Description
Technical Field
[0001] The utility model relates to the technical field of concrete mixing equipment, and particularly relates to a concrete mixer with a cleaning structure. Background Art
[0002] A concrete mixer is a mechanical device specifically used for mixing concrete materials. It usually includes a rotating mixing barrel, which is equipped with mixing blades inside. The mixing barrel is driven by an electric motor to rotate, so that the concrete materials are fully mixed inside the mixing barrel to achieve the predetermined uniformity and quality.
[0003] When discharging the concrete after mixing is completed, due to the excessive gap between the mixing blades and the barrel wall, the concrete adheres to the wall during the mixing process. Since the concrete itself has a certain viscosity, after the discharging is completed, part of the concrete remains on the inner wall of the mixer and cannot be cleaned. Therefore, the Chinese utility model patent with the publication number CN209794186U: a concrete mixer convenient for cleaning. This application is provided with a cleaning plate covering the inner surface of the mixing tank and a detachable connection between the cleaning plate and the mixing tank, which is convenient for cleaning the concrete attached to the cleaning plate. However, when cleaning the inner surface of the mixing tank, since the concrete remaining on the inner surface of the mixing tank needs to be cleaned every time after the concrete mixing is completed to prevent the concrete from drying and becoming impossible to clean, this application needs to frequently disassemble and assemble the cleaning plate, making the cleaning process cumbersome.

[0022] As Figure 4 shown, a mounting groove 13 is opened in the mounting plate 10, a first jack 14 is opened on one side inside the mounting groove 13, and a connecting shaft 12 is movably installed inside the mounting groove 13. An end cover 15 is threadedly connected to the side of the mounting groove 13 far from the first jack 14, and a compression spring 16 is also inserted and installed inside the mounting groove 13. With the aid of the mounting groove 13 opened in the mounting plate 10 and in cooperation with the connecting shaft 12, the compensation plate 11 can be movably installed on one side of the two mounting plates 10;
[0023] AsFigures 2 - 5 As shown, a limit ring 17 is fixedly installed on the outside of the connecting shaft 12. Two snap rings 18 are also clamped on the outside of the connecting shaft 12. A connecting seat 22 is arranged on the connecting shaft 12 between the two snap rings 18. A second jack 23 is opened in the connecting seat 22. The connecting seat 22 is inserted and installed on the connecting shaft 12 between the two snap rings 18 through the second jack 23. The connecting shaft 12 is inserted and installed in the installation groove 13 through the limit ring 17, and the compression spring 16 supports the connecting shaft 12.
