DEVICE USED FOR APPLYING, TOGETHER WITH IRRIGATION WATER, MICROELEMENTS, CHEMICAL AMELIORANTS, HERBICIDES, PESTICIDES AND MACRO-FERTILISERS IN DRIP IRRIGATION SYSTEMS, MOBILE ROUND- AND FRONT-DIRECTED IRRIGATION MACHINES, AND IN MULTI-SUPPORT POSITION-DIRECTED IRRIGATION MACHINES OF FRONT MOVEMENT

FIELD: agricultural industry; mechanics. ^ SUBSTANCE: device consists of free-flow capacity, level meter, inlet and outlet connection pipes, distributing pipeline, shutter, pressure control, fine filter with pressure gauges, and venture tube with shutoff valves. Outlet connection pipe of free-flow capacity is installed therein so that it can move along its height thus increasing or decreasing the level of solution by means of a float. The latter has the possibility of filling the cavity with ballast. The float is made in the form of a flat ring with a hole made in the centre. In the lower plane of the float there arranged are stops made in the form of racks used for restricting the extreme lower position at the bottom of free-flow capacity. The end of a flexible hose of the outlet connection pipe is fixed in the float hole by means of elastic rings. ^ EFFECT: uniform distribution of liquid macro-fertilisers, chemical ameliorants, microelements, pesticides and herbicides in the irrigated area, and increase in productivity of agricultural crops used in irrigated agriculture. ^ 7 dwg
