    DESCRIPTION
    OPENING DEVICE FOR THE DIRECT CEREAL SEEDING, OF THE MONODISCO TYPE WITH DEVENTED ANGLE, WITH DEPTH CONTROL WHEEL PLACED TO THE DISC SECTOR OF THE TECHNIQUE:
    The field of application of the present invention has as a frame of reference the technical sector of the industry whose main activity is the manufacture of agricultural machinery; and, more specifically, the manufacture of direct-sowing cereal sowing machines, direct sowing, of which they are equipped with flat monodisk type opener devices with deflected angle and semi-pneumatic depth control wheel, placed parallel to the opener disk, and which are intended for sowing in fields without prior tillage, or in fields with large amounts of plant debris or stubble from previous crops.
    This invention is also applicable both for seeders with mechanical dosers, -of those of the type that the seeds fall from the dosers to the groove of the earth by gravity-, as for seeders equipped with pneumatic distributors. BACKGROUND OF THE INVENTION:
    As is well known, there are currently two large groups of direct sowing cereal sowing machines: on the one hand, those that use open devices by means of discs; and, on the other hand, those that use open devices by means of grating. There are also seeders that are equipped with opener devices that combine, at the same time, the disk and the fence, although these types of seeders are less widespread.
    In turn, within the large group of direct sowing cereal seeders, of which devices with discs are used, to open the sowing groove, we can find two large differentiated subgroups: a first subgroup of seeders - which is the most widespread - whose opener devices are equipped with a single flat disk, placed


    with a deflected angle, according to the trajectory of the seeder, and with a depth control wheel adjustable and attached parallel to the disc; and another second subgroup of seeders whose opener devices are equipped with two discs, placed together, with a deflected angle and in the opposite direction, joining at the front and being separated at the rear.
    Once this classification of the different types of opener devices that can be incorporated by direct sowing cereal seeders has been presented, we will continue the description that follows based solely on the type of opener device of those that carry a single flat disk (single disc type) , with a deflected angle, and a semi-pneumatic wheel with adjustable depth control and attached to the disc in parallel, which is the type to which the device presented in this invention belongs.
    Thus, we will highlight that since 1988, the date on which the flat monodisk type opener with a deflected angle and semi-pneumatic wheel with adjustable control was registered in US Pat. "US 4,760806" and said device went on the market, direct sowing sowing of grain cereals equipped with this type of opener device, have become the most demanded sowing and used worldwide, to make direct sowing in fields without previous tillage, or that present large amounts of plant debris or stubble from previous crops.
    At present, -and according to the accumulated knowledge of the applicant of the present invention, after more than 50 years dedicated to the manufacture of seeders-, it is necessary to emphasize that there are only four manufacturers in the international market that produce this type of opener device. And, in particular, of these four existing manufacturers, -which are all outside Europe-, only two of them manufacture and market it; Well, the other two incorporate it into their production process, without selling it separately from the seeders they manufacture.
    In addition, both the initial manufacturer of this type of opener device, and the other three existing manufacturers - who copied it later, after the protection period of the aforementioned Patent - manufacture said opener device, concluded, according to the design that appears in the cited patent. That is, they make said opener device


    practically the same as the opener device registered in 1988, with hardly any changes or improvements in its design and the mode of its manufacture being a mode based on pieces made of cast steel in molds.
    In other words, almost all of the parts that make up the opener devices, of the type registered in the aforementioned Patent, which are currently manufactured, (the central arm that supports the opener disk and the depth control wheel; square tie-down clamps to the seeder frame; the groove closing wheel; the carrying arm of said wheel; and the seed exit boot), and also other smaller parts of said devices, are made of cast steel, in molds
    This type of design of its pieces made of cast steel presents a great and insurmountable inconvenience, since the manufacturing costs of the molds necessary to manufacture said parts are so high that they make the manufacturing of the said opener device economically unfeasible for most of seeder manufacturers, which are forced to acquire these devices, to mount them in their seeders. And this explains, therefore, why in Europe there are so few manufacturers of direct sowing seeders equipped with this type of opener device described here, although as noted, this type of seeders equipped with said opener devices are the most requested in the market, to perform direct sowing.
    In summary, taking into account these considerations and disadvantages described above, the current situation described shows that the design and development of a new device opener, of the flat monodisk type, with a deflected angle, that performs the same work, or that even exceeds the work done for the opener device that currently exists, and that, in addition, at the time of manufacturing it, it exceeds the problem exposed here, -in regard to the need to have to manufacture its pieces in cast steel-, thanks to its innovative and innovative design of all the parts that compose it, constitutes a very advantageous, desirable and necessary option so that the manufacture of seeders with this type of opener device is not problematic, expensive, slow and very little competitive, at least in what refers to European manufacturers .


