Description
DISC PLOUGH
The present invention relates to a plough having gangs of discs.
A disadvantage of known ploughs is that the support frames for the gangs of discs are relatively complicated and contribute a significant component of the weight and cost of the ploughs.
Another disadvantage of known ploughs is that adjustment of the angle of attack of the discs of the gangs of discs has to be carried out manually. Thus, if there is a change of terrain or soil conditions that would warrant a change of the angle of attack of the discs during the course of working a field a farmer must stop the plough and manually adjust the gangs of discs. This is generally an inconvenient and time consuming task.
An object of the present invention is to provide a plough having gangs of discs which alleviates the disadvantages described in the preceding paragraphs.
According to the present invention there is provided a plough comprising:
(a) an elongate support frame having a longitudinal axis and a draw bar at a forward end thereof;
(b) an assembly of gangs of discs coupled directly or indirectly to the frame for swinging movement between a carry position in which the gangs of discs extend
longitudinally of the frame and a plough position in which the gangs of discs extend transversely to the frame, the assembly comprising a forward gang of discs which, in the plough position, extends to one side of the longitudinal axis, a rearward gang of discs which, in the plough position, extends to the other side of the longitudinal axis, and a center gang of discs which, in the plough position, extends to both sides of the longitudinal axis;
(c) a means to link together the gangs of discs so that the gangs of discs swing together between the carry position and the plough position; and
(d) a means to swing the gangs of discs between the carry position and the plough position.
It is preferred that the plough further comprises a wheel assembly coupled to one or more of the gangs of discs.
It is preferred that the wheel assembly comprises a means to adjust the height of the gangs of discs between the carry position in which the gangs of discs are clear of the ground and the plough position in which the gangs of discs contact the ground.
It is preferred that the link means interlink the gangs of discs so that the gangs of discs on each side are oppositely inclined to the longitudinal axis and the discs
have the same angle of attack.
It is preferred that the link means comprises a pair of link arms, each link arm being pivotally connected at one end to the center gang of discs and at the other end to the forward or the rearward gangs of discs, whereby in use swinging movement of the center gang of discs between the carry position and the plough position as a conseqπience of actuation of the swinging means causes swinging movement of the forward and rearward gangs of discs between the carry position and the plough position.
t is particularly preferred that the link means maintain the forward and rearward gangs of discs parallel.
It is preferred that the swinging means comprise an hydraulic ram assembly pivotally connected to the frame and to the centre gang of discs.
In one preferred arrangement the frame comprises a longitudinal beam and the gangs of discs are pivotally mounted to the longitudinal beam.
With such an arrangement, it is preferred that the hydraulic ram assembly be pivotally coupled at one end to the longitudinal beam and at the other end to the center gang of discs.
It is preferred that the longitudinal beam comprises a pair of mounting plates/arms extending to opposite sides of the longitudinal axis of the longitudinal beam and that the forward and rearward gangs of discs be pivotally mounted to the support plates/arms so that the pivot points are spaced to opposite sides of the
longitudinal axis of the longitudinal beam.
In another preferred arrangement the frame comprises a longitudinal beam and a transverse beam fixed to the longitudinal beam and the gangs of discs are pivotally mounted to the transverse beam.
It is particularly preferred that the angle between the transverse beam and the longitudinal beam be 45 degrees or less.
ith such an arrangement it is preferred that the swinging means comprises an hydraulic ram assembly pivotally coupled at one end to the transverse beam and at the other end to the centre gang of discs.

Fig. 21 is a schematic plan view of the plough in a plough position.
The embodiment of the plough shown in Figs. 1 to 17 comprises a forward gang of discs 3, a center gang of discs 5, and a rearward gang of discs 7, each pivotally mounted to a support frame in the form of a longitudinal beam 9 having a draw bar assembly 11 at a forward end thereof, and a pair of wheel assemblies 13 coupled to the center gang of discs 5.
The gangs of discs 3, 5, 7 are preferably similar to those disclosed in Australian patent no. 552035 and therefore are not described hereinafter in detail. The disclosure in the Australian patent is incorporated herein.
The gangs of discs 3, 5, 7 are pivotally mounted to the beam 9 for swinging movement between a carry position shown in Fig. 1 in which the gangs of discs 3, 5, 7 are generally parallel to the longitudinal aais of the beam 9 and a plough position shown in Fig. 4 in which the gangs of discs 3, 5, 7 extend transversely to the
longitudinal axis of the beam 9 in a prescribed configuration to work the soil over which the plough is towed in use by a tractor or other suitable vehicle.
As can best be seen in Figs. 1 and 3, the gangs of discs 3, 5, 7 are linked by link means described hereinafter so that the gangs of discs 3, 5, 7:
(a) swing together between the carry position and the plough position; and
(b) in the plough position, the gangs of discs 3, 5, 7 on each side of the longitudinal axis X-X of the plough, which coincides with the longitudinal axis of the beam 9, are oppositely inclined to the longitudinal axis X-X and the discs have the same angle of attack α.
It is noted that, whilst in most instances it is preferred that the angle of attack α of the discs on one side of the longitudinal axis X-X be the same as that on the other side, there are also situations in which different angles of attack are required.
It is also noted that there is an infinitely variable range of values for the angle of attack α.
