[0002] At present, in construction earth excavation and backfilling projects, there is often no ramp for vehicles to transport earth outside or inside. In general construction technology, earth is usually lifted by manual cooperation with hooks and unhooks. With the development of automatic control, buckets with bottom opening and closing functions are used for earth lifting to save unloading time and labor costs.

[0003] In the actual situation of construction sites, in addition to conventional dry soil and stone, there is also silt formed by rainwater and groundwater. Since the water content of silt is higher than that of general dry soil and stone, in order to ensure the quality of backfill, the general work process is to first lift the silt out of the foundation pit and put it into ground equipment for filtering water, and then lift the filtered silt to the drying area for drying, and finally lift the dried soil back to the foundation pit. General lifting equipment only has basic lifting functions, and it is impossible to complete the structural and technical combination of water filtering equipment with existing lifting equipment, so that the existing equipment cannot meet the requirements of completing the initial mud and water separation operation of silt in the process of lifting earthwork, and has functional limitations and limited scope of application.
