Description

The invention relates to the forest industry, can be used in the cleaning of branches on roundwood with simultaneous cutting and is an improvement of the known device according to the author. St. No. 1192989.

The aim of the invention is to increase productivity.

FIG. 1 shows a kinematic diagram of a rotary debarking machine; in fig. 2 is a section A-A in FIG. one; in FIG. 3, node I in FIG. 2; FIG. 4 is a view B of FIG. 3

The machine contains the base 1, on which the pinion gear 2 is installed, meshes with the gear-rotor 3, the pinion gear 2 is connected to the engine shaft 4. The movable bodies 5, in which the cutter drive gears 6 and the parasitic gears 7 are mounted, are attached to the crown of the gear-rotor 3. The parasitic gears 7 are in constant engagement with the gear 8, which is rigidly connected to the additional mobile housing 9 mounted with bearings on the base 1 and driven in rotation of the V-belt transmission 10 from the engine He eats 11 fitted with a brake 12. On the shafts of the gears 6 there are mounted bodies 13 of bevel gears, and on the shafts of the driven gears of these gears there are mounted mills 14 with copiers 15. The locking mechanisms 16 are fixed on the shafts of the driven members 17 of the V-belt drives installed in additional frames 18. Each frame 18 is mounted with bearings on the shaft of gear 6 of the cutter drive 14, on which the driving element 19 of the belt transmission is rigidly mounted. Each frame 18 is provided with a fixed-edge bar 20 and spring-loaded sliders 21 and 22, one of which 21 has an abutment 23 and the other 22 has a wedge projection 24. Each copier 15 is equipped with a pressure bar 25 for interacting with the sliders 21. The bar 25 has an end portion 26 in the form of a threaded pin, a nut 17 and a spring 28 for adjusting the clamping force of the debarking mechanism 16 to the log 29. The base 1 is provided with radially mounted elements 30 and 31 for interacting

VIA with sliders 21 and 22 respectively. On bevel gear housings, counterweights 32 are attached to clamp the cutters 14 to the log due to centrifugal forces. To return the cutters 14 to the initial position, the bodies 13 are provided with springs (conventionally not shown).

Rotary debarking machine works as follows.

Engine 4 is turned on at a reduced speed, with gear 2 and gear-rotor 3 being driven in rotation. Together with the gear-rotor 3, the movable bodies 5 rotate, in which, by obeying the crown of the gear 8, the parasitic gears 7 rotate. They receive the rotation of the gear 6 of the cutter drive 14, Through the gear shafts

20 6, the driving elements 19 of the V-belt drives and the bevel gear gears located in the housing 13 are rotated. At this point, the cutters and debarking mechanisms due to the action of springs and centrifugal forces which increase the centrifugal forces to the counterweights 32, are wrung out of the log and mc in the extreme position fixed by the limiters (conditionally

30 not shown). The feeding device logs 29 into the machine in the direction of the arrow B. The operator assigns the processing mode (with or without a debarking bar), and if a debarking is needed, then at the moment of the end of the log in the plane of rotation of the debarking mechanisms 16, the movable element 30 acting on the slider 21 advances When the beveled end of the slide 21 comes into contact with the element 30, the slide 21 moves in the guides 33, while the stop 23 lifts the fixing bar 20, turning it on the axis 34 and compressing the spring 35.

45 20 by the stop 23 of the slider 21 is fixed as shown in FIG. 3. At this point, the engine 4 is switched to the increased speed and the engine 11 is switched on. Herewith the gear wheel 8 is connected by means of an additional movable body 9 and the V-belt drive 10 with the motor 11, rotates in the direction opposite to the rotation of the gear-rotor 3, increasing the speed of rotation of the cutters and debarking mechanisms around their axes. At the same time, the centrifugal forces acting on the counterweights exceed the forces that act

Heads for cutters and debarking mechanisms and spring resistance. Copier cutters are pressed against the surface of the drum. At the same time, the pressing plan ka 25, resting against the end part 26 in the slider 21, presses against the log and the frame 18 with the debarking Mechanism 16.

With further advancement of the log, its debarking with the stripping of the remains of the branches occurs.

After processing the entire log, the motor 4 is switched to a reduced speed, and the motor 11 is turned off and its shaft is braked by the brake 12. The cutters and debarking mechanisms rotate to their original position.

If OKOpK i of the subsequent log is not necessary, then at reduced engine speed 4 the operator advances element 31 acting on the slider 22. With further rotation

the rotor, the ends of the sliders 22 alternately slide onto the element 31, move in the guides 33 and lift up their wedge lugs 24 of the locking mechanism 20, while the released sliders 21 return to their original position and then clamp the debarking mechanisms to the surface.

10 of the log does not occur, since the end part 26 of the push bar 25 does not come into contact with the slider 21. As the log advances, only the stripping of the branches occurs.

15 The use of a remote controlled clamping of the ocular organs allows, depending on the purpose of the timber, to treat it with debarking or only with stripping.
