JPH06343378A - Injurious bird repulser - Google Patents

Abstract

PURPOSE:To obtain an injurious bird repulser capable of causing an injurious bird to withdraw from paddy field, farmland or an orchard by utilizing a disaster cry (distress call) produced when a sensation of fear is held by the bird. CONSTITUTION:A speaker is attached to the interior of a bird model and connected through an amplifier to a recorder and reproducer. A 'piercing cry' (distress call) which is a disaster cry produced when a bird is caught by a natural enemy or a trap is prerecorded in the recorder and reproducer and then outputted from the speaker.

Description

Detailed Description of the Invention

[0001]

[Field of Industrial Application] The present invention is intended to remove birds that eat agricultural crops such as rice, fruits and vegetables, and in particular harmful birds such as crows, chicks, sparrows and starlings from fields and orchards to prevent damage to them. It is related to the bird repellent device.

[0002]

2. Description of the Related Art As a conventional method for fighting off harmful birds, a method of suspending scarecrows and carcasses of birds has long been known. In recent years, various methods have been attempted, such as a method in which a reflective tape is stretched around a farm product, a colored balloon is installed, or a repulsive sound is emitted by an explosive sound from an air gun.

[0003]

However, in any of the above methods, although the initial effect is obtained, the effect is diminished as the bird learns over time. There is also a method of catching or eliminating them, but depending on the type of bird, there are also those that play a role of exterminating pests, so overfishing or large amount of elimination causes a problem of returning the balance of the ecosystem. . Therefore, the applicant of the present invention has earnestly studied and has completed the present invention. In view of the above-mentioned problems of the conventional method for repelling harmful birds, the present invention uses a distress voice (distress call) that is produced when a bird feels fear to repel harmful birds. The purpose is to provide a device.

[0004]

Therefore, in the present invention, the harmful bird repelling device is provided with a snake model having a driving means, a bird model also having a driving means, and a bird distress voice incorporated in the bird model ( It is composed of a voicing means for generating a distress call) and a power supply for operating each of the means.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of a harmful bird repelling device according to the present invention, FIG.
[Fig. 3] is a layout view showing a state where a model of a crow and a snake are installed in a field.

As shown in FIG. 1, the crow model 1 has its head portion 2a and wing portions 2b movable up and down by a motor 3a, which is a driving device, and is connected to a control circuit A. A speaker 4 is attached inside. The speaker 4 is a recording / playback device 6 via an amplification device 5.
Is connected to the recording / reproducing device 6 so that the sound of the recorded tape reproduced by the recording / reproducing device 6 can be output. Here, the recording tape is an endless tape, and the "distress call" (distress call), which is a distress voice that is produced when a crow is captured by a natural enemy or a trap, is recorded in advance. The bodies of the snake models 7, 8 and 9 are motors 3b and 3c.
And 3d are made to move in a twisting manner and are connected to control circuits A, B and C. In particular, the snake model 7 is arranged to produce a state in which an attack is being made on the crow model 1. And all of the above devices are timer 1
Storage battery 11 and solar cell panel 1 which is a power source through 0
Connected to 2.

Next, the method of use and the action of the harmful bird repelling device in this embodiment will be described. Field 1 as shown in FIG.
Place the crow model 1 and the snake model 7, 8 and 9 in 3.
At dawn, the current generated from the solar cell panel 12 is temporarily stored in the storage battery 11 and supplied to each device. Here, the timer 10 turns on and off at appropriate intervals, and the crow model 1 and the snake model 7, 8 And 9 are moved, and at the same time, the speaker 4 built in the crow model 1 outputs the crow's distressing voice, "a loud scream". In particular, the crow model 1 moves the head 2a and the wings 2b up and down to make a snake model 7
The crow, who perceives this situation, perceives a dangerous state and does not approach the field 13. In addition, the crow, which rarely flew, also moved away after seeing the snake models 8 and 9 arranged at various places in the field 13. In addition, it is desirable that the crow model and the snake model be of a plug-in type so that the connection with the wiring can be inserted so that the field can be freely rearranged. Further, in the above embodiment, the power is supplied from the solar cell panel, but a household power supply may be used.

[0008]

As described above, according to the present invention, the harmful bird repelling device is provided with a snake model having a driving means, a bird model also having a driving means, and a bird distress voice (disease voice) incorporated in the bird model. Since it consisted of a vocalization means for generating stress calls) and a power supply for operating each of the above means, the crow, who stimulated the fear of the bird and saw this situation, approached the fields and orchards by sensing a dangerous state. There is an excellent effect that the crows that flew away and moved away after seeing the snake models placed in various places in the fields and fruit gardens.
