<p>A device (10) for unloading particulate material from circular storage bins (11) having central discharge sumps (13). The device (10) includes two augers (18, 20) extending radially in diametric opposition from a vertical pivot axis adjacent the discharge sump (13). The augers (18,20) are powered to pivot forwardly about the vertical axis and are also rotated about longitudinal auger axes to engage and move particulate material toward the vertical axis and into the central outlet sump. A central counter rotating auger drive means (16) is powered to rotate the augers in opposite directions. The counter rotating drive means (16) includes a single input drive shaft (30). The single input shaft (30) rotates two worm gears (31,35) of a transmission means. Two worm wheels, (32,36) each attached to a respective auger, mesh with the worm gears (31,35). The worm gears (31,35) and worm wheels (32,36) function as gear reduction units to transmit rotation of the input shaft (30) to opposite geared down directional rotation of the augers. The single input drive shaft (30) is also operatively connected to a hydraulic pump (37). Fluid under pressure from the hydraulic pump (37) is delivered to outbound drive wheel assemblies which, in turn, pivot the auger units forwardly about the vertical axis. Splash guards (48) are mounted to the auger assemblies, facing forwardly to engage and direct material downwardly toward the augers.</p> |
