Description

The invention relates to the forest industry and can be used to cut low-quality wood and waste into short grades, for example, chocks 15-20 cm long for wood chemical production or chocks 0.5 m long for wood splitter machines.

The purpose of the invention is to simplify the design.

The system for group transverse sawing of timber into logs contains enclosing shields 1 with a bottom 2, a crossbeam 3, inclined shields 4 and 5, fork teeth b, a transverse conveyor 7, a mechanism for mixing sawn and removal of assortments. The enclosing panels are made along the entire length of the device, the bottom 2 is made at an angle to the fork teeth. The latter perform the function of guides when the device moves and are therefore located below the bottom of the device.

The biasing mechanism is made in the form of leaf springs 8 having G-section, and the inclined shelves are

ig are located at the top. The springs are attached to one of the enclosing panels 1 from the inside using a common mount.

The sawing mechanism comprises a crankshaft 10, a rocker shaft 11 (can be replaced by a crankshaft 10) with wings 12. A plate 14 is suspended on the crankshaft 13 of the crankshaft and the wings, to which the assortment removal mechanism is attached in the form of a gear surface 15, the location of the plates 14 may be different.

The front end of the plates 14 is made in the form of a proppant knife 16, at the end of the 17 gear surface to the support 18 are tensioned using bolts 19 and stitches 20 of the band saw 21 with riveted cross-pieces 22 at the ends,

The crankshaft 10 is connected to the actuators 23, for example a hydraulic motor.

Cuttable longitude is in stack 24, laid on gaskets 25.

Installation works as follows.

There is, for example, a stack of 24 firewood with a length of 2 m, laid on gaskets 25. Installation with fork teeth 6 is placed between the gaskets 25 and, when moving forward, the stack starts to fall apart with the front part. Logs 2 m long fall to the bottom and with the further movement of the installation forward (arrow in Fig. 1) falls on the plate springs 8. They move the logs along so that the ends rest on the inner surface of the second enclosing shield 1. So, gradually to the cross member 3 logs fill the front of the device.

With the further movement of the installation forward, the hydraulic motor 23 is turned on and rotation is transmitted to the crankshaft 10, which rotates the crank 13. The plates 14 begin to make ellipsoidal movements relative to the wings 12, and the tooth of the saw 21 makes a cutting movement from top to bottom.

From the pressure of the stack 24, the logs fall into the hole of the cross member 3 and meet with the saws 21, while these logs cannot be displaced due to pressing by the rest of the logs and pressing from the ends by the springs 8. The saws are made in the form of strip mills, i.e. their thickness is sufficient to form technological chips during transverse sawing.

As the machine continues to move forward, the saws21 saw the log into pieces, for example, pieces of length 0.5 m. The sawn pieces fall on two gear surfaces 15 of the adjacent plates 14. Due to the asynchronous rotation of the cranks 13, the keys 15 start three pieces so that they begin to walk along the serrated surfaces m

The pieces reach the end and dump onto the cross conveyor 7, which feeds them to the stack or to the vehicle. In the first case, the installation remains behind

a long pile of wood churaks suitable for splitting with an ax or other means.

Similarly, the installation works when cutting the balance length (for example, 2 or 4 m long) into meter pieces, sleeper 5.5 m into two parts, and in other cases. To do this, the distances between the support shields 1 and the plates 14 are changed.

The installation is easy to manufacture, eliminates unnecessary transport movements of forest materials, allows the introduction of low-operational technology and has high performance.
