Description

(5) CONCRETE BALLER

one

The invention relates to devices for the manufacture of concrete and reinforced concrete products.

Concrete pavers are known that contain a self-propelled portal with a feed bin and a vertical vibrating channel turning in a vertical plane to regulate the intensity of concrete outflow from the bunker P.

Also known paver containing mounted on the self-propelled portal swivel dispenser and at least one located above the feed hopper. The dispensing device is made in the form of a receiving funnel, having the ability to rotate in a horizontal plane to evenly distribute the mixture on Form 2.

However, in these pavers, filling the forms with a concrete mixture takes a long time,

WHAT leads to a decrease in performance.

The aim of the invention is to reduce the time it takes to lay a concrete mix in a mold.

This goal is achieved by the fact that in a paver containing a rotary dispenser mounted on a self-propelled portal and at least once a feed hopper placed above it, the dispenser is not. but in the form of a hollow body with inclined diverging nozzles, hinge-; components connected to the latter from receiving and distribution sections, chutes and power cylinders, the power cylinders of the receiving sections being hingedly mounted on the housing, and the distribution sections to the receiving sections.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. 1; FIG. 3 is a section BB in FIG.

The paver consists of a self-propelled gantry 1 moved from drive 2 to 1 {direct it to them 3

Portal 1 has a feed bin mounted on the side walls of which an exciter 5 and a sector shutter 6 are installed, opening from the power cylinder 7 mounted on the side wall of the bunker A dispensing device made in the form of a hollow body 8 rotatable in a horizontal plane with inclined divergent fittings is mounted under the shutter b 9 and 10, as well as articulated gutters, made up of receiving 11 and 12 and distributing 13 and 1 sections. On the housing 8, the power cylinders 15 and 16 are hinged, in turn, by means of the hinges 17 and 18 connected to the receiving sections 11 and 12 and moving them. The hinges 17 and 18 are installed along the bottom of the pipes 9 and 10 and the receiving sections 11 and 12, In turn, the power cylinders 19 and 20 are hinged on the surface of the receiving sections 11 and 12, which control the distribution sections 13 and .1, and these sections They are fitted with sections 11 and 12 of the hinges 21 and 22 along the edges of the grooves.

A housing 8 with nozzles 9 and 10, sections 11-14, and cylinders 15 16, 19, and 20 is rotated by a power cylinder 23 in a frame guide mounted under sector lock 6. The dispenser is equipped with an exciter 25.

The paver works as follows.

Bunker A is loaded with a concrete mixture with the shutter 6 closed and port 1 is installed on the post over the mold 26 for the manufacture of bulky articles 27 Branch pipes 9 and 10 with their sectional grooves 1 l-lt-set to the required position for feeding the concrete mix, for example, in transverse molding sections of mold 26. The shutter 6 is opened, vibration exciters 5 and 25 are turned on, and the mixture from bunker k is fed simultaneously to two molding (transverse) portions of mold 26 through nozzles and troughs. For placing concrete into the longitudinal molding sections of the frame 2 turns When the concrete mixture is loaded with large-sized molds in height, the distribution sections 13 and H can be lifted to a horizontal position and the mixture is fed from the receiving sections 11 and 12. When the forms are loaded with a different arrangement of molding sections in the horizontal plane, section 11- 14 down to

5 of the vertical position and the feed of the mixture is carried out either from both sections simultaneously along each nozzle 9 and 10, or, with the sections 13 and 14 horizontally turned, from

0 receiving sections 11 and 12.

Thus, the proposed paver can speed up the process of filling out forms and increase productivity.
