SOIL LOOSENER

摘要

FIELD: agricultural engineering. SUBSTANCE: proposed soil loosener has symmetrical inclined blade carriers connected in lower portion by share to form variable approach angle. Blade carriers are made in form of two mating arcs of circumference and are connected to share so that their concave sides are directed inwards the loosener forming gradually decreasing approach angle relative to vertical in lower portion and gradually increasing approach angle in upper portion. Parameters of loosener are selected to prevent wedging of soil between loosener blade carriers. EFFECT: enhanced quality of soil loosening; reduced power consumption.
