TILLAGE TOOL Russian patent published in 2001 - IPC

FIELD: agricultural engineering. SUBSTANCE: tillage tool has frame, carrier wheels, hydraulic cylinder for lowering and raising of tillage tool, central pivot joint with rotary frame and vibration followers, disk battery section and flat hoes. Front and rear pairs of disk batteries are arranged asymmetrically one with respect to the other. Deep cultivators are arranged on rotary frame of front and rear disk batteries, directly under battery disks. Wing opening angle of cultivators is equal to such angle of each pair of disk batteries. Such construction allows soil tillage quality to be increased, tillage tool firmness in longitudinal-vertical plane of advancement to be increased and, as a result, disks to be prevented from withdrawal from soil. Besides, working tools are self-cleaned from adhered soil and clogged plant remains. Tillage tool may be used for presowing soil tillage, as well as for soil rotavation in gardens, vineyards and fruit crop nurseries. EFFECT: simplified construction and increased efficiency by reduced draft and improved quality of tilled soil. 2 cl, 4 dwg
