The invention relates to the harvesting of wood from trees in ripe birch, and aspen forests and other mixed stands, and processing trees and harvesting the timber handled by existing types of domestic felling-bunching machines, equipped with replaceable compact pick-cutting devices modular fabrication with specified maximum weight and load capacity installed at the end of the manipulator with a large departure (flight of the working body not less than 12.5 m horizontally and 18 m in the vertical plane).

There is a method of procurement assortments manipulator machine using typical gripping-cutting device (see the book: Anisimov S.E., Misurkin PM Multilink manipulators. - Yoshkar-Ola: Marstu, 2003. - 76 C.). This method includes steps: first, cut kroon part and put (or reset) in one pack on the back of the trench, and then cut the logs consistently on the principle of "top-down" from the apical part of the standing trunk to his butt.

The disadvantage of multi-processing is. that way is difficult when processing a single tree, and it is not possible to increase the yield of valuable assortments.

There is also known a method of processing trees and harvesting the timber Feller-PA is etorousa machine (U.S. Pat. 2250599 Russian Federation, IPC7A01G 23/02, 23/08, 213/081, 23/083, the authors Misurkin M., Anisimov S.E., Besides IGOR Vladimirov, A.A., Ivanova NS (RF)), including the removal of the kroon part of a growing tree and leaving the trunk for a few months for the natural drying of wood, and then cutting the timber down the barrel to his butt gripping-cutting device felling-bunching machine.

The disadvantage is that the serial sectioning of assortments from the vertex part of the standing trunk to his butt out only three types of unmeasured assortments (apical, mid and butt logs). If this is not taken into account the need for valuable assortments of different sizes with tolerances in length. Off-gauge metal is not allowed to receive further dimensional cut-to-length with high precision, as this will lead to large losses of wood. Therefore, the prototype is only applicable to the low quality of the stands. And in maturing and Mature birch economically provide a hierarchy of types of assortments decrementing values.

The technical result is an increase in the yield of valuable assortments, such as plywood ridge when the workpiece dimensional assortment in maturing or Mature birch.

This technical result is achieved in that the method of harvesting the timber and working op the Academy of Sciences of the machine for its implementation, includes first cutting of the branches of the tree from the bottom up, and then cutting the timber down the barrel to his butt gripping-cutting device felling-bunching machine, characterized in that the gripping-cutting device is induced on the barrel with the laying of its emphasis on the end of the stem, then it goes down with dimension of length, after the measurement is captured by the barrel and cut the line, then the procurement cycle assortments again to a lowering of the working body on the ground, at the end of the cycle is cut butt unmeasured assortment.

Emphasis is placed on the end of the stem, and it stays on it when moving the gripping-cutting device down, the measurement length is happening until it engages the stop.

Measurement of birch or aspen assortment to business trunks perform on the length of the valuable timber, such as plywood ridge length of 1.3 or 1.6 m, and the length of these two sizes perform as required for domestic shelling machines, wood hills, and on the trunks with the other plots measuring wood ridge perform in a length of one meter, and the other of the shafts is prepared only wood assortments.

When processing of the barrel with a thin apical part is additionally measured with the aid of grippers gripping-cutting device, the diameter of the barrel near the place cf the marks, if the diameter is less than 16 cm, length measurement range perform up to one meter.

On the top of the rack cover will be fitted with a hole, which houses a movable stand with a clamp at its lower end, and the lock is located inside the rack can move to cover, on the upper end of the movable rack is made of two pairs of holes for fastening, such as bolts, split lock, and on the sides of the movable rack two labels applied through 300 mm for measuring the length of a wood-burning range in one meter.

The essence of the method lies in the fact that when harvesting wood gripping-cutting device Feller-buncher to go from standing trunk of business (quality) trees consistently top-down dimensional cut down the logs and trunks with with other sites in addition to measuring the timber cut down wood ranges in length in one or the other (less than the length of the valuable timber, plywood ridge 1.3 or 1.6 m) meter.

The essence is that the working body fit with emphasis on the end of the stem that acts as a rigid support for the work of the authority and even the pointing device when sawing the barrel across to procure the assortment with the exact length. Therefore, the length measurement sawn off assortment comes to a complete lifting of the movable rack inside a hundred is key to the hold-down clamp to the stand cover and this increases the accuracy of the measurement length. Moreover, high measurement accuracy is ensured regardless of the sharp fluctuations of the manipulator and the hydraulic system of the machine, and the operator only has to lower the gripping-cutting device until the full length of the cut away assortment, that is, until full contact retainer movable rack rack with cover.

