ΟΊ <l GO trees at maximum reach after sawing up with a hydraulic cylinder 12, a tree with a stand 5 and a slider 7 leans towards the machine. Then, the hydraulic cylinder 4 is turned on and the boom pulls the strut 5 from the slider 7 until then (with clamped grips 6 and 8). until the double link 10 straightens up. At this time, the tree comet is pulled closer to the machine and the large tree is then transferred to the bundle.

The hydraulic lines to the grab 8 and the saw mechanism 9 are fed through a double link 10.

On the basis of LP-19A (5 hydraulic lines) with the help of hydraulic cylinder 11, bucking of a sawn tree is possible. For this, after sawing the tree with the help of the hydraulic cylinder 12 leans towards the machine, and with the help of the hydraulic cylinder 4 and boom 3 rises above the ground. Then, the hydraulic cylinder 11 is turned on for extension and with a weakened grip 6, the tree is pulled forward. According to the marks on the slider 7, the operator notices ko10

The invention can be used in the forest industry as a feller buncher, delimbers, delimbers, and bucking machines.

The purpose of the invention is to increase the stability of the forestry machine when working with large trees,

The drawing shows a forestry machine, a General side view (dotted line shows the position with a minimum reach).

The forestry machine includes a running gear 1, a rotary platform 2, and a hydraulic manipulator consisting of an arrow 3 with a drive 4, a gripping-cutting device comprising a strut 5 on which the upper grab 6. is mounted. On the slider 7 inserted in the strut 5, the lower grab 8 is installed with the saw mechanism 9. The slider 7 is connected to the rack 5 through a two-link me-! Khanism 10 with a drive 11. The gripping-cutting device is controlled by a drive 12.

Logging machine runs extension. Then the grip 6 clamps as follows.

The logging truck drives 25 to the standing trees. The operator directs the boom 3 onto the tree, then lower the lower grab 8 is lowered using the hydraulic mechanism 9 with the help of the hydraulic cylinder 10 to the place of cut, grabs and cuts the wood with a gripping-cutting device. property.

With a maximum boom reach of> 3, the saw mechanism 9 rests on the ground with the two linkage 10 folded. In this case, the hydraulic cylinder 11 is retracted. With a minimum reach, the two linker is stretched.

When used as a support for the surface of the soil, the hydraulic cylinder 11 can be eliminated. This allows the use of commercially available single bucket hydraulic excavators; They have four hydraulic lines for converting them, and the gripper 8 is weakened, and the hydraulic cylinder 11 is retracted until the gripper and saw mechanism 9 are turned on after the length is measured. The sawn assortment falls to the ground and the cycle repeats.

When installing delimbing knives on grab 6, the machine performs the functions of sawing wood, trimming branches and bucking the whip.

The proposed machine is simple in design and allows the use of serial od 'bucket hydraulic excavators.

For even greater simplification, it is proposed to use the boom from the MTPΊ3Α machine in the form of an articulated parallelogram (the two link is located on the side). In this case I, it is possible to use excavators having three or four hydraulic lines.

Thus, the proposed technical solution has versatility for blanking machines (excavators, practical implementation for block-module equipped with a grab). ''

In this case, skis are installed below the sawing mechanism 9, allowing the sliding-cutting device to slide on the ground or in snow. With the lowering of the boom 3 and the rotation of the hydraulic cylinder 12, the half-I zun 7 moves into the rack 5 from the pressure forces of the mechanism 9 on the ground. Grips 6 and 8 are fed to the tree,

When felling large trees, car 1 drives up to them at a close distance! I carry out and carry out felling with a minimum reach of boom 3. In this case, the distance between the grabs 6 and 8 is maximum and the large tree after cutting is well held by the machine. When felling large, the principle of aggregation.

Claims (2)

Claim 1. Forestry machine containing a running gear and a rotary platform with an arrow, a gripping-cutting device with a stand, characterized in that, in order to increase the stability of the machine, the stand of the gripping-cutting device is hollow and provided with a slider inside it, while at the lower end the slider secured the first grip with a saw mechanism, which is connected to the rack by a hinged two-link, and at the upper end of the rack there is a second grip. 1757531 6 2. The machine according to claim 1. This is due to the fact that the articulated double link is located on the side of the operator’s cab under the boom, marks are applied to the slider for cutting lengths to be cut, and delimbing knives are fixed to the second grip.
