SU500059A1 - Device for cutting branches from a pack of trees - Google Patents

Description

The invention relates to a device for cleaning trees from branches in a bundle and can be used in the forest industry,

Known devices for cutting branches from a pack of trees pulled through a cutting circuit include a base with lower power cutting knives, a swivel beam supporting the upper knives of a power cutting sh and a longitudinal supporting axis mounted on it, on which the knives are divided and the cable-blocking system for moving the latter are complex with

The goal of implementation is to build a construction site. nli and increase reliability.

For this, the knives-separators of the device are mounted on the supporting axis of the rotary blade by means of figured openings ensuring the knives are rotated in a plane perpendicular to the tree pulling direction, all the divider dividers are interconnected by intermediate flexings and the outermost ones are made with an elongated seating base along cylindrical

surfaces, and the supporting axis is installed in the supports of the swivel beam with a gap, which during operation ensures the interaction of the back sides of the separator knives with the support surfaces of the beam and the base of the device.

FIG. 1 shows a device for cutting branches from a bundle of trees, top view; in fig. 2 - a section of the closed knife contour, side view; in fig. 3 and 4 - figured hole in the separating knife.

The device for cutting branches from a bundle of trees consists of a base 1 with lower blades 2 power cutting and a swing beam 3 carrying the upper blades 4 power cutting fixed on the base 1 by means of a hinge 5. In the lower operating position the swing beam 3 is fixed in the slot 6 base 1. On the rotary beam 3 with a gap in the supports there is a longitudinal supporting axis 7 on which the knives are mounted by means of hinges mounted with figured holes 8.
