Abstract

The invention is a rake attachment for use with an excavator arm of heavy machinery. The preferred embodiment has two cross-members that make the invention easily installed with an automated excavator arm. An alternative embodiment provides for mounting hardware for use with a traditional excavator arm, which does not have a hydraulically operated attaching device. The invention is suited for use with the clearing of loose debris in and around a typical construction site. The construction debris may comprise loose wood scraps, tree branches, fencing, and other objects typical of a construction site.

Claims

1. A heavy equipment rake attachment for an excavator arm comprising:

(a) a rake including a plurality of raking prongs extending therefrom;

(b) a pair of longitudinally displaced mounting bars defining a mounting plane;

wherein the mounting bars are attached to the rake by a support structure, said rake being substantially centrally braced to extend laterally outward from said mounting bars, said rake being thereby maintained in braced manner relative to the excavator arm to brace against transverse recoil and direct said raking prongs transversely downward relative to the mounting plane for substantially upright raking engagement along a work surface;

wherein the mounting bars enable the rake to be attached to an automated attaching means of an excavator arm of a heavy equipment;

the automated attaching means including a hydraulically operated excavator attachment device having control arms actuable to releasably engage the mounting bars.

2. The heavy equipment rake attachment as described in claim 1 wherein the attaching means comprises welding, casting, or molding.

3. The heavy equipment rake attachment as described in claim 2 wherein the rake and the pair of mounting bars are made of a material comprising a metal.

4. A heavy equipment rake attachment for an excavator arm comprising:

(a) a rake including a plurality of raking prongs extending therefrom;

(b) a mounting plate defining a mounting plane and a pair of longitudinally displaced mounting members coupled thereto;

wherein the mounting plate is fastened to the rake by a support structure, said rake being substantially centrally braced to extend laterally outward from said mounting members, said rake being thereby maintained in braced manner relative to the excavator arm to brace against transverse recoil and direct said raking prongs transversely downward relative to the mounting plane for substantially upright raking engagement along a work surface; and

,

(c) a pair of mounting brackets formed to extend from the mounting plate for releasable attachment to an end of an excavator arm via an attaching means.

5. The heavy equipment rake attachment as described in claim 4 wherein the attaching means comprises a plurality of pins and pin clips coupling the end of the excavator arm to the mounting brackets in releasably locked manner.

6. The heavy equipment rake attachment as described in claim 5 wherein the rake, the mounting plate, and the mounting brackets are made of a material comprising a metal.

7. A heavy equipment rake attachment for modular coupling to an excavator arm for ground working manipulation thereby, comprising:

a mounting portion extended along a mounting plane, said mounting portion including a pair of longitudinally displaced mounting members;

a rake including a plurality of raking prongs extending therefrom, said raking prongs being disposed in spaced manner along at least one raking plane; and

,

a support structure offsetting said rake from said mounting portion, said support structure including a plurality of support members projecting forward and downward to said rake from said mounting portion, said rake being substantially centrally braced to extend laterally outward from said mounting members, said rake being thereby maintained in braced manner relative to the excavator arm to brace against transverse recoil and direct said raking prongs transversely downward relative to the mounting plane for substantially upright raking plane engagement along a ground surface.

8. The heavy equipment rake attachment as recited in claim 7, wherein said rake includes a laterally extended stabilizer bar, said raking prongs being spaced laterally along said stabilizer bar to project transversely downward therefrom.

9. The heavy equipment rake attachment as recited in claim 7, wherein said raking prongs are varied in relative spacing along said raking plane.

10. The heavy equipment rake attachment as recited in claim 7, wherein a front pair of said support members terminate respectively at a pair of spaced prongs defining a second raking plane offset from said raking plane defined by said raking prongs.

11. The heavy equipment rake attachment as recited in claim 7, wherein said mounting members are spaced one from the other along said mounting plane.

12. The heavy equipment rake attachment as recited in claim 7, wherein said mounting portion includes:

a mounting plate extending along said mounting plane and a pair of mounting brackets formed thereon for receiving a coupling end of the excavator arm therebetween; and

,

a plurality of pins releasably coupled to said mounting brackets for locking the coupling end of the excavator arm thereto.

13. The heavy equipment rake attachment as recited in claim 12, wherein said mounting portion further includes a plurality of releasable pin clips retaining said pins on said mounting brackets.

14. The heavy equipment rake attachment as recited in claim 7, wherein said support structure is joined to each of said mounting portion and said rake by a welding, casting, or molding.

15. The heavy equipment rake attachment as recited in claim 7, wherein said rake and said mounting portion are each made of a metallic material.
