A stirring device for conveniently measuring the moisture content of concrete

technical field

The invention relates to the technical field of concrete mixing devices, in particular to a mixing device for conveniently measuring the moisture content of concrete.

Background technique

Concrete mixer is a machine that mixes cement, sand and gravel aggregate and water and mixes it into concrete mixture. It is mainly composed of mixing drum, feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device According to the nature of the work, it can be divided into batch type (batch type) and continuous type; according to the stirring principle, it can be divided into self-falling type and forced type; according to the installation method, it can be divided into fixed type and mobile type; According to the structure of the mixing drum, it is divided into pear type, drum type, double cone type, disc vertical shaft type and circular groove horizontal shaft type. With the development of concrete materials and construction technology, many new structures of concrete mixers have appeared one after another. Such as steam heating mixers, supercritical speed mixers, sonic mixers, swinging disc mixers without mixing blades, and concrete mixers for secondary mixing. Fast material, less residue, low energy consumption and less pollution. The main factors affecting the mixing quality of concrete mixers are: the structural form of the mixer, the ratio of the feeding capacity of the mixer to the geometric volume of the mixing drum, the feeding procedure and feeding position of the mixture, The configuration and arrangement of the stirring blades, the geometric angle of the arrangement, the stirring speed and the wear condition of the blade liner, etc.

In the existing life, most concrete mixing devices do not carry the corresponding concrete humidity detector, which makes it difficult for the staff to grasp the moisture content of the concrete when mixing and stirring the concrete, so that it is not convenient to control the degree of dryness and humidity of the finished concrete. In turn, it will affect the practicality of concrete. At the same time, the mixing mechanism in most vertical concrete mixers generally adopts a one-way rotation mixing method, which may cause insufficient concrete mixing and easy agglomeration, thus affecting the finished concrete. The overall quality of the concrete, and in the process of concrete mixing, it is necessary to decide whether to add water or not according to the detection results of the humidity detector, so as to realize intelligent control. Therefore, we disclose a mixing device that is convenient for measuring the moisture content of concrete to meet the needs of operators. .
