Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete mixing, in particular to a material discharge mechanism of a concrete mixing tank. Background Art
[0002] When producing concrete, a concrete mixing tank is needed. Sand, gravel, cement and water are added into the mixing tank, and the mixing tank is started so that the mixing tank can fully mix and blend the sand, gravel, cement and water together to form concrete.
[0003] A concrete mixing tank disclosed in the authorization announcement number CN113400478B includes a bracket, a stirring device is arranged inside the bracket, a power source is arranged at the left end of the stirring device, and the left end of the stirring device is fixedly connected to the right end of the power source, a discharge baffle is arranged at the right end of the stirring device, and the right end of the stirring device is fixedly connected to the left end of the discharge baffle, a support frame is arranged at the bottom of the right end of the bracket, and the bottom of the right end of the bracket is fixedly connected to the top of the support frame, and a driven wheel is arranged at the bottom of the right end of the stirring device. The concrete mixing tank solves the problem that the existing concrete mixing tank includes a tank body and main blades spirally arranged along the inner wall of the tank body, with a total of two sets of main blades, which are similar to double threads with the same rotation direction and a phase angle difference of 180 degrees. Since the main blades are straight blades, the secondary mixing function is very weak, which reduces the homogeneity of the concrete and is prone to segregation. A discharge slide is provided at the discharge end of the mixing tank. When the mixing tank is reversed, the mixed concrete can be discharged through the discharge end and the discharge slide, thereby completing the discharge. However, this discharge method is difficult to achieve accurate discharge. When using an ash barrel for receiving materials, since the ash barrel is relatively small and cannot be accurately discharged, it is easy to directly fill the ash barrel, thereby causing leakage.
[0004] Therefore, we propose a material discharge mechanism for a concrete mixing tank to solve the above problems. Utility Model Content
