Description

The machine is intended to produce a raft of logs in bunches of different cubic capacity with different draft and with different distances between the axes.

A distinctive feature of the machine is the use of viscous and pushing out log beams of an underwater horizontal conveyor, strutting, strut, they are cradles. Due to this transporter, the rafting of logs into bundles occurs without stopping the working parts of the machine for the duration of the beam unloading. In this case, the manual operations for linking the beams are minimized and consist only in connecting the ends of the tie. Wire or chain kits can be used to tie beams.

In FIG. 1 is a top view of FIGS. FIG. 2 is a section through AB of FIG. one.

A machine; It has a floating base in the form of two pontoons 1, which are interconnected in the bow and stern with two bridges 2 and two trusses 3 - in the middle part. On the farms 3 there are two branches of the elevator lift 4 for lifting logs from the water, and the receiving part of the elevator is strongly curved and forms a small angle with the water horizon. In addition, the lifting elevator 4 has a drainage part 5, which can be adjusted depending on the height of the produced beams.

In the middle part of the machine, a horizontal underwater conveyor b is installed, which has on its chains special elongated posts 7, which form cradles for receiving logs, to be bundled.

The horizontal conveyor 6 is lifted out of the water with the aid of a system of blocks on the ropes through a drum, driven by a manual winch 9. The lifting mechanism can be constructively made of another kind, for example, with vertical gear screws: gearboxes. The drive of the elevator 4 dried, is driven by an electric motor 10 part of the gearbox I.

The drive of the horizontal conveyor 6 is carried out with the aid of, and

vertical shaft 12 with bevel gears and gear 13 from the motor 14.

Above the horizontal conveyor 6, two ladders 15 are installed for workers who make bundles of ties.

To eliminate the possibility of the logs rolling under the elevator, racks 19 are installed, and a beam with guards against the 5 logs falling from the outlet elevator is installed in front of the ladders 15 for safe operation during bundling.

The wrapping in the form of wire or chain sets is fed through guide rollers from the coils 17 mounted on one of the pontoons and further strengthened to the uprights of the 7 horizontal elevator 6. In this way, the logs falling from the elevator 5 fall directly into the ground.

The binding posts 7 are interconnected at the ends and have clamps to secure the binding.

When transporting the machine from one job to another, the elevator 4 is lifted out of the water by hand winches installed on both pontoons. Also, a horizontal conveyor 6 is lifted out of the water by means of a winch 9. The working bodies of the machine lifted out of the water are fixed and the machine is ready for towing.

The operation of the machine is as follows.

The machine is installed under one of the sleeves of the raid screen. Sorted wood is fed with a continuous brush to the receiving part of elevator 4 and directed to two hooks on the hook of the elevator.

Logs, going to the elevator, go into the cradle horizontal

conveyor 6, which all the time moves at a slower speed against the speed of the elevator. To protect the horizontal

The conveyor from the blows of falling logs at the work site are placed two bombs on either side of the horizontal conveyor (the booms are not indicated in the drawing).

The booms are made from dry bars and are at the same time buoyant bases for the beam, which, due to a certain buoyancy of the booms, is raised from the bottom to the required height needed to get the correct shape.

The length of the beam depends on the width of the beam and is determined at the work site.

After filling the cradle with logs, the workers descend onto the beam and tie it up with pre-fixed sets of ties or wires. In the course of the linking time, the next beam is made, and the workers are transferred to it to link it, and the finished beam leaves the machine as the horizontal conveyor moves further.

When switching from one type of product to another (changing the size of the beams), the horizontal conveyor of cradles rises from the water, the conveyor chains are disassembled and the posts 7 are rearranged to the desired size of the products.

The subject matter of the invention.

Tight beams are a continuous filling machine, characterized in that a drive, horizontal, underwater conveyor, equipped with racks 7, forming cradles, is used for binding and pushing out beams of logs.
