The manure rake or barn stall rake apparatus of the invention includes a shaker assembly that both vibrates and shakes the manure basket of the rake to expeditiously separate the manure from the bedding.
Claims21
A manure rake apparatus, said apparatus comprising:
- a waste receptacle having a forward facing edge defining an opening into the receptacle;
- a handle including a sheath having a hollow interior and drive shaft extending through the hollow interior of the sheath, wherein a first end of the handle is fixed to the receptacle and a second end of the handle is fixed to a first hand grip;
- a second hand grip fixed to the sheath of the handle between the first end of the handle and the second end of the handle;
- a rotary motor coupled to a first end portion of the drive shaft;
- a shaker assembly including a housing, waste receptacle end cap, handle end cap, and an eccentric weight, wherein the drive shaft extends through the handle end cap, housing and waste receptacle end cap and further wherein the drive shaft includes a coupler that couples the shaft to an aperture extending through the eccentric weight;
- and
- wherein the aperture of the eccentric weight extends through the eccentric weight such that a central axis of the aperture is not perpendicular to the rotational plane of the weight.
