El objeto de la invención es conseguir una mejora sustancial en el funcionamiento del dispositivo, alargando además la vida útil del mismo.The object of the invention is to achieve a substantial improvement in the operation of the device, lengthening also the useful life of it.

La invención se sitúa pues en el ámbito de la maquinaria agrícola.The invention thus falls within the scope of the Farm Equipment.

Background of the invention

El laboreo de los viñedos se lleva a cabo normalmente con el concurso de tractores agrícolas que arrastran arados, desplazándose a lo largo de las "calles" definidas entre las alineaciones de cepas. Lógicamente tales arados no pueden acceder a los espacios definidos entre cepas en el seno de cada alineación, a cuyo efecto es conocido dotar a los arados convencionales de cultivadores auxiliares consistentes en cuchillas convenientemente montadas sobre el bastidor de los arados o sobre los brazos de sus rejas, cuchillas basculantes que trabajan los citados espacios definidos entre cepas, pero que se retraen automáticamente al aproximarse a cada una de ellas, para evitar que tales cepas resulten dañadas.The cultivation of the vineyards is carried out normally with the contest of tractors that drag plows, moving along the defined "streets" between strain alignments. Logically such plows cannot access the defined spaces between strains within each alignment, for which purpose it is known to provide plows conventional auxiliary cultivators consisting of blades conveniently mounted on the plow frame or on the arms of their bars, swinging blades that work the cited defined spaces between strains, but that retract automatically when approaching each of them, to prevent such strains are damaged.

Básicamente estos cultivadores de intercepas están constituidos mediante la citada cuchilla solidarizada por uno de sus extremos a un eje sensiblemente vertical, eje accionable mediante un cilindro hidráulico de doble efecto y a expensas de las señales generadas por una varilla sensora, que detecta la presencia de cada cepa y que actúa sobre un distribuidor que hace cambiar el cilindro hidráulico de posición y, consecuentemente bascular a la cuchilla para librar la cepa.Basically these intercepa growers they are constituted by the aforementioned blade supported by one from its ends to a substantially vertical axis, actionable axis by a double acting hydraulic cylinder and at the expense of signals generated by a sensor rod, which detects the presence of each strain and acting on a distributor that changes the hydraulic position cylinder and consequently tilt to the blade to rid the strain.

Estos cultivadores de intercepas, si bien cumplen básicamente la función para la que han sido previstos, presentan en la práctica una serie de problemas que se centran fundamentalmente en los siguientes aspectos:These intercepa growers, although basically fulfill the function for which they have been provided, they present in practice a series of problems that focus fundamentally in the following aspects:

--: Dado que la cuchilla debe penetrar convenientemente en el terreno, lo hace también la extremidad inferior del eje al que está asociada, con el consecuente e indeseable efecto de desgaste de este último.Dice that the blade should conveniently penetrate the ground, it also makes the lower extremity of the axis to which it is associated, with the consequent and undesirable effect of wear of this latest.

--: El grado de penetración de la cuchilla en el terreno es fijo, preestablecido de antemano, y en ocasiones puede resultar excesivo o insuficiente.He degree of penetration of the blade in the ground is fixed, preset beforehand, and sometimes it can be excessive or insufficient.

--: La varilla sensora o palpador presenta también un grado de sensibilidad fija o preestablecida de antemano, que en ocasiones puede resultar excesivo o insuficiente.The sensor rod or probe also has a degree of fixed or preset sensitivity in advance, which sometimes It may be excessive or insufficient.

Description of the invention

El cultivador de intercepas para viñedos que la invención propone resuelve de manera plenamente satisfactoria la problemática anteriormente expuesta, en los diferentes aspectos comentados.The vineyard grower that the proposed invention resolves in a fully satisfactory manner the problematic previously exposed, in the different aspects commented.

Para ello, de forma mas concreta y de acuerdo con una de las características de la invención, la cuchilla sufre un doble acodamiento cerca de su extremidad de fijación al eje, determinante de un escalón que hace que la cuchilla propiamente dicha quede acusadamente desfasada hacia abajo con respecto a la extremidad inferior del eje, lo que permite asegurar que en cualesquiera condiciones de trabajo del cultivador dicho eje se va a mantener integralmente fuera del suelo, sin verse afectado por el rozamiento de la tierra.To do this, more specifically and in agreement With one of the characteristics of the invention, the blade suffers a double bend near its end of attachment to the shaft, determinant of a step that makes the blade properly said is markedly out of phase with respect to the lower extremity of the shaft, which ensures that in any working conditions of the cultivator said axis is going to keep completely off the ground, without being affected by the Earth friction.

