    Frame for a seeder of cereals to flushing stream of direct sowing. Frame (1) for a seeder of cereals to chorrillo folding, of direct sowing of disk, whose novel construction allows to pick up the devices of sowing (3) in a very reduced space. Thanks to this reduction of space, a planter of the type described can be built, equipped with a hopper (4) whose volume doubles approximately the volume of the hoppers that are assembled at present, in similar seeders, without lengthening its chassis, nor widening its transport width. This seeder equipped with said frame (1) meets each and every one of the following three advantageous characteristics simultaneously: hopper (4) of large capacity (5,000 liters); short chassis, with a measurement from the coupling to the axle of the wheels of less than 5 meters; and a transport width of less than 3.05 meters, which makes it a much more competitive machine that meets current demands.

    FRAME FOR A CEREAL SEEDER WITH FOLDING SQUARE OF
    DIRECT SEEDING
    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 Folding Sowing Cereals to Chorrillo, of Direct Sowing, of which they are equipped with sowing devices of those that open the furrows by means of discs, and that are destined to do the seeding in fields without previous tillage, or in fields with large amounts of plant debris or stubble from previous crops.
    BACKGROUND OF THE INVENTION:
    At present, according to the applicant's knowledge of the present invention, there are several models of Chorrillo Cereal Seeders, Direct Sowing, equipped with sowing devices from which the grooves are opened by means of discs.
    We will focus our analysis precisely on those models of Direct Sowing Seeders equipped with this type of opener; and, more specifically, in those that, by their size, are foldable, to be able to circulate on roads and highways. And we will expose, next, the problem that exists around this type of seeders, in relation to the size of the hoppers that they present to carry the seeds and to the length of the chassis on which said seeders are mounted, having generated this problem as that these seeders have been increasing their working width, needing more hopper capacity, and also because of the fact that it is increasingly necessary to increase the competitiveness of farms.

    In this way, the first Folding Sowing Cereals Seeders, with Direct Sowing, equipped with seeding devices of the type that open the grooves by means of discs, which began to be manufactured, had a design characterized by placing the hopper of the seeds on top of the frames of the sowing devices and because said seeders are mounted on a relatively "short" chassis, taking into account the distance between the hitch and the wheel axle of these sowing machines.
    This first group of seeders, which are still being manufactured today, has the advantage that their "short" chassis makes them very manageable and appreciated machines, because they are very practical when sowing in fields of reduced dimensions, and because of their easy maneuverability, both when working and when traveling on narrow and difficult roads.
    However, this type of seeders presents a great inconvenience due to the fact that when the frames carrying the sowing devices of these seeders are folded, in transport position, there is no room to place a "large capacity" hopper, between said Racks and located above the sowing devices, but, on the contrary, said Seeders can only carry a "small" hopper, with a capacity of less than 2,500 liters.
    And this fact of not being able to carry the hopper with a higher capacity generates several problems that reduce its competitiveness: on the one hand, the machine has little autonomy and considerable time losses occur, having to stop filling said hopper very frequently; and, on the other hand, when carrying the small hopper and being able to transport a small amount of seeds, it is necessary that a second tractor with a trailer with seeds be supplied to supply the Seeder, which implies that they have to go to perform the sowing task two tractors and two tractor drivers, something that could be avoided if the capacity of the seeder's hopper were much greater.
    To solve this problem, there is in the market a second group of Sowing Cereals with Folding Chorrillo, of Direct Sowing of Discs, with sowing devices of the aforementioned type, which have kept the chassis design "short" and that
    5
    10

    30
    they have a "large capacity" hopper, placed between the folded frames and located above the sowing devices.
    However, in order to provide said seeders with a "large capacity" hopper, placed between the folded frames and placed above the sowing devices, they have been forced to have to sacrifice the transport width of said machines, that is to say , the transport width of these Seeders, when said Seeders are folded, is much greater than three meters, -which is the regulatory measure-, so that the problem appears when traveling on public roads, something that with such width it is, in many cases, very risky and almost impossible to carry out, if it is to pass through rural populations, with narrow streets, or very narrow secondary roads.
    There is a third group of Folding Chorrillo Cereal Seeders, Direct Disk Sowing, with sowing devices of the aforementioned, which have large capacity hoppers, and whose transport width is equal to 3 meters when said seeders are folded.
    However, in this case, as it is not possible to place the "large capacity" hopper on top of the Racks carrying the sowing devices, - since there is no space between said Sowing Racks, when they are folded in the position of transport-, these hoppers are placed either in front of said Racks, or behind them, which forces the chassis of these Seeders to be much longer, and this generates several problems: on the one hand, it makes said machines be less manageable, that they have less maneuverability, and that they are ineffective and impractical when sowing in small fields; and, on the other hand, it causes these seeders to present many more problems when traveling on narrow roads with very curves closed, or at the time of entering fields whose entrance is narrow and the access road where said entrance is located, it is also, sometimes reaching, even, not being able to enter said fields.
    Finally, there is a fourth group of this type of seeders, with sowing devices of those already mentioned, with low capacity hoppers, and "short" chassis -like the
    5
    10
    fifteen

