Definitions

  • This invention relates to the field of no-tillage opening blades which may be partially submerged into earth, for example in a farmers field, so as to pass the blade at a submerged depth for delivery of seeds, fertilizer or water into the earth.
  • This invention relates to blade delivery systems which have replaced tillage plows and the like. It is known that the use of plows or other devices having for example tillage discs for tilling the earth or otherwise opening and turning a furrow through the ground suffer from the disadvantage that the moisture in the soil is unnecessarily exposed to evaporation. In the past it was necessary to open the earth so that the ground beneath the surface could be seeded, fertilized and watered. Whether this was accomplished by machinery or done manually, prior art machines or manual systems also suffered from the disadvantage that fertilizer was typically delivered into close proximity to the seeds being sown occasionally resulting in the seeds becoming chemically burnt.
  • the sub-surface seeding, fertilizing and watering device of the present invention includes an opening blade having first and second sides extending between a leading edge and an aft edge.
  • the first and second sides are advantageously generally symmetrical to each other on either side of a first plane, where the first plane generally bisects the opening blade, and the leading edge and the aft edge lie generally in the first plane.
  • the opening blade has an upper surface and a lower surface extending between upper and lower edges respectively of the first and second sides of the blade.
  • First and second wings are mounted to the first and second sides respectively in generally oppositely disposed relation so as to be cantilevered outwardly therefrom.
  • the first and second wings extend between first and second forward wing edges and first and second aft-opening wing apertures in the first and second wings respectively.
  • the first and second wings are mounted to the first and second sides at, respectively, first and second distances from the lower surface measured generally parallel to the first plane.
  • the opening blade has therethrough, and generally lying in the first plane, first and second conduits, extending from, and cooperating with, at uppermost ends thereof, first and second infeed ports in the upper surface.
  • the first and second conduits cooperate with, at lowermost ends thereof, first and second wing ducts extending aft through the first and second wings respectively between the lowermost ends of the first and second conduits and the first and second aft opening wing apertures.
  • the first and second conduits and the corresponding first and second wing ducts are thereby in material flow communication between the first and second infeed ports and the corresponding first and second aft opening wing apertures for seed, fertilizer or fluid flow, as fed from a material feeder, therethrough during the forward translation of the blade.
  • the opening blade is mountable to the material feeder so as to be generally vertically disposed, when mounted thereon, for partial submerging into soil to a first submerged depth advancing the leading edge through the soil.
  • the first and second distances are less than the first submerged depth so that the first and second wings are submerged in the soil during the forward translation of the blade.
  • the opening blade further includes a third conduit extending in material flow communication between a third infeed port in the upper surface and an aft opening blade aperture in a rearward position on the opening blade in proximity to the aft edge for seed, fertilizer or fluid flow therethrough, as fed from the material feeder.
  • the aft-opening blade aperture is centrally disposed relative to the first plane so as to lie generally symmetrically across the first plane, and may be positioned to aperture intersect the lower surface of the blade.
  • the aft-opening blade aperture is formed at the intersection of the lower surface and the aft edge of the blade.
  • the aft-opening blade aperture may lie in a second plane at generally 30° inclined relative to a third plane generally containing the lower surface of the blade, wherein the third plane is generally orthogonal to the first plane.
  • first, second and third conduits are generally parallel and raked aft of their corresponding first, second and third infeed ports.
  • the first, second and third conduits may be raked aft at an angle of approximately 55° relative to a fourth plane generally containing the upper surface of the blade if the upper surface is a planar generally horizontal surface, although this is not necessarily so.
  • At least the first and second conduits are formed by mating of corresponding opposed facing channels in oppositely mounted side panels, oppositely mounted in, or mountable into, first and second sides of the blade.
  • the third conduit is generally parallel and adjacent the aft edge and the leading edge is concavely curved and forms a pointed toe at the intersection of the leading edge and the lower surface of the blade.
  • the pointed toe may be made of hardened material relative to the hardness of material forming the balance of the opening blade.
  • the opening blade may be defined as having a longitudinal length dimension and a height dimension, where the longitudinal length dimension is perpendicular to the height dimension and both dimensions lie in the first plane. Further, the opening blade has a lateral width dimension perpendicular to the first plane.
  • the longitudinal length dimension extends between the leading and aft edges of the blade, the height dimension extends between the upper and lower surfaces of the blade, and the lateral width dimension extends between the first and second sides of the blade.
  • the length dimension is much, that is, significantly greater than the width dimension, as described hereinafter.
  • the height dimension in one embodiment is greater than the submerged depth so that the blade is supported above the soil and the blade thus partially submerged during forward translation, although this is not intended to be limiting. That is, it is readily conceivable to mount the blade to a support that itself becomes partially submerged in the soil.
