    A pair of cleat forming wheels are journalled within a frame on each side of the packing chamber of an extruding type slab forming machine, to produce shear keyway recesses in the side walls of the slab as it is formed. The wheels are connected together for rotation in the same direction by an idler gear or chain sprocket connection. The teeth on the rear or following wheel are slightly smaller than the teeth on the leading or forming wheel so that the teeth on the rear wheel finish off the forming of the recesses without damaging same. Automatic self-alignment of the teeth of the rear wheel with the recesses is provided by an adjustable slip clutch between the rear wheel and the drive connection from the leading wheel.

    (54) EXTRUDER
    one
    The invention relates to the manufacture of extruded boards, and specifically to devices for forming grooves on the side surfaces of extruded plates.
    A extruder is known that contains a self-propelled frame on which a loading hopper is mounted and a Kc1mer molding located under it, in the side walls of which there is a pair of symmetrically spaced relative to the longitudinal axis of the chamber of pazoobraznye gear wheels 1.
    The aim of the invention is to increase the efficiency of the extruder.
    This is achieved by the fact that an extruder containing a self-propelled frame on which a feed hopper is mounted and a rear chamber located beneath it, in the side walls of which a pair of pazoobraznyi gears are arranged symmetrically relative to the longitudinal axis of the chamber, each equipped with a pair of calibrating gears mounted in series with the Pazoobraznye wheel and connected to it by means of a synchronizing transmission, which is made in the form of Pazoobrazuyu and ka2
    Driving gear wheels connected between an intermediate gear. In addition, the synchronizing gear is made chain, and its sprockets are fixed respectively on the shafts of the pausing and calibrating wheels, the synchronizing gear being fitted with a safety friction clutch mounted on the calibrating wheel.
    FIG. 1 schematically shows an extruder, a general view; FIG. 2 shows the installation of a groove tool; in fig. 3 is a plan view of FIG. 2 with a synchronous gear; in fig. 4 is a plan view of FIG. 2 with synchronizing chain transmission; in fig. 5 is a plan view of FIG. 2 - with a safety friction clutch.

    The device consists of a self-propelled frame 1 with a loading 1 1 block 2, under which is placed a single chamber 3. On the self-propelled frame 1 there are fixed vibrators. In the side walls of the frame 1 there are symmetrical windows 4 to which grooves are attached, each of which is made in V1 and ducts 5 in which gears 6 and 7 connected in pairs by a synchronizing gear are placed, one of which (wheel 6) forms keyways, and another (wheel 7) - calibrates. The synchronizing gear of gears b and 7 can be made in the form of gears 8 and 9 interconnected by intermediate gear 10 or chain, sprockets 11 and 12 of which are fixed on wheels b and 7 and are connected to each other by a chain 13. Calibrating gear wheel 7 can be equipped with a safety friction clutch 14. The device operates as follows l. The concrete mixture from the hopper 1 under the action of its own weight enters the forming chamber, 3. In the chamber under the action of vibrators and augers (conventionally not shown in the drawing) the mixture is molded and compacted. Due to the reactive force generated by the augers of the concrete mixture, the extruder moves in the opposite direction, leaving behind a molded concrete strip. Unvibrated backs of the core and upper plate smooth down the molded surfaces of the product. The pressing pressure on the concrete mix is determined by the frictional forces that occur between the concrete and the moving extrusion extrusion bodies, as well as the resistance to movement of the machine itself. Claims 1. An extruder comprising a self-propelled frame on which are mounted a cargo bunker and a shape / under chamber located under it, in the side walls of which there is a pair of symmetrically positioned gear wheels relative to the longitudinal axis of the chamber, characterized in that efficiency, it is equipped with a pair of calibrating gear wheels, each of which is installed in series with the paver-forming wheel and connected to it by means of a synchronizing transmission.
    [2]
    2. An extruder according to Claim 1, characterized in that the synchronizing transmission is made in the form of a pazoobrazuyushchaya ikalibiruyuschey wheels fixed on the shafts, connected by an intermediate gear.
    [3]
    3. The extruder according to claim 1, wherein the synchronizing transmission is made of a chain, and its sprockets are fixed respectively on the shafts of the pazoobrazuyuschego and calibrated wheels.
    [4]
    4. The extruder according to claim 1, wherein the synchronizing gear is provided with a safety friction clutch mounted on a calibrating wheel. Sources of information taken into account in the examination 1. Finnish patent number 53410, cl. In 28 In 3/20, published. 1975. 7 3
