Description

Technical Field

[0001] The present application relates to the technical field of drilling auxiliary devices, and more specifically, to a pipeline drilling tool. Background Art

[0002] In the prior art, when a silo storing solid particulate materials is cleared, compressed air or water is transported to the working unit through a pipeline, forming a jet at the nozzle end hole, generating strong kinetic energy to act on the materials in the silo, causing expansion, sweeping, cutting, stirring and other effects, so that the agglomerated parts become collapsed and loose, and the material drop channel is restored to a clear state. The number of working units is one of the key factors affecting the efficiency of silo clearing.

[0003] Sometimes, insufficient number of work units planned in the early stage will lead to poor warehouse clearance results. At this time, adding work units requires drilling holes in the annular pipe or straight pipe installed on the silo. Since the pipe diameter is relatively small and the pipe wall is relatively thick, it is easy to slip when drilling directly with an electric drill. In addition, the location where the pipe is installed is usually very narrow. It is difficult to fix it with a bench drill and there is not enough space, making secondary drilling very inconvenient. In short, the pipe drilling solution in the existing technology is inconvenient to operate and the drilling accuracy is also poor. Utility Model Content
