    [0001] 1 Direct seed drill for all seeds, corn, wheat, cereals and grass, allowing to carry out work directly on unprepared land. The invention relates to a direct drill for sowing directly on unprepared sites and still having on the surface stubble of previous crops.
    [0002] Currently, the trend to reduce the time of seedling preparation to move towards direct seeding, ie without preparation of the fields by plowing and leveling. In addition, the conservation of stubble and other plant debris on the surface of the field maintains some moisture on the surface and moderates soil depletion in terms of fertilization.
    [0003] The difficulties in this type of direct seeding lie in the good positioning of the seeds in the soil, considering existing stubble on the ground or roots still in the soil and resulting from previous harvests. Another difficulty lies in the positioning at a substantially constant depth of the seeds, with respect to the surface of the soil, taking into account the irregularities of the soil and the plurality of bumps formed inter alia by the weather and the devices during harvesting of the crop. previous. To perform this type of work, the known apparatus generally comprise an opener disc to make a furrow in front of a plow that positions the seeds in the ground; the coulter is supplied in seed through a hopper placed on the upper part of the frame; the depth of the opening of the ground with the opening disc is regulated by means of a gauge wheel; and at the back of the device, a plaster wheel closes the furrow and cuts the soil to compress the seed in the latter to facilitate germination.
    [0004] Also known is the US patent BARTON PETER No. 01 432 2240, which patent comprises as indicated above an opener disc carried by a longitudinal frame, which opener disc is associated with a gauge wheel and said seeder has on the rear a cover wheel. The adjustment devices of the BARTON patent, whether it is the device for adjusting the depth of the share or the device for covering the groove, represent bulky parts whose adjustment is imprecise. The object of the present invention is to overcome the abovementioned disadvantages in that the means used to regulate the different work elements make it possible to bury seeds at a constant depth in the soil, whatever the surface defects may be. to seed. In addition, the apparatus object of the present, offers another interest in reducing the respective wheelbase of each unit of the drill, facilitating handling and reducing the load on the move. The present invention relates to a direct drill working autonomously and can be assembled in a variable number and parallel to each other, on the same transverse bar supported for a coupling, which transverse bar is pulled in the direction of advance of a tractor. For the correct understanding of the text the direct drill will have a front located at the crossbar and a back located on a side opposite to said crossbar; in the same way, to conveniently locate a right side and a left side to the direct drill or element in relation to another element, the direct drill will be seen from its rear and towards its front. The direct drill comprises a flange for the hitch which indirectly carries four pressure rods, two of which support a frame formed of a substantially vertical wall; which frame is traversed in the lower part by a lower pin which carries on the left side a handle for adjustment and on the right side, starting from the frame walls, an opening disc and an arm supporting a gauge wheel; which frame carries in the lower part a share connected to a seed hopper; and said frame extends rearwardly and carries four earth rods by ends, which earth rods support at other ends a support piece holding a cover wheel 25 by means of adjusting elements. A first adjustment of the pressure exerted by the direct drill on the ground, is carried out by means of the following elements: - with the flange fixed on the transverse bar placed at the front, which flange is extended towards the back by two wings having lateral and vertical positions; said wings bear respectively two ends of two pressure rods positioned on the same side and on two levels, which pressure rods respectively have another end facing rearwardly and towards the ground; The pressure rods are juxtaposed in pairs and on two levels; which pressure rods are interconnected at their ends with transverse axes and the articulation of said pressure rods is subject to a spring, which spring is adjustable to increase or reduce the pressure of the direct drill on the ground; The ends of the pressure rods situated towards the rear and to the left with respect to each pair, have the transverse axes which protrude on the outside facing the chassis forming extensions which are embedded in the wall of said chassis; solidarity way to carry and transmit the pressure on the direct drill. The opening depth of the groove is regulated with a combination of several elements and a participation of the frame, as is explained below. The chassis is traversed in the lower part by the lower axis rotatably mounted on said frame; which lower axis carries on the left side a handle for the adjustment of the gauge wheel. The frame carries at a lower end a plum positioned on an oblique plane; which soc is secured to the chassis and undergoes the movements of the latter.
