Abstract

The invention relates to forestry machines and can be used for pruning branches from trees and palletizing treated tree trunks on a broomstick. The purpose of the invention is to expand the technological capabilities of the machine when skidding logs in a semi-submerged state. The machine contains a base tractor 1, on which a manipulator 2 with a gripper 3 is mounted, a frame 4 pivoting in a horizontal plane with a storage device 5 mounted on it with a stand

Description

MI 6 and 7, Axis of rotation of the frame 4 and the cumulative device 5 overshift {s. Cumulative device 5 relative to the frame 4 has the ability to rotate. Frame 4 is equipped with a stand 8 with a frame on which the 1SPU locking device is fixed), the SPU contains side swivel levers 16, 17 with knives 18 and the lower unattached knife 15. After laying the tree by gripping 3 manipulators 2 into the SPU, the tree is pulled through The folded knives and the knot-free knives fall into the storage device 5. During the processing of subsequent trees, for which the chassis is turned relative to the axis of the portage, the storage device with previously processed trees remains intact. 3 il.

The invention relates to forestry machines and can be used for pruning tree branches and palletizing treated tree bark.

The purpose of the invention is to increase the productivity of the machine and expand its technological capabilities, as well as simplify the design.

Figure 1 shows the machine, a view in plan; Figure 2 shows the delimbing-nodding mechanism and storage device, side view; fig.Z technological scheme of work.

The machine contains a base tractor 1, a pivoting arm 2 mounted on it with a grip 3, a frame 4 pivoting in a horizontal plane with a storage device 1M 5 installed on it with uprights 6 and 7. The pivot axes of frame 4 and piling device 5 are aligned, while the cumulative device 5 relative to the frame 4 has the ability to rotate within 15-2C ° C. The angle of rotation is limited by a damping stop mounted on frame 4 (not shown).

The frame 8 is rigidly fixed to the stand 8, on which the frame 9 is hingedly mounted with the delimbing-pulling device 10 mounted on it, containing the drag rollers 11 mounted on the pivoting levers 12 and 13, and the delimbing head 14. The delimiting head 14 contains rigidly fixed {cutting knife 15 and side swivel levers 16 and 17 with knives 18 and 19. Cutting head 14 is provided with a knife for biting the tops 20 (actuators turning the levers 12 and 13, side levers 16

and 17, the knife 20, as well as the drives for the drive rollers 11 are not shown).

The swivel frame 4 is provided with a drive for turning it, for example, in the hydraulic cylinder 21, and the frame 9 - in the form of a hydraulic cylinder 22 -.

The machine works as follows

The machine, moving along the fiber, pulls up to the side of the first untreated pile of trees laid (for example, with the LP-19 felling machine) on the portage. The machine makes a turn away from the pack, and the longitudinal axis of the delimbing-pulling device 10 and the accumulation device 5 is aligned with the axle of the die using the hydraulic cylinder 21. The manipulator tor 2, the gripper 3, takes the tree behind the butt and places it in the divorced delimbing protrusion device .10. Racks 6 and 7 of cumulative device 5 are also divorced.

With the inclusion of the convergence drives of the levers I2 and 13 with the traction rollers 11, the drive of the traction rollers and the levers 16 and 17 of the knot-cut head 14, the process of pulling the branches is started.

Before the end of the pulling, the knife drive 20, cutting its top, is turned on. With the apex cut, the traction rollers 1I are diluted and disconnected, and the treated stem of the apical part falls into the storage device 5.

During the dragging of the first tree, the manipulator 2 captures the next tree and, after processing the previous tree, puts it into. the opened delimbing device 10, and the cycle is repeated.

Claims (1)

When processing the 5th pack bundles, the possible misalignment of the next tree with the delimbing-pulling device is eliminated due to a slight rotation of the frame 4 by means of a hydrocyliidra 21. The position of the storage device with the treated trees relative to the chassis frame remains unchanged, since it is installed with the possibility of rotation frame 4 in the horizontal plane. After processing the bundles and pinching the treated trees in the storage device, the machine moves further (the machine is coaxial with the fiber and with the axis of the processed bundle). In this case, the hydraulic cylinder 21 is switched off and is in a floating position. The hydraulic cylinder 22 allows the frame 9 to be installed in accordance with the position of the tree. Moving further along the fiber, the machine goes to the next pack, is placed in the above specified position, with this, when the base rotates relative to the axis of the portage, the hydraulic cylinder 21 is disconnected, i.e. the axis of the delimbing-pulling mechanism and the axis of the storage device, as well as the axis of the treated group of trees, automatically retain their coaxial position with the fiber. After dialing the full carriage, the machine moves to the final point where it unloads the storage device. The machine allows you to concentrate cut boughs and tops directly on the portage. When equipping the manipulator with a gripping-cutting device, the machine can also be used as a shredder. Formula of the invention Logging machine, so--. holding a self-propelled chassis on which technological equipment is mounted, including a manipulator mounted horizontally and vertically, the delimbing-pulling and storage device, which, in order to expand the technological capabilities of the machine when hauling logs in a semi-submerged state, The delimbing and dragging devices are mounted separately with the possibility of independent rotation in the horizontal plane, and their axes of rotation are dreams.
