(54) УСТРОЙСТВО ДЛЯ СРЕЗАНИЯ ДЕРЕВЬЕВ(54) DEVICE FOR CUTTING TREES

1one

Изобретение относитс к устройствам дл срезани деревьев и примен етс преимущественно в лесозаготовительной промышленности и лесном хоз йстве.The invention relates to a device for cutting trees and is used primarily in the logging industry and forestry.

Известно устройство дл срезани деревьев , включающее стойку с направл ю- 5 щими, в которых установлен нож силового резани и привод перемещени ножа 1.A device for cutting trees is known, comprising a stand with guides, in which a power cutting knife and a drive for moving the knife 1 are installed.

Недостатком известных устройств вл етс недостаточна возможность направленного повала деревьев при срезании.A disadvantage of the known devices is the inadequate possibility of directional felling of trees when pruning.

Цель изобретени - обеспечение направленного повала деревьев.The purpose of the invention is to provide directional trees.

Дл достижени этой цели устройство снабжено дополнительными направл ющими , нож на своих концах имеет пальцы, 1S расположенные в дополнительных направл ющих , а на стойке установлен упор дл поджати деревьев навстречу рабочему ходу ножа.To achieve this goal, the device is equipped with additional guides, the knife has fingers at its ends, 1S located in the additional guides, and an emphasis is placed on the stand to press the trees against the knife's movement.

На фиг. 1 изображено устройство дл о срезани деревьев, общий вид; на фиг. 2 - сечение А-А на фиг. 1; на фиг. 3 - сечение Б-Б на фиг. 1.FIG. 1 shows a device for cutting trees, a general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one.

Устройство дл срезани деревьев состоит из стойки 1, на которой укрепленыThe tree cutter consists of a stand 1, on which are mounted

направл ющие 2, в которых перемещаетс нож 3.guides 2 in which the knife 3 moves.

Claims

The fingers 4 are mounted on both ends of the knife 3, which are inserted into the additional guides 5. The fingers 4 allow the translational and rotational movement of the knife 3. The additional guides 5 are made in the guides

2. As the drive of the knife 3, two hydraulic cylinders 6 are used, the rods of which are connected to the knife 3, and their body is rigidly mounted on rabbits 7 which are attached to the body. On one of the hydraulic cylinders 6, a sliding grip 8 is mounted on the brush, which moves between the plates of the stops 9 and has the ability. open by means of a spring 10 at the exit of the plates of the stops 9 (the position of the sliding grip 8 at the exit of the plates of the stops 9 is shown in Fig. 2 by a dashed line). In addition, the device is provided with a spring-loaded stop 11 with a spring 12 for felling trees, the shafts 13 of which are installed in the guides 14. A tree-cutting device is mounted on the manipulator 15 of the forest machine. The device for cutting trees works as follows. When the logging machine is operating, the device, for example, using the manipulator 15, is guided to the tree to be cut. In this case, the knife 3 is in the position indicated in FIG. 3 dotted line. After that, when the hydraulic cylinders 6 are turned on, the knife 3 with the fingers 4 inserted into it, moving along the additional guides 5 made in the guides 2, begins to turn until the other end of the knife 3 with the finger 4 enters the other additional guide 5. The direction of movement of the knife 3 is indicated by the dotted line in FIG.

3. At this moment, the finger 4 falls into the sliding grip 8, which is fixed after it reaches the stop plate 9. After this, the tree trunk is cut and both hydraulic cylinders 6 are working. the device is pressed against the tree, while the spring-loaded stop 11, moving in the guides 14, compresses the spring 12, and after cutting the tree of compression, the spring provides the spring-loaded stop 11 with a force sufficient for directional falling tree. In the transport position, the knife 3 must be installed in the position indicated in FIG. 3 main line. When aiming at a new tree, the hydraulic cylinders 6 are turned on, and the knife 3, the fingers of which 4 move in additional guides 5, comes to the position indicated in FIG. 3 dotted line. After the sliding grip 8 comes out of the plates of the stops 9, it opens by means of a spring 10 and releases the finger 4 of the knife 3, allowing the knife 3 to move freely. Another additional guide 5. The technical and economic efficiency of the proposed tree-cutting device consists in providing a directional tree felling. Claims A device for cutting trees, including a stand with guides in which a power cutting knife is installed, and a knife movement drive, characterized in that, in order to provide a directional knock down of trees, the device is provided with The ends have fingers located in the additional guides, and an emphasis is placed on the stand to press the trees against the blade travel.
