Description

The present invention relates to a garbage storage device used for storing and transporting garbage.

[Conventional technology]

In recent years, the distance from a residential area or the like to a garbage disposal site has increased, and a method of collecting garbage by reciprocating a large number of garbage trucks during that time has the disadvantage of lowering collection efficiency and causing traffic congestion and the like.

A typical means for dealing with such inconvenience is a garbage storage device for temporarily storing garbage from a general household such as a residential area or an apartment complex, and transferring the collected garbage to a garbage truck when the garbage becomes full. Is installed at a predetermined position.

As one example of such a dust storage device, as shown in FIG. 10, a dust storage drum having a spiral blade 42 on the inner peripheral surface thereof
The storage drum 41 is rotatably supported on a gantry 43, and an input port 44 is provided on the rear surface of the storage drum 41, and a discharge port 45 which is opened and closed by a door 46 on the front surface.
Some of the storage drums 41 are provided with a garbage carrying conveyor 47 slidably forward and backward below the storage drum 41.

In this device, when dust is thrown in from the inlet 44, the dust is compressed and stored on the front surface of the drum by the feeding action of the spiral blade 42 which rotates the storage drum 41. Then, when the garbage is full, the drawn-out conveyor 47 is inserted into the garbage truck 48, and the storage drum 41 is rotated to discharge the garbage from the discharge port 45.

[Problems to be solved by the invention]

By the way, this storage device is installed at a predetermined position, but if the storage device is to be loaded on a traveling vehicle and transported, the mounting position of the unloading conveyor 47 is the highest in the garbage truck. Since the height of the gantry 43 is set so as to match the dust receiving port, there is a problem that the center of gravity when loaded on a traveling vehicle is significantly increased, and it is difficult to transport the vehicle.

On the other hand, when the garbage temporarily stored in the above-mentioned conventional storage device is collected by a garbage truck, the garbage collected by the garbage truck is transferred to a large truck, and the trash is transported to the final disposal site by the truck. It is possible to envision a collection method of doing so.

However, in such a collection method, the conventional garbage truck uses a method of flipping the tailgate of the rear door upward, dumping the garbage collection box and discharging the garbage, so When transferring garbage directly to a large OB van, the tailgate interferes and the garbage truck's discharge position is lower than the large OB van's receiving position. For this reason, it is necessary to take a method of transferring garbage by discharging garbage from the garbage truck and transporting the garbage to the relay truck by using a transport conveyor device or the like.

However, a large space is required at the relay location where such trash is transferred, so it is difficult to secure that location near the residential area, and the odor of the garbage discharged from the garbage trucks causes There are drawbacks that hinder the environment. Therefore, when such a collection method is adopted, a method in which the tailgate of the garbage truck does not interfere with the large OB van and the discharge position is not lower than the receiving position of the large OB van, and no transport conveyor device is provided. It is necessary to

In addition, if the garbage storage device is loaded on a traveling vehicle without being transferred to a relay truck and transported to a garbage disposal site, and the garbage is discharged directly from the storage drum 41 to a garbage disposal site or the like,
Simply discharging from the discharge port 45 using the feed of the spiral blade 42 has the disadvantage that the discharging speed is slower and the discharging efficiency is lower than in the dump system.

Therefore, an object of the present invention is to provide a garbage storage device that enables a garbage collection / transportation, a dump-type garbage discharge, and a garbage transfer to a large OB van selectively while being attached to a traveling vehicle. is there.

[Means for Solving the Problems] To solve the above problems, the present invention rotatably supports a dust storage drum having a spiral blade on an inner peripheral surface on a gantry, and has an opening on a rear surface of the storage drum. The front door has an openable / closable door, and the rear door has an inlet and a lid attached.The pedestal has foldable and height-adjustable legs and a horizontal or inclined mount on the vehicle platform. Installation section, and a discharge conveyor is provided under the discharge port so as to be able to be drawn out to the outside so that the garbage discharged on the road surface can be sent out to the relay vehicle. The garbage storage device is configured to selectively perform dump discharge and garbage transfer to the relay truck.

[Action]

The garbage storage device of the present invention having the above-described configuration is capable of transferring garbage to a place where a large garbage truck stands by a conventional small garbage truck and a large OB van and directly moving many garbage trucks to the final disposal site. Even if it is possible to prevent lowering of garbage collection efficiency and traffic congestion, another inconvenience that may occur due to changing the transportation method can be expected. It is designed as a core device of a system for improving traffic and preventing traffic congestion.

When the garbage storage device of the present invention is installed at a predetermined position and becomes full of garbage, the garbage storage device is loaded on a traveling vehicle and transferred to a place where a large OB van waits, where the garbage storage device is unloaded. It is used to transfer garbage directly to a large OB van by connecting it to a large OB van so that trash can be transferred.

When loading and transporting on a traveling vehicle, the legs are folded down, the height of the gantry is reduced, and the mounting portion is mounted on the traveling vehicle to transport. If you want to transfer the garbage to the large truck in the waiting area of the large truck, set the legs vertically and adjust the height of the gantry high to set the discharge port on the front of the storage drum into the large truck. Fit to mouth. Then, the connection is made so that the conveyer can be pulled out and the refuse can be introduced into the refuse input port of the large truck.

The above is the main method of use.However, except for transferring the garbage to a large OB van, the garbage storage device is to be transferred to the final disposal site so that the garbage can be discharged directly to the disposal site. The garbage storage device is mounted on the traveling vehicle via the mounting portion. If the garbage storage device can be tilted from horizontal by raising or lowering one of the mounting portions on the traveling vehicle side, the garbage storage device is dumped. At the same time, by rotating the storage drum, dust can be efficiently discharged. In this case, the opening / closing door on the rear side is opened, the end of the drum on the charging port side is widely opened, and dust is discharged therefrom.
