Apparatus for applying liquid fertilizers e.g. nitrogenous fertilizers, to roots of plant, has crank mechanism for actuating punching element, and driving device for driving trapping equipment, which is coupled to tractor unit

NOVELTY – The apparatus has a punching element (h) provided with a cylindrical rod (i) and a conical tip (j). A guide part carries out vertical movement of the rod. A crank mechanism (g) actuates the punching element, which is coupled to a crank of a crank mechanism by an articulation part (n). A drum cam mechanism (d) is provided with a rotor, which is fixed with a guide channel (e) and a guide carriage (f). A power source drives a drum and a punch mechanism. A driving device drives the crank mechanism and a trapping equipment, which is coupled to a tractor unit. USE – Apparatus for applying liquid fertilizers e.g. nitrogenous fertilizers and insecticides, to roots of plant. ADVANTAGE – The apparatus improves adhesion of the liquid fertilizer, and breaks a straw barrier from harvest without burning. DESCRIPTION OF DRAWING(S) – The drawing shows a schematic view of an apparatus for applying liquid fertilizers to roots of plant. ‘(Drawing includes non-English language text)’ Drum cam mechanism (d) Guide channel (e) Guide carriage (f) Crank mechanism (g) Punching element (h) Cylindrical rod (i) Conical tip (j) Articulation part (n)
