  • mounting block 12 and blade 14, including trunk 16 and foot 18, are elongate in a generally vertical first plane A.
  • the first plane includes longitudinal axis A'.
  • the outer surface of trunk 16 smoothly merges into, so as to truncate in cross-section as, a waisted or foot-shaped lower surface 24.

  • the plane of symmetry of trunk 16 coincides with the first plane.
  • Channels 36 and 38 may, in one preferred embodiment not intended to be limiting, be formed by the alignment and snug adjacency of flanges 42 and 44 on the inner sides of access panels 26 and 28 respectively when the access panels are mounted conformally in opposed relation, to the lateral sides of trunk 16 so as to cover cavity 46 in trunk 16.

  • the rear-most end of foot lower surface 24 is upturned for example as to provide aperture 70 with an opening generally perpendicular to the longitudinal axis of channel 40.
  • channels 36, 38 and 40 are generally parallel so as to be raked aft in a downward direction from ports 30, 32 and 34.
  • Upper surfaces 20a and 22a extend aft and are cantilevered outwardly over the aft apertures of interior ducts 62 and 64.
  • the aft apertures of interior ducts 62 and 64 are advantageously formed by reducing the longitudinal length of lateral side walls 20b and 22b and raking the rearmost edge of lower surfaces 20c and 22c so as to extend (hem contiguously aft from the rear edge of lateral side walls 20b and 22b respectively to blend with foot 18.
  • Figure 3b canards 21 , and the passing of foot 18 in their form as described herein, causes a fluid-like circulation in direction D of soil 78 aft of wings 20 and 22. It is understood that the view of Figure 7 is an approximation of the cross-section through the soil immediately behind blade 14 as it is translating through the soil. The soil, acting in a fluid manner, collapses so as to drop down shoulders 84 as the soil beneath shelves 82 is circulated in counter-rotation in direction D.
  • this circulation transports seeds 88 laterally outwardly along shelves 82 so as to facilitate advantageous lateral spacing apart of seeds on either side of furrow 80 separated both laterally and vertically from fertilizer 86 so as to inhibit chemical burning of the seeds for example by reason of the spacial relationship approximated by the illustration of Figure 8.
  • ports 30, 32 and 34 may be changed as would be known to one skilled in the art so as to introduce, for example, seeds through ports 30 and 32 and water through port 34.
  • ports 30, 32 and 34 would have to be attached by appropriate conduits to corresponding hoppers or reservoirs carried, for example on a tractor (not shown) or trailer.
  • blade 10 is mounted to an actuating linkage 1 10 whereby the blade may be lowered into the soil 78 or elevated out of contact with soil 78.
  • Actuating linkage 1 10 is a parallelogram linkage for displacement in direction I of header assembly 1 12, specifically members 1 12a and 1 12b relative to hanger apparatus 1 14.
  • the members are pivoted relative to hanger apparatus 1 14 on pivotally mounted upper drag arms 1 16 and lower drag arms 1 18.
  • Each opposite end of the upper and lower drag arms are pivotally mounted by means of pins, bolts or the like.
  • upper drag arms 1 16 are mounted at one end to members 1 14a and 1 14b of hanger apparatus 1 14 by means of pin 120.
  • the opposite end of upper drag arms 1 16, which include parallel arms I 16a and 1 16b, are mounted between the upper ends of side plates 1 12a and 1 12b by means of pin 122.
  • Lower drag arms 1 18 include an opposed pair of parallel rigid arms 1 18a and
  • Coulter wheel 130 is rotatably mounted on shaft 128, so as to sandwich the lower forward corners of header members 1 12a and 1 12b by means of a pair of mounting plates 133.
  • the coulter wheel is not free to swivel relative to blade 10, but rather is held aligned, generally co-planar, with the blade.
  • the parallelogram linkage of upper drag arms 1 16 and lower drag arms 1 18 and header members 1 12 are actuated so as to rotate in direction I about hanger apparatus 1 14 by, in one embodiment, selective actuation of hydraulic ram 138.
  • Hydraulic ram 138 is fed by high pressure hydraulic lines (not shown) as would be known by one skilled in the art.
  • the upper end of hydraulic ra 138 is rigidly mounted to hanger apparatus 1 14, specifically, between the upper ends of hanger members 1 14a and 1 14b.
  • the lower end of hydraulic ram 138 is pivotally between upturned lower ends of upper drag arms 1 16 by means of pinned coupling 144.