The link means comprises a pair of link arms 21 arranged so that each link arm 21 is pivotally connected at one end to the center gang of discs 5 and at the other end to the orward or rearward gangs of discs 3, 7.
It can readily be appreciated that the location of the pivot points of the link arms 21 and the forward and rearward gangs of discs 3, 7 is important in terms of selectively controlling the swinging movement between the carry position and the plough position. In the embodiment shown in Figs. 1 to 17, which is illustrative only of one of a number of possible geometries, the beam 9 is provided with mounting plates 23 that extend to opposite sides of the longitudinal axis X-X of the beam 9. The forward and rearward gangs of discs 3, 7 are pivotally connected to the mounting plates 23 and the pivot points of the link arms 21 are located relatively close to the pivot points of the gangs of discs 3, 7 so that, in effect, there are short lever arms between the pivot points. Furthermore, the center gang of discs 5 is provided with mounting plates 27 that extend to opposite sides of the axis of the centre gang of discs 5, and the pivot points of the link arms 21 are located on the mounting plates 27.
The plough further comprises an hydraulic ram assembly 25 pivotally connected to the beam 9 and to the center gang of discs 5 to swing the center gang of discs 5 between the carry position and the plough position. As is indicated above, in view of the linking together of the gangs of discs 3, 5, 7, such swinging movement of the center gang of discs 5 causes simultaneous swinging movement of the forward and rearward gangs of discs 3, 7.
The wheel assemblies 13 support the plough for movement over the ground surface and comprise means which are operable to adjust the height of the gangs of discs 3, 5, 7 between the carry position and the plough position. As can best be seen in Fig. 4, the wheel assemblies 13 are located towards the ends of the centre gang of discs 5.
With reference to Figs. 15 to 17, each wheel assembly 13 comprises a pair of generally parallel link arms 29 pivotally connected at one end to the center gang of discs 5 and at the other end to a generally vertically extending support plate 33. The support plate 33 is connected by means of a joint 31 at a lower end thereof to a pair of ground engaging wheels 39 interconnected by an axle 37. The joint 31 allows movement of the wheels 39 about a vertical axis. An hydraulic ram assembly 35 is pivotally connected at one end to the center gang of discs 5 and at the other end to the support plate 33. It can readily be appreciated that with such an arrangement the hydraulic ram assembly 35 is operable to raise or lower the gangs of discs 3, 5, 7. It can also readily be appreciated that the combined effect of the pivotally connected link arms 29 and the joint 31 is to provide the necessary degrees of freedom of the wheel assemblies 13 to accommodate the required movement of the plough.
It can readily be appreciated that the plough is relatively compact in the carry position shown in Fig. 1 and can be transported readily as required. A further advantage of the plough is that the beam 9 provides the sole structural support for the gangs of discs 3, 5, 7 such that the use of the beam 9 and the linking together of the gangs of discs 3, 5, 7 described above is a significantly less complicated and expensive arrangement for supporting and operating the gangs of discs than is used currently in known ploughs. A further advantage of the plough is that the linking together of the gangs of discs 3, 5, 7 allows infinite adjustment of the angle of attack of the discs during use of the plough and thus the set-up of the plough can be conveniently and easily adjusted to optimise the performance of the plough over changing soil conditions and
terrain. A further advantage of the plough is that the location of the wheel assemblies towards the ends of the centre gangs of discs 5 greatly simplifies the construction of the plough.
The embodiment of the plough shown in Figs. 18 to 21 is similar in many respect to that shown in Figs. 1 to 17 and has the advantages described in the preceding paragraphs. It is noted that in the figures like numerals denote like parts.
The principal difference between the two embodiments is that, rather than using a single beam 9 as the support frame for the gangs of discs, in the embodiment shown in Figs. 18 to 21 the support frame comprises a relatively short longitudinal beam 53 having a draw bar assembly 55 at a forward end thereof and a transverse beam 51, with the gangs of discs 3, 5, 7 pivotally mounted to the transverse beam 51.
A further difference between the two embodiments is the assembly that couples together:
(a) the gangs of discs 3, 5, 7 and the transverse beam 51, and
(b) the wheel assemblies 13 and the centre gang of discs 5.
With reference to Fig. 21, by way of example, the assembly coupling together the rearward gang of discs 7 and the transverse beam 51 comprises a shaft 57 which is welded to a moulding plate 61 on the rearward gang of discs 7 and is positioned to extend through a bore 63 in the
transverse beam 51. The assembly further comprises members 65 having frust-conical female seating surfaces which are welded to upper and lower plates of the transverse beam 51. The assembly further comprises members 67 having complementary conical male seating surfaces and central bores which allow the members 67 to be positioned on the shaft 57 to face the members 65. The assembly further comprises a nut 71 which is received on a threaded end on the shaft 57 so that the seating surfaces of the members 67 and the members 65 are in mating engagement to allow relative rotation of the rearward gang of discs .7 and the transverse beam 51 around the axis of shaft 57. It can readily be appreciated that such an arrangement is essentially self-centering and can easily be disconnected/connected as required.
Many modifications may be made to the preferred embodiment described above without departing from the spirit and scope of the present invention.
In this regard, whilst the preferred embodiments comprise link means in the forms of link arms 21, the present invention is not limited to such a construction and any suitable link means such as gears could be used.
