SUMMARY OF THE INVENTION: The funnel has power cylinders pivotally mounted on its side walls and two-arm levers pivotally connected to the rods of the power cylinders, the free ends of which are rigidly connected to the leveling blade, and the lower part of the funnel is made of a cylindrical shape with a height exceeding the thickness of the upper layer stacked mixture. 7 ill.

Description

The invention relates to the molding of precast and reinforced concrete products.

Mzeieten batoio / clutch containing a self-propelled carriage traveling along crane tracks, a self-propelled carriage carrying a hopper with a dividing wall m that rotates around a vertical osm and has two outlet funnels equipped with gates. A leveling blade is installed between the hopper funnels of the bunker.

The disadvantages of the known paver include the lack of a working body for laying the concrete mixture into the mold (vibrating nozzle, funnel), which excludes the possibility of laying the concrete mixture over the mold area, especially if there is no feeder at the hopper. When the sector gate is opened, the concrete mixture will flow out of the hopper and slide down on the pallet of the mold and beyond; the absence of a portal excludes the possibility of using a paver at concrete plants, since the crane runways are located at a height

several meters, and the molding surface does not exceed a height of 0.8 m; when leveling the concrete mixture, the lower hinge of the leveling blade will always be in the concrete mixture, excluding the performance of the paver; the difficulty of filling the separator wall hopper with various concrete mixtures. Both concrete sections will always deliver both concrete mixes, excluding dosing attempts. The design of the hopper and leveling vanes precludes the use of a paver for forming products with window and door openings, i.e. the paver is not suitable for forming products in precast plants.

The aim of the invention is to remedy these disadvantages, i.e. enabling multilayer molding. products with openings and without openings,

This goal is achieved by the fact that the paver containing a self-propelled frame, the carriage with a feed hopper,

a funnel with a drive of its rotation around the vertical axis and sherly mounted on the leveling blade, the funnel is equipped with power cylinders pivotally mounted on its side walls and two-arm levers pivotally connected to the rods of the power cylinders, the free ends of which are rigidly connected to the leveling blade, and the lower part has a cylindrical shape with a height exceeding the thickness of the upper layer of the stacked mixture.

Figure 1 shows a paver, side view, a variant with one hopper; figure 2 is the same, an option with two bins; Fig. 3 - a hopper with a feeder, a funnel, a leveling vane in the laying position of the lower layer of the mixture; figure 4 is the same when laying the mixture in the form with a window opening; figure 5 is a view along arrow a in figure 4; Fig. 6 shows a hopper with a feeder, a funnel, a leveling vane in the laying position of the middle layer of the mixture; Fig. 7 is the same when laying the upper layer of the mixture.

The paver contains a self-propelled frame 1 with a movement drive 2, a carriage 3 with a movement drive 4, moving along the upper platform of the self-propelled frame 1 and carrying a hopper 5 (or two hoppers 5) with a feeder 6. A pantograph is suspended from the carriage 3 using levers 7 of the type Ricks 8, with the ability to rise and fall from the winch type drive 9 and rotate around a vertical axis from the drive 10, The lower part of the funnel 8 has a cylindrical shape with a height exceeding the thickness of the upper layer of the stacked mixture. On both sides of the funnel 8, two shoulders 12 are attached to the hinges 11, to the short shoulders of which the rods of the power cylinders 13 are pivotally attached to the side walls of the funnel 8. To the long shoulders of the two shoulders of the levers 12 the leveling blade 14. The shape is indicated by 15. .

The paver works as follows.

Hopper 5 (hopper 5) is loaded with concrete mixture.

Drive 2 is turned on and the paver is fitted to mold 15 into which the mixture is to be laid.

The power cylinders 13 are turned on to turn the two-arm levers 12 with the leveling blade 14 into the working position, when these shoulders of the two-arm levers occupy a vertical position.

Drive 9 is turned on and funnel 8 on levers 7 is lowered down to

the position when the lower edge of the leveling vane 14 is at the desired distance from the mirror of the pallet form 15. Turn on the feeder 6 hopper

5 and at the same time either drive 2 of the self-propelled frame 1 (when laying the mixture with a longitudinal strip), or drive 4 of the carriage 3 (when laying the mixture with a transverse strip). If the width of the mold section into which the mixture of the leveling vane 14 is to be laid, the drive 10 of turning the funnel 8 is turned on and the funnel 8 is rotated to such a position that the leveling vane 14 takes a diagonal position

(see figure 5).

Through the shuttle strokes of the leveling vane 14 with the feeder 6 operating, the mixture is laid in an even layer over the entire area of the mold 15.

If the paver is single hopper,

then after laying the first (lower) layer

mixtures, hopper 5 is empty

and it should be loaded with another mixture.

If the paver is two-hopper, then laying the second (middle) layer of the mixture is carried out from the second hopper 5. To do this, turn on the drive 9 and the funnel 8 is raised to the desired level, and the leveling blade 14 using the power cylinders 13 is turned into the original (horizontal) position, after which the laying of the second (middle) layer of the mixture is carried out in the order described above. The walls of the funnel 8, having a bottom cylindrical shape to a height exceeding the thickness of the upper layer of the stacked mixture, allow a more accurate installation of the funnel 8 from the sides of the mold 15, which ensures a more accurate laying of the mixture.

By activating the drive 9, the funnel 8 is raised to the level of the upper edges of the sides of the mold 15 and the top layer of the mixture is laid in the order described above, after which the paver cycle ends.