    To conclude, it is also important to highlight at this point that the design of this new opener device, since it does not need molds for the manufacture of its parts, opens the possibility of manufacturing, without large investments, models of different sizes, as well as the possibility of make different variants that adapt in a more optimal way to the different characteristics of the lands of the areas where the seeders are destined; and all this, in a more agile, competitive way and without the costs of manufacturing the opener device of the type shown here, which currently exists. EXPLANATION OF THE INVENTION:
    The invention described herein refers, -as and as indicated by its corresponding title-, to a new Opener Device for Direct Sowing of Cereals to Chorrillo, of the type of those that open the groove by means of a flat disk placed with deflected angle, and with semi-pneumatic wheel of adjustable depth control, attached parallel to one side of the disk, which also comprises a seed boot that is attached to the other side of the disk and a groove closing wheel located behind said disk.
    This new device opener presents - as and will be described in more detail below - a series of innovations that make it totally different; and that, in short, they turn it into an opener device of the type described here, which has great advantages over current opener devices of the same type, both in the technical field and in the performance of the work to which it is intended; and that, in addition, it is much more competitive, since the costs of its production have been optimized in a very significant way, due to the fact that no piece of those that compose it needs molds to be cast.
    According to the previous statement, the first innovation presented by this new opener device, in relation to the rest of the opener devices of the same type currently in existence, is an innovative design of its entire set, which highlights the fundamental fact that The manufacture of most of the pieces that compose it is very agile and with a very competitive cost, thanks to the design of these pieces


    It makes them made of sheet steel, cutting and boring them by means of laser cutting machines, and without such a need for subsequent machining.
    On the contrary, as noted above, most of the parts that make up the current opener devices of the same type existing on the market are made of cast steel and require much subsequent machining, something that makes its manufacturing a process very complex and expensive, both for the tools necessary to make such mechanization, as for the high cost of the molds necessary to melt said parts.
    The second innovation of this new opener device refers to the fact that said opener device is attached to the structural tube of the frame of a seeder, in a different and more simplified way, by means of two mooring pieces, made of sheet metal, and cut and laser-pierced, which are fitted and welded to said tube, and which guarantee that the position of the opener device will never vary.
    In addition, with this new way of attaching the opener device to the structural tube, another of the problems presented by the current opener devices of the same type is avoided, since said opener devices are attached to the structural tube of the seeder by means of flanges of mooring, which are attached with screws, said abrasurcos devices end up moving, in the very frequent case that they have to work in very stony terrain, and in which many vibrations and blows occur, when forced by the lateral force that produces the opener disk, when working nailed to the ground with a deflected angle.
    The third novelty of the opener device presented here is about the fact that the main piece, which is the one that supports the opening disc, the depth control wheel, the seed exit boot and the closing wheel, It is held and inserted between four connecting rods that allow it to go up and down, without changing its initial positioning, by means of two threaded shafts. These two threaded shafts allow adjustment, at all times, by means of their nuts, for which said shafts are equipped with axial disks, with large friction surfaces, which avoid wear and lateral clearances.


