Zusammenfassung: | FIELD: forestry.SUBSTANCE: invention relates to the field of logging. Separating load-gripping mechanism (SLGM) of the descending type of movement of the conical form is held by the balloon during the descent by means of four side winches and is divided into two working units for processing a vertically standing tree. Upper unit is designed to hold the top of the tree during its cutting and transfer to the unloading station and is made in the form of a power ring with extendable toothed paws. Lower unit is made in the form of a truncated cone, inside of which there is a system for holding the butt section of the barrel and an inertial cutting mechanism. Moreover, the cutting of branches occurs due to the inertial cutting mechanism from the complex of different-level knives fixed on the edges of the inner part of the clamping lobes. Petals, due to the torsion springs fixed between them and inside the working cone, ensure that the blades fit tightly against the trunk of the tree. Clamping lobes with knives are located on two levels vertically. SLGM has a system of retention of the vertex and the stump parts of the tree trunk, represented by worm electric mechanisms designed to extend the toothed paws. Process of lowering, guidance and lifting of the SLGM is carried out by means of four cargo electric cables designed to hold the upper and lower parts of the SLGM and transfer electric energy from the generator of the guidance mechanism to the worm mechanisms of the tree trunk retention system.EFFECT: invention makes it possible to improve the air way of forest skidding, to ensure the safety of the process.4 cl, 4 dwg
Изобретение относится к заготовке леса. Разделяющийся грузозахватный механизм нисходящего типа движения конусного вида удерживается аэростатом в процессе опускания с помощью четырех бортовых лебедок и для обработки вертикально стоящего дерева разделяется на два рабочих узла. Верхний узел предназначен для удержания верхушки дерева в процессе его спила и переноса в пункт разгрузки и выполнен в виде силового кольца с выдвижными зубчатыми лапами. Нижний узел выполнен в виде усеченного конуса, внутри которого расположены система удержания комлевой части ствола и инерционный режущий механизм. Причем срезание ветвей и сучьев происходит за счет инерционного режущего механизма из комплекса разноуровневых ножей, закрепленных на краях внутренней части прижимных лепестков. Лепестки за счет закрепленных между ними и внутренней частью рабочего конуса пружин кру |
