Description

one

Beatifing refers to the forestry industry, in particular to the stripping J machines of the rotary type.

Known debarking rotary machine, equipped with four end mills fl.

When debarking the trunks, this machine cleans out minor remnants of boughs, but cleansing all remnants of boughs, the otlichaku- Yu shshss large diameter range and BbrcoTi machine does not produce because of the design features face mills. In addition, the trimming of the branches without debarking the trunk with this machine is unblemished, and for some conditions, for example, when exporting, the wood must be unrooted.

A rotary branch trimmer is also known, comprising a base 20 connected by means of a gear to a movable body, which is also connected by means of a gear to the cutting bodies 2.

The disadvantage of this machine is the low quality of the pruning of the branches, since the presence of a cutting organ in the form of a pinch mask makes it possible to cut the knot only along a plane.

In addition, to return the cutting bodies to their original position after machining the barrel and feeding the next drive mechanism 1a, it is necessary to pull out, which reduces productivity.

The purpose of the invention is to improve the quality and performance.

This goal is achieved by the fact that the rotary branch stripper is equipped with an additional movable casing with a gear wheel, which is associated with the brush gear of the cutting bodies, the latter being in the form of cutters, and the additional movable casing has an individual reversing drive.

FIG. 1 schematically depicts a rotor rotary machine for branching; in fig. 2 is a view along arrow A in FIG. 1. 39S4 The machine contains a scenario 1, in which the drive gear 2 is installed, the drive drives the gear-rotor 3. The driving gear 2 drives the motor 4. The movable housing 5, in which the gear drive 6 is installed, is attached to the gear crown - rotor 3. Gear 6 of the cutting body drive is in constant engagement with gear and 7, which is rigidly connected with an additional movable body 8, installed with the help of bearings in a stationary body 1 and driven by a wedge belt A 9 from an electric motor 10. Equipped with an electromagnetic brake 11. A bevel gear pinion 12 is mounted on the same shaft with gear 6, and a milling cutter 14 with a cam 15 is mounted on the driven bevel pinion shaft 13. The gears 12 and 13 are located in the gearbox housing 16. The return of the milling cutter 14 to the initial position on the shaft of the gear 6 is mounted on a spring 17, working for twisting, with one end of the spring fixed on the movable body 5, and the other on the gearbox 16. To prevent collision of the frame 14 during operation of the machine, Boundaries 18, configured to handle fevna 19 minimum diameter. The process of stripping boughs is carried out as follows. Motor 4 and 10 are driven in. Gears 2 and 3 are turned on. Due to the V-belt transmission 9, the additional movable body 8 also rotates with gear 7, and gears 3 and 7 rotate in one direction relative to the axis of the geometric axis. Together with the gear-rotor 3, the movable body 5 attached to it rotates, but the gear 6 drive of the cutting member does not rotate at this moment, since it does not intermix relative to gear 7. Therefore, gears 12 and 13 of bevel gear do not slip. and a milling cutter 14, which rotates only around the geometrical axis of the gears 3 and 7. The milling cutters 14 are in the initial position under the action of the bogies 17. By the feeding device, the barrel 19 is fed into the machine: in the direction indicated by the arrow A. At the moment of appearance of the trunk trunk plane mix audio cutter 14 the engine 10 is turned off and its brake is clamped shaft 11. The pinion 7, together with the movable annular body 8 prekrashaet vrashenie. Gear drive 6 of the cutting organ, run around the fixed toothed rim of gear 7, begins to revolt around its axis. Damage is transmitted to gears 12 and 13 by bevel gearing to a milling cutter 14. Milling cutter 14 with cam 15 at the expense of braking forces in a bevel gear, overcoming the resistance of spring 17, presses against barrel 19, and with further advance of the trunk the bough is cut off by mills 14. The gear can be rotated using the ring movable body 8 of the V-belt transmission 9 and the engine 10 in the direction opposite to the direction of rotation of the gear-rotor 3. The speed of rotation of the cutter around its axis increases, which increases the quality of stripping boughs After processing the entire barrel, the motor 10 is switched to the rotation of the gear 7 in the direction of rotation of the gear-rotor 3 and the milling cutter 14 is returned to its original position by the action of the springs 17. When feeding the next stem, gshkl repeats. Claims. Rotary billet DPN, contains a base, connected by means of a gear with a movable body, which is also by means of. gearing associated with cutting bodies, different in vro, in order to improve quality and productivity, it is equipped with an additional movable housing with a gear wheel, which is associated with gears of the transmission of the cutting organs, the latter being in the form of cutters, and an additional movable The case has an individual reversing drive.
