FIELD: agriculture; machine building.SUBSTANCE: invention relates to agricultural machine building, in particular to devices for local subsurface and surface application of liquid agrochemicals installed on different field units. Device frame is equipped with vessel for liquid agricultural chemical, guide, air pump driven by tractor PTO, interconnected by pneumatic drives receiver with pressure regulator, as well as step motor. Receiver is connected by air duct with reservoir for agrochemicals. Guide has nozzles with valves, rigidly fixed actuating device and is connected to the step motor. Actuating device is connected through a pressure sensor both with a liquid agricultural chemical vessel and output of the control unit inputs of which receive signal from the unit speed sensor and signal from GPS receiver. Actuating device is connected to vessel for liquid agrochemicals through valve, and the valve is connected through a step motor with control unit output.EFFECT: such design solution is aimed at improving control accuracy of dose introduced liquid agrochemicals on a specific area of treated field and quality of control dose introduced liquid agrochemicals.1 cl, 1 dwg |
