  • the present invention relates to the installation of a fence 10, similar to that shown in FIG 1 a.
  • Strainer assemblies 12 are located at each end of a long section of fence. The main role of the strainer assembly is to be able to structurally hold the force of the strained up wires and netting of the fence. Strainer assemblies will be found at the beginning and end of the fence, anywhere there is a major change in direction or topography, as well as a sturdy structure in which to attach a gate to. In fences that range over a severe distance you will find strainer assemblies in the middle to help strengthen the fence line. An example property is shown in FIG 1 b, where five strainer assemblies 12 are positioned around the border of a paddock 16. The fences may be providing the property border next to a road 14 or may be dividing paddocks 16.
  • Intermediate posts 18 in a fence sit at regular intervals between the strainer assemblies 12, as shown in FIG 1 a.
  • the main purpose is to guide the wires 20 and netting, as well as providing a smaller amount of structural support.
  • the number of intermediate posts 18 will be determined by the distance between strainer assemblies 12, as well as a desired distance between posts.
  • the desired distance between posts will depend on its purpose and mainly the livestock type and predicted pressure it is required to hold. Whilst less posts makes for an easier and cheaper fence installation, if spacing is too large the pressure is not distributed across multiple posts and breakages are more likely to occur.
  • the three mains forms of wires used in fencing are prefabricated rolls, plain wire and barbed wire. Wires come in many different thicknesses also known as gauges and tensile strengths depending on its purpose. The spacing between wires is also important, as smaller animals will require smaller gaps. There may also be a need to integrate barbed wire or electric wire into the fence.
  • One embodiment of the present invention is directed to a system for the installation of intermediate posts 18 and wires 20 between strainer assemblies 12.
  • the present invention could also be adapted to drive in the strainer assemblies.
  • a movable platform 22 integrated into a trailer 24 is towed behind a vehicle 26, although it will be appreciated that the movable platform may be integrated directly into a vehicle.
  • the trailer may be made up of a steel bottom tray 22 and a rotary moulded exterior cover or canopy 28, made for example from polyethylene.
  • Mounted to the platform 22 is a post driver assembly.
  • the assembly comprises an upright frame 32 and a weight 33 that moves within the frame on rollers.
  • the frame 32 is pivotally mounted to the platform 22, allowing it to be lowered within the trailer canopy 28 for road transport, as shown in FIG 3a. Once on a property, the frame is pivoted into an upright orientation and locked into position, as shown in FIG 3b.
  • a post feeding assembly 34 positioned in front of the post driver frame 32 is a post feeding assembly 34, which can be pre-loaded with a plurality of intermediate posts 18, to be described further below. Both the post driver frame 32 and the post feeding assembly 34 are seated on a metal plate 36 (FIG 4).
  • a metal plate 36 Towards the front of the trailer is spindle 38 that receives wire spools 40 that are wound with wires 20. The spindle is configured to tilt sideways from the platform to allow reloading of wire spools onto the spindle.
  • FIG 5 shows the combination of the upright frame 32 together with the post feeding frame 44 and an intermediate post transfer frame 46.
  • the frame of this illustrated embodiment is constructed by welding structural steel tube (typically RHS) together to form guide rails for the moveable parts.
  • RHS structural steel tube
  • the upright frame 32 is wider than the other frame sections, enabling it to pivot downwards over the top of the other frame sections to lie flat on the trailer floor, as shown in FIG 3a.
  • Upright frame 32 also partially or fully sits over post transfer frame 46.
  • FIGs 6a through 6d show the loading of the feeding assembly 34.
  • the feeding assembly includes a conveyor that has rotating conveyor belts 48.
  • Four conveyor belts 48 are used, two upper belts being a left upper belt 48a and a right upper belt 48b and two lower belts being a left lower belt 48c and a right lower belt 48d.
  • the belts 48 rotate around sleeves 51 that are fitted to the upright frame sections 50 at the front end and stepper motors 52 mounted on pads 54 at the rear end.
  • the conveyor belts are typically made of rubber and a left and right pair work together to guide the posts 18.
  • the left belts 48a, 48c include a series of outwardly extending fingers 56 with troughs 58 in between.
  • the right belts 48b, 48d include a series of peaks 60 and troughs 62.
  • This conveyor belt profile is specifically designed to accommodate a 3-point star picket post.
  • the belts are removable so that they can be interchanged for belts specifically designed for the posts being used for a particular fence installation.
  • the conveyor belts are adjacent each other on the inside of the frame 44, with opposing troughs 58, 62 creating a void shaped to receive the star picket post.
  • Cooperative rotation of the conveyor belts transfers the posts 18 to the post driver assembly.
  • Posts 18 are introduced from the front end of the frame 44 (see FIGs 6a, 6b) and are conveyed along the conveyor (FIG 6c) to the rear end (FIG 6d).
  • the feeding assembly can be pre- loaded with posts before commencing the construction of a fence, with the stepper motors being stopped until the system is ready to be used. Loading of the posts 18 can be done via side access to the trailer, as shown in FIG 7.
  • the feeding mechanism illustrated can hold 30 posts. Flowever it will be appreciated that lengthening of the conveyor would enable the system to hold more posts.
  • the post transfer frame 46 At the end of the conveyor is the post transfer frame 46.

