(54) DEVICE FOR LAYING CONCRETE MIXTURES

one

The invention relates to the construction of concrete pavements in road and airfield construction.

The road building materials stacker is known, which contains a receiving bunker mounted on the crawler base machine chassis and a frame to which the plate with slide gates is suspended, the guide and arm height, the stacked material layer, the working body with the blade and the vibrating rod 1.

A disadvantage of the known device is the use, as a base machine, of a crawler track gacha, which causes a poor quality of the surface being laid and a high metal intensity of the device.

Closest to the present invention is a device for concrete mixtures, containing a distribution bin on the supporting runners x and a calibrating knife, placed on the rear wall of the bunker G2.

The disadvantages of the known device are the inconvenience of maintenance and insufficient intensity of the processes of forming pavements due to the impossibility of combining the processes of laying and compaction.

The purpose of the invention is ease of maintenance, intensification of the processes of forming pavements by combining the processes of laying and compaction.

This goal is achieved by the fact that a device for laying concrete suites, containing a distribution bunker on supporting runners and a calibrating knife placed on the back wall of the bunker, is provided with spring-loaded "w" position locks of the bunker, a compaction mechanism and horizontal spins in the form of directional oscillatory bodies, installed at an acute angle to the horizon on the front wall of the bunker, which is hinged to the runners, is curved.

Curved skids are made up of pivotally connected upper and lower sections and are equipped with tilt adjustments of the upper section. In addition, the device is equipped

5 additional oscillation pathogen attached to the rear wall of the bunker.

FIG. 1 schematically shows a device for laying concrete

0 mixtures, type; side; in fig. 2 - view

in terms of; in fig. J - section aa, in figure 2.

The device for laying concrete mixes contains a hopper 1 consisting of two side walls 2 and 3, on which, by means of hinges 4, support skids 5 and 6 are installed, and two transverse walls 7 and 8. The back wall 7 of the bunker 1 is made in the form caliber knives with a working edge 9, On sidok 7 and 8 vibration exciters 10 and 11 are installed. Walls 7 and 8 are interconnected by a splicer 12. In the cages 13 and 14 fixed on the rear wall 7 of the bunker 1, spring-loaded latches 15 and 16 are hinged associated with control levers 17 and 18.

Curved support runners 5 and b consist of two halves 19 and 20 connected to one side by a hinge 21. On the top half of the 19 gossips a nut 22 with a screw 23 is fastened, which rests on the bottom half of the 20 runners and serves to change the distance between the supporting surface and the edge 9 of the knife, thereby achieving the adjustment of the thickness of the layer of material being laid. The ends of the pselozevs 5 and b, which are opposite to the hinge 21, end with sleeves 24 with counter holes for the clamps 15 and 16. The rails 5 and 6 are mounted on the guides 25.

The device for laying concrete mixes works as follows.

The concrete mix is loaded into the bunker 1, the exciter 10 is turned on, so that the mixture is evenly distributed throughout the bunker, and the device begins to move along arrow B under the action of the centrifugal forces of the exciter as a result of periodically repeating the phenomena of rolling and pulling the runners 5 and b along the guides 25 at a frequency corresponding to the frequency of rotation of the shaft of the exciter 10. The mixture is evenly laid down and at the same time compacted and smoothed by the working edge 9 of the knife.

The rotation control of the device is carried out by pulling the corresponding latch 15 or 16 from the response holes of the sleeves 24, with the result that the vibration is sufficient to advance one of the supporting

the skids will not be transmitted to it through the hopper 1, the corresponding support skid 5 or 6 will not have progress, i.e. rotates the device. The increase in permeability and adjustment of the gap between the working edge 9 of the knife and the supporting surface or guides 25 is carried out using a nut 22 and a screw 23, changing the height of the working edge 9 of the knife in the plane of the hinge 4

the hopper 1 is suspended. When the exciter 10 is turned off, including the additional exciter 11u, the device is informed of the return stroke, which ensures its maneuverability.
