Устройство включает раму с установленным на ней барабаном 2 с осью 3 и рабочими органами 4, выполненными в виде пустотелых зубьев. Устройство снабжено шарнирно прикрепленными по концам оси 3 внутри барабана 2 подпружиненными с помощью пружины 5 и жестко закрепленного на оси 3 рычага 6 коромыслами 7, в нижней части которых закреплены сегменты 8 с тросовыми нитями 9, при этом тросовые. нити 9 натянуты между сегментами 8,а рабочие 'органы 4 прикреплены к барабану 2 посредством пружинных пластинок 10, один конец которых прикреплен к барабану 2 жестко, а другой - посредством гибкой связи 11.The device includes a frame with a drum 2 mounted on it with an axis 3 and working bodies 4 made in the form of hollow teeth. The device is equipped with pivotally attached at the ends of the axis 3 inside the drum 2 spring-loaded with a spring 5 and rigidly fixed to the axis 3 of the lever 6 rocker arms 7, in the lower part of which segments 8 are fixed with cable strands 9, while cable. the filaments 9 are stretched between segments 8, and the working bodies 4 are attached to the drum 2 by means of spring plates 10, one end of which is attached to the drum 2 rigidly, and the other by means of a flexible connection 11.

Устройство для аэрации дерновых почв работает следующим образом,A device for aeration of soddy soils works as follows,

При перекатывании барабана 2 рабочие органы 4 под тяжестью устройства погружаются в почву, при этом пружинные пластинки 10 прижимаются к поверхности барабана 2. При выходе рабочих органов 4 из почвы пружинные пластинки 10 позволяют отходить им на расстояние, определяемое гибкой связью 11, которое обеспечивает уменьшение подрезания (повреждения) дернины тыльной стороной рабочего органа вследствие того, что гибкая связь позволяет рабочему органу занимать положение, близкое к параллельному оси формируемой лунки в почве.When rolling the drum 2, the working bodies 4 under the weight of the device are immersed in the soil, while the spring plates 10 are pressed against the surface of the drum 2. When the working bodies 4 come out of the soil, the spring plates 10 allow them to move to a distance determined by the flexible connection 11, which reduces cutting (damage) of the turf by the back side of the working body due to the fact that the flexible connection allows the working body to occupy a position close to the parallel axis of the formed hole in the soil.
