DEVICE FOR SCARING BIRDS USING SOUND VIBRATIONS Russian patent published in 2015 - IPC A01M29/18 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of scaring birds. The device for scaring birds affects the area of space with ultrasonic and close to ultrasonic vibrations. The device comprises a housing with several surfaces of radiation. In the surfaces, the cylindrical recesses are formed as resonating spaces. Through the housing with a cylindrical inner space the axis passes. The fixed, non-rotating axis is divided into two parts. The first part is formed by the outer support flange and the inner support flange with the stay bolts screwed between them. Between the both support flanges the electric motor and reduction gear is located. The second part of the non-rotating axis is formed by the pot-shaped sleeve. On the sleeve the contact ring is fixed. The contact ring is adjacent slidably to the current collector. The current collector is connected to the rotating housing. From the current collector the wires pass through the hole to the resonator space.

EFFECT: effective impact on the areas to be protected is provides.
