Screw axis connecting device of screw conveyor

摘要

(57) Abstract Objective Joint of the screw axis being easy, furthermore in the midst of useThe contact which does not have the fact that the volt/bolt nut loosens is offered. Constitution The header which is propelled to the earth by the small caliber tube propulsion machineThe screw axis of the screw conveyer which is provided on the diameter inside of pipeIn the contact, the screw axis 1 which it should joint mutually,On the one hand fit section 1of a multilateral form of 2, in addition on the other hand description above InlayingConjunction section 1a to provide the coupling section 2b which is fit unrestricted, these fit sectionsForming volt/bolt hole 1b and 2c in 1a and coupling section 2b,In these volt/bolt holes 1b and 2c compressed spring 4 the Inlaying equipment is done in the neck,It is interposing shoulder bolt 3, it fastens with nut 5 when alsoIn opening of volt/bolt hole 2c of coupling section 2b side, volt/bolt 32 surface widths 2e which obstruct the revolution of head 3a and nut 5,Being something which formed crevice 2f and 2h which possess 2g, the nutIn operation of compressed spring 4 after the fastening volt/bolt head 3a and nut5 with 2 surface widths 2e of crevice 2f and 2h and 2g revolution obstructionBecause of the re ru, while using there are no times when it loosens.
