SU923818A1 - Milling working member for aftercutting residual limbs - Google Patents

Description

The invention relates to equipment for additional pruning residues - and can be used in the logging industry.

Known machine for cutting branches from fallen trees, the working body of which is a design of tapered cutter disks forming a cutting contour in the form of a regular Closed variable-section hexagon, and the pressure roller copier is mounted on one movable frame after the upper cutter head in the direction of the log [1 ].

However, the use of a copier-roller of this design in milling heads for additional trimming of residual branches on timber with curvature that freely rotates around its axis does not ensure proper copying, because the copier moves along the cutter along an already machined surface, and when the axis of the rotating timber changes curvature pro2

body for additional trimming of residues of the branches, including coaxially mounted milling head and copier with independent rotation [2].

However, the well-known cutting body is characterized by insufficient copy quality.

The purpose of the invention is to improve the quality of copying when processing large timber.

This goal is achieved by the fact that the copier is installed in one of the supports.

FIG. 1 shows the proposed milling working body, front view; in fig. 2 - milling head with a cam, section.

The milling tool includes a milling head and a mechanism for vertical and horizontal movement of the milling head. The transfer mechanism consists of a skimming3 922

along the timber of the trolley 1, the ball-mounted housing 2 and the hydraulic-arm 3. In the housing 2, an arrow 4 is hinged, on one end of which an electric motor 5 is mounted on the bracket and the milling head 6 on the other.

The milling head b contains conical and cylindrical mills 7 and 8, mounted on the shaft 9, mounted in 10 supports. The shaft 9 rotates in the bearings 10 from the pulley 11. The bearing 10 is installed in the housing 12 and fixed by clamping covers 13 and 14, assembled through the spacer 15 on the plate 16. 15

A copier 17 is hingedly mounted in the support on the housing 12 by means of a bearing 18, fixed by sleeves 19 and clamping covers 20.

Additional pruning residues milling 20 working body as follows.

Timber from the longitudinal conveyor is fed by the ejector to the rotation mechanism. The milling head 6 with 25 using the hydraulic number 3 is in the upper extreme position. Simultaneously with the beginning of the rotation of the timber, the rotation of the electric motor 5 is turned on, which, through pulley 11, transfers the rotation to the mills 7 and 8, and turns off. hydraulic cylinder 3. Under the action of the weight of the boom 4 and its own weight, the milling head 6 is lowered onto the rotating timber, in contact with copying $ ₃ 17. his po18 4

surface and having at the same time the same linear velocity in. ground touch copier with bark. Using the trolley 4, the milling head 6, moving on the copiers 17 along the rotating timber, protects the remnants of the branches and does not damage the surface of the bark.

Installing the copier in the shaft support of the cutter rotation allows reducing the width of the mill head, which reduces the collision frequency of the non-working parts of the mill head with the remains of branches and improves the copy quality.

The use of the milling working body of the proposed design in machine tools for additional cutting of the residues of boughs on timber materials allows processing them in accordance with the requirements of current standards.
