[0005]

According to the present invention, an endless main transport belt is stretched between a tail pulley and a head pulley. Corrugated flanges are provided on both sides of the main transport belt over the entire length of the main transport belt. The transported object is inserted between the corrugated flanges on both sides, and the transported object is directed to the transported material discharge section on the head pulley side. In the conveyor belt device configured to be conveyed, a cleaner for preventing seizure is provided at a position on the lower side in the moving direction of the main conveyor belt close to the conveyed object discharge part on the head pulley side of the conveyor belt device, and this seizure prevention is performed. The cleaner has a swing arm having one end pivotally supported on a mounting portion provided on a frame of the conveyor belt device so as to be rotatable around a horizontal axis. A scraper attached to the inking arm via a bracket, and a spring interposed between the swing arm and the frame to urge the scraper to contact the surface of the main transport belt, Further, the scraper has a V-shaped recess, and the V-shaped recess is oriented in a direction opposite to the traveling direction of the main transport belt, and is configured to be in line contact with the surface of the main transport belt over the entire scraper. The gist of this is. Further, the present invention is characterized in that the scraper is formed in a shape substantially like an arrow blade by bending a metal so as to have two V-shaped concave portions in front and rear.

[0006] With this configuration, the sediment adhering to the surface of the main conveyor belt scraped by the scraper by the rotation of the main conveyor belt is moved to the inside of the V-shaped recess, that is, to the center in the width direction of the main conveyor belt. The main conveyor belt which is close to the conveyed object discharge portion of the conveyor belt device does not allow the sediment scraped by the scraper to enter the concave side of the corrugated flange. The detached sediment can be dropped and removed at a position on the lower side in the moving direction, that is, a predetermined position near the head pulley, and the sediment of the transferred object can be prevented. As a result, the sediment falls in an unexpected place such as the conventional one, which leads to a personal injury or a problem of contaminating the surrounding environment. If left as it is, the space surrounded by the corrugated flange and the plate-shaped horizontal member becomes narrow, and the problem of reduced transport efficiency at once can be solved by reducing the transport amount of the transported object and reducing the transport efficiency. It becomes possible.
