Mixing drum and multi-functional maintenance truck
The invention relates to a mixing drum and a multi-purpose maintenance truck. The mixing drum comprises a drum body, wherein an air inlet is formed in one end of the drum body; an air outlet is formed in the other end of the drum body; an air heater is arranged at the air inlet of the drum body; the drum body is sleeved with an isolating drum; an inter-layer channel is reserved between the outer wall of the drum body and the isolating drum; an air returning cover which can lead air discharged from the air outlet to the inter-layer channel is arranged outside the air outlet of the drum body; and an air collecting cover used for recovering air flowing through the inter-layer channel is arranged outside the air inlet of the drum body, and is connected with an air inlet of the air heater through a pipeline. The mixing drum and the multi-purpose maintenance truck with the mixing drum have the advantages that hot air discharged from the mixing drum can be automatically recycled, so as to improve the efficiency and reduce the energy consumption; and the whole set of the mixing drum is simple in structure and layout.
