Abstract

Frame for a seeder of cereals with a direct-seeding folding sowing. # Frame (1) for a seeder of cereals with a folding sowing, direct sowing of disc, whose new construction allows to pick up the sowing devices (3) in a very space reduced. Thanks to this space reduction, a seeder of the described type 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, which meets current demands.

DESCRIPTION

FRAME FOR A FOLDING CEREAL SEEDER FOR CHORRILLO FOLDING

DIRECT SOWING

TECHNICAL SECTOR:

The field of application of the present invention has as frame of reference the technical sector of the industry whose main activity is the manufacture of agricultural machinery; and, more concretely, the manufacture of seeders of Cereals to Chorrillo Folding, of Direct sowing, of which go equipped with devices of sowing of which open the furrows by means of discs, and that are destined to do the sowing in fields without tillage, or in fields with large amounts of plant debris or stubble from previous crops.

BACKGROUND OF THE INVENTION:

At present, according to the knowledge of the applicant of the present invention, there are several models of seeders of Cereals to Chorrillo, of Direct Seeding, equipped with sowing devices of which open the grooves by means of disks.

We will focus our analysis precisely on those models of seeders of direct seeding equipped with this type of opener; and, more concretely, in those that, due to their size, are foldable, to be able to circulate on roads and highways. And then, we will discuss the problem that exists around this type of seeders, in relation to the size of the hoppers that present to carry the seeds and the length of the chassis on which said seeders are assembled, having generated this problem to measure that these seeders have been increasing their width of work, needing more capacity of hopper, and also by the fact that it is increasingly necessary to increase the competitiveness of agricultural operations.

In this way, the first seeders of cereals to Chorrillo Folding, of Direct Seeding, equipped with devices of sowing of the type of those that open the furrows by means of disks, that began to be manufactured, presented a design characterized by placing the hopper of the seeds on top of the racks carrying the sowing devices and for being said seeders mounted on a relatively "short" chassis, taking into account the distance between the coupling and the axle of the wheels of these seeders.

This first group of seeders, which are still manufactured today, has the advantage that their "short" chassis makes them very manageable and appreciated machines, because they are very practical when sowing in small fields, and because of their easy maneuverability, both when working and when driving on narrow and difficult roads.

However, this type of seeders presents a great disadvantage derived from the fact that when the frames carrying the sowing devices of these planters are folded, in transport position, there is no space to place a hopper of "large capacity", between said Racks and located above the sowing devices, but, on the contrary, said Sowers can only carry a "small" hopper, with a capacity of less than 2,500 liters.

And this fact of not being able to take 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 is lost, having to stop filling the hopper very often; and, on the other hand, when carrying the small hopper and being able to transport a small quantity of seeds, it is necessary that a second tractor with a trailer with seeds to supply the Planter, which means that they have to go to carry out the sowing task. two tractors and two tractor operators, something that could be avoided if the capacity of the seeder's hopper was much greater.

To solve this problem, there is a second group of seeders of cereals to Chorrillo Folding, Direct Sowing Discs, with sowing devices of the type mentioned above, which have maintained the design of chassis "short" and that

5

they present a hopper of "great capacity", placed between the folded frames and located on top of the sowing devices.

However, in order to be able to equip such seeders with a "large capacity" hopper, placed between the folded frames and located above the sowing devices, they have been forced to sacrifice the transport width of said machines, that is to say , the transport width of these seeders, when said planters are folded, is much higher than three meters, which is the regulatory measure, so that the problem appears when it comes to circulating on public roads, something that with such a 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 seeders of Cereals to Chorrillo Folding, of Direct Sowing of Discs, with devices of sowing of the already mentioned, that present hoppers of great capacity, and whose width of transport is equal to 3 meters when said Planters go folded.

