A combine harvester, having threshing and separating means for threshing and separating crop material and a cleaning apparatus disposed to receive threshed and separated grain from said treshing and separating means and being operable to clean unwanted residue from the threshed and separated grain is disclosed wherein the cleaning apparatus, including at least a pair of cleaning sieves arranged to be oscillated generally back-and-forth for moving threshed and separated grain therealong while permitting the passage of cleaned grain therethrough, and further including a cleaning fan operable to direct a cleaning air blast to the cleaning sieves for urging unwanted residue to the threshed and separated grain into an airborne state for discharge from the combine harvester, is provided with an agitator positioned between the cleaning sieves. During operation, the cleaning sieves are moved relative to the agitator for removing straw particles that otherwise might tend to stick to one or both sieves in a generally upright orientation.

Combine harvester cleaning apparatus

A combine harvester is disclosed wherein the operative components thereof are built according to a modular concept. The combine harvester includes a threshing module, a separating module and a cleaning module, all of which are supported by a frame and operably interconnected. Each respective module is interchangeable with a like module having a different configuration.

A combine harvester having a straw chopper disposed at the rearward end thereof is disclosed wherein the drive mechanism for the straw chopper includes a driving member, a driven member and intermediate member located between the driving member and the driven member such that there is an angled line of drive between the driving member and the driven member. A first flexible drive transmission member extends between the driving member and the intermediate member. A second flexible drive transmission member extends between the intermediate member and the driven member. A first tensioning mechanism is operable to move the intermediate member in a direction to tension the first flexible drive transmission member. A second tensioning mechanism is operable to move the intermediate member in a direction to tension the second flexible drive transmission member.

According to the present invention a harvesting machine comprises a chassis with threshing and separating means and a power source mounted thereon and a grain tank pivotally mounted whereby it can be tipped to discharge grain contained therein rearwardly of the machine. The harvesting machine further also comprises a grain cleaning means mounted on the chassis and a conveyor means for loading grain into the grain tank. The conveyor means comprises a lower elevator extending from the grain cleaning means to the grain tank, an upper elevator mounted within the grain tank and aligned with the lower elevator when the grain tank is in the grain loading position, and disengageable coupling means disposed between the lower and upper elevators.

The invention relates to a rotary air filter for use in combination with a cooling radiator or another cooling device and which has to operate in a dusty atmosphere. The rotary air filter comprises a hollow rotary structure having a perforated rotary filter element mounted on the intake side of a fan operable to draw air through the filter element, the rotary structure having a generally unobstructed inner surface lengthwise thereof, and a discharge opening being provided adjacent the fan and generally in line with said unobstructed inner surface for enabling the discharge therethrough of foreign material entering through the perforations in the rotary filter element.
