Description

Technical field The present disclosure relates to a point for a soil working tool for use on an agricultural implement to cut off roots of plants, in particular in connection with the combating of weeds, and to an agricultural implement comprising a plurality of soil working tools having such points.

Such soil working tools may be referred to as "cultivating tools , weeding tools" or, due to their appearance, "goose foot tools". The tools may be used for weeding continuously across the entire width of the implement, or for so-called "row-cultivation", wherein weeding is achieved between rows of a crop.

The disclosure further provides a method of manufacturing such a point.

Background The use of cultivating tools is particularly interesting as it provides a way of reducing or eliminating the use of herbicides to combat weeds, either over an entire field, or in between rows of a crop, i.e. in "row cultivation".

Such cultivating tools are known from e.g. WO2022/098287A1.

When designing a tool for cultivating, it is desirable to provide a tool which slides easily through the soil, thus requiring as little energy as possible, has a long working life and is effective in chopping off roots, while the risk of roots and other debris being accumulated by the tool, without being chopped off, is reduced as much as possible.

Further cultivating tools are known from e.g. USD480734, EP1397949, US7770657, EP3046407A1.

There is still a need for further improved cultivating tools for combating weeds, and in particular tools which combine a low energy consumption with effectiveness in combating the weeds and with a long working life ofthe tool.

Summary An objective of the present disclosure is to provide an improved tool for soil cultivation, and in particular an improved row cultivating tool.

The invention is defined by the appended independent claims, with embodiments being set forth in the appended dependent claims, in the following description and in the attached drawings.

According to a first aspect, there is provided a point for a soil-working tool for an agricultural implement, the point having a predetermined working direction and a predetermined working orientation, the point comprising a point body with a pair of opposite and laterally extending wing portions, the point body having a front portion having a leading edge portion and a pair of generally forwardly facing first edge portions, the first edge portions provided on a respective one of the wing portions, and a rear portion, having a pair of generally forwardly facing second edge portions, the second edge portions provided on a respective one of the wing portions, wherein each of the first edge portions extends rearwardly and laterally outwardly from the leading edge portion, when the point is in the predetermined working orientation, wherein each ofthe second edge portions extends laterally outwardly from a rearmost part of one of the respective first edge portions, when the point is in the predetermined working orientation, and wherein, as seen in a projection on a horizontal plane when the point is in the working orientation, each of the first edge portions presents a first cutting edge, which is straight and extends at a first angle of about 150-170 degs, preferably about 158-162 degs, to the working direction. Each of the second edge portions presents a second cutting edge extending at a second angle to the working direction, which is smaller than the first angle by at least 15 degs, preferably 20 degs or 25 degs.

A point for a soil-working tool is defined as a component that is intended to be releasably attached to a holder or ca rrier that may have the form of a tine or a pin. Typically the point will constitute a wear part and outermost part of the soil working tool, and be arranged at a free end of the soil working tool.

A working direction is defined as the direction along which the soil working tool carrying the point will be drawn through the soil when the agricultural implement moves along a straight line. Hence, on a horizontal and level soil, the working direction will be a direction in the horizontal plane.

A "working orientation" is defined as the orientation of the point when the it is drawn through soil during normal operation along the working direction.

The first and second angles to the working direction are defined as an angle in a clockwise direction for the right side ofthe point, as seen in the working direction and in a counter clockwise direction for the left side of the point.

The first cutting edge being straight is understood as the first cutting edge being straight over at least 90 % of its length, and preferably continuously straight over at least 90 % of its length. lt is understood that manufacturing necessitates a small transition radius between the first and second cutting edges. Hence, the second angle may be taken at a point that is at a lateral horizontal distance of about 1-10 mm, about 2.5-7.5 mm or about 5 mm, outside of a laterally outermost point where the first cutting edge ceases being straight.

By providing such second angle, a more abrupt transition is provided between the first and second edge portions, such that the chance of roots being chopped off, rather than just bent, by the second edge portion is increased.

The second angle may be greater than 90 degs to the working direction.

The second angle may be about 90 degrees to the working direction.

The second angle may be smaller than 90 degrees to the working direction.

The second cutting edges may be substantially straight.

The second cutting edges may be forwardly convex. ln this embodiment, the second angle may be taken between the first edge portion and a tangent of the second edge portion near the first edge portion.

