product description

Overview:

Rotary dilling buckets are mainly applied to such rock formations as higher water-bearing sandy soil, silt, clay, silty loam, gravel, cobble, and weathered soft formation. The dilling bucket can be designed in cylindri-cal type and tapered type depending on bucket diameter, type of drill rig and rock formation. The welding angle of the bucket teeth is tailored to the formation conditions. The dilling bucket bottom is made of high strength Mn plate; and the cutting elements are cassified into two types; anti-abra-sive aly flat teeth ideal for dilig soft to medium-soft soil, clay and marl formation, truncated teeth for bouldery and hard ground; and chisel teeth combined with truncated bullet teeth for alternate soft and hard formation

and well cemented gravel.

There are two types of dilling bucket bottom: single layer and double layer; and the inlet of cuttings also flls into two types: single door and double door.

The single door bucket is used to drill coarse size bouldery and cobble formation since it provides a large opening.

The double door bucket is designed for medium-size sandy soil or small size gravel formation.

Dilling bucket with single layer bottom cover; suitable for clayey formation and well cemented formation.

Dilling bucket with double layer bottom cover: suitable for sandy soil formation and poor cemented gravel formation.
