Abstract
Dispositivo de regulación de la profundidad de siembra, que siendo aplicable a cualquier máquina sembradora provista de un bastidor rodante y de rejas, discos o cualquier otro tipo de órganos de enterrado de la semilla, se caracteriza porque consiste en una rueda (1), colocada a la misma altura que los citados órganos de enterrado (2) y provista de un soporte (3) en el que se establecen microrruptores (10) que cuando la rueda (1) pierde el nivel de enterrado previsto para la semilla, actúan sobre electroválvulas hidráulicas que a su vez accionan cilindros establecidos en el chasis (8) de la sembradora, provocando las variaciones instantáneas en la misma necesarias para corregir las irregularidades del terreno.Device for regulating the sowing depth, which being applicable to any sowing machine equipped with a rolling frame and grates, discs or any other type of seed burial organs, is characterized in that it consists of a wheel (1), placed at the same height as the said buried bodies (2) and provided with a support (3) in which microswitches (10) are established that when the wheel (1) loses the level of buried required for the seed, they act on solenoid valves hydraulics that in turn actuate cylinders established in the chassis (8) of the seeder, causing the instantaneous variations in the same necessary to correct the irregularities of the land.
Description
Dispositivo de regulación de la profundidad de siembra. Sowing depth regulation device.
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se refiere a un dispositivo acoplable a cualquier máquina sembradora, con la finalidad de controlar automáticamente la profundidad a la que está realizando la siembra en todo momento. The present invention relates to a device that can be coupled to any sowing machine, with the purpose of automatically controlling the depth at which it is sowing at all times.
El objeto de la invención es conseguir un djspositivo que permita mantener en todo momento la profundidad de siembra, es decir la profundjdad a la que se depositan las semillas sobre el terreno, con independencia de cualquier agente perturbador, como puede ser las irregularidades del terreno, el estado del suelo, el peso de la máquina, etc. The object of the invention is to achieve a device that allows the planting depth to be maintained at all times, that is to say the depth at which the seeds are deposited on the ground, independently of any disturbing agent, such as irregularities of the ground, soil condition, machine weight, etc.
La invención se sitúa pues dentro del ámbito de la maquinaria agrícola. The invention thus falls within the scope of agricultural machinery.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Cualquier sembradora está dotada de medios para regular la profundidad de siembra, medios que en ocasiones son hidráulicos yen otras mecánicos, pero que en cualquier caso permiten variar el posicionamiento de la reja que va a abrir el surco sobre el terreno, y consecuentemente el nivel de profundidad a que se quiere depositar la semilla. Any seeder is equipped with means to regulate the sowing depth, means that are sometimes hydraulic and in other mechanics, but that in any case allow to vary the positioning of the fence that will open the groove on the ground, and consequently the level of depth to which you want to deposit the seed.
Esta solución, perfectamente válida desde el punto de vista teórico, presenta en la practica problemas importantes ya que, por ejemplo, dependiendo del peso de la máquina y el eSlado del lerreno, de las roderas que el tractor haga sobre éste último, así como de otros agentes externos, el valor real de la profundidad de siembra puede desviarse considerablemente con respecto a la COla teórica elegida, y además djcha profundjdad varía sustancialmente a lo largo de un surco, por las propias variaciones del terreno. This solution, perfectly valid from the theoretical point of view, presents in practice important problems since, for example, depending on the weight of the machine and the eSlado of the land, the roads that the tractor makes on the latter, as well as other external agents, the real value of the sowing depth can deviate considerably with respect to the chosen theoretical strain, and in addition the depth varies substantially along a groove, due to the variations in the terrain.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
El dispositivo de regulación de la profundidad de siembra que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, asegurando un valor para dicha profundidad de siembra permanentemente constante, con independencia de cualquier tipo de agente externo que pueda tender a variarlo. The planting depth regulating device proposed by the invention solves in a fully satisfactory manner the aforementioned problem, ensuring a value for said permanently constant planting depth, regardless of any type of external agent that may tend to vary it.
Para ello y de forma mas concreta el dispositivo que la invención propone está constituido a partir de una rueda, colocada a la altura de los órganos de enterrado de la semjlla, ya sean éstos rejas, djscos o cualquier otro tipo de abresurcos, rueda fijada con carácter amovible al chasis de la sembradora, para regular su altura operativa, contando el soporte de dicha rueda con microrruptores, que al igual que la propia rueda han sido previamente regulados para fijar la profundidad de siembra, microrruplOres que comandan unas electroválvulas hidráulicas que abren o cierran un circuito en el que participan cilindros o pistones hidráulicos sujelos al chasis de la máquina y que hacen variar la altura de dicho chasis en función de las ordenes recibidas, o lo que es lo mismo, en función del nivel de profundidad que en cada momento adoptan los abresurcos de la máquina sembradora. For this, and more specifically, the device that the invention proposes is constituted from a wheel, placed at the height of the buried bodies of the semjlla, whether they are grilles, djscos or any other type of opener, wheel fixed with removable character to the seeder chassis, to regulate its operating height, counting the support of said wheel with microswitches, which, like the wheel itself, have been previously regulated to set the sowing depth, microswitches that command hydraulic solenoid valves that open or they close a circuit in which hydraulic cylinders or pistons participate, fasten them to the chassis of the machine and vary the height of said chassis depending on the orders received, or what is the same, depending on the level of depth that at each moment They adopt the openers of the seeder machine.
