Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention allows an empty container to be placed in a predetermined position, and when the container becomes full with waste etc., a vehicle equipped with a cargo handling device This container is used in the field of collecting waste by loading the container onto the vehicle from the rear, transporting it to a predetermined location, discharging the waste, and then returning it to the predetermined location.

(b) Prior Art Generally, when loading a shipping container onto a vehicle from the rear using a cargo handling device with a rotatable arm, the front of the container placed on the ground is gradually lifted up and the container is It is designed to be loaded onto the vehicle body while tilting it backwards.

However, because conventional containers have horizontal floors, the maximum angle of inclination (approximately 30
degree) becomes larger than the angle at which the stored items start sliding (approximately 26 degrees), and there is a risk that the stored items will slide backwards and collide with the rear sliding door, damaging the sliding door or causing the container to swing. It was hot.

Further, when the rear door is opened downward, the opening/closing device for the rear door cannot be accommodated below the floor surface of the container because the floor surface of the container is horizontal, but is attached to the left and right sides of the container. As a result, the opening/closing device was a protruding object, which was extremely dangerous.

(c) Problems to be solved by the invention The present invention solves the above-mentioned problems.
The floor surface of the shipping container is sloped forward and downward, reducing the angle of inclination of the floor surface when loading into the vehicle body to prevent contents from slipping, and the rear door opening/closing device is installed on the floor surface at the rear of the container. It is housed in the lower part to prevent the opening/closing device from becoming a protrusion.

(d) Means for Solving the Problems The present invention provides a transportation container that is loaded onto a vehicle body from the rear of the vehicle body using a cargo handling device having a rotatable arm provided on the vehicle body. The front wall is provided with an engaging member that can engage with the hook at the tip of the cargo handling device, the rear wall is provided so that it can be opened and closed, the floor surface is sloped downward in the front, and support means for when placed on the ground is provided below. This relates to a shipping container.

(e) Embodiment An embodiment will be described below with reference to the drawings. Reference numeral 1 indicates a transport vehicle for transporting a transport container 2 of the present invention. The transport vehicle 1 has a cargo handling device 6 on the vehicle body 3, which includes a rotating arm 4 and a dump frame 5, and the rotating arm 4 loads and loads containers 2 from the rear of the vehicle body 3.
After loading and unloading, container 2 is loaded onto dump frame 5.
is dumped, and the waste in the container 2 is discharged.

To explain the container 2 in detail with reference to FIG. 2, an engaging member 9 that can be engaged with a hook 8 at the tip of the rotating arm 4 is provided at the upper center of the front wall 7.

The lower end of the rear wall 10 of the container 2 is pivotally supported,
It is designed to be opened upward from an opening/closing device 11 which will be described later.

The floor surface 12 of the container 2 is tilted downward at an angle of about 5 degrees (θ).

As a result, even if the container 2 is tilted to the maximum (approximately 30 degrees) when loading the container 2, the inclination angle of the floor surface 12 itself (approximately 25 degrees) is reduced to the angle at which the waste slides out (approximately 26 degrees).
The container 2 can be loaded while the waste remains stationary.

At the front and rear positions of the main girder 13 of the container 2, rollers 14, 14, which are supporting means for installing the container 2 on the ground, are provided.

The opening/closing device 11 is connected to a floor surface 1 at the rear of the container 2.
2, and is comprised of a link device 17 consisting of a bell crank 15 and a rod 16, and a hook device 18 that holds the link device 17 in a closed state with respect to the rear wall 10.

When the container 2 is loaded onto the vehicle body 3, the hook device 18 is forcibly rotated by a first cam 19 that is integral with the vehicle body 3, thereby preventing the hook device 18 from engaging with the link device 17. comes off (Figure 4b),
When the container 2 is dumped in this state, since the hook device 18 is held by the first cam 19, the rear wall 10 rotates under its own weight until it becomes flush with the floor 12. (Figure 4c).

Also, when the container 2 is lowered, the link device 1
A portion of the rear wall 10 is guided by a second cam 20 fixed to the vehicle body 3 to close the rear wall 10.

21 is a tilting device for dumping the dump frame 5.

Although rollers are used as the support means in the embodiment, the support means is not necessarily limited to rollers, and any support means that can stably install the container will have similar effects.

The present invention has the above-mentioned configuration. Next, the operation will be explained. First, when the container 2 is installed,
Since the link device 17 is engaged with the hook device 18 and the rear wall 10 is held in a closed state, waste materials etc. are loaded in this state.

When the waste is full, the transport vehicle 1 comes and attaches the hook 8 of the rotating arm 4 to the container 2 as shown in Figure 1.
The container 2 is loaded from the rear by engaging with the engaging member 9 of the container 2 and rotating the rotating arm 4 accordingly by a driving means.

At this time, since the inclination angle of the floor surface 12 is always smaller than the angle at which the waste etc. slide out, the waste etc. do not collide with the rear wall 10.

Further, when container loading is completed, the hook device 18 is disengaged by the first cam 19 as shown in FIG. 4b.

Next, when discharging waste etc., when the dump frame 5 is dumped by the tilting device 21, the rear wall 10 rotates under its own weight until it is flush with the floor 12.
Waste materials are discharged to the rear.

(f) Effects of the invention As described above, the present invention has a rear wall that can be opened and closed, and the floor surface is sloped forward and downward, so that it is possible to prevent the contents from sliding when loading a container, which is different from the conventional method. This eliminates the possibility of damaging the rear wall or shaking the container, allowing work to be carried out safely.

Furthermore, since the rear door is provided to be able to open upward and the opening/closing device for the rear door is housed in the lower part of the floor at the rear of the container, the opening/closing device does not become a protruding object and is very safe.
