Abstract
An open top box having a chamber for carrying particulate materials. An open grid covers the top of the box. A tongue and wheel assembly is removably connected to the base frame of the box. A plurality of augers removably located in the chamber rotate to mix and blend the materials in the chamber. Power transmitting structure mounted on the back of the box operates to rotate the augers. A material discharge conveyor attached to the side of the box operates to laterally discharge the mixed materials to a desired location.

An apparatus for mixing particulate materials comprising:
- box means having upright front and rear end walls and and side walls surrounding a chamber for accommodating particulate materials, one of said side walls having a discharge opening located between the ends of the one side wall, said box means having an open top whereby the particulate materials can be placed in the chamber, auger means mounted on the box means and located in the chamber to mix the particulate materials in the chamber, said auger means including first and second lower augers and third and fourth upper augers extended between front and rear end walls, said first and second augers being located in the bottom section of the chamber and said third and fourth augers being located above the first and second augers and positioned generally parallel to the first and second augers, each of said first, second, third and fourth augers having two spiral flights with opposite spiral patterns, said first auger having a first spiral flight operable to move material from the front end wall toward the discharge opening and a second spiral flight operable to move material from the rear end wall to the discharge opening, said second auger having a first spiral flight and a second spiral flight operable to move material from the midsection of the chamber toward the front and rear end walls, said third and fourth augers each having first and second spiral flights, one of said third and fourth augers being operable to move material from the front and rear walls toward the midsection of the chamber, the other of said third and fourth augers being operable to move material from the midsection to the front and rear end walls, drive means for rotating the first and second augers in opposite directions and for rotating the third and fourth augers in opposite directions, open means mounted on the box means and located over the entire open top of the box means to prevent large objects from entering the chamber and allowing particulate materials to be placed in the chamber, and door means for selectively opening and closing the discharge opening whereby particulate materials are discharged from the chamber when the door means is open.
An apparatus for mixing particulate materials comprising:
- box means having a chamber for accommodating particulate materials, means mounted on the box means and located in the chamber for mixing the particulate materials in the chamber, means for selectively discharging particulate materials from the chamber, said box means having a side wall with a discharge opening, an upright first end wall and an upright second end wall, said means for mixing the particulate material including auger means extended between said end walls, said auger means including first and second lower augers located in the bottom section of the chamber and third and fourth upper augers located above and positioned generally parallel to the first and second augers, each of said first, second, third and fourth augers having two spiral flights with opposite spiral patterns, said first auger having a first spiral flight operable to move material from the first end wall toward the discharge opening and a second spiral flight operable to move material from the second end wall toward the discharge opening, said second auger having a first spiral flight and a second spiral flight operable to move material from the midsection of the chamber toward the first and second end walls, said third and fourth augers each having first and second spiral flights, one of said first and second spiral flights of the third and fourth augers operable to move material from the opposite end walls toward the midsection of the chamber, the other of said first and second flights of the third and fourth augers operable to move material from the midsection toward the first and second end walls, and connector means releasably attached to the ends of said augers for mounting the augers on said end walls whereby the augers can be removed from the apparatus, and drive means operably connected to the connector means on one end wall for rotating the first and second augers in opposite directions and the third and fourth augers in opposite directions thereby mixing the particulate materials in the chamber.
An apparatus for mixing particulate materials comprising:
- box means having front and rear end walls and a side wall including a material discharge opening, said walls defining a chamber for accommodating particulate materials, auger means mounted on the end walls and located in the chamber to mix the particulate materials in the chamber, means for selectively discharging particulate materials from the chamber, said auger means including first and second lower augers positioned in the lower portion of said chamber and third and fourth augers located above the first and second augers and positioned generally parallel to the first and second augers, each of said first, second third and fourth augers having two spiral flights having opposite spiral patterns, said first auger having a first spiral flight operable to move material from one end wall toward the discharge opening and a second spiral flight operable to move material from the other end wall to the discharge opening, said second auger having a first spiral flight and a second spiral flight operable to move material from the midsection of the chamber toward the front and rear end walls, said third and fourth augers each having first and second spiral flights, one of said first and second spiral flights of the third and fourth augers operable to move material from the end walls toward the midsection of the chamber, the other of said first and second spiral flights of the third and fourth augers operable to move material from the midsection to the front and rear end walls, drive means for rotating the first and second augers in opposite directions and for rotating the third and fourth augers in opposite directions, said box means having a base frame, tongue means releasably secured to the base frame and extended forwardly of the box means, a transport wheel and axle assembly for supporting the box means on the surface, said assembly having support members releasably mounted on the base frame, and releasable fastener means connecting the support members to the box frame whereby the wheel and axle assembly can be removed from the base frame.
An apparatus for mixing particulate materials comprising:
- box means having end walls and a chamber for accommodating particulate materials, means mounted on the box means and located in the chamber to mix the particulate materials in the chamber, means for selectively discharging particulate material from the chamber, said means to mix the particulate materials including a pair of upper augers and a pair of lower augers, said lower augers each having a first spiral flight and a second spiral flight, said second spiral flight having a reverse twist from the first spiral flight, said first spiral flight of one of the lower augers being longitudinally longer than the second spiral flight of the other lower auger, said upper augers comprising a first auger having first and second spiral flights operable to move material from the midsection of the chamber toward the end walls, and a second auger having first and second spiral flights operable to move material from the end walls toward the midsection of the chamber, and drive means operable to rotate the lower augers in opposite directions and to rotate the upper augers in opposite directions.
