DYNAMIC SYSTEM FOR AUTOMATICALLY ADJUSTING THE ANTI-DROP PRESSURE FOR PRECISE HERBICIDE APPLICATION

摘要

The invention relates to a dynamic system for automatically adjusting the anti-drop pressure for the precise herbicide application, meant for the equipments provided with a weed discriminating and classifying system. The claimed system consists of a tank () for herbicidal compositions, a filter (), a pump (), a pressure adjuster () for adjusting the pressure, a pressure adjuster () for fine adjustment of pressure, a central unit () with technical and functional characteristics which allow the use thereof on a vehicle, a speed sensor (), a pressure sensor (), a pressure gauge (), a controller () for actuating some spraying elements () mounted on a weed control boom (), a controller () for actuating some electric valves (), some connection elements such as electric cables (), hoses (), the spraying elements () being formed of a cast body () in which there are mounted a nozzle (), an element () for dispersing the spraying jet, a spring (), a ball (), an element () for dynamically adjusting the anti-drop pressure and a motor () coupled by means of a pin () to a piston which has a stroke () to adjust the pressure for opening or closing the nozzle () depending on the signal received from the speed sensor (), as processed by the central unit () and transmitted by means of the controller (), while in one embodiment the spraying element () can be replaced with the spraying element (), consisting of the same elements () mounted in a body (), a nozzle (), a piston () which moves inside the nozzle () with a stroke () for adjusting the pressure for opening or closing the nozzle () under the influence of the magnetic field produced by some coils () mounted in a housing () and driven by means of the driver () controlled by a controller () depending on the signal received from the speed sensor () and processed by the central unit ().
