Description

Technical Field

[0001] The present application relates to the field of construction, and in particular to a portable cement mixing device. Background Art

[0002] Cement, also known as cement, red lime, red soil, etc., is a powdery hydraulic inorganic cementitious material that solidifies and hardens when mixed with water. It is usually not used alone, but is used to combine with sand and gravel (aggregate) to form mortar or concrete. The main raw material of cement is lime or calcium silicate. After hardening, it can resist the erosion of fresh water or salt water. As an important cementitious material, it is widely used in civil construction, water conservancy, national defense and other projects.

[0003] In the construction field, cement is widely used in the construction of houses and buildings, so a large amount of cement and water and other materials need to be prepared and mixed into mortar or concrete for use. Common mixing devices are usually composed of a motor, a mixing shaft and a mixing blade. Some mixing devices are equipped with a lifting device to drive the motor to lift and lower to adjust the height of the mixing blade. The motor output shaft and the mixing shaft are coaxially fixed, and the mixing blade is fixed on the outer wall of the mixing shaft. The motor drives the mixing shaft to rotate to drive the mixing blade to mix the mixture of cement and water. This mixing device is inconvenient to move and is relatively bulky, and needs to be improved. Utility Model Content