  • Opposing arms 66 are mounted on respective tracks, with an upper pair of arms 66a and a lower pair of arms 66b being provided to grasp the post 18 as it exits the conveyor.
  • the two arms 66a move towards each other to grasp the post 18.
  • the arms move along the track rearwardly to position it underneath the post driver (FIG 8b).
  • the post is driven into the ground (as described below) and the arms move away from each other to release the post (FIG 8c). They return to their original position (FIG 8d) by sliding forwards along the track, ready to move together again to grasp a subsequent post.
  • the post driver assembly illustrated is a weighted donger, whereby a weight 33 runs along tracks created by frame 34.

  • FOG 9a predetermined height
  • FIG 9b ground
  • the weight may need to be dropped several times to drive the post into the ground sufficiently to obtain the desired height. Whilst the initial impact may be created from dropping the weight from maximum height, subsequent drops may be from a lesser height if a smaller impact is required to achieve the desired height.
  • the weight can be moved upwards by a linear actuator for example.
  • a non-illustrated embodiment could incoproate a post driver assembly that utilises a hydraulic press or a pneumatic drive to pound the post into the ground.
  • a person skilled in the art will appreciated how these drivers can be incorporated into the system.
  • the process for installing the fence begins by positioning the rear of the trailer adjacent a strainer post 12.
  • the ends of the wires 20 are attached to the strainer post 12 at the desired heights. This may include a wire 20a close to the ground, which would be guided underneath the trailer via an underlying guide and reel.
  • each wire coil on the wire spinner could be controlled by an individual high torque stepper motor, which will both allow for the wires to be spun out at an accurate timing and distance, but also help in straining the fence at the end of the run.
  • the wire coils could rotate, tightening and tensioning the wires to a desired tension allowing for an easier straining of the fence.
  • the arms 66 grasp a post 18 from the end of the conveyor and position it in the frame 32 under the weight 33. The weight is dropped onto the top of the post and the post is driven into the ground. The trailer is then advanced again to the desired location of the next post 18 and the process is repeated. The process is continuously repeated until the trailer reaches the next strainer post 12.
  • the post driver assembly and the post feeder assembly are seated on common floor plate 36.
  • the plate 36 has the ability to be stabilised in a horizontal orientation. This is achieved by three linear actuators 70 statically connected to the moveable platform 22, with arms 72 mounted to the plate 36 via universal joints 74.

  • the actuators are controlled by stepper motors.
  • the plate 36 is therefore also capable of sideways movement by sliding on tracks using linear actuators (not shown), as represented in FIGS 1 1 a, 1 1 b. Around 500mm of lateral movement could be accommodated.
