Sample bottle is placed on the carriage of being made up of upper tray and lower tray, and it is the sample bottle drive stepping motor that sample bottle drives power, and sample bottle drive stepping motor output shaft is fixedlyed connected with the carriage central shaft is concentric.The sample bottle drive stepping motor drives sample bottle and make circular motion on surface level.
The fixedly connected stopple coupon support in the rear end of stopple coupon, it is the stopple coupon drive stepping motor that stopple coupon drives power, the stopple coupon drive stepping motor is fixed on the automatic sampling apparatus base, and the output shaft of stopple coupon drive stepping motor connects screw mandrel, and screw mandrel cooperates with screw on the stopple coupon support.The stopple coupon drive stepping motor drives stopple coupon and does vertical movement.
Sample bottle has even number, and sample bottle holds testing sample solution and leacheate respectively, holds the sample bottle and the sample bottle interphase distribution that holds leacheate of testing sample solution.Stopple coupon alternately stretches into sample bottle that holds testing sample solution and the sample bottle that holds leacheate, has been infected with the stopple coupon of testing sample solution, cleans through leacheate, has avoided exerting an influence between the testing sample.
Stopple coupon is the suction spindle that is hollow needle.Liquid in the similar injection needle of suction spindle, sample bottle is sucked out from the hollow cavity of suction spindle.
After sample bottle held testing sample solution, film was sealed in its covering suitable for reading.Sealing film is used for dustproof and avoids sample oxidation by air, stopple coupon to puncture sealing film stretching in the liquid of sample bottle.
The interior liquid level of sample bottle that holds leacheate is higher than liquid level in the sample bottle that holds testing sample solution.With what guarantee that each sample bottle that holds leacheate can both be authentic and valid stopple coupon is carried out the cleaning of outside surface, take place with the situation of avoiding contaminated samples.
The utility model has the advantages that: the utility model can be automatically to two or more sample feedings, the sample introduction efficiency height, and the cost performance height, the parts of automatic sampling apparatus are domestic can be produced, low price, assembling is easily.
