Definitions

  • This invention relates to an agricultural assembly.
  • the invention particularly relates, but is not limited to, an agricultural assembly having a plurality of cultivator units mounted on a toolbar; to the cultivator units; and associated equipment therefor.
  • a cultivator apparatus may be towed behind a tractor or fixed to the tractor's three-point linkage to create channels or furrows in the soil, which is followed by planting of a seed within the channel, which in turn is typically followed by a press wheel assembly to press down on the soil to cover the seed and firm down the soil to provide optimal soil conditions for germination.
  • a plurality of cultivator units are attached to a toolbar that aligns the planter units and press wheels at selected distances apart from each other and that there are a number of toolbars mounted in parallel in a frame attachable to a tractor via a tow bar or three-point linkage.
  • the maximum number of planter and press wheel assemblies are attached to the frame in total.
  • operational adjustments between each of the assemblies is not consistent because there is no form of calibration of these adjustments. This results in non-uniform seed planting and pressing and thus uneven and diminished germination
  • the cultivator units are typically operated in large and often remote field situations where additional support is limited. Because there is operational benefit to attaching as many assemblies as possible to the toolbars and frames, the ability to have one operator easily and accurately attach these assemblies is important.
  • press wheel arrangements such as trailing press wheel gangs or individual frame-mounted press wheel assemblies have been utilized, but these types of arrangements are often not suited for uneven terrain and do not track well during turns. Individual press wheel assemblies are often cumbersome to use and expensive, and space limitations on the main frame can hinder proper placement. Typically, when there is a plurality of press wheel assemblies, operational adjustments between each of the assemblies is not consistent because there is no form of calibration of these adjustments. This results in non-uniform seed planting and pressing and thus uneven and diminished germination.
  • lateral movement of the press wheel assembly is adjustable and controllable such that optimum tracking can be achieved for varying soil and operational conditions including long straight row formations or alternatively cultivation in smaller fields requiring curves or smaller radius turns.
  • This same press wheel lateral control also allows the press wheel to be stowed for folded transportation without fouling or excessive wear.
  • a pivot point typically involves a boss and lugs connected by a bolt and nut. Because of the load and vibration demands placed upon press wheel assemblies, these pivot points suffer from increased compression pressure, friction and wear during continued operations, resulting in restriction of movement when tightened.
  • Press wheel assemblies achieve the desired tamping of the soil in the seed furrow by applying specific pressures to a wide variety of size, width and shaped press wheels.
  • press wheel assembly down-pressure is achieved utilizing extension or torsion springs which are subject to fatigue and breakage adjacent to the connecting or hooked end portions. The pressure applied is also un-calibrated and the subject of guess work or trial and error by the operator.
  • the arms of press wheel assemblies have been able to be varied in length to accommodate varying operational soil and planting conditions.
  • these adjustments have been adhoc and subject to guess work by the operator.
  • the calibrated longitudinal positioning utilised in conjunction with the calibrated down load applied to the main extension arm, enable consistent, repeatable and exacting locational forces to be applied to ensure maximise planting conditions.
  • Soil can easily accumulate on and around the press wheel, especially in wet or muddy conditions, and it is necessary to continually remove these build ups to ensure continuous even pressure on the overlaying soil, and thus coverage of the seeds.
  • a variety of mud scraping methods and mechanisms have been developed, but typically they have either provided insufficient adjustment, or it has not been possible to consistently adjust the mechanism for optimal performance.
  • the invention preferably includes the ability to change or rotate the press wheel axle hub assembly such that the press wheel can be set to track in a slight offset position, either left or right of centre, such that the movement of the press wheel as it tracks through and across the soil, skews any accumulated mud or soil from the press wheel thus keeping the press wheel free of soil build up.
  • the assembly main extension arm and pivot mechanisms are designed such that when the press wheel is used in an offset position, there is suitable compensation applied and the entire main extension arm and press wheel assembly tracks longitudinally in a straight track.
  • the invention also preferably includes an easy to use, incremental and calibrated adjustment mechanism within a mud scraper assembly to allow consistent and accurate locational positioning of the mud scraper relative to the press wheel, thus ensuring the press wheel is clear of build up and the optimum performance of the mud scraper and press wheel mechanism as a whole.
  • a solid chain loop is typically dragged over the ground immediately following the press wheel.
  • the mounting bracket for the chain loop it typically positioned aft most of the press wheel, which increases the likelihood of inter-press wheel assembly fouling or clashing when there is a plurality of press wheel assemblies.
  • the lateral distance between assemblies must be increased, reducing the number of assemblies able to be mounted on each toolbar and within the cultivator in total.
  • Cutting and lateral displacement of trash, roots and stubble from the tilling or sowing path is critical to effective planting and germination of the sown seed in agriculture.
