Abstract

Изобретение относитс к сельскохоз йственному машиностроению и может быть использовано в оруди х дл обработки почв, содержащих твердые включени . Цель изобретени - снижение энергоемкости обработки почвы с твердыми включени ми. Рабочий орган почвообрабатывающей фрезы содержит горизонтальный вал 1 со ступицами 2, кажда из которых выполнена из двух дисков 6. Между дисками 6 на шарнирах 4 установлены ножи 3. Грани 10 всех ножей 3, обращенные к валу 1, сопр жены с наружной поверхностью круглого пружин щего кольца 11 так. что это кольцо имеет вид многоугольника с закругленными углами. На ступице 2 имеетс упор 9 дл каждого из ножей 3, который размещен в направл ющей выемке 8, выполненной в монтажной части этих ножей. При встрече ножа в почве, например, с камнем зуб 3 давит на кольцо 11, в результате чего оно прогибаетс вовнутрь . Энергоемкость такого прогибани очень невелика. 2 ил. kThe invention relates to agricultural machinery and can be used in tools for treating soils containing solid inclusions. The purpose of the invention is to reduce the energy intensity of tillage with solid inclusions. The working body of a tillage cutter contains a horizontal shaft 1 with hubs 2, each of which is made of two discs 6. Knives 3 are mounted on hinges 4 between disks 6. The edges of all 10 knives 3 facing the shaft 1 are aligned with the outer surface of the round spring rings 11 like that. That this ring has the shape of a polygon with rounded corners. On the hub 2 there is an abutment 9 for each of the knives 3 which is housed in a guide recess 8 formed in the mounting portion of these knives. When a knife meets in the soil, for example, with a stone, the tooth 3 presses against the ring 11, as a result of which it bends inwards. The energy intensity of such deflection is very small. 2 Il. k

Claims

Claim

The working body of the tillage cutter, containing a horizontally located shaft with hubs rigidly fixed on it, each of which has several knives, each of which is mounted on the hub by means of a hinge, a spring compression element, a guide recess and an abutment, characterized in that, with In order to reduce the energy consumption of soil cultivation with solid inclusions, the hinge of each knife is located on the front section of its mounting part, the guide recess is made on the rear section of this part of the knife, the emphasis is placed on a cutting recess, and all knives mounted on the same hub are connected with one common spring compression element, which is made in the form of a round ring concentrically relative to the shaft, located between the faces of the mounting parts of the knives facing the shaft in the same plane with the said faces and mating across the entire plane of each of these faces, and the radius of the spring ring is greater than the distance from the longitudinal axial line of the shaft to each of the mentioned faces, while the hub is made in the form of two parallel rigidly with of the connections between a disk and spring ring and the mounting portion of the blades are mounted between these wheels.
