Leading Drilling Bucket Manufacturer in China

Selecting the correct size depends on the required borehole diameter and the specifications of your drilling rig, including its torque capacity, crowd force, and kelly bar size. The bucket’s diameter must match the desired hole size, and its weight and capacity must be compatible with the rig’s capabilities.

Rock drilling buckets utilize various cutting tools depending on the rock hardness and abrasiveness. Common options include tungsten carbide chisel teeth for fractured rock, conical bullet teeth for harder rock, and roller bits for very hard or interbedded formations.

Yes, wear protection is crucial, especially for rock drilling buckets and those used in abrasive soils. Adding wear plates or hardfacing to the cutting edge, body, and gate helps significantly extend the service life of the bucket and reduces costly repairs or replacements.

A soil drilling bucket with carbide teeth can handle light gravel or fractured rock to some extent, but it is not optimized for these conditions and will likely experience faster wear and reduced efficiency compared to a dedicated rock bucket.

Material is discharged by opening the bottom gate(s) of the bucket. This is typically done by a tripping mechanism on the rig or a manual latching system, allowing gravity to release the spoil collected inside when the bucket is positioned over the designated spoil pile or truck.

Regular maintenance includes inspecting and replacing worn or damaged cutting teeth/blades, checking the condition of the bucket body and gate mechanism, lubricating moving parts (like hinges and pins), and repairing any structural damage or wear on the steelwork, especially on a heavily used rock drilling bucket.

A cleanout bucket is a type of drilling bucket specifically designed to remove loose material, debris, and water from the bottom of a borehole after the main excavation is complete. They often have a flat or scraping bottom edge and may be equipped with a vacuum port or water jets for effective cleaning.

Drilling buckets are primarily designed for large-diameter boreholes, typically from 300mm upwards. For smaller diameter holes, continuous flight augers or other drilling methods are generally more appropriate and efficient.
