Selected.

  When the worker scrapes off the mud accumulated in the mud pool 5 of the storage tank A, first, the hose 7 lifted up during the work is laid and the water stretched in the storage tank A is discharged. Then, the operator rotates the rotating inclined plate 16, lifts the lifting tool 19 and the like by hooking 18 on the hook, and lifts the conveyance start end side of the conveyor B with the rotation fulcrum 21 as a fulcrum. Then, for example, a square bar or the like is held between the lifted transport conveyor B and the storage tank A, and the transport conveyor B is fixed in a lifted state. Then, the opening / closing plate 9 is opened, and the mud accumulated in the mud pool 5 is scraped out from the mud removal passage 8.

  At this time, by using the guide chute 14 as an elastic member, the crop is hardly damaged when the crop passes. Further, when the transport conveyor B is rotated, the guide chute 14 hits the cleaning device C and obstructs the rotation of the transport conveyor B, or the guide chute 14 itself is hardly damaged.
