Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
277 words
In a portable grain dryer which includes a wheel-supported frame adapted to be pulled from one location to another, a grain holding bin and a grain drying unit constituting parts of said frame, said drying unit having an inlet and an outlet, first conveyor means extending between said bin and said drying unit inlet for transporting grain from said bin to said drying unit, the improvement comprising second conveyor means carried by said frame, said second conveyor means constituting two conveyor units each having its own loading and discharge ends, one of said conveyor units having its loading end positioned in grain flow communication with said drying unit outlet and having its discharge end positioned in grain flow communication with the loading end of the other of said conveyor units wherein grain is received from said drying unit by said one conveyor unit and carried thereby to the other conveyor unit, means anchoring the loading end of said other conveyor unit to said frame for permitting universal pivotal movement of said other conveyor unit and the shifting of both ends thereof, means for moving said other conveyor unit so as to permit the discharge end of said other conveyor unit to be shifted into a selected location spaced from said dryer unit, means anchoring the loading end of said one conveyor unit to said frame for permitting pivotal movement of said one conveyor unit, means for moving the discharge end of said one conveyor unit into grain flow communication with the loading end of said other conveyor unit to accommodate movement of said other conveyor unit when said other conveyor unit is shifted into said selected location.

In a portable grain dryer which includes a wheel-supported frame adapted to be pulled from one location to another, a grain holding bin and a grain drying unit constituting parts of said frame, said drying unit having an inlet and an outlet, first conveyor means extending between said bin and said drying unit inlet for transporting grain from said bin to said drying unit, the improvement comprising second conveyor means carried by said frame, said second conveyor means constituting two conveyor units each having its own loading and discharge ends, one of said conveyor units having its loading end positioned in grain flow communication with said drying unit outlet and having its discharge end positioned in grain flow communication with the loading end of the other of said conveyor units wherein grain is received from said drying unit by said one conveyor unit and carried thereby to the other conveyor unit, means anchoring the loading end of said other conveyor unit to said frame for permitting universal pivotal movement of said other conveyor unit and the shifting of both ends thereof, means for moving said other conveyor unit so as to permit the discharge end of said other conveyor unit to be shifted into a selected location spaced from said dryer unit, means anchoring the loading end of said one conveyor unit to said frame for permitting pivotal movement of said one conveyor unit, means for moving the discharge end of said one conveyor unit into grain flow communication with the loading end of said other conveyor unit to accommodate movement of said other conveyor unit when said other conveyor unit is shifted into said selected location.
Claim 3
Dependent Claim
106 words
A dryer of claim 1 and support means carried by said frame for engagement with said second conveyor means to position said second conveyor means longitudinally of said frame when the grain dryer is stored or is being pulled from one location to another, second conveyor means connecting means positioning the loading end of said second conveyor means at said drying unit outlet, said connecting means having releasable parts to permit the disconnection of said second conveyor means wherein the loading end thereof may be shifted from said drying unit outlet while said second conveyor means is supported longitudinally of said frame by said support means.
Claim 4
Dependent Claim
84 words
The dryer of claim 1 wherein said holding bin includes a funnel-shaped side wall having a lower open end and a grain collection pocket positioned below said open end, the loading end of said first conveyor means received within said collection pocket, the discharge end of said first conveyor means positioned in grain flow communication with the inlet of said drying unit, said collection pocket including a vertical side wall angularly positioned relative to said holding bin side wall And a horizontal bottom wall.
Claim 5
Dependent Claim
31 words
The dryer of claim 3 wherein said bottom wall is shiftably carried by said pocket side wall and constitutes a door which is normally closed during use of said grain dryer.
Claim 6
Dependent Claim
80 words
The dryer of claim 1 and including a grain deflector carried within said holding bin adjacently above the loading end of said first conveyor means, said holding bin including a side wall, said grain deflector having circumferential edges spaced from said side wall, means for shifting said grain deflector to vary the spacing between said edges and side wall whereby the flow of grain around said deflector and into the loading end of said first conveyor means may be regulated.
Claim 7
Dependent Claim
45 words
The dryer of claim 1 and including jacking devices positioned at each side of said frame, said jacking devices connected to said frame and having parts extendible into ground contact for supporting the weight of said bin and drying unit during use of said dryer.
Claim 8
Dependent Claim
31 words
The dryer of claim 1 and a fuel tank carried by said frame for supplying fuel to said drying unit, said holding bin being positioned between said drying unit and tank.
