    AMORTIGUATION DEVICE FOR AGRICULTURAL APEROS
    DESCRIPTION OBJECT OF THE INVENTION
    The present invention relates to a new damping device for agricultural implements, for example chiseles, fast stands and plows, which is capable of mounting on any implement carrying another alternative damping system. BACKGROUND OF THE INVENTION
    Agricultural machinery (implements) is usually classified according to the work they do: fertilizers, harvesters, brushcutters, motocultores, crushers, chiseles or chisel plows, disc harrows, fast stands, loaders, etc.
    Some of these implements include a chassis and one or more arms in which the elements that make contact with the ground (blades, plows, etc.) are fixed, and in many cases they need a damping between chassis and arm / s to regulate the impact of one's own work in the field.
    There are different types of damping: hydraulic, spring damping, crossbows, and the most modern with elastomers or rubbers. The latter is being used by manufacturing a metal structure that surrounds the chassis of the implement, and placing inside a cylindrical rubber on each side, to have a vertical and lateral damping.
    However, the presently existing embodiments on the market have a propensity to break at certain points, due to the fatigue of the material and the distance of said breaking points to the mooring points. In addition, in the case of spring damping, it turns out - after several studies - that the breaking load of the springs is much higher than that of the arms, failing to take advantage of the elasticity of the springs due to such a large difference, since that the arms are bent or stretched before taking advantage of the total compression capacity of the spring, which implies an underutilization of the spring, which also does not satisfactorily fulfill its damping function on the arm of the implement. Adding also that the springs must be protected and guided with what the cost is rising.
    image2
    If we analyze the damping devices with rubbers we will observe that the assembly of the same is done by placing the rubbers on each side of the chassis, that is to say above, below, in front and behind and fixing them to the chassis by means of a screwed structure that does 45º with the chassis, it is a system that works perfectly when we talk about fast stands or shallow work, since when the machine is working and the arm finds an obstacle in the way it acts as a lever and the whole body that surrounds the chassis rotates around it and releases the The obstacle arm, the problem is that taking into account that the support forms an angle of 45º with the chassis, at the time it is turned more than 22º 30 ”the rubber literally passes to the next side. In other words, the rubber from below passes back, the one from behind passes up and so on and the machine is turned and rendered useless, so that with the conventional rubber system a superficial work can be done but not a work of depth. To get to do a deep job we should block the movement of the rubber with the cost and the inconvenience that this entails. DESCRIPTION OF THE INVENTION
    The device of the invention is applied to implements of the type comprising a chassis and one or more arms that carry the elements that make contact with the ground. It has a configuration that minimizes material fatigue depending on the distance to the mooring points that present solutions present. It also has a simple configuration that allows the use of economic damping elements (elastomers) and the optimization of its use protecting the arms of the implement.
    According to the invention, the device comprises: -a head, which is fixed to the implement chassis, -a tilting, which is fixed to said head by means of a horizontal axis joint transverse to the direction of travel (a screw or a bolt for example), said joint allowing the swingarm to oscillate up and down, and an elastic element that is disposed between the head and the swingarm, and which allows damping and recovery to its initial form of great resilience after deformation, temperature resistance, constant deformation as a function of pressure
    image3
    received and long service life, fulfilling these properties optimally to rubber.
    In this way, for example, in comparison with spring damping, we remove the spring, the protective tube, the upper stop, the lower stop, the spring cover, the nylon cover, the pressure regulating screw, and one of the bolts, etc. - in addition to being mostly oversized springs for the work they do - with the corresponding simplicity of the device, while compared to other elastomer-based systems we have the advantages that our system has a greater clearance that allows work with guarantees when the implement finds an obstacle in its path that needs a
    10 major clearance and that with the standard assembly of four elastomers can not get ..
