PURPOSE: A device for eliminating ice of a conveyer belt is provided to remove frozen ice in a belt efficiently when the work for removing ice frozen from snow or rainwater in the upper part of the conveyer belt transferring materials. CONSTITUTION: An elimination device of ice consists of a lifting roller part lifting a belt(1), a crushing roller part crushing ice frozen on the surface of the lifted belt, and a subsidiary belt part transferring the crushed ice. The lifting roller part consists of a cylinder(20) installed tilted in the upper part of both sides of the belt and lifting the belt, a lifting roller(30) contacted to the surface of the lower part of the belt and moving with the belt in the one side of the cylinder, and a weight pulley(70) sealing a return belt(1a) according to lifting amount. The crushing roller part consists of a crushing roller(50) crushing frozen ice as contacting on the surface of the upper part of the belt when the belt is lifted in a gap between the cylinder, and a scrapper(60) removing the crushed ice in the upper part of the belt. The subsidiary belt part consists of a subsidiary belt(10) installed in the lower part of the scrapper and transferring the removed ice, and a guide roller(40) moving with the belt as pushing the upper surface of the belt when the belt is lifted. The belt is lifted with the lifting roller by shrinking the cylinder and is stuck to the guide roller and the crushing roller. The weight pulley is raised and controls the tension of the belt according to the lifting of the belt. The frozen ice is crushed by a gear(53) formed in the crushing roller if the belt is moved. The ice, stuck to the belt, is fallen to the upper part of the subsidiary belt by the scrapper. The fallen ice is transferred by the subsidiary belt, moved by a driving motor, and removed to the outside of the suit.
