Description

The invention relates to devices for removing branches and tops from a group of trees 11 intended for use in a forestry industry.

An open-type installation for group processing of trees is known, including inclined flexible traction bodies with abutments located iodine angle to the longitudinal axis of the plant, side shield with knives, and spring-mounted gland cutters installed in the gaps between the traction bodies, end walls and thrust supports.

The aim of the invention is to provide the possibility of spraying the tree vertices in a bundle during its processing and improving the quality of stem processing. For this purpose, the support struts are made with JAHI-peak eagles, the bottom face of each of which is located at the level of the supporting surfaces of the traction organs. In addition, cutting elements with working edges directed toward the movement of the shafts are installed in the slots-catchers of the tops.

On . 1 inoKasaHa installation, llane; ua flg 2 - TiO, section A-A in FIG. one; in fig. 3 - node B, section 3; NZ FIG. 4-installation diagram of the cutting elements.

The installation contains inclined flexible traction organs, for example, chains / with grippers 2, located: -1e at an angle a to the longitudinal axis

installations and irradiated From electric motors 3, inclined lateral shield 4 with knives 5, spring-loaded pressure cutters 6, end walls 7, thrust supports 8,

supplied in the apex part of the bunker; groove-catcher .m and vertices, as well as cutting elements 9 in the area of the catchers. To move away from the installation of the branches and the apex under the traction mn chains, a tray with inclined planes MI 10 is installed, along the bottom of which the traction bodies move // the harvesting transierterms. The installation works as follows. A bundle of trees in one direction is loaded into a bunker formed by traction chains and a side shield. When the plant is started up, the trees are raised upwards to the supporting posts that prevent further lifting, then roll down DOWN to the side shield under the action of their own weight. As a result

mutual impact, tren.i, as well as the blows of trees against the side shield of a bough break off. When the trunks move upwards on the traction chains and when they are lowered down the side shield, the remains of the branches are trimmed with cutters and knives.

lateral shch.ita. When the tree trunks reach the thrust struts, the top parts of the trunks under the action of the traction bodies enter the trap grooves, approach the cutting elements, cut them. Or break off under

parts of the barrels do not enter the trap manholes and circulate, in the bunker, in the usual order. The cut-offs and tops fall into the tray of the collecting conveyor and are carried outside the installation. As trees are processed, their stones move to the end wall due to the location of the traction bodies at an angle to the longitudinal axis of the installation.

Subject invention
