Description

Technical Field

[0001] The utility model relates to the technical field of concrete application, in particular to a mixer capable of fully mixing steel fiber and concrete. Background Art

[0002] Concrete applications are widely used in construction, roads, bridges, tunnels, dams, water conservancy projects and other fields. In each field, the application of concrete has its unique characteristics and requirements. Therefore, when concrete is used in specific situations, mixing and stirring will require the addition of reinforcing materials and the use of mixers.

[0003] After searching, the patent number is CN217916022U, and the name is a utility model of a concrete mixer, including a mixing barrel, a driving device and a mixing device. Through research and analysis, it is found that although the vibration in the axial direction is reduced during use, the shock-absorbing protection of the mixing device is achieved, but there are still the following shortcomings to a certain extent.

[0004] For example, currently in the process of using a mixer to mix steel fiber concrete, it is impossible to perform quantitative water injection during use. In this way, when using a mixer to mix steel fiber concrete, if it does not have the quantitative water injection function, during the mixing process, the operator may inject too much or too little water due to misjudgment. At the same time, adding too much water will make the strength of the concrete fail to meet the standard, and adding too little water will make the cement unable to fully hydrate. In order to solve the above technical problems, we have designed a mixer that can fully mix steel fiber and concrete. Utility Model Content

[0013] 1. The utility model has a quantitative water injection function through the cooperation of the mounting frame, water storage tank, water level sensor, filter plate and water pump. First, the water pump is started through the controller. The water pump runs to draw water from the water storage tank and inject it into the tank body. The filter plate will block impurities in the water during extraction. When the water level drops to a set value, the water level sensor will send a command to the controller, and the controller will turn off the water pump to stop injecting water. This mechanism can control the amount of water injected according to the drop in the water level, so as to avoid excessive or insufficient water injection that affects the subsequent use strength of concrete.

After the mixing is completed, the gate assembly is started by the controller. The gate assembly rises and the mixed dry material flows into the tank from the front side of the dry mixing box. This mechanism can mix the concrete dry material and the steel fiber in advance, so that the steel fiber and the concrete can be fully mixed and stirred, and the agglomeration phenomenon caused by subsequent water addition and stirring can be avoided, so as to ensure that the finally formed steel fiber can be evenly distributed in the concrete.
