Patent number: 4489733Abstract: A combine for harvesting and threshing grain has features to prevent grain and time wastage even if the combine is tilted sideways, and other features to simplify the threshing equipment. The combine has a sieve housing that is mounted on rollers to the frame. These rollers allow the sieve housing to swing like a pendulum if the combine tilts sideways. The combine has inner and outer cylindrical bodies that rotate together opposite to the rotation of a threshing drum. The threshing drum and grate are conical with the rearward end being smaller than the forward end. A beater for beating grain rotates with the threshing drum, causing grain to fall through slots located in the inner body. The space between the inner and outer body contains a helical flight for transporting this rescued grain back to the forward end and to the sieves. Elevating rings mounted to the outer body rotate with the outer body to lift material from the sieve to the bin, if clean grain, and back to the threshing grate, if tailings.Type: GrantFiled: August 18, 1982Date of Patent: December 25, 1984Assignee: Probe Adventures, Inc.Inventor: Mark R.