  • Typical depth drum and coulter disc assemblies are inefficient and do not adequately prepare the soil for the tilling or sowing process and allow build up of stubble and trash on the cultivator mechanism.
  • ground engagement apparatus such as depth drum and coulter disc are used to cut through the trash, roots and stubble within the soil to allow ploughing, sowing and planting mechanisms clearer and easier passage through the soil thus optimising cultivation and planting conditions.
  • the assembly unit housing the depth drum and coulter disc are typically uncalibrated and difficult to attach, manage, adjust, stow and operate.
  • the depth of the coulter disc, and thus the cut that it produces, is critical for the correct location of the planted seed and thus the germination of the seed. Whilst many of the ground engagement apparatus have some form of adjustment, the adjustment is either too coarse to allow accurate depth management, or is not calibrated or easily reproducible across the great number of apparatus attached to large agricultural machinery systems. It is therefore another preferred object of the invention to provide a leading depth drum and coulter disc assembly that follows the contours of the ground to ensure even cutting depth.
  • coulter disc and parallelogram assemblies allow for a tyne assembly to be attached to and integral to the break out mechanism, but in line with and directly aft of the coulter disc assembly.
  • the tyne assembly be able to be offset from the lateral position of the coulter disc, allowing either the primary or a secondary tyne head, or both, to be operated simultaneously thus being able to apply seed or fertiliser through either tyne laterally displaced to the coulter disc.
  • a variety of mud scraping methods and mechanisms have been developed, but typically they have either provided insufficient adjustment, or it has not been possible to consistently adjust the mechanism for optimal performance.
  • the coulter disc in moving through the soil, is subject to gradual wear. Typically this wear causes the disc to reduce in radial size. As the diameter of the disc reduces the disc's position relative to the depth drum changes. Because this relative position of the coulter disc and depth drum is significant in the correct performance of the coulter disc, lateral adjustment of the position of the coulter disc is essential. It is therefore another preferred object of this invention to provide a method of adjusting the relative position of the depth drum and coulter disc by adjustment of the coulter disc lateral position. It is also another preferred object of this invention to provide a method of adjusting the lateral position of the coulter disc that is achievable by a single operator in the field and is accurately reproducible.
  • Attachment of the parallelogram assembly to a toolbar, or connection of additional cultivation or ground engagement devices or assemblies to a parallelogram assembly is typically difficult to achieve and can prove to be impossible by a single operator in the field. Consequently, altering or adjusting toolbar assemblies, adding or removing assemblies and altering the entire toolbar and cultivator assembly layout is difficult to achieve.
  • Tyne shanks are typically not designed to minimise soil shatter which occurs as the tyne shank and seed boot pass through the soil in the process of creating the furrow and planting the seed. Tyne shanks typically cause soil shatter and clumping as their blunt leading edges are forced through soil above the sowing point which is cutting the planting furrow under the surface.
  • tyne shanks are also not designed to reduce or limit the build up of mud on the leading edge of the tyne shank as it passes through wet or moist soil or the build up of stubble on the leading edge of the tyne shank as it passes through previously cropped fields.
  • the depth of the sowing point, and thus the furrow that it produces, is critical for the correct location of the planted seed and thus the germination of the seed. Whilst many of the ground engagement apparatus have some form of adjustment, the adjustment is either too coarse to allow accurate depth management, or is not calibrated or easily reproducible across the great number of apparatus attached to large agricultural machinery systems.
  • sowing point When the sowing point is not required to be in an operational position, either when not required for use or during transportation, it is essential that the tyne and tyne shank be properly stowed to avoid damage and fouling. Typically this is accomplished by either tyne shank removal or locating the shank at the upper extremity of its range of operational movement. Typically this stowed position is a part of the standard adjustment system and is not easily located or achieved.
  • Delivery of the seed into the soil and provision of fertiliser through a gas fertilizer delivery system can occur separately or simultaneously depending upon the agricultural requirements.
  • a single ground engagement apparatus is unable to provide for both delivery methods, or if it is able to, then the additional attachments required for the gas fertiliser delivery are poorly coupled with the apparatus and are normally manually attached to the outside of the tyne shank and sowing point.
  • These additional protrusions cause increased drag and friction as the tyne shank and additional attached apparatus are dragged through the soil.
  • the extra protrusions and their attachment systems become easily worn and damaged, and tend to become loose, break off or need to be regularly replaced.
  • the components tend to move around, thus not providing the specified or optimal distance between the planted seed and the gas fertiliser delivered into the adjacent soil. Additionally, should gas fertiliser delivery items, or part thereof, break off or become worn, the gas fertiliser delivery system becomes inefficient or ineffective as well as the gas leaking to atmosphere causing loss of fertilizer from the soil and possibly causing occupational health and safety issues.
