Definitions
- This invention relates to a plough. This invention also relates to a tractor when provided with the plough.
- the known ploughs comprise a soil turning mechanism and a stabilising mechanism for keeping the plough in a straight line in- a single direction during ploughing.
- the soil turning mechanism creates a sideways motion when turning over the soil, and this sideways motion is counteracted and balanced by the stabilising mechanism.
- the known landslide is generally a flat piece of metal which slides in a single direction along the inside edge of a ploughed open furrow. As the landslide slides along the inside edge of the ploughed furrow, the landslide is subjected to wear and abrasion on one side only.
- the soil turning mechanism for example a mouldboard, an inversion wheel or a disc, keeps the same position relative to the position of the landslide.
- the landslide is rigidly fixed in position with respect to the soil turning mechanism, although in some cases there may be some adjustment available on the landslide for counteracting wear or aiding the forward movement of the plough.
- a plough comprising a soil tilling means and stabilising means for maintaining direction of movement of the plough during ploughing, said stabilising means comprising a fixed landslide and said soil tilling means being pivotally movable between first and second positions, relative to the landslide such that in the first position, the tilling means is operative to displace soil in one direction away from the direction of extent of the landslide and in the second position is operative to displace soil in the opposite direction away from the direction of extent of the landslide.
- the soil tilling means comprises a rotatable tilling member which is supported for rotation by an arm which itself is pivotable about an upwardly extending axis for swinging movement between said first and second positions.
- the arm may be a vertical or a semi-vertical arm.
- the lower end of the arm may be pivotally connected to the landslide.
- the soil tilling mechanism may be otherwise mounted if desired..
- a forwardly extending pointed member is provided forwardly of the tilling means to initiate breaking and turning of the soil.
- the pointed member may be mounted on a vertically positioned leg member of a plough frame.
- the soil tilling or turning mechanism may be attached to the vertically positioned leg member.
- the soil turning mechanism may alternatively be attached ot a body part of the plough or to any other suitable and appropriate part of the plough.
- the plough of the present invention maybe arranged to be drawn behind a tractor or may be directly mounted to the tractor.
- Figure 1 shows a known plough having a mouldboard type soil turning mechanism with each mouldboard being provided with a landslide stabilising means
- Figure 2 is a diagrammatic perspective view from the rear and one side of part of a plough in accordance with the invention
- Figure 3 is a view from the front and the other side of the part of the plough shown in Figure 2;
- Figure 4 is a top plan view of the apparatus shown in Figure 3 and illustrates the reversing action of the plough.
- a plough 2 comprising a soil turning mechanism in the form of four mouldboards 4.
- the plough 2 also has a stabilising mechanism in the form of a single landslide 6 provided on each mouldboard 4, although, for purposes of convenience, only one landslide is shown in Figure 1.
- the landslides 6 are attached to respective mouldboards 4 by frogs 8.
- Each mouldboard 4 comprises a shin part 10, a wing part 12 and a point 14.
- Each mouldboard 4 is attached by a leg member 16 to a central body portion 18 of the plough 2.
- the body portion 18 is connected to an upright member 20 as show .
- the bottom two mouldboards 4 are in a ploughing position for ploughing one way along a line of ploughing.
- the position of the mouldboards 4 is reversed so that the top two mouldboards 4 shown in Figure 1 are then underneath and are available for ploughing a next subsequent line of ploughing in the reverse direction. It will thus be apparent that at any one time 50% of the available soil turning mechanism and stabilising mechanism in the plough 2 are not being used. It will also be apparent that the apparatus needed to reverse the position of the mouldboards 4 with an up and over action is complicated, time consuming and expensive.
- a plough 22 comprising a soil turning mechanism 24 and a stabilising mechanism in the form of a landslide 26.
- the landslide 26 is for keeping the plough 22 in a straight line during ploughing, regardless of whether the former is being produced on the right-hand or left-hand side of the plough.
- the landslide 26 extends in the direction of ploughing.
- the landslide 26 is fixed in position at the lower end of a vertical leg 36.
- the landslide uses the side of the open furrow to create stability.
- the landslide gives stability in both directions of ploughing, with one side of the landslide operating when ploughing with a right-hand furrow and the other side of the landslide operating when ploughing with a left-hand furrow.
- the soil turning mechanism 24 includes a tilling member disc 28 which is rotatably mounted about a vertically positioned pivotable cranked arm 30.
- the disc 28 is in the form of a soil inversion wheel having a central substantially planar portion provided with a frusto-conical rim 40. More specifically, the disc 28 rotates about a central axis 32 which extends above the landslide 26.
- the arm 30 pivots about a pivot axis 34. It will thus be appreciated that the arm 30 is pivotable and thus the disc 28 itself is pivotable to swing from the position A to the position B shown in Figure 4. In the position A the disc 28 extends to one side of a vertically positioned leg member 6 and the landslide 26. In the position B, the disc 28 extends to the other side of the leg member 36 and the landslide 26.
- the leg member 36 is provided with a forwardly extending point member 38 which is the first part of the plough to engage the soil during ploughing.
- the point member 38 forms part of the soil turning mechanism and helps to complement the action of the disc 28.
- the plough will also comprise at least one frame member connected to the upper end of the leg member 36 with support being provided for the upper end of the cranked arm 30.
- This frame member can itself be attached to, or connected to be drawn from, a tractor.
- a plurality of ploughing apparatus as shown in Figure 2 will be provided with the upper frame of each being connected to a beam extending diagonally with respect to the direction of movement of the plough during use thereof so that the individual ploughs will be in staggered formation with the earth turned from a succeeding plough being inverted into the furrow left by the immediately preceding plough.
- soil inversion wheel 28 can be replaced by another soil turning mechanism such as, for example, a conventional concave plough disc.
- the plough 22 may be such that one or more of the discs 28 or other soil turning mechanisms are used in a staggered formation.
- the shape of the arm 30 and the shape of the landslide 26 may be different to those shown.
- more than one landslide may be used, for example where there is more than one soil turning mechanism.
- the landslide 26 may become worn, although wear will usually be equal on both sides since one side of the landslide operates when ploughing one way and the other side of the landslide operates when ploughing the other way.
- the landslide 26 may be provided with wear plates (not shown) . Alternatively, the landslide 26 can simply be replaced when it is worn out.