    25
    30
    First group that we have described- that, in order to transport more seed, they present a second hopper placed in front of the tractor, to give a solution to the problems of lack of capacity of the hopper.
    However, this solution creates visibility problems for the tractor driver; it also creates maneuverability problems, due to the forward extension that it implies; it is a very complex solution, which requires more time when hooking the tractor to the Seeder and mounting said hopper in front of the tractor; and, it is also a very expensive solution, since other pneumatic means are needed that transport the seed from this hopper to the seeder's hopper.
    Summarizing the exposed background, and always in relation to this type of seeders that concerns us, we find a first group of seeders that have a relatively "short" chassis, which makes them the most practical seeders, but with the disadvantage that they carry a "small" hopper, without its design allowing a larger hopper to be carried.
    There is also a second group of seeders that have "large hoppers" and "short" chassis. However, this type of seeders are very wide when they are folded and present many problems to circulate on public roads, since they are machines that are preferably designed to sow on very large farms, without leaving them.
    There is also a third group that have "large" hoppers and that when folded give 3 meters wide, to circulate within the regulations, but that are very long, because they have to carry the hopper in front of or behind the bearer frames of the planting elements, with the problems that we have already described above.
    And finally, there is a fourth group that are like the first group, because they have a "short" chassis, "small" hopper and fold 3 meters, but with the added complexity, in this case, that they have a second auxiliary hopper placed in front of the tractor, to logically increase the volume of your hopper, with the drawbacks already noted.

    In short, the problem that exists today, in relation to seeder machines of the type shown here, is that such machines that are "short", practical and that can circulate without problems on public roads, can not carry hoppers "big", as the market demands. And, in contrast, those that carry "large" hoppers, are either too wide to circulate, or they are very long, generating this the problems that we have previously exposed.
    Therefore, given the limitations presented by the Folding Chorrillo Cereal Seeders, of Direct Sowing, with sowing devices of the type described here, which exist in the market today, the development and manufacture of a new modality of Seed Drills this type, equipped with said sowing devices, which are of a "short" chassis, with a large volume hopper, of 5,000 liters or more, placed above and between the racks carrying the sowing devices, when said Racks go folded; and that, in addition, have a transport width of 3 meters that allows to circulate correctly on the road, it is presented as the necessary solution that will allow to solve the existing problems at present, as well as the ideal solution to the demand more and more Growing, by farmers, of this type of seeders, in line with the need to make the work of the field more competitive, including of course to planting cereals.
    EXPLANATION OF THE INVENTION:
    The present invention relates, as indicated by its corresponding title, to a Rack for a Sowing Cereals with Folding Squirt, of Direct Sowing, with Seeding devices, which open the grooves by means of discs. Said Frame is divided into three sections: a central frame, plus two side frames. The three frames are longitudinally aligned and the three comprise stringers that support the sowing devices.
    The two frames on the sides are folded to reduce the working width of said Seeder and remain in an upright position, to be able to circulate with a measurement of transport width that does not exceed 3.05 meters.

    These three racks have a novel construction that allows the sowing devices to be collected in a very small space, by means of a turn made by the stringers carrying said sowing devices and thanks to spaces that are intended to be occupied by said dispositives.
    This reduction in the space occupied by these devices means that the space between the side frames, when they are in an upright position, is greater than 1.80 meters, which allows a large capacity hopper (5,000 liters or more) to be placed, maintaining the measurement of transport width without exceeding 3.05 meters (which is the measure allowed for the circulation of agricultural machinery).
    And as a consequence of this, the Seeder presented here equipped with said Frame simultaneously comprises the following three advantageous features, something that until now did not exist: it carries a large capacity hopper of 5,000 liters or more; its transport width does not exceed 3.05 meters; and its length from the hitch to the tractor to the axis of its wheels is relatively short, since the hopper is located above the sowing devices, presenting a measurement in said length that does not exceed 5 meters.
    Each of these three racks comprises four structural tube stringers. These stringers are placed in parallel, and located in two different horizontal planes: the first stringer and the third stringer, according to the direction of operation of said Seeder, are placed in the highest horizontal plane; and the second crossbar and the fourth crossbar are placed in the lowest horizontal plane.
    The first and third stringers are joined together, by means of welded cruisers, which are located above said stringers, and form a rigid structure that supports the second and fourth stringers.
    Between the first and third stringers, and below the cruises that join them, there is a free space that is occupied by the first line sowing devices, when said devices are raised and collected to fold the Seeder for transport.

