Abstract

1. A METHOD of MANUFACTURING FOREST CUTTING WORKS, containing felling of trees on a belt, forming packs of 1- to -9 f by a logging machine, transporting them to a forest usu in order to reduce energy consumption and increase productivity, unloading of packs of packs carried out parallel to the track of the forest usa directly in the cutting area along the belt, with packs of trees formed during the aisle tape them is discharged to the packs of trees grown at the aisles of the previous tapes. 2. The method according to p. 1, different

Description

The invention relates to technologies and techniques for harvesting and can be used in the complex mechanization of logging operations mainly in winter and on soils with high bearing capacity. 5

A known method of producing logging operations, including cutting trees, stacking them with a feller-loading machine on a trailer, which she moves along the cutting area to set up a bundle of the required volume. After this, the loaded trailer is uncoupled and transported by a tractor to the forest road for subsequent transportation by timber trucks, and an empty trailer is attached to the feller-loading machine [1].

The disadvantages of this method are low productivity, high material consumption and energy intensity of the work.

There is also known a method of producing logging operations, including felling trees on a tape, forming bundles of a logging machine with a ₂ θ machine, transporting them to a logging mustache, stacking them, loading timber from stacks onto a logging truck and transporting wood [2].

The disadvantages of this method are the high energy transport you to rabo- ²⁵ Forestry mustache, the time required for cargo and idle machines to wood usu and back and, as a consequence, reduced work productivity.

The purpose of the invention is to reduce energy intensity and increase productivity.

The indicated creep is achieved by the fact that according to the method of logging, which includes felling trees on a tape, forming bundles with a forest machine, transporting them to a forest mustache, stacking them in stacks, loading wood from stacks into timber transport and hauling timber, unloading the collected bundles they are carried out parallel to the path of the logging mustache directly on the cutting area along the belt, and the packs of trees ⁴⁰ formed during passes along subsequent tapes are unloaded to the packs of trees formed when passing through previous tapes.

Logging track whisker deepening in ₄₅ hundred- Ron shortener timber stacks as they are shipped.

The drawing shows a diagram of the development of the cutting area.

The method is as follows. fifty

Logging machine 1 begins the development of cutting area 2, sequentially cutting the trees along the edge of the forest with a narrow ribbon, the width depending on the departure of the manipulator according to a continuous scheme without idling. Cutting trees, the machine puts the butt on the conic. Then it moves to the next parking lot and the cycle of tree set-up for the car continues until a pack is formed with a volume corresponding to the permissible load of the car

Qn = - I ^m *]>

where OL is the volume of the pack in cubic meters;

V - load capacity of the machine, t;

K is the coefficient of distribution of the mass of wood between the machine and the trailer or between the machine and the ground;

Ϊ - wood density, t / m ⁵ . The collected pack of trees is dumped onto the ground directly on the cutting area along the belt parallel to the logging mustache, forming a sequentially continuous stack 3 across the belt, after which, in the direction of travel, they pick up the next stack and dump it into the nearest stack 3, leaving, if necessary, a place for the next passage. The distance between piles is determined by the formula _n

I - Cd where Ch _{p - the} volume of the pack in cubic meters;

from; - forest reserve per ha in cubic meters;

in-width of the developed tape, m. Thus, the entire cutting area is developed.

The forest is loaded from the stacks by a loader 4 onto a timber truck 5. A timber mustache 6 is prepared for stacks by a bulldozer. The preparation of the mustache 6 in the winter consists in clearing the snow and cleaning the high stumps, and in the summer - cleaning the track 7 from felling residues and cleaning the high stumps. As the timber is shipped from the stacks, the track of the logging mustache is deepened in the direction of decreasing the length of the forest stacks. If necessary, carry out the cutting of knots from the trees with a mobile delimbing machine 8, and the whips are stacked in a stack 9. In this way, energy-intensive work — skidding of the forest — is eliminated, while the productivity of the logging machine is increased.

Practical application of the proposed method for the production of logging operations can reduce energy intensity and increase productivity compared to the prototype.

The economic effect per 1 million m ^{5 of} harvested wood is about 163 thousand rubles.
