AUTOMATED DEVICE FOR VENTILATION OF FLAX-STRAW ROLLS Russian patent published in 2024 - IPC A01F25/08 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to the field of agricultural machine building, namely to devices for preservation of wet flax stalks in the form of rolls. Automated device for venting rolls of flax-straw comprises a base with a hollow cylinder with holes vertically fixed in the centre, which holes are arranged along its height and diameter, wherein the upper part of the hollow cylinder has a cone protruding above the upper cover, and the lower part of the hollow cylinder is connected by an air duct with a fan, inside the air duct there is a working nozzle in which a preservative sprayer is installed, connected to a dosing valve by a hose through a filter with an intake tube installed inside the reservoir with a preservative, inside the roll along its height there are preservative concentration sensors, the electrical outputs of which are connected to the measuring unit, electric output of the latter is connected to control device, to which an actuating device for controlling a fan and an actuating device for controlling a metering valve are connected, respectively connected to the fan and metering valve.

EFFECT: invention makes it possible to automate the process of saturation of a roll of flax-straw with preservatives, to reduce power consumption and to reduce consumption of preservatives due to automatic shutdown of the preservative and air supply when the required concentration of the preservative is achieved inside the rolls of flax-straw.
