[0002] Concrete can be referred to as concrete. It refers to an engineering composite material formed by cementitious materials. Usually concrete uses cement as a cementitious material, and sand and stone as aggregates, which are mixed with water in a certain proportion and then stirred into cement concrete. It is often used in construction and civil engineering. It is a widely used material. Concrete mixing is an operation method of mixing cement, lime, water and other materials and stirring them evenly. There are generally two types of mixing methods: manual mixing and mechanical mixing. Among them, mechanical mixing is divided into self-falling mixing and forced mixing. For different mixing materials, the mixing structure is also different.
[0003] However, the prior art still has the following problems:
[0004] First of all, most mixing devices have uneven mixing during the mixing process, and the mixing force is not strong enough, causing the mixer to get stuck or the mixing blades to be damaged. When faced with harder and denser concrete, the mixing is not sufficient and the mixing is not stable enough, resulting in the concrete being unable to form.
[0005] Secondly, after the concrete mixing is completed, manual discharge work needs to be carried out immediately, which increases the workload of the workers after mixing, and it is impossible to effectively control the flow rate of the falling concrete. In addition, most mixing devices are inconvenient to move and cannot achieve timed peak unloading operations.
