When the lower end of the bucket elevator section 14 reaches near the floor of the storage area, the elevator truck 13 is made to traverse from the rear wall 2 side to the front wall 1 side to remove the lowermost bulk material. Pay out. When the front end on the lower end side of the bucket elevator 14 reaches the front wall 1 side, the girder 6 is run, and the work similar to the second step work is repeated to perform payout.

As a fourth step work, the dead pile having a triangular cross section remaining at the corners of the floor of the storage and the rear wall 2 is discharged.

Therefore, according to this embodiment, it is possible to scrape without leaving dead piles, and furthermore, since the loose material on the floor is slack in the lower part of the L-shaped chain 19, it can be scraped well. Can be taken.

Next, in order to move the bucket elevator type reclaimer 10 of this embodiment over the bulkhead 3 to the adjacent storage area, the hydraulic cylinder 24 is contracted as shown in FIG. The parallel links 21 and 22 are lifted upward and the girder 6 is run in the vertical direction a. Therefore, the L-shaped chain
The lower part of the window 19 does not hit the partition wall 3.

Next, the operation of stacking the bulk materials is performed as follows. When the lower end of the dustproof telescopic shoe 38 is moved upward and the girder 6 is run, the girder 6
At the same time, the tripper frame 49 on the ground side accompanies and stops the girder 6 when it comes to the desired storage location. Therefore, the ground side loading / unloading belt conveyor 9 and the girder side loading / unloading belt conveyor 43 are driven in a direction opposite to the direction of the payout operation. Therefore, the ground side loading / unloading belt conveyor 9
The loose goods sent by the ship are on the ground side tripper frame 49.
Is transferred from the upper shoe 47 to the girder-side loading / unloading belt conveyor 43, and the loose material on the girder-side loading / unloading belt conveyor 43 is transferred to the head pulley 3 of the tripper carriage 36.
