Abstract
A digging wheel assembly includes a supporting wheel having a peripheral zone and a plurality of receiving elements affixed to the supporting wheel in the peripheral zone in a spaced, circumferential distribution. Each receiving element has a receiving pocket and a receiving slot. Digging tool components are disposed along the peripheral zone of the supporting wheel in a circumferential distribution. Each digging tool component is disposed between two circumferentially adjoining receiving elements; one being a leading receiving element and one being a trailing receiving element as viewed in the rotary working direction of the assembly. Each digging tool component has a leading part extending from a front end of the digging tool component in the rotary working direction and being accommodated in the receiving pocket of the leading receiving element. Each digging tool component also has a trailing part extending from a rear end of the digging tool component against the rotary working direction and being accommodated in the receiving slot of the trailing receiving element. The receiving elements form a securing arrangement for removably affixing the digging tool components to the supporting wheel.
