DEVICE FOR UNIFORM DISTRIBUTION OF HYDROSORBENT WHEN PLANTING POTATOES Russian patent published in 2025 - IPC A01C9/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, particularly, to potato planting machines. Device for uniform distribution of hydrosorbent during planting of potatoes contains a ploughshare, a hopper for hydrosorbent, at the bottom of which there is a dosing device, a knife-feeder. Dosing device is made in the form of a dosing coil. In the lower part of the feeder knife, a duckfoot is installed below the level of ploughshare by 10…12 cm. In the rear wall of the knife-feeder there is an air swirler, which is tightly connected to the receiver through a tip and an air duct. Sweep has a fixed bottom from below, which is located higher than the edges of its blades, a reflector plate fixed along its entire width and a movable flap installed on the axis with formation of a cavity between it and the reflector plate for mixing air with the hydrosorbent. Width of the movable flap is greater than the width of the duckfoot, and the angle between the bottom and the reflector plate is more than 60°. Cavity between the plate-reflector and the movable shutter is a mixing chamber.

EFFECT: use of the invention when planting potatoes makes it possible to increase crop capacity of potatoes in arid regions by means of uniform strip application of hydrosorbent below the level of planting of tubers.
