Abstract

A device for cutting or felling trees comprising a rotating blade of uniformly increasing width in the shape of a partial, truncated cone mounted on the edge of a base disk. The blade does not extend completely around the base disk. Cutting is performed by attacking the tree at an angle and rotating the blade in the direction of increasing width.

Изобретение относитс  к устройствам дл  срезани  деревьев и может .. быть использовано в лесной промышленности .The invention relates to a device for cutting trees and can be used in the forest industry.
Известно устройство дл  срезани  деревьев, содержащее привод и поворотный режущий орган, выполненный в виде переменного по ширине ножа }.A device for cutting trees is known, which contains a drive and a rotary cutting body, made in the form of a knife width variable}.
Однако известное устройство характеризуетс  недостаточно высокой производительностью .However, the known device is not sufficiently high performance.
Цель изобретени  - повышение производительности .The purpose of the invention is to increase productivity.
Цель достигаетс  тем, что нож выполнен в виде части боковой поверхности усеченного конуса.The goal is achieved by the fact that the knife is made as part of the flank cone side surface.
На фиг. 1 изображен режущий орган, вид сверху; на фиг. 2 - устройство дл  срезани  деревьев.FIG. 1 shows a cutting organ, top view; in fig. 2 - device for cutting trees.
Устройство содержит привод 1, основание 2 с режущим органом 3 раму 4 с захватами 5.The device contains a drive 1, a base 2 with a cutting body 3, a frame 4 with grippers 5.
Устройство работает следующим образом .The device works as follows.
Приводом 1 основание 2 поворачива етс  таким образом, чтобы режущий орган 3 был обращен в сторону ствола дерева минимальной шириной ножа. Затем устройство подводитс  к дереву, которое зажимаетс  захватами 5. .Вклю .чаетс  привод 1 и осуществл етс  поворот-основани  2, при этом режущий орган 3, поворачива сь за счет постепенного увеличени  ширины лезви , Перерезает ствол дерева.By drive 1, the base 2 is rotated so that the cutting body 3 faces the tree trunk with a minimum width of the knife. The device is then brought to the tree, which is clamped by the claws 5.. The drive 1 is turned on and the base 2 is rotated, while the cutting body 3, turning by gradually increasing the width of the blade, cuts the tree trunk.
