Abstract
A drive assembly for conveyor belt comprises a pair of opposing end plates for mounting a conveyor drive and mounting assemblies for mounting at least one of a position limiter assembly, a scraper assembly, a combined limiter-scraper assembly and side guards. The scraper assembly and combined limiter-scraper assembly include a leaf spring that is selectively tensioned by a tensioning element on an end plate to bias the scraper blade of the scraper assembly into an operational position.
Claims15
A drive assembly for a conveyor belt, comprising:
- a first end plate;
- a second end plate opposing the first end plate;
- a drive mounted to and extending laterally between the first and second end plates;
- a first saddle connected to the first end plate;
- a second saddle connected to the second end plate;
- a scraper assembly mounted to and extending between the first saddle and the second saddle;
- and
- a tensioning device including a first leaf spring that engages the first end plate and a second leaf spring that engages the second end plate for selectively moving the scraper assembly between an operational position and a cleaning position.
A scraper assembly for a conveyor belt, comprising:
- a pair of opposing scraper mounting plates;
- a substantially cylindrical base extending laterally between the pair of opposing scraper mounting plates for mounting a scraper blade, wherein the substantially cylindrical base includes a reduced-diameter neck portion configured to be received in a scraper assembly seat for mounting the scraper assembly between two end plates of a conveyor;
- and
- a leaf spring mounted to a mounting portion connected with each scraper mounting plate and extending in a first direction from the mounting plates for selectively biasing the scraper blade into a scraping position relative to the conveyor belt.
A scraper assembly for a conveyor belt, comprising:
- a pair of opposing scraper mounting plates, each scraper mounting plate including a channel forming an upper leg and a lower leg and a shaped protrusion extending up from the lower leg;
- a substantially cylindrical base extending laterally between the pair of opposing scraper mounting plates for mounting a scraper blade;
- a first leaf spring mounted to a first shaped protrusion and extending in a first direction from a first scraper mounting plate for selectively biasing the scraper blade into a scraping position relative to the conveyor belt.
A scraper assembly for a conveyor belt, comprising:
- a pair of opposing scraper mounting plates;
- a substantially cylindrical base extending laterally between the pair of opposing scraper mounting plates for mounting a scraper blade;
- a first mounting portion on a first scraper mounting plate;
- a leaf spring mounted to the first mounting portion for selectively biasing the scraper blade into a scraping position relative to the conveyor belt;
- and
- a shaped fulcrum point on the first scraper mounting plate spaced from the first mounting portion to form a pivot point for the leaf spring.