    The second and fourth stringers are free; they rotate on their own axis; and they are the ones that support the sowing devices.
    Behind the fourth stringer there is no other stringer, and there is a free space above it.
    The second and fourth stringers raise the sowing devices, and collect them in a very small space, using the space between the first and third stringers, and the free space above the fourth stringer. To perform this maneuver, the second and fourth stringers rotate on their own axis, driven by hydraulic cylinders.
    Each of the three frames carries, at the ends of the stringers, two pieces with rectangular and flat shape, which cover the ends of said stringers and which are welded to the ends of the first and third stringers, located in the upper plane. And in said rectangular pieces, the axes of rotation of the second and fourth free beams are welded. That is, the axes of rotation of the beams carrying the sowing devices.

    PREFERRED EMBODIMENT OF THE INVENTION:
    With the help of Figures 1, 2, 3, 4, 5, 6 and 7, and with the numbered list of the elements shown in said figures, a preferred example of the invention is described below, which is treated of a Frame (1) for a Cereal Seeder to Folding Direct Sowing Squirt, which comprises planting devices (3) of which the furrows are opened by means of discs.
    As already indicated above, and as can be seen in Figures 1 and 2, the Frame (1) object of the present invention, in its preferred embodiment, is divided into three sections: a central frame (1A), more two side frames (1B, 1B).
    The three frames (1B, 1A, 1B) are aligned longitudinally. And each of them (1B, 1A, 1B) comprises four stringers (2) of structural tube, which are placed in parallel and located in two different horizontal planes: the first stringer (2A) and the third stringer (2A), according to the direction of operation of said Seeder, they are fixed and in the highest horizontal plane; and the second crossbar (2B) and the fourth crossbar (2B) are free and placed in the lowest horizontal plane.
    These free stringers (2B, 2B), - understood by the three racks (1B, 1A, 1B) -, are those that support the sowing devices (3), placed in two parallel lines: first line and second line.
    Each of the three frames (1B, 1A, 1B) have, at the ends of the beams (2), two pieces (8) with rectangular and flat shape, which cover the ends of all the beams (2), and that they are welded only to the ends of the first and third fixed stringers (2A, 2A) located in the upper plane, as shown in Figure 3, in which an elevation view of the end of a Frame (1 ).

    In said rectangular and flat pieces (8), the rotation axes (6) of the second and fourth free stringers (2B, 2B) are welded, that is, the rotation axes (6) of the free stringers (2B, 2B ) carriers of planting devices (3).
    The first and third fixed stringers (2A, 2A) are joined together by means of welded cruisers (5), which are located above said stringers (2A, 2A); leave a free space between said stringers (2A, 2A) and under the cruise ships (5); and form a rigid structure that supports the second and fourth free stringers (2B, 2B). Thus, in Figure 4 an elevation view of the cross-section of a Frame (1) is shown, in which the sections of the four stringers (2), the junction cruiser (5) and the devices are shown. sowing (3) deployed, in working position. While in Figure 5 the same elevation view of the cross section of a Frame (1) is offered, but with the planting devices (3) raised and collected.
    Figure 6 shows an elevation view of the rear part of the Seeder in transport position, with the side frames (1B, 1B) folded, to reduce the working width of said Seeder.
    Before the frames (1B, 1B) of the ends are folded, the sowing devices (3) of the first line are lifted by the second free crossbar (2B), and collected in the free space remaining between the fixed stringers first and third (2A, 2A) and below the cruise ships (5) that join said stringers (2A, 2A).
    And also, as behind the fourth free crossbar (2B), there is no other crossbar (2), and above that free crossbar (2B) there is a free space, the sowing devices (3) of the second line are also elevated for this fourth free crossbar (2B) and collected in said free space.
    To perform this maneuver, the second and fourth free stringers (2B, 2B) rotate on their own axis (6), driven by hydraulic cylinders (7).
    Thus, already in position for transport, the side frames (1B, 1B) remain in an upright position, giving a total width that does not exceed 3.05 meters; and leave a space between
    they (1B, 1B) of more than 1.80 meters, which allows to place a large capacity hopper (4), with a volume of more than 5,000 liters. And this is only possible due to the fact that the sowing devices (3) occupy a very small space.
    5 Figure 7 shows an elevational view of the side of the Seeder in the working position, in which the hopper (4) of the seeds placed on top of the sowing devices (3) is observed.
    According to another embodiment not shown, the frames comprise planting devices 10 of which they open the groove by means of a fence. In this case, a larger number of lines of planting devices is foreseen, which may be three, four, or more lines. And also in this exemplary embodiment not shown, the support stringers of said devices are free, and rotate on their own axis by means of hydraulic cylinders, to collect said devices and reduce the space they occupy.
