The object of the invention is to provide a banana harvester intended to be mounted and driven by a tractor vehicle, and also in a self-transported chassis to achieve mechanization and therefore an economic saving in the tasks required in the harvesting of bananas, since The machine of the invention is capable of cutting the pineapple of bananas directly from the plant, transporting that pineapple through the farm and depositing it directly on the cages, guaranteeing the ideal transport to the
packaging.

Antecedentes de la invenciónBackground of the invention

Actualmente la recolección de plátanos supone un costo económico muy elevado para el productor, ya que no solamente se da el problema de la escasa mano de obra y la poca especialización en relación con el sector, sino que cuando se encuentra dicha mano de obra ésta resulta notablemente cara, lo que en definitiva da lugar a que el futuro del cultivo de plátano se vea comprometido por su falta de rentabilidad.Banana harvesting is currently a very high economic cost for the producer, since not only there is the problem of low labor and low specialization in relation to the sector, but when find this workforce it is remarkably expensive, which it definitely gives rise to the future of banana cultivation  Committed to its lack of profitability.

Por otro lado, hay que añadir el hecho de que la recolección manual lleva consigo un transporte por operarios del lugar de corte de la piña de plátanos hasta el remolque o lugar de carga, operación que se realiza con la piña sobre los hombros, dando lugar al deterioro de un elevado porcentaje de plátanos.On the other hand, we must add the fact that the manual collection carries with it a transport by operators of the cutting place of the pineapple of bananas to the trailer or place of load, operation that is performed with the pineapple on the shoulders, leading to the deterioration of a high percentage of bananas.

Descripción de la invenciónDescription of the invention

La cosechadora que se preconiza, ha sido concebida para resolver la problemática anteriormente expuesta, basándose en una estructura de gran robustez y con medios de acoplamiento a un vehículo tractor, como si se tratase de una apero más. No obstante, la cosechadora puede ser montada sobre un chasis autoportante.The harvester that is recommended, has been designed to solve the problem described above, based on a structure of great robustness and with means of coupling to a tractor vehicle, as if it were an implement plus. However, the combine can be mounted on a chassis self-supporting

Más concretamente, la cosechadora de la invención se constituye a partir de un bastidor con los medios apropiados de acoplamiento al vehículo tractor, sobre cuyo bastidor va montado articuladamente un mástil tubular susceptible de inclinarse hasta un ángulo de aproximadamente 30º respecto del suelo, con la finalidad que más adelante se expondrá, con la especial particularidad de que sobre dicho mástil va montada articuladamente un brazo telescópico en horizontal, portador en su extremo libre de una pinza accionable mediante un cilindro hidráulico o neumático, que abraza el tallo de la piña para llevar a cabo el seccionado de éste por medio de una cuchilla dispuesta convenientemente en el extremo del brazo telescópico y accionada por otro cilindro hidráulico o neumático, todo ello de manera tal que la inclinación que puede experimentar el mástil, a través del accionamiento de un tercer cilindro, hidráulico o neumático, permite adaptarse a una falta de verticalidad del tallo de la piña de plátanos, como consecuencia de su poca altura, y así permitir el seccionado de todo tipo de tallos y por lo tanto de piñas de plátano.More specifically, the harvester of the invention is constituted from a frame with the means appropriate coupling to the tractor vehicle, on whose frame a tubular mast capable of lean to an angle of approximately 30 ° from the soil, with the purpose that will be exposed later, with the special feature that is mounted on said mast articulated a horizontal telescopic arm, carrier in its free end of a clamp operated by a cylinder hydraulic or pneumatic, which hugs the stem of the pineapple to carry the sectioning of the latter by means of a knife arranged conveniently at the end of the telescopic and powered arm by another hydraulic or pneumatic cylinder, all in such a way that the inclination that the mast can experience, through the drive of a third cylinder, hydraulic or pneumatic, allows to adapt to a lack of verticality of the pineapple stem of bananas, as a result of its low height, and thus allow the sectioning of all kinds of stems and therefore of pineapples banana.

