A combine harvester including a grain pan arranged to catch a crop stream from threshing or separating apparatus. The grain pan is driven in an oscillating manner to convey the crop stream rearwardly to a rear edge. A cleaning unit including a fan for generating a cleaning airstream which is directed under the rear edge of the grain pan. The grain pan comprises includes a transversely corrugated surface and longitudinal gullies having a curved profile for compensating for side-hill operation.

A tubular for processing crops can include a body having an outer surface and protrusions extending outwardly from the outer surface. The protrusions can be arranged in bands that are spaced apart along the outer surface to define gaps therebetween that form grooves extending around a circumference of the body. Each band of protrusions can be positioned offset with respect to at least one adjacent band of protrusions such that the protrusions form a spiraling configuration around a longitudinal axis of the body.

Stalk rolls are used for a corn harvester or combine having a chassis, an engine, a cab mounted to the chassis with a head mounted at the front of the body. The head includes an auger, row separators, corn stalk gathering assemblies between the row separators and ear removal assemblies. Each ear removal device includes a pair of stalk rolls. Each stalk roll has a core and longitudinally extending flutes about a periphery of the corn extending along the core. Each stalk roll has a straight first section and a tapered second section. The flutes on each stalk roll have different lengths and end at different locations at the front of the stalk roll. The flutes of the stalk roll may also have notches and different shaped leading edges.

An intelligent system and a method for coordinating harvester and logistics vehicle are illustrated. The intelligent system comprises a harvester terminal and a logistics vehicle terminal. The harvester terminal comprises a repository monitoring module and a control module, wherein the repository monitoring module monitors storage information of a storage bin of the harvester. The control module receives the storage information from the repository monitoring module, and determines whether the storage location of the storage bin of the harvester reaches a preset location. The harvester terminal and the logistics vehicle terminal are communicatively connected. When the storage location of the storage bin of the harvester reaches the preset location, the control module sends a transport instruction to the logistics vehicle terminal to control the logistics vehicle to transport grain, thereby achieving intelligent coordination between the harvester and the logistics vehicle.

Convection interactions like exposure of seeds to hot ozonated air, hot humidified air, hot ozonated humidified air and optional ultrasoundobtain higher net reduction of germination viability (0-1 percent germination versus 70 percent obtained for a control) of seeds than that obtained via a seed illumination process alone that uses Medium Wavelength Infrared and an Indigo Region Illumination Distribution.
