Description
Technical field
This utility model belongs to electronics and agricultural technology field, is reminded with regard to a kind of grain drill kind grain obstruction acousto-optic
Device.
Background technology
Common crop seeding method has：Broadcast sowing, drilling, bunch planting and precise sowing etc..So-called drilling：Be by seed by
Line-spacing, depth of planting according to crops requirement, application rate are broadcast into strips.Because drilling is conducive to crops logical in growth period
Wind, printing opacity, the task management such as are easy to field fertilization, hoe up weeds, so drilling technology is widely used in the farmings such as Semen Tritici aestivi, Semen Maydiss, beans
The sowing of thing.
Regular drill planter at seeding time, due to being contaminated with the debris such as careless bar, other seeds or stone in seed, it is easy to make
Block in pipeline in kind of grain dropping process.Because the kind grain for broadcasting is intended to cover soil, once occurring during sowing
Grain obstruction is planted, operator are difficult to find kind of a grain broadcast leakage phenomenon in time that where broadcast leakage has no way of finding out about it, it is also difficult to search, if too late
Shi Jinhang is remedied, it will cause crops to be short of seedling disconnected ridge, affects crop yield and harvest.
It, in order to ensure seeding quality, is vast that grain drill kind grain obstruction acousto-optic reminiscences described in the utility model are
A kind of grain drill kind grain obstruction acousto-optic reminiscences of peasant household's design.There are this acousto-optic reminiscences to monitor that kind of a grain exists the moment
Whereabouts situation in pipeline.Once planting grain to block in the pipeline for falling, acousto-optic reminiscences can in time remind operator
Member take corresponding measure, prevented plant grain large area broadcast leakage phenomenon generation, be effectively improved crops seeding quality and
Work efficiency.
Grain drill kind grain described in the utility model described further below blocks acousto-optic reminiscences in implementation process
Involved necessary, guardian technique content.
Utility model content
Goal of the invention and beneficial effect：This utility model is to ensure the seeding quality of crop, designing for wide farmers
A kind of grain drill kind grain obstruction acousto-optic reminiscences.This acousto-optic reminiscences can monitor kind of grain whereabouts in the duct the moment
Situation；Once plant during grain falls in pipeline blocking, acousto-optic reminiscences can in time remind operator to take accordingly
Dredging measure, so as to the phenomenon for having prevented large area broadcast leakage occurs, is effectively improved the seeding quality and field work of crop
Efficiency.
Circuit operation principle：The signaling conversion circuit of grain drill kind grain obstruction acousto-optic reminiscences is connected into without steady state function
Trigger, model CD4011 that the NAND gate circuit IC1 of two input four is used, the NAND gate circuit IC1's of two input four
14th foot meets circuit anode VCC；7th foot of the NAND gate circuit IC1 of two input four meets circuit ground GND；
Using infrared ray photoelectric coupling principle the situation that kind of grain falls in the duct is converted into the signal of telecommunication to control acousto-optic
Alert circuit.Infrarede emitting diode D1 and infrared type phototriode VT1 is aspectant installed in kind of grain falling duct
Middle part, makes the infrared light that infraluminescence diode D1 sends just be radiated on infrared type phototriode VT1.When kind of grain is in pipe
In road during normal whereabouts, the kind grain that infrared light is just fallen discontinuously is blocked, and is made on the colelctor electrode of infrared type phototriode VT1
Produce interruption negative pulse, negative pulse is coupled to the positive pole of electrochemical capacitor C2 by electrochemical capacitor Cl, prevent electrochemical capacitor C2 from by
Charge, the voltage close zero on electrochemical capacitor C2 positive poles so that the 1st foot of the NAND gate circuit IC1 of two input four is low level,
4th foot of the NAND gate circuit IC1 of two input four is changed into high level, be sent to the NAND gate circuit IC1 of two input four the 5th foot and

So all the time it is a low level on the colelctor electrode of infrared type phototriode VT1, because it is a direct current signal, it can not
Reached on the positive pole of electrochemical capacitor C2 by electrochemical capacitor Cl, then electrochemical capacitor C2 is just started to charge up, electrochemical capacitor C2 positive poles
On voltage gradually rise, the 1st foot for making the NAND gate circuit IC1 of two input four is changed into high level, the NAND gate of two input four
4th foot of IC circuit 1 is changed into low level, be sent to the 5th foot of the NAND gate circuit IC1 of two input four and the 6th foot it is anti-phase after, make two
The 3rd foot output high level of the NAND gate circuit IC1 of input four, the high level directly leads enhancement mode N-channel field effect transistor VT2
It is logical, cause acoustic-optic reminding circuit to obtain electric work；
The foot of outfan the 3rd of the NAND gate collector IC1 of two input four is changed into high level can be maintained 6~8 seconds, and adjustment is without steady
The capacity of the electrochemical capacitor C3 in state flip-flop circuit can change level output width, i.e.,：Control the NAND gate of two input four
3rd foot output high level time delay of IC circuit 1.
