Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT Application Number: Lodged: Invention Title: Construction Arrangement Applied to a Furrowing Attachment The following statement is a full description of this invention, including the best method of performing it known to :-us CONSTRUCTION ARRANGEMENT APPLIED TO A FURROWING

ATTACHMENT

FIELD OF THE INVENTION The invention relates generally furrowing attachments used in agricultural machinery and implements and more particularly to a furrowing attachment based on an assembly on the furrowing coulter that makes it possible to use this device as a fertiliser or seeder, also having a straw-cutting mechanism with interchangeable points that are mounted on the end of the coulter. This assembly provides the farmer with more options, both for planting and for fertilising, and includes various kinds of points, so the one best suited to the type of soil can be S•used.

0 BACKGROUND OF THE INVENTION The simultaneous use of land for agriculture and livestock breeding is on the increase among farmers, but this practice causes some problems, such as excessive soil compaction and the inability to cut straw efficiently due to accumulated surface moisture; this hinders ongoing planting, causing the tractor S•driver to make frequent stops for cleaning and freeing the furrowing coulter. Soil compaction makes deep fertilisation difficult, and minimum tillage planting requires fertiliser to be put at a depth of up to 15 cm, depending on the culture, so the plant's roots can grow vertically with greater vigour and resistance to long drought periods.

SUMMARY OF THE INVENTION The idea of this invention is to introduce a new concept of a furrowing machine with a straw-cutting mechanism, applicable to furrowing coulters for agricultural machinery and implements, providing more efficient cutting than conventional systems, both for minimum tillage planting as for traditional planting, resulting in effective and continuous straw-cutting without excessive tillage, with a view to protecting the soil from the sun-caused effects which tend to reduce surface moisture, and preventing its erosion.

This mechanism maintains its performance in damp and dry soils, due to its straw-cutting mechanism, which provides a cutting effect exactly at the point of contact between the coulter point (which is removable) and the disk coulter, cutting the straw that was not severed on the ground and that stuck to the disk during its turning motion. In this manner the furrowing coulter puts the fertiliser in the same line as the seed and below it, at a depth of up to (fifteen centimetres).

This furrowing assembly also includes a reversible window type mechanism by which it can be used either as a fertiliser or a seeder; it was made with a view to expanding the versatility of the assembly, thus giving the farmer more options. As can be seen in the attached drawings, there are also certain kinds of adjustment of the various types of coulter, that allow these to be set closer to the disk, according to its wear, making the furrowing assembly longer lasting.

This invention offers many advantages, the main ones being listed as follows: more efficient straw-cutting, deep fertilisation, it promotes the vertical development of plant roots for more vigour and resistance with a minimum of soil tillage; the device can be used both as a fertiliser and a seeder, the coulters can be adjusted to the disk according to its wear, without decreasing straw-cutting; etc.

DESCRIPTION OF PREFERRED EMBODIMENT In Figure 1 we see the points in detail; points 01, 02, 03 and 04 have great cutting capacity and work close to the disk, while point 05 is of the retracted coulter type. They are all attached to the coulters using hole 32.

Figure 2 shows a side view of the furrowing assembly 06 set up with point 03; we can also see adjusting screw 08 and attachment bolts 09 which fasten the coulter 10 to support 07, when there is need to correct the space between point 03 and the cutting disk 11; attachment bolts 09 should be loosened so adjusting bolt 08 can move point 03 closer to disk coulter 11; this point is attached to coulter 10 by means of elastic pins 12 set in holes 32. This adjustment mechanism applies to all assemblies 06 seen in the following figures.

Also in Figure 2 we can see in detail the end of coulter 10 which has recesses 33 for fitting point 03.

Figure 3 provides a front view of furrowing assembly 06 seen in the previous figure showing the position of point 03 regarding disk 11.

SeFigure 4 shows a side view of furrowing assembly 06 with point 02 and its position with regard to disk 11. We can also see details of recess 34 and its drilling for attachment of coulter 02.