I\/|oreover, a curved edge portion may be approximated by an edge portion comprising a plurality of partial edge portions. For example, each such partial edge portion may extend on the order of about 5-30 % ofthe length of the entire edge portion.

The leading edge portion may be at least partially formed from a material having greater abrasion resistance than the point body.

According to a second aspect, there is provided a point for a soil-working tool for an agricultural implement, the point having a predetermined working direction and a predetermined working orientation, the point comprising a point body with a pair of opposite and laterally extending wing portions, the point body having a front portion having a leading edge portion and a pair of generally forwardly facing first edge portions, the first edge portions provided on a respective one of the wing portions, and a rear portion, having a pair of generally forwardly facing second edge portions, the second edge portions provided on a respective one of the wing portions, wherein each of the first edge portions extends rearwardly and laterally outwardly from the leading edge portion, when the point is in the predetermined working orientation, wherein each ofthe second edge portions extends laterally outwardly from a rearmost part of one of the first edge portions, when the point is in the predetermined working orientation, wherein, as seen in a projection on a horizontal plane when the point is in the working orientation, each of the first edge portions presents a first cutting edge extending at a first angle to the working direction, and wherein each of the second edge portions presents a second cutting edge extending at a second angle to the working direction, which is smaller than the first angle. The leading edge portion is formed from a material having greater abrasion resistance than the point body.

The leading edge portion may have a leading edge, which extends substantially horizontally and/or perpendicular to the working direction, when the point is in the predetermined working orientation.

The leading edge portion may have a width that is about 5-15 % of a total width of the point.

The first edge portions may be at least partially formed from a material having greater abrasion resistance than the point body.

The second edge portions may be at least partially formed from a material having greater abrasion resistance than the point body.

Each wing may present a tapering portion situated laterally outside of a mounting portion, which tapering portion, in a direction perpendicular to the working direction and along a distance of at least 25 % of a total maximum width of the point body, presents an outwardly continuously diminishing material thickness.

A point with such varying thickness provides for an improved distribution of the material from which the point is formed, in that a greater thickness is provided near the center of the point body and a smaller thickness is provided nearer the wing points.

According to a third aspect, there is provided an agricultural implement comprising an implement frame to be carried and/or pulled by a traction vehicle, and a plurality of soil working tools, supported by the implement frame, and distributed over a width ofthe implement frame, wherein at least some of the soil working tools are provided with a point described above.

According to a fourth aspect, there is provided a method of manufacturing a point for an agricultural implement as claimed in any one ofthe preceding claims, the method comprising providing a blank having a blank body of a thickness that is about 100-150 % of a final thickness of a point body, heating the blank body to a temperature that is about 60-80 % in Kelvin of a melting temperature ofthe blank, forming the heated blank body into the point body by pressing the heated blank between a set of dies, such that a cutting portion and a mounting portion of the point are formed in one piece from the blank body.

The method may comprise attaching at least one piece of, or coating the point body with, a material having greater abrasion resistance than the point body so as to form part of at least one of the leading edge portion, at least one of the first edge portions and/or at least one ofthe second edge portions.

The cutting portion 1011 further comprises a pair of wing portions 102a, 102b, extending laterally from a central horizontal axis C of the point that is parallel with the working direction Dw.

The wing portions 102a, 102b may comprise a pair of first side edge portions 104a, 104b, which extend rearwardly from the leading edge 1031 and which provide a respective first side cutting edge 1041a, 1041b.

The first side cutting edges 1041a, 1041b may, as seen in the horizontal plane, be substantially straight and extend at a respective first angle A1 to the working direction Dw. Hence the first side edge portions 104a, 104b may together form an essentially delta-shaped portion of the point body 101.

At a rearmost portion of the respective first side edge portion 104a, 104b, the first side cutting edges 1041a, 1041b transition into a respective second side cutting edge 1051a, 1051b, which form part of a respective second side edge portion 105a, 105b.

Optionally, a first release portion 108 may be arranged on upper side of point body, rearWardly of the front portion 103 and centrally as seen in the |atera| direction. This release portion may be provided in the form of a doWnWard recess or valley immediately behind the front portion.

