Description
DISPOSICIÓN SOPLADORA DE GRANOS APLICABLE A MÁQUINAS COSECHADORAS GRAIN BLOWER PROVISION APPLICABLE TO HARVESTING MACHINES
CAMPO DE LA INVENCIÓNFIELD OF THE INVENTION
La presente invención se refiere a una disposición sopladora de granos aplicable a máquinas cosechadoras, preferentemente de soja, que permite obtener mayores rendimientos y/o optimización de Ia productividad de Ia cosecha en comparación con las máquinas hasta hoy conocidas. Ello es obtenido merced a Ia generación de una cortina de aire capaz de retener los granos y evitar Ia caída al suelo de los granos que se producen en el cabezal de Ia plataforma de las cosechadoras.The present invention relates to a grain blowing arrangement applicable to harvesting machines, preferably soybeans, which allows to obtain higher yields and / or optimization of the productivity of the crop in comparison with the machines known until now. This is obtained thanks to the generation of an air curtain capable of retaining the grains and preventing the fall to the ground of the grains that occur in the head of the combine platform.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Como es por todos conocido, a medida que el cultivo de soja fue creciendo, y por ende, su importancia en Ia economía interna y del mundo, surgió Ia necesidad de perfeccionar todos los componentes de las cosechadoras a fin de aumentar el rendimiento de trabajo de las mismas.As is known to all, as the soybean crop grew, and therefore, its importance in the internal and world economy, the need arose to improve all the components of the harvesters in order to increase the work performance of the same.
De todas las operaciones que realiza Ia cosechadora, tales como corte, alimentación, trilla, separación, limpieza, almacenaje, descarga y desparramado de los residuos de cosecha, Ia recolección resulta ser Ia parte más importante.Of all the operations carried out by the combine, such as cutting, feeding, threshing, separation, cleaning, storage, unloading and scattering of crop residues, the collection turns out to be the most important part.
Cuando el cultivo de soja está en condiciones de cosecharse, es muy susceptible al desgrane, siendo el gran causante de las pérdidas que ocasiona Ia cosechadora. Del 100% de las pérdidas, el 70% es producido por Ia plataforma o cabezal, calculándose un promedio de 150 kg por hectárea. Dichas mencionadas pérdidas por cabezal son producto de diferentes factores, entre los que se encuentran:When the soybean crop is in a position to be harvested, it is very susceptible to shelling, being the great cause of the losses caused by the harvester. Of the 100% of the losses, 70% is produced by the platform or head, an average of 150 kg per hectare being calculated. Said mentioned losses per head are the product of different factors, among which are:
1 o) el desgrane por frotamiento entre las plantas en el momento de corte de las cuchillas;1 o ) the shearing by rubbing between the plants at the time of cutting the blades;
2o) pérdidas ocasionadas por el enganche y golpe del molinete en el momento que acompaña Ia planta para el corte;2 o ) losses caused by the coupling and blow of the windlass at the moment that accompanies the plant for cutting;
3o) por arrastre y empuje de las plantas que realiza Ia barra de corte cuando Ia velocidad de avance de Ia cosechadora es mayor a Ia velocidad de corte de las cuchillas.3 o ) by dragging and pushing of the plants carried out by the cutting bar when the speed of advance of the combine is greater than the cutting speed of the blades.
Con respecto al arte de Ia presente invención, es decir, a las maquinarias hasta
hoy conocidas y que intentan solucionar el problema planteado, se han realizado consultas al INTA, Instituto Nacional de Tecnología Agropecuaria de Argentina, no habiéndose informado de una máquina que cumpla Ia función del implemento de Ia presente invención.With respect to the art of the present invention, that is, the machinery up to known today and trying to solve the problem raised, consultations have been made to the INTA, National Institute of Agricultural Technology of Argentina, not having been informed of a machine that fulfills the function of the implement of the present invention.
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención basa su fundamento en Ia creación de una disposición de soplado de aire, compuesto por bandejas de retención y soplado para los granos que se van desgranando sobre Ia plataforma y que se van volcando sobre las cuchillas y que finalmente caen al piso, ocasionando las perdidas comentadas en los párrafos anteriores.The present invention bases its foundation on the creation of an air blowing arrangement, composed of retention and blowing trays for the grains that are shelled on the platform and that are tipped over the blades and that finally fall to the floor, causing the losses mentioned in the previous paragraphs.
