Description

Technical Field

[0001] The present invention relates to the field of concrete-related equipment, and particularly to a concrete mixer truck. Background Art

[0002] As the name implies, a concrete mixer truck is used to mix concrete. The mixing shaft is driven by a power mechanism to mix water, sand and lime. The mixing blades rotate to drive the materials to rotate, so as to realize the uniform rotation of the materials and finally achieve the purpose of mixing. There are many types of existing concrete mixer trucks: large concrete transport mixer trucks, small concrete mixing devices that need to be moved, and medium-sized concrete mixer trucks.

[0003] The mixing equipment in the prior art has a single structure. After mixing, the materials inside the mixing tank will adhere to the upper end. Therefore, cleaning operations are required after the later processing, and a large amount of waste water will be generated during the cleaning operation, resulting in waste of water resources. Moreover, the surface metal in the mixing tank will be adhered, which makes the thickness of the mixing tank thinner and thinner, reducing its service life. In addition, the existing medium-sized concrete mixer trucks lack power and are prone to uneven mixing. The mixing tank is parallel to the horizontal plane, and it is very difficult for the mixed materials to flow out by themselves and manpower is needed, which not only increases the manual labor but also wastes the materials in the mixing tank. The existing mixing tank is not firmly installed on the vehicle body. During the mixing process, power will definitely be generated and vibrations will occur, which easily causes the mixing tank to loosen and dangerous accidents to occur. The mixing shaft of the existing mixing tank can only rotate in one direction and cannot rotate forward and backward, which easily makes the materials unevenly mixed, resulting in waste of materials and delaying the progress of the project. Summary of the Invention
