Concrete mixer

Abstract

The invention disclose a concrete mixer which is high in mixing efficiency, not prone to adhesion, capable of saving electricity and convenient to clean. The concrete mixer comprises a mixing drum body, a feeding port is formed in the upper end of the mixing drum body, a discharging port is formed in the bottom of the mixing drum body, a valve used for controlling opening and closing of the discharging port is arranged on the discharging port, wherein a rotating shaft is rotatably arranged in the stirring cylinder body in a manner of penetrating through the stirring cylinder body, a sealing device is arranged between the rotating shaft and the stirring cylinder body, a plurality of stirring fins are uniformly distributed on the rotating shaft, a driving device for driving the rotating shaft to rotate is arranged on the stirring cylinder body, the interior of the rotating shaft is of a hollow structure, a heating device for heating the rotating shaft and the stirring fins is arranged in the rotating shaft, a timing device for controlling the driving device to stop working at regular time is arranged on the stirring cylinder body, and a controller for controlling the driving device,the heating device and the timing device to work is arranged on the stirring cylinder body.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a concrete mixer. Background technique [0002] At present, the concrete mixer is a kind of machine commonly used on the construction site. Its function is mainly to use cement as the cementitious material, sand and stone as the aggregate, and mix it with water in a certain proportion to make concrete mixing material. There are certain disadvantages in existing concrete mixers. One is that the stirring rods of existing mixers are easily stuck by concrete during mixing, which affects the mixing efficiency of the mixer and is inconvenient to clean; the other is that the mixing of existing concrete mixers The work is shut down through human judgment, which leads to high cost of use due to the waste of electricity, which does not meet the guidelines of energy conservation and emission reduction. Contents of the invention [0003] Therefore, in view of the above prob...
