Description
One, affiliated technical field
The utility model relates to a kind of grain quality grade pick-up unit, judges in particular for the detection and the quality grade of cereal such as corn, wheat turnover port, accumulating, purchase, commodity inspection and machining sector's moisture, unit weight.
Two, background technology
It is basis with matter price, discount button amount and advance price increment that cereal waits check surely, is directly connected to trade both sides' economic interests.Among State Standard of the People's Republic of China-corn GB1353-1999 pure kernel yield waited surely that to change unit weight into fixed etc.Moisture content index is unified for being no more than 14.0%, and increase unsound grain index is decided to be and is no more than 5.0%.Can adopt the instrument testing except that part index numbers such as moisture, unit weights at present, all the other indexs such as unsound grain, impurity etc. adopt organoleptic examination.
Grain moisture detects resistance and the 2 kinds of methods of electric capacity that generally adopt at present, electric-resistivity method is better to the detection adaptability of the moisture of small particles materials such as paddy, wheat, no matter grain size adaptability is better and capacitance method is to various cereal, and the measurement of moisture must be carried out temperature compensation.Resistance and capacitance method can satisfy requirement of actual application in the measurement in main moisture measurement district, and be bigger in the error in high-moisture district.
Cereal unit weight detects and generally adopts pneumatic hammer formula liter weighing tester.Be applicable to that as HGT-1000 type liter weighing tester the detection of granule grain waits (as the wheat class) surely, the HGT-1000A liter weighing tester is applicable to that the detection of grains waits surely that (as diameter is that the cereal tube in the sluice gate aperture of 40mm can detect the fixed etc. of beans, corn class grain.With diameter is that the cereal tube in 30mm sluice gate aperture can detect the fixed etc. of wheat class grain).Common employed moisture meter and liter weighing tester are two independently instruments, and cost is than higher; Running program is loaded down with trivial details; Inefficiency; Measuring accuracy is lower; Poor repeatability; Error ratio is bigger.
The quality grade of cereal all on the basis of moisture, unit weight analytical measurement, is judged according to standard GB 1353, GB1351 by operating personnel.There are shortcomings such as measuring error is big, trivial operations at present.
Three, utility model content
The purpose of this utility model addresses the deficiencies of the prior art, and a kind of simple in structure, reliable operation, time saving and energy saving, the grain moisture that cost is low, precision is high, the device that unit weight is measured and quality grade is judged are provided; The detection and the quality grade that are applicable to cereal turnover port, accumulating, purchase, commodity inspection and machining sector's moisture such as corn, wheat, unit weight are judged, comprise water content detection unit, weighing unit, volumetric metering unit, material storage element, vibrating transportation unit, data processing unit etc.It is characterized in that adopting the micro-vibration conveying device that material to be measured is evenly sent into the volumetric metering unit, the quality grade of determining cereal according to the actual measurement unit weight that enters volumetric metering unit cereal and moisture.During work, the hopper of at first material to be measured being packed into, the moisture and the temperature of the interdigital capacitor pole plate sensing material by hopper rear wall inboard, measurement result by bus transfer to the computer data processing unit; Then, little vibrator works makes hopper produce resonance, and the material in the hopper evenly falls into the capacity cup from hopper and receiver, after treating that material is filled the capacity cup, stop feeding, plate is inserted in the slot of receiver bottom, gently unnecessary material in receiver, plate and the dish is taken away then; After treating that electronic scales is steadily, read the quality and the unit weight of tested material from the electronic scale nixie display, simultaneously with the measurement result of quality by bus transfer to the computer data processing unit; At last, the computer data processing unit on the basis of information such as moisture, temperature, unit weight, determines the grade of cereal according to standard GB 1353, GB1351.