Optionally, a second release portion 109 may be arranged at an underside of a rear portion of the respective Wing portion 102a, 102b. ln some embodiments, the Wing portions 102a, 102b may thus be curved slightly upWardly at rearmost and outermost portions thereof. ln other embodiments, the Wing portions 102a, 102b may taper at rearmost and outermost portions thereof, such that a release portion is provided at a loWer and/or upper part of the respective Wing portion 102a, 102b.

The Wing portions may further taper in a direction from the symmetry plane and laterally, in particular perpendicularly, outWardly, to present a diminishing material thickness, assuming that the point is positioned on a horizontal surface and the thickness direction is parallel With a vertical direction.

Such tapering portions may be situated laterally outside of the mounting portion and laterally inside of the second edge portions.

The tapering portions may have a length Which is at least about 25 % of a total maximum Width of the point, preferably at least about 30 % or at least about 35 %.

A point (10) for a soil-working tool for an agricultural implement, the point having a predetermined working direction (Dw) and a predetermined working orientation, the point comprising: a point body (101) with a pair of opposite and laterally extending wing portions (102a, 102b), the point body (101) having: a front portion having a leading edge portion (103) and a pair of generally forwardly facing first edge portions (104a, 104b), the first edge portions provided on a respective one ofthe wing portions (102a, 102b), and a rear portion, having a pair of generally forwardly facing second edge portions (105a, 105b), the second edge portions provided on a respective one of the wing portions (102a, 102b), wherein each of the first edge portions (104a, 104b) extends rearwardly and laterally outwardly from the leading edge portion (103), when the point is in the predetermined working orientation, wherein each of the second edge portions (105a, 105b) extends laterally outwardly from a rearmost part of one of the first edge portions (104a, 104b), when the point is in the predetermined working orientation,wherein, as seen in a projection on a horizontal plane when the point is in the working orientation, each of the first edge portions (104a, 104b) presents a first cutting edge (1041a, 1041b) extending at a first angle (A1) to the working direction (Dw), and wherein each of the second edge portions (105a, 105b) presents a second cutting edge (1051a, 1051b) extending at a second angle (A2) to the working direction (Dw), which is smaller than the first angle (A1), characterized in that the leading edge portion (103) is formed from a material having greater abrasion resistance than the point body (101).

9. The point as claimed in any one ofthe preceding claims, wherein the leading edge portion (103) has a leading edge (1031), which extends substantially horizontally and/or perpendicular to the working direction (Dw), when the point (10) is in the predetermined working orientation.

10. The point as claimed in any one ofthe preceding claims, wherein the leading edge portion (103) has a width that is about 5-15 % of a total width of the point (10).

11. The point as claimed in any one ofthe preceding claims, wherein the first edge portions (104a, 104b) are at least partially formed from a material having greater abrasion resistance than the point body (101).

12. The point as claimed in any one ofthe preceding claims, wherein the second edge portions (105a, 105b) are at least partially formed from a material having greater abrasion resistance than the point body (101).

13. The point as claimed in any one ofthe preceding claims, wherein each wing portion presents a tapering portion situated laterally outside of a mounting portion (106), which tapering portion, in a direction perpendicular to the working direction (Dw) and along a distance of at least 25 % of a total maximum width of thepoint body (101), presents an outwardly continuously diminishing material thickness.

14. An agricultural implement comprising: an implement frame (11, 110, 111, 112) to be carried and/or pulled by a traction vehicle, and a plurality of soil working tools (15), supported by the implement frame, and distributed over a width ofthe implement frame, wherein at least some of the soil working tools are provided with a point (10) as claimed in any one ofthe preceding claims.

15. A method of manufacturing a point for an agricultural implement as claimed in any one of the preceding claims, the method comprising: providing a blank having a blank body of a thickness that is about 100-150 % of a final thickness of a point body (101), heating the blank body to a temperature that is about 60-80 % in Kelvin of a melting temperature of the blank, forming the heated blank body into the point body by pressing the heated blank between a set of dies, such that a cutting portion and a mounting portion of the point are formed in one piece from the blank body.

16. The method as claimed in claim 15, further comprising attaching at least one piece of, or coating the point body with, a material having greater abrasion resistance than the point body (101) so as to form part of at least one of the leading edge portion, at least one ofthe first edge portions and/or at least one ofthe second edge portions.
