[0002] Water conservancy projects are comprehensive projects used to regulate, utilize and protect water resources. They cover facilities such as reservoirs, dams, channels, levees, pumping stations, etc., and play a key role in flood control, irrigation, power generation, water supply and ecological protection. Traditional water conservancy projects rely on manual construction and simple mechanical equipment, which are inefficient and difficult to control in terms of quality. With technological advances, modern water conservancy projects widely use high-performance concrete, intelligent monitoring systems, automated construction equipment and BIM (Building Information Modeling) technology to improve structural durability, construction accuracy and operation and maintenance efficiency.

[0003] As the core material of water conservancy projects, the production, transportation and pouring technology of concrete directly affect the quality and life of the project. The concrete production and mixing device for water conservancy projects needs to have efficient and uniform mixing capabilities, but the single-lever mixing capacity is poor, and the residual concrete inside the mixing tank is easy to affect the normal use of the mixing tank. In addition, manual cleaning of the concrete tank and manual feeding and discharging of materials are inefficient and cannot guarantee safety. Summary of the invention
