The invention is a new design for dipper teeth for bulldozer buckets, comprising a pair of teeth joined by a plate, each tooth having a flat, pointed front edge, longitudinal U-shaped slot at its rear end, and bolt means disposed through an opening in the top surface to hold the teeth in position on the bucket.
Seaweed is picked up from the surface of a beach with general purpose earth moving machinery by installing a series of fingers extending forwardly and downwardly from the blade or bucket of the machine. By driving the machine forwardly along the beach, the fingers pass through the sand and seaweed on the beach travels up the incline of the fingers. The fingers accordingly act as a separator to separate most of the seaweed from most of the sand. Several embodiments of each moving machines are adapted for seaweed handling or removal.
The invention relates to a lip for an excavation bucket. The lip includes a lower plate defining a plurality of integral projections along a front edge thereof, an upper plate and a central plate sandwiched between the lower plate and the upper plate so as to form a laminated structure. The upper plate also defines a plurality of integral projections which together with the projections on the lower plate form tool attachment formations in a serrated front edge of the laminated structure for supporting ground-engaging tools on the lip.
