A reversible belt scraper blade is supported on the support arms of a belt scraper by attachment fittings that permit the blade to be rotated, in place, while the weight of the blade is carried on the belt scraper arms.

Blade holder for conveyor belt reversible scraper blade

A reversible belt scraper is provided with opposite belt scraping surfaces and is adapted to be reversed by inverting. The belt scraper is formed with a pair of metal side frames, and a transversely elongated body is formed as a block of rubber defining the belt scraping surfaces on opposite sides. A pair of fiberboard backing plates are positioned to support the rubber block against forces tending to bend or deflect the rubber. The fiberboard backing plates wear at a rate faster than the wear rate of the rubber block and assure full contact between the belt and the rubber scraping body. In a further embodiment, ceramic bricks are embedded within the rubber block with wear surfaces at the rubber scraping surface. The rubber, brick and backing plates are formed in modular segments which are stacked end-to-end between the frames and retained by metal slugs which extend through the segments.

Reversible belt scraper blade for cleaning high speed conveyor belts

A modular skirt board clamp and saddle assembly for a bulk material conveyor includes a plurality of individual saddle frames which extend transversely of the direction of belt movement, arranged in longitudinal side-by-side relation, and each frame supporting a plurality of polymeric low friction blocks or segments, defining a belt supporting surface. Skirt board support arms are positioned at each lateral side of the assembly with lower ends joined to one of the lateral ends of the saddle frames, and extending vertically above the segments and transversely toward the opposite side. A pair of skirt boards are supported in clamping segments or plates, mounted on the arms, in which one of the clamping plates is fixed to the inner end of the arm, and the other is movable by a hand-operated, toggle mechanism. The belt is supported in immediate underlying relation to the skirt boards by elongated polymeric support segments which extend in common to each of the saddle frames.
