A scraper blade for a conveyor belt system, the blade having a pair of parallel tubes in a core region of the blade, integrally molded into elastomeric material. A plurality of spacers are provided to maintain the tubes in parallel arrangement during the molding process. End mounts are secured to the ends of the tubes to facilitate mounting on holders of the conveyor belt system.

In many fields, such as manufacturing and mining, compressed air is used as a power source for industrial equipment, hand power tools, etc. Extensive compressed air systems are installed in these environments to supply compressed air where it is needed. In mining, extensive belts are frequently used to move mined material. Idler rollers are located intermittently along these belts. Embodiments of the present invention include compressors located within these idler rollers. As the belt moves and causes the roller to turn, a compressor within the roller generates compressed air. Because the belt moves nearly continuously, but the compressed air may not be consumed continuously, the air will be vented periodically. Embodiments of the present invention use these vents to clean the filters for the system. Also, some embodiments of the compressor may be produced using a laminated, or stacked, method.

A concave conveyor belt idler system for use on the return run of a conveyor belt system, the idler being configured to maintain alignment of the belt and inherently adjust any misalignment thereof occurring during operation of the system. The concave conveyor belt idler system includes an elongated support member extending transversely of a conveyor belt return run and supporting a plurality of idler roller modules positioned such that the roller modules along the anterior side of the support member define a cave shape for supporting the conveyor belt, with the outer lateral edges at a lower elevation than the central portion of the conveyor belt. In a conveyor belt system the concave conveyor belt idler of the disclosed technology is positioned between two planate idler systems, on the return run, so that the center roller of the concave idler is in or near the plane of the belt as it traverses the planate idler systems, with the remaining rollers of the concave idler positioned below this plane.

A reversible belt scraper has two opposed replaceable scraper blades and a central shaft. Each replaceable scraper blade has a scraping surface and a base opposite to the scraping surface. The body of the scraper blades from the scraping surface to the base is comprised of elastomeric material. The scraper blades have at least one bracket in their bases. In at least one embodiment, the scraper blades have a plurality of brackets in their bases. The brackets in the bases of the scraper blades attach to the central shaft. End mounts at the end of the central shaft provide a means to mount the reversible belt scraper. In at least one embodiment, the brackets in the replaceable scraper blades are formed in a manner to accommodate the other scraper blade and allow both scraper blades to be mounted in a single row of apertures in the central shaft.

A wear and shock resistant multi-strata panel for lining a conveyor chute bearing aggregate, coal, and other bulk materials. The panel comprises a plurality of generally planar layers, and a plurality of panels may be used to line a chute. The layers are comprised of and sequentially arranged in a topmost ceramic layer, a corrosion-resistant first metallic layer, an elastomeric cushioning layer, and a bottom-most corrosion-resistant second metallic layer proximal to and in intimate contact with the chute support structure, or chute surface. The layers are consecutively bonded together to form a panel attached integrally to the chute structure.

A reversible belt scraper blade provides two opposed scraping surfaces on an integrally constructed body. Each scraping surface has an elastomeric wear region transitioning to an elastomeric central region. Two integral frame members are integrally joined into the central region. Each integral frame member runs the length of the belt scraper blade and is at least partially exposed at their ends. End mounts attach to the exposed integral frame members and the reversible belt scraper blade is reversible about the end mounts. The wear regions may have sub-regions of different hardness to provide good scraping qualities combined with improved structural rigidity. The central region may also have sub-regions of different hardness to improve structural rigidity.

Scalper blade for a conveyor belt cleaner

A scalper blade assembly for cleaning a conveyor belt. The assembly includes an adjustment structure for adjusting a force applied against the blades for biasing the blades into engagement with the conveyor belt. The adjustment structure includes a ratchet mechanism for incrementally adjusting the biasing force and a clamping structure for maintaining the position of blades and resisting forces applied against the blades from the conveyor. In addition, a blade support assembly is provided for facilitating mounting and replacement of scalper blades. The support assembly includes a support member and a locking member located within the support member, where movement of the locking member relative to the support member is operable to engage and disengage engagement members associated with the blades in locking engagement with the support member.