  • ground engagement apparatus such as a double disc openers with leading disc or double disc openers alone, are used to create the channels or furrows in the soil into which the seed is planted, but this type of arrangement is often not suited to some agricultural conditions encountered.
  • double disc openers are the preferred apparatus used, as they minimise soil shatter which occurs as the apparatus passes through the soil in the process of creating the furrow and planting the seed.
  • any double disc opener is a pair of angled discs that move together to cut into and thus create the required furrow in the soil. As a consequence of their passage through the soil, these angled discs are subject to a variety of loads, especially side loads. The angled discs then transfer these loads into their bearings and the housing that locates the stub axles where the disc hub and bearings are situated.
  • the axle, hub and bearing assembly is a fixed part of the entire assembly. During normal use, the bearings and stub axles are occasionally sheared off when the double disc opener assembly strikes an object in the soil with significant force, or through normal wear, tear and fatigue. Because the typical assembly is a complete unit, the entire assembly will thus require replacement when damage occurs.
  • the double disc opener typically includes an integrated seed delivery system that terminates with a seed boot that is typically located at the rear, between the two discs of the double disc opener to allow immediate and accurate seed location in the furrow made by the discs.
  • the seed boot suffers significant wear as the bottom of the seed boot passes through the soil that is displaced by the two discs. This disturbed and accelerated soil impinges on the seed boot and causes the seed boot to wear and burr resulting in inferior seed placement as the inside of the seed boot is no longer smooth thus preventing easy seed flow though the tube.
  • the seed boot is a complete assembly and needs to be entirely replaced when wear causes unacceptable or inferior planting.
  • the discs of the double disc opener are subject to normal wear as the apparatus is used in typical agricultural situations as they cut a furrow through the soil in varying conditions. Additionally, the axle stubs, hubs and bearings are subject so loads and wear in normal operations. The seed boot, as it passes through the soil and is impinged on by displaced soil during planting, is also subject to wear and tear. All of these components; the discs, stub axles, hubs, bearings and seed boots are thus subject to significant wear and tear and require removal and replacement at regular intervals. Typically it is difficult to access these items in the field, especially the pair of discs of the double disc opener, which are typically difficult to remove, either singularly or as a pair.
  • the depth of the cut of the double disc opener and the seed boot depth in the furrow produced are critical for the correct location of the planted seed and thus the germination of the seed. Whilst many of the ground engagement apparatus have some form of adjustment, the adjustment is either too coarse to allow accurate depth management, or is not calibrated or easily reproducible across the great number of apparatus attached to large agricultural machinery systems.
  • the double disc opener When the double disc opener is not required to be in an operational position, either when not required for use or during transportation, it is essential that the double disc opener assembly be properly stowed to avoid damage and fouling. Typically this is accomplished by either the double disc opener shank removal or locating the shank at the upper extremity of its range of operational movement. Typically this stowed position is a part of the standard adjustment system and is not easily located or achieved.
  • Delivery of the seed into the soil and provision of fertiliser through a gas fertilizer delivery system can occur separately or simultaneously depending upon the agricultural requirements.
  • a single ground engagement apparatus is unable to provide for both delivery methods, or if it is able to, then the additional attachments required for the gas fertiliser delivery are poorly coupled with the apparatus and are normally manually attached laterally to the outside of the double disc opener assembly.
  • These additional protrusions cause increased drag and friction on the agricultural assembly as additional attached apparatus and protrusions are dragged through the soil.
  • the extra protrusions and their attachment systems become easily worn and damaged, and tend to become loose, break off or need to be regularly replaced.

  • Figure 5 has a sectional 3D view of the adjustable pivot block (8) which is attached at one end to the hinged front mount clamp bracket (2) and at the other to a trailing arm mechanism (9).
  • the pivot block allows lateral movement about a vertical pivot (10) and vertical movement about a horizontal pivot point (11).
  • the amount of lateral movement about the vertical pivot point is controlled by locating variously sized wedges (12) onto the hinged clamp bracket.