    [0005] On the right side of the frame, the lower axle carries the opening disc through a hub allowing it to pivot freely and the lower axle also carries an arm at a lower end. The arm is positioned parallel to the opener disc and said arm is directed towards the rear of the direct drill. The arm is secured to the lower axis which supports it; in other words, when the lower axis rotates, the latter drives said arm in its rotation. The arm is provided at mid-length with a rotary shaft which supports the gauge wheel positioned a little downstream from the opener disc. Thus, when the handle is operated from one position to another, said handle rotates the arm in another position with respect to the ground and causes a displacement of the gauge wheel, resulting in reducing or increasing the depth of opening in the soil through the opener disc. The rotary axis carrying the gauge wheel being located eccentrically, relative to the positioning of the lower axis placed on the frame, is that during a manual movement of the arm, according to the direction, through the arm, the gauge wheel raises or lowers the frame relative to the ground and simultaneously the opener disc undergoes the same displacement on a vertical plane and accentuates or decreases the opening depth. The arm carries at an upper end and by means of a rod, a scraper juxtaposed around the circumference of the gauge wheel; which scraper flushes the earth adhering on said circumference during the rotation of the gauge wheel and prevents any accumulation around the gauge wheel which would distort the settings. The handle acting on the lower axis, is provided in the upper part with a sliding portion allowing through a handle to pull said handle from one position to bring it to another position; which positions are materialized by a succession of notches formed in a selector fixed in the upper part of the frame. The selector has a curved and longitudinal shape so as to be concentric with the lower axis supporting said handle. The adjustment of the pressure and the orientation of the cover wheel located at the rear of the direct drill, is carried out mainly by means of the earth rods and by means of a support piece comprising several adjustment elements combining their interactions. . The frame extends towards the rear of the direct drill and carries on both sides of its sides four connecting rods juxtaposed by pair and on two levels; the connecting rods 15 are joined with transverse axes and maintained with tubular spacers on two levels. The earth rods pivot at one end on the chassis and their other rearward-facing ends hold the support piece which is arranged adjustment means for holding and orienting the cover wheel. The support piece is mainly formed of a plate surmounted by two wings arranged in parallel; on which wings pivot the ends of the connecting rods. The ends of the earth rods are coupled in pairs by means of transverse axes and tubular spacers. The platen has a lateral overhang with respect to a wing, which lateral overhang has an aperture close to the wing, which aperture has an elongated and curved shape for one of the settings of a plate positioned under the platen; which plate has at an outside a bend oriented towards the ground which supports a fixed axis to carry and maintain the cover wheel. The pair of earth rods located at a higher level has upper edges 30 having teeth juxtaposed on the same plane, on which teeth moves a pressure element placed transversely on said upper edges of the connecting rods. The pressure element comprises at the ends and symmetrically, studs 3034954 5 to achieve its nesting on the teeth during its path by rotation on the edges of the connecting rods. The pairs of earth rods are controlled by an elastic means such as a spring exerting a downward tension, one end of the spring is fixed on a lower part of the chassis and another end of said spring is fixed on the pressure element. The adjustment of the pressure of the cover wheel is very easy, in fact, depending on whether the pressure element travels in the teeth towards the front, with the aid of a key, the spring relaxes and the pressure the lap wheel on the ground decreases; conversely, if the pressure element is brought to the rear of the direct drill, the spring is stretched and the pressure of the cover wheel on the ground increases. The following description together with the accompanying figures illustrate one embodiment by way of example and without limitation and will facilitate the understanding of the invention and other details. Figure 1 shows in elevation, a view of the direct drill left side. Figure 2 shows a right side view of the direct drill equipped with the gauge wheel. Figure 3 shows a right side view of the direct drill without the gauge wheel, to 20 see the arm supporting the latter. Figure 4 shows a detail and top view of the adjustment elements of the cover wheel. Figure 5 shows a detail view and from below of the connecting rods and the support piece for the action of ditching performed by the cover wheel.
