Abstract

Usage: application of dividing strips on asphalt concrete pavement. SUBSTANCE: machine comprises a hopper with a shield in the lower part, a drive drum located under the hopper discharge opening, a heating device with a bin for storage, connected to the spray chamber. The drum is made with a rectangular-shaped groove located in the middle of its lateral surface and with blades located in the groove, and the spray chamber is in the form of a container connected to the shield located in its upper part at the connection with the shield of the screen located in the lower part of the nozzle container and filtering device. The hopper discharge hole is slit-shaped, and its axis is located in the upper part of the drum with an offset to the side opposite to the rotation of the drum. The lower edge of the shield is placed on a diametrical horizontal plane from the side opposite to the discharge opening of the hopper, and the distribution chamber is mounted under the bottom edge of the shield. 3 ill.

Description

The invention relates to the construction and operation of roads, in particular to devices for applying dividing strips on asphalt concrete pavements.

A working member is known to a road marking machine, comprising a cement distributor with a nozzle mounted on a frame and a stone material distributor with a vibration exciter.

A disadvantage of the device is the impossibility of providing durability and quality of the coating due to chipping of raw material in the cement.

The closest to the proposed technical essence and the achieved result is a machine for applying dividing strips on an asphalt concrete pavement, comprising a distributor in the form of a cylinder with slots, a sector inside it covering the slots, and a cam shaft for pressing marking material from the slots into the coating . The device is equipped with a hopper having a limit shield - dispenser and a coating heater.

A disadvantage of the device is the inability to ensure the durability of the coating due to partial crushing upon indentation of the material and its subsequent ejection due to the lack of adhesion to the asphalt concrete pavement.

The aim of the invention is to increase the longevity of the marking by treating the marking material with binder.

This goal is achieved by the fact that the metered stone material is immediately processed before being laid on the coating together with the coating with a hot solution of polymer binder sprayed with nozzles. To do this, the machine is equipped with a spray chamber connected to a heating device - a heated solution container in chewing; the distribution drive drum is made with a rectangular groove located in the middle part of its lateral surface and with blades placed in the groove; a hopper for stone material is placed above the distribution drive drum, the hopper discharge hole is slit-like, and its axis is located in the upper part of the drum with a shift to the side opposite to the rotation of the drum, the rectangular groove with blades in the front of the drum is covered with a shield, the bottom edge of the shield is placed on a diametrical horizontal plane from the side opposite to the discharge opening of the hopper, the spray chamber is mounted under the bottom edge of the shield and is provided in the bottom parts of it with nozzles and a filtering device.

Figure 1 shows a device of a machine for applying dividing strips on asphalt concrete pavements; in FIG. 2 part of a distribution drive drum with a groove and vanes; in Fig.3 is a diagram of the operation of the spray chamber.

The machine contains a distribution drive drum 1 with a rectangular groove and blades 2 placed in it, closed by a shield 3, a hopper 4 with a slit-shaped discharge hole 5, a spray chamber 6 with nozzles 7 and a filter device 8, a heating device - a tank length 9.

Claims (1)

The machine operates as follows: when the drum 1 rotates, the stone material from the hopper 4 through a slit-like hole 5 enters a rectangular groove with blades 2 in it and moves under the shield 3 into the spray chamber 6, where it is freely poured and processed together with the polymer coating hot in the binder coming from the heating device - binder container 9, nozzles 7 located in the lower part of the spray chamber, and the excess pressure is removed by the filter device 8. Formula of the invention Ma a tire for applying dividing strips to asphalt concrete coatings, comprising a hopper with a shield at the bottom, located above the distribution drive drum, located under the hopper discharge opening, and a heating device, characterized in that, in order to increase the durability of the marking due to processing in the cementitious marking material, it is equipped with a spray chamber connected to the heating device, the heating device is equipped with a binder container, the drum being made with a laid in the middle part of its side surface, a rectangular groove with blades placed in the groove, and the spray chamber - in the form of a container connected to the shield, located in its upper part at the connection with the shield of the screen, located in the lower part of the nozzle tank and filter device , the hopper discharge hole is slit-shaped, and its axis is located in the upper part of the drum with an offset to the side opposite to the rotation of the drum, while the lower edge of the shield is placed on the diametrical horizontal the surface from the side opposite the discharge opening of the hopper, and the distribution chamber is mounted under the lower edge of the shield.
