Device for increasing or modifying air volume along tangential direction, has ventilator placed vertically to modify and increase efficiency of sprayer, where ventilator tangentially positions air volume at faded crops

摘要

The device has a ventilator (7) placed vertically to modify and increase efficiency of a sprayer. The ventilator tangentially positions an air volume (5) at faded crops. The ventilator placed vertically naturally functions by the air volume created by a helical or centrifugal propeller (3) of the sprayer. A mechanical drive (1) is pulled by a machine (2) e.g. farm tractor, thermal engine and electric motor.
