Description

Technical Field

[0001] The utility model belongs to the technical field of concrete mixing, in particular to a concrete feeding and mixing integrated machine. Background Art

[0002] Concrete is a building material made by mixing cement, sand, gravel (aggregate), and water in a specific proportion, then mixing, pouring, vibrating, shaping, and curing to harden. Concrete has excellent strength and durability and is widely used in buildings, bridges, roads, tunnels, and water conservancy projects.

[0003] Before using concrete, the raw materials need to be mixed evenly in a certain proportion to meet the construction requirements. Currently, there are some concrete mixing equipment on the market, such as a concrete mixer with a convenient loading function and a publication number of CN213500047U on the Chinese Patent Network. This concrete mixer can realize the automation of concrete material loading, save manpower and improve work efficiency, but there are some defects and deficiencies that need to be improved: (1) Although some existing concrete mixing equipment has an automatic loading function, the loading points are too concentrated, making it difficult for the raw materials to be evenly distributed when entering the mixing drum, resulting in the raw materials not being fully mixed during mixing, which in turn affects the quality of the concrete; (2) Due to the structural design of some existing concrete mixing equipment, the raw materials are easily overflowed or scattered during the loading process, resulting in material waste and increasing the difficulty of on-site cleaning; (3) Some existing concrete mixing equipment lacks effective dust prevention measures and is prone to generating a large amount of dust during the loading process, which not only causes environmental pollution and affects the health of operators, but also increases equipment wear and reduces its service life. Therefore, in response to the above problems, the concrete loading and mixing integrated machine provided by the present invention is of great significance. Utility Model Content

[0004] The utility model provides a concrete feeding and mixing integrated machine, which can introduce concrete raw materials into the mixing tank for mixing through the feeding mechanism, and can introduce raw materials into the mixing tank from multiple angles through the dividing mechanism to realize multi-point feeding, thereby ensuring that the raw materials can be evenly distributed when entering the mixing tank, and effectively avoiding the raw materials from being fully mixed during mixing; the closed feeding mechanism and the dividing mechanism can prevent the concrete raw materials from being blown away or overflowing during the feeding process, and when the amount of raw materials entering the dividing trough is large, the overflow cover can play a blocking role to prevent the raw materials from overflowing or scattering from the dividing trough; the multiple dust-proof nets on the dust-proof plate can effectively absorb the dust raised during the feeding process to prevent the dust from spreading into the air, and the water mist formed by the dust suppression mechanism can reduce the dust concentration in the air, so as to further reduce the spread of dust and improve the working environment.
