SISTEMA DE PULVERIZAÇÃO POR NEBULIZAÇÃO DA CALDA ATRAVÉS DE FREQUÊNCIA ULTRASSOM EM CONJUNTO COM A INDUÇÃO ELETROSTÁTICA

Abstract

The research in technology of application of agricultural defensives have increased of significant form in Brazil and the whole world. The efforts are seen concentrating in the development and perfectioning of existing techniques already, in this direction the present invention is about a system of spraying for nebulization of syrup through frequency ultrassom in set with the electrostatic, attachable induction the motor tractive vehicle, that uses the technique of nebulization for frequency ultrassom, where the equipment anger to transform present syrup into the tank in a mist through its atomizaton using piezoelétricos transducers that they receive signal from an oscillator settled to a plate of integrated circuit control plate, what fara with that these transducers vibrate a band of frequency of up to 50 MHz, thus making breaks of water particles/product generating ultrafine drops, lesser that 50 micrometers (µm). The advantage to operate with small drops is evidenced by the theoretical density, gotten with one liter of syrup on a plain surface, having as example drops with diameter of 10 micrometers (µm) has an area covered of 1500 mm ² arriving until the 19000 drops for cm ², on the other hand, small drops are more susceptible astray, aiming at to reduce this effect the system in question will also be endowed with an electrostatic inductor, what fara with that this micron drops is electrically loaded, being more good attracted by the plant, increasing the efficiency in the application and diminishing the losses for the environment. This new system has as purpose to minimize the related problems the application of agricultural defensives, however it could also be used in the application of insecticides and fungicides, as well as, climatization and desinfestação of environments and control of agricultural and urban endemic diseases, mainly in the question covering of target and drift.
