Abstract
A hydraulically operated vibratory soil compactor adapted for use with a loading boom such as a backhoe. Improved construction includes a rectangular structural steel tube welded to a vibrating base plate for providing: structural reinforcement; a sealed housing for an eccentric weight vibrator; and, a supporting surface for shear type springs or shock mounts. A hydraulic drive motor is also mounted on the outside of the central tube member. Improved construction further includes an I-beam section welded between a pair of inverted U-shaped plates to form a tunnel type mounting frame having four arms for connection to the shock mounts supported on the tube member.
Claims8
A vibrating plate compactor adapted for connection to and use with a loading boom comprising:
- a base plate for engaging a work surface,
- a rectangular structural steel tube having one of a first pair of opposite sides bonded to said base plate, and having opposing centrally positioned apertures in each of a second pair of opposite sides,
- bearing means carried in said apertures,
- a shaft supported by said bearing means including an eccentric weight positioned within said tube,
- a mounting frame comprising a pair of parallel inverted U-shaped plates having arms symmetrically spaced about the second pair of sides of said tube and equally spaced from said base plate, and
- spring means positioned between and attached to the arms of said U-shaped plates and opposing surfaces of said structural steel tube.
In a vibratory compactor of the type having a work engaging base plate, a rotating eccentric weight vibrator for vibrating said base plate, and a mounting frame coupled to said base plate by shear springs, the improvement comprising:
- a rectangular structural steel tube having one of a first pair of opposite sides bonded to the top surface of said base plate, said tube having opposing centrally positioned apertures in each of a second pair of opposite sides, and
- bearing means supported in said apertures for supporting said rotating eccentric weight within said tube,
- wherein one end of each of said shear springs is directly connected to the longer sides of said tube.
In a vibratory compactor of the type including a mounting frame adapted for connection to a loading boom, a base plate, a vibration generator attached to said base plate, and spring means coupling said base plate to said mounting frame, an improved mounting frame comprising:
- a pair of parallel inverted U-shaped side plates each having arm portions adapted for connection to said spring means and a bight portion adapted for connection to said boom, and a section of structural steel I-beam bonded between said side plates to hold said side plates in a preselected parallel spaced apart position, wherein the web of said I-beam is generally parallel to said base plate.
