Description

The utility model relates to road-building equipment and is intended for laying all types of asphalt concrete and bitumen-mineral mixtures on a pre-leveled and compacted base during the construction of roads and airfield coatings.

One of the promising and theoretically substantiated methods for the formation of high-quality roadbed and airfield coatings is a method involving their formation in several layers. To implement these methods, the corresponding self-propelled units have been created.

Known stacker for laying and compacting asphalt pavements (RU 2119002, E01C 19/48, 1998), consisting of two layers. The stacker has two separate buckets, respectively, one conveyor system for the mixture departs from each of them, directed to its dispenser, made in the form of distribution augers.

A device for laying construction mixtures is known (SU 692730, B28B 13/02, 1979), comprising a hopper mounted on the portal with several dispensing windows, each of which has a working body, each subsequent dispensing window and working body are shifted in height relative to the previous one. The device also has a smoothing roller mounted on the console behind the portal, and a drive for moving the device.

A known installation for high-speed construction of hard airfield coatings (RU 2232842. E01C 19/48; B28B 13/02; 2004), containing a frame mounted on a tracked chassis. The main and two additional retractable containers with bins for receiving the working mixture, three sets of working bodies, including devices for moving the mixture, its laying, tamping and smoothing. In addition, the installation provides a power unit and a control unit.

A disadvantage of the known installations is the inability to lay reinforced multilayer coatings.

The closest (prototype) is a device for laying construction mixtures (SU 874369, B28B 13/02, 1981), containing a portal (housing), on the frame of which is mounted a hopper with stepwise arranged transfer windows. The sealing working bodies are mounted with a displacement in height behind the dispensing windows. A portal holder is installed on the portal, consisting of a stop and a bay with reinforcement, over which there is a lid installed in the cavity of the hopper, a fixture for supplying reinforcement and a pressure roller (roller) for final compaction of the working mixture.

The disadvantage of this device is the need to transport it with a tractor, for loading the hopper it is necessary to have a transport system independent or fortified on the portal, for example, a conveyor belt or grab, which impairs its performance.

The technical result is to improve performance and improve the quality of laying.

The technical result is achieved by the fact that the road-forming machine comprising a body, the frame of which is located on the tracked chassis, a hopper with separate cameras, having a conical lower part with transfer windows, a bay holder with stops for the bay with reinforcing material and a feeding device, mounted between dispensing windows, and a packer roller, according to a utility model, the hopper is located on the housing and has gate valves for the dispensing windows mounted on the connector, the machine is equipped with a telescopic -shaped boom mounted on the frame for moving the hopper, in the case, opposite the dispensing windows, guide channels are installed, with a height offset relative to the previous one, belt conveyors for longitudinal transportation of the working mixture are respectively installed under them, and distribution screws for the integral transverse are installed above them the distribution of the mixture on the surface of the conveyors, the machine is equipped with a second telescopic p-shaped boom mounted on the frame at the exit of the stacked canvas, with A packer roller mounted on it, a propulsion system, an operator’s cabin with a control panel, a vibrator drive mounted on a housing under the hopper, which through a connector interacts with the shutter of the transfer windows.

The number of chambers at the bunker, guide channels, conveyor belts and bay holders corresponds to the number of pavement layers.

In FIG. 1 shows a diagram of a machine, a general side view; in FIG. 2 shows the design of the machine during operation.

The machine consists of a housing 1 with a frame 2, supported by caterpillar chassis 3, a hopper 4 with separate chambers 5, having a conical lower part with transfer windows 6 located on the housing 1, bay holders with stops 7 for a bay with reinforcing material 8 and devices 9 ( not shown) for moving reinforcing material 8, mounted inside the housing between the dispensing windows 6, a telescopic U-shaped boom 10 for moving the hopper, mounted on the frame 2. In the housing 1, opposite the dispensing windows 6, guides are installed to shafts 11, with a shift in height relative to the previous one, belt conveyors 12 are installed under them for longitudinal transportation of the working mixture 13, and above them there are distribution screws 14 (not shown) for inseparable transverse distribution of the mixture on the surface of the conveyors 12. The machine is also equipped a second telescopic p-shaped boom 15, mounted on the frame 2 at the exit of the stacked blade 16, with the packer roller 17 mounted on it, the propulsion system 18 and the operator's cab 1 9 with a control panel (not shown in the figure). On the housing 1, under the hopper 4, a vibrator-drive 20 is installed, which through the connector 21 interacts with the gate valves 22 of the transfer windows 6.

The number of chambers at the hopper, respectively, guide channels, conveyor belts and bay holders, depends on the number of layers of the road surface.

The machine operates as follows. Using a telescopic boom 10, the hopper 4 is removed from the housing 1 and mounted on the ground behind the machine. The coils of the reinforcing material 8 using the same boom 10 are installed in the housing 1 on the special stops 7 of the bay holders. Their ends are passed through devices 9 and stacked on conveyor belts 12. The hopper is filled with the working mixture 13 and, using the boom 10, is mounted on the housing 1. A machine with a filled hopper is placed above the place where the mixture is laid. On command from the control panel to the actuator-vibrator 20 using the connector 21 opens the valve 22 and the machine begins to move. The mixture along the guide channels 11 enters the conveyors 12, is distributed on their surfaces by distribution screws 14. When the mixture is difficult to move, the vibrator-drive 20 is turned on. At the exit of the conveyors 12 a roadbed 16 is formed, which is laid on the prepared surface. With the help of the boom 15 pa, the resulting web is lowered to the roller 17, which compacts and finally forms the roadway.
