Vibration nipper for heavy machinery

Abstract

There is provided a vibrating nipper including a vibrating body in which a plurality of gears built therein and having eccentric pendulums are longitudinally arranged and rotated to generate longitudinal vibration, the vibrating body in which the gears rotated by an oil hydrolytic motor are longitudinally arranged to be rotatable, an eccentric pendulum mounted on each of the gears to generate the longitudinal vibration while rotating the gears, wherein a nipper blade is longitudinally mounted on a bottom of the vibrating body in such a way that the vibrating body is capable of being inserted deeply into the ground along the nipper blade when excavating the ground.

1 - 3 . (canceled) 
     
     
         4 . A vibrating nipper mountable on an arm of heavy equipment, the vibrating nipper comprising:
 a vibrating body comprising a plurality of gears rotated by an oil hydrolytic motor, wherein the plurality of gears are longitudinally arranged to be rotatable,   an eccentric pendulum mounted on each of the plurality of gears to generate longitudinal vibration while rotating the gears, and   a nipper blade which is longitudinally mounted on a bottom of the vibrating body in such a way that the vibrating body is capable of being inserted into ground along the nipper blade.   
     
     
         5 . The vibrating nipper of  claim 4 , wherein the vibrating body comprises three gears. 
     
     
         6 . The vibrating nipper of  claim 5 , wherein the vibrating body has a configuration in which the size of a rotation moment of an eccentric pendulum of a central gear is an half of the size of a rotation moment of eccentric pendulums connected to top and bottom gears in such a way that, when rotating the gears, later centrifugal force generated from the eccentric pendulums of the top and bottom gears has the same size in a different direction as that of the eccentric pendulum of the central gear to mutually compensating one another and mutual centrifugal forces thereof are overlapped, thereby generating vibration. 
     
     
         7 . The vibrating nipper of  claim 4 , wherein the vibrating body has a configuration in which top and bottom corners of the vibrating body are connected to a frame surrounding the vibrating body via links and pins in the shape of a double lever link device. 
     
     
         8 . The vibrating nipper of  claim 7 , wherein the configuration allows levers of top and bottom links to trace arcs and to allow top and bottom displacement to be possible. 
     
     
         9 . The vibrating nipper of  claim 4 , wherein the heavy equipment is an excavator, a bulldozer, or a wheel loader.
