Weighing sensor I, metering screw is connected to weighing sensor II；The batching method of material measuring device is as follows：
A) material measuring device is started, be added to the material in feed bin in scale hooper by feeding spiral, in making scale hooper
Material reaches upper limit gravimetric value, and upper limit gravimetric value is the 50%-90% of the range of scale hooper；
B) start charging gear and metering screw realizes dispensing, during original state, in the scale hooper of the measurement of weighing sensor I
Weight of material be W0, charging gear start t second after weighing sensor I measurement scale hooper in weight of material be Wt, by public affairs
Formula Qn=W0-WtCalculate the cumulative weight Q of the material that run time is conveyed from charging gear after t seconds to metering screwn；
C) the metering screw weight signal of the collection of weighing sensor II is A, and calculating metering screw by formula F=A × P works as
The flow F of preceding outputting material, wherein P are the flow calibration coefficient of weighing sensor II；
D) formula is passed throughCalculate the summation Q that metering screw conveys material after running t secondsm；
E) when the material in scale hooper is less than or equal to lower position, by formulaCalculate weighing and sensing
The correction value of the flow calibration coefficient of device II, lower position is the 10%-50% of the range of scale hooper；
F) by the correction value P' of flow calibration coefficient to step c) in former flow calibration FACTOR P be modified, according to public affairs
Formula F'=A × P' calculates the flow F' of the revised current outputting material of metering screw, feeding spiral by the material in feed bin with
Flow is equal to the speed of F' and is delivered in scale hooper until the material in scale hooper reaches upper limit gravimetric value；
G) repeat step step b) to step f).
Above-mentioned charging gear uses screw(-type) feeder.
Above-mentioned charging gear uses revolving plow reclaimer.
The beneficial effects of the invention are as follows：Computation flow and the difference of setting flow, lead to during whole measure control
The speed of control metering screw is crossed, reaching actual material is carried out the purpose of dispensing by setting flow, improves measuring accuracy, is not had
Dead area in measure process, demarcates easy, and long-time stability are good.
