[0002] In the field of construction engineering, mixed sand and gravel are one of the main components of concrete. During concrete preparation, sand and gravel are mixed with cement, water, and other additives to form a concrete slurry. Sand and gravel provide aggregate for concrete, increasing its strength and stability. Mixed sand and gravel are widely used in supporting structures in construction projects, such as concrete columns, walls, and beams. These structures require sufficient strength and stability, and mixed sand and gravel, as aggregate, can increase the load-bearing capacity and durability of concrete, ensuring the safety of the structure.
[0003] Currently, sand and gravel mixing devices typically require mixing sand and gravel with water in a certain ratio. However, existing devices usually only allow water to be added at fixed locations, necessitating continuous mixing to ensure thorough mixing of water and sand, thus reducing mixing efficiency. Furthermore, mixing efficiency is also reduced when sand and gravel of varying sizes are mixed before the device is activated. Utility Model Content