    In short, the simplicity of the device is total, since it does not imply a change in the way of working with respect to springs or crossbows, but it simplifies both embodiments taking them to their minimum expression, so that it is simply necessary to make the 15 molds to casting of the head and the moving part, and the entire damping system stays in four pieces, with the consequent simplicity, considerable cost reduction and maintenance reduction. In addition, forming these pieces so that the elastic element is as close as possible to the joint, the clearance or escape capacity of the arm is increasing minimizing the amount of arms that when encountering an obstacle
    20 are stretched or split by not having enough clearance to avoid it.
    The choice of the material of the elastic element has been carried out by determining the optimal compression and recovery values through tests, and from this by testing rubbers of different compositions that fit the desired values, taking into account
    25 counts the working temperature, the hardness of the rubber with the appropriate shores, and the resilience of the rubber as a function of the pressure exerted. BRIEF DESCRIPTION OF THE DRAWINGS

    The damping device (1) for agricultural implements (2) of the invention (see fig. 1) is applied to implements (2) comprising a chassis (3) and one or more arms (4) carrying the elements they take contact with the ground, and according to the invention, comprises: a head (5), which is fixed to the chassis (3) of the implement (2), a swingarm (6), which is fixed to said head (5) through an articulation (7) of
    15 horizontal transverse axis, said articulation (7) allowing the swingarm (6) to oscillate up and down, and an elastic element (9) that is arranged between the head (5) and the swingarm (6), of material High recovery capacity after deformation, temperature resistance, constant deformation depending on the pressure received and long service life.
    The elastic element (9) can be of any shape, although it will preferably be spherical in shape due to its geometry and ability to perform constant work. In addition, the elastic element (9) is ideally materialized in rubber because it incorporates the properties sought, and is economical to achieve.
    25
    For its part, the horizontal transverse axis articulation (7) ideally comprises a bolt
    (8) and / or screw since with a single element we are materializing the axis of it.
    The elastic element (9) is preferably housed in a cradle (10) configured
    30 in the head (5) and in the swingarm (6); the head (5) comprising at its rear part (see fig 2) a first semi-cradle (10a), and the swingarm (6) a second semi-cradle (10b) complementary to the first semi-cradle (10a), understood as a cradle a receptacle capable of housing and retaining the elastic element (9) during the operation of the device (1), and understanding as a complementary way that both semi-cribs (10a, 10b) during
    35 operation of the device (1), come into contact with the elastic element (9). The first
    image5
    semi-cradle (10a), or the second semi-cradle (10b) - in the example shown the first -, comprise an expansion gap (11) (which has dimensions equal to or greater than the size larger than the elastic element (9) may adopt in the position of greater travel of the swingarm, without breakage, being able to lack even of lateral closures). In this case, the first half-cradle (10a) contains the expansion gap (11). The second semi-cradle (10b) is configured by a bowl arranged superiorly in the swingarm (6) and directed towards the first semi-cradle (10a). The swingarm (6) therefore in the preferred configuration has two functions: on the one hand it supports the arm (4) of the implement (2) and on the other hand in its upper part it comprises the second semi-cradle (10b) complementary to the first
    10 semicuna (10a).
    In the preferred embodiment, the head (5) comprises in its lower part a first semi-articulation (7a) for the passage of the bolt (8) or pin that configures the joint (7) while the swingarm (6) comprises a second semi-articulation ( 7b) extreme.
    15 The optional arrangement of bushings, not shown, friction resistant interposed in the joint (7), for example nylon, is also provided.
    The head (5), on the other hand, comprises fasteners to the chassis, which in the example shown in the figures (see fig. 1) are embossments (15) and that could also be or comprise 20 welds and / or screws.
    Finally, indicate that the swingarm (6) can comprise the arm (4) of the implement (2) in single-piece configuration, or it can comprise a detachable coupling (16) for interchangeable fixing of the arm (4) of the implement (2) in case of breakage or change of use,
    25 using any commercial arm, being able to place a chisel arm, a semi-bevel arm, a planter arm, a plow arm ... etc, increasing the functionality of the system.
    Describing sufficiently the nature of the invention, as well as the manner in which it is carried out in practice, it should be noted that the provisions indicated above and represented in the attached drawings are subject to modifications in detail as long as they do not alter the fundamental principle.
