Asphalt concrete stirring device

The utility model relates to the technical field of mixing devices, and discloses an asphalt concrete mixing device which comprises a fixed support, a mixing drum is rotatably connected to the upper portion of the fixed support, a transmission mechanism is arranged below the mixing drum, and a feeding and discharging port is communicated to the lower portion of the mixing drum. A motor is started to drive a first belt pulley to rotate, under the action of a belt, a second belt pulley drives a stirring barrel to rotate, asphalt concrete in the stirring barrel is stirred, and therefore the stirring and mixing effect of the device on the asphalt concrete is improved, toxic gas in the stirring barrel is pumped into a dust removal box by starting an exhaust fan, and the dust removal effect is improved. And under the action of a spraying mechanism, dust in the gas is removed, under the action of an exhaust fan, the gas is pumped into a filter box again, toxic gas is filtered through a filter element, and the proble
