The lower U-shaped groove formed by the lower U-shaped structure is the return chain groove of the slag scraper. The transmission device is installed in the slag discharge section of the main engine, the tensioning device is installed in the chain entry section of the main engine, the guide wheel device is installed in the slag storage section of the main engine, the cast stone wear-resistant system is laid on the bottom of the upper and lower U-shaped grooves of the main engine, and the chain of the scraper chain device is installed On the sprocket of the transmission device, the sprocket of the transmission device drives the scraper chain device and moves under the guidance and positioning of the guide wheel device. The upper U-shaped groove of the slag storage section of the main engine cooperates with the boiler slag hopper, and the ash and slag of the boiler are discharged from the slag. The bucket falls into the upper U-shaped groove of the slag storage section of the slag scraper, and the transmission device drives the scraper chain device to move to remove the ash from the upper U-shaped groove of the slag storage section of the slag scraper, passes through the slag discharge section of the main machine, and then Return from the return chain slot of the slag extractor. However, since the upper U-shaped groove of the slag storage section of the main engine of the known scraper slag removal machine technology cooperates with the boiler slag hopper, when the width dimension parameter of the boiler slag hopper changes, the width dimension of the U-shaped groove of the slag storage section of the slag removal machine main engine The parameters must also be changed accordingly, so the width dimension parameters of the U-shaped grooves of the slag discharge section and the chain entry section of the main engine are the same as it and also change accordingly, which leads to the transmission device, tensioning device, and scraper installed on the main engine body. The plate chain device and the cast stone wear-resistant system must be changed, and must be redesigned and manufactured. The components of the scraper slag machine cannot be used universally and standardized within a certain range, which also makes the development, design and manufacture of the scraper slag machine difficult. It must be customized for a certain type of boiler, and the production cycle of R&D, design and manufacture is long, difficult and costly.
