A cotton harvesting machine which utilizes a novel structure for pulling the mature cotton plant from the burr includes a plurality of paired rotating disks mounted on a drive shaft for rotation in the same relative direction as the movement of the cotton plant through the picking area of the machine, each disk pair being moved into an open position whereby the cotton plant is funnelled between the open disk pair and a closed position whereby the disk pair grips the mature cotton and pulls it from the burr. The opening and closing movement of each disk pair is provided by a pair of cams and associated cam followers, one for each disk in the pair, each cam being mounted in a stationary position around the rotating drive shaft, the cam followers being fastened to each disk and following a path of movement along a cam track during the rotation of the shaft. The cam tracks associated with each pair of cams converge and diverge around the shaft causing the closing and opening position of the disk pair as the cam followers move in the track. An adjusting mechanism can be provided to change the relative positions between opposing disks by relative movement of the associated pair of cams.
A harvesting machine for cotton comprising means including a pair of opposed disks capable of gripping a cotton plant therebetween and pulling the cotton off the plant, means for separating the paired disks to allow the cotton plant to enter therebetween and then close the paired disks once the cotton plant is in the picking area, said paired disks being mounted for rotation on a rotating shaft, drive means for said rotating shaft, said paired disks comprising an upper disk and a lower disk, said means for separating and closing said disks comprising at least one cam containing a cam track and a cam follower associated with one of said upper or lower disks and said cam track.
A harvesting machine for cotton comprising a mechanism for picking the mature cotton from the cotton plant, said picking mechanism including a plurality of pairs of opposed disks capable of gripping the cotton plant therebetween and pulling the cotton off the plant and said picking mechanism further including means for separating the paired disks to allow the cotton plant to enter therebetween and then close the paired disks once the cotton plant is in the picking area, said paired disks being mounted for rotation on a vertical rotating shaft, drive means for said rotating shaft, said plurality of paired disks forming at least a single row of paired disks along a vertical extent of said rotating shaft, said rotating shaft containing more than one row of paired disks, said rows of paired disks being spaced vertically along said shaft, said paired disks comprising an upper disk and a lower disk, said means separating and closing said disks comprising at least one cam means containing a cam track and a cam follower associated with one of said upper or lower disks and said cam track.
