EROSION-PREVENTIVE TILLAGE TOOL Russian patent published in 1999 - IPC

FIELD: agriculture. SUBSTANCE: tillage tool has frame 1, bar 3, plow bodies 4,5,6,7,8 fixed on bar 3 at an angle to tillage tool longitudinal axis. Rear plow body 8 has shortened moldboard and adjacent plow body 7 has subsoiler. First disk battery 9 is fixed on frame 1 at an angle to longitudinal axis 13 of tillage tool and second disk battery 12 is positioned at opposite side of tillage tool longitudinal axis 13 extending between plow bodies 7 and 8. Terminating disk member 10 of disk battery 9 is arranged in front of plow body 7. Battery 12 is positioned at an angle to axis 13, with apex of angle being oriented to rear part of tillage tool. Plow body 8 is offset rearward relative to plow body 7 to define space 14 extending along axis 13. Terminating disk member 15 of disk battery 12 is positioned in front of plow body 8 and behind plow body 7. Working members 10,11 of disk battery 9 undercut stubble in front of plow bodies 5,6 and feed it to axis 13 of tillage tool to form outer stubble roll opposite working member 15 and, partially, opposite working member 16 of battery 12. Working member 15 of battery 12 undercuts stubble in front of plow body 8 and working members 16,17 undercut stubble in zone adjacent to side peripheral parts of plow bodies. Stubble mass undercut by working members 15,16,17 and stubble roll seized by working member 15 and partially by working member 16 are fed by working member 15 onto mellowed plow sole in furrow. Plow body 8 forms earth roll above stubble roll. During subsequent tillage tool pass, its plow bodies 4 and 5 plow strip, from which stubble had been undercut by working members 16,17 during previous pass. EFFECT: improved water retention and reduced power consumption. 2 dwg
