DOUBLE TUBING DISTRIBUTING OF FERTILIZERS AND PESTICIDES FIXED TO AERIAL STRUCTURE OF CENTRAL PIVOT, THROWN AND CONTROLLED BY AUTOMATION DEVICES CONSIST OF GATE VALVES, PRESSURE VALVES, SOLENOID VALVES AND CHECK VALVES
“Double tubing distributing of fertilizers and pesticides fixed to aerial structure of central pivot, thrown and controlled by automation devices consist of gate valves, pressure valves, solenoid valves and check valves”, refers to a device to be installed in a central pivot (P), comprehended by a main tubing (1), due supported and fixed by staples to aerial structure (14) of central pivot, responsible by derivation and conduction of the solution to the final ending of the pivot, presenting derivations of the solution in the “T” (25) of the main tubing (1) with the towers (15) to assist the automation device (S) comprehended by gate valves (4), pressure valves (5), solenoid valves (6) and check valves (7), from where flexible hoses (13) derive to secondary tubing (2) of distribution, with adjustable heights in each segment through steel cables like suspension strings (10) and steel cables masters (11) activated by a winch turnpike (16), or by remote control, that pulverize the solution through the sprays nozzles (3), with anti-dripping valves (26), equally spaced, and the secondary tubing (2) receives the solution by the two endings, where gate valves (4), line filters (12) and sucker valves (17) were installed, being a main pumping (18) responsible by supplying of the equipment with the solution prepared in the tanks (19), passing by a device with pressure valve (20), another device of central filtering, self-cleaning filters (21), being the reservoir tanks (19) fueled of water from the main pipeline (22) pumped by an auxiliary motor-pump (24) installed with the water source (river or dam).
