Abstract

Изобретение относитс к сельскохоз йственному машиностроению и может быть использовано в почвообрабатывающих фрезах дл работы, например, в теплице. Цель изобретени - повышение качества поверхностной обработки почвы за счет ее дополнительного измельчени на естественные структурные элементы. Рабочий орган почвообрабатывающей фрезы содержит закрепленные на ступицах 2 вала 1 ножи 4. Каждый нож имеет радиально направленный участок 6 и отогнутое от него крыло 7. Вдоль тыльной кромки 8 крыла 7 установлены рыхлительные элементы, выполненные в виде пластин 10. Кажда пластина 10 направлена от плоскости крыла 7 к валу 1 рабочего органа, и ее плоскость расположена под острым углом к продольно-вертикальной плоскости, в которой расположены ступицы 2 данного ножа 4 с вершиной угла в направлении вращени этого ножа. Пластина 10 соединена с крылом 7 посредством дополнительного участка 9 его рабочей поверхности , перемеща сь по которому отрезанна и размельченна стружка почвы разбиваетс дополнительно на более мелкие , естественной структуры элементы. 2 ил. fOVXThe invention relates to agricultural machinery and can be used in tillage mills for work, for example, in a greenhouse. The purpose of the invention is to improve the quality of surface treatment of the soil due to its additional grinding into natural structural elements. The working body of the tillage cutter contains knives 4 fixed on the hubs of 2 shaft 1. Each knife has a radially directed section 6 and a wing bent away from it 7. Along the rear edge 8 of the wing 7, loosening elements are installed, made in the form of plates 10. Each plate 10 is directed from the plane the wing 7 to the shaft 1 of the working body, and its plane is located at an acute angle to the longitudinal-vertical plane in which the hubs 2 of this knife 4 are located with the apex of the angle in the direction of rotation of this knife. The plate 10 is connected to the wing 7 by means of an additional portion 9 of its working surface, moving along which the cut and crushed soil chips are further divided into smaller, natural structure elements. 2 Il. fOVX
