SU1743865A1 - Method of processing trees by manipulator logging machine - Google Patents

Abstract

The essence of the invention: the tree being processed is captured by a gripping-cutting body, pulled in its horizontal position in the direction of the gripping-supporting rotary working body, which is mounted at the opposite end of the boom relative to the gripping-cutting organ installed on it. Cut a branch from a tree trunk and cut it into assortments. Along the boom form the piles of the corresponding lengths of the assortments. When forming the last one in the direction of pulling the pile of assortments, a tree trunk is gripped by a gripping-supporting rotary tool in the area of the front end of this trunk, and after being opened and before laying, the slide is rotated around a vertical axis of the gripping-supporting rotary tool to 180 &;deg; 3 il. w Ё

Description

The invention relates to the forest industry and can be used in the treatment of trees with manipulator-type logging machines.

FIG. 1-3 depicts a logging machine at the time of cutting the branches and frost length of the assortment.

The method is carried out by a logging machine, which consists of a chassis

1 (FIG. 1), in which by means of a column

2, the non-sliding part of the boom is mounted — a guide 3, in which the sliding part of the boom 4 is movably mounted. On the left side of the sliding part of the boom 4, the gripping and cutting tool is fixed 5. On the other hand, the gripping and supporting tool 6 is attached to the sliding part of the boom rotational drive 7. A hydraulic cylinder 8 is mounted on the guide 3, which is connected to a cutting-cutter working body 5. On the guide 3 two levers 9 are rotatably mounted, on which two drive rollers 10 are mounted, which drive is not associated. Not shown and the mechanism of frost length, which, for example, can be mounted in the drive roller 10. The opening is carried out by a chain saw 11. swivel mounted on the guide 3 (its rotation and thrust is not shown).

Position 12 indicates the stack of untreated trees, position 1.3 - the tree to be processed, position 14 - the last pile, position 15 - the near pile of assortments, position 16 - finishes and knots (the latter are not shown).

An example of the method.

The method is most effective when processing piles laid in the cutting area or in the lower warehouse of the river or land.

&

a logging machine, which, as the trees are processed, moves along the tree piles 12, forming a stack of assortments 1) and. 15 (Fig. 1). The operator, by tilting the guide 3 and extending the boom A, leads the gripping-cutting organ 5 to the lying trees 12 and the lateral rotary knives to capture the tree 13 and orient it along the boom. By turning on the hydraulic cylinder 8, the butt of the tree is inserted between the opened rollers 10, which are then reduced to contact with the tree trunk. After that, saw 11 is used for cutting off (not shown) and then the rollers 10 are engaged in pulling the barrel through the closed knives of the gripping-cutting tool 5, as a result of which the length and length of the assortment is cut off. If the assortment is intended for stacking in the middle pile 15, then the operator turns on the saw 13 for cutting and the assortment falls into the pile. If the assortment is intended for stacking in the extreme pile 14, then the operator will first close the jaws of the gripping-supporting working rotary body 6 near the free end of the assortment, and after that it will open. The assortment clamped in the jaw due to the design of the gripping-supporting organ (the structure is not open) while maintaining a position parallel to the sliding part of the boom 4. When activated

drive 7, the assortment will rotate 180 °, after which it will be dropped into pile 14.
