The present invention relates to a concrete mixer, and more particularly, a furnace is formed to mix concrete, and a first motor is formed at the lower end of the furnace, and a plurality of horizontal axes are connected to one end formed in the furnace. A first motor unit formed by stirring blades formed at both ends of the horizontal shaft to revolve to mix concrete formed in the furnace, and a second motor is formed at the top of the furnace, and a plurality of rotating shafts are formed at the lower end of the second motor. Rotating blades are respectively formed at the end of the rotating shaft, and the rotating blades rotate. The first motor part, which is substantially revolving, mixes concrete and rotates the concrete in detail by the rotating blades of the second motor part. By mixing, conventionally mixing concrete by the rotation of the furnace or the rotation of the blades formed inside the furnace Wheat and work accordingly without being thorough mixing also relates to a concrete mixer to solve this long running problem.

In general, the use of aggregates such as gravel, sand, cement for the manufacture of concrete is essential in the construction of civil engineering sites such as roads and bridges, and it is appropriate to consider these factors in consideration of environmental factors such as construction period or climate. It should be formulated and installed.

The degree of mixing of concrete varies according to the type and scale of the building and the structure of the building, the natural environment such as the environment and climate of the building, and the material conditions such as cement. The success requirement of the formulation is that it is well proportioned with the proper ratio of the material to be blended.

Usually the strength of concrete used in buildings is determined within the range of 180 ~ 270kg / cm2. In some cases, high-strength concrete of more than 300kg / c㎡ is required, but not used in special cases. The addition of high-strength cement or specialty chemicals also makes it possible to achieve strengths of around 700kg / cm2. Determining the strength of concrete may depend on the performance of the individual materials, but is fundamentally determined by the ratio of cement: sand: gravel, etc., especially the degree of kneading, depending on the proportion of water.

The mixed concrete is manufactured by mixing cement, sand, gravel and water in a concrete production plant, and using concrete ready-mixed concrete trucks (also called ready-mixed concrete trucks) to transport the concrete to the construction site. It is used in the field compounding by the concrete mixer for the field mixing or the concrete mixing in the field.

The concrete mixer is provided with a pair of shafts driven by the power of a motor inside the drum, and the shaft is provided with a braid for mixing the contained concrete.

In addition, the concrete mixer is fixed almost directly connected to several mixer blades to the rotating shaft of the motor fixed in the upper center of the mixer barrel and the mixer blade rotates along a predetermined rotation radius about the rotating shaft in advance This is because the concrete in the area beyond the rotation radius of the mixer blade can not be mixed and cannot be mixed with each other because the rotation radius, speed and direction are constantly constant even within the rotation radius. Problems such as poor quality concrete and poor working efficiency due to poor mixing of cement, sand and gravel have been pointed out.

In recent years, concrete mixers have been developed to allow mixers to rotate while rotating the blades. However, it is possible to contact the gears of the rotating shaft connected by the high speed motor and fluid coupling and the shafts of the mixer blades installed on both sides of the idler case. It is connected through several reduction gears, and one gear of the shaft is engaged with a fixed electric gear inside the idle case to inject oil into the idle case, resulting in frequent failures due to oil leakage and complicated construction. The service life is very short and the manufacturing cost is not popular.