La colocación estratégica de esta bandeja permite distribuir un soplado de aire continuo a Io largo de toda Ia plataforma, logrando formar así una pared de aire en dirección al sinfín de Ia plataforma. Por Ia acción de esta corriente continua de aire, los granos que se desgranan sobre Ia plataforma se mantienen en ella.The strategic placement of this tray allows a continuous air blowing to be distributed along the entire platform, thus forming an air wall in the direction of the endless platform. By the action of this continuous stream of air, the grains that shed on the platform are maintained in it.
Al mantenerse todos los granos en Ia plataforma, por medio de las plantas que van entrando a Ia misma y Ia corriente de aire continuo generada por el dispositivo de soplado hacen que el cereal desgranado sobre Ia plataforma ingrese al acarreador de Ia cosechadora, pasando a integrar así el rendimiento de Ia cosecha y no Ia pérdida (producto de su caída al suelo).By keeping all the grains on the platform, by means of the plants that are entering it and the continuous air flow generated by the blowing device causes the grained cereal on the platform to enter the harvester of the combine, becoming integrated thus the yield of the harvest and not the loss (product of its fall to the ground).
El dispositivo de soplado se realiza mediante Ia colocación de dos turbinas centrifugas de gran caudal de aire, las cuales pueden ser accionadas por mando mecánico o hidráulico, las cuales en cada salida de aire de cada una de ellas, se colocan cuatro caños o conductos de Ia misma dimensión que permiten que el flujo de aire se distribuya con igual caudal y sean dirigidos a un segundo distribuidor de aire que permite alimentar a las bandejas de soplado con cuatro acoplamientos que posibilitan Ia corriente de aire continua a Io largo de todas las bandejas de Ia plataforma. Las pruebas llevadas a cabo con Ia disposición de aspiración de granos de Ia presente invención han permitido Ia recolección de un gran porcentaje del grano que actualmente se pierde. Sin lugar a duda en base al análisis de los porcentajes mencionados, las mejoras en cuanto a rendimiento de cosecha se han incrementado significativamente. La presente solución aportada cumple en forma acabada con el fin del
proyecto Nacional de eficiencia de cosecha y postcosecha de granos (PRECOP) en Argentina, que tiene por objetivo reducir las pérdidas y mejorar Ia calidad de los granos producidos, en base a un manejo adecuado de nuevas tecnologías.The blowing device is carried out by means of the placement of two centrifugal turbines of great air flow, which can be activated by mechanical or hydraulic control, which at each air outlet of each of them, four pipes or ducts of The same dimension that allows the air flow to be distributed with the same flow and are directed to a second air distributor that allows the blow trays to be fed with four couplings that enable the continuous air flow along all the trays of The platform The tests carried out with the grain aspiration arrangement of the present invention have allowed the collection of a large percentage of the grain that is currently lost. Without a doubt, based on the analysis of the aforementioned percentages, improvements in crop yield have increased significantly. The present solution provided complies with the end of the National project of efficiency of harvest and postharvest of grains (PRECOP) in Argentina, which aims to reduce losses and improve the quality of the grains produced, based on the proper management of new technologies.
La propuesta INTA es reducir en un 20% las pérdidas que se producen durante las etapas de cosecha y postcosecha, Io cual representa un incremento del saldo exportable de 270 millones de dólares anuales. Este objetivo se tuvo en cuenta y se trabajó para que las pérdidas que ocasionan las plataformas, por Ia gran velocidad que desarrollan las cosechadoras en el momento de trilla sean mínimas facilitando el trabajo de las mismas. Con este implemento agrícola se logró recuperar hasta el 80% de las pérdidas que se originan en Ia cosecha de soja.The INTA proposal is to reduce the losses that occur during the harvest and post-harvest stages by 20%, which represents an increase in the exportable balance of 270 million dollars annually. This objective was taken into account and worked so that the losses caused by the platforms, due to the high speed that the harvesters develop at the time of threshing, are minimal, facilitating their work. With this agricultural implement it was possible to recover up to 80% of the losses that originate in the soybean harvest.

