Drilling buckets are mainly used for drilling water-bearing sandy soil, sludge, clay, muddy sub clay, sandy gravel, cobble, and weathered soft formation. The bucket can be designed into cylindrical type and conical type according to bucket diameter, type of drilling rig and soil conditions. The opening and closing device can be operated manually, mechanically or mixed manner. The welding angle of bucket teeth can be designed according to formation conditions. The bottom cover is made of high-strength Mn plate, and the cutting edge includes single-layer type and double-layer type; the soil inlet also includes single-bottom type and double-bottom type. Unimate drilling buckets are mainly divided into three types: 1-Clay Drilling Buckets 2-Rock Drilling Buckets 3-Cleaning Buckets 1) Clay Drilling Buckets There are two categories of clay drilling buckets: a)Single Cut Clay Bucket b)Double Cut Clay Bucket Drilling Diameter Range: 500~2500mm Barrel Length: 1000~1500mm Main Applications: i)These buckets are suitable for drilling in clay, silt and loose to medium dense sand and gravel. ii)Single cut buckets are recommended up to coarse gravel. iii)Double cut buckets are mainly used for bigger diameter uncased boreholes. iv)Single bottom buckets are used for clay layer and sticky formation. Features: 1-Cylindrical barrel & conical barrel(depends on customer demand) 2-Fish-tail Pilot 3-Throughout ventilation hole 4-Hard facing strips for wear protection 5-Kelly box size as per customer demand 2) Rock Drilling Buckets There are two categories of rock drilling buckets: a)Single Cut Rock Bucket b)Double Cut Rock Bucket Drilling Diameter Range: 500~2500mm Barrel Length: 1000~1500mm Main Applications: i) Rock buckets are suitable for drilling in medium to weak rock and in very dense sand and gravel. ii) Single cut buckets are recommended up to coarse gravel. iii) Double cut buckets are recommended for secant piles and bigger diameters uncased boreholes. Features: 1-Throughout ventilation hole 2-Rock Pilot 3-Hard facing strips for wear protection 4-Kelly box size as per customer demand 3) Cleaning Bucket Cleaning Diameter Range: 500~2500mm Barrel Length: 1000~1500mm Main Application: Cleaning bucket is used for cleaning the bottom of borehole. Steel pallet, wooden case.
