摘要 |
The invention relates to a device for affixing cutter drums on an apparatus designed to cut trenches in the ground. The driver includes a revolving plate 4 disposed perpendicular to its axis and to the end of the latter, the plate having on its periphery a convex polygonal shape 9. A cutter drum 8 is provided with a portion 8a including a central hollow of concave polygonal shape 10 corresponding to the convex polygonal shape 9 of the plate 4 and of slightly greater dimensions. Bolts 11 unite the cutter drum 8 to the said plate 4 such that the rotational driving of the cutter drum 8 by the plate is performed through the medium of the aforesaid polygonal surfaces 9, 10 which come into engagement with one another. |
