    The invention relates to forestry and woodworking equipment, in particular to a device for debarking logs in which logs are fused in a rotating drum.
    Known devices for debarking logs include a rotating drum with mechanisms for loading and unloading logs, driving the drum and a device for reciprocating the movement of logs in the drum, made in the form of longitudinal beams LI fixed in the inner surface of the drum.
    However, in these devices, the removal of the bark from the logs is carried out mainly due to the mutual treating of the logs against each other and against the walls of the drum. At the same time, the rotational speed of the drum is limited, since an increase in this speed leads to pressing the logs against the inner surface and virtually eliminates the removal of the bark from them. Low rotation speeds. drum reduce the performance of the device and the quality of debarking in them logs.
    The closest technical solution to the invention is a log debarking device comprising a rotating drum with mechanisms for loading and unloading logs and stationary relative to the drum. longitudinal breaker bar, freely installed in the upper part of the inner cavity of the drum-.
    to on 2.
    In the known device, by introducing a longitudinal breakage beam inside the drum, it is possible to significantly increase the speed of rotation of the drum, which contributes to an increase in the productivity of the device. However, the absence in it of any corrosive tools for striking large amounts of force on the logs leads to a decrease in the efficiency of the debarking of logs, especially logs of various types of trees and of various physical states 25 or of Wood. The introduction of corona-cutting tools for the mechanical destruction of the bark on the logs 9 of the drum increases the loss of wood in the form of sawdust.
    30 The purpose of the invention is to increase the efficiency of log debarking and reduce wood losses. The goal is achieved on the inner surface of the drum by means of annular transverse edges of a radially variable cross section fixed mounting rings with arcuate mounting segments attached to them, spaced between them along the axis of the drum eccentrically with respect to its axis of rotation and relative to each other, moreover, the segment of each installation ring is shifted in the angular direction relative to adjacent segments, placed on the closest to the axis of the drum of the installation ring and provided with a set of deburring tools, made in the form of protrusions with a profiled curvilinear working surface, having a height from 1/50 to 1/100 of the drum diameter, and the longitudinal baffle has a lower working surface inclined to the direction of movement of the logs in the drum at an angle , ensuring the supply of logs to the coring tools mainly in the direction of the radius of the drum. In this case, the protrusions of each installation segment are hemispherical forks and arranged in several rows, and the protrusions of each row are shifted relative to the protrusions of adjacent rows both in the direction of the longitudinal axis of the drum, and in the direction transverse to this axis. In Fig.1 schematically shows a device for debarking logs, side view; figure 2 is a view of And figure 1; on fig.Z - section BB in figure 1; figure 4 is a device, a longitudinal section; FIG. 3 shows a section B-B in FIG. 3 in FIG. 6 b shows the relative position of four adjacent mounting, segments with borer tools; FIG. 7 shows the relative position of the longitudinal baffle beam and mounting rings for placing bore tools, a perspective view; on Fig - the same, end view; Fig. 9 is a view of Fig. 8. The device is an SSD. The elongated rotating drum 1, which is generally horizontal, but may have an inclination downward from the inlet ring 2 in the direction of the exit tip, 3 to improve the passage of the curvatures through the drum. The drum 1 contains an inlet section 4 located adjacent to the inlet end 2 of the drum and a crust-breaking section 5 connected to the inlet section 4. The drum section 4 is made of a solid sheet and is designed to feed the logs into the drum 1. The belt section 5 of the drum is filled from a row of coaxial annular pores b, spaced apart by each other in the longitudinal direction, between which there are 7 slots for the exit of the bark, and the longitudinal channels 8 ,. The supports are located on the outer surface with gaps one from the other and connecting these supports to each other. In another embodiment, the deforming section 5 may be made of annular plates or have a different design, providing the presence of gaps for the release of wood bark. The inlet section 4 of the drum 1 may have, if required, a spiral or other suitable means for improving the flow of the logs through the drum. The drum 1 also contains a pair of annular bandages 9 rigidly fixed on the outer surface of the channels 8 with a gap along the drum 1, and supported by a pair of rotating axle rollers 10 which are in frictional engagement with the bandages 9. The drum 1 is rigidly perpendicular. The gear wheel 11, which is engaged with the single-wheel gear 12 and rotated by the motor 13, which is connected to the gear wheel 12 via the reduction gear 14. The motor 13 is selected so as to rotate the drum 1 loaded with logs with a relatively high rotational speed in the range of, for example, from 20 to; 100 rpm. The direction of rotation of the drum in the proposed design of the device is taken counter-clockwise. In another embodiment, the drum 1 can be supported and rotated in a different way with the above-mentioned relatively high speed of rotation. The device also contains fixed or non-rotating sections for loading 15 and for unloading 16 logs adjacent respectively to input 2 and output 3 ends of drum 1. Stationary section 15 for loading logs is installed using a support stand 17 and contains a feed chamber 18, one open horse of which It is provided with an internal cavity of the inlet section 4 of the reel for feeding the unrolled logs into this input section. The other end of the feed chamber 18 has a reduced cross section and is connected through a relatively small diameter inlet-19 to the conveyor 20 or another log feeding mechanism 21 to be debarched. The feed chamber 18 gradually increases in cross section to a full cross section of the internal cavity of the drum inlet section 4 in the direction from the inlet 19 to the inlet section 4.
