Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment for building projects, in particular to a loader for building projects. Background Art

[0002] A loader is a type of earthwork machinery widely used in construction projects such as highways, railways, buildings, hydropower stations, ports, and mines. It is primarily used for loading bulk materials such as soil, sand, lime, and coal, and can also perform light excavation of ore and hard soil. By equipping it with various auxiliary devices, it can also perform bulldozing, lifting, and concrete mixing operations.

[0003] In situations where the construction site is not fixed, in order to avoid repeatedly moving the fixed concrete mixer, a concrete mixing hopper is installed on the loader's boom. By installing the concrete mixing hopper, a series of work processes such as concrete mixing, transportation, and unloading can be completed at one time. However, the drive motor on the existing concrete mixing hopper is exposed to the outside. When loading sand and gravel into the loader hopper, the motor is easily damaged due to obstruction by the sand and gravel. During the process of mixing concrete with the mixing hopper, an appropriate amount of water needs to be added to the mixing hopper. When working in special situations where there is no water source, the normal progress of the work is affected. Finally, after the work is completed, the hopper and the dragon drum need to be cleaned immediately to prevent the concrete from sticking to the inner wall of the hopper. When there is no water source, the hopper and the dragon drum need to be cleaned manually with professional cleaning tools. Manual cleaning is slow and inefficient. Utility Model Content
