Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to mixing equipment for cement mortar. Background Art

[0002] Cement mortar specimens are a common performance test piece in the engineering field, used to test the flexural and compressive strength of Portland cement, ordinary Portland cement, slag Portland cement, fly ash Portland cement, composite Portland cement, and limestone Portland cement. When making cement mortar specimens, corresponding mixing equipment will be used to evenly mix the cement mortar raw materials.

[0003] When optimizing the existing cement mortar mixing equipment, most of the optimization is reflected in the effect of the device on fixing the mixing barrel. For example, the Chinese utility model patent with publication number CN202321715213.3 discloses a "mixing equipment for preparing cement mortar test blocks". The utility model patent is equipped with an adjustment lifting device, and the movable seat is radially moved by rotating the screw to adjust the position of the barrel seat. Different types of mixing barrels can be placed and interference during operation can be avoided. The first sprocket is driven by a motor to rotate, so that the second sprocket drives the workbench to rotate, so that the mixing barrel and the mixing fan blades rotate in the opposite direction to accelerate mixing. While improving the versatility of the equipment, it avoids interference between the mixing barrel and the outer wall of the equipment and prevents tipping. The mixing barrel can also rotate in the opposite direction to accelerate the uniform mixing of materials.

[0004] Although the above method has certain advantages in terms of improvement, it still has certain disadvantages: if the bottom of the stirring rod is not set in an inclined shape, the cement, water and sand and gravel at the bottom will not be stirred, which will cause problems in the quality of the produced cement mortar.