  • first and second wings are wedge-shaped and the forward wing edges are vertices of the wedge-shaped wings.
  • the sides of the blade may be thought of as having upper and lower portions respectively above and below the wings.
  • the first and second sides have upper portions generally located between the first and second wings and the upper surface of the blade, and lower portions generally located between the first and second wings and the lower surface of the blade.
  • the lower portions collectively form a waisted shape so that a forward width dimension of a forward flared portion of the lower portion of the opening blade and an aft width dimension of an aft flared portion of the lower portion of the opening blade, the forward and aft width dimensions extending between the lower portions of the first and second sides, are greater than an intermediate width dimension of a waisted portion longitudinally extending contiguously between the forward and aft flared portions.
  • the first wing may be defined as being set back a first longitudinal distance from the leading edge and the second wing as being set back a second longitudinal distance from the leading edge.
  • the first longitudinal distance may be greater than the second longitudinal distance.
  • the first wing mounted to the first side of the blade at a first longitudinal location generally corresponding to the aft flared portion of the blade, and the second wing may be mounted to the second side at a second longitudinal location generally corresponding to the waisted portion of the' blade.
  • an upper wing surface on the first and second wings extends aft over the corresponding first and second aft-opening wing apertures on aft cantilevered upper wing members.
  • the lower wing surface on the first and second wings may form a first wedge angle of approximately 5° with the upper wing surface.
  • laterally outer-most wing surfaces extend between the upper and lower wing surfaces.
  • the outer-most wing surfaces may advantageously intersect the corresponding first and second sides of the blade at their corresponding first and second forward wing edges. Further, the outer-most wing surfaces may form a second wedge angle of approximately 5° relative to the first and second sides of the blade respectively.
  • first and second wings may themselves also be inclined downwardly so that a pair of corresponding planes bisecting the wedge angle between the upper and lower wing surfaces on each of the first and second wings, where the pair of corresponding planes contain the corresponding forward wing edges, are inclined forwardly and downwardly at approximately 5° relative to a generally horizontal plane containing the lower surface, it being taken for the sake of this defined relationship that the lower surface is generally planar and horizontal, although this is not intended to be limiting, and is not necessarily so, notwithstanding that the preferred embodiment hereinafter described is illustrated as such.

  • Figure 8 follows on as a time-elapsed view of the view of Figure 7, illustrating the collapse of the soil and lateral translation of the seeds following the initial phase.
  • opening blade 10 has an upper, ported, mounting block 12 rigidly mounted atop a generally planar blade structure 14.
  • Blade structure 14 has a trunk 16 depending generally vertically beneath the upper ported mounting block 12. Formed as part of the lower end of trunk 16 is a foot structure generally indicated by numeral 18.
  • mounting block 12 and blade 14, including trunk 16 and foot 18, are elongate in a generally vertical plane including longitudinal axis A.
  • the outer surface of trunk 16 smoothly merges into, so as to truncate in cross-section as, a waisted or luge shaped foot lower surface 24.
  • access panels 26 and 28, which conformally mount onto the lateral side walls of trunk 16, are symmetrically shaped relative to the plane of symmetry of trunk 16.
  • Upper ported mounting block 12 has ports 30, 32 and 34 formed in its upper surface. The ports extend downwardly through block 12 in cooperative alignment with corresponding conduits or channels 36, 38 and 40 extending downwardly in generally parallel spaced apart array through trunk 16. Channel 40 also extends downwardly through foot 18.
  • 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.
  • Access panels 26 and 28 may be mounted onto trunk 16 by means of tab 48 on access panel 26 slidably engaging corresponding slot 50 in trunk 16, formed in the lower surface defining cavity 46, so as to protrude downwardly into foot 18.
  • tab 52 slidably engages slot 50 when mounting access panel 28 onto the starboard side of trunk 16.
  • the upper ends of access panels 26 and 28 may be secured by releasable fasteners for example a cooperating, flush-mounted nut and bolt pair 56 or the like.
  • channels 36 and 38 form a pair of chutes in cooperative alignment between ports 30 and 32 in mounting block 12 and corresponding lower outlet ports 58 and 60.
  • Lower outlet ports 58 and 60 are directed laterally oppositely and open into the respective interior ducts 62 and 64 formed within respective wings 20 and 22.
  • Interior ducts 62 and 64 open out into corresponding aft-facing apertures from under their respective wings 20 and 22 as better hereinafter described.
  • Toe 66 which may be of a different and hardened material relative to the material forming mounting block 12, trunk 16 and foot 18, is rigidly mounted, by bolting or other means known in the art, to the forward portion of foot 18 so as to form a forwardly extending point or snout 68, forwardly facing in the direction of forward translation B when the blade is translated in use.