    The fourth innovation presented by the new opener device is the fact that it contains a “traction” spring that is placed on the side of the four connecting rods; specifically, on the side on which the opening disc goes. This spring has a double function: on the one hand, it exerts a downward force on the opening disk so that it penetrates the earth, even if it is hard; and, on the other hand, it counteracts the lateral effort suffered by the main piece, produced by the opening disc itself, when it is nailed to the ground, with a deflected angle, according to the path of the seeder.
    On the other hand, in the current opener devices of the same type, the spring is not of “traction” but of “contraction”. This "contraction" spring is placed centered on the main part, and does not counteract the lateral effort exerted by the opening disc on the main part, as it works at a deflected angle. As a consequence of this, the shaft that supports the main piece suffers wear. And, likewise, there is a slack that causes the main piece to tilt and lose part of its initial deviation angle; and, which, therefore, causes the opener disk not to go in the optimal working position, something that, in short, worsens its operation and effectiveness when opening the groove.
    The fifth innovation is its seed boot, which includes several very advantageous developments.
    A first novelty is that this boot has a groove that is located just above the seed outlet, and that is free and remains above the groove of the earth, when the boot is inserted in said groove. The purpose of this slot is to allow the air to escape, -in the specific case that the opener device is installed in a seeder with pneumatic distributor-, and also to avoid the “blowing” action that occurs at the right time of the Seed fall into the groove, an action that can be taken out of the groove to said seed.
    Unlike the present opener device, the seed outlet boot that incorporates the current opener devices of the same type does not carry this slot, so, in this case, the "blowing" action described above does occur. But, in addition, another consequence of not carrying said groove is that, in some situations where the soil is wet, said earth sticks on the tip of the boot, reducing the groove


    of exit and preventing the air from leaving freely, and slowing the flow of said air that drags the seeds to the boots, so that the seeds are paralyzed and can collapse the tube through which the seeds are transported to the boots, something that, in turn, produces failures of seed fall and, therefore, irregular sowing.
    A second novelty that presents the boot of the new opener device formulated here is that a second wedge with rounded tip has been incorporated, which is placed below the seed outlet and below the first wedge, which is located ahead of Seed output. The mission of this second wedge is to open and clean the deepest and narrowest part of the groove, so that the seeds enter the groove, and do not bounce and go out.
    In contrast to this feature, the boot that incorporates the current opener devices of the same type, only carries the first wedge placed in front of the seed outlet. The problem derived from not presenting the novel second wedge of the new opener device presented here, is that the seeds fall into the groove, at a lower depth, so that these seeds easily bounce and a significant proportion of them are left outside the groove, especially in the specific case that the opener devices are mounted on seeders with pneumatic distributors, which create a "blow" action, just at the critical point of seed fall into the furrow, as noted above.
    Finally, a third novelty that presents the seed boot of the new opener device, unlike the boot that incorporates the rest of current opener devices of the same type, is that it is placed behind the axis of the opener disk. With this different placement, it is achieved that said boot is working in the area where the groove is more open, so, consequently, the boot hardly suffers friction with the earth and, therefore, suffers less wear.
    But in addition, apart from this positive result indicated above, the peculiar placement of the boot in the new opener device presented here also offers other advantages: on the one hand, as the boot just touches the inner wall of the groove created by the disc opener, the shape of the groove is preserved, as created by said


    disk, which is the most suitable form and the one that least breaks the structure of the protective plant layer of the soil. In short, the boot only cleans the inside of the groove, without throwing the earth from the inner wall of the groove. And, on the other hand, another additional advantage offered by the placement of the boot behind the axis of the opening disc is that the moment of the seed fall is delayed, which occurs just at that point where the groove is open in its entirety, a fact that facilitates the ideal placement of the seeds inside said groove.
    On the contrary, in the current opener devices of the same type as the opener device presented here, the boot is not located behind the axis of the opener disk, but in front of said axis. This causes the boot to work in the area where the groove created by the opening disc is not fully open and that the boot suffers a lot of wear. In addition, as a result, the boot forces the inner wall of the groove, throwing the earth; and destroys the shape of said groove, breaking a large part of the protective plant layer of the soil. And even, on the other hand, the moment of the fall of the seeds into the furrow occurs at a point where the opening disc has not opened said groove at all, so it is more problematic and difficult to get all the seeds to remain inside the groove.
    Continuing with the description of the new opener device, the sixth innovation consists in its closing wheel, which also presents several advantageous novelties, compared to the current opener devices of the same type.
    A first novelty is that both its inclination and its direction can be regulated; and even the distance from the tread to the center of the groove that opens the disc can be regulated. All these options are achieved by means of a 10º bent axle, which can be turned and which can also be moved inside the arm that supports said wheel. These regulations allow adjusting the tread of the wheel to the groove, so that with a single wheel we can press the seed against the ground; and, at the same time, we can deposit some land on the seeds, to cover them and leave them buried in the furrow, always according to our criteria on how to do it, since all this depends on how the position of said closing wheel


