    This invention relates to an attachment device for wear rubber elements in barking drums and has as its object simplifying the mounting of such elements by avoiding unnecessary drilling of mounting holes. According to the invention the wear rubber elements are retained at their longitudinal edge sections by mounting bars, for the anchoring of which in the shell plate of the drum bark outlets are utilized.

    2. The device according to claim 1, that is, the fact that the shelves
    - figurative slats are tilted in the direction of the body for exiting the cortex.
    3. The device according to claim 1, which is tactile, in that between the posts of each pair of G-slides of the slats are support plates for limiting the passage of the gaps
    5895
    for the exit of the cortex, the plates being rigidly connected with the G-shaped slats.
    4. The device according to PP. 1 and 3, of which the supporting plates are transversely designed to overlap the fastening elements at the ends of the passage slots.
    This invention relates to devices for fastening wear pads of wear-resistant rubber in a rotating debarking drum and may 6i.iTb be used in the gum industry.
    The debarking drums are known, which contain a housing, the inner of which is located above the top of which the debarders and the longitudinal slits located between them for the release of the cortex 1.
    Also known are devices for fastening 1 blades of wear-resistant rubber in a rotatable debarking drum containing a korggus, on the inner surface of which there are longitudinal debarings and longitudinal slots between the debarking knives | 2
    A disadvantage of the known devices is the low reliability of operation due to the rapid wear of the debarking knives.
    The purpose of the invention is to increase reliability.
    This trick is achieved by the fact that the device has a pair of L-shaped strips arranged symmetrically with respect to the axes of the slits, which are arranged in different directions by their shelves, and fasteners for fastening
    G - obraznyh slats to the drum body, and the rack of these pairs of slats are located at an angle, the top of which is directed to the center of the drum, and each lining has grooves in which the longitudinal bent ends of each of the slats of adjacent pairs are located.
    In addition, the shelves of the L-shaped slats are inclined toward the slots for the exit of the bark, and between the posts of each
    pairs of L-shaped slats are arranged supporting plates for limiting the flow area of the slits for the bark outlet, the supporting plates being rigidly connected with the L-shaped slats and having crossbars for locking the fastening elements at the ends of the slits for the passage of the bark.
    FIG. 1 depicts the wall of the debarking drum lined with wear-resistant rubber, with a device for fastening the linings, a section; in fig. 2 is a view of L in FIG. one; FIG. 3, section BB, FIG. 2
     The proposed device is installed on the inside of the body of the debarking drum 1, which has longitudinal debarking knives 2 and slots 3 located between them for the exit of the cortex. Each knife 2 is provided with an overlay.
    4 of wear-resistant rubber.
    The device for fastening the plates 4 has 3 pairs of L-shaped strips 5 arranged symmetrically with respect to the slits, located in different directions with their files 6, which are tilted js towards the slits 3, and the 7-H-racks are angled, the top of which is directed toward the center of the drum and their end surfaces 8 are supported on the drum body 1.
    Each pad 4 has grooves 9 in which there are bent ends 10 of one of the bars 5 adjacent pairs. Between racks 7 each pair of slats
    5, support plates 11 are arranged, rigidly connected to the latter and having cross-pieces 12 for locking the fasteners, including fastening bolts 13, nuts 14 and washers 15.
    The device works as follows.
    Logs subject to debarking are loaded into the body 1 of the debarking drum. Through the rotation of the drum and the action of debarking knives 2, wood is produced. Since the debarking knives are fitted with pads 4 of wear
    958954
    resistant rubber, durability of debarking knives 2 increases. Due to the fact that the straps 5, which are placed 5 in slots 3 to exit the bark, are used to fasten the pads A, there is no need to drill holes for the fastening bolts in the debarking knives and the drum housing, which increases the reliability of the device.
