US 5,471,826 A · Moistener column for a cotton harvester

Abstract

A pivoting moistener column for a cotton harvester having a locking feature which operates without tools which automatically releases the column for swinging toward an access position when a service door is opened and which retains the column securely in the operating position when the service door is closed. Preferably the locking feature includes a pair of mating upright flanges, one connected to the service door near a service door pivot and the other connected to the moistener column opposite a moistener column pivot. The column is located near an outer wall of the harvester row unit housing and is substantially outside of the housing when in the service position. A fluid distribution system mounted on the column is supported outside of the housing in both the operating and service positions. Panel structure on the column forms a relatively smooth, continuous barrier with the service door for good cotton/cotton plant flow past the column.

Dependent claims

In a cotton harvester having a row unit with cotton harvesting structure including an upright spindle drum supported within a row unit housing, the housing having an outer wall and defining a row receiving area, the spindle drum including a plurality of spindles movable in a path which passes through the row receiving area, and an upright moistener column with moistener pads for cleaning the spindles, column support and locking structure comprising:

a column support supporting the moistener column from the housing for movement between an operating position wherein the moistener pads are located within the housing adjacent the path of the spindles and an access position wherein the column is supported from the housing with the pads offset outwardly from the spindle path and outwardly of the housing;
column securing structure having an unlatching position and a latching position, wherein the securing structure in the latching position maintains the column in the operating position and in the unlatching position facilitates movement of the column to the access position;
and
further including a service door supported by the housing and movable between an open position for providing access to the harvesting structure and a closed harvesting position, wherein the column securing structure comprises a contact member connected to the service door.
