Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stirring devices, in particular to a concrete stirring device for water conservancy project construction. Background Art
[0002] As we all know, water conservancy projects are projects built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flows, prevent floods and waterlogging disasters, and regulate and distribute water to meet the needs of life and production for water resources. Water conservancy projects need to build dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways and other different types of hydraulic structures to achieve their goals. Concrete, abbreviated as "concrete", refers to a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement concrete obtained by mixing, molding and curing with cement as cementitious material, sand and stone as aggregates, and water in a certain proportion. It is also called ordinary concrete. Concrete is often needed to build dams in water conservancy projects, so people need to mix and make concrete.
[0003] The existing concrete mixing device is usually open, and the stirring blades inside it are constantly rotating. The staff directly adds materials into the mixing device. Some materials are packed in bags, and the bags of materials are easily entangled with the stirring blades. In addition, when pouring the bagged materials into the concrete mixing device, the bags of materials need to be opened in advance, which makes the pouring of materials very slow, affecting the processing efficiency of concrete.
