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.
Claims14
A tensioning arrangement for a scraper for a conveyor belt, the tensioning arrangement comprising:
- a hydraulic assembly that acts hydraulically 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 and in direct fluid communication with at least one belt scraper piston and cylinder assembly, wherein the weight applied to one of the holding piston or cylinder applies pressure on fluid contained within the hydraulic assembly, said pressure acting in the at least one belt scraper piston and cylinder assembly providing a force on the scraper determined by the weight.
A conveyor belt scraper assembly comprising:
- a scraper blade to remove materials from a conveyor belt while the conveyor belt is in use;
- a hydraulic tensioning assembly which hydraulically biases the scraper blade toward the conveyor belt,
- wherein the hydraulic tensioning assembly comprises a holding piston and cylinder assembly oriented substantially vertically and a weight together providing a dead-weight accumulator, the holding piston and cylinder assembly being in direct fluid communication with at least one belt scraper piston and cylinder assembly, wherein weight applied to one of the piston or cylinder of the holding piston and cylinder assembly applies pressure on fluid contained within the hydraulic assembly, said pressure acting in the at least one belt scraper piston and cylinder assembly providing a force on the scraper determined by the weight.
