VEGETABLE WASTE PICKING MACHINE FROM OLIVE CLEANING PROCESSES

OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION

El objeto principal de la presente invención es una máquina picadora de residuos obtenidos de las máquinas limpiadoras de aceituna, que presenta el beneficio de trocear el residuo, y por tanto, disminuir su tamaño y aumentar su densidad, facilitando tanto su almacenamiento como su transporte, haciendo que el producto resultante pueda ser utilizado como biomasa o compost. The main object of the present invention is a waste mincing machine obtained from olive cleaning machines, which has the benefit of chopping the residue, and therefore, decreasing its size and increasing its density, facilitating both its storage and its transport, making the resulting product can be used as biomass or compost.

ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION

El proceso de tratamiento y limpieza de la aceituna genera una gran cantidad de residuos vegetales, compuestos esencialmente por hojas y ramas propias de la limpieza de la aceituna. Estos desechos pueden ser tratados de tal forma que se obtenga un producto compactado y válido para su posterior utilización tanto como biomasa como compost. The process of treatment and cleaning of the olive generates a large amount of plant waste, consisting essentially of leaves and branches of the olive cleaning itself. These wastes can be treated in such a way that a compacted and valid product is obtained for later use as both biomass and compost.

Como antecedente, se ha localizado la patente española ES 2273591 que describe una máquina destinada esencialmente a la trituración mediante seccionado en porciones de tamaño muy reducido de ramas, matorrales, pequeños troncos, etc., procedentes de la poda de bosques, arboledas, florestas, pinares, olivos, matorrales, etc., así como de determinadas plantaciones, o de cualquier otro tipo de zona forestal As background, Spanish patent ES 2273591 has been located, which describes a machine essentially intended for crushing by cutting into very small portions of branches, thickets, small logs, etc., from pruning forests, groves, forests, pine forests, olive trees, thickets, etc., as well as certain plantations, or any other type of forest area

o agrícola, permitiendo su reutilización como materia orgánica para abono, fabricación de compost, alimento para ganado o incluso como combustible en las nuevas centrales de biomasa. No obstante, se desconoce por parte de los inventores, expertos en la materia, de ninguna máquina picadora de residuos vegetales procedentes de procesos de limpieza de aceituna como la descrita a continuación. or agricultural, allowing its reuse as organic material for compost, compost manufacturing, livestock feed or even as fuel in the new biomass plants. However, it is unknown by the inventors, experts in the field, of any vegetable waste grinder machine derived from olive cleaning processes as described below.

DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION

Los desechos procedentes del proceso de limpieza de la aceituna son introducidos en la picadora a través de una cinta transportadora. La cinta transportadora vierte el material sobre la tolva de alimentación, ésta tiene la función de encauzar y distribuir el producto sobre el cuerpo alimentador. Las paredes de la tolva tienen la inclinación adecuada para evitar adherencias del material y va desprovista de cualquier tipo de aristas o saliente que puedan provocar una mala distribución del material sobre el cuerpo alimentador. Waste from the olive cleaning process is introduced into the chopper through a conveyor belt. The conveyor belt pours the material over the feed hopper, which has the function of channeling and distributing the product over the feeder body. The walls of the hopper have the appropriate inclination to avoid adhesions of the material and it is devoid of any type of edges or projection that can cause a bad distribution of the material on the feeder body.

El dispositivo alimentador introduce los desechos provenientes de la limpieza de la aceituna en el interior de la carcasa, que es donde se establece el dispositivo de picado que comprende, al menos, el rotor con los martillos trituradores configurando el eje triturador. The feeder device introduces the waste from the cleaning of the olive inside the housing, which is where the chopper device is established, comprising at least the rotor with the hammer crushers configuring the crusher shaft.

