The disintegrator has blade shafts (3) separable between a middle piece (32) and an end piece (33) by a separation joint (34). The middle piece is equipped with a cam (31). The joint is aligned differing from a longitudinal axis of the shaft. A groove (35) or an indent is formed on a surface of the adjacent middle and end pieces. A spring (36) or a rib of a length is slidable in the grove or the indent, and provided as a part of another surface of the pieces. The middle piece is detached from a container (1) i.e. shovel, in a region of the end piece, which is mounted in the container. |
