Definitions

  • TITLE "GROUND WORKING TOOL" FIELD OF THE INVENTION relates to a ground working tool which most particularly but not exclusively is a “boot” which is attached to agricultural machines such as cultivators and the like
  • a conventional boot was formed of heavy gauge steel and included a socket part which included a pair of opposed attachment apertures for receiving an attachment bolt for attachment to the ripper tyne.
  • a cultivator incorporated a plurality of spaced ripper tynes which were mounted to a horizontal mounting beam which could be raised or lowered by a pair of upper and lower hydraulic ram assemblies attached to a body or chassis of the cultivator which pair of hydraulic ram assemblies were located at each end of the mounting beam.
  • the horizontal mounting beam was usually attached to the body or chassis by a parallelogram linkage. The arrangement was such that the angle of the ripper tynes to the horizontal or ground surface could be varied depending upon the hardness of the ground Normally the usual operational angle to the ground surface utilised by the plurality of ripper tynes was 45°C.
  • the conventional boot normally had a body which was substantially rectangular in cross-section which tapered inwardly from top to bottom though the socket part before forming a ground engagement spike or tapered end portion.
  • a plurality of spaced boots which were each attached to an associated ripper tyne, created a groove or furrow of loose overburden after one longitudinal pass was made by the cultivator through a tract of ground or land
  • the cultivator subsequently usually made a series of transverse passes across the longitudinal furrow, alternatively known as "cross ripping", to widen the initial groove which was usually necessary when it was desired to remove soil from a particular location such as the formation of contour banks
  • the process of "cross ripping" was time consuming and expensive especially when it was necessary to take into account the costs of fuel and tractor hire if applicable
  • the process of "cross ripping” also could not be carried out in soft or wet soil and was most appropriate for cultivating hard or rocky soil
  • the invention therefore provides, in one aspect a ground working tool which includes - (i) a body,
  • the invention in another aspect, provides a wing for a ground working tool which is attachable to the ground working tool having a terminal ground contacting projection at a free end thereof in use
  • the body of the ground working tool may have any suitable shape having a mounting part of any suitable design
  • the body is similar to a conventional boot as described above having a mounting part in the form of a mounting socket and a ground engagement part in the form of a spike or tapered end portion
  • the mounting socket may have an open end and adjacent internal socket which may have any suitable cross-sectional shape such as round or more preferably is rectangular
  • the mounting socket may have a progressive inward taper from the open end to the ground engagement part
  • the mounting part may have a pair of opposed attachment apertures to accommodate a mounting bolt and thus need not include an open end or form a mounting socket of the type discussed above
  • Each wing is preferably welded to the body but this does not preclude other forms of releasable attachment thereto However it is preferred that each wing is fixedly attached to the body
  • Each wing may include an attachment end and a free end having the terminal ground contacting projection
  • the projection is in the form of a pin of substantially round cross-section which may be welded to the free end of the wing so that the pin has a longitudinal axis which is normal to the longitudinal axis of the body but spaced from the body
  • the pin may have any other suitable cross-sectional shape
  • each wing has a substantially triangular body part of plate-like form but this is not essential and the body part may be of any other suitable shape BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG 1 is a perspective view of part of an agricultural cultivator tractor having a plurality of ripper tynes to which are attached the ground working tool of the invention
  • FIG 2 is a perspective view of the ground working tool shown in FIG 1

  • FIG 5 represents a plan view of a ground working tool constructed in accordance with a different embodiment to that shown in FIG 1 ,
  • FIG 6 represents a perspective view of the ground working tool shown in FIG 5,
  • FIG 7 represents a cross-sectional profile of the ground working tool of FIG 6 as indicated by the arrow
  • FIG 8 represents a cross-sectional profile of the ground working tool of FIG 6 as indicated
  • FIG 9 refers to a perspective view of a ground working tool constructed in accordance with a different embodiment to that shown in FIG 1 or FIG 5, and
  • FIG 10 illustrates a detailed view of the terminal ground contacting projection illustrated in FIG 9 DETAILED DESCRIPTION
  • FIG 1 there is shown agricultural tractor or cultivator 10 having a mounting beam 11 to which are releasably attached thereto a plurality of ripper tynes 12 Each tyne 12 has a multiplicity of mounting apertures 13 through which may pass a mounting bolt 14 There are also shown links 15 attached to extensions 16 of mounting beam 1 1 at 17
  • Links 15 are also attached to chassis 18 of tractor 10 at 19 and form part of a parallelogram linkage system (not shown) There are also utilised hydraulic ram assemblies attached to each end of mounting beam 1 1 which have also been omitted for convenience
