Using ultrasonic sensors on field sprayer

Prskanje kod velikih radnih širina zamoran je posao za vozača koji bez upotrebe autopilota ili voznih staza teško ravnomjerno nanosi sredstva za zaštitu bilja. U posljednjih nekoliko godina na suvremenim poljoprivrednim prskalicama velikih radnih širina koriste se ultrazvučni senzori kako bi se osigurala optimalna visina armature kod većih brzina rada na nagnutim terenima kada se na usjeve nanose tekuća gnojiva i pesticidi. Ultrazvučni senzori pomoću mikroprocesora i hidrauličkih ventila automatski podešavaju visinu mlaznica na odgovarajući razmak od zemlje odnosno usjeva, što značajno smanjuje gubitke u zrak i tlo te istovremeno zbog ravnomjerne raspodjele zaštitnih sredstva povećava njihovu biološku učinkovitost.Spraying at large working width is a tedious job for the driver. It is very difficult to distribute apply plant protection products uniformly without using the autopilot or driving paths on the field. In recent years the modern agricultural sprayers with large working width can be equipped with ultrasonic sensors to ensure optimal height reinforcement of the boom also at higher speed during the operation on slopes, so liquid fertilizers and pesticides are applied evenly in the crops. Ultrasonic sensors together with a microprocessor and solenoid hydraulic valve automatically adjusts the height of the nozzle at an appropriate distance from the soil or crops which significantly reduces losses of pesticides in the air and soil, and at the same time due to even distribution of protective agents increases their biological effectiveness
