Constant down force vibratory compactor
First Claim
1. A vibratory compactor, comprising:
- a support frame defining an interior space and including a base disposed at a lower end thereof configured to contact a work surface;
a guide member attached to the support frame;
a vibratory mechanism including a vibratory housing including;
a contact plate disposed on the vibratory housing, the contact plate configured to compact the work surface;
one or more excitation devices configured to vibrate the contact plate;
a guide opening formed through the vibratory housing, the guide opening configured to movably receive the guide member and configured to permit the vibratory mechanism vertical movement relative to the support frame; and
at least one biasing member disposed between the support frame and the vibratory housing, the at least one biasing member generating a selected force between the support frame and the vibratory housing when the base of the support frame is in contact with the work surface.

Abstract
A vibratory compactor for a work machine, includes a support frame that defines an interior space and includes a base disposed at a lower end thereof configured to contact a work surface. A guide member is attached to the support frame. A vibratory mechanism includes a vibratory housing and includes a contact plate. The contact plate is configured to compact the work surface. An excitation device is configured to vibrate the contact plate. A guide opening is formed through the vibratory housing configured to movably receive the guide member and to permit the vibratory mechanism vertical movement relative to the support frame. At least one biasing member is disposed between the support frame and the vibratory housing and generates a selected force between the support frame and the vibratory housing when the base is in contact with the work surface.

17. A method of operating a vibratory compactor, comprising:
-
contacting, with a vibratory mechanism of the vibratory compactor, a work surface; contacting, with a support frame of the vibratory compactor, the work surface; generating, with a biasing member, a selected down force between the support frame and the vibratory housing; and generating a fluctuating vertical force with the vibratory mechanism that in combination with the selected down force, causes compaction of the work surface. - View Dependent Claims (18, 19, 20)
