COMBINE RIPPLE PAN

摘要

The invention provides an improved ripple pan which compensates for the over-deposition of threshed grain onto the outer portions of the grain pan by channeling the grain to the center of the pan. The pan has a central section with ripples that are perpendicular to the flow of the grain, and two outer sections with outer edges that are elevated above the central section. The ripples on the two outer sections are biased such that the outer edges of the ripples are located rearward of the inner edges of the ripples. An alternate embodiment of this invention solves the problem of excessive grain deposition in the central section of the ripple pan. This embodiment has two outer sections configured similarly to the first embodiment and a central section with a center peak which slopes downward on either side of the peak to the inner edges of the outer sections.