    Another novelty of the closing wheel is that it has a flat and wavy surface, on its outer perimeter. This surface leaves a wavy footprint, stepping on the groove, and makes a few small holes in the ground, in which a small amount of water is stored when it rains. For this reason, the novel surface of this closing wheel allows better use of water, facilitating the germination of seeds, in case of shortage of rain.
    Finally, the seventh innovation refers to maintenance. In relation to this concept, it is necessary to underline that, from the first moment that the design of the opener device presented here began, it was based on an essential premise and widely demanded by many farmers: the need to achieve that none of the pieces that make up the new device opener need lubrication of some kind.
    For this reason, the new opener device incorporates, in the four axles of the connecting rods and in the axle that holds the arm of the closing wheel, nitrided bushes and friction discs of polyamide, which do not need greasing of any kind. And, on the other hand, on the axis of the opening disc, on the axis of the semi-pneumatic wheel and on the axis of the closing wheel, ball bearings of type 2RS have been mounted, with grease whose duration is “for life” .
    On the contrary, the current opener devices of the same type to the opener device presented here carry several greasers in each opener device, in particular, an amount multiplied by the total number of opener devices comprising a seeder machine, results in a number high number of grease nipples, which entail having to spend considerable time in greasing the parts that make up said abrasurcos devices of the seeder, a task that is uncomfortable, not very accessible and, in a way, painful, due to the location of said parts; and that, in addition, requires two people to do it.

    Next, from the Figures included in the present invention, and with the help of the numbering given to each element, an Example of a Preferred Embodiment of the new opener device presented here is described.
    This example consists of a new opener device for the Direct Sowing of Cereals to Chorrillo, of the flat monodisk type with a deflected angle, with semi-pneumatic wheel of adjustable depth control, attached parallel to the disk.
    Said opener device carries in the center a main piece (1), which is completely flat; It is made of sheet metal, cut and perforated with laser; and it is mounted by means of two threaded shafts (6B, 6D) and embedded between four connecting rods (14), which allow it to go up and down, without changing its initial position.
    This main part (1) supports the following elements: the opening disc (15), which is offset by an angle of 7 °; the semi-pneumatic wheel (16) of adjustable depth control, attached parallel to the opening disk (15); the flexible plate (25), which joins the female tube (22) with the main part (1) by welding; the boot (3) of seed output; and the groove closing wheel (18).
    In relation to the four connecting rods (14) mentioned above, a projection (11) has been extended, in the two connecting rods (14) placed in the lower part, which stops on the structural tube (17) of the seeder frame . Said projection (11) has the function of limiting the downward travel of the main part (1) and of all the elements that we have indicated that support said main part (1).
    Likewise, the four connecting rods (14) have four threaded shafts (6A, 6B, 6C, 6D), which allow adjustment at all times, (the threaded shafts (6B, 6D) being the two threaded shafts on the


