(54) КОРЧЕВАТЕЛЬ ПНЕЙ(54) KORCHEVELA KNOTS

tt

Изобретение относитс к машинам дл корчевани пней и может быть использовано в мелиорации при освоении новых земель из-под леса и в лесной промышленности.The invention relates to machines for uprooting stumps and can be used in amelioration in the development of new lands from under the forest and in the forest industry.

Известны устройства дл вырезани пней, включающие режуш.ий орган в виде установленной в направл ющей кольцевой фрезы, привод дл вращени и привод дл поворота 1 .Devices for cutting stumps are known, including a cutting organ in the form of an annular cutter installed in the guide, a drive for rotation and a drive for turning 1.

Однако такие устройства имеют низкий КПД и быстро изнашиваютс . Кроме того, они недостаточно очищают пни от почвы.However, such devices have low efficiency and wear out quickly. In addition, they are not sufficiently clean stumps from the soil.

Известны также устройства дл вырезани пней, включающие Г-обфазную раму, режущий орган в виде двух криволинейных рычагов с режущим инструментом, установленных на валу привода дл вращени с возможностью поворота и соединенных с приводом дл поворота при помощи подвижной вдоль оси вала муфты и кулисного механизма 2.Stump cutting devices are also known, including a G-shaped frame, a cutting body in the form of two curved levers with a cutting tool mounted on a drive shaft for rotating and rotatable and connected to a drive for turning using a coupling along the shaft axis and a coupling mechanism 2 .

Недостатком данных устройств вл етс то, что кулисный механизм не позвол ет увеличить количество рычагов более двух дл повышени производительности и обуславливает их расположение в перпендикул рнойThe disadvantage of these devices is that the rocker mechanism does not allow an increase in the number of levers of more than two to increase productivity and causes their location in perpendicular

К оси поворота плоскости, а это приводит к тому, что дл удалени стружки приходитс увеличивать ширину режущего инструмента , а следовательно, увеличивать расход энергии на резание.To the axis of rotation of the plane, and this leads to the fact that in order to remove chips, it is necessary to increase the width of the cutting tool and, consequently, increase the power consumption for cutting.

Цель изобретени - повыщение производительности .The purpose of the invention is to increase productivity.

Поставленна цель достигаетс тем, что горизонтальные оси рычагов снабжены дополнительными рычагами и расположены перпендикул рно выходному валу, причем основные рычаги св заны с муфтой посредством т г, один конец каждой из которых соединен с муфтой, а другой шарнирно - с дополнительным рычагом, при этом свободные концы рычагов выполнены изогнутыми в сторону их вращени .The goal is achieved by the fact that the horizontal axes of the levers are provided with additional levers and are located perpendicular to the output shaft, the main levers being connected to the coupling by means of t g, one end of each of which is connected to the coupling, and the other is hinged to the additional lever. the ends of the levers are curved in the direction of their rotation.

На фиг. 1 изображен корчеватель пней, FIG. 1 shows stump lifter,

5 вид сзади; на фиг. 2 - разрез А-Ана фиг. 1; на фиг. 3 - сечение Б-Б на фиг. 2 (повернуто ).5 rear view; in fig. 2 - section A-Ana of FIG. one; in fig. 3 is a section BB in FIG. 2 (turned).

Claims

The stump lifter contains a drive 1 for rotation, on the case of which elements 2 and 3 are mounted for connecting a tractor to a mounted device and hydraulic cylinders 4 for turning the cutting member at an adjustable speed. To the output shaft 5 of the actuator 1 is attached additional levers 6 with radially spaced spokes. In the supports arranged in the spokes, the horizontal axes 7 are equipped with levers 8 with a cutting tool 9, which is located in a plane passing through the axis of the shaft 5 and forming with the horizontal axis 7 direct or close to this angle. The front surface of the curvilinear part of the arms is bevelled at an angle to the axis of rotation, and the outer side surface is installed with a positive back angle to the path of movement. The inner ends of the horizontal axes 7 are connected by means of the rigs 10 to a coupling 11 that is movable along the shaft 5 and connected to the hydraulic cylinders 4. The ribs 10 have an adjustable length for setting the cutting tools 9 to the same position. The device works as follows. The device with the levers 8 raised to the initial position orients the center of the mon, lowered and fixed at a set height by shifting the control valve spool to the neutral position. The drives are turned on for turning and for turning. The cutting tools 9, rotating together with the shaft 5 and turning together with the axle 7, remove the chips from the wood and soil and form a spherical cut. At the end of the cutting, the arms grab the stump and result in rotation, due to which it is partially cleaned of the soil. The carved stump is lifted from the we and unloaded into the vehicle. The use of the proposed device allows to reduce energy consumption for cutting and chip removal and creates the opportunity to increase the number of cutting tools and improve the working conditions of the staff. Claims of the invention of a stump lifter comprising a frame, a cutting body in the form of curved levers mounted on horizontal axes with knives, a drive of rotation of the levers with a vertical output shaft on which a coupling is kinematically connected to the levers, characterized in that, in order to increase productivity, the horizontal axes of the levers are provided with additional levers and are arranged perpendicular to the output shaft, the main levers being connected to the coupling by means of t, one end of each of which is connected to the mu the one and the other articulated - with an additional lever, with the free ends of the levers are curved in the direction of their rotation.
