Abstract
The invention discloses a screw rod type concrete mixer tank. Mixing is carried out through a screw rod arranged in a tank body; when materials are discharged, concrete is pushed out of the tank body through a circular nut driven by the screw rod, when the materials are mixed, the tank body does not rotate, and the screw rod rotates to mix; because the screw rod is positioned in the tank body, the screw rod is used for mixing from the center of the concrete to ensure that the concrete is mixed to be more uniform in a shorter time, thereby the work efficiency of the mixer tank can be improved; when mixing, the screw rod is only needed to rotate, which reduces the driving force of mixing and saves energy sources; when the materials are discharged, by utilizing the screw rod to drive the circular nut to forcedly discharge the materials, the discharging speed is improved, the discharged materials are clean and complete, the concrete is saved, meanwhile, the number of manual clearing inner tank is reduced, the labor cost is reduced and the use ratio of concrete mixer is also improved.
