SU41673A1 - A device for cleaning bark and dirt and washing on water of logs intended for cutting - Google Patents

Description

It is already known to use log washing in sawmills, which, when fed to frames, a log passes through a pipe, inside which it is surrounded by circumferential streams of water, and the very moment of contact of the water jet with the surface of the log is so short that the log is poorly washed. When sawing, the sand remaining in the logs, IL.1 etc., saw the teeth of the saws dull. Shutting down the sawing mill plant is mainly the result of poor rinsing; it is even harder to wash the summer roll-out logs in winter, when the logs are covered with sand penetrating into the pores of the bark; in addition, the frozen log is generally poorly washed in winter.

In order to achieve a better washing of the logs, it is proposed to wash the logs before lifting and raise them into the stacks already washed, due to which washing out of them during sawing is eliminated.

According to the invention, on two parallel rafts connected to each other, incisal rollers are placed, positioned axially to the horizon and intended, in addition to crushing the bark, also to rotate

and axial movement of the logs between the rafts. During the passage, the logs are washed {in the path of water supplied through the turbopump tube.

In FIG. 1 is a side view of the device; FIG. 2 - its top view; FIG. 3 is a front view along arrow a in FIG. 2

On two parallel rafts interconnected, an electric motor 1 is installed (FIGS. 1 and 2), which informs the rotation of the turbopump 2 and the two connected chain transmission 4 to the shafts 5 with Hooke's hinges, transmitting the movement to the cutter rollers-8 buks located on each the raft. One of the shafts 5 is connected with the carriage 6, which carries one of the incisal rollers-b bay 8 and moves under the action of a load in order to accommodate a device for treating logs of various thickness by continuously and forcibly pressing them onto the roller 8.

Roller 9 serves to center the log; the turbopump tube 3 is connected to the last rubber hose 10 to level its position. To guide the movement of the carriage 6, the rails 11 are used for its rollers (Fig. A).

Shrek {the arch 7 of one raft with his roller resting on the other raft serves to evenly support the movable roller-r of the bukh 8.

When the device is in operation, an electric motor reports rotation to the rollers-r to the bukham 8, which slightly compress the log. The cutting teeth of the rollers-b Bukh 8 are located in relation to the log so that the log simultaneously receives rotational and translational motion, with the bark on the log being cut. With a strong rotation of the log, dirt and bark are removed from its surface and at the same time turbopump 2 washes the logs from pipe 3 with water under pressure.

The subject matter of the invention.

Claims (3)

1. A device for cleaning bark and dirt and washing on water logs intended for cutting, characterized in that on the other side, two parallel rafts are installed in supports, driven cutter-rollers of the bukh 8, which are axially inclined to the horizon and intended, in addition to crushing the bark, also for rotation and axial movement between the rafts of logs washed on the way with water supplied through pipe 3 turbo pump. 2. The form of the device according to claim 1, characterized in that the transfer from the motor axis of the incisal rollers-b 8, mounted on both of the rafts, includes shafts 5 g of Hooke hinges and an endless chain 4 and one of the axes, associated with the carriage 6, receives a lateral displacement under the action of the load in order to adapt the device to the processing of logs of various thicknesses. 3. In the device according to claim 1, the support roller 9 is used for adjusting the position of the log relative to the constant incisor roll-bua 8. srig-f cjjur.Z CFJUF-S