The essence of the design authority felling-bunching machine is that the gripping-cutting device is designed modularly with existing machine type PL-19C and movable stand, made from afar with prominent labels and stop laying the tool on the end of the stem, performs useful essential technical features measuring different lengths valuable or wood assortment. Movable stand with labels and adjustable stop gripping-cutting devices allow harvest dimensional and non-standard cut-to-length from a single trunk.

However, depending on the position of the stop on the movable rack provides for the possibility of harvesting of valuable assortments in the form of plywood ridge two sizes of 1.3 or 1.6 m in Addition, adjusting labels travel of the movable rack, you can cut logs with a length of about 1 m For one machine can produce a set of gripping-cutting organs for harvesting wood and other lengths, and length up to 6.5 m

ovesna technical solution is the existing felling-bunching machine is equipped with modular gripping-cutting device with mobile stand and extreme position about the end of the stem, which also marks, and emphasis about the end of the stem is made removable and interchangeable hole on the upper end of the movable rack. The focus is fixed with plug connection and therefore it is possible to apply a set of movable racks and removable stops for laying the tool on the end of the stem.

The positive effect is that the use of a gripping-cutting device with mobile stand and extreme position allows you to gain valuable assortments of the same length, equal to the move mobile rack 1.3 m or 1.6 m with low tolerance. For example, when the workpiece plywood ridge precision cutting is such that the error length is less than the tolerance according to GOST 2...5 see, This allows to increase the output of valuable assortments and reduce wood loss when harvesting wood from trees of different product quality.

The positive effect is also that the proposed method and the working body for its implementation allow selective felling given to foresters trees in the forest care. At the same time the leave on the growing trees are not damaged due to the fact that the logs are processed directly on the trunk.

On ogically effect is also that this same machine with replaceable standard capture-cutting device, equipped with a delimbing head, first perform the cutting of the lower boughs and branches of a growing tree, and then cut kroon part of the tree, leaving the stem end at the top. After processing all led to the felling of trees on the machine change the gripping-cutting device on the proposed working body, which make the assortment of different length in the form of plywood ridge with the exact length and firewood is approximate length with vertically arranged shafts.

The combination of functional and structural distinguishing features has a significant novelty and has a positive effect, and ease of implementation in forest enterprises.

In the scientific and patent literature materials prejudicial to the novelty of technical solutions was not found.

FIELD: forestry.

SUBSTANCE: method involves cutting light stocking and bunching bundles; skidding said bundles onto floating base by means of cable, with bush cutter continuously moving and upper pulley being mounted on bush cutter and winch being positioned on floating base. Cutting and bunching procedures are provided while floating base continuously moves.

EFFECT: improved quality of cleaning of basin beds, increased efficiency and reduced expenses for performing such works.

FIELD: forestry, in particular, processing of individual trees, may be used for cleaning cutting in average aged and ripening stand.

SUBSTANCE: method involves processing tree by initially cutting branches from the bottom to the top of tree over trunk up to crown part; upon removal of crown part, leaving trunk for several months to provide for natural drying of tree trunk. Method allows versatility of felling-bunching machine with gripping-and-cutting boom to be increased and operational capabilities of machine to be widened owing to adaptation to different kinds of tree and stand care processes. It means that single machine may be used for tree clear or selection felling processes, as well as for caring of crown of individual trees. Method may be effectively used for caring of trees in parks, gardens and preservation plots by means of existing felling-bundling machines furnished with small-sized gripping-cutting booms having maximal predetermined weight and load capacity.

EFFECT: increased efficiency and wider operational capabilities.

FIELD: forestry, in particular, clearing of green felled area for forest crops.

SUBSTANCE: method involves dividing felled area into strips to be cleared and spaces between strips not to be subjected to clearing; gathering felling residue by means of brush rake movable on cleared strips and shifting felling residue onto spaces between strips by alternatively turning to the right and to the left to thereby form felling residue piles; after clearing strips on the entire felling area, burning felling residue; grubbing out stumps from cleared strips by means of grubber-collector, which moves grubbed stumps to felling residue burnt piles; leaving the latter for decaying.

EFFECT: reduced sizes of felling residue piles and increased area of spaces between strips for natural regeneration stands.
