Abstract RU 2065690 C1

FIELD: agriculture. SUBSTANCE: irrigation hose is made in the form of flexible high-pressure pipe 1 with length of about 20 m. Large end opening of pipe 1 is dead closed. Holes 3 are staggered or arranged in helical line on pipe portion spaced from pipe end by distance equal to or exceeding 1-3 of pipe diameter. Holes are arranged such that their total section area exceeds effective section of pipe 1. Thin-walled cylindrical casing 5 made from resilient material is attached to pipe portion spaced from hole 3 most distal from pipe end by distance of 2-10 cm. Casing 5 is fixed by coupling device. Length of casing 5 exceeds length of pipe portion with holes 3 by 2-5 times. Casing 5 may be made in the form of truncated cone. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 3 dwg
