The utility model discloses a conveying and slag cooling integrated machine. The machine comprises a head portion (1), a middle portion (2), a tail portion (3), a power system (4) and a cooling system (5), wherein the middle portion (2) forms closed cooling water channels (6) through partitions, water supply connectors (7) of the coolant water channels (6) are connected with a water inlet position of the cooling system (5), and water discharge connectors (7) of the coolant water channels (6) are connected with a water outlet position of the cooling system (5). The conveying and slag cooling integrated machine is provided with dual functions of a slag cooler and a scraper conveyor, slag is fed from the tail portion and conveyed to the head portion through the middle portion, and during the process, the slag is cooled gradually. The machine has the advantages that the processing capacity is high, the structure is simple, the discharged slag temperature is low, the performance is stable, the maintenance is easy, a next-level conveying device is well protected, space needed by equipment is saved, and fault points are reduced due to the integration of the conveying and the slag cooling.
