Description

(5) DEVICE FOR SORTING TREES

t

The invention relates to log sorting devices and can be used in the forestry and woodworking industry.

A device for sorting logs p is known, containing a trestle on which a longitudinal conveyor is located, and drives made with guides are installed at the base of the trestle.

However, the device is unreliable in operation, does not prevent the running of the butt against the top during the fall of the logs, which does not allow to form a stack of logs in the drive with relatively aligned ends.

The aim of the invention is to improve the quality of stacking logs in drives.

This goal is achieved by the fact that the known device, comprising a trestle on which the longitudinal conveyor is located, and log drives, located at the base

The overpass has a shaft with asterisks and free-running chains thrown over the accumulators along the overpass, at least two starlets are mounted above each drive, the chains are installed with the possibility of height adjustment by means of a shaft drive has a notched comb fixed to it.

FIG. 1 shows a kinematic schematic diagram of the device; Fig 2 is the same, top view; in fig. 3 designs of one chain link.

The log sorting device comprises a longitudinal conveyor 1 mounted on a ramp, at the base of which drives 2 are located. Above drives 2 a shaft 3 is mounted, on which two asterisks k are placed above each drive. Through the asterisks, two E9 round link chains 5 are thrown over the chain 5. A chain comb 6 is welded through one link, which increases the holding force of the log and prevents the butt run against the top. The chains 5 can be adjusted in height as the logs accumulate in the pockets of the accumulators 2. To lift and lower the chains 5 there is an electric motor with a reducer 7 connected to the shaft 3. The overpass also has an inclined plane 8 to roll the logs into the hopper 2. The device works as follows in a way. When the log moves along the transport unit 1, it automatically stops with in front of the corresponding accumulator 2, it is reset and, on an inclined plane, the log rolls into the accumulator. Chain 5 with its mass extinguishes the kinetic energy acquired when the log is rolling along an inclined plane. The pad into drive 2, the log falls between chains 5 and the inner wall of the drive. Since the deviation from the vertical of heavy chains 5 requires certain efforts that are still increasing due to the toothed combs welded to the chain links, the fall of the log slows down, and most importantly, the race between the butt of the log and its top is level and the logs are laid into the hopper smoothly.

Claims (1)

 1/4 I 1 As the accumulator 2 is filled with the drive of the shaft 3, the free-hanging branches of the chains 5 are shortened. After the accumulator 2 is released, the circuit 5 is again lowered to the predetermined depth, and the cycle is repeated. This design of the device allows a significant reduction in the rate of falling of the log, prevents the running of the koml against the top of the log, and thus allows forming a package of logs in accumulators with relatively aligned ends. Claims A log sorting device comprising a trestle on which the longitudinal conveyor is located and log drives placed at the bottom of the trestle, characterized in that, asterisks and free-running chains thrown over them, with at least two asterisks mounted above each drive, the chains are mounted for height adjustment by means of a drive shaft And in every second chain link has mounted thereon a toothed comb.
