Description

Technical Field

[0001] The utility model belongs to the technical field of civil engineering construction, and particularly relates to a material mixing device for civil engineering construction. Background Art

[0002] In the process of civil engineering construction, it is indispensable to use a mixing device. The structure of the mixing device generally includes a mixing box and a stirring device. The stirring device is arranged inside the mixing box, and a feed hopper is provided on the upper part of the mixing box. The material is added to the mixing box through the feed hopper and is stirred and mixed evenly by the stirring device. The feed hopper in the prior art is generally fixed on the mixing box. In order to facilitate feeding, the inlet of the feed hopper is usually offset to one side. Since the mixing device is a large structure, it takes a lot of manpower and material resources to move it after it is placed, and it is not convenient to move. As a result, after the mixing box is placed, the feed port is always facing one side and cannot be changed at will with the change of the feeding direction. Therefore, there are certain limitations during use. Therefore, it is necessary to propose a new mixing device for civil engineering construction. Utility Model Content

The upper cover of the circular material box is rotatably connected to a periphery of the upper opening of the circular material box through a circumferential sliding connection structure. This structure can adjust the offset direction of the feed port according to the feeding direction. It can be achieved by simply rotating the upper cover of the circular material box. After adjustment, the upper cover of the circular material box is locked, so that the direction of the feed port can be quickly and conveniently adjusted without moving the mixing box, so that the feed port can be adjusted to the most suitable orientation to facilitate adaptation to different feeding directions.