El dispositivo alimentador, incorpora un mecanismo consistente en dos ejes de alimentación, dotados de unas aletas, perpendiculares y solidarias al mismo, estando dichas aletas colocadas al tresbolillo con un desfase de 90º. Ambos ejes giran en sentido contrario y de forma independiente arrastrados por la acción de un motorreductor eléctrico a través de una transmisión por cadenas. Ambos ejes están desalineados entre sus aletas, necesarias para impedir interferencias en el giro. Dichos ejes, además, no se encuentran colocados en el mismo plano horizontal, sino que uno se desplaza respecto al otro, para favorecer en arrastre de la hoja a través de unas pletinas con ranuras en forma de peine y que son parte de la carcasa del dispositivo alimentador. Estas pletinas con ranuras impiden al mismo tiempo el retorno de la hoja picada hacia la tolva de alimentación. The feeder device incorporates a mechanism consisting of two feeding axes, equipped with fins, perpendicular and integral thereto, said fins being placed at the tresbolillo with a 90 ° offset. Both axes rotate in the opposite direction and independently driven by the action of an electric gearmotor through a chain drive. Both axes are misaligned between their fins, necessary to prevent interference in the turn. Said axes, moreover, are not placed in the same horizontal plane, but rather one moves with respect to the other, to favor dragging of the leaf through some plates with comb-shaped grooves and that are part of the housing of the feeder device These plates with grooves prevent at the same time the return of the chopped blade towards the feed hopper.

El dispositivo de picado es un elemento triturador cuya misión es picar la hoja hasta dejarla con el tamaño adecuado para ser desalojada a través de la criba. Dicho dispositivo aloja en su interior un cilindro triturador de inercia, o eje triturador, el cual lleva sujetas a lo largo de su longitud y perímetro unas cuchillas desbrozadoras, solidariamente unidas por su base. Dichas cuchillas pueden estar fijas al eje o permitirles cierta movilidad, al no tener impedido el giro en el plano perpendicular al eje del cilindro, esto permite a las cuchillas que adopten la posición más idónea para realizar el proceso de picado cuando se ven sometidas a la acción de la fuerza centrifuga consecuencia del giro del cilindro. El cilindro gira arrastrado por la acción de un motor eléctrico a través de una transmisión de poleas. El proceso de picado se produce cuando el material queda atrapado entre el eje desbrozador y la estructura de la criba, en donde el paso de las cuchillas pican las hojas, ramas y otros elementos de desecho vegetal hasta dejarlos con el tamaño adecuado para ser desalojados a través de las aberturas de la criba. The chopping device is a crushing element whose mission is to chop the blade until it is properly sized to be dislodged through the sieve. Said device houses inside a crushing cylinder of inertia, or crushing shaft, which has stripping blades along its length and perimeter, joined together by its base. Said blades can be fixed to the shaft or allow them some mobility, since the rotation in the plane perpendicular to the axis of the cylinder is not prevented, this allows the blades to adopt the most suitable position to perform the cutting process when they are subjected to the action of the centrifugal force due to the rotation of the cylinder. The cylinder rotates driven by the action of an electric motor through a pulley transmission. The chopping process occurs when the material is trapped between the clearing shaft and the structure of the screen, where the passage of the blades chop the leaves, branches and other elements of plant waste until they are left with the appropriate size to be evicted to through the openings of the sieve.

Para un mejor mantenimiento de la máquina, el dispositivo triturador va provisto de un lateral abatible a modo de registro, el cual lleva incorporado un mecanismo de seguridad para impedir la apertura del registro cuando el mecanismo está en marcha. For a better maintenance of the machine, the crushing device is provided with a folding side as a record, which incorporates a safety mechanism to prevent the opening of the register when the mechanism is running.

La criba, es una parrilla metálica formada por dos estructuras superpuestas, que permite el desplazamiento de la una sobre la otra, consiguiendo aberturas de diferente tamaño, y como consecuencia, distintos tamaños de picado de hoja. La criba se ha diseñado para aguantar la presión ejercida por el material sometido a la acción del eje desbrozador. Una vez que este material alcanza el tamaño de agujero de la criba, es desalojado al exterior encauzado a través de la tolva de salida. The sieve is a metal grill formed by two superimposed structures, which allows the movement of one over the other, getting openings of different sizes, and as a consequence, different sizes of leaf chopping. The screen has been designed to withstand the pressure exerted by the material subjected to the action of the brushcutter shaft. Once this material reaches the size of the sieve hole, it is evicted to the outside channeled through the exit hopper.