Abstract

La présente invention porte sur un ensemble agricole. L'invention comprend une pluralité de composants ou d'ensembles pouvant être alternativement fixés à un porte-outils agricole pour constituer un ensemble ou une série d'ensembles capable de satisfaire aux exigences de l'agriculture ou des cultures avec un niveau de performance optimal. Les ensembles comprennent typiquement au moins un support d'élément de serrage à montage frontal et articulé rotatif, un bloc pivot réglable étant fixé au support d'élément de serrage. Le bloc pivot vient en prise avec plusieurs coins de réglage d'arrêt, permettant de commander le déplacement latéral de l'ensemble de bras d'extension principal et de garantir les meilleures performances dans différentes conditions de plantation. L'ensemble de bloc pivot abrite également un mécanisme de réglage destiné à la régulation spécifique d'un dispositif de mise en tension de vérin à ressort permettant de fournir une charge étalonnée sur la roue de presse et d'assurer des conditions de plantation optimales. La longueur de l'ensemble de bras d'extension principal peut aussi être réglée sur une échelle étalonnée, permettant ainsi un réglage aisé et cohérent selon les conditions d'exploitation. La roue de presse est dotée d'une capacité de type moyeu déporté qui permet à la roue de se débarrasser des éventuelles accumulations de boue ou de souillures tout en permettant à la roue de creuser un sillon droit. La roue de presse comprend un support de boucle de chaîne fixé à ladite roue et monté vers l'avant plutôt que vers l'arrière, garantissant un encrassement inter-ensembles moins important et permettant de fixer un nombre plus important d'ensembles à l'intérieur du cadre d'un cultivateur donné. La boucle de chaîne peut être rangée vers l'avant sur le support de boucle de chaîne, permettant de réduire davantage la survenue d'encrassement. L'ensemble de roue de presse comprend un dispositif de raclage de boue pouvant être réglé dans toutes les dimensions et dont l'étalonnage autorise un réglage cohérent adapté à des conditions d'exploitation spécifiques. L'ensemble tambour de profondeur, disque de coutre et parallélogramme est conçu pour creuser un sillon dans le sol ainsi que pour déposer des semences et de l'engrais dans le sillon à une profondeur optimale et à des distances relatives. Le tambour de profondeur et le disque de coutre peuvent être facilement relevés et rangés lors des opérations de type sauts de rangée ou lors des transports, et le disque ainsi que la plupart des autres composants peuvent être rapidement retirés ou remplacés sans qu'il ne soit nécessaire de démonter ou de retirer les composants principaux. Le système de manchon de déversement des semences et d'administration de gaz peut être facilement installé, et demeure à une place précise ainsi qu'à une profondeur appropriée pour correspondre à la profondeur étalonnée du fond du manchon à semences et pour que le système d'administration de gaz ne soit pas détérioré lorsqu'il est tiré à travers le sol. La dent de cultivateur ultramince est conçue pour creuser un sillon dans le sol ainsi que pour déposer des semences et de l'engrais dans le sillon à une profondeur optimale et à des distances relatives. Le dispositif peut accepter une multitude de types de dents, et notamment les types requis pour administrer simultanément un engrais gazeux. Le système d'administration d'engrais gazeux est intégré à la dent de cultivateur ultramince, au sabot de semoir ainsi qu'à la pointe de semoir, afin d'assurer une administration optimale d'engrais et de garantir une longévité optimale pour le matériel. La dent de cultivateur et le sabot de semoir sont ultraminces et peu volumineux, ce qui permet de minimiser la formation de fissures et d'agrégats dans le sol ou l'accumulation de boue et de chaume lorsque la dent de cultivateur et la pointe de semoir traversent le sol. Une dent inter-rangée comprenant une pointe de lame en forme de J et un système intégré d'administration d'engrais gazeux est conçue pour creuser un sillon dans le sol ainsi que pour déposer de l'engrais dans le sillon à une profondeur optimale et à une distance relative par rapport aux semences plantées adjacentes. Le système d'administration d'engrais gazeux est intégré à la dent de cultivateur et abrité dans la pointe de lame en forme de J, ce qui permet d'assurer une administration optimale d'engrais et de garantir une longévité optimale pour le matériel. La pointe de lame en forme de J est ultramince et peu volumineuse, ce qui permet de minimiser la formation de fissures et d'agrégats dans le sol ou l'accumulation de boue et de chaume lorsque la pointe de semoir et la dent de cultivateur traversent le sol. L'enfouisseur à double disque est conçu pour creuser un sillon dans le sol ainsi que pour déposer des semences et de l'engrais dans le sillon à une profondeur optimale et à des distances relatives. Le dispositif comprend des éléments de raclage de boue, des doubles disques, un manchon à semences et un système intégré d'administration d'engrais gazeux. Le système d'administration d'engrais gazeux est intégré au manchon à semences, afin d'assurer une administration optimale d'engrais et de garantir une longévité optimale pour le matériel. Le manchon à semences, le fond du manchon à semences, les disques, les paliers, les moyeux, la double fusée et la protection du manchon à semences peuvent tous être séparément retirés et remplacés dans le champ par un opérateur unique. La profondeur de tous les ensembles peut être précisément et facilement réglée selon une profondeur étalonnée, et l'ensemble peut être fixé contre sa butée et être ainsi facilement rangé au cours d'un transport ou lorsque l'ensemble n'est pas utilisé. Les composants critiques normalement soumis à une forte usure et exposés aux intempéries sont traités pour garantir leur longévité dans des conditions d'exploitation difficiles.