However, in this case, as it is not possible to place the hopper of "large capacity" on the frames carrying the sowing devices, since there is no space between the sowing racks, when these are folded in position transport-, these hoppers are placed either in front of said racks, or behind them, which forces the chassis of these planters to be much longer, and this generates several problems: on the one hand, makes these machines are less manageable, that have less maneuverability, and that are ineffective and impractical at the time of planting in small fields, and, on the other hand, causes these planters to present many more problems when driving on narrow roads and with very curves closed, or at the time of entering fields whose entrance is narrow and the access road where this entrance is located, it is also, reaching sometimes, even, not being able to enter these fields.

Finally, there is a fourth group of this type of seeders, with seeding devices of the aforementioned, with hoppers of little capacity, and "short" chassis -like the

5

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, said solution creates problems of visibility to the tractor operator; it also creates maneuverability problems, due to the prolongation forward that it supposes; It is a very complex solution, which requires more time when hooking the tractor to the Planter and mounting said hopper in front of the tractor; and, it is also a very expensive solution, since it is needed other pneumatic means that transport the seed from this hopper to the hopper of the Sembradora.

Summing up the exposed antecedents, and always in relation to this type of seeders that occupies to us, we found ourselves with a first group of Sembradoras that present chassis relatively "short", which turns them into the most practical seeders, but with the disadvantage that they carry a "small" hopper, without its design allowing to carry a larger hopper.

Also, there is 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 through the public roads, since they are machines that are designed preferably to plant on very large farms, without leaving them.

There is also a third group that have "large" hoppers and when they fold they are 3 meters wide, to circulate within the regulations, but they are very long, because they have to carry the hopper in front of or behind the Racks carrying the sowing elements, with the problems that we have already described previously.

And, finally, there is a fourth group that are like the first group, because they have a "short" chassis, a "small" hopper and fold to 3 meters, but with added complexity, in this case, that they have a second auxiliary hopper placed in front of the tractor, to logically increase the volume of its hopper, with the drawbacks already noted.

In short, the current problem, in relation to the sowing machines of the type here exposed, is that the machines of this type that are "short", practical and that can circulate without problems by the public roads, can not carry hoppers "Big", as the market demands. And, in contraposition, those that carry "big" hoppers, either they are very wide to circulate, or they are very long, generating this the problems that we have already exposed previously.

Therefore, given the limitations of the seeders of Cereals to Folding Chorrillo, of Direct Seeding, with sowing devices of the type described here, that exist in the market today, the development and manufacture of a new form of seeders of this type, equipped with said seeding devices, which are of "short" chassis; with a hopper of great volume, -of 5,000 liters or more-, placed above and between the frames carrying the sowing devices, when said frames are folded; and that, in addition, they have a transport width of 3 meters that allows to circulate correctly along the highway, it is presented as the necessary solution that will allow solving the existing problems nowadays, as well as the ideal solution to the increasingly growing demand, on the part of the agriculturists, of this type of Sembradoras, in consonancia to the need to do more competitive the works of the field, including of course the sowing of cereals.

EXPLANATION OF THE INVENTION:

The present invention refers, as indicated by its corresponding title, to a frame for a seeder of cereals to Chorrillo Folding, of direct sowing, with sowing devices, which open the grooves by means of disks. Said frame is divided into three sections: a central frame, plus two side frames. The three frames are aligned longitudinally and the three comprise stringers that support the planting devices.

The two frames of the sides are folded to reduce the working width of the Planter and remain in vertical position, to be able to circulate with a measure of transport width that does not exceed 3.05 meters.

These three frames present a novel construction that allows to collect the sowing devices in a very small space, by means of a turn made by the beams carrying said sowing devices and thanks to spaces that have been foreseen to be occupied by said dispositives.

This reduction of the space occupied by these devices means that the space left between the frames of the sides, when they are in vertical position, is greater than 1.80 meters, which allows to place a hopper of large capacity (5,000 liters or more), maintaining the measure of width of transport without surpassing the 3.05 meters (that is the allowed measurement for the circulation of agricultural machinery).

