FIELD: agriculture.SUBSTANCE: invention relates to agriculture and can be used for shielding the pastures from sun rays. The method of shielding from sun rays at pastures includes the use of flying structures (1) lighter than air over the places of animals' location. For placement of structures (1) at a given height and position the hot air is used inside the structures (1), the direction of wind flow, and flexible rods (5). The device of shield from the sun rays at the pastures consists of one or more flying structures (1) of soft toroid-shape membranes which are lighter than air, with bypass valves (2), flexible rods (5), and winches (7). The device comprises a shielding grid (3), compartments (6) of the ballast fluid, hoses of the compartments (6) of the ballast fluid, an air compressor (9), a water pump (11), an actuator (8), a transport trolley (4), a self-contained power-supply source. The carrying shielding grid (3) is attached along the inner perimetre of the flying structures (1). The compartments with the ballast fluid (6) and an air compressor (9) are placed on the upper part of the flying structure (1). The actuator (8) of the air compressor (9), water pump (11), winch (7) and wheels, the self-contained power-supply source and the winch (7) are placed on the transport trolley (4). The output of the water pump (11) is connected to the compartments (6) of the ballast fluid with the hoses of the compartments (6) of the ballast fluid. The drive provides the operation of the air compressor (9), the water pump (11) and the wheels.EFFECT: increased shielded pasture areas, adaptation of the device to changing weather and climatic conditions.4 cl, 3 dwg |
