Excavator Attachment

Sieve buckets
The excavator's Sieve buckets (also known as Skeleton buckets, sieve buckets, riddle buckets ) is a multifunctional attachment that primarily achieves material separation and screening through a grid structure on its bottom or back. Its main role is to efficiently separate large objects
such as bricks, rocks, tree roots, etc., from fine materials like soil and fine aggregates during excavation or cleaning operations.

Key Application Scenarios
Separation of Coarse and Fine Materials:Automatically filters fine materials like soil and sand during excavation, retaining large debris such as stones, tree roots, and construction waste. Rapid Sorting:Ideal for separating (construction waste) from bricks/rocks post-demolition, pre-treating aggregates in mining, and removing debris during soil improvement. Dredging & Water Treatment:River/Pond Cleaning: Grid design allows water to pass through while trapping silt and debris, enabling efficient separation of water and contaminants in hydraulic engineering projects. Soil Combing:Uses shaking or tilting motion to break up surface soil and remove hidden obstacles like roots and broken bricks, preparing the ground for (e.g., sowing, turf laying). Efficient Loading:Combines a large-capacity bucket body with screening functionality to directly collect and transport sorted materials (e.g., crushed stone, construction waste).
