摘要： A reinforced feeder housing for an agricultural machine includes a housing body having a top surface, a bottom surface, and two opposing side surfaces each extending between the top and bottom surfaces. The housing body includes a front opening through which crop material is directed into the feeder housing from a header of the agricultural machine, and a rear opening that is substantially opposite the front opening through which crop is expelled from the feeder housing and is delivered to a threshing mechanism of the agricultural machine. Various panels of the housing body are reinforced to improve the structural integrity of the feeder housing and prevent damage to the welds in the housing body.

摘要： A crop processing assembly comprises a tube-shaped cage structure and a threshing and separation rotor (7) mounted in said cage structure. The cage structure comprises one or more curved gratings (10) at the bottom and a cover (16) at the top, so that the rotation of the rotor actuates the movement of crops along a helicoidal path through the gap between the rotor and the cover and gratings. Inclined guide vanes (30) are preferably arranged on the inner surface of the cover to provide guidance to the crops. The cover comprises a step (17) between an upstream portion (16a) of the cover and a downstream portion (16b) of the cover, so that the gap between the rotor and the cover is larger in the downstream portion than in the upstream portion. The step is oriented at an oblique inclination angle (α), when the cover is regarded in a parallel projection view from a position above the step. The inclination angle is configured so that the step (17) has the function of guiding the crops along the helicoidal path. When guide vanes are present, the step itself performs the same function as the vanes, so that the mounting of one or more additional vanes in the stepped transition area is not required.
