Abstract

The invention relates to the forest industry and can be used in rotary debarking machines. The goal is quality improvement. On the rotor 1 of the machine, the holder 2 is mounted with a clamp 3, a cutting knife 4 and 5, one end of which is fixed to the rotor by the hinge 6 and the other end to the knife 4 mounted with the ability to move the clamp 3 into the groove. D ₁ to D _{2 The} holder 2 of the pick-up magnet rotates through an angle α, and the ton ha 5 turns through an angle β. At the same time, the knife 4 is moved, which, depending on the change in the angle α, automatically adjusts the depth of cut. 2 Il.

FIG.

The invention relates to equipment for the woodworking industry and can be used in rotary debarking machines.

The purpose of the invention is to improve the quality of debarking timber.

FIG. I depicts a scheme of the herbs of the mat; in fig. 2 - location of the barrel at different log diameters.

The pick-up box contains a holder 2 with a lock 3, a cutting knife 4 and a thread 5 mounted pivotally on the rotor 1 of the machine, one end of which is fixed by a hinge 6 on the rotor offset relative to the axis of the holder 2. The lock 3 has a guide groove 7, the other end The gi are hingedly attached to the knife 4 mounted with the possibility of movement in the guide groove 7. The feed bushing is spring-loaded with an elastic element 8

The collector works as follows.

When feeding the timber into the working area of the rotor I, the Carbide Chopper, through a run-in device, brings a knife 4 to the surface being processed, which begins to cut the bark. A change in the diameter from tJ to il (Fig. 2) leads to the rotation of the mold, pressed to the surface to be machined elastic by the element 8, by an angle a. and ti 4 on the angle p. At the same time

baking the movement of the knife 4, which is pivotally connected with the second end of the rod, in the groove 7. Since the rod 5 is installed in the rotor with an offset from the axis of the borer in the direction of rotation of the rotor, the angle a increases. causes an increase in the depth of cut by the value of Le. With a decrease in the diameter of the log, and hence the thickness of the bark, tons ha 5, making a reverse movement together with the borer, moves the knife 4 in the guides, reducing the depth of cut. Thus, the proposed picker allows you to adjust the output of the knife to cut the entire layer of bark, and thus improves the quality of the debarking when the diameter of the treated log is changed.
