Abstract
The crop gathering reel of a combine is mounted on a pair of reel support arms each in the form of a hydraulic piston and cylinder assembly having widely spaced load-bearing lands which enable the arms to withstand the bending loads arising from supporting the reel in cantilever fashion while permitting adjustment of the reel position forwards and rearwards.
Claims11
Crop gathering apparatus comprising:
- a crop gathering platform;
- a crop gathering reel;
- and
- a pair of reel support arms, one arm at each end of the crop gathering reel, the reel being mounted on the crop gathering platform by said reel support arms, said reel support arms extending forwardly with respect to the direction of usual forward motion of the crop gathering apparatus, said reel support arms also being length-adjustable to provide forward and rearward adjustment of the position of the reel relative to the platform;
- characterized in that
- at least one of said reel support arms comprises first and second sliding members forming part of a piston and cylinder assembly actuable by hydraulic fluid;
- and that
- load bearing lands are formed within said piston and cylinder assembly on one of said sliding members, said load bearing lands being spaced apart axially with respect to the longitudinal axis of the piston and cylinder assembly;
- and that
- the piston of said piston and cylinder assembly is slidably supported on said load bearing lands for movement relative to the cylinder thereof without changing the axial spacing of said lands whereby said lands can support bending loads imposed on the piston and cylinder assembly by the weight of the reel.
