[0020] Example: Figures 1-4 As shown, the utility model provides a technical solution: an asphalt concrete mixing device with a dust recovery function, comprising a base plate 1, a mixing barrel 3 fixedly connected at the top of the base plate 1 near the center of one side, a feed port 33 being provided at the top of the mixing barrel 3 near the center, a chute 34 being symmetrically provided at the top of the mixing barrel 3 and near the feed port 33, a cover plate 35 being slidably connected between the two chute 34, and the cover plate 35 being adapted to the feed port 33, a vertical plate 2 being fixedly connected at the top of the base plate 1 and near the center of the other side, an L-shaped plate 21 being fixedly connected at the top center of one end of the vertical plate 2 near the mixing barrel 3, a hot air blower 22 being fixedly connected to the top of the L-shaped plate 21, a connecting pipe 1 23 being fixedly connected to one end of the hot air blower 22, a valve 24 being fixedly connected to a connecting pipe 25 at the other end, and a connecting pipe 2 25 being fixedly connected to the mixing barrel 3.

[0021] An inclined rod is fixedly connected to the bottom end of the L-shaped plate 21 near the center, and the other end of the inclined plate is fixedly connected to the vertical plate 2.

[0022] By adopting the above technical solution, an oblique rod is provided at the bottom end of the L-shaped plate 21 in order to support and fix the L-shaped plate 21 .

[0023] A stirring rod 32 is rotatably connected to the center of the top end of the mixing barrel 3.

[0024] By adopting the above technical solution, a stirring rod 32 is provided inside the mixing barrel 3 in order to cooperate with the stirring blades to achieve the effect of fully mixing the interior.

[0025] The outer ring of the stirring rod 32 is fixedly connected with a plurality of stirring blades, and the plurality of stirring blades are evenly distributed.

[0026] By adopting the above technical solution, the stirring blades are provided to cooperate with the stirring rod 32 to achieve the effect of mixing the inside of the mixing barrel 3.

[0027] A motor 31 is fixedly connected to the center of the top of the mixing barrel 3 , and an output end of the motor 31 passes through the mixing barrel 3 and is fixedly connected to a stirring rod 32 .

[0028] By adopting the above technical solution, the motor 31 is operated, thereby causing the fixedly connected stirring rod 32 to rotate.

[0029] A top plate 36 is fixedly connected to the center of the top end of the cover plate 35 .

[0030] By adopting the above technical solution, a top plate 36 is provided on the top of the cover plate 35 in order to facilitate the movement of the cover plate 35 .

[0031] An electric cylinder 37 is fixedly connected to the top of the mixing barrel 3 near the top plate 36 , and the output end of the electric cylinder 37 is fixedly connected to the top plate 36 .

[0032] By adopting the above technical solution, the electric cylinder 37 is operated, so that the fixed top plate 36 drives the cover plate 35 to move horizontally.

[0034] By adopting the above technical solution, a discharge port is provided at the bottom end of the mixing barrel 3 in order to facilitate the discharge of the material.

[0035] Working principle: When the material needs to be stirred, the material to be mixed is added to the mixing barrel 3 through the feed port 33, and then the electric cylinder 37 is operated, so that the top plate 36 fixedly connected drives the cover plate 35 to move horizontally under the action of the two slide grooves 34. When the cover plate 35 moves above the feed port 33, the feed port 33 is sealed, thereby solving the problem that dust will float out through the feed port 33 and be inhaled by the workers, making it difficult to ensure the health of the workers.

[0036] When it is necessary to clean the inside of the mixing barrel 3, clean water is added to the mixing barrel 3 and the mixing barrel 3 is cleaned. After the mixing barrel 3 is cleaned, the inside of the mixing barrel 3 will remain moist. Then the hot air blower 22 is operated and the valve 24 is opened, so that the hot air can be transmitted to the inside of the mixing barrel 3 under the cooperation of the connecting pipe 1 23 and the connecting pipe 2 25, thereby accelerating the evaporation of water inside the equipment. The valve 24 is set to prevent the moisture or cleaning liquid inside the mixing barrel 3 from moving into the connecting pipe 1 23 and damaging the hot air blower 22, thereby solving the problem of having to wait for a long time for natural drying after cleaning the inside of the equipment, which will extend the downtime of the equipment.

[0037] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
