Description

Vibration cereal weight

One, affiliated technical field

The utility model relates to a kind of vibration cereal weight, in particular for the detection of cereal such as corn, wheat, paddy rice turnover port, accumulating, purchase, commodity inspection and machining sector's 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.

At present, 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, HGT-1000A type liter weighing tester is applicable to that the detection of bulky grain grain 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 the cereal tube in 30mm sluice gate aperture).Common employed moisture meter and liter weighing tester are two independently instruments, cost than higher, running program is loaded down with trivial details, inefficiency, measuring accuracy are lower, poor repeatability, error ratio are bigger.

Unit weight is the quality of grain seed in unit volume, represents with grams per liter (g/L).Grain unit weight is the overall target of quality such as reflection grain seed size, shape, regularity, uniformity coefficient, quality, the ventral groove depth, endosperm quality.In the grain standard of many developed countries, all unit weight is classified as an important indicator in the world.China's grain department is also with the important parameter of unit weight as the evaluation grain quality.Therefore, research cereal unit weight detection method and pick-up unit thereof all have important and practical meanings for cereal sowing, processing, storage, transportation and drying process design etc.

In conjunction with our discovering, there are following problem in the detection principle and the process of the existing liter weighing tester of analysis-by-synthesis at present:

1. when the low present most of products of accuracy of detection detect the unit weight of cereal, sieve back sample is when pouring the cereal tube into, because there is the existence of impurity the inside, the automatic classification of sample full entry, big and heavy cereal and the heavy impurity that is not sifted out fall into earlier in the tube, fall in the tube behind small and light cereal and the impurity, when plate inserts, small and light cereal and impurity have all been inserted, and the result causes error bigger; The actual measurement result of also finding existing cereal liter weighing tester to unit weight increase with the number of times of measuring, so the measurement result of the actual unit weight of national Specification is got the mean value of adjacent 2 measurements.

2. it is loaded down with trivial details to manipulate inconvenient present product operation program, and inefficiency uses inconvenience, and because misoperation causes very big error easily.

3. the narrow every kind of instrument of accommodation can only detect a kind of unit weight of cereal, is not suitable for for detecting other kind, and the adaptability that product detects is relatively poor.

4. the result shows the counting of product unit weight weighing accepted scale at present not directly perceived, the reading inconvenience, and be easy to generate error.

Three, utility model content

The purpose of this utility model provides a kind of simple in structure, reliable operation, vibration cereal weight time saving and energy saving, with low cost, that measuring accuracy is high, to overcome the shortcoming that at present existing unit weight pick-up unit exists.

The utility model provides a kind of instrument that is applicable to that cereal unit weight detects, comprise electronic weighing unit, volumetric metering unit, compositions such as vibration feeding unit, material storage element and shell, it is characterized in that adopting mini vibrator to carry material to be measured evenly to enter the volumetric metering unit, enter the tight ness rating uniformity of cereal in the capacity cup with assurance, thereby improve the correctness of unit weight metering.

The beneficial effects of the utility model:

1, the utility model has adopted the vibration feeding style, makes the cereal tightness degree uniformity that enters the volumometer measuring cup, has improved accuracy, objectivity, fairness and the comparability measured.

2, adaptability of the present utility model is good, and at different grain varieties, but a tractor serves several purposes can be measured the unit weight of various types of grain products such as corn, wheat.

3, adopted touch-key, the digital demonstration, convenient for users.

4, realized the digitizing that cereal unit weight detects, and shortcomings such as because use capacity cup carries out volumetric metering, the detection error that has overcome existing bulk density tester is big, poor repeatability, accuracy of detection height, good stability, easy to operate, low cost and other advantages had.

The present invention is particularly suitable for the mensuration of cereal turnover port, accumulating, purchase, commodity inspection and machining sector's cereal unit weight.As be used for grain purchases and wait device etc. surely.
