Description

The invention relates to an agricultural machine, the chassis of which includes the

  coupling points of a three-point hitch, with which the machine can be coupled to a lifting device

three points of a tractor.

  Agricultural machines, which can be coupled in the manner indicated above, to the lifting device of a tractor are often combined, in particular in the case of working machines

  the soil with other tools, such as for example a seed drill or a chemical fertilizer spreader. For this purpose, the agricultural machine must include means for coupling the additional machine.

  d 7 With the construction / invention, an effective coupling of the additional machine is obtained because the upper coupling point is arranged on a hollow support member, connected, near the ends, to the lower coupling points of the three-way attachment 15 points, by plate-shaped supports, which extend practically vertically downwards By using practically vertical supports, which form a rigid assembly with the hollow carrier member, an effective support is obtained in a simple and inexpensive manner for

  mount the coupling means of an additional machine.

  Another aspect of the invention relates to a support in the form of

  plate, located between the upper and lower coupling points and which has one or more holes for mounting a lifting device for an agricultural machine which is sufficient for fixing and effective support.

  Other objects and characteristics of the invention will emerge from the description below, with reference to the appended drawings, which

  represent, by way of nonlimiting examples, some embodiments of the device according to the invention In these drawings:

  FIG. 1 shows in plan view an agricultural machine for working the soil, provided with a construction according to the invention.

  FIG. 2 represents a profile view of FIG. 1.

  Figure 3 shows, on a larger scale, a section along

line III-III of Figure 1.

  Figure 4 shows a section along arrow IV in Figure 3, while Figure 5 shows a section along line V-V of

figure 3.

  The device shown in the figures relates to an agricultural machine, and in particular a machine for working the soil, which is

  specially intended for the preparation of seedlings.

  The machine comprises a chassis in the form of a box 1, which extends transversely to the direction of travel A and in which repo5 feels at a mutually equal distance of 25 centimeters preferably from the shafts 2, which extend upwards and preferably in the vertical direction, working members 3 Each of the working members 3 comprises a practically horizontal support member 4, which is arranged on the end, which projects under the housing 1, of a shaft 2 and which 10 carries at its ends, two working elements 5 in the form of teeth which extend downwards Near the middle of the case on top of it are deposited coupling means constituted by a structure 6, carrying points of 'coupling 7 and 8, which form a three-point hitch 15 for coupling the machine to the three-point lifting device of a tractor The structure / comprises a carrying beam 9, which extends transversely in the direction of advancement A and is located practically horizont The beam 9 is rigid in torsion and as shown in FIG. 3 is hollow, of rectangular section and preferably square of 100 × 100 mm preferably The ends of the beam 9

are closed by plates 10.

  The longitudinal axis 9 is located parallel to a vertical plane passing through the axes of rotation of the working members 3 As shown in FIG. 1, the center of the beam 9 is practically in the vertical plane, median of the box 1 perpendicular to the longitudinal axis thereof The length of the beam 9 corresponds practically with the distance between the lower coupling points 7 of the hitch / three points The beam 9 is connected to the upper face of the chassis 1 by plates of support 11 fixed near the ends of the beam 9 Near its middle, the beam 9 carries plates 12, slightly spaced from one another and which form the point

  upper coupling 8 of the three-point linkage.

  At the front, the plates 12 are provided with two holes 13, located one behind the other, for the upper arm of the lifting device 35 at three points of a tractor Each of the plates 12, which, as shown Figure 3, are practically triangular, is provided, at its

3 2551307

  base, obviously angular, in which the top of the quadrangular beam 9 is adjusted, which is tilted around its longitudinal axis towards the front The tilting of the beam 9 is such that a line

  passing through two opposite vertices is practically horizontal.

  On their external faces, each plate 12 has two edges 14, 15 curved at right angles. The front edge 14 adjusts on the upper front face of the beam 9 and extends over the entire width of this face, while the rear edge , extends over about a third of the rear upper face of the beam 9 Said upper 10 front and rear faces of the beam 9 are provided with holes for the fixing bolts 16 of the edges 14 and 15; two bolts for edge 14 and

only one for edge 15.

  The lower coupling points / of the three-point hitch comprise a sheath-shaped part 17, constructed in two parts of substantially vertical profile 18, which, at the front and at the rear, are each provided with 'a tab 19 and 20, folded back at an angle for fixing the part 17 on the housing 1 by means of bolts 16 (Fig 5) At its upper part each part 18 is folded at right angles twice to form an edge, the two edges of the parts 18 being fixed to one another by means of bolts 16, thus constituting the sheath part 17 As shown in FIG. 3, the parts 18 are produced in such a way that the height of the part 17 decreases from front to rear. In the piece 17 is housed a pivoting arm 21, formed by two bands, located one against the other The arm 21 carries at the front a fork for the coupling of a lower arm of the lifting device to three points of a tractor Its rear end is articulated in the part 17 by means of a pin 22, inserted in a hole in the arm 21 and in one of the two holes 23, located one behind the other in the parts 18 Each of the holes 23 is made by stamping outwards so that the stamping edges 24 are wider

  as the thickness of the plate in which the part 18 is made.

