A bin sweep auger unplugging system for unplugging a central unloading sump in a storage bin. The bin sweep auger unplugging system generally includes an auger having a driven shaft with auger fighting, a drive unit having a drive shaft, and a clutch connected between the drive shaft and the driven shaft. The clutch selectively transfers the rotation of the drive shaft to the driven shaft of the auger. The drive shaft includes a clump breakup component that breaks up the clump of granular material above the unloading sump when the drive shaft is rotated. The clutch is disengaged when breaking up a clump of granular material to prevent the rotation of the auger.

In a batch weighing/supply device for a raw material such as a granular material, a primary height adjustable scraper 17 that reduces the quantity of conveyed raw material when lowered is provided on an upstream side of a discharge port 6 in an annular passage 5, a secondary height adjustable scraper 19 that further reduces the quantity of conveyed raw material, after the quantity has been reduced by lowering the primary height adjustable scraper, is provided on a downstream side of the primary height adjustable scraper and directly adjacent to the discharge port on the upstream side thereof, control means 37 is provided to reduce the rotation speed of rotary blades 8 and 10 to a first speed, which is lower than a normal speed, when the primary height adjustable scraper is lowered and reduce the rotation speed of the rotary blades to a second speed, which is lower than the first speed, when the secondary height adjustable scraper is lowered, and a sliding gate 24 capable of opening and closing a raw material drop-down path is provided in a chute unit provided under the discharge port.

An apparatus and method for breaking up clumps of grain encountered during the emptying of a grain bin includes a beater assembly having a shaft with a plurality of knives extending radially therefrom. The beater assembly is adapted to be attached to or unattached from an end of a sweep auger. The beater assembly is positioned to overlay a gated opening in the floor of the grain bin through which grain flows during unloading thereof. The same motor used to drive the bin's discharge auger located below the bins floor also is made to drive the beater assembly located above the floor by linking the shaft of the discharge auger through a pair of right angle gear boxes to the shaft of the beater assembly.

A wet particle storage tank includes a tank body capable of storing wet particles containing particles and solvent. The tank body has an upper storage section having a supply port through which the wet particles are supplied, a lower storage section located below the upper storage section and having a discharge port through which the wet particles are discharged, and a bridge forming section provided between the upper storage section and the lower storage section. The bridge forming section facilitates formation of a bridge by the wet particles to block falling of the wet particles from the upper storage section to the lower storage section.
