(54) DEVICE FOR INSTALLING A TREE IN A TRANSVERSAL BRUSH

The invention relates to a water granaport of a forest and is intended for placing logs in a transverse chain on rafting and sorting rafting.

It is known a device for placing a shave in a transverse grain before feeding them into the sorting corridor, which includes a floating base in the form of pontoons connected by transverse bridges, on which there are supports with drums for heating the logs moving between pontoons.

A disadvantage of the known device is the IB that the logging corridor arrives in an inclined position. Therefore, they restrain the movement of the aunts of the logs there, violate the position of this nest and exclude the possibility of affective use of accelerators of movement (this section of the copTHpoBOHFioro corridor.

The purpose of the invention is nOBbiiJj; .niie device reliability in operation and reduction of eio dimensions.

This goal is achieved by the fact that on one of the transverse bridges there is a mechanism for turning the logs, made in the form of a cross and provided with a drive with a double-acting hydraulic cylinder that interacts with the cross by means of a cable block system, with restrictive shits attached to the ends of the cross and on the supports additional drums for cutting logs.

FIG. 1 shows the proposed device in plan, a general view; in fig. 2 scheme of work flooding and log trimmer.

On the transverse bridge .1, mounted on two pontoons 2, the log turning mechanism, made in the form of a crosspiece 3, is hinged together. It is designed as a crosspiece 3. To eliminate the load on the bridge J from the weight of the crosspiece, the buoyancy reserve is provided.

Limit shields 4 with stops 5 are hingedly attached to the ends of the cross-piece.

Logs are fed into the device with the help of typical drum boosters 6

And on the transverse bridge 7 mounted on joeyx common; supports 8 flooding gel 9 logs of the drum type and a longitudinal brush cutter made from two drums 10 and 11. Onors 8 are connected to hydraulic cylinders 12 located on bridge 7 (in Fig. 2, the second support and the bridge are not shown). The mechanism for moving the brush of the logs is attached to bridges 1 and 13, and in the full beam in the form of two guides 14

and 15, in which the carriages 16 move with the posts freely bending in the direction of flow. And to the bridges 7 and 1, and from above to the guides 14 and 15, a guide path 17 is connected for a displaceable carriage 18 with a folding stand. To prevent wear of the cable 19, supporting carriages 2O are attached thereto.

The drive of the carriages 16 and 18 is made from a common hydraulic cylinder of double-sided action 21, by means of drums 22 and 23i and a cable block system. There is a hydraulic cylinder 24 on bridge 1 for stopping the spider.

Above bridge 7, on one of the pontoons, a crane with a jaw grip of 1 lightweight carrying capacity (near YuOOk, known in wood-floating enterprises as a mechanism for the development of emergency logging) is installed. Its purpose in this device is to harvest lengthy logs from the corridor to a special courtyard.

The device works as follows

The initial position of the cross 3, while in FIG. one.

The stand of the carriage 18 is engaged with the stop 5 of the shield 4, and the carriage 16 is located at the bridge 13,

At the start of operation, the flooder with the cut-off valve is set to the position (Fig. 2). Drum boosters 6 are turned on, and the logs are fed to the spider. When the individual logs begin to end up facing, the floater and the cutter switch to the b position and the ends located upstream of the logs are submerged.

When ukkrestoviny pick up the brush

the logs, the deluge and the slam-shut are moved to the position. The logs located below in the flow, under the action of their weight, roll up Tsots on drum 11 to the cross, and logs located downstream, on drum 10 into the supply corridor. At the same time, individual logs are held by accelerators 6 in an inclined position, not interfering with the work.

At the moment when all the logs below the floodwater are in the water, the hydraulic cylinder 24 is turned on and then the hydraulic cylinder 21.

The stand of the carriage 18 through the stops 5 of the shield 4 by means of the drum 23 and the cable-block system connected to the hydraulic cylinder 21, causes the spider to rotate. At this time, the carriages 16 move from bridge 13 to bridge 1.

By the time the rack of the carriage 18 approaches the guide 15, and the carriage 16 approaches the bridge 1, the hydraulic cylinder 21 stops c. The cross is further driven by inertia. In this case, the shield 4 comes out of the engagement with the stand of the carriage 18 and, under the action of the flow, turns around along the stream, freeing the log gap. At this point, the hydraulic cylinder 24 is again turned on, the spider reaches it and stops.

Further, the hydraulic cylinder 21 is turned on in the opposite direction, as a result of which the carriage 18 is simultaneously returned to its original position, and the carriage of the carriages 16 is pulled out of the device. After the new lash of the logs is picked up at the cross, the reversal process is repeated.
