BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is for a baler, and more particularly, pertains to a baler with interlocking tab and slot fabrication in the main baler body and in the vertically positionable sliding bale door which is utilized in the fabrication process.

2. Description of the Prior Art

While prior art balers performed the function of baling waste, problems were encountered subsequent to lengthy or abusive use of the baling device, such as attempting to compress an excessive amount of material into a volumetric area of questionable strength which caused warpage and distortion of the geometry of a baler's physical geometric alignment. Such misalignment, of course, manifested itself in jamming of the ram, or breakage of the ram components or of enclosure components. Clearly, what is needed is a baler constructed to stand up to the rigors of lengthy use or even various baler abuses which will not distort the geometric alignment.

The present invention provides such a baler of heavy wall reinforced construction featuring interlocking tab and slot construction which is self-aligning and self-locating during the fabrication process with additional interlocking vertical and cross stringer reinforcement to obtain maximum structural integrity.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 illustrates an isometric view of a baler 10, the present invention, where the major illustrated components include a mechanical chamber 12 aligned contiguously with a charge or gather chamber 14, a bale chamber 16, a vertically positionable bale chamber door 18, a hydraulic power unit 20, an electrical control panel 22 mounted to the hydraulic power unit 20, a ram cover 24 secured to one end of the mechanical chamber 12, and a gather chamber cover 26 aligned to the top of the mechanical chamber 12.

Structural integrity and alignment of the baler 10 is maintained by the use of heavy gauge steel plate, and the incorporation of interlocking devices and reinforcing members which are welded or otherwise secured throughout and within to bind and reinforce large planar plate members. In addition, the interlocking tabs and corresponding slots are cut precisely. The precise cutting is also a very important part of the fabrication process in that alignment jigs and other external support devices are not required because the tabs and slots are so precisely cut that their close fitting relationship causes the component members to be self-aligning and to locate without external jig or other support. Thus, a great deal of time and effort are saved during fabrication. With reference to FIG. 1 and/or FIG. 2, the main structure is now described in detail. A variety of components center about and build upon a horizontally aligned and configured essentially rectangular-shaped base plate 28 of FIG. 2. The planar base plate 28 includes opposing edges 30 and 32 having a plurality of tabs, including tabs 34, 36, 38 and 40, some of which are notched, projecting from edge 30, and corresponding tabs 42, 44, 46 and 48, some of which are notched, projecting from edge 32. A larger U-shaped cutout 50 is located at one end of the base plate 28. A plurality of slots 52a-52f are located at the opposing end of the base plate 28 to accommodate wire ties.
