Abstract

A discharge system with dual doors and an intermediate auger for dispensing materials from a storage receptacle either beneath the receptacle or remotely. The operator may select to discharge stored materials beneath the receptacle by opening an upper door and lower door to permit gravitational discharge from the receptacle. An intermediate auger is remotely coupled to an auger system for remote discharge. The auger system comprises two discrete sections selectively coupled by a pivot assembly. During coupling, the second section arcuately moves from a stowed position into a discharge position wherein receptive contact is established with the first section. The first section comprises an elongated conveyor disposed between the upper and lower doors to receive dispensed materials for subsequent output adjacent the trailer periphery. The conveyor comprises a cylindrical housing supporting a terminal hydraulic motor that rotates an internal screw auger to propel dispensed particulate material inside the transporter to an output orifice for transfer into the second section for external delivery. The second section comprises an auger transporter that comprises a cylindrical housing supporting a terminal motor rotating an internal screw auger that propels materials therethrough to an external discharge spout. The pivot assembly comprises a reinforcing sleeve that circumscribes an intermediate portion of the auger transporter to secure a hydraulic cylinder and a hinge thereto. The cylinder and hinge are oppositely anchored to the frame in proximity. The hinge comprises a sleeve circumscribing collar defining an integral base that is journalled between an upper trunnion and a lower trunnion by a roll pin. The sleeve comprises a rigid cylinder that concentrically extends along a portion of the auger transporter and is secured thereto.

Claims

1. A system for discharging particulate material from a storage bin, said system comprising:

an upper door forming a portion of the bottom of said bin, said upper door being adapted to move to an open position to dispense said particulate material;

a lower door adapted to selectively discharge said dispensed particulate material exteriorly of said bin and directly beneath said bin;

an integral chute extending between said upper door and said lower door to establish fluid flow communication, said chute channeling said dispensed particulate material downwardly from said upper door;

an intermediate auger disposed across said chute, said intermediate auger adapted to selectively move said dispensed particulate material to a terminus for subsequent discharge exteriorly of said bin and at the periphery of said bin; and

,

a pivotable elongated auger transporter with spaced apart ends having a hinge element for pivotally mounting said elongated auger transporter in proximity to said intermediate auger, said hinge element including;

a sleeve engaging a portion of said auger transporter between said spaced apart ends;

a pivot element associated with said sleeve and pivotally securing said sleeve with respect to said storage receptacle; and

,

an actuator for pivoting said sleeve about said pivot element to move said pivotable elongated auger transporter between a generally horizontal stowed position and a partially upright deployed position with one of said spaced apart ends in proximity to said intermediate auger terminus to receive dispensed particulate material from said intermediate auger and subsequently transport the dispensed particulate material away from said bin periphery for subsequent discharge.

2. The system as recited in claim 1 wherein said auger transporter is adapted to be disposed in either a stowed substantially horizontal position adjacent said receptacle or deployed in a partially upright position wherein one of said auger transporter ends is proximate said terminal portion.

3. The system as recited in claim 1 further comprising control means for permitting selective discharge of said dispensed material through said lower door or said intermediate auger or said auger transporter.

4. The system as recited in claim 3 wherein said auger transporter is adapted to be disposed in either a stowed substantially horizontal position adjacent said receptacle or deployed in a partially upright position and one of said auger transporter ends is proximate said terminal portion.
