METHOD AND DEVICE FOR FLOW RATE REGULATION IN A HYDRAULIC PHYTOSANITARY PRODUCT SPRAYING DEVICE

摘要

The invention relates to a method and a device for flow rate regulation in a hydraulic phytosanitary product spraying device, which is used to maintain a constant volume applied by surface unit both in straight trajectories and in trajectories resulting from the turns of the machine by means of a pulsating spraying system. The flow rate in each nozzle (16) is adapted depending on its effective speed. The device also comprises two differential speed sensors (17), a central electronic unit (20) with a microprocessor, a control panel and actuators (15) that are individually controlled for each nozzle (16), wherein the flow rate of each nozzle (16) is regulated by changing the duration of the open state of the corresponding electrovalve (15). Means are provided to generate alarms whenever the speed of at least one nozzle is inadequate, thereby enabling correction measures to be carried out.