And as a consequence of this, the Planter here presented equipped with said Rack simultaneously comprises the following three advantageous characteristics, something that until now did not exist: it carries a hopper of great capacity of 5,000 liters or more; its transport width does not exceed 3.05 meters; and its length from the coupling 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 said three racks comprises four structural tube beams. These stringers are placed in parallel, and located in two different horizontal planes: the first and the third stringer, according to the direction of the said planter, are placed in the highest horizontal plane; and the second spar and the fourth spar 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 cruisers that join them, there is a free space that is occupied by the sowing devices of the first line, when said devices are raised and collected to fold the planter for transport.

The second and fourth beams are free; they rotate on their own axis; and they are the ones that support the planting devices.

Behind the fourth stringer there is no other stringer, and there is a free space above it.

The second and fourth stringers elevate 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 beams rotate on their own axis, driven by hydraulic cylinders.

Each of the three frames carries, at the ends of the beams, two pieces with a rectangular and flat shape, which cover the ends of said beams and which are welded to the ends of the first and third beams, 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 listing of the elements shown in said figures, a preferred example of the invention is described below, which is of a Frame (1) for a seeder of Cereals to Chorrillo Folding Direct Seeding, which includes sowing devices (3) of which open the grooves by means of disks.

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 one of them (1B, 1A, 1B) comprises four stringers (2) of structural tube, which are placed in a parallel manner and located in two different horizontal planes: the first stringer (2A) and the third stringer (2A), according to the direction of running of said planter, they are placed fixed and in the highest horizontal plane; and the second spar (2B) and the fourth spar (2B) go free and placed in the lowest horizontal plane.

These free beams (2B, 2B), -comprised by the three frames (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 stringers (2), two pieces (8) with a rectangular and flat shape, which cover the ends of all the stringers (2), and which they are welded only to the ends of the first and third fixed beams (2A, 2A) located in the upper plane, as shown in figure 3, in which an elevation view of the end of a frame can be observed (1 ).

In said rectangular and flat parts (8), the axes of rotation (6) of the second and fourth free beams (2B, 2B), that is, the axes of rotation (6) of the free beams (2B, 2B), are welded. ) carriers of the seeding devices (3).

The first and third fixed stringers (2A, 2A) are joined together, by means of some welded cruisers (5), which are located above said stringers (2A, 2A); they leave a gap between said spars (2A, 2A) and below the cruisers (5); and form a rigid structure that supports the second and fourth free beams (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 side members (2), the junction cruiser (5) and the devices of sowing (3) deployed, in working position. While in Figure 5 the same elevation view of the cross section of a Rack (1) is offered, but with the sowing devices (3) raised and picked up.

Figure 6 shows an elevation view of the rear part of the Planter in transport position, with the side frames (1B, 1B) folded, to reduce the working width of said Planter.

Before the frames (1B, 1B) of the ends are folded, the sowing devices (3) of the first line are lifted by the second free rail (2B), and collected in the free space remaining between the fixed side rails first and third (2A, 2A) and below the cruisers (5) joining said spars (2A, 2A).

And also, as behind the fourth free stringer (2B), there is no other stringer (2), and above said free stringer (2B) is a free space, the sowing devices (3) of the second line are also high for this fourth free spar (2B) and collected in said free space.

To perform this maneuver, the second and fourth free beams (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 vertical position, giving a total width that does not exceed 3.05 meters; and they leave a space between

they (1B, 1B) of more than 1.80 meters, which allows to place a hopper (4) of great capacity, 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.

Figure 7 shows an elevation view of a side of the planter in working position, in which the hopper (4) of the seeds placed above the sowing devices (3) is observed.

According to another embodiment, not shown, the frames comprise sowing devices 10, which open the groove by means of a grid. In this case, a greater number of lines of sowing devices is foreseen, being able to be three, four, or more lmeas. And also in this example of embodiment not shown, the support beams 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.
