Description
Technical field
The invention belongs to electronic technology and agricultural production, be to fall to blocking HONGGUANG alarm about a kind of seeder seed
Device.
Background technology
Common crop seeding method has: broadcast sowing, drilling, bunch planting and precise sowing etc..So-called drilling: be by seed by
The line-spacing of as requested, depth of planting, application rate are broadcast into strips.Because drilling is conducive to crops to ventilate during growing, printing opacity,
It is easy to field fertilization, the task management such as hoe up weeds, so drilling technology is widely used in the sowing of the crops such as Semen Tritici aestivi, Semen Maydis, beans.
Regular drill planter at seeding time, due to be contaminated with in seed grass bar, other foreign material such as seed or stone, it is easy to make
Become in kind of grain dropping process and block in pipeline.Kind grain because broadcasting is intended to cover earth, kind of a grain blocking once occurs, broadcasts
The personnel of kind are difficult to find in time broadcast leakage phenomenon, and where broadcast leakage has no way of finding out about it, it is also difficult to search, if inconvenience is remedied in time, it will lead
Cause crop to be short of seedling disconnected ridge, affect crop yield and harvest.
Blocking HONGGUANG alarm device in seeder seed of the present invention whereabouts is to ensure that seeding quality, for vast agriculture
A kind of seeder seed for crop drilling of family design falls to blocking HONGGUANG alarm device.There is this HONGGUANG alarm device
Kind of grain whereabouts situation in the duct can be monitored constantly.Once plant grain to block in the pipeline fallen, HONGGUANG alarm device
Operator can be reminded in time to take corresponding measure, stop to plant the generation of grain large area broadcast leakage phenomenon, be effectively improved
The seeding quality of crops and work efficiency.
Seeder seed of the present invention described further below falls to blocking HONGGUANG alarm device institute in implementation process
Relate to necessity, guardian technique content.
Summary of the invention
Goal of the invention and beneficial effect: the present invention is to ensure that the seeding quality of crop, designed for wide farmers
Plant the seeder seed for crops drilling to fall to blocking HONGGUANG alarm device.This HONGGUANG alarm device can monitor kind constantly
Grain whereabouts situation in the duct；Once planting during grain falls in pipeline and block, HONGGUANG alarm device can be reminded in time
Operator take to dredge accordingly measure, thus the phenomenon having stopped large area broadcast leakage occurs, and is effectively improved crop
Seeding quality and field work efficiency.
Circuit operation principle: seeder seed falls blocking HONGGUANG alarm device employing Infra red photo electric principle by corn
Plant grain dropping process in the duct is changed by infrared signal and control HONGGUANG warning circuit.By infrarede emitting diode D1 and
Infrared type light sensitive diode D2 faces and is arranged in kind of grain falling duct, just makes the infrared light that infraluminescence diode D1 sends
It is radiated at well on infrared type light sensitive diode D2.When kind of a grain normally falls in pipeline, the screening that infrared light is just broken by kind of intergranular
Gear, makes to produce on the positive pole of infrared type light sensitive diode D2 continuous print negative pulse, and is coupled to electrolysis electricity by electrochemical capacitor Cl
Holding the positive pole of C2, make electrochemical capacitor C2 not charge, the voltage on electrochemical capacitor C2 positive pole is close to zero, thus time base circuit IC1
The 2nd foot be low level；Simultaneously because the effect of PNP transistor VT1, as long as the voltage on electrochemical capacitor C2 is zero, then,
Electrochemical capacitor C3 also will not be electrically charged, and the 2nd foot of such time base circuit IC1 and the 6th foot are low level, time base circuit IC1's
3rd foot output high level, makes HONGGUANG warning circuit can not work without electricity, the situation that this explanation corn kind grain falls in the duct
Normally.
When kind of grain is the most blocked, plants grain and no longer normally fall from pipeline, so that infraluminescence diode
The infrared ray that D1 sends is radiated on infrared type light sensitive diode D2 all the time, makes the resistance of infrared type light sensitive diode D2 become rapidly
Little, the positive pole of such infrared type light sensitive diode D2 is a low level all the time, and because low level is a direct current signal, it can not
Being coupled on the positive pole of electrochemical capacitor C2 by electrochemical capacitor Cl, then electrochemical capacitor C2 just starts to charge up, then electrochemical capacitor
C3 charges also with the charging of electrochemical capacitor C2, base electricity when quickly the voltage on electrochemical capacitor C2, electrochemical capacitor C3 just reaches
The turnover voltage of road IC1, the 2nd foot of time base circuit IC1 and the 6th foot become high level, make time base circuit IC1 reset, Shi Ji electricity
The 3rd foot output low level of road IC1, so that red light emitting diodes LED1～LED6 is because obtaining electric being lit, this illustrates pipeline
Two-story valley species seed there occurs blocking in dropping process.
