Definitions

  • the rotating stalk rolls 50, 52 rapidly pull the com stalks 16 downwardly through the slot 44 between the stripper plates 40, 42 such that when the com ears 14 engage the stripper plates 40, 42, the ears 14 are pulled or stripped from the cornstalks 16.
  • the cornstalk 16 is pulled downwardly through the slot 44 and is returned to the field below the header 20 as the combine drives forwardly (FIG. 2).
  • the stripped ears 14 which remain on the stripper plates 40, 42 after the cornstalk 16 is pulled through the slot 44 are then conveyed by the lugs 36 of the gathering chains 32, 34 upwardly and rearwardly to the trough 23 and cross-auger 24.
  • FIG. 14B is an enlarged partial exploded perspective view of the differential speed stalk roll assembly of FIG. 7 showing the shafts.
  • FIGs. 29A-29C are perspective and plan views of the annular knife of the smaller diameter stalk roll of FIG. 24.
  • FIGs. 30A-30C are perspective and plan views of the annular knife of the larger diameter stalk roll of FIG. 24.
  • FIG. 32 is a perspective view of the differential speed stalk roll assembly of FIG. 31 with some of the modular body segments removed to show the interior of the stalk rolls.
  • FIGs. 37A is a front elevation view of an embodiment of the knife blade of the smaller diameter stalk roll of FIG. 31 showing the knife blade segments together.
  • each stalk roll 110, 120 may be formed by casting, forging, or machining the main body 112, 122 separate from the head 114, 124.
  • each stalk roll body 112, 122 may comprise modular body segments (discussed later) with each modular body segments cast, forged, machined or otherwise fabricated as an interchangeable unit.
  • the modular body segments may be cylindrical or conical segments or plate steel or bar stock segments which are welded or bolted together.
  • the sleeve 180 has an internal configuration (not shown) that matingly receives the external configuration of the shafts 113, 123, including a keyed internal periphery that matingly receives external splines 182 on the shafts, such that the sleeve 180 is rotationally restrained with respect to the shafts 113, 123.
  • the sleeve 180 is also longitudinally restrained with respect to the shaft by roll pins or threaded connectors extending through apertures 184 in the sleeve 180 that align with apertures 186 in the shafts 113, 123.
  • the head 214, 224 may have helically arranged flights 216, 226 which function as augers to pull the cornstalk rearwardly between the main bodies 212, 222 as the stalk rolls rotate counter to one another as indicated by arrows 211, 221 (FIG. 25).
  • each stalk roll 210, 220 receives and is rigidly secured to laterally spaced shafts 213, 223 coupled to the gearbox 125 which drives rotation of the shafts about their respective longitudinal axis 217, 227.
  • the tapered forward most ends of the plate segments 270-1, 270-2 results in a wider spacing between the flutes 240 of the stalk roll bodies 212, 222 at the forward end, such that the larger diameter portions of the cornstalks toward the ground surface are able to feed more readily into the stalk roll assembly 200. Additionally, the tapered forward ends of the stalk roll bodies 212, 222 results in less of a differential speed between the first and second stalk rolls 210, 220 at their forward most ends which also allows the cornstalks to enter the stalk roll assembly 200 before the action of the differential speeds becomes aggressive.
  • This difference in diameters between the first and second stalk roll bodies 312, 322 results in a differential speed between the first and second stalk rolls 310, 320 which produces the desired shredding of the cornstalks 16 during harvesting as described above in connection with the stalk roll assembly 100. It should also be appreciated that the tapered forward most end of the plate segments 370-2 results in a wider spacing between the flutes 340 of the stalk roll bodies 312, 322 at the forward end, such that the larger diameter portions of the cornstalks toward the ground surface are able to feed more readily into the stalk roll assembly 300.
  • the first and second stalk rolls 310, 320 may be desirable for the first and second stalk rolls 310, 320 to have the same diameters or about the same diameters at their forward ends such that there is more space between the opposing flutes at the forward end to receive the larger diameter portion of the cornstalks 16 as they enter the stalk roll assembly 300 and such that there is minimal or no differential speed between the stalk rolls at the initial point of entry. But after the initial entry, the diameter of the second stalk roll 320 increases longitudinally rearwardly, in either a gradually increasing taper or a stepped taper until reaching the desired diameter to produce the desired differential speed between the adjacent stalk roll bodies 312, 322.
  • one or both of the main bodies 412, 422 may include one or more knife blades 450 spaced longitudinally along their length and defining one or more knife planes normal to the axes of rotation 417, 427 of the main bodies 412, 422.
  • the forward plate segment 470- 1F has a substantially uniform forward width“Wl-F” from its forward end toward the rearward end for about 1/3 the length of the first body 412 before flaring outwardly and rearward to provide an intermediate width“Wl-F as a transition between the narrower forward width Wl-F to the wider rearward width Wl-R.
  • the forward plate segment 470-1F may have an intermediate plate 470-3F welded thereto such that when the segment plates 470- 1F are mounted to the blocks 460, the outer ends of the plate segments 470-1F and 470-3F are substantially equally radially spaced.
  • the forward plate segment 470-2F has a substantially uniform intermediate width“W2-I” that is substantially the same as the rearward width W2-R which continues from its rearward end toward the forward end before tapering inwardly to the forward most end to a forward width W2-F.
  • the forward width W2-F is substantially the same width as the forward width Wl-F of the first stalk roll body 410.
  • the forward plate segment 470-2F may have an intermediate plate 470-4F welded thereto such that when the segment plates 470-2F are mounted to the blocks 460, the outer ends of the plate segments 470-2F and 470-4F are substantially equally radially spaced.
  • the modular body segments 470 may have a series of longitudinally spaced slots 476 as shown in FIG. 54, which allows the operator to place one of the knife blades in one of the series of longitudinally spaced slots to achieve the desired gap between the back-to- back knife blades 450.
  • a tight gap (either laterally or longitudinally) will result in complete cutting or severing the stalk into individual pieces, whereas a wider gap (either laterally or longitundinally) which will only partially cut or sever the stalk resulting in a“chain” of partially severed stalk pieces.
  • the gaps between knife blades may vary along the length of the stalk roll.
  • the lateral gaps between the knife blades can be achieved by selecting from different diameters of knife blades 550 and selecting from corresponding modular body segments 570 having different depths of slots 576.
  • the longitudinal gaps between the knife blades can be achieved by moving one of the knife blades longitudinally from the opposing knife blade on the adjacent stalk roll.

Abstract

La présente invention concerne des cylindres à tiges à vitesse différentielle pouvant être montés sur une unité de rang d'une tête pour culture en rangs. Un premier corps de cylindre à tiges présente une vitesse périphérique externe inférieure à la vitesse périphérique externe d'un second corps de cylindre à tiges dans une relation espacée latéralement. Les corps de cylindre à tiges peuvent avoir des segments de corps modulaires et interchangeables de différentes configurations.