  • mounting block 12, trunk 16 and foot 18 may be made of austempered ductile iron (ADI) and toe 66 may be made of a chrome alloy.
  • Access panels 26 and 28 and wings 20 and 22 may also be made of ADI.
  • Channel 40 is formed within and along the rear or aft edge of trunk 16 and foot
  • channels 36, 38 and 40 are generally parallel so as to be raked aft in a downward direction from ports 30, 32 and 34..
  • Wings 20 and 22 are each shaped as truncated wedges or otherwise as what may be described as irregular pyramid shapes wherein the vertex of each wedge or pyramid is aligned so as to be forward facing (in direction B) with the wedge diverging aft so as to form correspondingly shaped interior ducts 62 and 64 opening aft through the base of the wedges.
  • the acute angles alpha ( )and beta ( ⁇ ), formed at the vertex of the wedges forming wings 20 and 22 are approximately 5 degrees.
  • upper surfaces 20a and 22a, lateral surfaces 20b and 22b, and lower surfaces 20c and 22c of wings 20 and 22 respectively are each generally planar.
  • the upper surfaces 20a and 22a are inclined forwardly slightly downwardly relative to the plane containing foot lower surface 24 advantageously at an angle of approximately 5°.
  • 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 them contiguously aft from the rear edge of lateral side walls 20b and 22b respectively to blend with foot 18.
  • foot 18 is curvaceously waisted along its longitudinal length so as to form between curved side walls a forward expanded lateral dimension 72 smoothly tapering into a reduced lateral dimension 74 corresponding to the waisting and, progressing aft, a gentle flaring to an aft expanded lateral dimension 76.
  • the waist of foot 18 approximately corresponds in the longitudinal direction of axis A to the position of the forward ends of wings 20 and 22.
  • blade 16 is translated in direction B through soil 78 as seen in Figure 6.
  • Blade 16 is driven forwardly and positioned so as to maintain wings 20 and 22 submerged at a shallow depth below the surface of soil 78. Such motion opens the soil from point 68 upwardly along the leading edge of foot 18 and blade 16 causing a small lifting and separating of soil 78 in opposite directions C. As blade 16 translates through the soil, material fed into ports 30, 32 and 34 flows under the force of gravity through respective channels 36, 38 and 40. Material flowing through channel 40 exits through aperture 70 at the lowermost position of the narrow furrow 80 formed in soil 78 by the passing of blade 14 therethrough. The passing of wings 20 and 22 through soil 78 form shelves 82 in the soil as the soil is displaced by the wings so as to form shoulders 84 approximated in the illustration of Figure 7.
  • 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.
  • blade structure 14 is generally bisected by a first plane, referred to above as the plane of symmetry of trunk 16, which contains the cross-sectional view reference line 2-2 seen in Figure 1.
  • the cross-sectional view of Figure 2 is a view through a cutaway along that first plane.
  • a second plane E is the plane containing the edges of aperture 70 at the lowermost end of channel 40.
  • a third plane F is the plane containing foot lower surface 24.
  • a fourth plane G is the plane containing the upper surface of mounting block 12.

Abstract

L'invention porte sur un dispositif sub-surfaciel d'ensemencement, d'engraissage et arrosage, comportant une lame (14) fendeuse présentant deux côtés sensiblement symétriques s'étendant entre le bord avant (68) et le bord arrière (16) de la lame (14). Ladite lame (14) se fixe à un distributeur de matériaux en position quasi verticale de manière à être partiellement enfouie à une première profondeur dans la terre lors de sa progression bord avant en tête. Une première aile (20) et une deuxième (22), en porte à faux vers l'extérieur, sont respectivement montées du premier côté (26) et du deuxième (28). La première (20) et la deuxième (22) aile s'étendent entre leur bord avant respectif et leur orifice arrière (62, 64) respectif. La lame fendeuse (14) est traversée par un premier (36) et un deuxième (38) conduit s'étendant depuis et coopérant avec un premier (30) et un deuxième (32) orifice d'alimentation disposés à leur partie supérieure et s'ouvrant dans la surface supérieure. Le premier conduit (36) et le deuxième (38) coopèrent avec un premier (58) et un deuxième (60) canal traversant les ailes (20, 22), disposés à leur partie inférieure et s'étendant vers l'arrière entre l'extrémité inférieure de leur conduit (36, 38) respectif et l'orifice arrière (62, 64) respectif des ailes. Le premier (36) et le deuxième (38) conduit, et les canaux (58, 60) correspondants des ailes, établissent donc entre les orifices (30, 32) d'alimentation et les orifices arrière (62, 64) des ailes une communication permettant l'écoulement des graines, de l'engrais ou du fluide provenant du distributeur de matériaux, pendant la progression vers l'avant.