    [0006] Fig. 6 shows a front view of the direct drill showing the inclinations of the opener disc, the gauge wheel and the cover wheel. As represented in FIGS. 1 to 6, the direct drill according to the present invention comprises from the front end to the rear end: a flange 1 positioned on a transverse bar 2, which flange 1 extends backwards by wings 3 which carry pressure rods 4,5,6,7, subject to a spring 8; the pressure rods 5 and 7 support a frame 9 formed of a substantially vertical wall; which frame 9 is traversed in the lower part by a lower pin 10 bearing on the left side a handle 11 3034954 6 and on the right side, starting from a wall of the frame 9, an opening disc 12 and an arm 13 supporting a wheel 14 gauge; which frame 9 carries in the lower part a share 15 connected in a common way to a seed hopper (not shown); said frame 9 extends rearwardly and carries four earth rods 16,17,18,19 through one end of each of them and said earth rods 16,17,18,19 have ends positioned on a support member 20 holding a cover wheel 21 by means of adjusting elements. A first adjustment of the pressure exerted by the direct drill on the ground, is carried out by means of the elements carried by the flange 1 placed on the transverse bar 2. The flange 1 is extended towards the rear by two wings 3 positioned laterally on a vertical plane, which wings 3 respectively bear two ends of the pressure rods 4, 5, 6.7 positioned on the same side and on two levels; the pressure rods 4,5,6,7 have ends facing backwards and towards the ground.
    [0007] The pressure rods 4, 5, 6, 7 are arranged in pairs and on two oblique planes and for each of the pairs, the pressure rods are secured to each other by means of a transverse partition 22. The connecting rods pressure component each pair have their ends vis-à-vis connected with transverse axes 23,24,25,26 for coupling their resistance to efforts. The articulation of the two pairs of pressure rods 4, 5, 6,7 is controlled by a spring 8 to compensate for an upward movement of the chassis caused by the pressure wheel on the ground. The spring 8 is disposed diagonally in a space defined by the proximity of the two pairs of pressure rods; said spring 8 is fixed by one of the two ends to a front spacer 27 placed around the transverse axis 23 located at the front of a pair of pressure rods and said spring 8 is fixed at its other end to a rear spacer 28 placed around the transverse axis 26 located at the rear of the other pair of pressure rod. The spring 8 comprises a helical portion and a threaded rod adjustable by means of a nut so as to graduate the pressure transmitted on the two pairs of pressure rods.
    [0008] The two pairs of pressure rods carry the chassis, through external extensions of the transverse axes 24, 26 located at the rear of the pressure rods 5.7; which transverse axes 24,26 at the ends facing the frame, are continued outside the pressure rods and are embedded in the wall of the frame 1 to maneuver and maintaining said frame 9 on a vertical plane. The frame 9 is formed mainly of a vertical wall traversed in the lower part by the lower axis 10 pivotally mounted on the frame 9, which lower axis 10 carries on the left side a handle 11 for adjusting the wheel. gauge and said frame also carries in the lower part a share 15 positioned on an oblique plane; which soc 15 is secured to the frame 9 and its depth of penetration into the ground is regulated by the movements of the frame on a vertical plane.
    [0009] The lower axis 10 carries, on the right side of the frame 9, the opening disc 12 through a hub 29 allowing it to pivot freely and said lower axis 10 carries the arm 13 by a lower end. The opener 12 is inclined (see Fig. 6) to the frame wall 9 so as to open a groove and cut off all the roots and rods in its path. The arm 13 is positioned parallel to the opening disc 12 and carries at half length a rotary axis 30 on which pivots the gauge wheel 14 having an inclination identical to that of the opener disc 12. The arm 13 is mounted on the lower axis 10 in solidarity, in other words when the lower axis 10 rotates the latter drives said arm. The arm 13 is oriented rearwardly with respect to the lower axis 10 locating the gauge wheel a little downstream of the opener disc 12. The handle 11 used to adjust the depth of the groove has in its extension in the upper part, a sliding part comprising a lower tube 32 which passes through a helical spring 34 and is continued upwards by an upper tube 31 having a larger section 25. The extension of the coil spring 34 is limited by two rings located at its ends. The upper tube 31 is provided in the upper part with a handle 33 and said upper tube 31 blocks through its section in notches 36 located in a selector 35. The upper tube 31 is posted through the selector 35 by the via a slot formed along the length of said selector 35; which selector 35 is fixed on the left wall 30 of the frame 9 and composes a concentric curve to the lower axis 10 carried by the frame. The slot of the selector 35 comprises on one side the notches 36 for locking the upper tube 31 by its section in a chosen position.
