The segment body for a conveyor belt scraper includes a plate-shaped mounting element, which can be connected to a flat bearing profile of a segment carrier, a carrier section, wherein the carrier section is formed on a first end area of the mounting element by means of a supporting area and an underside of the carrier section forms a hollow body together with an opposite section of the mounting element so that the carrier section is resiliently supported on the mounting element by means of the supporting area in order to form a first damping mechanism; and wherein the carrier section has at least one insertion pocket on the underside of the carrier section, which insertion pocket is suitable for accommodating a spring element in order to form a second damping mechanism. | 08-15-2013 |
20130264173 | DUAL BELT CLEANER - A cleaning assembly for a conveyor belt includes a first blade assembly, a second blade assembly, and a coupling mechanism supporting the first and second blade assemblies. The first blade assembly includes a first blade positionable into contact against a conveyor belt adjacent a turn portion of the belt. The second blade assembly includes a second blade positionable into contact against the belt downstream from the first blade. | 10-10-2013 |
20130299311 | FLIP-ABLE V-PLOW BELT CLEANER - A V-plow belt cleaner has a cleaning element providing first and second opposing cleaning edges which can be flipped over so that the second cleaning edge is adjacent the conveyor belt; and reconnecting the V-plow belt cleaner to its mount. The flip-able V-plow belt cleaner may comprise: left and right arms defining an apex and providing a mounting interface for cleaning media; a front arm holder attached proximate the apex; a rear support bar attached proximate rearward ends of the arms for maintaining a spacing; one or more rear arm holders attached to the rear support bar; and two or more power arms for connecting to a V-plow mount, each power arm being pivotably connected to a front or rear arm holder and being mountable to positions both above and below the V-plow cleaner. | 11-14-2013 |
20140131171 | REMOVABLE CARTRIDGE CLEANER - A removable cartridge cleaner assembly is provided that allows for faster and easier removal of the belt cleaner blades out from under a conveyor belt. In one aspect the assembly includes a biasing surface of one of an elongate support assembly and a channel member configured to be engaged by a securing member and urge distal ends of legs of the channel member into tight engagement with the elongate support assembly and minimize debris accumulation therebetween. In another aspect, the elongate base member and rail member each include lateral portions configured to slidably engage corresponding wedge portions to urge the rail member toward the base member. A method of installing a belt cleaner assembly is also provided which includes camming a rail member downwardly toward the support member upper surface. | 05-15-2014 |
20140262688 | SCRAPING DEVICE FOR A TRANSPORTING BELT AND CORRESPONDING MANUFACTURING METHOD - A device including a supporting structure, at least one scraping member upwardly and downwardly delimited by upstream and downstream sides, and an elastic material that is overmolded on the scraping member and connecting the scraping member to the supporting structure, the upstream side of the scraping member being covered with the overmolded elastic material. | 09-18-2014 |
20140360842 | IMPROVED BELT SCRAPER MOUNTING - An improved bet scraper mounting for belt conveyors having conveyor frame/stringer, comprising: scraper blade module assembly ( | 12-11-2014 |
20150360880 | CONVEYOR BELT CLEANER WITH REMOVABLE CLEANER ASSEMBLY - A conveyor belt cleaner is provided having a removable cleaner assembly that may be easily connected and disconnected from an elongate support member. The cleaner assembly includes one or more scraper blades mounted to an angle bar, an interface between the blades and the angle bar, and an interface between the blades and the support member. The blades have bodies that cover or surround the interfaces and reduce the likelihood of debris entering the interfaces and binding the blades to the angle bar and/or the support member. The cleaner further includes a securing mechanism with a pair of clamps for clamping the angle bar against seats of the elongate support. The clamps cause the angle bar to hold a base portion of the blades against the support member which permits the blade base portions to transmit loading from the conveyor belt directly to the support member. | 12-17-2015 |
20160001982 | Conveyor Belt Cleaner - In accordance with one aspect, a cleaner for a conveyor belt is provided having a scraper blade for engaging a conveyor belt traveling in a downstream direction and a rigid fulcrum member extending laterally transverse to the downstream direction. The cleaner includes a blade mount member having an upper arm portion connected to the scraper blade, an intermediate portion spaced upstream from the rigid fulcrum member, and a lower arm portion extending from the intermediate portion, under the rigid fulcrum member, and downstream beyond the fulcrum member. The cleaner has a resilient support for the blade mount member configured to allow the blade mount member to resiliently rock about the rigid fulcrum member as the scraper blade is impacted during conveyor belt operations. | 01-07-2016 |
