Abstract
A vibratory sheepsfoot is attached to a coupling assembly that is mounted on a hydraulically operated tool bar on the back of a tractor. The coupling assembly is designed to permit adjustability of the vibratory sheepsfoot in a vertical direction. The coupling assembly is mounted on the tool bar such that it can be moved along the length of the tool bar to a desired position. The apparatus is especially useful in compacting earth in a trench offset to the side of the tractor.
Claims13
A primemover mountable device for compacting dirt in an area located at the side of and parallel to the direction of movement of said prime mover or in line therewith comprising:
- a. a tool bar mountable on one end of a primemover perpendicular to the direction of travel of said mover,
- b. a guide rail coextensive in length to said tool bar, the length of said rail being rigidly secured thereto along the length thereof,
- c. extending means, movably mounted on said guide rail and laterally extendable along said guide rail,
- d. a coupling means movably mounted on said extending means and having a vertical bore therethrough for movement of a mast therein,
- e. a mast disposed in said bore of said assembly, and vertically movable therein, and
- f. a vibratory earth compacting device mounted on the lower end of said mast wherein vertical movement of the mast brings said device into operative position for compacting dirt in the area along side of said primemover.
Apparatus for compacting earth comprising:
- a. a tractor, said tractor having a hydraulically operated tool bar mounted on its rear end,
- b. a guide rail rigidly secured to the tool bar, along the length thereof,
- c. a box bar laterally movable thereon, mounted on the guide rail, and
- d. a coupling assembly movably secured to the box bar,
- e. a mast mounted for vertical movement in the coupling assembly, and
- f. a vibratory sheepsfoot attached to the bottom of the mast, and
- g. a motor mounted on said coupling assembly for vertically moving said mast.
