TILLAGE TOOL Russian patent published in 2002 - IPC

FIELD: agricultural engineering. SUBSTANCE: apparatus has first row of needle-type disks, working tools made in the form of A-hoes and/or blade-hoes arranged in three rows, second row of needle-type disks, device for shaking roots of weeds combed from soil and for cleaning second row working tools from plant remains, with all mentioned equipment being arranged in succession on frame. Second row needle-type disks are arranged in non-operating position, i.e., disk needles are bent in direction opposite to direction of advancement of tillage tool. Second row needle-type disks and shaking device are rotated by independent or synchronous tractor power shaft through cardan shaft, reducer and infinitely variable V-belt transmission mechanism or chain transmission mechanism with interchangeable sprockets. Second row needle-type disks are rotated in direction opposite to direction of advancement of tillage tool. Rotational speed of needle-type disks exceeds speed of progressive movement of tillage tool by 8-32%. Device for shaking weed roots from soil and for cleaning working tools from plant remains is rotated in direction coinciding with direction of advancement of tillage tool. Rotational speed of this device exceeds that of second row needle-type disks by 1.2-2.0 times. Such construction of tillage tool allows weed roots to be effectively removed and plant remains to be left on soil surface. EFFECT: increased efficiency by improved protection of soil from wind and water erosion and improved crop yield. 1 dwg
