A kind of chemical fertilizer automatic mixing machine based on Zigbee-technology
Technical field
The present invention relates to a kind of chemical fertilizer automatic mixing machine based on Zigbee-technology.
Background technology
Chemical fertilizer refers to chemically manufacture or exploitated ore, through the fertilizer being processed into, also referred to as inorganic fertilizer
Material, including nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, micro-fertilizer, compound fertilizer etc., they have following common features: composition is simple, support
Divide content high;Fertilizer efficiency is fast, and fertile strength is violent;Some fertilizer has acid-base reaction;General without organic matter, without the effect of Soil building.Change
Fertilizer type is more, and character and application process differ greatly.
Grand nutrition element nitrogen in soil, phosphorus, potassium are generally not capable of meeting the demand of plant growth, need to use nitrogenous,
Phosphorus, the chemical fertilizer of potassium are supplied.And outside dechlorinating in micronutrient element in soil and not lacking, the most several nutrients then need to use
Trace-element fertilizer.Chemical fertilizer is typically mostly is inorganic compound, and only carbamide [CO (NH2) 2] is organic compound.All can containing only one
Indicate that the chemical fertilizer of the nutrient of content is referred to as straight fertilizer, such as nitrogenous fertilizer, phosphate fertilizer, potash fertilizer etc..All containing nitrogen, phosphorus, three kinds of potassium battalion
Support in element two or more and can indicate that the chemical fertilizer of its content is referred to as compound fertilizer or mixed fertilizer.Grade is chemical fertilizer
The leading indicator of quality.It refers to effective nutrient or the percent content of its oxide in chemical fertilizer products.
Chemical fertilizer needs to carry out mixing to increase efficiency before administration, and existing chemical fertilizer automatic mixing machine concentrates on mixed
Close function and ignore the function of discharging, be primarily present following shortcoming: (1) is configured with converter, time in the rotating shaft of storage vat
Function is set etc., and sub-material upon mixing, a common butterfly valve is only installed, there is blowing clean, have the problems such as residual;
(2) the most single gyration of storage vat, can only rely on the material position that the whole circle revolution of storage vat is piled up in changing hopper, shadow
Seriality and the work efficiency of sub-material work are rung.(3) in current chemical fertilizer mixing machine system design, although all emphasize to mix
Even, the most generally ignore the accurate monitoring and metering of various chemical fertilizer amount.
