    In order to effect removal of both limbs and bark from wood, such as trimmings or trees removed in thinning, with satisfactory results in a barking drum, the drum proper comprises a cylindrical pretreatment section of large diameter, a tapering transition section and a cylindrical final treatment section of smaller diameter. In the pretreatment section, which has a larger number of log lifters, an intensive treatment of the bundle takes place, so that the stems of the trees are exposed while branches and twigs are crushed. In the transition section, which has only half the number of log lifters, the tumbling motion of the wood subsides and a change-over takes place to parallel barking, which is concluded in the final treatment section, where the number of log lifters is again increased, suitably up to the original number. The pretreatment section is preferably preceded by an infeed section with infeed means arranged on the inside for quick feeding-in of the bundle of trees into the pretreatment section. The infeed means can consist of helically extending pusher vanes.

    专利说明:

    The invention relates to bark drums and can be used in the woodworking industry.
    A corrosive drum is known, comprising a truncated cone case, on the inner surface of which there are log holders. The discharge side of the drum is provided with slots l.
    Also known is a peeling drum mounted horizontally on rolling bearings, made with open ends and having on the side surface protrusions directed inside the drum to interact with the tree and grooves located between the blisters for removing the wire from the trees, protrusions and slots are located along the 6ar aban axis
    A disadvantage of the known drums is the TOf that they are not intended to remove the spikes from the trees.
    The purpose of the invention is to expand the technological capabilities of the drum by removing branches from the trees.
    The goal is to achieve that the drum has three consecutive sections, the first of which has a diameter larger than the last, and the average is made in the form of a truncated cone whose smaller base is directed toward the last section, and the number of projections of the first and last sections is more than the number of projections of the middle section .
    The number of protrusions of the first section is equal to the number of projections after the section and the middle section has two times less protrusions, and the drum has a device for feeding trees, which is made as an additional section, on the inner surface of which at least one radial blade is fixed, located along the screw lines.
    Fig. 1 shows the proposed pick-up drum, side view in Fig. 2, the same, top view of Fig. 3, section A-A in Fig. 1 in Fig. 4 shows a section BB in FIG. 3. in FIG. 5 is a section B-B in FIG. 1J in FIG. 6 - section G-Y in FIG. 1; in fig. 7 is a section d-d in fig. one.
    The drum-grinding drum contains a horizontally rotating drum I open on both sides and made of thick sheet iron. The drum consists of an inlet section 2 and an unloading section 3, which are separated by an annular gap 4 one or several centimeters wide. Each of the sections of drum 2 and 3 is separately mounted in two pairs of hydrostatic feet with a bearing 5,
    Bearings. 5 abut the base b and act on the support ring 7 attached to the drum 1. In each section of the drum one of the four bearings is a hydrostatic head with an oceBbUJi bearing located on the support ring 7,
    Both sections of drum 2 and 3 are rotated separately by a direct current motor 8 by means of gear 9, which rotates pinned gear 10 attached to the corresponding section of drum.
    5 The striking drum 1 is provided with cuts 11 for bark f; they are located between the longitudinal projections 12 of the log (Figures 5.6 and 7) located on the inner surface of the drum 1 and are made1. Nyeli tilted relative to the protrusions 12 and the axis of rotation of the drum in order to provide increased ao durability and improved unloading of the bark compared to the cuts for the bark,
    J located along the axis. Below each group of slots 11, there is a collection funnel 13 of the plate, supported by the frame 14, the Funnel unloads onto a conveyor, such as a belt cone, a weir 15, to remove the bark. Additionally, there is a tray 16 for feeding the raw material through the inlet of the drum. The bottom of tray 16 at the inlet of the dissolver is slightly lower, i.e. about
    5 by 0.5 m, OCJ1 of the rotation of the drum 1, the open part of the inlet, located below the tray 16 / is covered with a transverse plate 17 so that the feed material does not fall out of the inlet part of the drum.
    Between the inlet and discharge sections, an intermediate section 18 is installed, made in the form of a truncated cone, the smaller of which are directed towards the discharge section. The number of protrusions 12 of the inlet and unloading sections is equal and twice as large as in the intermediate section U1 and 18.
    Drum 1 contains additional
    inlet section 19, located
    before section 2, inside the inlet section is provided with a feeding means 20 for fast feeding of raw materials to section 2. The feeding means 20 contains three
    5 radial blades 21 located along a helical line and attached to the inner side of the additional sections 19 and spaced 120 from each other around the circumference.
    0 The debarking drum re-follows the footprint.
    The raw material binder is supplied .- to the inlet section 2 through the blades 21 of the additional section 19 so that
    Section 2 is always ready to receive.
