(54) PORTABLE MECHANIZED DEVICE FOR REMOVING THE CRUST FROM TREES

The device relates to mechanized tools used in forestry, for example, for killing trees in planted forests by removing annular areas of bark. A portable mechanized device for removing bark from trees is known, which includes a housing, an annular rotor with push-on cutters attached to it, a rotor drive and a prytry mechanism. Such a device cannot be used to cut the bark of growing trees; moreover, since the cutting elements of the device are not closed, it is dangerous to use. The purpose of the invention is to ensure the possibility of removing bark from growing trees and to ensure safety in work. For this purpose, sector cuts with a vertex angle of up to 10 ° are formed in the device case and the annular rotor, and the centering wheel is defined as two diaphragms installed in the case on both sides of the rotor with hinged arms attached to the case and cutters in the process of the device. FIG. 1 shows a device with a closed centering device, top view, on. 2 - the same, without a centering device,. The working part of the device consists of two cutting cutters 1 with teeth 5 transversely cut, which are fixed hinged to the rotor 2 and rotating with it, due to the presence of the gear ring 3. The rotor 2 receives a circular rotational movement from the screw 4 on the drive shaft 5. Through the bevel gears 6 and 7 from the drive shaft the helical helper receives rotation. non-driving roller 8 with i worm 9. From drive 10, through bevel gears and worm rollers, the movement is transmitted to a rotor, freely placed in roller bearings, on which the hinges of the cutters with springs 11 are fixed. two diaphragms that are controlled by a iiiapHHpHO attached to the body in sniper 12. A device for stopping the poiopa in the form of a stopper is located in the lower part of the body (on the hell, not shown) ,; and on the handle 13, it is controlled by j inie. flycK and stop the rotor by K1TSY turning on or vychyucheniem drive (eg electric motor) .; The device operates as follows. The lever 12 is retracted to the leftmost i position (the initial position of the rotor i is shown in Fig. 2). The HO-I device is then given forward until the incisors 1 touch; with the barrel 14, after which the lever 12 returns to the right and depending on the diameter of the diaphragm center the device relative to the barrel 14. When the drive is turned on, the rotor receives rotation, cutters 1; around the circumference cut the bark. Through 3-. j5 juice the drive is disconnected, the stopper stops the rotor in the initial position, the lever 12 is retracted to the left, the diaphragm lays out 1- the trunk 14, the device is retracted from the tree to the worker, which passes to the new tree. The cycle of operation is repeated. t I 1 subject of the invention j | j A portable mechanized device I for removing bark from trees, comprising: a housing, an annular rotor with a hinge; mounted on it a spring-loaded cutter, a rotor drive and centering mechanism, characterized in that, in order to provide the possibility of removal; bark from growing trees and increased safety of work, in the device case and j annular rotor sector I slots are formed with an apex angle of up to 100 °, and the centering mechanism is completed as two diaphragms controlled by a hinge | to the body with a lever and a rotor with a cutter in the process of a j6oTbi device.