Los movimientos que efectúa el conjunto de la cosechadora o máquina son:The movements made by the whole of the combine or machine are:

--
Apertura y cierra de la pinza accionada por el correspondiente cilindro;Opening and closing of the operated clamp by the corresponding cylinder;

--
Desplazamiento de la cuchilla de corte, accionada por el segundo cilindro;Cutting blade offset, actuated by the second cylinder;

--
Rotación del brazo telescópico sobre cojinetes, mediante la acción de un elemento inclinado, volviendo a la situación de reposo por gravedad;Rotating telescopic arm over bearings, by the action of an inclined element, returning to the situation of rest by gravity;

--
Alargamiento y retroceso del brazo telescópico y por lo tanto del extremo del mismo, con aproximación y transporte de la pinza y de la cuchilla de corte, de manera que tal brazo telescópico es accionado por un cilindro como los anteriores;Lengthening and recoil of the arm telescopic and therefore the end of it, with approximation and transport of the clamp and the cutting blade, so that such a telescopic arm is actuated by a cylinder like the previous;

--
Inclinación del mástil formando un ángulo respecto del suelo, con objeto de variar la altura del extremo donde va la pinza de agarre, habiéndose previsto que el accionamiento de esa inclinación puede llevarse a cabo mediante el ya comentado cilindro, y opcionalmente por medio del propio vehículo tractor, en caso de incorporar éste medios que posibiliten llevar a cabo esa regulación o inclinación de mástil.Mast tilt forming a angle to the ground, in order to vary the height of the end where the gripper goes, having anticipated that the actuation of that inclination can be carried out by means of the already commented cylinder, and optionally through the own tractor vehicle, if this means is incorporated that enable carry out that regulation or inclination of mast.

El ángulo de inclinación del brazo telescópico se mantiene constante mediante una biela paralela al mástil, formando un paralelogramo con éste.The tilt angle of the telescopic arm is kept constant by a connecting rod parallel to the mast, forming a parallelogram with this one.

Las ventajas derivadas de la cosechadora referida pueden resumirse en las siguientes:The advantages derived from the combine referred can be summarized in the following:

1.- Únicamente se requieren dos personas para recolección, con la correspondiente reducción de personal frente a los cuatro operarios que normalmente se necesitan en la recolección por el método tradicional.1.- Only two people are required to collection, with the corresponding reduction in personnel compared to the four operators that are normally needed in the collection by the traditional method.

2.- Mayor velocidad de circulación de la fruta por la finca, comparada con la velocidad de un operario a pie.2.- Greater speed of circulation of the fruit around the farm, compared to the speed of an operator on foot.

3.- La piña va suspendida del tallo sobre la propia máquina o cosechadora, por lo que no existe posibilidad de que se produzcan roces por presión sobre el hombro del operario, que como ya se ha dicho da lugar a lesiones en los frutos, pudiéndose estimar esos deterioros o lesiones en un 10% del producto recolectado.3.- The pineapple is suspended from the stem on the own machine or harvester, so there is no possibility of that pressure friction occurs on the operator's shoulder, which, as already stated, results in injuries to fruits, being able to estimate these deteriorations or injuries in 10% of the product collected.

Finalmente decir que la fuerza hidráulica que acciona los diferentes dispositivos de la cosechadora procederá de la bomba del tractor, por lo que habrá que dotar a dicha cosechadora de una caja de distribución hidráulica que disponga de tantas salidas como dispositivos de accionamiento mecánico, accionándose las correspondientes válvulas mediante una botonera que se colocará en el tablero del tractor y que estará unida a la caja de distribución hidráulica por un conjunto de cables unidos por una manguera flexible, pudiendo ser las electro-válvulas accionadas por cualquier otro procedimiento, tal como ondas electro-magnéticas, ultra-sonidos, etc.Finally say that the hydraulic force that operates the different devices of the combine will come from the tractor pump, so it must be provided combine harvester with a hydraulic distribution box that has as many outputs as mechanical drive devices, the corresponding valves are activated by means of a keypad that will be placed on the tractor dashboard and that will be attached to the hydraulic distribution box by a set of attached cables by a flexible hose, being able to be the electro-valves actuated by any other procedure, such as electro-magnetic waves, ultra-sounds, etc.

También es evidente comentar que todos los movimientos de la cosechadora podrán desarrollarse por cilindros hidráulicos o por motores de accionamiento eléctrico, pudiendo incluso dotar a la cosechadora de una máquina de televisión montada en el brazo telescópico, con cruz filar y con dos tornillos de ajuste, con objeto de corregir el error de paralelaje conectada con un visor que se situaría en la cabina junto con la botonadura.It is also evident to comment that all combine movements may be developed by cylinders hydraulic or electric drive motors, being able to even equip the harvester with a mounted television machine on the telescopic arm, with cross-section and with two screws adjustment, in order to correct the parallel error connected with a viewfinder that would be placed in the cabin along with the button.
