Patent number: 10986780Abstract: A cotton cleaner for cleaning cotton harvested by a cotton stripper comprises grid bars, a saw drum, and a buffer ring. The saw drum is positioned in proximity to the grid bars and rotatable about an axis of rotation of the saw drum for saw teeth of the saw drum to remove cotton from harvested cotton plant material that passes between the saw drum and the grid bars. The buffer ring is supported by and disposed around the saw drum such that an outer diameter of the buffer ring is greater than an outer diameter of the saw teeth for contact of a grid bar of the grid bars with the buffer ring upon deflection of that grid bar toward the saw drum.Type: GrantFiled: May 10, 2019Date of Patent: April 27, 2021Assignee: Deere & CompanyInventor: John O. Rumohr

Patent number: 10531612Abstract: Cotton cleaner assembly with saw drum and releasable grid bar mechanism that includes bars and a release mechanism that moves the bars between operational and released positions is disclosed. In operational position, the release mechanism locks the bars in a fixed position relative to the saw drum to knock debris from cotton that rotates with the saw drum. In released position, the release mechanism moves the bars away from the saw drum to enable blockages that interfere with saw drum rotation to be cleared. The grid bar mechanism can include side members, where the bars extend between the side members, and the release mechanism moves the side members. The release mechanism can manually or hydraulically pivot the side members about pivot points against and away from stops. The pivot points and stops can be adjustable to adjust distance between the bars and saw drum in the operational position.Type: GrantFiled: May 23, 2017Date of Patent: January 14, 2020Assignee: DEERE & COMPANYInventors: John O.
