DESCRIPTION:
BRIEF SUMMARY
This invention relates to a multiple section reversible plough which comprises a forward section which is adapted to be coupled with the rear end of a propelling vehicle, a rear section, and a wheel set which supports a rear end of said forward section and also supports a forward end of said rear section, and in which the forward and rear sections have plough beams carrying sets of reversible plough bodies.
Multiple section reversible ploughs of this type are known e.g. from GB2264216 or WO94/24842, and the plough beams of each section take-up a first position for ploughing in one direction, and then are rotated about a generally horizontal axis through about 180.degree., to take up a second ploughing position for ploughing in a reverse direction. In the first ploughing position, a lowermost one of each pair of reversible plough bodies engages the ground, but upon plough body reversal, by rotation of each plough beam through approximately 180.degree., what was previously the uppermost plough body of each pair is now moved to a lowermost position, for ploughing in the reverse direction.
The reversal of plough bodies of a multi-section reversible plough will be well known to those of ordinary skill in the art, and need not be described in more detail herein.
The wheel set which supports the rear end of the forward section, and also the forward end of the rear section, may be incorporated in an intermediate plough frame section, which is located between, and which interconnects the forward and rear sections. The intermediate section may have its own set of reversible plough bodies, but more usually the intermediate section forms a relatively short length rearward prolongation of the forward plough section, and without any plough bodies.
It is known to provide a transverse pivot axis i.e. a substantially horizontal axis when the plough is on level ground, and which extends generally perpendicular to the direction of forward travel of the multiple section combination, and in which this transverse pivot axis is located between the rear end of the intermediate section and the forward end of the rear section, and which allows pivotal inclination of the rear section to be adjusted about this axis to suit requirements.
In a semi-mounted reversible plough, it is usual to provide a headstock at the forward end of the forward section, and which forms part of the fixed structure of the plough frame to be coupled with the usual three-point linkage at the rear of a tractor, and to provide a means whereby the plough beam of the forward section can pivot through approximately 180.degree. relative to the headstock at the forward end of the plough beam in order to reverse the plough bodies.
It is also known to provide an arrangement whereby the plough beam of the rear section can rotate through approximately 180.degree. relative to its mounting on the rear end of the intermediate section, in order to reverse its plough bodies.
The invention is concerned with a novel arrangement of a wheel-set supporting portion of a multiple section reversible plough, in which this new arrangement provides an improved means of adjusting the rear section simultaneously with adjustment of the forward section.
A reversible plough according to the invention is defined in claim 1.
Preferred aspects of the invention are set out in claims 2 to 10.
A preferred embodiment of multiple section reversible plough according to the invention will now be described in detail, by way of example only, with reference to the accompanying drawings, in which:
FIG. 1 is a perspective view, from the non-ploughing side, of a multiple section semi-mounted reversible plough according to the invention;
FIG. 1A is a detail view, to an enlarged scale, showing a pivot coupling at the rear end of a forward section of the plough and which permits pivotal adjustment of the forward section for plough body reversal;
FIG. 1B is a detail view, to an enlarged scale, of a pivot coupling at the forward end of the forward section for plough body reversal, and also showing means for la
