Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0034] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Referring to Figures 1-3 , the present utility model provides a mixing device for civil engineering projects, which is used to realize material mixing. The specific structure includes a mixing box body 1, a sealing cover 2, a stirring shaft 4, stirring blades 6, and a driving component. Among them, the mixing box body 1 is used to hold and mix materials, and the sealing cover 2 is rotatably connected to the upper end of the mixing box body 1; a plurality of stirring shafts 4 are provided, and the stirring shafts 4 are rotatably connected to the sealing cover 2.

[0036] Preferably, a hollow gear box 3 is provided inside the sealing cover 2 of the device.

[0037] The driving component includes a fixed shaft 7, a fixed gear 8, a stirring gear 5, and a support frame 9. The fixed shaft 7 is rotatably connected to the gear box 3, and the fixed shaft 7 is key-connected with a fixed gear 8; the upper ends of the stirring shafts 4 penetrate through the gear box 3 and are respectively key-connected with stirring gears 5, and these stirring gears 5 are meshed with the fixed gear 8; the support frame 9 is detachably connected to the mixing box body 1, and the fixed shaft 7 penetrates through the gear box 3 and is fixedly connected to the support frame 9.
