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 arranged in succession on frame so that they may be adjusted in longitudinal, transverse and vertical planes. Working tools are made in the form of A-hoe, hoes-shavers, disk-type moldboards with protective housings, rotary hoe, and spring-tooth harrow. During advancement of apparatus, A-hoe and hoes-shavers mellow soil, undercut and comb out weeds over the whole width of spacings up to protective zones. Disk-type moldboards with protective housings cover weeds with dry soil in protective zones of cultivated plants. Rotary hoe mellows soil and combs weeds over the whole width of spacing up to protective zones. Coiled free ends of steel strips provide additional crumbling of soil and removal of weeds, as well as level soil in spacings. Such construction allows fine-grain dry surface soil layer to be formed upon cultivation of soil in spacings and, as a result, facilitates accumulation and retention of soil moisture and efficient usage of it by creating favorable conditions for growing and development of cultivated plants. EFFECT: increased efficiency, enhanced reliability in operation and increased yield. 4 dwg
