Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an asphalt mixture transport device that distributes heated asphalt mixture used for road pavement, water works, etc. from a plant factory to a site.

[0002]

[Prior art]

 For small-scale asphalt pavement construction, 200-300 kg of asphalt mix is usually used. Therefore, the heated mixture can be delivered from the plant factory at the site where the transport vehicle approaches. In other words, it is possible to transport the used material from the plant factory on the dump truck by transporting it to the dump truck.Therefore, a heat insulating sheet is laid on the dump truck carrier, and the heated asphalt mixture is placed on the dump truck. They will be transported to the target site while keeping the temperature covered with a sheet from above. At the plant factory, heated asphalt mixture can be put into the truck bed by equipment such as a moving hopper.

[0003] In some cases, heated asphalt mixture is not directly loaded on a dump truck, but is stored in a metal container and transported by truck. The metal container is equipped with a heater on the side surface, and the outside is covered with a heat insulating material, etc., and the temperature of the heater is adjusted with a thermostat. is there.

[0004]

[Problems to be solved by the invention]

 In this way, when an appropriate amount of asphalt mixture is placed on a dump truck, the entire amount is unloaded at the target site at once and the operation starts immediately. However, even when asphalt mixture is released from the loading platform, it may be manually lowered, and the work must be performed during the work while the heat insulation effect is maintained. In addition, when transporting the asphalt mixture from the metal container to the target site in a metal container, the work is complicated by using a dedicated carrying-out device.

[0005] An object of the present invention is to provide an asphalt mixture transport device that can transport asphalt mixture loaded in a plant factory to a target site while maintaining residual heat and easily discharge the asphalt mixture to a pavement site.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the invention of claim 1 is to provide a steel hopper, which can be mounted on a transport vehicle equipped with a generator, with an upper cover provided at an upper opening, a screw conveyor provided at a lower discharge port, and an external device. And a heating device attached to the outer surface of the hopper and the housing of the screw conveyor. Nichrome wires are installed in the hopper and the heating device of the housing, and an electric current is applied to heat and maintain the asphalt mixture.

[0007] The invention of claim 2 is the invention of claim 1, wherein the heating device and the screw conveyor are driven by a facility power supply or a generator of a transport vehicle.

[0008] The invention of claim 3 is the invention of claim 1 or claim 2, wherein the heating device holds the asphalt mixture in the device in a usable state.

According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, a heat insulating member is coated on a housing of the steel hopper and the screw conveyor. The invention according to claim 5 is the invention according to any one of claims 1 to 4, wherein the steel hopper is a pyramid type.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in Fig. 1, Fig. 3 and Fig. 4, the equipment for receiving the heated asphalt mixture at the plant factory and transporting the heated asphalt mixture to the target site is a steel pyramid-shaped hopper 1. The screw conveyor 4 is connected to the discharge port 3 below the hopper 1 substantially horizontally. On the upper surface of the hopper 1, an upper lid 5 having a double-opening structure is provided rotatably upward with respect to a pair of shafts 6 along a pair of frame sides, and a sprocket 7 is attached to each shaft 6. A sprocket 7 'is mounted on a pair of motors 8 mounted on the frame 2, and is connected to the sprocket 7 on the upper lid 5 side by a chain belt 9 to control opening and closing operations of the upper lid 5. If the chain belt 9 is inappropriate, a pulley may be attached using a V-belt.

On the side surface of the hopper 1, a nichrome wire (terminal of a heating device) 10 is mounted while being bent downward from above, and the nichrome wire 10 is mounted on the cylindrical housing 11 of the screw conveyor 4 while being wound. A heat insulating member 12 is attached to the outside of the hopper 1 so as to cover these nichrome wires 11.

The screw conveyor 4 has a sprocket 13 mounted on a shaft protruding outside the cylindrical housing 11 supported by the frame 2, and mounted on a shaft of a drive motor 14 provided on a side of the cylindrical housing 11. The sprocket 13 ′ is connected to the chain belt 15. The rotation direction of the upper lid 5 of the hopper 1 and the discharge direction of the asphalt mixture of the screw conveyor 4 do not interfere with each other, and can be changed to different directions.

As described above, the hopper 1 with the screw conveyor according to the present invention is installed at the asphalt mixture outlet in the plant factory, and the small amount of the heated asphalt mixture that can be unloaded by opening the top lid 5 is provided. Housed in hopper 1. After that, the upper lid 5 is closed by the motor 8 and the inside is closed to be kept warm. At this time, the hopper 1 may be placed on the truck 16 in FIG. 2 or may be lifted by a crane and placed on the truck 16. The hopper can be placed with the discharge port of the screw conveyor facing the side or rear of the truck 16 so that the asphalt mixture can be easily discharged.

When the hopper 1 is placed on the truck 16, a current is applied to the nichrome wire 10 by the generator 17 provided on the truck 16 to heat and keep the hopper 1 and the screw conveyor 4 warm (about 165 ° C.). The generator 17 is a supply source for the pair of motors 8 and the driving motor 14. After arriving at the destination, adjust the outlet of the screw conveyor 4 to the pavement location, or lift the hopper 1 with a crane or the like, check the height and direction, and reinstall it. Then, the screw conveyor 4 is rotated to automatically discharge the asphalt mixture to the pavement.

[0015] The asphalt mixture transport device of the present invention configured as described above has good heat retention and discharge workability, and the usable time (heat retention time) that can maintain the fluidity in which the asphalt mixture can be worked (paved) is determined. Even those that do, transportation work can be performed in a good way. In addition, when a lot of small lots are scattered, for example, a plurality of trucks having a loading capacity of 4t may be transported by loading a plurality of them. The power source for the pair of motors 8 and the drive motor 14 may be a power source at a work site.

[0016]

[Effect of the invention]

 The present invention is as described above. According to the invention of claim 1, a small amount of unheated asphalt mixture which can be unloaded at a plant factory is stored in a steel hopper with a top cover opened, and a transportation vehicle is provided. The asphalt mixture can be heated and kept warm while it is being transported to the target site because it can be kept warm by a heating device via a generator, and the screw conveyor improves discharge workability and allows heated asphalt mixture to be used under favorable conditions. Can be used.

According to the invention of claim 2, since the heating device and the screw conveyor can be driven by the generator of the transport vehicle, pavement work can be performed at a location where the transport vehicle comes close to. According to the third aspect of the present invention, since the asphalt mixture is kept in a usable state by the heating device, pavement work can be performed under favorable conditions. According to the invention of claim 4, since the housing of the steel hopper and the screw conveyor is covered with the heat insulating member, the heating and heat retaining efficiency can be improved. In the invention according to claim 5, since the steel hopper is a pyramid type, the manufacture of the hopper is easy and the hopper is easy to handle.
