APPARATUS FOR CULTIVATING SOIL IN SPACINGS IN THE PROCESS OF GROWING TILLED AND OTHER FARM CROPS Russian patent published in 2000 - IPC

FIELD: agriculture. SUBSTANCE: apparatus has frame and working tools mounted in succession on frame so as to be adjusted in longitudinal, transverse and vertical planes. Working tools are made in the form of rotary hoe, disk-type moldboards with protective housings, A-hoe, hoes-shavers, and spring-tooth harrow. During advancement of apparatus, rotary hoe mellows upper soil layer and combs weeds out of it. Disk-type moldboards with protective housings slightly cover combed out weeds with dry soil in protective zones of cultured plants. A-hoe and hoes-shavers mellow soil and undercut weeds over the whole width of spacings up to protective zones. Coiled free ends of steel strips provide crumbling of soil and withdrawal of weeds, as well as leveling of soil surface. Such construction allows fine-grain dry surface soil layer to be formed upon cultivation of spacings. As a result, weeds are effectively removed from soil and soil moisture is accumulated and retained in soil to create favorable conditions for growing and development of cultured plants. EFFECT: increased efficiency, enhanced reliability in operation and increased crop yield. 4 dwg
