Description

The invention relates to the forest industry and can be used in the hydraulic debarking of wood.

The purpose of the invention is to increase efficiency.

Figure 1 shows a roller table, top view; figure 2 is a view of And figure 1; Fig. 3 shows the hydraulic scheme of the machine.

The machine contains a frame 1, a wood feed mechanism 2, a centering mechanism 3, a rotation mechanism 4, a roller table 5, a hydraulic pulser 6, a distributor 7. The centering mechanisms 3 and 4 rotations are mounted on the links of the pantograph 8. The rotation mechanism 4 is located on its side links 9 and is made in the form of rollers connected to the drive shaft 10. The central link of the pantograph is equipped with an anti-roll roller 11.

The roller table is made in the form of blocks, each of which combines a hydro-impulse unit 6 with an articulated-lever device 12, which, by mechanical action, has the ability to deviate from the machine axis in a plane perpendicular to it, and to return to its original position 13.

The hydraulic impulse units are connected in parallel to the switchgear 7. The machine also contains pipelines 14 for supplying water and air, a receiving conveyor 15, a tray 16 for discharging waste water, a mesh conveyor 17 for separating the bark, a harvesting conveyor 18.

The device works as follows.

Timber 19 is fed to the roller table 5, the mechanisms 3 and 4 are rotated and pressed against the table, while the suspension of the pantograph 8 allows you to track the curvature and defects of the shape of the processed log. The log makes a rotational motion, while the roller table units, combined with the hydraulic pulse units 6 and the hinged-lever device 12, move the hydraulic pulsator in a plane perpendicular to the machine, following the change in the shape of the log, tracking the formed jets for optimal processing parameters. The distribution device 7 is supplied with a fluid successively to the hydraulic impulse devices (the working jets move along the axis of the log). The processing time of a single log is increased by the time of immediate processing, the time of supply and dumping of the log remains similar to the machine with a cross feed, therefore, when the installed capacity decreases with small processing volumes, the energy consumption and water consumption per unit of raw material is reduced.
