COTTON-PICKING APPARATUS Russian patent published in 1995 - IPC

FIELD: agricultural engineering. SUBSTANCE: apparatus has chamber 1 with double walls 2. The apparatus working tool is magnetic fluid 3 circulating between the double walls. The fluid acts selectively on cotton bolls. Magnets 10 installed in the discharge zone of chamber 1 create static magnetic fields, and solenoid system 11 creates alternating magnetic field. As the fields change density of magnetic fluid 3, the latter is atomized in space 6 of chamber 1. Holes 5 in wall 2 of chamber 1 let the fluid out onto the cotton plants. EFFECT: higher efficiency. 2 dwg
