WORKING TOOL FOR BULK MATERIAL SPREADER (VERSIONS) Russian patent published in 2004 - IPC

FIELD: agricultural engineering, in particular, centrifugal spreaders for bulk materials, such as mineral fertilizers. SUBSTANCE: working tool has deflector with shield deflected in horizontal plane from longitudinal axis of spreader on the side of its frame for an angle of 0-20 deg from axis of centrifugal disk 1 extending perpendicular to longitudinal axis of spreader to side opposite to direction of rotation of disk. Working tool is additionally provided with centrifugal disk equipped with deflector. Disks are arranged symmetrically with respect to longitudinal axis of spreader, and curved portions of deflectors are arranged adjacent to one another. Ends of curved portions of deflectors of each disk are arranged at an angle of 70-90 deg and oriented to side opposite to direction of rotation of disks from line extending through disk axes. EFFECT: uniform distribution of bulk material over soil surface and increased width of spreader. 3 cl, 4 dwg
