Abstract
A heated conveyor belt cleaner is provided including a support shaft positioned adjacent to the belt to be cleaned and generally transverse to the belt's direction of travel, an electric resistance heating element is disposed within the support shaft, a heat conducting medium is disposed between the support shaft and the heating element to effectively conduct heat from said heating element to the support shaft, a mounting sleeve concentrically surrounding the support shaft for mounting a belt scraper element on the support shaft, at least one belt scraper element connected to the mounting sleeve and, through the mounting sleeve, to the support shaft, such that heat generated within the support shaft is communicated from the support shaft through the mounting sleeve to the scraper element to heat the scraper element for effective removal of adherent materials from the conveyer belt. A temperature sensor communicates the temperature of the scraper element to a thermostat which regulates the electric resistance heating element to provide a uniform preselected temperature at the scraper element.
