UNIVERSAL MOUNTED DUSTING DEVICE Russian patent published in 2024 - IPC A01M9/00 

FIELD: agricultural machine building.

SUBSTANCE: universal mounted dusting device comprises a hopper with a semi-cylindrical bottom, an auger shaft installed in its lower part and a beater drum in the middle part. A fan is installed on the frame to create an air flow, an air mixture outlet window is connected to a nozzle installed on the casing. At the bottom of the hopper there are two identical unloading windows with shutters installed on one axis, symmetrically concentrated to the inlet window of the fan casing installed under it. Discharge windows of trapezoidal shape are made so that smaller sides are directed to opposite sides, parallel sides are perpendicular to their common axis, note here that smaller side of discharge opening features 5–8 cm, larger side 10–12 cm and length 8–14 cm. Smaller sides of the discharge openings are installed at a distance equal to the diameter of the circumference of the inlet opening of the fan casing. On the auger shaft above the unloading openings there are pin drums with a diameter equal to the auger diameter, and width equal to length of unloading window with 4–6 pins along circumference in 4–6 rows, turned relative to each other at angle β=10–15° and with distance between rows of 2–3 cm. Fan wheel of semi-closed type with blades of straight or curved profile is made with upper inlet window of fan casing, which is equal in diameter to inlet window of fan. Nozzles are installed on the left and right outlet windows of the fan casing. A cover is installed on the rear window of the fan casing. When processing dense continuous plantings of plants, the cover should be open, and during double-sided processing of rows of plantation gardens—closed.

EFFECT: device provides versatility, high uniformity of drug delivery, efficiency, low material consumption and power consumption.
