The conveyed object a conveyed upward is inherited by the upper conveyor device B disposed at a predetermined height from the installation floor surface G. Reference numeral 6 denotes an upper frame on which the upper conveyor device B is provided.

The casing 1 includes a long casing main body 10, an upper casing 11 connected to the upper end of the casing main body 10, and a lower casing 12 connected to the lower end.

[0005] The lower casing 12 comprises a lower casing body.
A sliding plate 12b is vertically slidably mounted on the outer surface of 12a, and a supporting shaft 3a of the lower sprocket 3 is supported on the sliding plate 12b. 12c is a screw rod for moving the sliding plate 12b up and down.

That is, since the conveyor chain 4 of the bucket conveyor apparatus X expands and contracts due to heat and the like, in order to cope with such expansion and contraction, the sliding plate 12b is moved up and down to move the support shaft 3a of the lower sprocket 3 up and down. By moving the conveyor chain up and down, the tension of the conveyor chain 4 can be adjusted. The lower casing body 12a has the support shaft 3a
Is provided with a long hole (not shown) so that it can slide up and down.

At the lower end of the lower casing body 12a, a bottom wall 8 having a structure described in detail later is provided to form a cargo storage space C having a substantially ship bottom shape in cross section. The transferred object a input from the hopper 14 communicating with one side wall can be stored in the transferred object storage space C. Reference numeral 15 denotes a feeder disposed so as to face the input port 14a of the hopper 14.

On the other hand, the upper casing 11
Is connected to the upper end of the casing 1 via a mount 7 supporting the upper end of the upper frame 6. The mount 7 stands on the upper frame 6.

Reference numeral 13 denotes an article taking-out duct connected to the upper casing 11, and the end of the duct 13 faces the upper conveyor apparatus B.

A drive motor (not shown) for driving the upper sprocket 2 is mounted on the pedestal 7, and the motor and the upper sprocket 2 are connected to each other via a drive chain. .

According to the above configuration, when the drive motor is driven to rotate the conveyor chain 4, the plurality of buckets 5 connected to the chain 4 turn around the lower sprocket 3 and pass through the conveyed object storage space C. At this time, the transferred object a
And transport them sequentially upward.

Then, when turning around the upper sprocket 2, the conveyed object a is discharged to the conveyed object take-out duct 13, and the conveyed object a is passed on to the upper conveyor device B.

Here, the lower casing body 12a described above is used.
The bottom wall 8 will be described with reference to FIG.

As shown in FIG. 8, the bottom wall 8 has a fixed bottom wall 81 provided at the center of the lower casing body 12a below the lower end of the side wall of the casing body 12a, Left and right movable bottom walls 82 and 83 having a base end pivotally attached to both end edges of 81 so as to be freely swingable, and a distal end extending obliquely upward and detachably connected to a lower end of the side wall. 84,85 are axes.

[0016]

However, the following problems still remain in the bucket conveyor apparatus X having the above configuration.

That is, as shown in FIG. 8, since the storage space C has a substantially ship bottom shape in cross section, the fixed bottom wall 81 is formed.
The distance between the tip and the tip of the bucket 5 located at the lowermost end becomes large, the amount of residue increases, and the transport efficiency is reduced.

Further, for example, if the transferred object a is easily rotted, the residue must be removed immediately.

Therefore, it is necessary to open the movable bottom walls 82 and 83 and scrape out the residue from the opening to remove it.
Cleaning was difficult because the central portion with the largest amount of residue was not open, and eventually the residue could not be completely removed.

However, if the transported objects a are of various types and have a problem when mixed, there is a risk that they will be mixed if there is any residue.

[0021] Therefore, it is necessary to remove the residue even if it takes time and effort, so that such a cleaning operation takes time, resulting in a decrease in the efficiency of the transport operation.

Further, in the conventional bucket conveyor apparatus X, when the conveyor chain 4 expands and expands, the bucket 5 may come into contact with the bottom wall 8.

In order to adjust the tension of the conveyor chain 4 by adjusting the support shaft 3a of the lower sprocket 3 vertically, it has been considered that the bottom wall 8 is linked to the movement of the support shaft 3a. However, there is a problem that the cost is high and the whole apparatus becomes extremely expensive.

It is an object of the present invention to provide a bucket conveyor device that can solve the above-mentioned problems.
