FIG. 2; in fig. 5 is a section of YYD in FIG. 4, in FIG. 6 - bunker with closed aperture, side view; in fig. 7- node I in FIG. 6; FIG. 8 shows a bunker with an open opening, side view; FIG. 9 is a view of D in FIG. 6

The paver includes a self-propelled gantry 1 with a movement mechanism 2.

The vertical movement of the hopper 5 with the vibrating nozzle 23 is made in the form of two opposedly and hingedly mounted on carriages 3 power cylinders 24, the rods of which are fixed on racks 18 by means of hinges 25 and brackets 26, to the carriage 3, vertical IQ guides 27, in contact with the rollers 28 and 29 with vibration-insulating cladding 30 and 31, attached to the bunker 5 by means of hinge brackets 32 and 33. Each vibro-15 tray is equipped with an oscillation pathogen 34, and the vibro-nozzles - an oscillating pathogen 35

The paver works as follows.

The mechanism 2 is turned on. The movement of the self-propelled gantry 1 and the concrete paver is fitted to the mold in which the product is to be molded. After that, the movement mechanism 2 of the portal 1 is turned off. Then, with the help of power cylinders 24, a hopper 5 with a vibrating nozzle 23 is lowered along the guides 27 along the upper edges of the mold, after which the power cylinders turn on

on which a driven carriage 3 is mounted with its movement mechanism 4 and a bunker 5, in the lower part of which there is a feeder in the form of vibrolot 6 installed symmetrically to the vertical axis of the bunker, having a convex-curvilinear working surface. Vibrating rods 6 by means of a hinge 7. mounted on the wall of the hopper 5, the lower edges of which have elastic-elastic seals 8, which are in contact with the working zone 12 with their pistons moving downwards, in the surface of the vibro-trays 6. as a result

On the side walls of the bunker 5 cm-shafts 10 fixing devices

The drive of vertical movements of the hopper 5 with vibrating nozzle 23 is made: in the form of two opposed and hingedly mounted on carriages 3 power cylinders 24, the rods of which are fixed by means of hinges 25 and brackets 26 on racks 18. The carriage 3 is attached to vertical guides 27, in contact with the rollers 28 and 29 with vibration-insulating cladding 30 and 31, attached to the bunker 5 by means of hinge brackets 32 and 33. Each vibratory tray is equipped with an oscillation pathogen 34, and the vibro-nozzles - an exciter of oscillation 35

The paver works as follows.

The mechanism 2 is turned on. The movement of the self-propelled gantry 1 and the concrete paver is fitted to the mold in which the product is to be molded. After that, the movement mechanism 2 of the portal 1 is turned off. Then, with the help of power cylinders 24, a hopper 5 with a vibrating nozzle 23 is lowered along the guides 27 along the upper edges of the mold, after which the power cylinders turn on

12 with their pistons moving downwards, as a result of which a turn occurs

The fixing device is eliminated, which excludes the impact of dynamic loads on the feeder when the bunker is filled with 5 with a concrete mixture. The fixing device is made in the form of eccentrics 9 in contact with the outer surface of vibrating channels and mounted on slotted shafts 10 mounted on brackets 11 fixed to the side walls of the bunker 5. Each an eccentric 9 is associated with a drive of vertical movements of the vibrating chutes 6 in the form of a ram 12 fixed by means of a hinge 13 on the side wall of the hopper 15. The links 14 are rigidly fixed on the rods of the sylivol cylinder 12, to which vibrolot 6 is attached by means of the articulated levers 13, One of the links 16 of the articulated levers 15 is mounted on the shaft 10 with the possibility of permutation by melkoshlitsevnogo fit 17. With the bunker 5 is connected by vertical racks 18 with hinges 19 and elastic elastic elements 20, 21 and 22 vibrating nozzles 23.

with eccentrics 9 in contact with the outer surface of the vibrating rods 6. Since during the piston stroke of the cylinders 12 downward, the shafts 10 with the eccentrics 9 rotate in the direction excluding the jamming of the vibrating grooves 6, the latter turning on their own weight and mass on them hinges 7 and open the lower opening of the hopper 5 to the desired value. The oscillations exciters 34 of vibrotrays 6 are turned on, and the concrete mixture located in the bunker flows into the tank of the vibrating nozzle 23, and from there into the mold. Then, the vibration exciter 35 is switched on the vibrating nozzle 23 and the mechanism 2 for the movement of the portal 1 and the concrete mixture is placed into the mold with its simultaneous compaction.

When several products are molded in the form or one wider product, when the opposite end of the form is reached, the portal movement mechanism 2 and the exciters 34 and 35 oscillations are turned off, and the trolley 3 movement mechanism 4 is switched on and the vibrating nozzles 23 are adjusted to the next form compartment, the trolley 3 stop, include pathogens 34 and 35 oscillations and move the portal 1 in the opposite direction, laying and compacted while the concrete mixture of the second compartment and.

After the concrete mixture is filled and compacted in its entire form, the paver operation ends.

Power cylinders 12 are activated with the movement of their elements upwards, and the attached to their connecting rods 14 and the hinge-J5 of the ticking axis of the vibrolotholes are raised upwards

The levers 15, one link 16 of which is mounted on the shaft 10. As a result, the shafts 10 are rotated in the brackets 11 and the eccentrics 9 occupy a position at which their generators 10 most distant from the axis of rotation of the shaft 10 are in contact with the vibrating channels 6, which ensures their rotation to the closed position when the lower opening of the bunker 5 is tightly closed. In this position, the vibrotracks 6 when loading the hopper 5 with concrete mix the dynamic load on the power cylinders 12
