Description

Technical Field

[0001] The utility model relates to the technical field of screw conveyors, in particular to conveying equipment for a concrete mixing station. Background Art

[0002] The screw conveyor in the concrete mixing plant is an important conveying equipment. It is mainly composed of spiral blades, conveying pipes, driving devices and other components. The working principle of the screw conveyor is to drive the spiral blades to rotate in the conveying pipe through the driving device, and use the friction between the spiral blades and the material to push the material forward along the conveying pipe to achieve continuous and uniform transportation.

[0003] In a concrete mixing station, a screw conveyor is usually used to transport raw materials such as cement, sand, and stone from a storage bin to a mixing main machine to ensure the continuity and efficiency of concrete production. For example, the Chinese utility model patent disclosed by publication number CN214091040U: a concrete conveying device for a concrete mixing station, the application sets a shell, including a conveying pipe, a connecting plate, a fixing plate, a cover plate, and a lifting lug. When in use, by opening the connecting plate connected to the conveying pipe or opening the cover plate movably connected to the conveying pipe, the waste accumulated inside can be cleaned and the equipment that needs maintenance can be repaired or replaced. However, since the overall length of the screw conveyor used in the concrete mixing station is relatively long, even if the cover plate that can be opened movably is set to facilitate the inspection of the internal structure of the screw conveyor, the internal structure of the screw conveyor is mainly a rotating shaft and a spiral conveying blade structure. Therefore, when the rotating shaft and the spiral conveying blade are inspected and replaced, the overall length of the rotating shaft and the spiral conveying blade is relatively long, and the rotating shaft and the spiral conveying blade cannot be conveniently disassembled and removed from the screw conveyor.
