Abstract
A bulk material conveyor belt scraper comprises a base portion having a C-channel. The belt scraper also comprises a polymeric portion that protrudes outwardly from a corner of the C-channel. The C-channel of the belt scraper is adapted to engage with and partially encircle a support member having a square portion in a manner such that the support member is able to bias the belt scraper against a conveyor belt.
Claims16
A bulk material conveyor belt scraper comprising a polymeric portion and a metal base portion, the belt scraper extending longitudinally along a longitudinal axis, the base portion comprising a C-channel portion and a protrusion that extends along the longitudinal axis, the C-channel portion having a corner, the protrusion extending outwardly from the corner of the C-channel portion and defining an opening that extends longitudinally through the base portion of the conveyor belt scraper, the polymeric portion being attached to at least the protrusion of the base portion.
A bulk material conveyor belt scraper comprising a polymeric portion and a metal base portion, the belt scraper extending longitudinally along a longitudinal axis, the base portion comprising two opposing engagement surfaces and an intermediate engagement surface perpendicular thereto, two opposing engagement surfaces and the intermediate surface being configured to engage against three sides of a square tube in a manner preventing the belt scraper from rotating relative to the square tube, the base portion also having a protruding portion that extends the length of the belt scraper and is configured to extend outwardly of a corner of a square tube when the belt scraper is attached to such a square tube, the protrusion forming an opening or channel that extends the length of the belt scraper, the polymeric portion being attached to at least the protrusion of the base portion.
A bulk material conveyor belt scraper assembly comprising a support member extending along a longitudinal axis and a belt scraper, the support member comprising a square opening extending longitudinally through the support member, the support member also comprising a longitudinally extending stiffening rib protruding from a corner of the support member, the belt scraper comprising a base portion having a C-channel, the belt scraper also comprising a polymeric portion that protrudes outwardly from a corner of the C-channel, the C-channel of the belt scraper being engaged with and partially encircling the support member in a manner such that the polymeric portion of the belt scraper extends opposite the stiffening rib.
A method of forming a bulk material conveyor belt scraper comprising:
- welding a first metal channel to a second metal channel, the first channel being a C-channel having an exterior corner, the first metal channel being welded to the second metal channel in a manner such that the second metal channel bridges over the exterior corner of the first metal channel and forms a channel passageway bound by the first and second metal channels;
- and
- bonding a polymeric material to the second channel after welding the first and second metal channels to each other.
