A system for rapid and easy replacement of sacrificial machine parts, utilizing an adapter having a slot and a retainer pin fitted with at least one spring-loaded ball bearing suitable for engaging the slot when the retainer pin is inserted into the adapter.

대표청구항 ▼

1. A tooth assembly, comprising: an adapter having first and second tapered surfaces, and first and second sides, the first and second tapered surfaces converging toward a first end of the adapter; a tooth point coupled with the adapter at the first end, the tooth point having a contact edge opposite the first end of the adapter; a second end of the adapter adapted to be removably coupled with a tooth horn; the first side of the adapter including a portion which defines an internal bore extending at least partially therethrough, the portion adapted to receive a retainer pin; the portion further defining a first internal slot extending from the internal bore, the first internal slot configured to receive a detent member associated with the retainer pin; and wherein the portion of the first side of the adapter comprises a removable insert adapted to be received within a cavity defined by the first side, the cavity having a complementary shape to the insert, and wherein the insert defines the central bore. 2. The tooth assembly of claim 1, wherein a side of the tooth point defines at least one opening configured to receive the retainer pin, and wherein the side of the tooth point is configured to secure the insert within the cavity of the adapter. 3. The tooth assembly claim 2, further comprising: the retainer pin; and wherein the retainer pin extends through the opening and at least partially through the internal bore, the detent member engaging the internal slot and forming a removable coupling between the tooth point and the adapter. 4. A tooth assembly, comprising: an adapter having first and second tapered surfaces, and first and second sides, the first and second tapered surfaces converging toward a first end of the adapter; a tooth point coupled with the adapter at the first end, the tooth point having a contact edge opposite the first end of the adapter; a second end of the adapter adapted to be removably coupled with a tooth horn; the first side of the adapter including a portion which defines an internal bore extending at least partially therethrough, the portion adapted to receive a retainer pin; the portion further defining a first internal slot extending from the internal bore, the first internal slot configured to receive a detent member associated with the retainer pin; and comprising a non-rotation ridge extending at least partially into the internal bore, the ridge operable to engage a second slot defined by a base of the retainer pin, to prevent rotation of the retainer pin relative to the adapter.