  • the tractor 10 also includes crawler tracks 20 and wheels 21
  • Mounting beam 11 also includes linkage attachment lugs 22 and associated links 22A
  • Each ripper tyne 12 also includes a boot 23 attached thereto As shown in FIG 2, each boot 23 includes a body 24 having a socket part or attachment end 25, a pair of opposed attachment apertures 26 which are included in internal socket 27 tapered digging point 28 reinforcement rib 29, wings 30 which are each welded to body 24 at 31 and round pins or projections 32 which are each welded to an adjacent free end 33 of wings 30
  • Each wing 30 includes a triangular body part 34
  • Each pro j ection 30 is spaced from body 24 by space or gap 35
  • Each pro j ection 32 has an axis which is substantially normal to the longitudinal
  • each wing 30 may include an attachment edge 36 which is to be welded to body 24, free edges 37 and 38 and projection 30 welded to adjacent edge 39
  • the "free end" 33 may include edge 39, edge 38 or part of edge 37 as is considered appropriate However, preferably the projection 30 is welded to edge 39 and has an outwardly extending part 40 from body 34
  • the projection 30 may also be aligned at any suitable angle to the longitudinal axis of body 24 While the preferred angle of inclination is 90°, this may also form within the range of 45°-135" wherein the relevant angle of interest is the included angle between axis 41 of projection 30 and longitudinal axis 42 of body 24
  • the ripper tyne 12 also includes body 43, opposed recesses 44, and end projection 45 for engagement with socket 27 There is also included attachment aperture 46 which is aligned with opposed apertures 26 Mounting bolt 47 is also shown There is also shown end lug 48 having aperture 49
  • FIG 4 also shows that it is preferred that the body part 34 of each wing 30 is offset relative to the longitudinal axis of boot 23 This is shown in FIG 4 wherein a line formed by edges 37 and 38 is offset at an angle ⁇ to longitudinal axis 42 of body 24
  • ⁇ is preferably a maximum of 5° and more suitably is 1 -3° and most suitably is 2°
  • the ground working tool 23A includes body 24A, wing 30 welded to body 24A at 50, reinforcement rib 29A and a pair of reinforcement ribs 51 located adjacent to reinforcement rib 29A. There is also included a nose portion 52 of relatively shallow rectangular cross section as shown in FIG 7
  • reinforcement ribs 51 The purpose of reinforcement ribs 51 is to greatly strengthen the body 24A and thus provide body 24A with an apparently longevity which is considerably superior to conventional ground working tools or tynes
  • FIGS. 9-10 show a ground working tool 53 having body 54, tapered digging points 55, reinforcement rib 56, wings 57, terminal ground contacting projections 58 and rotatable components 59 of projections 58
  • each rotatable component 59 is mounted on a support bolt 60 having a head 61.
  • Bolt 60 may be inserted into co-aligned passages 64 and 65 of component 59 and projection 58 respectively
  • the assembly of (i) component 59 which is fixedly mounted to bolt 60, (li) bolt 60, (iii) head 61 and nut 62 may rotate as one or in unison relative to projection 58
  • the provision of rotatable component 59 means that during use of the ground working tool 53, the available surface area of component 59 is considerably increased since rotation of component 59 is caused by contact with the ground in use and thus operational longevity of the tool
  • Head 61 of bolt 60 is welded to component 59 at 66 and projection 58 is welded to wing 57 at 67
  • reinforcement rib 68 There is also included reinforcement rib 68.
  • rotatable component 59 may be rotatably mounted to a fixed bolt or pin (not shown) which is welded or fixedly attached to projection 58.
  • the ground working tool may be used satisfactorily in soft or wet terrain and that a furrow may be formed on one pass by tractor over ground requiring soil removal without there being any need for "cross ripping" or making transverse passes across the furrow which is necessary if the boot is utilised without the wings
  • the furrow formed by the ground working tool of the invention may also make a much wider furrow than in the case if the boot was used alone with the projection contacting each edge of the furrow.
  • the wider furrow thus created provides a furrow far more suitable for the retention of water than in the case of a narrow furrow with steeply sloping sides formed by the boot alone This means that the wider furrow is superior when compared to the narrow furrow for planting purposes This means that plants have a far greater chance of germinating and thus use of the ground working tool of the invention provides a superior seed bed than in the case of the narrow furrow
  • the ground working tool of the invention may be utilized for soil removal or for cultivation In the case of soil removal, the requirement for "cross ripping" is now substantially overcome
  • a field may be rapidly ploughed or cultivated by making a first series of parallel passes in one direction and making a second series of passes intermediate adjacent passes of the first series in a second direction
  • soil will pass underneath outwardly extending part 40 or rotatable component 59 and thereby compacts the soil along the opposed sides of the furrow thus formed This has a desirable effect of stabilizing each side of the furrow
  • the presence of each gap 35 also provides clearance so that bolts 47 may be removed from opposed apertures 27 when desired
