Abstract
A kind of multi-functional electric pick of linear electric motors driving of the present invention is mainly used in building engineering field breaking concrete or concrete punching uses, and it be able to can also both be punched with breaking concrete, breaking concrete efficiency high, and maintenance of equipment is simple；It mainly includes shell, linear motor stator electric, linear motor rotor, central shaft, bearing, handrail, crushing rod；Its operation principle is:When linear motor rotor connects positive power supply, linear motor rotor does linear motion vertically upward, and drives crushing rod to do linear motion vertically upward, while drives crushing rod to rotate；When linear motor rotor turn-on reversal power supply, linear motor rotor does linear motion vertically downward, and crushing rod is driven to do linear motion vertically downward, crushing rod is driven to rotate backward simultaneously, mattess is crushed or punched under this linear motion repeatedly by the crushing head of crushing rod, the crushing head of crushing rod is positive simultaneously and rotates backward cutting hole wall, and crushing rod will not be stuck.
