SU497136A1 - Bunker type installation to remove branches from a pack of trees - Google Patents

Description

This invention relates to forestry equipment.

Bunker tin installations are known for removing branches from a bundle of trees, including the base, traction chains with stops, side walls with chisels, and drive.

The disadvantage of such installations is the low quality of the removal of the branches from the trees, which is due to the rigidity of their side walls.

In order to eliminate this drawback in the proposed installation, the traction chains with unors are stored in blocks installed on the base posts with the formation of a U-shaped container, and the side walls with incisors are made in the form of separate sections hinged between each other and located between the traction chains The top of which is in each shield is hinged on the vertical stand of the base of the installation, and the bottom is connected to the drive of an autonomous shield for the treated pack of trees.

The drawing shows schematically the proposed bunker-type plant for removing branches from a bundle of trees, side view.

The installation includes: a base 1, on which vertical supports 2 are fixed, traction chains 3 with stops 4, stored in leading 5 and supporting 6 blocks (asterisks); side walls, made in the form of shields 7,

each of the sections of shields 7 is provided with incisors 9 and the top of them is connected to the vertical upright 2 by means of the hinge 10, and the lower section is connected to the drive 11 of the autonomous shield 7 to the treated pack of trees. The movement of the traction chains 3 is carried out by means of a drive 12, and a conveyor 13 is provided for removing the branches cut from the trees.

The installation works as follows. A stack of trees with a crown is loaded on

the traction chains 3, the envelopes of the leading 5 and the supporting 6 blocks (sprockets) and forming a U-shaped capacitance between two rows of vertical pillars 2. When the drive 12 is turned on, the leading blocks (sprockets) 5 set in motion the traction chains 3 with stops 4 which begin to rotate a pack of trees and individual trees in a pack above the base 1. As a result of the contact of the lateral surfaces of the rotating trees with each other, with the traction chains 3 and the incisors of 9 shields 7, the branches break off and are cut off, after which they are carried away by the conveyor 13. Degree clamping incisors 9 to the side surface rhnosti bundle of trees and the number of entered into contact with the trees in E

shields 7 and their sections are remotely controlled by the operator using drives 11, depending on the size of the knotted zone of the trees, the strength of the branches and the season of work.

Treated tree trunks are discharged from the plant into the transverse slit for further processing using one of the known methods, for example, by selecting the draw chains 3.

Subject invention

Installation of bunker type for removing branches from a pack of trees, including the base, traction chains with stops, side walls

with cutters and a drive, characterized in that, in order to improve the quality of tree branches removal, traction chains with stops are stored in blocks installed on the base posts to form a U-shaped container, and the side walls with cutters are made in the form of shields from separate pivotally interconnected and located between the traction chains of sections, the upper of which

in each shield, it is pivotally fixed on the vertical stand of the base of the installation, and the bottom one is connected to the drive of autonomous pressing of the shield to the treated pack of trees.
