ABSTRACT:
A splitting blade changing device for a block splitter, comprising a revolving mechanism in which an upper rotary member is suspended by a supporting plate which is moved up and down by a cylinder installed in an upper part of a gate-like frame, a plurality of upper blades are held on a circumferential face of the upper rotary member, a slit is provided in a table which is supported in a lower portion of the gate-like frame via buffer members, an lower rotary member fixed detachably on a bottom plate of the gate-like frame is installed in a lower part of the table, a plurality of lower blades facing the upper blades are held on a circumferential surface of the lower rotary member such that one of the lower blades protrudes from the table surface via the slit of the table, and the upper and lower rotary members sequentially select and install the upper blades and lower blades. The device enables the attainment of split blocks having a desired surface shape without requiring a cumbersome process of replacing splitting blades.
