SU50071A1 - Adaptation for multiraft log raft - Google Patents

Description

The author's certificate No. 30618 describes a device for a multi-raft of logs by flooding the bottom tile and gradually pulling the top tile onto it, forming the second row of the raft. According to the author's testimony, a frame is applied reciprocatingly moving towards the upper tile, at the same time flooding the lower tile.

This device has the disadvantage that at the end of the sliding of the upper tile, the entire rafting unit must be stopped for the time required to remove the finished member from the frame.

In order to eliminate the noted deficiency according to the present invention, the reciprocating double frame is composed of two detachably connected parts, one of which, equipped with weights, is intended to flood the bottom tile, and the other is to push the upper row of logs onto this tile. In this case, the automatic separation of the frame parts at the end of the upper row of logs onto the tile is completed, which allows for a continuous rafting process.

In the schematic drawing of FIG. 1 shows the proposed device, a side view; FIG. 2 is the same in terms of; FIG. 3-part of the mechanism separating the frame parts, - side view; FIG. 4 - the same in the plan.

Continuously coming from the rafts of the hall aggregate (not shown in the drawing), the slit of logs 9 is pushed forward by pushers 7 / each swinging around a fixed axis by means of a connecting rod 75 coupled to a J4 screw mounted on the engine shaft (Fig. 1 and 2 ).

To flood the advanced brush, a frame 2 is placed on it, equipped in its front part with heavy weights, for example logs 4, and connected to the pushers by means of cables 5 attached to the crossbar 7

frame.

An impelling part 5, fitted with a transverse bar 7, which, abutting the frame in motion, at the ends of logs 8 brought into the frame, pulls them onto the lower tile to the front end of the flood part of the frame. To keep the latter from the reverse movement, the pawls 72, which rest against the last brevio tiles and are easily deflected by a log, coming from the rafts of the hall aggregate, serve.

The overhanging upper row of logs part 5 of the frame is connected with the flooding

partly by means of coupling hooks 19, which are put on the pin 6 at the end of the flooding part of the frame (FIGS. 3 and 4). Each drawbar is pivotally mounted on a vertical pin 20 and provided with a shank 17, the end of which is connected by a flexible rod 16 to a vertical lever 15 pivotally located at the end of the thrusting frame part.

The pin b is inserted into the plug 18 attached to the front of the thrusting frame, which is engaged with the flooding frame with the hooks 19.

When the upper row of logs is completely slid onto the lower tile, as the frame 15 is further pulled up, the arms 15, which are somewhat submerged in water, are pressed into the nearest log of the lower row and log P, rotated behind them, 16 which in turn will bring the hooks 19 out of engagement with the fingers 6, thus disconnecting the thrusting part of the frame from the flooding.

The two-sided joint thus obtained, together with the advancing frame part, is retracted to the side, and in its place pre-prepared plants are prepared.

the logs of the upper row of the next member, knocked down in its impending frame, meshed with the flooding part.

The subject matter of the invention.

1. The form for making the fixture for the multiraft log raft according to claim 1 of the author's certificate jY 30618, characterized in that the reciprocating moving frame is composed of two separablely connected parts 2 and 5, of which the first one, equipped with weights, is designed to flooding the bottom tile, and the second — extending the top row of logs onto this tile.

2. The form of making the device according to claim 1, characterized in that for the automatic separation of the frame parts after the sliding of the upper row of logs onto the tile is completed, the vertical lever 75 located at the end of the thrusting frame is connected by a flexible link with the rotary coupling shank hook 19, withdrawn from the lock on the flooded part of the frame when the lever is deflected due to the emphasis in the nearest log

i bottom tile. to the dependent aitor certificate of K. E. Maximov L1 “50071
