Description

one

The invention relates to logging equipment.

Devices for cutting branches from felled trees are known, which contain a frame, swivel pinch levers, curvilinear but power cut ki, feed conveyor, with rolls and hydraulic drive.

 The clamping and delimbing organs in these devices are performed each with their own hydraulic actuator, which makes the deliming devices much more difficult and difficult to control the latter.

The purpose of the invention is to predict the design and increase the efficiency of work.

The goal is achieved by the fact that the cauterized bolt and the valod and the knives of the power unit were installed pop-but on the different shoulders of the U-shaped strings attached to the swiveling levers. Moreover, the power cutting knives are made with double-sided cutting bars and mounted on bridges using quick-release couplings.

FIG. shows the proposed device, front view; figure 2 is the same, top view.

On the base section of the I welded structure of the device is mounted feed

conveyor 2 with hydraulic motor 3. The press rollers 4 and the side curvilinear knives of power cutting 5, having an arcuate furm, are installed in pairs on different U-shaped shoulders 6, hinged 1. by means of axis 7 on turning 1shkh levers 8.

 At the level of the feed conveyor 2, a fixed arcuate knife of the slit cutter 9 is installed. Pryushy levers 8 Open the drive from the hydraulic cylinders 1 Power cutting knives 5 are made with double-sided cutting and mounted on the yokes 6 by means of quick-disconnecting, in the form of a groove and XCocTecTb. shaped section, which allows for fast relocation of the knives for alternately putting their cutting edges into operation.

The device works as follows.

The tree is attached to the device by the upper part of the device and it is attached to the feed conveyor 2 and the fixed knife of the Power Cut 9, pressed by the rollers 4 and the side edge of the power cut 5. Since the shoulders of the rocker arms with the knives 5 are much larger than the shoulders from the back of the rollers 4, the force of the shoulders | Ma knives 5 less effort clamping roller ca 4. Therefore, power cutting knives 5

with a tree trunk. After pruning

U-shaped rocker arms 6, and attached rolls: rings 4 and knives 5 are returned to the original

position, B further technological. the operation is repeated,

 1, Device for cutting knots from fallen trees, curving frame,; swivel hold-down levers, curvature; power cutting neural knives, iTpaHcnopTep pushes, print.1 rollers and a hydraulic drive, differing from the fact that, in order to simplify the design and increase work efficiency, the pressure rollers and power cutting knives of the device are installed in pairs on different shoulder u-shaped rocker arms, hinged on the swivel pressure levers.

2. The device according to Claim 1, characterized by the tempered knives of power resistors, is made with double-sided cutting blocks and is mounted on the cores with the help of quick-connectors, for example, in the form of a groove and a T-shaped shank, ensuring the skin is rearranged with alternating insertion of cutters in the work edges.