    that the main part (1) is mounted. And, in addition, to protect said connecting rods (14) from wear, as well as the clamping arm (7) of the closing wheel (18), they have been mounted on said threaded shafts (6A, 6B, 6C, 6D, 23), nitriding bushings and friction discs (13) that do not need lubrication. These friction discs (13) absorb axial loads and have been manufactured with a very large friction surface, in relation to all the standard friction discs on the market; specifically, said discs (13) have an outer diameter that exceeds the diameter of the axes (6A, 6B, 6C, 6D, 23) where they are placed, multiplied by three.
    The semi-pneumatic wheel (16) of depth control can also be regulated, through a regulation lever (19), which very comfortably allows to raise or lower said wheel (16), and which can set the selected position by means of a pin (21), which is inserted in any of the holes that are staggered and that determine the height at which this wheel is to be located (16).
    In this preferred embodiment, the seed outlet boot (3) can also be contemplated, in which a groove (5) has been made, so that the air used by the pneumatic distributors can escape, to transport the seeds from said seeds. distributors up to the boot (3).
    In addition, the seed boot (3), which is wedge-shaped in front, also comprises a second wedge (4), which ends in a rounded tip at the bottom; which is placed below the seed outlet and below the first wedge described above; and that when passing through the groove, it cleans and widens the deepest and narrowest area of the bottom of the groove, making it easier for the seeds to enter to the bottom of the groove, which prevents them from bouncing and leaving out of the groove.
    Following the description of the seed boot (3), it can be seen that this boot (3) is placed behind the axis (24) of the opening disc (15). It should also be noted that a captive screw (8) is provided, which allows, on the one hand, that the height position of said boot (3) can be adjusted; and that, on the other hand, the front part of said boot (3) can also be adjusted to the disc (15), turning the boot (3), until it


    is adjusted, to prevent the introduction of plant debris between the disc (15) and the boot
    (3) seed output.
    On the other hand, the figures included in the present invention also allow the two mooring parts (2) of the device to be opened to the structural tube (17) of the frame of a seeder. These two mooring pieces (2) are fitted and welded to said structural tube (17); and they are responsible for supporting the entire device openers, by means of two threaded shafts (6A, 6C) and the four connecting rods (14).
    Also, the traction spring (10) can be observed, which fulfills two functions: the first function is a downward force that helps the opener disk (15) get stuck in the ground; and the second function is to counteract the lateral force suffered by the main piece
    (1) produced by the opener disk (15). More specifically, if we look at the drawing in Figure 2, in which we see the device open from above, we will see the opening disk (15) positioned at a deflected angle. This opening disc (15), as previously indicated, exerts a lateral force on the main piece (1), when it advances stuck in the ground, which tends to displace the main piece (1), together with the four connecting rods (14) that hold it, to the right, according to the direction of travel.
    However, to prevent this from happening, the traction spring (10) has been placed to the left of the main part (1) and of the four connecting rods (14). This spring (10), being "traction" and being placed on one side of the connecting rods (14), exerts a force that tends to move to the left, both said connecting rods (14) and the main piece (1), being all these pieces together. And this shift to the left counteracts the force exerted by the opening disk (15) to the right; and, likewise, it prevents the axles (6A, 6C) from suffering wear, which are the most affected as they have to withstand the lateral force from a greater distance.
    The carrier arm (7) of the closing wheel (18) rotates from the shaft (23) that joins it to the main part (1), allowing the closing wheel (18) to adapt to the ground. This carrier arm (7) of the closing wheel (18) is provided with a spring (20) that increases the pressure of said wheel (18) to the ground. And, in addition, it has been provided with a stop (26), which limits the downward movement of said wheel (18). Said stop (26) is an extension that


    it has been welded in front of the carrier arm (7), so that when the arm (7) rotates from the shaft (23) and lowers from the rear, the stop (26) in front of it goes up to a point in the which collides with a bushing that is in its path and attached to the main piece (1).
    5 In turn, the closing wheel (18) has, in its outer perimeter, a flat and undulating seating surface. This closing wheel (18) is attached to the carrier arm (7) by means of an axle (9), which has the peculiarity that it is curved; and this allows the direction and inclination of said closing wheel (18) to be varied, by rotating said axis (9).
    10 This bent shaft (9), moreover, travels inside the arm (7) and is fixed by means of a captive screw (12). When moving, we can vary the distance from the tread of said wheel (18) to the center of the groove, all these regulations being decisive, since they are what make the amount of land that will remain
    15 above the seeds, something that is very important and that varies depending on the area where the planting is taking place.
