At present, the grade unit weight defining corn and wheat in national food quality standard is determined, its objective is the inherent quality of reaction corn and wheat, its essence measures its density exactly, unit weight is the quality of grain seed in unit volume, represents with grams per liter (g/L).Material volume weight is the overall target of the quality such as reflection grain seed size, shape, regularity, uniformity coefficient, quality, the ventral groove depth, Germplasms quality.In the grain standard of many developed countries in the world, all unit weight is classified as an important indicator.China's grain department is also using the important parameter of unit weight as evaluation grain quality.
In prior art, the material volume weight such as cereal detects and generally adopts random detection mode, namely a certain amount of random sampling observation is carried out to all cereal to be detected, and the mode of sampling observation is all adopt manual operation, using appliance extracts a certain amount of cereal, then carries out unit weight detection to the cereal of this extraction.Existing detection mode efficiency is low, cannot detect in a large number cereal, can not carry out quality monitoring accurately to a large amount of cereal, cannot meet materiel machining enterprise for the needs produced.
Summary of the invention
For the defect existed in prior art equipment, the present invention proposes a kind of method for automatic measurement of material volume weight, can realize the automatic measurement of material volume weight, improves and measures efficiency, reduces production cost, meets the demand that materiel machining enterprise produces.
For achieving the above object, the present invention proposes a kind of method for automatic measurement of material volume weight, comprises the following steps:
1) grain delivers into buffering feeder hopper one by pipeline and hoister, and valve one is opened, and valve two and valve three are all closed;
2) level-sensing device one detects grain position signalling, and by this Signal transmissions to valve one, make valve one closedown, valve two is opened;
3) after 10 to 15 seconds time stablized by grain in scale hooper, scale hooper starts to weigh, and after weighing, data are carried out preserving and carried out calculating unit weight;
4) valve three is opened, and grain enters and arrives first in buffering hopper two, then by hoister and Pipeline transport in grain storage silo;
5), after level-sensing device two can't detect grain position signalling, will transmit the signal making it close to valve three, valve three is closed;
6) weighing data resets, and valve two is closed;
7), after the detection that grain is in the end a pipeful of, volume-weighted average is calculated.
Before grain enters buffering hopper one, first through moisture teller, when grain weight is more than or equal to 100KG, moisture teller starts the water percentage measuring grain.
Described scale hooper outer wall place coupling arranges weighing sensor, valve one, valve two, valve three, level-sensing device one, level-sensing device two and weighing sensor are all connected with instrument control box, instrument control box is used for by-pass valve control switch and gathers level-sensing device signal, and instrument control box is connected with backstage computer; Weighing sensor and moisture teller are used for the information transmission after by detection to backstage computer, and backstage computer stores after the information processing received again, and weighing sensor is the sensor that three couplings are arranged on outside scale hooper.
Beneficial effect
The present invention passes through
By controlling the cooperation of level-sensing device and operated pneumatic valve in whole process, making weighing sensor realize carrying out continuous detecting to the weight of all grain, and detection data are carried out the unit weight information processing rear storage grain; Improve measurement efficiency, guarantee all can accurately detect all grain, and reduce production cost, can meet comprise cereal material production enterprise for the quality testing of stored grain.

Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The present invention proposes a kind of method for automatic measurement of material volume weight, comprises the following steps:
1) grain delivers into buffering feeder hopper one by pipeline and hoister, and valve one is opened, and valve two and valve three are all closed;
2) level-sensing device one detects grain position signalling, and by this Signal transmissions to valve one, make valve one closedown, valve two is opened;
3) after 10 to 15 seconds time stablized by grain in scale hooper, scale hooper starts to weigh, and after weighing, data are carried out preserving and carried out calculating unit weight;
4) valve three is opened, and grain enters and arrives first in buffering hopper two, then by hoister and Pipeline transport in grain storage silo;
5), after level-sensing device two can't detect grain position signalling, will transmit the signal making it close to valve three, valve three is closed;
