A method and a device for removing friable coal on the narrow, long coke cakes, which is displaced from the peaks of the waves to the valleys between the waves and is beaten down on the coke cake. For this method in the device at least one scraper (12) and at least one vertically movable impact plate (13) are disposed one behind another. They are fitted with a connection (7) to a holder and the means are provided for generating a relative movement between the scraper (12) and the impact plate (13) on one side and between the scraper (12) and a stamping form on the other side. The scraper (12) and the impact plate (13) are interconnected by means of a device frame (14) so as to form a structural unit (6) that is connected to the holder. The structural unit (6) preferably can be moved along the stamping form and is equipped with a drive unit. The holder for this purpose comprises a guide that extends along the stamping form as well as a carriage or a car which can be moved on said guide and to which the unit (6) is connected with the aid of a bracket. |
