This invention relates to a technique for forming precast concrete and reinforced concrete products.

The purpose of the invention is to increase the reliability and reduce the loss of concrete mix.

FIG. 1 shows the proposed paver, side view; in fig. 2 is a view A of FIG. one; in fig. 3 - bunker with a feeder, side view, the dispensing window is closed; in fig. 4 - section BB on

and 23 and tg 24 trays 5 are rotated on hinges 7 downwards, as a result of which the dispensing window of the hopper 3 is opened by the required amount. The vibrators 6 of the troughs 5 are turned on, and the concrete mixture from the hopper 3, which performs the shuttle movements, flows into the tank the vibrating nozzle 29 and from it into the mold across its entire width. When the container is filled, the vibrating nozzle 29 is carried out

FIG. 3; in fig. 5 shows a section B-B in FIG. 3; 10 movement of the paver along the mold, in FIG. 6 — bunker with a feeder, a view of the failure-after laying and compacting the concrete mix, the dispensing window is partially open; The mold is smoothed in FIG. 7 is a view of FIG. 3. The upper open surface of the product with the paver contains the self-propelled help of the tapering device 30. Portal 1 with the movement mechanism 2. Includes the drives 21 in the reverse box 3 with the movement mechanism 4, the shafts 19 rotating in the bearing in the form of two symmetrically to the vertical axis of the bunker of the inclined chutes 5 with a convex-curved working surface and vibration exciters (vibrators) b, the upper end 20 of the hopper window 3, and the stop 25 are con- tured by means of a hinge 7. clocks with the switch 26, which the end walls of the bunker 3. Trays 5 commands the drive 21. are equipped with side vertical walls-In the closed position of the dispensing window 8, which, in turn, are equipped with the bunker 3 elastic seals 9 with elastic seals 9, are attached -band vertical walls 8 of trays 5 with triangular overlays 10 and vertical edges go into tight bolts 11. Triangular overlays 10 have one contact with each other, and horizontal supports 17 and 18 lift nuts 20, while 22 and 23 and the rods 24 trays 5 are pivoted on hinges 7, and are close razdatochvremenno amplifiers lateral vertical walls 8 trays 5.

The lower edges of the side walls of the hopper 3 are provided with elastic seals 12, attached with linings 13 and bolts 14. Elastic seals 15 are attached to the lower edges of the end walls of the hopper 3, always in contact with the convex-curvilinear working surface 30

In close contact with resilient seals 12 attached to the lower edges of the side walls of the hopper 3, resilient seals 16 attached to the lower opposite ends of the trays 5 come into close contact with one another.

Elastic seals 15, attached to the lower edges of the end walls by the bunker trays 5, to the lower opposing pa 3, are always in contact with the ends of which are attached elastic seals with a convex-curvilinear working surface of the trays 5. Thus, when the transfer window of the hopper 3 is closed, its outflow concrete mix

The rotation mechanism of the trays 5 with vibrators 6 is made of two identical parts located on opposite side walls of the hopper 3, each of which consists of a vertical 40 mounted in the bearing supports 17 and 18 of the shaft 19 with the nut 20 and the drive 21 of the rotation of the shaft 19. With the help of hinges 22 and 23 and t g 24 nuts 20. Connected

(cement milk) is excluded. Invention Formula on the ropes 27 of the actuator 28 suspended vibrating nozzles 29 with a smoothing device 30. The paver works as follows. The paver is fitted to the mold (not shown) into which the concrete mix is to be laid. Down during the rotation of which the nuts 20 are lowered, while by means of joints 22 A paver containing a self-propelled gantry mounted on it with buns and trays 5. A ker core is attached to the nut 20 and has a distributor-abutment 25 in the lower part, in contact with the final open window, under which the tel view of two bunker oblique to the axis of the dispensing window 3. Under the bunker there are 3 vibrolotholes with convex curvilinear working surface, hinged on the walls of the hopper, the vibrotraction mechanism CQ with traction and drive, vibrating nozzles with a smoothing device, differ schiys in that with a view to the Enhance reliability and reduction of losses of concrete mixture, the lower edges of hopper side walls 29 are provided uprugiBibronasadok the upper edge 5 of the bead E the seals, vibrating chute - bokovy- form. The drives 21 of the shafts 19 are turned on by vertical walls with seals in contact with the seals of the side walls of the bunker, and the mechanism and 23 and tg 24 trays 5 are rotated on hinges 7 downwards, as a result of which the dispensing window of the hopper 3 is opened by the required amount. The vibrators 6 of the troughs 5 are turned on, and the concrete mixture from the hopper 3, which performs the shuttle movements, flows into the tank the vibrating nozzle 29 and from it into the mold across its entire width. When the container is filled, the vibrating nozzle 29 is carried out Moving the paver along the mold. After laying and compacting the concrete mix in the mold, the upper open surface of the product is smoothed with the help of a taper device 30. Turn the actuators 21 in the reverse direction, the shafts 19, rotate in the bearing window of the hopper 3, and the stop 25 contacts with the switch 26, which gives a command to the drive 21. In the closed position of the dispensing box of the bunker 3, the elastic seals 9 side vertical walls 8 of the trays 5 with vertical faces go into close contact with each other, supports 17 and 18, raise the nuts 20, and by means of the hinges 22 and 23 and the grams 24 the trays 5 turn on the hinges 7 and close the raztora0 In close contact with resilient seals 12 attached to the lower edges of the side walls of the hopper 3, resilient seals 16 attached to the lower opposite ends of the trays 5 come into close contact with one another. Elastic seals 15, attached to the lower edges of the end walls of the bunker (cement milk) is excluded. Invention Formula The rotation of the vibrating channels is made in the form of drive shafts with running nuts vertically mounted in the bearings, each of which is pivotally connected by means of t with the side vertical walls of the vibrating channels, while the shafts are placed on opposite walls of the bunker.
