That is, the crawler device 4 is driven to move the conveyor device 1 to the quay 67. After that, the dump truck 65 is moved to the inclined table 17.
Then, the soil 21 is thrown into the throwing hopper 16. Thus, the earth and sand 21 is supported on the belt 9 of the belt conveyor body 3 and is transported along the transport path 68.

The earth and sand 21 conveyed to the discharge portion 19 of the belt conveyor body 3 is discharged from the belt 9 to the discharge hopper 69, and the inner cylindrical portion 27 of the upper cylindrical member 23 and the lower cylindrical member are discharged from the discharge hopper 69. After passing through the inner cylindrical portion 38 of the slide 24 and sliding down the inside of the chute main body 25, the chute 25 is discharged downward from the discharge port 57 and loaded on the earth and sand transport ship 66.

At this time, when the electric motor 49 is operated, the drive gear 50 rotates and the ring gear 51 is driven to rotate, so that the lower cylindrical body 24 rotates about the vertical axis 46.

As shown in FIG. 1, when the rear cylinder device 15 is operated, the rear main body 3b of the belt conveyor main body 3 swings up and down around the intermediate shaft 13, so that the conveyor main body 3 The inclination angle of the rear body 3b is increased or decreased.

As shown in FIGS. 2 and 3, when the inclination angle α of the rear body 3b of the belt conveyor body 3 is increased or decreased (the inclination angle α in FIG. 2> the inclination angle α in FIG. 3),
By operating the swing cylinder device 34, the upper cylindrical body 23 swings in the front-rear direction (the direction of the transport path 68) around the horizontal axis 33. Thereby, the direction of the chute device 20 with respect to the belt conveyor main body 3 can be always kept constant (for example, downward as shown in FIGS. 2 and 3).

When the lower tubular body 24 is rotated with respect to the upper tubular body 23 as described above, as shown in FIG.
The supported frame 44 rotates integrally with the lower tubular body 24 while being supported by the support frame 43 via the bearing device 45. At this time, since each roller 47 presses the supported frame 44 downward while rolling on the rail 48, it is possible to prevent the lower cylindrical body 24 from floating with respect to the upper cylindrical body 23.

In the above embodiment, as shown in FIG.
The winch 60 for winding the wire 61 is used as an example of the vertical swinging means 62.
May be provided between the outer cylindrical portion 37 and the chute main body 25.

In the above embodiment, as shown in FIG.
The self-propelled conveyor device 1 which can be self-propelled by the crawler device 4 has been described. However, the present invention is not limited to the self-propelled conveyor device, and may be a hand-held moving conveyor device or a conveyor device fixed at one place. Good.

In the above embodiment, the chute device 20 is provided on the belt conveyor main body 3, but is not limited to the belt conveyor, but may be provided on another type of conveyor.

In the above embodiment, the earth and sand 21 is conveyed by the belt conveyor body 3 as an object to be conveyed.
Other than 1 may be transported. In the above embodiment,
The rotating means 52 comprises an electric motor 49, a driving gear 50, and a ring gear 51, but instead of the ring gear 51, a chain is provided on the outer peripheral surface of the outer cylindrical portion 37 of the lower cylindrical body 24, and the driving gear Instead of 50, a sprocket meshing with the chain may be used.

[0035]

As described above, according to the present invention, the conveyed object conveyed to the discharge section by the conveyor body is discharged downward from the chute device. At this time, by rotating the chute device or swinging up and down,
The direction of the conveyed object discharged from the chute device can be changed in the front-rear, left-right, and up-and-down directions. Therefore, the drop point of the discharged conveyed object can be easily changed. This makes it possible to adjust the shape and size of the peaks of the conveyed object that is discharged and deposited.
