Abstract
A filler block for clean grain tanks of grain harvesters which prevents the trapping of grain and other materials in the grain tank. The filler block fills the dead spaces of the grain tank where grain and other materials may be trapped and presents a top surface which sheds grain and other materials to ensure that all such materials are conveyed out of the clean grain tank upon emptying. The filler blocks eliminate the need for manual cleaning and extend the life of the grain tank.
Claims4
A grain storage tank with at least one filler block, said combination comprising:
- a grain storage tank with a bottom wall section;
- a generally horizontal auger located above said bottom wall section for moving grain generally horizontally along said bottom wall section;
- a generally vertical auger interacting with said horizontal auger to move grain generally vertically out of said grain storage tank;
- a shroud covering at least a portion of said horizontal auger thereby forming a dead space that traps grain and other material from contact with said horizontal auger;
- and
- a filler block located above said shroud and over said dead space and shaped to divert grain and other material away from said dead space.

A grain storage tank with two filler blocks, said combination comprising:
- a grain storage tank with a first and second downward sloping bottom wall sections forming a generally U-shaped trough;
- a first and a second horizontal auger located side by side and above said generally U-shaped trough, said augers for moving grain horizontally along said bottom wall sections;
- a vertical auger interacting with said horizontal auger to move grain generally vertically out of said grain storage tank;
- a shroud covering at least a portion of said first and second horizontal augers at said area of interaction between said vertical and horizontal augers, thereby forming a dead space that traps grain and other material from contact with said horizontal augers;
- a first filler block located above said shroud and over said dead space, said first filler block having a first end surface forming to said first downward sloping bottom wall section, a second end surface forming to a first side of said vertical auger, a bottom surface forming to a portion of said shroud covering said first horizontal auger, and a top surface shaped to divert grain and other material away from said dead space;
- and
- a second filler block located over said dead space, said second filler block having a first end surface forming to said second downward sloping bottom wall section, a second end surface forming to a second side of said vertical auger opposite said first side of said vertical auger, a bottom surface forming to a portion of said shroud covering said second horizontal auger, and a top surface shaped to divert grain and other material away from said dead space.
