Abstract

The invention discloses an alarm for expelling and scaring birds and preventing the birds from stealing fruits on fruit trees to eat. The alarm comprises a machine case, fixing bands and an alarming circuit. The alarming circuit comprises a power supply, a switch, a timer and an electronic sound device, wherein the switch is installed on a shell of the machine case, the timer and the power supply are installed in the machine case, the electronic sound device is installed on the shell of the machine case, and the two fixing bands are fixed to the shell of the machine case and can be elastic bands or adhesive bands or tying bands or buckled bands; the power supply supplies required electric energy to the alarming circuit, the switch controls the whole alarming circuit to open and close, the timer sends drive signals to the electronic sound device at intervals, and the electronic sound device receives the drive signals sent by the timer and then works and makes a loud sound.

Description

A kind ofly prevent that birds from stealing carpophagous alarm

Technical field

The present invention relates to a kind of alarm, more particularly, relate to a kind ofly prevent that birds from stealing carpophagous alarm.

Background technology

In the time of fruit maturation on fruit tree, tend to attract large quantities of birds and eat steathily, bring economic loss to like this owner of fruit tree.If this situation occurs in the orchard of large quantities of fruit trees, will cause the larger loss of fruit tree owner and injury.If orchard owner engages employee to drive birds, orchard is large first, needs headcount many, and expense is high, after second birds are driven away, can fly back again at once, and artificial like this effect of driveing is had a greatly reduced quality.And if with broadcasting sound equipment, drive birds, play for a long time not only that power consumption is large, and the sound that sends of continuous audio amplifier, after birds adapt to, just can not feel scaring, dispersion effect weakens.If the sound equipment sending of sound equipment is interrupted, send at set intervals the sound, so conscientiously steal food or prepare to steal the birds of food will be suddenly frightened and fly away, stop eating steathily fruit, not only saving power supply but also dispersion effect can increase greatly.So, on market, needing a kind of energy saving, dispersion effect is good, prevents that birds from stealing carpophagous alarm.

Summary of the invention

The object of the invention is: provide a kind of and drive, frighten birds, prevent that on fruit tree, fruit is stolen the alarm of food by birds.

Of the present inventionly a kind ofly prevent that birds from stealing carpophagous alarm, comprise cabinet, fixed band, warning circuit, described warning circuit comprises power supply, switch, timer, electronic audio, described switch is placed on the shell of cabinet, described timer and power supply are placed in cabinet, described electronic audio is placed on the shell of cabinet, on described casing, be fixed wtih two fixed bands, described fixed band can be elastic cord, adhesive tape, frenulum or cingulum, described power supply provides required electric energy for warning circuit, described switch is controlled the opening and closing of whole warning circuit, described timer sends and drives signal to electronic audio at set intervals, described electronic audio receives timer after the driving signal of its transmission, will work, send the sound of louder volume.

Electronic audio of the present invention can interrupter duty, so both reached energy saving, there is again the good object of driveing birds, effectively prevent that birds from eating fruit steathily, and owing to being fixed wtih two fixed bands on shell of the present invention, so can be easily that device is fixing in the tree, can reach the effect of better driveing birds like this.
