Description

one

The invention relates to equipment for the woodworking industry, in particular, to a rotary debarker core saw.

There are known pickups of rotor type debarking machines, made in the form of a lever with fastening fla.nts; in the upper part and the bent lower part bearing the knife with a sharp cutting edge and a face that is a copier that limits the depth of cut.

A disadvantage of the known spargers is the poor quality of debarking and stripping of the stumps of the branches, especially near the ends of the logs, and also the killing of the cutting edge of the knife into the wood of the end part of the logs.

The purpose of the invention is to increase the quality of debarking and stripping of branching hemp near the ends of logs.

To do this, at the end of the bent lower part of the lever, an emphasis has been made, inclined in the direction of movement of the log toward the cutting edge of the knife, which, together with the knife and the lever arm, forms an L-shape.

FIG. 1 shows a schematic view of the proposed spar, side view; in fig. 2 - the same, view from the exit of the log from the rotor of the machine; in fig. 3 - the same view from the feed side of the log into the rotor.

The pick-up box is made in the form of a lever 1 with a mounting flange 2 in the upper part and a bent lower part 3, onto which a removable knife 5 having a sharp cutting edge 6 and a rear face 7, which is a copier, limiting the depth of cut, is fixed with the help of a secret screw 4. At the end of the bent lower part 3 of the lever 1, there is an emphasis of a descent 8 with a working edge 9

inclined in the direction of movement of the log in the direction of the cutting edge 6 of the knife 5 and forming together-with the resistant lever 1 and the knife 5 L-shaped. Works coring as follows.

When a log is fed into the rotor of the debarking machine, with its end face it acts on the lead edge (not conventionally indicated in the drawings) of the lever 1 and brings the picker onto the work surface. In the process of further movement of the log, the cutting edge 6 of the knife 5 produces debarking and stripping of the branches, and the rear edge 7 limits the depth of cut, ensuring

high-quality processing of the surface of the log. At the moment when the log leaves the rotor of the machine and leaves the surface of the rear section 7, the gathering stop 8 with its working edge 9 is lowered onto the treated surface of the log and prevents the knife 5 from penetrating the wood, ensuring high-quality processing of the logs near their ends.
