Description

one

The invention can be used at logging enterprises for the priest: river cutting of wood.

Splitting installations are known, including a feeding and receiving device, a fixed housing, inside of which a gear wheel with guide rails for reciprocating movement of the cutting member and driving the cutting member is installed.

The purpose of the invention is to simplify the design, to ensure a reliable return of the cutting body to its original position after the working cycle.

For this purpose, the drive of the cutting organ is made in the form of rollers mounted on the latter, moved along guides mounted in the non-movable housing, displaced relative to the feed center.

On f | ig. 1 shows the proposed installation, side view; in fig. 2 - the same, front view.

Splitting installation contains feed 1 and receiving 2 devices, stationary body 3, gear wheel 4 with guides 5 and drive 6, cutting member 7 and drive of the cutting member made in the form of guide rollers 8 "interacting with them" 3 9, mounted on the cutting body 7, the guides 8 are made around a circle offset from the center of the log feed. To ensure the cutting body returns to its original position after the working cycle, it is spring-loaded relative to

gear 4 with, for example, 10. For cleaning the guides 8 from dirt and debris, the cutting body is provided with a cleaning device made, for example, in the form of brushes 11. A whip is fixed in

the desired position of the clamping device 12.

Before starting work, turn on the drive motor 6. With the help of the feeder 1, the whip is fed to the cutting unit.

to the position fixed by the device for measuring the lengths of the assortments and fix it in this position by means of the clamping device 12. The drive 6 is turned on, and the cutting element 7 together with the guides 5 starts

rotate around the whip, and the rollers 9 of the cutting body 7, moving along the guides 8 of the stationary body, push it onto the whip. TaiKHM method for one revolution of the cutting body from the halgs cut a block of a given length.

As a result of this kinematic cutting, the cutting force decreases and the productivity of the installation increases. The return of the cutting body to its original position after

The cutting is done with the help of the springs 10.

Cut log with the help of the receiving device 2 enters the sorting conveyor. Then the remaining part of the whip is fed under the cutting and the cycle is repeated. The cleaning of the guides 8 of the stationary body 3 is carried out by the brushes 11, sliding along the guides 8 during the cutting unit in the direction of the log.

The operation of this installation can be controlled by the operator from the control panel.

Subject invention
