Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a schematic plan view of a bottom-opening container according to the present invention, in which a side plate 1 and a bottom plate 2 surrounding four sides are provided.
The bottom plate 2 is formed by splitting the bottom plate pieces 2a and 2b into a central part by a universal joint 3 at the center.

[0006] The universal joint 3 has a support shaft 4 having both ends formed in a hook shape. Both ends of the support shaft 4 are formed through vertical slit holes 1a provided in the opposite side plate 1 of the container as shown in FIGS. The bottom plate 2 can be opened and closed by moving the protruding end 4a along the slit hole 1a.

In FIG. 4, the solid line indicates the closed state of the bottom plate 2 and the protruding end 4a of the support shaft 4 is stationary at the P position.
When the bottom plate pieces 2a and 2b are pivoted downward around the universal joint 3 and moved toward the center as shown by a two-dot chain line when the object is pulled up to the Q position along the line a, the space between the bottom plate pieces 2a and 2b is opened with the opposing side plate 1. Thus, openings S are formed at both ends.

When the protruding end 4a is further raised from this state to the R position (upper end of the slit hole 1a), the bottom plate pieces 2a and 2b move around the universal joint 3 at a maximum as indicated by the two-dot chain line. It moves to the center and the opening S between it and the opposing side plate 1 is maximized. That is, the protruding end 4a of the support shaft 4
The bottom plate 2 is pulled up along the slit hole 1a.
The two ends of the bottom plate pieces 2a, 2b are pivotally pulled toward the center while rotating, and the openings S are formed on both sides, and the opening ratio of the openings S can be freely changed depending on the degree of lifting of the protruding end 4a. You can do it.

Here, 5 is a roller mounted on both sides of the lower surfaces of the bottom plate pieces 2a, 2b near the ends, and a guide portion provided at the lower end of the opposing side plate perpendicular to the opposing side plate 1. 6 so as to be movable along the bottom plate 2
This is for keeping the movement of the bottom plate pieces 2a and 2b smoothly following the rotation of the bottom plates a and 3a.

In order to close the bottom plate 2, the protruding end 4a may be lowered from the R position to the P position. With this lowering, the bottom plate pieces 2a and 2b gradually rotate upward around the universal joint 3. While moving toward the end, and stops when the bottom plate 2 indicated by a solid line in FIG. 1 to 3, reference numeral 7 denotes a lifting ring, which is attached to the four corners of the upper frame 1b.

The bottom-open container 8 constructed as described above.
For example, as shown in FIGS. 5 and 6, the residue can be supplied to a hopper 9 of a vehicle-mounted crusher (not shown) of the residue carrier. That is, after the residue generated at the construction site or the like is stored in the bottom-opening container 8, the residue is lifted by a vehicle-mounted or truck crane using the lifting ring 7, moved to the upper part of the hopper 9, and then gradually lowered. At this time, the protruding end 4a of the support shaft 4 is connected to the rim 9a of the hopper 9.
And the bottom of the bottom-opening container 8 is hopper 9
The protruding end portion 4a is pulled up along the slit hole 1a as it is dropped inside. As a result, as described above, the bottom plate pieces 2a and 2b rotate downward around the universal joint 3 to form an opening S, and the residue falls from the opening S and is supplied into the hopper 9. Therefore, the opening operation of the bottom plate 2 can be automatically performed by a lowering operation of a vehicle-mounted type or a truck crane or the like, and a mechanism or a power source for lifting the protruding end 4a is unnecessary.

At the time of supplying the residue, the amount of the residue supplied into the hopper 9 can be adjusted by adjusting the opening ratio of the opening S. Therefore, the residue can be supplied in an appropriate amount according to the operation state of the crushing device, without applying an unreasonable load to the crushing device, the residue does not overflow from the hopper 9 and spill out, and the bottom-open container 8
Since the opening S is located in the hopper 9, it is possible to prevent dust and small pieces generated when the residue falls from scattering to the outside as much as possible. If the aperture ratio of the bottom plate 2 is maximized,
Of course, it is also possible to supply a large amount of residue at a time.

If the bottom-opening container 8 is lifted after the end of the supply of the residue, the projecting end 4 a is
a while gradually descending along the slit hole 1a while being received by the a, the bottom plate pieces 2a, 2b are moved in the end direction while rotating upward around the universal joint 3 as described above, The bottom plate 2 can be closed. That is, the closing operation of the bottom plate 2 can also be automatically performed by a hoisting operation such as a vehicle-mounted type or a truck crane, and a mechanism and a power source for pushing down the protruding end portion 4a are unnecessary.

The residue formed into chips by the crushing device is directly carried out from a construction site or the like by a residue carrier, but may be transferred to a dump truck and then carried out. In this case, the bottom-open container 8 removes the residue into the dump truck. Used to load. In this case, the operation is the same as that performed by an on-vehicle type or a truck crane, but there is no place where the protruding end 4a is hooked on the dump truck carrier. Will be needed. This operation means can be used as a vehicle-mounted type or a truck crane by hooking a hook on the protruding end.

When loading onto a dump truck, even if it is opened, the bottom plate 2 is drawn into the container in a folded state, so that the bottom plate 2 is placed near the upper surface of the loading platform or as close as possible to the residue surface loaded earlier. The dust can be supplied, thereby suppressing the scattering of dust and small pieces generated when the chipped residue falls.

FIG. 7 shows another embodiment of the bottom-opening container according to the present invention, in which the bottom plate 12 moves the ends of the divided bottom plate pieces 12a and 12b up and down along the opposite side plate 11 of the container. Each bottom plate piece 12a, 1
2b is rotated downward so that an opening S 'is formed between the central ends of the bottom plate pieces 12a and 12b. When the residue is discharged, the bottom plate piece 12 is removed.
The opening ratio of the opening S 'can be freely adjusted by changing the rotation angle by adjusting the lifting of a and 12b.

Also in this case, the opening and closing operation of the bottom plate 12 is performed by projecting a hooking end (not shown) to the outside through a slit hole provided in the opposing side plate, and through this protruding end, a vehicle type or a truck crane is used. A roller is attached to the center end of the bottom plate pieces 12a and 12b so that the bottom plate pieces 12a and 12b can be moved along a guide provided at the lower end of the opposite side plate. It is preferable to make the movement smooth and reliable.

[0018]

As described above, according to the present invention,
Since the opening ratio of the opening in the bottom-opening container can be adjusted, the amount of waste such as residue can be adjusted, and for example, it becomes possible to supply the residue to the hopper of the on-board crusher in an appropriate amount. In addition, the present invention provides excellent effects such as not applying an excessive load to the crushing device, preventing the residue from overflowing from the hopper and spilling out, and preventing the scattering of dust and small pieces generated when the residue falls. Furthermore,
Since the bottom plate can be opened and closed automatically by operating a vehicle-mounted or truck crane, there is no need for a separate opening / closing mechanism or power source, so labor and equipment costs can be reduced and safety is high. Also play.
