ABSTRACT:
The invention relates to a device for completely evacuating a silo containing finely divided material in bulk. A mobile box element passes over the floor of the silo, its face corresponding to the direction of advance being open and the horizontal base forming a shovel for collecting the material remaining on the floor of the silo. The bottom of the box element has a conveyor with transverse bars for pushing the pulverulent or granulous material located on the bottom of the box element towards an outlet trap located at one end of the box element and maintained level with a pit for evacuation by gravity; the box element is moved to sweep the surface of the silo. The invention is particularly applicable to the final evacuation of the silo containing granulous material such as cereals.
