Definitions

  • the present invention relates to a vibrating nipper for heavy equipment, mounted on heavy equipment such as excavators, bulldozers, and wheel loaders, capable of effectively crushing and excavating in the fields of civil engineering and demolishing, and more particularly, to a vibrating nipper with improved durability including a vibrating body in which a plurality of gears having eccentric pendulums are longitudinally arranged and rotated and generate longitudinal vibration in such a way that the width of the vibrating body may be manufactured to be narrow to deeply insert a nipper blade into the ground, a frame is connected to the vibrating body in a link structure to freely operate the nipper blade, and built-in buffers are protected.
  • a breaker formed of an iron pin is mounted on an arm of heavy equipment and strikes the bedrock to be crushed.
  • FIGS. 1 and 2 illustrate a general vibrating nipper 1 .
  • the vibrating nipper 1 has a configuration in which a vibrating body 20 is arranged inside a guide bracket 10 on whose top a mount part 12 is formed, the vibrating inside which a vibrator with two axes is formed including a configuration in which a gear 23 of a driving axis 22 on which an eccentric weight 21 operated by an oil hydrolytic motor (not shown) is installed is laterally interlocked with a gear 23 ′ of a driven axis 22 ′ on which an eccentric weight 21 ′ is installed.
  • both outsides of the vibrating body 20 are coupled with each other using dustproof rubbers 31 , 31 ′, 32 , and 32 ′ and guide bearings 41 and 42 are installed on top and bottom between the inside of the guide bracket 10 and the outside of the vibrating body 20 , where the dustproof rubbers 31 , 31 ′, 32 , and 32 ′ mounted on, in such a way that outer circumferential surfaces of the guide bearings 41 and 42 are separated from an outer surface of the vibrating body 20 with a certain interval.
  • a nipper blade 50 is installed on a bottom of the vibrating body 20 by using an interlocking bolt.
  • the gears 23 and 23 ′ rotated by the oil hydrolytic motor inside the vibrating body 20 are laterally interlocked and horizontally arranged in such a way that a width W of the vibrating body 20 becomes relatively wider, which prevents the vibrating body 20 with such wide width W from being inserted into the ground though the nipper blade 50 is inserted into the ground. Accordingly, such configuration in which the gears 23 and 23 ′ are laterally arranged inside the vibrating body 20 has a problem while deeply excavating the ground.
  • the vibrating nipper 1 receives excavation-resistance of from the ground in a direction opposite to that of the move of the nipper blade 50 , that is, in a direction of A in FIG. 1 .
  • the vibrating nipper 1 may be easily damaged and durability thereof is decreased to spend a lot of time to mend or maintain the same.
  • an aspect of the present invention provides a vibrating nipper for heavy equipment, the vibrating nipper having a configuration in which built-in gears and eccentric pendulums longitudinally vibrate due to reaction force of an oil hydrolytic motor regardless of a vibrating body manufactured to have a narrower width and the vibrating body is capable of being deeply inserted into the ground along a nipper blade when excavating the ground, thereby improving excavation performance.
  • An aspect of the present invention also provides a vibrating nipper for heavy equipment, the vibrating nipper having a configuration in which, when a nipper blade receives lateral resistance force from the ground while excavating the ground, since the nipper blade and a vibrating body are connected to each other to form a longitudinally displaceable link structure, the lateral resistance force to the nipper blade is greatly buffered to allow the nipper blade to freely operate and buffers supporting the vibrating body are protected, thereby greatly improving durability thereof.
  • a vibrating nipper mounted on an arm of heavy equipment such as an excavator, a bulldozer, and a wheel loader to simultaneously crush and excavate in the field of civil engineering and demolishing
  • the vibrating nipper including a vibrating body in which gears rotated by an oil hydrolytic motor are longitudinally arranged to be rotatable, an eccentric pendulum mounted on each of the gears to generate 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.
  • the vibrating body may have a configuration in which the three gears are longitudinally arranged and the size of a rotation moment of an eccentric pendulum of a central gear is a double of the size of rotation moments of eccentric pendulums connected to top and bottom gears in such a way that, when rotating the gears, later centrifugal forces generated from the eccentric pendulums of the top and bottom gears have the same size in a different direction as that of the eccentric pendulum of the central gear to mutually compensate one another and mutual centrifugal forces thereof are overlapped, thereby generating vibration.
  • the top gear is connected to the oil hydrolytic motor and operates as a driving gear, the central gear rotates in a direction opposite to that of the top gear, and the bottom gear rotates in a direction opposite to that of the central gear. Accordingly, when the eccentric pendulums of the top and bottom gears are laterally located, the eccentric pendulum of the central gear is laterally arranged opposite thereto, thereby compensating mutual centrifugal forces. When the eccentric pendulums of the top and bottom gears are longitudinally located, the eccentric pendulum of the central gear is longitudinally arranged in the same direction as that of the eccentric pendulums of the top and bottom gears, thereby overlapping centrifugal forces and generating longitudinal vibration.
  • the vibrating body may have a configuration in which front top and bottom corners thereof are connected to a frame surrounding the vibrating body using links and pins in the shape of a double lever link device and to allow levers of top and bottom links to trace arcs and to allow top and bottom displacement to be possible.
  • a front corner and a rear corner of the vibrating body are supported by a plurality of buffers built in the frame, respectively.
  • the buffers are formed of dustproof rubbers mounted on both side plates formed of iron, respectively to buffer vibration.
  • a vibrating nipper having a configuration in which a vibrating body is manufactured to have the width relatively narrower than general ones by longitudinally arranging gears inside the vibrating body, on each of which an eccentric pendulum is mounted to generate longitudinal vibration while rotating the gears. Accordingly, it is possible to form a frame with a narrow breadth simultaneously with a structure strong enough not to be an obstacle while excavating, thereby deeply inserting a nipper blade into the ground to increase the depth of excavation and greatly improving excavation performance.
  • front top and bottom corners of the vibrating body are connected to the frame surrounding the vibrating body by using links and pins to longitudinally trace arcs and to be displaceable, though the nipper blade receives lateral excavation-resistance force from the ground while excavating the ground, it is possible to sufficiently support the lateral excavation-resistance force to the nipper blade to strongly excavate the ground and the nipper blade freely perform longitudinal operation to protect buffers supporting the vibrating body not to be damaged, and durability thereof is greatly improved due to a longitudinally displaceable link structure of connecting the nipper blade and the vibrating body to the frame.
