SU78293A1 - Continuous rafting machine for beam raft logs - Google Patents

Description

The invention relates to a rafting machine, for beam rafting of logs that are extracted from the water of an elevator and transported by them into a packaging device for subsequent rafting.

In the proposed continuous raft tire, the elevator receives a continuous stream of logs, delivered, and transfers them to a baler, which is made in the form of two endless chains, suspended from the beams, moving along the inclined rails. The formation of both small and painful beams is carried out in these chains over the canopy with automatic transfer of the strapping material to wrap the beams along the metal grooves.

The drawing shows a longitudinal vertical section of the proposed machine.

The machine consists of two pontoons / connected to each other by a front axle 2, to which a rack 3 is attached to stop the freight bars. The cargo beams 4 are moved along inclined rail 5 and interconnected by an endless calibrated chain 6,

envelope Tj, ep 7, driven by a winch 8.

The chains hanging from the towers form a bundle of lyulki 9, into which logs freely fall from the brackets 10, are fed to the brackets by an elevator P. For greater strength, the pontoons of the machine are connected by a second bridge 12 and an underwater suspension 13 is used for cargo beams, and a farm 14 for supporting the elevator.

At the initial rafting moment, logs in the form of a brush are deposited by surfacing to an elevator and then sent by workers to an elevator hook. Captured a continuous stream of logs from the e, the levator enters the brackets, and then on the circuit of the packet-fed device. In the first stage of the formation of the beam, the chains of the cradles of the canopy are folded; As the logs accumulate in the cradle, the towers are turned off and the further lowering of the beam is controlled by the brake until the cradle is filled to the specified beam volume. Then the elevator is stopped and the bundle is tied with a braid material (wire, cable, etc.)

from the pontoon along the metal troughs 15. A similar operation is repeated 3-4 times, until the entire length of the loading rails is filled,

When the entire length of the rail is filled with bundles, the stop stands are opened and yet another, the cargo beam that rests against the stands freely falls into the water, freeing the bundle. The stands of the stop are immediately closed, and the cargo beams roll down the inclined rails, carrying along the formed beams. In this connection, under the brackets, there is a place to be, another cargo beam fits, and the beam forming process continues uninterruptedly.

Subject invention

A continuous compacting machine for the beam foundation of a breben, extracted from the water by an elevator mounted on a pontoon, is characterized in that the elevator receives a continuous continuous stream of logs and transfers them to a packaging device, which is made in the form of two endless chains suspended from beams moving These are inclined rails, with the formation of both small and large beams produced in these avesa chains with automatic feeding of a binding material for wrapping the beams along metal troughs.
