Abstract

At present, the chicken hatch electronic automatic reminding device is not designed and installed in many known large poultry (chicken, ducks and geese) hatching devices, and chicken must be taken out in time once hatching, otherwise, the health of the chicken can be influenced and even the survival of the chicken can be influenced. In order to take out the hatched chicken in time and relieve the labour intensity frequent check of workers, when the poultry brooding hatch electronic reminding device finds chicken-hatching tweets in a hatching box, a microphone MIC converts the tweet of the chicken into an audio signal, and after two-stage amplification is carried out on the audio signal, an alternating current buzzer and a red filament lamp simultaneously work by a driving circuit to remind the workers of taking away the hatched chicken in time. The installation and the use of the poultry brooding hatch electronic reminding device are beneficial to improving the poultry hatch survival rate.

Description

Poultry brooding hatch electronic reminding device

Technical field

The utility model belongs to electronic technology field, relates to a kind of poultry brooding hatch electronic reminding device.

Background technology

At present, known large-scale poultry (chicken, duck, goose) incubation equipment wherein has a lot of not designs, installation chick to hatch the automatic alarm set of electronics, when chick hatches to 21 days left and right sides, though chick can be concentrated relatively and be hatched shell, in case going out shell, chick must in time take out, otherwise can influence the health of chick, even can influence the survival of chick.But, chick hatching always has a spot of or has slightly in advance or postpone out shell a little, and normal work period is also found than being easier to by day, if this situation occurs in night, influence the timely taking-up of hatch chick, two can increase the labour intensity that the night attendant frequently checks for a moment.In order to solve and to improve this situation, be necessary to develop the automatic alarm set of a kind of poultry brooding hatch electronic.

The utility model content

Goal of the invention and beneficial effect: poultry brooding hatch electronic reminding device can in time find have chick to hatch in the incubator, can send sound and light signal immediately in case chick goes out the shell alarm set, reminds the staff in time the chick that hatches to be taken away.

Technical scheme: when chick hatched, microphone MIC was converted to sound signal with the tweeting sound of chick, and sound signal works AC buzzer and red incandescent lamp by driving circuit after amplifying simultaneously.

Main circuit: poultry brooding hatch electronic reminding device is made up of power circuit, audio amplifier circuit harmony light drive circuit.Power circuit is made up of current-limiting resistance R1, commutation diode D1, voltage stabilizing diode D2 and filter capacitor C1.Audio amplifier circuit is made up of microphone MIC, transistor BG1, BG2, resistance R 2～R7 and capacitor C 2, C3.The acousto-optic driving circuit is made up of bidirectional thyristor TR, light emitting diode D3, hummer HA and pilot lamp HL.

Principle of work:

Civil power 220V alternating current is after resistance R 1 step-down current limliting, silicon diode D1 rectification, voltage stabilizing diode D2 voltage stabilizing and electrochemical capacitor C1 filtering, for audio amplifier circuit provides stable 12V working power.When no chick hatched in incubator, MIC picked up the voice signal less than chick, transistor BG2 and not conducting of bidirectional thyristor TR, and HA is sounding not, and D3 and HL are all not luminous.When chick hatched, MIC was converted to sound signal with the tweeting sound of chick, and sound signal is after BG1 amplifies, make transistor BG2 conducting, light emitting diode D3 is lighted, and TR is triggered and conducting, HA gets and sounds a buzzer after electric, and red incandescent lamp HL is also lighted simultaneously.
