Embodiment Construction

[0024] Below in conjunction with accompanying drawing, the present invention is described in further detail, as shown in the figure:

[0025] A concrete mixing device provided by the present invention includes a mixing drum 1, a central mixer, a first planetary mixer, a second planetary mixer and a driving mechanism;

[0026] The central agitator is arranged coaxially with the mixing drum 1, and the central agitator, the first planetary agitator and the second planetary agitator are arranged in parallel and are all connected to a driving mechanism, and the driving mechanism drives the central agitator to rotate around the mixing drum. 1, the drive mechanism also drives the first planetary agitator to revolve around the axis of the mixing drum and to rotate around its own axis of rotation;

[0027] The structure of the first planetary agitator and the central agitator is the same, the central agitator includes a rotating shaft 16 and a helical stirring blade arranged at the mid...

Abstract

The invention provides a concrete stirring device. The concrete stirring device comprises a stirring cylinder, a central stirrer, a first planetary stirrer, a second planetary stirrer and a driving mechanism, wherein the central stirrer and the stirring cylinder are coaxially arranged, the central stirrer, the first planetary stirrer and the second planetary stirrer are arranged in parallel and are all connected with the driving mechanism, the driving mechanism drives the central stirrer to rotate around the axis of the stirring cylinder, and the driving mechanism further drives the first planetary stirrer to revolve around the axis of the stirring cylinder and rotate around the rotating axis of the first planetary stirrer. According to the concrete stirring device, concrete in the stirring cylinder can be fully stirred, and no stirring dead angle exists in the stirring process, so that the uniformity of the final concrete can be effectively ensured, and the building quality is ensured.

Description

technical field [0001] The invention relates to a mixing device, in particular to a concrete mixing device. Background technique [0002] Concrete is a commonly used building material. Concrete is formed by mixing sand, cement, gravel and water. Concrete mixing is realized by a mixer. The existing concrete mixer has the following defects: during the concrete mixing process, the The concrete near the stirring paddle can be fully stirred, but the concrete far away from the stirring paddle cannot be fully stirred, especially the coagulation near the side wall of the container of the mixer, often deposits, which seriously affects the quality of the concrete . [0003] Therefore, in order to solve the above-mentioned technical problems, it is urgent to propose a new stirring device. Contents of the invention [0004] In view of this, the object of the present invention is to provide a concrete mixing device, which can fully mix the concrete in the mixing container, and there ...
