Description

The invention relates to the processing equipment of closure machines and can be used in forestry, woodworking and forestry.

The purpose of the invention is to increase the efficiency of work through the reduction of energy consumption for cutting vertices.

FIG. 1 shows schematically the capture of a logging machine; in fig. 2 - the same, side view; in fig. 3 shows section A-A in FIG. 1, jaw grip with knives; in fig. 4 shows a section BB in FIG. one; in fig. 5 - a knife; in fig. 6 - work capture on trimming the top; in fig. 7 - the same, on loading wood for butt.

A logging machine includes a housing 1, a power cylinder 2 with a stem 3 and a cross bar 4, jaws 5, hingedly mounted on the cross arm and connected by means of b to the body 1. Knives 7 are mounted on the inner surfaces of the jaws 5, the lower ends of which are matched with internal surfaces of the jaws 5. Equal-sized stops 8 are installed on the cross beam 4 on both sides of the knives 7. Each knife 7 is made in the upper part with an additional face blade 9 perpendicular to the main blade 10. The lower part of the knives 7 has a subdiaux, flooded th edge 11. The length of each additional blade I is equal to or more than half the maximum diameter of the tree being cut and the height h of each block is 8 or painful I. On manipulator lesoza1 otovitelnoy machine capture naveshivaets at 1yumosh, 12 and suspension.

Capture logging works as follows.

To trim the apex, the grip with the open jaws 5 leads to the top of the lying tree. When the jaws 5 are closed, it slides along the inner surfaces of the lower part of the jaws 5 of the grip and the supplying blunt edges of the 11 knives 7. The blunt edges 1 of the knives 7, converging, but not crashing into the apex, help the trunk in the upper part of the throat capture. The barrel of the shaft rises to the stops

8, the jaws are pressed, squeezing, the main blades 10 of the knives are inserted into the wood. 7. The branches and the bough of the tops, which are caught in the upper part of the grip cavity, are clamped on both sides of the stops in the zones formed by the lateral edges of the ugurs 8 and butt end blades 9 (fig. 6), have a snack here when the jaws are closed and do not interfere with the further closing of the jaws 5 with the knives 7 until the apex is completely cut. When loading trees behind the butt into a conic, the proposed gripping device does not damage the stem wood with knives. As a result, the tree is crimped by the lower ends of the jaws 5, the blunt edges 11 of the knives 7 and the stops 8 (Fig. 7).

When trees are loaded with the apical part of the trunk into conic, after cutting the apex, the trunk is captured by the lower part of the grip or the blunt edges of the knives, which allows loading without damaging the tree trunk.

Similarly, several trees can be immediately immersed in the conic at the tip of the vertex after pruning vershinok and packaging on the ground.

Claims (2)

1. Capturing a logging machine, comprising a housing, a ram with a bar on the rod, pivotally mounted and connected by means of jaws with jaws, the inner surfaces of which are provided with knives, characterized in that, in order to reduce energy costs during cutting, the traverse is equipped with two equal sizes lugs located on both sides of the knives, and each knife is provided in the upper part with an additional end blade placed perpendicular to the main blade, which is provided with the inner edge of the knife, and in the lower part is n with a blunt feed. 2. The grip according to claim 1, characterized in that the height of each stop is greater than or equal to the length of the additional blade equal to or greater than half the maximum diameter of the tree in the cutting zone.
