Abstract

Изобретение относитс к сельскохоз йственному машиностроению, в частности и ротационным режущим аппаратам кормоу- борочных машин. Цель изобретени - повышение эксплуатационной надежности путем снижени скорости вращени ротора. Ротационный режущий аппарат содержит корпус 1, приводной ват 2 и диск 6 с закрепленными на нем режущими элементами 7 Новым в аппарате вл етс выполнение режущих элементов из упруго-эластичного материала , которые отгибаютс механизмом дл отгиба и распр мл ютс при в зону резани растений. Механизм отгиба режущих элементов выполнен с направл ющей по кривой линии, например архимедовой спирали. Механизм отгиба режущих элементов представл ет собой или систему роликов 8, или желоб. Предусмотрен р д признаков дл снижени трени в паре механизма отгиба и режущих элементов. Режущие элементы выполнены в нескольких вариантах. 3 з.п.ф-лы, 5 ил.FIELD OF THE INVENTION The invention relates to agricultural machinery industry, in particular, to rotary cutting machines of forage machines. The purpose of the invention is to increase operational reliability by reducing the speed of rotation of the rotor. The rotary cutting apparatus comprises a housing 1, a drive wat 2 and a disk 6 with cutting elements fixed on it. 7 New in the apparatus is the making of cutting elements from an elastic material that are folded over by a mechanism for limb and straightened in the cutting zone of plants. The mechanism of the limb of the cutting elements is made with a guide along a curved line, such as an Archimedean spiral. The mechanism of the limb of the cutting elements is either a system of rollers 8 or a chute. A number of features are provided to reduce friction in the pair of the bend mechanism and the cutting elements. Cutting elements are made in several versions. 3 hp ff, 5 ill.
