Description

Technical Field

[0001] The utility model relates to the technical field of mixer trucks, in particular to an end cover of a sealed tank of a mixer truck. Background Art

[0002] The working environment of industrial and mining tunnels places restrictions on product dimensions, limiting the volume of the tank. This also leads to slow speeds due to the inherently low volume. Small volumes and slow speeds can severely impact project efficiency. Using sealed tanks can increase the volume of a single transport, thereby increasing project efficiency. However, the feed and discharge systems of sealed tanks are typically integrated with the tank's outlet, rotating with the tank. Therefore, the tank's rotation as the truck moves forward can easily affect the stability of the feed and discharge structure. Therefore, the development of a sealed tank end cap for truck mixers is necessary to address this issue. Utility Model Content
