A cleaning mechanism for use with a closed loop conveyor belt supported in continuous traversing fashion. The mechanism includes a housing for supporting the belt, a frame mounted to the housing proximate to the belt. A drive shaft extends between spaced apart locations of the frame and includes a pair of head sprockets adapted for supporting the belt at a selected location. A motor is engaged to an input end of the drive shaft. A counter weighted comb element is pivotally secured to the frame, an upper angled combed edge of the comb element arrayed in spatial non-contacting fashion with a traversing exterior of the belt for capturing elongated shaving debris suspended from the belt. A slave shaft extends between additional spaced apart location of the frame and which is rotated via a linkage with the drive shaft. Pluralities of bristles extend from the slave shaft in a cylindrical arrangement such that selected width extending portions of the bristles are arranged in successive contact with the belt upon rotation of the slave shaft in order to scrub the belt.

A self cleaning apparatus for a belt conveyor. The self cleaning apparatus comprises a rotor positioned adjacent to an outer side edge of the return conveyor portion of the belt, and a rotor housing received about the rotor. The rotor housing has an intake and a discharge, with the intake receiving and directing material on the upper surface of the return conveyor portion to the rotor as the belt rotates. Rotation of the rotor causes the directed material to be propelled by the rotor through the discharge and to be deposited onto the upper surface of the loaded conveyor portion.

A conveying device with a revolvingly led, extensively extended conveying element, which forms a conveying section with a conveying surface, and a return section, which is arranged below the conveying section. The conveying element is deflected in each case in two head-end regions, which are spaced from one another along the conveying direction. A wiper device for wiping foreign objects led along on the conveying surface of the conveying element is arranged in the front head-end region, in which the conveying element is deflected from the conveying section into the return section. The wiper device includes a wiper unit with a receiving blade, which runs transversely to the conveying direction, as well as a wiper blade, which is mounted on the wiper unit and forms a flexible wiper lip projecting toward the conveying element beyond the receiving blade.

[Object] To provide a building material manufacturing apparatus that is suitable for suppressing clogging of a screen that screens a building raw material. [Solution] A building material manufacturing apparatus X1 includes at least a screen part 10 and a cleaning mechanism part 40. The screen part 10 includes at least one screen sheet 12 that has an inclination and that has a screen mesh. The cleaning mechanism part 40 includes a scraping part 40a. When the apparatus operates in a building material manufacturing mode in which a building raw material M is supplied to the screen sheet 12 and the screen sheet 12 is performing a wave motion, the scraping part 40a is separated from the screen sheet 12, and, when the apparatus operates in a cleaning mode in which the building raw material M is not supplied to the screen sheet 12 and the screen sheet 12 is not performing a wave motion, the scraping part 40a rotates in contact with the screen sheet 12.
