Abstract
The utility model relates to a vibration-preventing device for a tree seedling; a vibration sensor RPD (resistance pressure detector) is used as a vibration-collecting signal source; one end of the vibration sensor RPD is input into an input end of an operational amplifier IC (integrated circuit ) 1 by a resistance R2; the other end of the vibration sensor RPD is connected in parallel with a resistance R1 and a capacitor C1, then is connected in series with a capacitor C2 and a resistance R3 and finally is input into the other input end of the operational amplifier IC1; an output signal of the operational amplifier IC1 is rectified by a diode D1, then is input into an input end of a comparator IC2, and finally is input into the other input end of the comparator IC2 by resistances 6 and 7 to form a reference voltage; the reference voltage is connected with a triode Q1 by an output end of the comparator IC2, is output by a collector electrode of the triode Q1 and is connected with a voice alarm chip IC3; the voice alarm chip IC3 is coupled to an LM386 voice frequency amplifying chip IC4 by a capacitor C4; the reference voltage is connected with a loudspeaker Y by an output end of the LM386 voice frequency amplifying chip IC4; the reference voltage is judged to be in excess of force bearing range so as to give out voice alarm signals which remind people and achieves the purpose of warm reminder, thereby effectively raising the survival rate of seedlings.
Description
Technical field
The utility model relates to a kind of sapling antihunting device.
Background technology
Sapling is the required plant of afforestation project, is loaded in highway both sides or park the inside.Often be subjected to artificial careless destruction.Some little saplings are just planted when going down, and can not shake energetically, otherwise just descend for the viablity of sapling greatly.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of sapling antihunting device is provided.
The technical scheme that the utility model adopted is such: a kind of sapling antihunting device, by vibration transducer RPD as the vibration acquisition signal source, the end of vibration transducer RPD is input to the input end of operational amplifier IC1 through resistance R 2, other end parallel resistance R1, after the capacitor C 1, series capacitance C2 again, resistance R 3 is input to another input end of operational amplifier IC1, the output signal of operational amplifier IC1 is input to the input end of comparer IC2 after diode D1 rectification, by resistance R 6, another input end that the output terminal of R7 is input to comparer IC2 constitutes reference voltage, output terminal by comparer IC2 connects triode Q1, collector output by triode Q1 connects audio alert chip IC 3, audio alert chip IC 3 is coupled to LM386 audio frequency power amplifier chip IC 4 through capacitor C 4, by the output terminal connection loudspeaker Y of LM386 audio frequency power amplifier chip IC 4.
Described vibration transducer RPD is made up of piezoelectric patches and spring hammer, is installed on the sapling.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: this device adopts vibration transducer after signal relatively amplifies, and through judging that surpassing field of load sends the audio alert signal, reminds people is noted, reach the effect of warm tip, improve the viablity of sapling effectively.
Description of drawings
