Definitions

  • the present invention relates to a bucket device for a rocker shovel and more particularly to an apparatus for backward swinging of the bucket of the loader.
  • the present invention intends to eliminate the abovementioned shortcomings of the conventional rocker shovel.
  • the apparatus is characterized in that the bucket is operated by a single unit of cylinder means and linkage means; the bucket is moved to and upper position and thereafter the bucket is reversed automatically by the weight of .the bucket and'its contents to discharge the contents.
  • FIG. 1 is a plan view of an embodiment of the bucket device according to the present invention.
  • FIG. 2 is a side elevation thereof
  • FIG. 3 is a side elevation before reversing the bucket
  • FIG. 4 is a side elevation when reversing the bucket.
  • FIG. 5 is a side elevation of the bucket shown returning to the position shown in FIG. 2.
  • bucket 11 is pivoted to a link 13 by means of pin 12, the link 13 being jointed with the front end rising portion F of body frame F by means ofa pin 14.
  • Links 20 and 21 are connected by a pin 27 and the I respective end of both links are pivoted to the rising which is rotatably mounted, by means of pin 29, on the, body frame F.
  • Bucket 11 is rotatably joined at the upper end portion thereof, with link by means of pin 17 and the end of the link 15 is rotatably joined, by means of pin 18, with one end of link 16.
  • the link 16 is ,rotatably joined, by means of pin 19, with the upper end of the rising portion F of body frame F.
  • a triangular stopper 23 for regulating the rotation of link 16, so that the clockwise rotation of link 16 is stopped by engagement of the rear end portion thereof with the rear side of stopper 23 and the counter-clockwise rotation is stopped by engagement of the front end portion with the front slope of stopper 23.
  • Stopper 25 for limiting the reversing rotation of bucket 11 is provided at the top end portion of the link 13.
  • Numeral 24 indicates a conveyor hopper.
  • the bucket is moved up to the predetermined position by means of a cylinder, and the bucket is reversed by the weight of the bucket and thus power for reversing the bucket can be saved.
  • the cylinder for reversing the bucket used in conventional loader is not required, thereby manual operation for reversing the bucket is not needed and the bucket operation is remarkably simplified.
  • a bucket device for a rocker shovel comprising a body frame, a link member pivotally connected at one end thereof to said body frame for rotation about a horizontal axis, a bucket pivotally supported at the back bottom portion thereof by the other end of said link member.
  • a first stopper on said link member for restricting the backward pivotal dumping movement of said bucket with respect to said link member
  • a hydrau lic cylinder pivotally attached to said body frame and said link member for selectively rotating said link member, a first link pivotally connected at one end thereof to said bucket at a point above the connection of said bucket to said link member, a second link pivotally connected at one end thereof to the free end of said first link and at the other end thereof to said body 4 frame at a point spaced above the point of connection of said link member to said body frame.