  • Extension of hydraulic ram 138 causes rotation of the upper and lower drag arms downwardly, about pins 120 and 124, relative to hanger apparatus 1 14. Retracting so as to shorten hydraulic ram 138 rotates the upper and lower drag arms upwardly.
  • FIG. 9- 15 employing the blade of Figure 3b, flanges 12a' interlock with corrugations, grooves or channels 146a on the interior surfaces of the side plates 146 of the header assembly 1 12. Side plates 146 are clamped together so as to sandwich flanges 12a' and the upper end of blade 10 by means of bolts 148. Bolts 148 extend through elongate apertures 150 in side plates 146 and bolt holes 152 in the upper end of blade 10. Apertures 150 are vertically elongate so that the vertical position of blade 10 relative to side plates 146 may be adjusted, for example to compensate for erosive wear of coulter wheel 130.
  • a closure assembly 160 is mounted between header members 1 12a and 1 12b.
  • L-shaped arm 162 has its elbow pivotally mounted on pin 164 at the upper rear end of side plates 146, between members 1 12a and 1 12b.
  • a closing wheel 132, or pair or plurality of such wheels are rotatably mounted to the lower rearward end of arm 162 so as to press down into engagement with the upper surface of furrow 80 formed behind blade 10 as blade 10 passes through soil 78. Downwards pressure is applied to wheel 132 by the force of actuator 138 and/orthe weight of linkage assembly 1 10 and blade 10.
  • Arm 162 is maintained in its angular position about pin 164 by means of arm 166, better seen in Figure 1 1 , mounted to header member 1 12b.
  • Arms 162 and 166 may be releasably pinned together by a manually releasable pin 168.
  • Pin 168 may be removed to allow angular adjustment between arms 162 and 166, pin 168 being selectively insertable into an array of holes 170 along the rear end of arm 166.
  • Selectively positioning the upper end of arm 162 outwardly along arm 166 rotates wheel 132 downwardly relative to header assembly 1 12 about pinned shaft 164 so as to selectively and adjustably apply a downward pressure against the upper surface of furrow 80.
  • the supporting frame structure 186 supporting bars 182 is preferably mounted on wheels 188 so that the entire structure may be towed by a tow coupling 190 or otherwise mounted to a tractor (not shown) or the like thereby simultaneously pulling a laterally spaced apart array of blades 10 through soil 78.
  • the supporting frame structure 186 may also be used to support hoppers 192 on supporting legs 194.
  • Hoppers 192 supply granular material such as seed or fertilizer to metering devices 196 mounted beneath the hoppers so as to feed, via conduits 198 such granular material into blade apertures 30, 32 and 34 forming the infeed inlets into blades 10.
  • conduits 198 are omitted, with the exception of those extending from the metering devices 196 most closely in the foreground in order to maintain a clear view of the arrays of linkages 1 10 mounted to the parallel laterally extending bars 182.
  • a work platform 200 and an associated ladder may also be mounted to legs 194 so as to provide ease of access to for example hoppers 192.
  • FIGs 13 and 14 One advantage of the inline arrangement of coulter wheels 130 and corresponding blades 10 is also illustrated in Figures 13 and 14.
  • the leading edge of blades 10 are, as also seen in Figures 15 and 16, mounted adjacent to the outer circumference of the coulter wheel.
  • the term adjacent in describing the spatial relationship between coulter wheel 130 and blade 10 means that the distance di between the outer circumference of coulter wheel 130 and the point of the toe on the leading edge of blade 10 is sufficiently narrow so that large rocks or boulders will not become jammed therebetween.

Abstract

La présente invention concerne un système enterré intégré d'ensemencement, de fumure et d'arrosage comportant une lame se montant dans un organe de coupe d'un attelage parallélogramme. Deux bras de rouleaux brise-mottes parallèles rigides allant de l'organe de coupe à l'ensemble étrier de suspension sont clavetés à leurs extrémités respectives de façon que la rotation de l'organe de coupe par rapport à l'ensemble étrier de suspension monté sur les bras parallèles conserve à l'organe de coupe une orientation générale horizontale, maintenant ainsi une orientation constante à la lame enfoncée. L'ensemble étrier de suspension peut se monter sur un châssis support. Un actionneur sélectif permet la commande sélective de la force d'enfoncement de la lame dans le sol. Un coutre circulaire aligné est monté sur l'avant de la lame, dans son alignement de façon à se trouver sensiblement dans le même plan qu'elle. Le flanc arrière du coutre circulaire est voisin du flanc avant de la lame.
