Abstract

The invention relates to the manufacture of articles of concrete and reinforced concrete. The purpose of the invention is to increase productivity and ease of use. This is achieved by the fact that in the lower aperture of the lower section 4 of the bunker two oppositely directed vibrolot feeders 9, 10 with a convex-curvilinear inclined working surface are rigidly attached. The lower opening of the lower section 4 is blocked by a segment shutter 12, made in the form of a rotating shaft with a transverse groove. 4 il.

The purpose of the invention is to increase productivity and ease of use,

Figure shows a paver, side view; in Fig „2 - view A see„ „1; on fig.Z - bunker, front view; FIG. 4 is a section BB in FIG. 3.

The paver consists of a self-propelled gantry 1 with a displacement drive 2, on which is mounted a composite bunker consisting of an upper 3 and lower 4 sections and an intermediate element 5 supported by brackets 6 of the upper section 3 on a carriage 7 with a drive 8 moving transversely. In the lower opening of the lower section 4 of the bunker, two oppositely directed vibrating-ground feeders — the main 9 and an additional 10 — are fixed. The lower opening 11 of the lower section 4 is blocked by a segmental shutter 12 made in the form of a shaft with a transverse groove from the actuator 13 fixed on the bracket 14 through chain drive 15 and turning in bearing supports 16 and 17. The side walls of the lower section 4 of the tire holder are connected by a wedge divider 18 having a cross-section in the form of an isosceles triangle.

 Intermediate element 5 to the flanges 19 of the upper section 3 of the hopper and to the flanges 20 of the lower section 4 of the hopper are attached with threaded pairs 21 “A distribution device 22 with a smoothing bar 23, having a smoothing bar 23, is mounted under the lower opening 11 of the lower part 4 of the hopper. the ability of the actuator 24 with the cable-block system 25 to move along the cylindrical guides 26 in the vertical direction

The paver works as follows.

The paver bunker is filled with concrete in any known manner.

The paver is fitted to the mold set at the forming station (not shown).

The actuator 24 is commissioned, as a result of which the distribution

the device 22 and the smoothing bar 23 is lowered onto the form.

Depending on the size of the molded product, the shutter shaft 12 is set to the desired position. The shutter ensures that the lower opening 11 of the lower section 4 of the hopper is closed; opening it at any size; the right window of issue is open, and the left is closed; the left output window is open and the right one is closed; the right window of issue is open completely, and the left one is partially for any value; the left window of the issue is open completely, and the right one is partially by any value; both windows are fully open.

Vibrators of either one section of the hopper or both are put into operation

The drive 8 of the movement of the carriage 7, carrying the hopper with the open bottom opening 11 and operating vibrators, is put into operation. As a result of the shuttle moves of the carriage 7, the distribution device 22 and the form under it are filled to the required capacity.

The drive 2 of the paver paver (gantry 1), the vibrators of the distributor 22 and the smoothing bar 23 are put into operation, as a result of which the concrete mix is laid in the mold, compacted and rough smoothed.

Claims (1)

The invention of the paver, containing on a self-propelled portal a composite bunker in the form of interconnected upper and lower sections closed by an intermediate element of elastic-elastic material with a convex-curvilinear inclined working surface with a vibrating conveyor and a segment gate of sections, a distribution device and a smoothing bar, differing from that, in order to increase productivity and ease of operation, the lower section of the bunker is equipped with an additional vibrating-hole feeder, laid oppositely to the main one and installed along its vertical axis wedge divider, under which the segmented gate is placed.
