Abstract: An adaptor for attaching a tooth to the arm of a cutter head. The adaptor having a rear coupling end and a front coupling end with a main cavity. The main cavity has a first upper surface, a first lower surface and two joining side surfaces. Each side surface has a side groove with a second upper surface parallel to a second lower surface. The second upper surface is approximately parallel to a lower segment adjacent to the bottom end on the first lower surface and the second lower surface of the side grooves is approximately parallel to an upper segment adjacent to the bottom end on the first upper surface. A distance between the second upper surface and the second lower surface of each groove is smaller than a distance between the upper segment and the lower segment of the main cavity.

Abstract: The tooth and adaptor for dredging machines. The tooth, attached to an adaptor, creates an assembly to deepen and clean the beds of ports, rivers, channels, etc., removing therefrom sludge, stones, sand, etc. The adaptor when attached to the blades forms the cutter head of the dredging machine. The constructive features of the coupling between the tooth and the adaptor allow improved stability between both elements, among other advantages.

Abstract: A tooth for attachment to a cutter head arm. The tooth has a front wear part and a rear coupling part, the rear coupling part having a main body with a rear free end and a forward end. The main body has a first upper surface, a first lower surface and two side surfaces joining both upper and lower surfaces, with the distance between the first upper surface and first lower surface decreasing towards the rear free end, side projections, and upper and lower segments. Each side surface has a side projection with a second upper surface parallel to a second lower surface, the second upper surface approximately parallel to a lower segment, and the second lower surface approximately parallel to an upper segment. The distance between the second upper surface and the second lower surfaces is smaller than the distance between the upper segment and the lower segment.

Abstract: The tooth and adaptor for dredging machines object of the present invention relates to a tooth which, attached to an adaptor, creates an assembly the purpose of which is to deepen and clean the beds of ports, rivers, channels, etc., removing therefrom sludge, stones, sand, etc., the adaptors being attached to the blades thus forming the cutter head of the dredging machine. The constructive features of the coupling between the tooth and the adaptor allow a great stability between both elements, among other advantages.

Abstract: Wearing element with enhanced wear resistance related to wearing elements, such as cast steel teeth to be specially used in machinery for earth-moving, ground-engaging and/or rock-cutting applications, as well as to inserts to be included within the wearing elements, to enhance their wear resistance thus prolonging their service life.
