s18: enabling the injection pump to work by the DCS control system according to the sample weighing data information in the step S16, and adding an appropriate amount of basic lead acetate into the sample cup;
s19: automatically turning off the injection pump after obtaining a proper amount of sample solution by dosing and weighing a precision balance;
s20: after the medicine is filled, the second pneumatic lifting platform descends, and the conveying chain conveys the sample cup to a grinding and stirring position;
s21: the automatic grinding stirrer is used for crushing and grinding the plant tissues of the sample added with the reagent, and the ground sample is conveyed to a sample pouring position through a conveying chain;
s22: a pressing ring cylinder of the filtrate extraction mechanism drives a pressing ring of rubber to press downwards, filter paper is compacted on the table board, a sample cup is poured, and a sample solution is poured into the pressing ring;
s23: part of the residual sample liquid is dripped into the cleaning water receiving tank, the sample cup is rotated to the lower part, the sample cup is supported by a limiting strip, and the sample cup is conveyed to a cleaning and drying position under the driving of a conveying chain to clean and dry the sample cup;
s24: the DCS control system starts a cleaning program firstly, residual liquid flows into a cleaning water receiving tank, then a blower is started to blow the sample cup dry, and finally the cleaned sample cup is conveyed to a sampling position to enter the next cycle under the conveying of a conveying chain;
s25: after the sample solution is poured into the pressing ring, the vacuum pump is opened, the vacuum suction filter tube is used for exhausting air, the filtering efficiency is accelerated, after the filtrate is extracted, the vacuum pump is closed, and the detection filtrate with the volume of at least 50ml is obtained in the filtrate cup;
s26: the pressing ring cylinder rises, the pressing ring is automatically opened, the unwinding roller is driven by the unwinding motor to unwind, the used filter paper and filter residues are automatically wound away by the paper collecting roller driven by the paper collecting motor, and the filter paper and the filter residues are put into the filter paper residue filtering box;
s27: and (4) sending the detection filtrate obtained in the step (S25) to an optical rotation glucose detector for analysis, and automatically recording information big data storage and accounting settlement through a DCS (distributed control system).