De acuerdo con otra de las características de la invención el citado eje está ranurado o estriado longitudinalmente, es decir en el sentido de sus generatrices, de manera que es desplazable axialmente a lo largo del casquillo solidario al chasis y en el que juega, al objeto de poder regular la profundidad de trabajo de la cuchilla, y a cuyo efecto el citado eje recibe el movimiento de un cilindro hidráulico de doble efecto a través de una biela provista de un orificio igualmente ranurado o estriado, con respecto a la que el eje es desplazable.According to another of the characteristics of the invention said axis is grooved or longitudinally grooved, that is to say in the sense of its generatrices, so that it is axially movable along the bushing integral to the chassis and in which he plays, in order to regulate the depth of blade work, and for which purpose the aforementioned axis receives the movement of a double acting hydraulic cylinder through a connecting rod provided with an equally grooved or grooved hole, with with respect to which the axis is movable.

Cabe destacar asimismo el hecho de que el cultivador puede transformarse en hidráulico, por medio de la varilla sensora y el distribuidor a una máquina hidroneumática merced a la incorporación de un acumulador de nitrógeno conectado al cilindro hidráulico de doble efecto, anteriormente citado, dotado de una llave y un manómetro para regular la presión. De ésta manera se obtiene una máquina hidroneumática automática, de manera que el gas hace de muelle, con lo que no hace falta la incorporación de un sistema hidráulico constante.The fact that the cultivator can be transformed into hydraulic, by means of the sensor rod and distributor to a hydropneumatic machine thanks to the incorporation of a connected nitrogen accumulator to the double acting hydraulic cylinder, mentioned above, equipped with a wrench and a pressure gauge to regulate the pressure. This way you get an automatic hydropneumatic machine, so that the gas is a dock, so you don't need the incorporation of a constant hydraulic system.

Finalmente y de acuerdo con otra de las características de la invención, la varilla sensora está asistida por un muelle de tensión regulable mediante un tornillo, en orden a poder variar a voluntad su sensibilidad y adecuarla a diferentes condiciones de trabajo. No obstante el cultivador puede prescindir de dicha varilla, puesto que la resistencia sobre la cuchilla la puede ejercer ejerce la misma cepa, ajustando la sensibilidad en función de la presión de acumulador de nitrógeno.Finally and according to another of the characteristics of the invention, the sensor rod is assisted by a tension spring adjustable by means of a screw, in order to be able to vary your sensitivity at will and adapt it to different working conditions. However the grower can do without of said rod, since the resistance on the blade the can exercise exerts the same strain, adjusting the sensitivity in nitrogen accumulator pressure function.

A la vista de las figuras reseñadas puede observarse como el cultivador que la invención propone está constituido a partir de un chasis (1), que es fijable mediante abarcones (2) al brazo (3) de una de las rejas (4) del arado, pero que puede ser igualmente fijado al bastidor de dicho arado, como se verá mas adelante.In view of the figures outlined you can be observed as the cultivator that the invention proposes is constituted from a chassis (1), which is fixable by embracones (2) to the arm (3) of one of the bars (4) of the plow, but which can also be fixed to the frame of said plow, as will see later.

En dicho chasis (1) participan dos soportes paralelos y superpuestos (5), que por uno de sus extremos se rematan en prolongaciones (6) perforadas, entre las que se establece un tornillo o pasador al que se une articuladamente uno de los extremos del cilindro hidráulico (7) de doble efecto, encargado de suministrar al eje (8) el movimiento giratorio para basculación de la cuchilla (9), mientras que en su otro extremo dichos soportes (5) se relacionan entre sí mediante un tubo (10) atravesado por el eje (8) e incorporan además rodamientos (11) que facilitan el giro del eje.In said chassis (1) two supports participate parallel and superimposed (5), which at one end is they end in perforated extensions (6), among which it establishes a screw or pin that joins one of the ends of the double acting hydraulic cylinder (7), responsible for supplying the rotary movement to the shaft (8) for blade tilting (9) while at its other end said supports (5) are related to each other by a tube (10) crossed by the shaft (8) and also incorporate bearings (11) that facilitate the rotation of the shaft.

