Description

The subject of the invention is the construction of a self-propelled logging conveyor, in which, in order to increase the efficiency of wood harvesting, a combination of using electric saws for felling trees, a mechanism for cleaning branches, a balancing circular saw for cutting logs and a logging device is provided.

The proposed conveyor is a moving working site on a track with a balance suspension, on which the main conveyor is located in the longitudinal direction.

The drawing shows a logging conveyor.

In the front part of the conveyor, a metal arch is installed. Through the guide rollers 2 of the arch head, two skidders 3 are pulled, which are wound on the drums 4 of the mechanical winch.

Under the arch / located the first section of the main conveyor 5 with toothed hooks.

The second section 6 of the main conveyor is 4.5 meters from the first one and has a guide cone 7. Circular saws with a feed chain conveyor are used to crush the branches. Between the first and second sections of the main conveyor there is a receiver 8 for chopped off branches with drums 9, on which a pinch is located on a cylindrical surface. Under the drums 9 passes the belt conveyor 10 for crushed branches. An elevator II feeds a bough into a bunker 12 for heating a vertical steam boiler 13.

The steam engine M, the turbo-generator 15 and the steam-air pump 16 with the receiver 17 are mounted in the central part of the conveyor.

The forward movement of the conveyor is carried out by the leading tracks 18.

about

. "In the front of the conveyor there is a retractable barrel roller 19 with a flange. The whips supplied by the conveyor 21 are trimmed for a long distance with a balancing saw 20. A metal retractable platform 22 equipped with a toothed rack, rolling 23 and pushers 24 are intended for stacking the bag. The electric saws are powered by the current from the turbo generator 15. The conveyor operates as follows. At the beginning of the conveyor passes through the edge of the forest. Two electric saws, serviced by five workers, made a roll in a 3-wide strip. Felling the forest goes from the edge of the site to a clean place, parallel to the course. When the roll ends on the first strip 2,000 meters long and 3 meters wide, the conveyor turns 180 °, enters this strip and starts processing the whips in front of it. The working width of 3 m corresponds to the width of the fallen strip. Electric saws, following the conveyor at a distance of up to 30 m, are made to fall on an adjacent strip 3 m wide. This order work | persists in the future. Passing a strip of 2000 m in length, the conveyor turns around and goes in the opposite direction along the adjacent strip, where the heave is prepared. At this time, the next lane collapses, etc. The felled trees in all cases are placed in the front of the conveyor. From the minimum distance, the next whip hooked by the hook of the skimming cable is pulled out under the arch and, being released from the hook, falls on the sleepers of the main conveyor belt. The underflooding is serviced by four workers, of whom two throw self-gripping hooks onto the whips, and two control the undershoot winches. A whip passing through a delimbed ring enters the main conveyor. The chopped off branches fall into the receiver, are pulled into the crusher and, crushed, fall onto the conveyor belt located under the drums and then through the elevator into the bunker. The branchless trunk is advanced into the distribution area of the bag. When the whip is advanced to the length of the harvested length, the conveyor main conveyor stops, and the balance saw produces cutting. During the cutting, the sacks (two workers), having determined in which of the two packages the sawn log should be laid, push it into the required size using a simple “rolling” mechanism. A sawn log "pushers collides with the platform and along" slopes with a slope from the middle, rolls down into a bag. At this time, the conveyor feed is turned on for the next cut. The two packages are 0.4 m apart. The capacity of the two packages is 25 m and is designed for laying cut wood collected from a strip with a length of 330 m and a width of 3 m. Subject of the invention 1. Self-propelled logging conveyor in order to increase the efficiency of harvesting wood, electric saws for felling trees, a branch cleaning mechanism, a balancing circular saw for cutting logs and a logging device. № 78295