    The stationary section 16 is installed using a support post 22 and comprises a discharging KaNjepy 23, one open end of which is connected. with the internal cavity of the output end 3 of the drum for unloading of peeled logs from the drum. The unloading chamber 23 contains a part gradually tapering in cross section in the direction of the other end, at which the unloading chamber ends with a relatively small outlet opening 24 connecting to the exit chute 25 intended for unloading logs 26 of 1 amber 23. sections 15 and 16 can be mounted on the drum 1 and rotated with it.
    The drum cutting section 5 is provided with relatively blunt cutting tools 27, designed to apply high intensity hammer-like shocks to logs passing through the cleaning section 5 during a relatively high rotation speed of the drum 1. The cleaning tools 27 are used to debar logs and also cause rotation of the logs and their lateral movement, with the result that different parts of the logs come into contact with the tools 27 many times.
    The configuration of the debris tooling 27 is hemispherical protrusions that have arched outlines on all working sides to minimize wood damage and that are small enough to provide high pressure and local strikes on the logs during the bark removal operation. For example, the arcuate work surface 28 of each tool 27 may have a radius of from 1/50 to 1/100 of the diameter of the drum 1.
    Blowing tools 27 may also have a different hemispherical configuration, in which the dimensions of the tools along drum 1 remain relatively small, with the result that they can provide the specified high pressure and strike the logs. The stripping tool 27 can be of different sizes and can be located at different places on the drum. 1. For example, the tools 27 adjacent to the inlet section 4 of the drum 1 may be smaller, other tools that gradually increase in size. D of the inlet section of the drum 4 towards the outlet end of the drum 3.
    The debarking tools 27 are installed so as to apply random strokes to the logs passing through the drum 1, and also to peel the hollow parts or valleys of the logs, in particular, an eccentric annular mounting plate (edge) 29 with a cross-section continuously changing in the radial direction, attached outer / surface to the inner surface
    10 of the corresponding annular support 6. In addition, adjacent mounting plates 29 are displaced along the axis of the drum 1 in the angular direction, with the result that most parts
    15 contiguous plates 28 having an increase in cross section in the radial direction run along an arc along successive arc segments of the drum circumference and redo small portions of their
    20 lengths ..
    To the inner surface of each mounting plate 29 is attached a mounting ring 30 for tools, separated by a gap 31 from
    5 of each adjacent ring, and each installation ring 30 for tools, in turn, has an arcuate Installation segment 32 for tools, shown (with a view to
    0 illustration) with an angular size of about 100, which is located so that. runs along part 33 having the largest size in the radial direction .. of the corresponding mounting plate 29. On each of the tool segments 32 there is a set of debris tools which contains several rows of tools 27 passing around the circumference, with the rows of each tool set 27 are offset relative to each other along the longitudinal axis of the drum 1.
    In another embodiment, the design tools 27 each set can
    5 to be arranged in a different order, for example, peripheral adjacent rows of instruments may be displaced in the longitudinal direction of the drum 1, as well as each set of instruments 27,
    0 if required, can be set-. flax in a spiral.
    The proposed location of the installation segments 32 for tools ensures the passage of adjacent
    5 segments in an arc along successive arc segments of the inner surface of the drum and in the longitudinal direction overlapping an insignificant part of their angular distance.
