SPRAYER FOR PROCESSING BULRUSH, GROWING IN ELEMENTS OF IRRIGATION SYSTEM OF RICE BAYS

摘要

FIELD: agriculture; machine building.;SUBSTANCE: invention can be used for chemical protection of rice bays against bulrush, growing in irrigation system elements. Sprayer for bulrush processing includes tank, pump, hydraulic communications, cleaning system and rotary rod with spray nozzles. On frame of sprayer behind vessel is support post. By one end rotary bar is hinged to upper part of post. Rod is located above sprayer tank along unit axis of symmetry. Rod is made movable by handle in horizontal plane at angle close to 90°. Handle is arranged on lower part of support post. In vertical plane rod moves by hydraulic cylinder. Hydraulic cylinder is arranged between support post and rod flange. Post is equipped with pin to lock rod. Arrangement of sprayers on bar corresponds to parabola produced according to formula y=-0.075471698x²-0.015094339x+4.8.;EFFECT: possibility of processing bulrush, growing in elements of irrigation system of rice bays.;1 cl, 2 dwg
