Description

Technical Field

[0001] The invention relates to the technical field of mixers, in particular to a mortar mixer with adjustable viscosity. Background Art

[0002] Mortar mixer equipment can meet the production needs of dry-mix mortar, dry-mix materials, dry-mix adhesives, etc. with different performance requirements, such as putty powder, dry-mix paint, masonry mortar, plastering mortar, mortar required for insulation systems, decorative mortar and other dry-mix mortars; and has many advantages such as small footprint, low investment, quick results and simple operation.

[0003] Mortar is composed of water, sand and cement. Cement mortar can be formed by mixing water, sand and cement. When the strength of cement mortar with different viscosities needs to be tested, it is necessary to mix water, sand and cement with different contents. Therefore, during the experiment, it may be necessary to add water or sand or cement multiple times so that mortars with various viscosities can be sampled.

[0004] Existing mortar mixers mostly use a stirring rod to stir from the center of the mixing tank during stirring. When other raw materials are added during the stirring process, they are generally added toward the outside of the mixing tank. At the same time, if a large amount of raw materials are added at a single location, it may cause local accumulation of the raw materials, requiring a long time of stirring to achieve uniform stirring.
