Claim 10

A grain drier for drying grain, the drier comprising: an elongated drier housing; a wheeled vehicle frame for mounting said drier housing thereon; a first elongated horizontal cylindrical chamber formed in said housing, said first chamber having a first end portion and a second end portion; a second elongated horizontal cylindrical chamber formed in said housing, said second chamber having a first end portion and a second end portion, said second chamber adjacently disposed below and parallel to said first chamber, the first end portion of said second chamber communicating through an opening with the second end portion of said first chamber; a first auger having a hollow shaft with perforations therein, said first auger horizontally mounted in said first chamber; a second auger having a hollow shaft with perforations therein, said second auger horizontally mounted in said second chamber; a drive gear rotatably mounted on one end of said first auger, said drive gear meshing with a driven gear rotatably mounted on one end of said second auger, said gears driven by a drive shaft attached to said housing; a blower mounted on said drier housing, said blower communicating with the hollow shaft of said augers; a grain hopper mounted on said housing and disposed above the first end portion of said first chamber for feeding grain to be dried into said first chamber; and a transfer tube attached to said housing and communicating with the second end portion of said second chamber for receiving the dried grain conveyed therefrom, said transfer tube having a transfer tube auger mounted therein for conveying the dried grain through said transfer tube; the grain to be dried received at the first end portion of said first chamber from said grain hopper and conveyed by said first auger to the second end portion of said first chamber, said first auger feeding the grain from the second end portion of said first chamber into the first end portion of said second chamber, said second auger feeding the grain from the first end portion of said second chamber to the second end portion of said second chamber and discharging the grain into said transfer tube.

Claim 11

A grain drier for drying grain, the drier comprising: an elongated drier housing; a wheeled vehicle frame for mounting said drier housing thereon; a first elongated horizontal cylindrical chamber formed in said housing, said first chamber having a first end portion and a second end portion; a second elongated horizontal cylindrical chamber formed in said housing, said second chamber having a first end portion and a second end portion, said second chamber adjacently disposed below and parallel to said first chamber, the first end portion of said second chamber communicating through an opening with the second end portion of said first chamber; a first auger having a hollow shaft with perforations therein, said first auger horizontally mounted in said first chamber; a second auger having a hollow shaft with perforations therein, said second auger horizontally mounted in said second chamber; a drive gear rotatably mounted on one end of said first auger, said drive gear meshing with a driven gear rotatably mounted on one end of said second auger, said gears driven by a drive shaft attached to said housing; a blower mounted on said drier housing, said blower communicating with the hollow shaft of said augers; a grain hopper mounted on said housing and disposed above the first end portion of said first chamber for feeding grain to be dried into said first chamber; and a transfer tube attached to said housing and communicating with the second end portion of said second chamber for receiving the dried grain conveyed therefrom, said transfer tube having a transfer tube auger mounted therein for conveying the dried grain through said transfer tube; the grain to be dried received at the first end portion of said first chamber from said grain hopper and conveyed by said first auger to the second end portion of said first chamber, said first auger feeding the grain from the second end portion of said first chamber into the first end portion of said second chamber, said second auger feeding the grain from the first end portion of said second chamber to the second end portion of said second chamber and discharging the grain into said transfer tube.

Claim 12
