Description

This invention relates to logging technology and can be used in the forest industry.

The aim of the invention is to increase the productivity with separate bundle harvesting of trees of two different categories in the cutting area.

FIG. 1 shows a possible variant of a feller buncher capable of implementing the proposed method, 1 in FIG. 2, a possible variant of the gripper shearing device of a feller buncher designed to implement the proposed method (tree transfer moment); Fig, 3 shows a general view of the scheme for the development of a cutting area with a single logging mustache; in fig. 4 is the same, with two forest mustache.

The method can be carried out, for example, using the machine shown in FIG. 1 and 2.

On the frame of the self-propelled chassis 1 of this machine is installed a turning platform 2 with the power plant, operator's cabin and technological equipment. Technological equipment includes a manipulator consisting of articulated links 3 and 4, a gripping and cutting device consisting of a body 5 on which are installed with the possibility of rotation by means of drives, for example, hydraulic cylinders 6 and 7, upper 8 and lower O gripping levers and cutting body 10

The case 5 of the shear-cutting device has the ability to rotate relative to the manipulator in two mutually perpendicular planes. One of these possibilities of rotation is realized around the axis 11 in the vertical plane of action of the manipulator, and the second in the perpendicular plane to it (transverse) around the axis 12. In order to realize these possibilities, the link 4 of the manipulator can be connected with the bracket 14 swiveling around the axis 11 by means of the actuator 13, which, in turn, is connected with the housing 5 through the mechanism of rotation. consists of a fixed 15 and a movable 16 parts. The fixed part 15 is rigidly connected to the bracket 14, and

the movable part 16 is rigidly connected to the housing 5. The movable part 16 is able to rotate relative to the fixed part 15 around the axis 12 by means of an actuator, for example a hydraulic cylinder 17, the axis 11 perpendicular to the axis 12.

In addition, in the drawings there are logging mustaches 18, the massif under development 19, the feller buncher 20, the cutting areas and sand 21, the direction of movement (path) 22 of the feller buncher, the stacked packs of trees of one of the categories 23, another category 24.

Examples of the method.

When developing logging areas with a single logging mustache (FIG. 3), machine 20, moving from barbell 18, goes to the first working position and proceeds to picking and laying trees of two categories, for example, coniferous and hardwood, small and large, etc. For each tree, the operator, control 3 and 4 of the manipulator and rotation of the platform 2, directs the gripping-cutting device to the tree. Prepend the upper 8 and lower 9 gripping levers openly press the case 5 of the shear cutter to the tree and clamp it. The cutting body 10 cuts the tree. The operator then transfers the tree to the stacking area. The stacking area is selected for reasons of ease of tree trunking with a bagging machine (it can be used in the absence of a machine with a hooking skidding machine with a rider and manipulator, which has a gripping body).

For this, the komlis of the stacked trees are oriented toward the logging bar 18. It should also be noted that the operator determines the sequence of tree removal at each of the working positions from the condition of the possibility and convenience of subsequent tree laying. In particular, the operator begins picking trees from the far side of the work area of the manipulator, in which the trees are to be laid. Moreover, if the adjacent apiary is not cut (for example, when developing the first apiary, around which there is a forest from all sides except one), the machine can lay down the cut trees when the packs are formed with the tops (crowns) between standing trees.

In the case of the development of the second and subsequent apiaries, as well as the first apiary (if there is a side track), trees are laid with tops (crowns) on the adjacent cut apiary. The trees are laid at an angle to the path 22 of the movement of the machine 20. Angle

chosen for reasons of ease of installation without adhesion between packs (or with minimal adhesion) and the convenience of subsequent skidding of some packs without destroying others. At each working position, machine 20 places trees of different categories into two formed packs of trees, the machine puts trees into one of them one category perpendicular to the plane of the action of the manipulator, raalizu turn of the gripping device around the axis 12, and in another tree of the other category parallel to the plane of action of the manipulator, the real iu turn

5 gripping and cutting device relative to axis 11. Moreover, at each subsequent working position, the machine places the trees of one of the categories in a pack of trees of the same category, the formation of which

0 started by this machine in the previous working position. Thus, it turns out that each pair of contiguous working positions has one common bundle for one of the tree categories for them, Despite

5 the fact that at each working position the trees are stacked in two different packs, the number of final packs corresponds to the number of working positions. The volume of each of them approximately corresponds to the volume of one pack,

0 by the forming machine for packing in the usual way from one working position when laying all the cut trees at this working position in one pack. Therefore, the performance

5 of the skidding machine after such laying will not be lower than when skidding packs formed by a feller buncher in the usual way from trees of different categories,

0 When working in the cutting area with one mustache, the machine after the development of the next apiary moves to another and begins its development from the opposite end to the previous apiary. When moving

5 the machine also puts the packs at an angle to its path, but in the direction of the usa of the forest road,

When skidding packs of trees into two whiskers, packs in apiaries are placed in buttresses.
