Abstract

Изобретение относитс к сельскохоз йственному машиностроению и может быть использовано в оруди х дл обработки почвы в садах, при предпосевной и междур дной обработке почвы. Цель изобретени повышение качества обработки почвы за счет стабилизации хода по глубине. Фрезерный барабан содержит несколько дисков 2, закрепленных на валу 1. По периферии каждого диска 2 установлено несколько режущих рабочих элементов 3, 4 или 5. 6. Каждый из элементов 3-6 представл ет собой пластинчатую стойку 7 с режущей передней кромкой и хвостовик 8 с режущей передней кромкой. В верхней части стойки 7 установлен поперечный нож 9, а в верхней части хвостовика 8 - поперечный нож 10. Ножи 9, 10 стоек 7 и хвостовиков 8 поочередно направлены в разные стороны от плоскости диска 2. на котором закреплен данный режущий элемент (3 - 6). Отношение длины хвостовика 8 и стойки 7 0,6 - 0,75. Режуща кромка хвостовика 8 отклонена от радиального направлени на угол, вдвое больший, чем режуща кромка стойки 7.1 з.п. ф-лы, 5 ил. (ЛThe invention relates to agricultural machinery and can be used in tools for tillage in gardens, pre-sowing and inter-row tillage. The purpose of the invention is to improve the quality of tillage by stabilizing the course in depth. The milling drum contains several discs 2 fixed on the shaft 1. On the periphery of each disc 2 there are several cutting working elements 3, 4 or 5. 6. Each of the elements 3-6 is a plate rack 7 with a cutting leading edge and a shank 8 s. cutting front edge. In the upper part of the rack 7, the transverse knife 9 is installed, and in the upper part of the shank 8 - the transverse knife 10. The knives 9, 10 of the racks 7 and the shanks 8 are alternately oriented to different sides of the plane of the disk 2. On which this cutting element is fixed (3 - 6 ). The ratio of the length of the shank 8 and rack 7 0,6 - 0,75. The cutting edge of the shank 8 is deflected from the radial direction by an angle that is twice as large as the cutting edge of the 7.1 pivot. f-ly, 5 ill. (L

Claims

Claim

1. A milling drum of a tillage cutter containing a shaft with a horizontal axis of rotation and cutting elements radially mounted on the shaft by means of disks, each of which has a stand and a shank, the cutting edges of which are inclined in the direction opposite to the direction of their rotation, and mounted in the upper part racks are a transverse knife, while the transverse knives on adjacent racks are directed from the plane of the disk in opposite directions, so that, in order to improve the quality of tillage, due to the stabilization of the stroke in depth, each cutting element is equipped with an additional transverse knife installed in the upper part of the shank, and the transverse knives on adjacent shanks are directed from the plane of the blade c. opposite sides, while the angle of inclination of the cutting edge of the shank is twice as large as the angle of inclination of the cutting edge of the rack relative to the radius line of the described circle through the front edge of the corresponding transverse knife, and the ratio of the length of the shank and the radial length of the working part of the rack of the cutting element is 0.6 0.75 ,

2, Drum by π. 1, characterized in that the transverse knives 5 of each cutting element mounted on each of the extreme disks are directed in opposite directions from the plane of the disk.