    [0010] For the adjustment of the depth of the groove, by means of the handle 33, traction is exerted upwards to dislodge the upper tube 31 of a notch 36 and to convey said upper tube 31 through said Slot to another notch 36. Thus, when the handle 11 is operated from one position to another, said handle pivots through the lower axis 10, the arm 13 and also causes in another position to the of the ground, the gauge wheel, having as a result of reducing or increasing the opening depth in the ground through the opener disc 12. The frame 9 extends towards the rear of the direct drill and door part and other side of it four earthen connecting rods 16, 17, 18, 19, juxtaposed in pairs, which earth rods are joined with pins and held with tubular spacers 37, 38 on two levels. The earthen connecting rods 16, 17, 18, 19, pivot at one end on the frame 9 and their other ends are held on a support piece 20. the support piece 20 is arranged with adjusting means for holding and orienting the wheel. recovery. The support part 20 is mainly formed of a plate 39 surmounted by two wings 40 arranged in parallel. The ends of the earthen connecting rods 16, 17, 18, 19 located towards the rear are fixed on the wings 40 and hold said support part substantially on a horizontal plane. The plate 39 has a flange 41 on the side with respect to a flange 40, which overflow 41 has an opening 42 close to the flange, which opening 42 has an elongated and curved shape for one of the adjustments of a plate 43 positioned under the plate 39. The plate 43 forms at an outer end a bend 44 oriented towards the ground and carrying a fixed axis 45 on which is held and pivots the cover wheel 21.
    [0011] The earth rods 16, 17 have rectilinear upper edges having teeth 46 on the same plane and on which teeth 46 moves a pressure member 47 placed transversely on the upper edges of said earth rods 16 and 17. L The pressure member 47 moves in a rotational movement and has at the ends and symmetrically cylindrical teeth 48 which run under manual action in the teeth 46 of the upper edges. The pressure element 47 has a longitudinal body and is held in pressure towards the ground by one of the two ends of a spring 49 and the latter at its other end fixed on a lower part of a tab 50 secured to the frame 1.
    [0012] The spring 49 is positioned by means of a ring in a groove 51 located around the periphery of the pressure element 47 and at the mid-length of the latter, so as to exert a balanced pressure on the connecting rods 16 and 17.
    [0013] The plate 43 positioned under the plate 39 has a substantially rectangular shape and has a longitudinal opening 52 on its median axis; through which longitudinal opening 52 are introduced two screws 53 and 54 positioned by the lower face of the plate 43. The screws 53 and 54 are immobilized by means of two nuts 55 and 56 placed on the plate 39 and the overhang 41, allowing the fixation and adjusting said plate 43 to plate 39 and providing an angle to the cover wheel with respect to the opening axis of the groove. The screw 53 holds the plate on a fixed point of the plate 39 through a hole in said plate and between the two wings 40; the screw 54 is placed in correspondence with the opening 42 situated in the overhang of the plate. The screw 54 being capable of being displaced in the opening 42 of the plate for adjustment of the axis of the cover wheel relative to the axis of the groove. In addition, the longitudinal opening 52 of the plate 43 allows adjustment of the distance of the cover wheel relative to the opening axis of the groove. Indeed, the plate 43 can be moved in the transverse direction 20 and relative to the support part 20, through the longitudinal opening 52. On an upper part of the plate 43, close to the cover wheel, is marked; a graduation 57 for the transverse adjustment of the positioning of said cover wheel, and an indicator finger integral with the end of the plate allows to locate the setting.
    [0014] The chassis 1 carries on the right side and facing the opener disc 12, a scraper 58 juxtaposed to one side of the opener disc to disengage the bonded earth; another scraper 59 is placed in the upper part of the arm 13 by means of a transverse rod, which scrapes 59 at a side juxtaposed around the circumference of the gauge wheel 14 so as to clear the earth and to preserve the adjustment of the depth of opening of the groove.
