Abstract
A solid waste displacement system, more specifically a system affixed to a mobile structure (such as, for instance, a truck bed, a trailer, and the like), provided. Such a system includes a drive shaft coupled to a movable wall assembly that provides sufficient force to push solid waste from the mobile structure along the drive shaft when operated. The drive shaft may be a chain driven device or any other like mechanism that accords movement and force to the movable wall assembly for such a solid waste displacement purpose. The device as well as the method of utilizing such a device on and/or within a mobile structure are encompassed herein.
Claims10
A solid waste displacement system, comprising:
- a power unit having a rotatable output shaft;
- a traveling waste displacement assembly movable along a displacement axis between a retracted position and an extended position;
- a drive shaft rotatably coupled to the power unit via a first coupling, the drive shaft supported for rotation about a longitudinal drive shaft axis, the drive shaft extending from the first coupling to a second coupling;
- at least one support base comprising a first set of bearing support members each comprising at least one orifice, the first set of bearing support members fixed and extending vertically relative to the at least one support base;
- a first set of sealed bearings threadably affixed to the first set of bearing support members of the at least one support base;
- a first shaft rotatably coupled to the drive shaft in driven relationship, the first shaft penetrating the at least one orifice of each of the first set of bearing support members;
- at least one first drive sprocket each comprising a first set of teeth, the at least one first drive sprocket coupled to the first shaft for rotation therewith, the at least one first drive sprocket positioned between at least two of the first set of bearing support members of the at least one support base;
- a second set of bearing support members supported in fixed relationship with the at least one support base, the second set of bearing support members spaced apart from the first set of bearing support members along the displacement axis, the second set of bearing support members each comprising at least one orifice;
- a second set of sealed bearings threadably affixed to the second set of bearing support members;
- a second shaft penetrating the at least one orifice of each of the second set of bearing support members;
- at least one second drive sprocket each comprising a second set of teeth, the at least one second drive sprocket coupled to the second shaft for rotation therewith, the at least one second drive sprocket positioned between at least two of the second set of bearing support members of the at least one support base;
- and a chain guide extending from the first set of bearing support members to the second set of bearing support members;
- said traveling waste displacement assembly comprising:
- a traveling guide configured to move along the chain guide between a retracted position and an extended position, the traveling guide translationally engageable with the chain guide;
- a wall carried at least in part by the traveling guide for translational movement therewith, the wall extending perpendicularly outward from the traveling guide and the chain guide;
- and a roller chain trained about the first set of teeth and the second set of teeth, the roller chain coupled to the traveling guide.
