Description

The invention relates to the forest industry and can be used in the complex mechanization of logging operations. A forest logging company is known, which contains a self-propelled chassis on which a boom is mounted with an articulated boom with a frame with a cutting mechanism and a gripping body swiveling around its horizontal axis. The gripping body is made in the form of two grippers that are hingedly mounted on the frame by means of double triangular links with the possibility of nepe displacement along the radius curve in the transverse direction of the frame, with the central axes of the grips and the cutting mechanism parallel to each other 11. Also known is a logging machine for group processing of trees, which contains a self-propelled chassis on which a cutting-cutting device having a slewing drive and is mounted. transversal movement, and with the help of brackets rotatable in the vertical plane of the frame, having telescopic longitudinal rods, one end of which is connected to the transverse beam on which the delimbing device is mounted, and drives C2. A disadvantage of the known logging machines is a large metal intensity due to the complex construction of these machines. The purpose of the invention is to reduce the metal capacity and simplify the design. This goal is achieved by the fact that at the logging maple tree for group processing of trees containing a self-propelled chassis on which a gripping-cutting device with a drive for turning and forward movement is mounted, and with the help of brackets, the frame with telescopic longitudinal shafts are rotatable in the vertical plane and have telescopic longitudinal bars, one the end is connected to the crossbeam, on which the delimbing device is mounted, and the drives, the gripping-shearing device with the rotation and lateral movement drives mounted on the other end of the longitudinal shtang and equipped with a storage of cut trees. The drawing shows the proposed machine, a general view. On a self-propelled chassis 1 of a tree harvesting machine for group processing of trees, the frame 3 is mounted on brackets 2 in the vertical plane, having telescopic longitudinal rods 4 connected by transverse beams 5 and 6. On beam 6 of frame 3, a delimbing device 7 for group processing is mounted. levers 8 and articulated on beam 6 and levers 8 spring-loaded delimbing knives 9; The pivots 8 are rotated relative to the beam 6 by means of hydraulic cylinders 10. The frame 3 is rotated (raised and lowered) by the hydraulic cylinders 11, connecting the self-propelled chassis 1 with the beam 5. The gripping-cutting device 12 (ZSU) to the accumulator of cut trees 13 has turning drives 14 and lateral movement (not shown) along the turning guide 15. The gripping-cutting device 12 consists of a cutting member 16 and hydraulic grips: right 17 and left 18. ZSU 1.2 with a storage of cut trees 13 and turning drives 14 and lateral movement a rotary guide 15 is mounted on telescopic longitudinal rods 4 of frame 3. The timber planter works as follows. Driving along the cutting area, the self-propelled chassis 1 stops in front of the tree to be cut. Then, the ZSU 12, by pushing the frames 3 and the telescopic longitudinal rods 4, moving along the pivoting guide 15, is led to the tree of one of the sections of the accumulator of cut trees 13 with the subsequent clamping of the tree with hydraulic grippers. The cutter 16 is cut down and remains squeezed. Then the ZSU 12 is guided to the next tree by another section of the accumulator of cut trees 13. If the tree stands aside, the machine moves to it with the tree clamped in the ZSU 12, the operation is repeated, and the second tree is clamped into a free section. After filling the section of the accumulator of cut trees 13, the ZSU 12 lifts the frame 3 with the help of hydraulic stubs 11, and by turning the ZSU 12 to the rotary guide 15 using the hydraulic cylinders of the rotation drive 14, place the trees on the transverse beam 6 of the trimmer 7 without unclamping the grippers of the ZSU. The tree trunks are then covered and held by levers 8,

After that, the machine treelit trees to the place of packing or storing. When skidding trees, clamped ZSU, can move along the beam

6rams 3 using telescopic longitudinal rods 4 to evenly distribute the masses on the chassis.

After the machine stops, the trees are covered in a delimbing device.

7 with the help of 8 spring-loaded knives, pivotally mounted on the beam 6 and side levers 9. Extend telescopic longitudinal bars 4 with the help of mounted

in these, the hydraulic cylinders, the trees, are pulled through the delimbing device 7, pruning the branches.

After the advancement of ZSun, the entire course of the hydraulic cylinders, the seizures of the latter are opened, the ZSU returns to its original position, and the trees are again clamped by the seizures. These operations are repeated until the branches are completely trimmed.

Upon completion of pruning and unloading the logs onto the ground, the machine is sent for a new packet of trees. If necessary, a logging machine for batch processing of trees can produce the cutting of tree trunks cleared of twigs.

Thus, the use of the proposed design of a forest machine for group processing of trees makes it possible to reduce the metal consumption and increase reliability by simplifying the design of the forest machine.