Una vez que el material picado es desalojado, éste se conduce a través de la tolva de salida al exterior de la máquina objeto de la invención, siendo posteriormente transportado con una cinta transportadora, al lugar más adecuado para su tratamiento posterior, que no es objeto de la presente invención. Los criterios de fabricación para dicha tolva de salida, son similares a los de la tolva de entrada, es decir, que las paredes de la tolva comprenden la inclinación adecuada para evitar adherencias del material y estando además desprovistas de cualquier tipo de aristas o saliente que puedan provocar atascos y un mal desalojo del producto picado. Once the chopped material is dislodged, it is conducted through the exit hopper to the outside of the machine object of the invention, being subsequently transported with a conveyor belt, to the most suitable place for further treatment, which is not subject to of the present invention. The manufacturing criteria for said exit hopper, are similar to those of the input hopper, that is, that the walls of the hopper comprise the appropriate inclination to avoid adhesions of the material and being also devoid of any type of edges or projection that they can cause jams and a bad eviction of the chopped product.

Para sustentar todos los elementos anteriormente descritos la máquina va provista de una estructura soporte, cuyas dimensiones podrán ser variables para adaptarla a la ubicación de la picadora en la instalación, dicha estructura va provista de elementos amortiguadores en su base para impedir transmisión de esfuerzos y vibraciones en los puntos en los cuales apoya. To support all the elements described above, the machine is provided with a support structure, whose dimensions may be variable to adapt it to the location of the chopper in the installation, said structure is provided with damping elements at its base to prevent transmission of stresses and vibrations. at the points on which it supports.

Once the material is loaded into the feeder device (2), it is dragged by the action of the upper feed shaft (3), which, with the help of the lower feed shaft (4), collects the plant residue and enters it into the chopper device (5). This drag is favored by the existence of the fins attached to both upper (3) and lower (4) feed shafts.

Los ejes de alimentación superior (3) e inferior (4) se mueven de forma independiente y en sentido contrario, pero con la misma velocidad. Un motor-reductor (10) eléctrico, a través de una transmisión por cadenas, es el encargado de transmitir el movimiento a dichos ejes de alimentación (3,4). The upper (3) and lower (4) feed shafts move independently and in the opposite direction, but with the same speed. An electric motor-reducer (10), through a chain transmission, is responsible for transmitting the movement to said feed shafts (3,4).

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement

The document object of the report describes a vegetable waste chopper integrated by a feeder device, with a feed hopper and two axes with fins perpendicular to the triplet, which rotate in the opposite direction and are driven by a gearmotor. The set is also implemented with a chopper device with inertia crushing cylinder, with brushcutters joined by its base and sieve structure, for the passage of the chopped product depending on the desired size.

Among the documents cited in the search report, D1-D4 has been selected to make the report argumentation.

Document D1 describes a crushing device, consisting of a feed hopper and a pair of crushing rollers propelled by a motor and rotating in the opposite direction. Both rollers have a series of misaligned fins on their surface, relative to each other. Document D2 presents a crusher, integrated by a feed hopper and a lower crushing device with rotor, driven by a motor through a belt or chain transmission. The set is implemented, in its lower part, by a fence that performs the functions of screening. By combining the characteristics of documents D1 and D2, a person skilled in the art could arrive at the characteristics of the application, as defined in claims 1-7, without exercising inventive activity.

Document D3 proposes a crushing mill integrated by a hopper at the base of which a pair of crushing rollers are located, implemented with serrated profile blades, driven by a motor and rotating in the opposite direction. Document D4 proposes a mill with feed hopper and hammer-holder drum, which is complemented by an envelope screen that allows the selection of the crushed product, depending on the size required. By combining the characteristics of documents D3 and D4, one skilled in the art could arrive at the characteristics of the application, as defined in claims 1-7, without exercising inventive activity.

With respect to claim 8, regarding the regulation of the screen size as a function of the sliding of two structures to modify the dimensions of the exit orifice, it is considered an obvious alternative that one skilled in the art could select, depending on the circumstances, among the possible known forms of the state of the art, without exercising inventive activity.

It follows that the application, as set forth in claims 1-8 and based on the cited documents, suffers from a lack of inventive activity for claims 1-8 (Art. 8.1 LP 11/1986).