  The flanges 24 form a bearing for the pin 22, on which the arm 21 is articulated. In FIG. 3 the pin 22 is put in the rear hole; when the pin 22 is disposed in the front hole 23, the arm 21 projects further outside the shaped part

scabbard 17.

  The support plates 11, which support the support beam 9 near its ends, form a connection between the upper coupling point 8 and the lower coupling points 7 of the three-point hitch Each of the plates 11 comprises a face lateral 25, substantially triangular fixed by its base, using the bolts 16, to the upper edge of the profile parts 18 of the part 17 (Fig 3 and 5) The front edge of the lateral face 25 extends obliquely towards the top as well as the rear edge which is more inclined than the front edge (Fig 3) The front edge of the face 25 is connected, along the fold line a to a front face 26 at a right angle This front face has itself a folded edge at right angles This front face itself has a folded edge at right angles along line b towards the rear The folds of faces 25 and 26 along

  lines a and b give the support plates 11 great rigidity.

  As shown in FIG. 4, the width of the front face 26 increases from the bottom upwards and said face has a substantially triangular shape. The top of the face 26 is folded forward to form a lip 27 fixed to the beam by bolts 16 and holes arranged for this purpose in said beam Along the rear edge 20 of the face 25 of the support 11, an additional plate 28 is fixed by

  its inner edge curved at right angles, by means of bolts 16.

  The width of the curved edge of the plate 28 which extends from the rear of the face 25 towards the front, is practically equal to the width of one side of the beam 9 The width of the plate 28 increases 25 as shown in FIG. 4 from the bottom upwards, so that it is of substantially triangular shape The plate 28 extends transversely to the direction of advance of the machine and has, at its top, a width, which is practically twice the width of the front face 26 At its top, the plate 28 is curved to form a lip 29 which is fixed to the beam 9 by means of holes made for this purpose in the beam 9 and bolts 16 On the inside, the plate 28 has a curved square edge, the width of which is substantially the same as that of the corresponding curved edge of the face

frontal 26.

  At the rear of the lateral face 25 as well as in the curved edge of the plate 28 fixed against said face, at the level of the beam 9 of

  even in the lower part, holes 30 are made by stamping with flanges 31, directed outwards In the holes 30, are articulated

2551307

  abutments of arms 33 and 34, directed backwards, using pins 32.

  The upper arms 34 are longer than the arms 33 to take account of the forward inclination of the rear edge of the face 25 The free ends of the arms 33 and 34 can be connected to the coupling points of a machine additional 40, which here is a seed drill. Between the rear of the housing 1 and the upper arm 34 is mounted

  an adjustment cylinder 35, to allow the lifting of the additional machine 40 by the arms 33 and 34 The rear ends of the arms 33 and 34 can also carry a coupling part provided with a three point at10 telage.

  The ends of the housing 1 are closed by substantially vertical plates 36, which extend in the direction of advance A. Each of the plates 36 is provided, near the front, with a pin 37, around which is articulated an arm 38, which extends along the plate 15 towards the rear Each arm 38 can be put and fixed near the rear of the plate 37 in several positions Between the free ends of the arms 38 is mounted to rotate freely a roller, which adjusts

  the working depth of the working elements 3.

  In the case 1, each shaft 2 of a working member / carries a gear 41 with straight teeth, the gears of the shafts of neighboring working members being engaged with each other Near the middle of the case l the shaft of a working member is extended to the inside of a gearbox 42, fixed to the housing 1 inside the enclosure, formed by the beam 9 and the supports 11 of the supporting structure 6 In the gearbox 42 the extension of the shaft 2 is engaged with a shaft 44 by means of a variable speed drive 43, which is located behind the box 42 The shaft 44 s extends in the direction of travel A and protrudes from the front of the gearbox 30 swims 42 The end of the shaft 44 which protrudes out of the gearbox, can be connected to the using a return shaft 45, to

  the tractor PTO shaft.

  The machine described above operates as follows: During operation, the machine is coupled, by means of the carrying structure 6 provided with coupling points 7 and 8, with a three-point hitch, to the three-point lifting device of a tractor, so that the assembly can be propelled in a direction in the direction of arrow A During this advancement, the respective working members 3 are driven from the PTO shaft by means of the intermediate shaft 45 and the transmission described above, so that the neighboring working members 3 rotate in opposite directions and work with their working elements 5 strips of earth at

less bordering.

  The coupling means which are described in the foregoing and which comprise the supporting structure 6, formed by the beam 9 and

  the supports 11 can be made quickly from a hollow bar and profiled plates, all the assemblies being effected by bolts 16 This avoids having to resort to expensive welding work.

  The supports 11, which are practically vertical, have a reinforced practically triangular side face 25, / at the front and at the rear, reinforced by the front face, 26 and the plate 28, which extend practically at right angles to this face 25 This face 25 15 thus reinforced provides a simplified support for the arms 33 and 34

  allowing the coupling of an additional machine, here, the seed drill 40.

  Mainly, it is the widened upward parts of the pieces 26 and 28 arranged at right angles which form an effective support both for the arms 33 and 34 as for the beam 9 which carries the upper coupling point 8 and on which during the operation

  relatively large reaction forces can be exerted.

  The rigid sheath-shaped parts 17 form a support for the lower coupling points 7, formed by the arms 21, thus

  than an effective anchor for supports 11.
