DRILL ROD HAVING PEELING FUNCTION
Document Type and Number:
WIPO Patent Application WO/2018/032590
Kind Code:
A1
Abstract:
Provided is a drill rod having a stripping function, comprising a stripping tab (25), a stripping head (26), a drill rod housing (27), a drill-rod top cover (28), and a load-bearing rod (29); the stripping head (26) of the drill rod is equipped with the stripping tab (25); the drill rod striking downward on an object triggers a paddle (24) to be subjected to the resistance of the object and to move upward; the stripping tab (25) then pops out from a stripping installation hole (39) and strips the broken object from the point of breakage; the drill rod having a stripping function modifies the drill rod in a breaking hammer, and by means of the stripping tab (25), the breaking hammer is caused to strip away the broken object while breaking the object; thus there is a better field of view around the point of breakage, and functional performance is relatively good.
