Abstract
A vibratory compactor mounts onto the loader arms of a skid steer, and includes a freely turning packing wheel that is vibrated at a desired frequency and intensity. The vibrator and the packing wheel are mounted onto a subframe which in turn is mounted through isolation mounts back to a main frame that attaches to a skid steer loader so that the vibrations generated are not transferred at substantial levels back to the skid steer loader. The compactor includes a blade member that will move loose dirt into a trench that is being compacted by the packing wheel. The mounting for the packing wheel also can be adjusted to tilt the plane of the wheel, and the wheel can be moved laterally as well, to position the packing wheel close to fences or walls.
Claims20
A vibratory compactor for narrow trenches for use in combination with a skid steer loader having a hydraulically operated loader arm and a forward attachment plate supported on the loader arm, the attachment plate extending laterally of the skid steer loader and having a laterally extending guide rail supported thereon and extending across the attachment plate, the vibratory compactor having a first frame mounted on the guide rail of the forward attachment plate and being, positionable along the guide rail;
- a packing wheel adapted for rolling movement in a trench;
- a subframe, said subframe rotatably mounting said packing wheel for free rotation during compaction;
- a vibrator for vibrating said subframe and packing wheel at a desired intensity as the packing wheel toils in a trench;
- and vibration isolation means mounting said subframe relative to said first frame to isolate vibrations of the vibrator from being transferred back to the attachment plate.
A vibratory compactor for narrow trenches for use in combination with a mobile loader having a hydraulically operated loader arm, the vibratory compactor comprising:
- a main frame for mounting to the loader arm;
- a packing wheel adapted for rotatable movement in a trench;
- a subframe rotatably mounting said wheel;
- a vibrator attached to the subframe for vibrating said subframe as the packing wheel engages soil to be compacted;
- the main frame having a pair of spaced part side plates, and the subframe having a pair of side plates for supporting the packing wheel, the subframe side plates being positioned between the main frame side plates;
- and
- a plurality of elastomeric isolators having first ends attached to the main frame side plates and second ends attached to the subframe side plates to mount the subframe to the main frame and to isolate vibrations from the vibrator from being transferred back to the main frame.
A vibratory compactor for narrow trenches for use in combination with a prime mover, the vibratory compactor comprising:
- a first frame;
- a packing wheel mounted to the first frame for rotational movement and for movement in a trench;
- a vibrator for vibrating said packing wheel as the packing wheel rolls;
- and
- a support assembly between the prime mover and the first frame including members adjustable to permit a center plane of rotation of the packing wheel to be inclined relative to a generally vertical plane.
