FIELD: agriculture. ^ SUBSTANCE: present invention pertains to agriculture and can be used for irrigating rectangular fields. The mobile irrigation device has two rows of interconnected pipe sections. Each section has a part, supported by a self-moving prop with an actuator, and a free end. The pipe sections are joined by flexible connectors. The connectors are at the free end of one of the sections and the part supported by the neighbouring section. The irrigation device can have a mechanism for controlling the actuator of props, located at the ends of the pipe sections. Each control device has a closing switch, connected through detecting elements to the actuator of props and sensing angular displacement of pipe sections. The last pipe section from the interconnected row has an extra self-moving prop with an actuator. Each outermost pipe section has a water intake, periodically connected to hydrants of the first, second and third and subsequent positions on the water-carrying pipe of a closed irrigation network, laid down along the long sides of the irrigated rectangular field. One water intake at the end of the pipe section is put into the transport position, at the same time as another water intake at the other end of the outermost pipe section is put into working position. The hydrants on the water-carrying pipe are displaced by half a step between hydrants of the first, second, third and subsequent positions of the first water intake. Each outermost self-moving prop with an actuator has a hydro-support. The hydro-support is mounted opposite the motor reducer on the supporting girder between power-driven support wheels. ^ EFFECT: mobile irrigation device provides for overhead irrigation of rectangular fields using multi-support all-round irrigation machines and reduces capital expenditure on constructing irrigation networks. ^ 15 cl, 6 dwg |
