Abstract
A silo bin drilling system used for unclogging bulk material in a silo bin. The drilling system includes a hydraulic drill with drill motor. The drill is mounted above an access hole in a top portion of the bin. An access door in a bottom of the bin is used for forming a lower bin cavity in the material. The system also includes a pipe string. The pipe string is attached to a pipe string motor. A bottom of the pipe string is attached to a drill bit with foldable blades. The drill bit is used for drilling a cavity access hole through the clogged bulk material into the lower bin cavity. The pipe string motor then moves the drill bit with unfolded blades upwardly through the material drilling a large diameter raise hole until the clogged material collapses in the bin.
Claims13
A method of unclogging clogged bulk material stored in a silo bin, the steps comprising:
- drilling downwardly a small diameter cavity access hole from a top of the silo bin through the clogged bulk material and into a lower bin cavity, the lower bin cavity disposed below the clogged bulk material;
- and
- drilling upwardly a large diameter raise hole in the clogged bulk material, the large diameter raise hole sufficient in size to allow the clogged bulk material to cave in and around the sides of the large diameter raise hole as the raise hole advances upwardly through the bulk material.
A method of unclogging clogged bulk material stored in a silo bin, the steps comprising:
- opening an access door in a bottom of the silo bin and digging out a lower bin cavity disposed below the clogged bulk material;
- using a hydraulic drill and drilling downwardly a small diameter cavity access hole from a top of the silo bin through the clogged bulk material and into the lower bin cavity;
- and
- using the hydraulic drill and drilling upwardly a large diameter raise hole in the clogged bulk material, the large diameter raise hole sufficient in size to allow the clogged bulk material to cave in and around the sides of the large diameter raise hole as the raise hole advances upwardly through the bulk material.
