, and starts pumping installations 42, and then pass through sample
41 pipette samples of device, then sample is exported by sample outlet pipe 43, the information of sampling amount can be transferred to control unit by flowmeter 8
3 35 real-time display of flow indicator, is supplied to operator's sampling amount information；It, can be repeatedly above-mentioned according to the demand of sampling
Operating process carries out the operation of different depth and different sampling amounts；Wherein, non-quantitation automatic sampling switch 36 can be used in controlling
The sample of the negated fixed volume of 41 skewer of sampling sharp-pointed tube, quantitative automatic sample switch 37, which can be used in controlling 41 skewer of sampling sharp-pointed tube, to be taken and sets in advance
Determine the sample of volume, such as presets the sample that skewer takes 500mm and 1000mm；Specifically, it can be set by programming
The primary quantitative automatic sample switch 37 of pressing represents skewer and takes 500mm sample, and quantitative automatic sample switch 37 represents skewer twice for pressing
Take 1000mm sample or other similar settings；Finally, starting sampling sharp-pointed tube packs up switch 33, magnetic powder cluth 6 is made to be powered,
Electromagnetic clutch 7 powers off simultaneously, closes pumping installations 42, rotates backward motor 44, pass through driving wheel 451 and driven wheel
452 drive shafts 413 rotate backward, and sampling sharp-pointed tube 41 are packed up, then sample outlet pipe 43 is packed up, complete sample process；In above-mentioned mistake
Cheng Zhong, can be by programming, making pumping installations 42 while rotating backward, by sampling sharp-pointed tube 41, pumping installations 42 and sample outlet pipe
Residual liquid flows back in liquid to be checked in 43, avoids liquid outflow drippage pollution environment.
