    A pump assembly has a hopper adapted to hold a wet concrete mass and having a front wall formed with a front port centered on a front axis perpendicular to the front wall at the front port and a rear wall formed with two rear ports centered on respective rear axes perpendicular to the rear wall at the rear ports and generally parallel to the front axis. Respective piston pumps secured to the rear wall outside the hopper over the rear ports are operable to draw portions of the mass out of the hopper and expel them back into the hopper through the respective rear ports. An outlet conduit is connected to the front wall outside the hopper over the front port and a distributor pipe in the hopper has a front end fitted and aligned with the front port and a rear end engageable over and alignable with either of the rear ports. A buttress formation fixed on front end of the distributor pipe defines outside the hopper a buttress plane parallel to the front and rear planes. An abutment lying on the buttress plane engages the buttress formation. A drive oscillates the distributor pipe about the front axis between one position with the rear end aligned with and engaged over one of the rear ports and with the other rear port opening into the hopper and another position with the rear end aligned with and engaged over the other rear port and with the one rear port opening into the hopper. The buttress formation and abutment remain in contact with each other but move relative to each other parallel to the planes as the pipe moves between the positions. Tie rods anchored in the abutment and in the rear wall prevent forward movement of the pipe and thereby press the rear end against the rear wall.

    The invention relates to the transport of slurries, and specifically to a device for transporting porridge-like viscous masses.
    The purpose of the invention is to increase reliability.
    In FIG. 1, there is shown a transport device, a longitudinal section in FIG. 2, view A in FIG. 1,
    The device contains a pump consisting of at least two pistons 1 arranged in cylinders 2 arranged parallel to each other, a hopper 3 with two openings in its front along the mass transfer wall 4, filled in one nrfor- bone coaxially to cylinders 2,
    The device also contains a distribution pipe 5 for alternately connecting the openings with the pressure pipeline 6, mounted obliquely in the hopper 3 and mounted on its rear wall 7 with the help of the fold 8 with the possibility of rotation, and on the wall 4 with the lever 9 mounted on a rotary shaft 10 mounted symmetrically to cylinders 2 and coaxially with the axis of rotation of the nozzle 5 in the front wall 4. A flange 1I mounted to the water pipe b is connected to the flange 8 made with a vent located outside the rear wall 7 with entering the zone opposite cylinders 2 and extending in a direction parallel to them.
    In addition, the device is equipped with a counter support 12 for supporting the portions of the protrusion in the zone opposite the cylinders 2, made in the form of a plate, vertically located on the side of the protrusion opposite to the bunker 3, and illuminated on the straps 13 fixed to the wall 4, plate 14, and on the ledge fixed clamping plate I 5,
    The straps 13 are threaded at their ends, with stops 16 and intermediate sheets (not shown) to compensate for wear in the plane of rotation of the nozzle 5, which are mounted so that they can move along the threaded sections.
    The device works as follows.
    When pushing concrete out of cylinder 2 into pipe 5 and further into pipeline 6 in the zone located on the

    due to the cylinder 2, force, protin (acting on the direction, which due to the geometrically closed structure is transmitted to the offense,
    Preferably, the proposed device is to reduce wear due to the fact that the support moves outside the bunker, and the forces expended in moving the distribution pipe are reduced by reducing friction.

    Claims (5)
    [1]
    1. A device for transporting viscous viscous masses, mainly concrete, containing a pump with at least two pistons located in cylinders mounted parallel to each other, a bunker with two openings in its front in the course of mass movement in the same plane coaxially to the cylinders, a distribution nozzle for alternately connecting the holes with the pressure pipe, mounted obliquely in the bunker, mounted on its rear wall With the help of a flange, can be rotated, and Radney - using a lever mounted on a rotary shaft, mounted symmetrically to cylinders and coaxially with the axis of rotation of the distribution pipe in the front wall, and mounted on the pressure pipe flange connected to the flange of the distribution pipe, characterized in that, in order to increase reliability, the flange of the distribution pipe at the place of its connection with the flange of the discharge pipe, is made with a protrusion located outside the wall of the bunker
    entering the zone opposite the cylinders and extending in a direction parallel to them, and the device is equipped with a counter support for supporting parts of the protrusion in the zone opposite the pump cylinders, made in the form of a plate, vertically located on the outlet side opposite to the bunker, attached to its front wall,
    [2]
    2. The device according to Clause D, which is provided with a base plate fixed to the counter support plate,
    [3]
    3. The device according to claim 2, characterized in that it is provided
    a pressure plate fixed on the protrusion for engagement with the support plate.
    [4]
    4. The device according to p. 3.0 aphids is such that the splices are threaded at their ends, stops for the counter support plate on the threaded sections and intermediate sheets to compensate for wear in the plane of rotation of the distribution pipe.
    [5]
    5. The device according to claim 5, about tl and. This is due to the fact that the intermediate sheets are mounted on, stretching with the possibility of movement along the threaded sections.
