Guided cartridge belt cleaner

A belt cleaner assembly comprising:

• an elongate support member for extending longitudinally across a conveyor belt;
• a cartridge for supporting at least one scraper blade thereon, the cartridge slidable over the support member;
• and
• slide blocks between the support member and the cartridge to space facing surfaces of the cartridge and the support member from each other,
• wherein the support member comprises a support shaft having a generally square cross-sectional configuration with upper and lower surfaces extending between lateral side surfaces having the slide blocks disposed thereon, and wherein the cartridge includes downwardly-extending legs having retention rails secured thereto so that with the cartridge slid over the support shaft the retention rails protrude laterally inward below the slide blocks and above the lower surface of the support shaft to inhibit tipping of the cartridge by engagement of at least one of the retention rails with at least one of the slide blocks.

A belt cleaner assembly comprising:

• an elongate support member for extending longitudinally across a conveyor belt;
• a cartridge for supporting at least one scraper blade thereon, the cartridge slidable over the support member;
• and
• slide blocks between the support member and the cartridge to space facing surfaces of the cartridge and the support member from each other,
• wherein the support member comprises a support shaft having a generally square cross-sectional configuration with upper and lower surfaces extending between lateral side surfaces, and wherein the slide blocks include upper slide blocks secured to and spaced apart along the upper surface of the support member and side slide blocks secured to and spaced apart along the lateral side surfaces of the support member.

A belt cleaner assembly comprising:

• an elongate support member for extending longitudinally across a conveyor belt;
• a cartridge for supporting at least one scraper blade thereon, the cartridge slidable over the support member;
• and
• slide blocks between the support member and the cartridge to space facing surfaces of the cartridge and the support member from each other,
• wherein the slide blocks include first generally rectangular slide blocks having long axes orthogonal to a central axis of the support member, and second generally rectangular slide blocks having long axes parallel to the central axis of the support member.

A belt cleaner assembly comprising:

• an elongate support member for extending longitudinally across a conveyor belt;
• a cartridge for supporting at least one scraper blade thereon, the cartridge slidable over the support member;
• and
• slide blocks between the support member and the cartridge to space facing surfaces of the cartridge and the support member from each other,
• wherein the slide blocks are longitudinally spaced apart to define a longitudinal gap between adjacent slide blocks.

A belt cleaner assembly comprising:

• an elongate support member for extending longitudinally across a conveyor belt;
• a cartridge for supporting at least one scraper blade thereon, the cartridge slidable over the support member;
• and
• slide blocks between the support member and the cartridge to space facing surfaces of the cartridge and the support member from each other,
• wherein the support member includes a lateral side surface, and the slide blocks are secured to the lateral side surface of the support member to guide the cartridge during sliding of the cartridge relative to the support member.

A resilient mounting assembly for a belt cleaner for a conveyor belt, the resilient mounting assembly comprising:

• a mounting plate for being fixed to a conveyor structure and having an opening to allow a support member to extend therethrough, the support member configured to allow belt cleaner blades of the belt cleaner to be mounted thereto;
• a plurality of circumferentially spaced guide blocks having arcuate guide surfaces each having the same radius of curvature, the plurality of guide blocks secured to the mounting plate such that the arcuate guide surfaces have the same radial distance to a central axis of rotation;
• and
• a rotatable cradle plate mounted to extend between the guide blocks and having the support member and belt cleaner blades operatively secured thereto for rotation therewith, the cradle plate having an outer arcuate periphery with a radius of curvature corresponding to the radius of curvature of the arcuate guide surfaces such that rotation of the cradle plate about the central axis relative to the mounting plate is guided by the arcuate guide surfaces.

A belt cleaner assembly comprising:

• an elongate support member having longitudinally-extending side walls;
• a cartridge for supporting at least one scraper blade thereon and being slidable along the support member;
• a pair of depending legs of the cartridge that are spaced to receive the support member therebetween with each leg extending along a corresponding adjacent one of the side walls;
• and
• retention members fixed relative to the side walls of the support member so that each retention member is spaced from a corresponding adjacent one of the side walls to form a gap therebetween, wherein the gaps are sized to receive the legs of the cartridge between the support member and the retention members when the cartridge is slid to an operative position along the support member.
