Description

The invention relates to mechanisms for handling felled trees and can be used in the logging industry. Known machine for pruning boughs, containing a self-propelled chassis, boot device, a support with a tracked dragging device and a delimbing mechanism 1. However, during operation of this machine, it is impossible to sort the whips during the process of clearing the trees from the branches. This hinders the use of group cutting of logs in lower warehouses and, consequently, reduces the performance of the chewing and sorting streams, while increasing the energy intensity of the sorting process of the assortments. The known machine for cutting branches from fallen trees, containing a self-propelled chassis, on the frame of which a loading device is installed, and on a support - a tracked dragging device and a beam with a delimbing mechanism and support rollers 2. The disadvantages of this machine are low productivity and high energy costs for processing trees. The purpose of the invention is to increase productivity and reduce energy consumption. This goal is achieved by the fact that the machine for clearing trees from branches, containing a self-propelled chassis, on the frame of which a loading device is installed, and on a support - a tracked dragging device and a beam with a delimbing mechanism and support rollers, equipped with an additional rotary in vertical and horizontal mounted on a support planes with a beam, which have lever-mounted ejector arms that are hinged at it with their ends and rigidly fixed at its end to limit the movement of the treated tree, the support rollers are mounted on an additional beam. FIG. 1 shows a tree for de-limbing trees; in fig. 2 is a view A of FIG. one; in fig. 3 is a section BB in FIG. 2; in fig. 4 is a view of B in FIG. one; in fig. 5 - scheme of the machine. The machine for de-knitting trees contains a self-propelled chassis 1 on which a hydraulic manipulator 2 is installed to load trees into a pulling device, a lower bearing 3 pivot in the horizontal plane, a support 4 vertical pivot in the vertical plane, the lower support is rotated by a hydraulic cylinder 5 to install beams 6 and 7 to the transport position, the upper cylinder 8, to ensure parallelism of the axes of the beam 6 and the treated wood. On the upper support 4 is installed lower 9 and upper 10 caterpillars pulling device. The locking head 11 is installed at the end of the beam 6. The hydraulic cylinders 12 and 13 rotate in the horizontal and vertical planes of the beam 7 pivotally mounted on the upper support 4. The rod of the hydraulic cylinder 13 is connected to the beam 7 by means of a rope 14. On the beam 7, the rollers are attached 15 using brackets 16, a dropper 17, as well as a limiter 18 to move the wood to be processed. The drive of the resetter 17 is carried out using hydraulic cylinders 19. The machine operates as follows. The machine is installed on the ground to the piled up tree stack 20. The machine should stand in such a position that the head 11 should be located after the twist of beam 6 on the border of the knot and knot-free zones of the trees. The komel of tree 20 is captured by a hydraulic manipulator and loaded into a tracked dragging device. In this case, the Tree axis should be parallel to the axis of beams 6 and 7. The parallelism of the axes is achieved by turning the upper 4 and lower 3 supports by means of hydraulic cylinders 8 and 5 respectively. The upper caterpillar is pressed against a tree trunk, the knives of the delimbing head 11 are closed on the tree trunk. The tree is pulled by a pulling device through the knives of the delimbing head. When cleaning from the branches of the trees, the first sorting component 21 (the throwers 17 are in the position shown in Fig. 3 by dashed lines) the whips are dropped to the ground after pulling them through the knives of the delimbing head. When clearing the branches of the second sorter component, 22 (the ejectors 17 are in the position shown in Fig. 3 with solid lines) beam 7 is parallel to the tree trunk, and the whip is dropped onto the rollers 15. When the hydraulic cylinder 13 extends, the beam rotates relative to the upper support until the limiter 18 moves the tree to the ground. The whip under its own weight moves along the rollers as on an inclined plane until the butt contacts the stopper. Then the whip of the second sorting component is dropped to the ground by the dumpers 17. . When unloading the whip on the rollers 15 and dropping it to the ground, the hydraulic cylinders 12 and 13 are included in the floating position. This makes it possible to combine cutting operations with the orientation of the beam 6 for placing the next tree through the delimbing head. After resetting the whip of the second component to the ground, the beam 7 is set to its original position. Technical and economic efficiency of the invention is to reduce costs.

There is an additional drag of the second component of sorting, an increasing mechanism for processing trees with handling and unloading of flora. By combining operations, the productivity of the maschine is measured.
