The milling of the milling cutters 2 to the treated timber 14 is carried out by means of a solenoid 6, inside of which a shaft 3 is placed. carried out with the help of the stator electromagnetic winding 9. When the rotor 1 rotates from the engine 12 and the winding 9 is turned on

the gears 7 begin to roll around the rim 10 and the milling cutter 2 obtains rotation, at which point either debarking or pruning of the branches begins. The speed of rotation of the mills is controlled by changing the speed of rotation of the ring 10 by changing the strength and frequency of the winding 9. When current is applied to the windings of the solenoids 6, the shaft 3 moves towards the timber or vice versa. The clamping force is controlled by the current value of the solenoids. 1 hp f-ly, 2 ill.

The invention relates to the timber and woodworking industry and can be used for debarking and pruning boughs from tree trunks.

The purpose of the invention is to increase efficiencies by increasing productivity, reliability and quality.

FIG. 1 shows a stemming ™ rotary rotary machine, longitudinal section; in fig. 2 - section AA on

FIG. i.

The machine contains a drive rotor I

with end faces mounted on it: cutters 2 mounted on shafts i 3, cutter clamping devices and a feeding device 4. Cutters 2 have drop edges 5.

Each clamping device of the milling cutter is made in the form of solenoid 6, which engages it in the shaft 3, and the shaft 3 has a gear wheel 7 with which it contacts by means of a spline connection 8.

The rotational drive of the cutters is implemented in the form of a stator electromagnetic winding 9 having a coaxial gear ring 10 connected to the gear wheels 7 of the shafts of the 3 cutters 2. The direction of elevation of the lead edges 5 of the cutters coincides with the direction of their rotation. The rotor 1 rotates in the stator 11 from the engine 12 through a belt transmission 13

Stem processing machine works as follows.

The rotor 1 together with the cutters 2 and the clamping devices is driven

rotation about an axis 0-0 by an electric motor 12. A coaxial gear ring 10 under the influence of the torque of the electromagnetic field,

5 arising under the action of an electric current flowing in the stator winding 9 is either n-movable or rotates in the direction of rotation of the field of the winding 9 with a speed depending on

About the frequency and power of the flowing current. Due to the fact that the gears 7 rotate coBJjecTHo with the rotor i, they roll over the gear ring 0 and cause the rotation shaft 5 3s with the cutters 2. The speed of rotation of the cutters is adjusted by changing the speed of rotation of the gear ring by changing the strength and frequency

stator winding 9. 0

When logging 14 enters, electric current is applied to the winding of the solenoids 6 of the pressing mechanism. Electromagnetic floor

5 in the corresponding direction, the shaft 3 extends along the halitsy joints 8 in the direction of the rotor axis. The end face of the timber 14 interacts with lead edges 5 cutters 2, which

0 due to the rotation and the lifting lines of the edges 5, which coincide in direction with the direction of rotation, go out onto the forming timber, overcoming the resistance of the electromagnetic field,

5 and debarking with pruning. The clamping force of the cutters is regulated by the amount of current flowing in the solenoid windings.

The forward movement of the timber 4 is provided by the feeding device 4.

The proposed technical solution ensures the operability of the machine in the case of a mismatch between the longitudinal axes of the machine and timber.