DESCRIPCIÓN DETALLADA DE LA INVENCIÓNDETAILED DESCRIPTION OF THE INVENTION
Tal como puede observarse en Ia figura 1 Ia disposición de soplado de una cosechadora A se encuentra constituida por los conductos o tomas de aire libre de
polvo 1 , uno en cada costado de Ia cabina de mando, conductos 1 que se acoplan mediante mangueras flexibles con acoplamiento rápido 2 a respectivas turbinas centrifugas de aire 3. Cada una de dichas turbinas 3 insufla aire a un primer distribuidor de aire, el cual se conecta a través de un caño o conducto de aire 4 a un segundo distribuidor de aire 5.As can be seen in Figure 1, the blowing arrangement of a combine A is constituted by the ducts or air intakes powder 1, one on each side of the control cabin, ducts 1 that are coupled by flexible hoses with quick coupling 2 to respective centrifugal air turbines 3. Each of said turbines 3 blows air into a first air distributor, which it is connected through a pipe or air duct 4 to a second air distributor 5.
En Ia figura 2 vemos como cada turbina de aire 3 distribuye su caudal de aire a través de cuatro conductos 4, que salen desde el primer distribuidor 6 y llegan al segundo distribuidor 5. En Ia parte central vemos a través de las flechas como un distribuidor central de aire 5 recibe caudal de aire desde las dos turbinas 2, cada una aportando aire mediante un conducto 4. Cada uno de dichos segundos distribuidores 5 se conecta a cuatro acoplamientos de goma 7 que conectan a Ia parte inferior de bandejas sopladoras 8 a fin de formar Ia cortina longitudinal de aire a través de Ia abertura 9 que se ubica adyacente a las cuchillas de corte 10 y entre los separadores laterales 1 1 de plataforma. En Ia figura 3 se observa claramente Ia apertura de Ia bandeja sopladora 8 desde cuyo extremo se insufla una corriente o cortina de aire "b". En dicha figura se ilustra Ia turbina sopladora de aire 2 con su primer distribuidor 3 conectado a través del conducto 4 al segundo distribuidor de aire 5, el cual sopla aire con los acoplamientos de goma 7 a Ia parte inferior de las mencionadas bandejas sopladoras 8. La figura 4 muestra Ia conexión de uno de los acoplamientos de goma 7 a una embocadura 13 de Ia bandeja de soplado 8. Por debajo de Ia bandeja de soplado se ubica una tapa plegable 12 para permitir Ia limpieza interior de dicha bandeja 8.In Figure 2 we see how each air turbine 3 distributes its air flow through four ducts 4, which leave from the first distributor 6 and reach the second distributor 5. In the central part we see through the arrows as a distributor air central 5 receives air flow from the two turbines 2, each providing air through a conduit 4. Each of said second distributors 5 is connected to four rubber couplings 7 that connect to the lower part of blower trays 8 in order of forming the longitudinal air curtain through the opening 9 which is located adjacent to the cutting blades 10 and between the platform side separators 1 1. Figure 3 clearly shows the opening of the blower tray 8 from whose end a current or air curtain "b" is blown. This figure illustrates the air blower turbine 2 with its first distributor 3 connected through the conduit 4 to the second air distributor 5, which blows air with the rubber couplings 7 to the lower part of said blower trays 8. Figure 4 shows the connection of one of the rubber couplings 7 to a mouth 13 of the blow tray 8. A folding cover 12 is located below the blow tray to allow the interior cleaning of said tray 8.
En Ia figura 5 se ilustra un corte transversal a fin de observar el ingreso de aire al interior de Ia bandeja de soplado 8 a través de Ia embocadura 13, las flechas internas nos indican el sentido de movimiento de Ia corriente de aire, terminando en Ia cortina de aire 14 que impide que los granos salgan de las bandejas 8 de Ia plataforma y que terminen cayendo al suelo.In Figure 5 a cross-section is illustrated in order to observe the entry of air into the blowing tray 8 through the mouth 13, the internal arrows indicate the direction of movement of the air stream, ending in Ia air curtain 14 that prevents the grains from leaving the trays 8 of the platform and ending up falling to the ground.
Las figuras 6a y 6b permiten ver el detalle de Ia tapa antiobstruccion 15 que cierra por peso propio o gravedad y que resulta abierta por Ia corriente de aire. La misma evita que los granos ingresen al interior de Ia bandeja de soplado 8 en el momento de que las turbinas 2 se encuentran desactivadas.Figures 6a and 6b allow to see the detail of the anti-obstruction cover 15 that closes by its own weight or gravity and that is opened by the air flow. It prevents the grains from entering the inside of the blowing tray 8 at the moment when the turbines 2 are deactivated.
