Definitions

  • the present invention relates to an apparatus for delivering material, and in particular to an apparatus for planting seeds and/or supplying other materials, such as fertiliser or the like, to below ground level.
  • AU2010100138 describes an inter-row tyne with J knife point and integrated gas fertilizer delivery system, which is designed to cut a furrow in the soil and to deliver fertiliser into the furrow at the optimal depth and relative distance from adjacent planted seed.
  • the gas fertiliser delivery system is integrated into the tyne shank, and enclosed by the J knife point, ensuring optimal fertiliser delivery and longevity of the equipment.
  • the J knife point is slim lined and low profile to minimise soil shatter and balling or build up of mud and stubble as the sowing point and tyne shank pass through the soil.
  • the depth of the fertiliser point can be accurately and easily adjusted to a calibrated depth and the assembly can be fixed against its hard stop for easy stowage during transportation or when not required for operational use.

  • the tip 140 is slidably mounted to the tip mounting 115, with the heel 130 engaging the tip 140 to thereby prevent movement of the tip 140 relative to the tip mounting 115.
  • the heel 130 is pivotally mounted to the heel mounting 116 so that the heel 130 can move between an open position, in which the tip 140 can be removed from the tip mounting 115, and a closed position in which the heel 130, and in particular a shoulder provided on the heel 130, engages the tip 140, thereby securing the tip 140 to the tip mounting 115.
  • the tip can therefore be easily replaced by opening the heel 130, sliding the tip 140 from the tip mounting 115 and then attaching a new tip 140, before the heel 130 is returned to the closed position.

  • a stubble guard 790 formed from a generally U-shaped body 791 can also be coupled to the boot 730, for example through the use of attachment pins, bolts, or the like, extending into the boot body 731. In use, the stubble guard 790 can overlap with the shin guard 780, thereby assisting to retain the shin guard in position. It will be appreciated that an appropriate adjustment mechanism could be used to adjust the position of the stubble guard, although alternatively by providing a stubble guard of sufficient length, this can allow the stubble guard to function regardless of the tip operating depth.
  • the opening 732 acts as a boot shank mount and can receive the tine shank body 711, with boot cavity 733 receiving the T-shaped connectors 724, allowing the boot 730 to be coupled to the tine shank 710, and the heel 720.
  • the T-shaped connectors 724 key into the boot 730 to provide additional support, and in one particular example, when the heel 720 is fastened to the tine shank 710, the boot 730 can be locked onto the tine shank 710 and heel 720, so that the tine shank 710, heel 720 and boot 730 act as a single body.
  • the boot 730 may also additionally or alternatively be held in position by a bolt inserted through an aperture 734 in the boot body 731, into a corresponding one of a number of recesses or apertures 714 provided on a trailing edge of the tine shank body 711.
  • the position of the boot 730 relative to the tine shank 710 ca be adjusted by inserting the bolt into different ones of the recesses or apertures 714, thereby allowing the relative position of the heel 720 and boot 730 to be adjusted, which in turn allows the relative depth of the heel and tip to be adjusted.
  • heel material outlets can be accommodated in the heel and connected via connecting tubes or chutes to inlets mounted in the tine shank cavity 712, thereby allowing material, fertiliser, nutrients, gypsum, or the like to be delivered via the material outlets.

  • the relative position of the heel 720 and boot 730 can be adjusted, allowing the relative depth of the tip 740 and heel material outlets to be altered.
  • the boot cavity 733 can also include one or more boot material outlets, allowing material to be delivered to a region immediately behind the tip 740.
  • the boot material outlets can be provided at different positions and/or be adjustable, allowing material to be delivered at different depths when the boot is lowered relative to the heel, as shown in Figure 7E.
  • the heel and boot material outlets can be coupled to corresponding material inlets via chutes and/or connecting tubes, allowing a combination of materials including seeds, fertilisers or the like to be delivered to different depths relative to the tip 740.
