Abstract
A tensioning arrangement for a scraper for a conveyor belt, the tensioning arrangement comprising a hydraulic assembly that acts on the scraper to maintain a portion of the scraper in operative contact with the conveyor belt, the hydraulic assembly configured such that weight applied to a portion of the hydraulic assembly effects application of pressure on fluid contained within the hydraulic assembly.
Claims12
A tensioning arrangement for a scraper for a conveyor belt, the tensioning arrangement comprising:
- a hydraulic assembly that acts on the scraper to maintain a portion of the scraper in operative contact with the conveyor belt, the hydraulic assembly configured such that weight applied to a portion of the hydraulic assembly effects application of pressure on fluid contained within the hydraulic assembly, the hydraulic assembly including a holding piston and cylinder assembly, the holding piston and cylinder assembly being single-acting, wherein weight applied to one of the piston or cylinder applies pressure on fluid contained within the hydraulic assembly.
A conveyor belt scraper assembly comprising:
- a scraper blade to contact a conveyor belt to remove materials from a conveyor belt while the conveyor belt is in use;
- a hydraulic tensioning assembly which biases the scraper blade into operative contact with the conveyor belt,
- wherein the hydraulic tensioning assembly comprises a single-acting piston and cylinder assembly oriented substantially vertically and having a dead-weight accumulator biasing the piston and cylinder assembly into a return configuration.
