摘要：
FIELD: agriculture.SUBSTANCE: irrigation system comprises self-propelled trucks (11) with hydraulic actuators, an irrigation pipe (3) with water outlets, the water supply facility, devices of surface irrigation. The water supply facility comprises a drum (2) and a unit of connecting the hoses to the pipe (3) of the device. The drum (2) comprises two sections with two water-supply hoses coiled on them. The drum (2) is made with the ability to rotate freely on the pipe (3) of the device. The drum (2) is provided with a brake (17). The unit of connecting the hoses to the pipe (3) of the device comprises a two-way check valve (6). The two-way valve (6) comprises one outlet (7), and two inlets (8, 9) with slots (10, 11) made of an elastic material. Through-holes in the slots (10, 11) are alternately overlapped with the ball valve (12). The ball valve (12) is made with the ability to move freely from one slot to another in the guides (13). The inlets (8, 9) are connected to the first (14) and the second water-conducting hoses (15). The outlet (7) is connected to the cylinder with seals (16), which is located on the pipeline in the area of water-supply windows with the ability to rotate around the pipeline. Hose laying device comprises two guide wheels (18, 19) and stops (20). The guide wheels (18, 19) are located on the shaft (21) with the possibility of free rotation. The stops (20) prevent the movement of the drives on the shaft (21) in the axial direction and are pivotally mounted on the pipe (3) of the device of the brackets (22) with holes. In the holes the ends of the shaft are located with the ability to move freely in the holes in the axial direction. The first hose (14) is wound on the drum (2) in one direction and is placed in the first guide wheel (18). The second hose (15) is wound on the drum (2) in the opposite direction and is placed in the second guide wheel (19). Both hoses are provided on both ends with the pipes and are connected to the hydrants of the
