Furthermore, although the mechanism for transmitting power from the power source to the impeller 33 was a gear mechanism, it may also be a belt mechanism. The rails 8 do not need to be straight, as they are laid in accordance with the size and shape of the storage 1 and the position and arrangement shape of the extraction ports 4, and may be plural for use with multiple reclaimers. Good too. In the drawing, the upper surface of the rail 8 is located above the floor level of the refrigerator, but in order to minimize the amount of loose material remaining on the floor of the refrigerator after the reclaimer 6 of the present invention performs the cleaning work, the rail 8 is placed above the floor level of the refrigerator. It is preferable that the upper surface of the curved blade 24 be provided at the same level as or near the floor level of the refrigerator interior so that the curved blade 24 comes into sliding contact with the floor surface of the refrigerator interior.

Effects of the invention As described above, the present invention rotates the impeller while moving the traveling trolley surrounded by the protector and the impeller toward the loose object, and at the same time swings the harrow to move the traveling trolley forward. The claws of the harrow can break down the remaining loose material in the warehouse in front of the cart, and the broken loose material can be scraped off by the blades of the rotating impeller and fall into the extraction port. By means of the protector surrounding the traveling carriage and the rotating impeller, it is possible to eliminate loose objects that impede the forward movement of the traveling carriage. In addition, by changing the rocking speed of the harrow rocking drive device depending on the nature of the bulk material, such as whether it is easy to crumble or hard to crumble, the amount of bulk material to be cut is adjusted, and the appropriate amount is set for the blades of the impeller. You can cut loose items into pieces. Furthermore, the impeller has an outer diameter that is slightly smaller than the inside width of the storage, and in order to rotate it in a horizontal plane along the protector and the running surface of the trolley, the blades of this impeller are used to loosen the remaining inside of the storage on the side of the trolley. Objects can be scraped off and dropped into the outlet. Therefore, for bulk materials of any nature, cleaning work can be carried out using just a reclaimer, eliminating the need for cleaning work using bulldozers, etc., and reducing equipment and labor costs. Since the driving operation is easy, remote automatic driving is also possible.
