Crop harvesting combine

Claim 2

A combine harvester for grain crops comprising a main support frame for mounting thereon crop gathering and threshing devices, said main support frame including transversely spaced, upstanding main side frame members and a top connecting structure which extends between the tops of said side frame members and cooperates therewith to define a compartment for housing said threshing devices, said top connecting structure constituting an integral part of said main support frame and forming a grain storage bin structure with substantially the entire floor of said grain storage bin structure forming a roof for said compartment, and said grain storage bin structure having sidewalls upstanding from said floor and extending above said compartment so as to provide storage space the major portion of which is directly above said compartment for temporarily storing a predetermined quantity of grain.

Claim 3

A crop harvester comprising a vehicle having a main frame adapted to support apparatus for gathering and threshing grain crops, said main frame including upstanding structural side frame elements on opposite sides of the vehicle which are spaced so as to define the sides of a bottom compartment for housing the crop threshing apparatus, and a bin structure for storage of grain resulting from the operation of the threshing apparatus, which bin structure is constructed as an integral part of said main frame with a floor forming bottom wall portion connecting the top portions of the side frame elements and substantially the entire floor forming also a roof for said compartment, said bin structure having its major grain accommodating area extending above said compartment and including side and end walls upstanding from said bottom wall and laterally spaced, longitudinal auger troughs and an unloading cross trough on said bottom wall, said cross trough having a connection with the longitudinal troughs so as to enable grain to be fed from the longitudinal troughs into the cross trough.

Claim 4

A crop harvester comprising a vehicle having a main frame adapted to support apparatus for gathering and threshing grain crops, said main frame including upstanding structural side frame elements on opposite sides of the vehicle which are spaced so as to define the sides of a bottom compartment for housing the crop threshing apparatus, and a bin structure for storage of grain resulting from the operation of the threshing apparatus, which bin structure is constructed as an integral part of said main frame with a floor forming bottom wall portion connecting the top portions of the side frame elements and substantially the entire floor forming also a roof for said compartment, said bin structure having its major grain accommodating area extending above said compartment and including side and end walls upstanding from said bottom wall and laterally spaced, longitudinal auger troughs and an unloading cross trough on said bottom wall, said cross trough having a connection with the longitudinal troughs so as to enable grain to be fed from the longitudinal troughs into the cross trough.

Claim 5

A combine harvester as set forth in claim 2, wherein said grain storage bin structure extends on opposite sides of said main support frame and includes a bottom wall with portions which are inverted V-shaped in cross section so as to provide said longitudinal auger troughs which extend along the sides of said bottom wall and above said compartment and said cross trough constituting an unloading auger trough extending along one end of the bottom wall of said storage bin at an elevation to receive grain from said longitudinal auger troughs and having an auger therein to move the grain laterally out of said storage bin.
