The invention relates to the transport engineering and can be used for transportation and sorting of timber (logs, assortments) at the enterprises of the timber and woodworking industry.

The aim of the invention is to increase reliability.

FIG. 1 shows a longitudinal conveyor without a log, general view; in fig. 2 - the same with a log.

The longitudinal conveyor includes guides 1, a traction body 2 connected with cross-bars in the form of bases 3 with saddles formed by swiveling combs 4, which are mounted on hinges 5 attached by pillars 6 to the consoles of bases 3. Rotary combs 4 are connected to bases 3 by elastic elements, for example, springs 7. The teeth 8 of the rotary combs 4 are made with an increase in the size of the teeth (height and width) from the axis of the traction device 2 in the direction of the bases of the bases 3. The traverse bars are mounted on the longitudinal guides 1 by means of cat 9. Longitudinal guides 1 can be positioned horizontally or tilted (for example, when unloading logs from the pool to the shore or to a woodworking machine).

The longitudinal conveyor works as follows.

Timber is fed individually on traverses moving along the longitudinal guides 1 on the rollers 9 by means of a traction body 2. When loaded under the action of gravity of a log, the rotary combs 4 are displaced by hinges 5, overcoming the rigidity of the springs 7, and clamping the teeth 8 with a log (Fig. 2) . When this occurs, the impact of the log along the traverse is mitigated by damping dynamic loads with springs 7. When loading logs with a minimum diameter, the surface of the logs comes into contact with 8 teeth of smaller size located in the middle of the saddles, and when loading logs with a maximum diameter - with teeth of 8 larger diameter . This ensures reliable fastening of logs of different diameters on the crossheads and reduces damage to their surface by the teeth 8. Due to the fact that the rotary combs 4 have an offset from each other, the log, regardless of the presence of surges on its surface, branches, curvature, applies to all

15 traverse under it. This ensures uniform loading of all traverse and eliminates the wear of the rollers 9 due to overload. For dumping logs from the cross-arms, known constructions of dumping 2θ forced-type actuators are used.