La máquina podrá transformarse en una máquina hidráulica mediante la inclusión de un acumulador de nitrógeno, no representado en las figuras, que alimenta al cilindro hidráulico (7), estando dicho acumulador dotado de una llave y un manómetro para regular la presión.The machine can be transformed into a machine hydraulic by including a nitrogen accumulator, not represented in the figures, which feeds the hydraulic cylinder (7), said accumulator being provided with a key and a pressure gauge to regulate the pressure.

El soporte superior (5) incorpora además orificios (12) que permiten la fijación del cultivador, en lugar de al brazo (3) de la reja (4), como en la representación de la figura 1, al bastidor del arado, también con la colaboración de abarcones similares a los anteriormente citados.The upper support (5) also incorporates holes (12) that allow the cultivator to be fixed, instead of to the arm (3) of the fence (4), as in the representation of the figure 1, to the plow frame, also with the collaboration of embracones similar to those mentioned above.

El eje (8) se remata por su extremidad inferior en una placa soporte (13), convenientemente soldada al mismo, a la que se fija a su vez la extremidad correspondiente de la cuchilla (9), la cual sufre inmediatamente antes de su extremo de unión a la placa (13), un doble acodamiento obtuso determinante de un escalón (14) que distancia convenientemente el sector operativo de la cuchilla (9), que se corresponde con esta misma referencia, con la extremidad inferior del eje (8), como se observa en cualquiera de la figuras, de manera que dicho eje trabaja en todo momento sensiblemente distanciado del terreno y sin ser afectado por este último.The shaft (8) is topped by its lower extremity on a support plate (13), conveniently welded thereto, to the which in turn fixes the corresponding tip of the blade (9), which suffers immediately before its end of attachment to the plate (13), a double obtuse bending determining a step (14) how conveniently distance the operating sector from the blade (9), which corresponds to this same reference, with the lower extremity of the shaft (8), as seen in any of the figures, so that said axis works at all times noticeably distanced from the ground and without being affected by this latest.

Tal como anteriormente se ha dicho otra de las características de la invención consiste en la posibilidad de regulación en altura para la cuchilla (9), a cuyo efecto el eje (8) es axialmente desplazable, además de poder girar, y para conseguir este movimiento combinado el eje (8) cuenta con una pluralidad de ranuras o estrías longitudinales (15) y atraviesa una biela (16), accionada por el cilindro de doble efecto (7), biela (16) dotada de un orificio (17) ranurado o estriado complementariamente, estructura que permite que la biela arrastre en su movimiento de basculación al eje (15), pero que este último pueda desplazarse axialmente con respecto a la misma.As previously said another of the characteristics of the invention consists in the possibility of height adjustment for the blade (9), for which purpose the shaft (8) It is axially displaceable, in addition to being able to rotate, and to achieve this combined movement the axis (8) has a plurality of longitudinal grooves or grooves (15) and goes through a connecting rod (16), operated by double acting cylinder (7), connecting rod (16) equipped with a slotted or grooved (17) complementary, structure which allows the connecting rod to drag in its tilting movement to the axis (15), but that the latter can move axially with Regarding it.

Los movimientos de basculación automática de la cuchilla (9) vienen determinados por una varilla sensora (18) que actúa sobre un distribuidor (19) convenientemente fijado al chasis (1) y asistido por un protector (20), como es convencional. Pues bien, dicha varilla sensora (18) está asistida por un muelle (21) con el que colabora un tornillo regulador (22) provisto de una tuerca o palomilla (23), de manera que la variación en la longitud efectiva de dicho tornillo (22) permite regular a voluntad la tensión del muelle (21) y, en consecuencia, la sensibilidad de la varilla (18).The automatic tilt movements of the blade (9) are determined by a sensor rod (18) that acts on a distributor (19) conveniently attached to the chassis (1) and assisted by a protector (20), as is conventional. Well well, said sensor rod (18) is assisted by a spring (21) with which a regulating screw (22) provided with a nut or moth (23), so that the variation in length effective of said screw (22) allows to regulate at will the spring tension (21) and, consequently, the sensitivity of the rod (18).
