MÁQUINA LIMPIADORA DE PISTAS DEPORTIVAS DE CÉSPED  LAWN SPORTS TRACK CLEANING MACHINE
ARTIFICICAL  ARTIFICICAL
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se puede incluir en el campo técnico de las máquinas de limpieza dedicadas a la limpieza de pistas deportivas. Más concretamente se permite la limpieza de pistas deportivas de césped artificial como por ejemplo las dedicadas a la práctica de pádel, tenis, fútbol, béisbol, golf, rugby, etc. The present invention can be included in the technical field of cleaning machines dedicated to cleaning sports courts. More specifically, the cleaning of artificial grass sports courts is allowed, such as those dedicated to the practice of paddle tennis, tennis, football, baseball, golf, rugby, etc.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
El césped artificial que se utiliza en las pistas deportivas tiene que llevar un relleno que generalmente una arena de sílice de granulometría que suele estar comprendida entre 0.5 y 0.8 mieras para evitar que las fibras o el pelo del césped se peguen. Así se evita que se curven hacia abajo y se consigue que queden sueltas, consiguiendo un efecto de césped recién cortado, amortiguando la pisada y el bote de la pelota o balón. Asimismo el contenido en sílice de dicha arena tiene que ser generalmente superior al 96%. The artificial grass that is used in sports courts has to be filled with a generally granulometry silica sand that is usually between 0.5 and 0.8 microns to prevent the fibers or hair from sticking. This prevents them from curving downwards and ensures that they remain loose, achieving an effect of freshly cut grass, damping the tread and the ball or ball bounce. Likewise, the silica content of said sand must generally be greater than 96%.
Al estar expuesta a la climatología y el uso, la arena de sílice se apelmaza, quedando la pista con una textura similar a la del hormigón por lo que al pisarla se nota una dureza que puede causar problemas a los deportistas, desde quemaduras en los pies hasta lesiones en rodillas, tobillos y demás partes del cuerpo. Además el juego se dificulta mucho porque la pelota o el balón no botan de forma correcta. Being exposed to the weather and use, the silica sand cakes, leaving the track with a texture similar to that of concrete, so stepping on it shows a hardness that can cause problems for athletes, from foot burns to injuries to knees, ankles and other parts of the body. In addition, the game is very difficult because the ball or the ball does not bounce properly.
Actualmente la forma de mantener las pistas es utilizar unas máquinas que comprenden unos cepillos que pueden ser manuales o mecánicos y que frotan la parte superficial de la pista. El mayor inconveniente de estas máquinas es que no sueltan la arena de sílice ni el pelo o la fibra artificial del césped. Esto conlleva que la limpieza del césped es muy superficial y hay que cambiarlo cada pocos años, aproximadamente unos cuatro años. Este gasto es muy elevado y por ejemplo en una pista de pádel puede llegar a costar unos 4.000€ por cada 200 m2. Currently the way to keep the tracks is to use machines that include brushes that can be manual or mechanical and that rub the surface part of the track. The main drawback of these machines is that they do not release the silica sand or the hair or artificial fiber of the grass. This means that the cleaning of the lawn is very superficial and must be changed every few years, approximately four years. This expense is very high and for example on a paddle tennis court it can cost about € 4,000 per 200 m2.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
La presente invención propone una máquina limpiadora de pistas deportivas de césped artificial que resuelve los problemas anteriormente descritos. The present invention proposes an artificial grass sports track cleaning machine that solves the problems described above.
Como se ha explicado anteriormente, este tipo de pistas deportivas suele tener arena de sílice. Sin embargo también es posible que el material de relleno sea caucho, fibra de coco o cualquier otro material que se pueda desarrollar en el futuro a este fin. Todos estos materiales están granulados cuando se usan en pistas deportivas de césped artificial. La presente invención permite la descompactación del material de relleno independientemente del material concreto del que sea. As explained above, these types of sports courts usually have silica sand. However, it is also possible that the filler material is rubber, coconut fiber or any other material that may be developed in the future for this purpose. All these materials are granulated when used on artificial grass sports courts. The present invention allows the compaction of the filling material regardless of the concrete material of which it is.
La clave de la máquina desarrollada es que comprende un sistema de micro- soplado para romper el material de relleno compactado. Dichos sistema emplea aire comprimido. Para ello la máquina comprende un compresor que proporciona aire a presión que se dirige hacia el suelo de la pista deportiva de césped artificial (que puede ser de pádel, tenis, fútbol, rugby, béisbol, golf, etc.) para romper la capa dura del material de relleno. El compresor está conectado al menos una boquilla dosificadora. Dicha boquilla puede ser en un ejemplo de realización una plataforma con una pluralidad de micro- boquillas. En un ejemplo de realización el compresor está conectado directamente a la boquilla dosificadora y en otra realización se conectan a través de una lanza que permite el paso de aire a su través. The key to the developed machine is that it comprises a micro-blowing system to break the compacted filling material. These systems use compressed air. For this the machine comprises a compressor that provides pressurized air that is directed towards the floor of the artificial turf sports court (which can be paddle tennis, tennis, football, rugby, baseball, golf, etc.) to break the hard layer of the filling material. The compressor is connected to at least one dosing nozzle. Said nozzle can be, in an exemplary embodiment, a platform with a plurality of micro-nozzles. In one embodiment, the compressor is connected directly to the dosing nozzle and in another embodiment they are connected through a lance that allows the passage of air through it.
La boquilla es intercambiable de forma que se puede adaptar el tamaño de la boquilla para dejar pasar más o menos aire en función de las necesidades concretas de limpieza en cada caso. Asimismo en las realizaciones en las que la máquina comprende una lanza se contempla el empleo de lanzas de diferentes tamaños también para poder adaptar la elección a las diferentes necesidades que se tengan en función de la zona de la pista que se limpia, de si la superficie está más o menos dura en función si está más o menos utilizada, etc. The nozzle is interchangeable so that the size of the nozzle can be adapted to allow more or less air to pass depending on the needs Concrete cleaning in each case. Likewise, in the embodiments in which the machine comprises a lance, the use of lances of different sizes is also contemplated in order to adapt the choice to the different needs that are available depending on the area of the track being cleaned, whether the surface It is more or less hard depending on whether it is more or less used, etc.
La boquilla dosificadora de aire permite disminuir la presión de salida del aire comprimido que llega a ella para que no se dañen el pelo o la fibra del césped artificial. Así se consigue sacar todo el material de relleno viejo fuera de las pista. Para completar el mantenimiento de la pista el material de relleno viejo que se ha extraído se repone con material de relleno nuevo. The air dosing nozzle allows to reduce the pressure of the compressed air that reaches it so that the hair or fiber of the artificial grass are not damaged. This is how to get all the old filler material out of the tracks. To complete track maintenance, the old filler material that has been removed is replenished with new filler material.
Adicionalmente para mejorar los resultados la máquina puede comprender unos rodillos de púas que permiten separar y levantar las fibras de césped antes de enviar el aire a presión hacia ellas para que sea más eficaz, y volver a moverlas después para que recuperen su posición original y haya huecos suficientes para poder colocar el nuevo material de relleno. Additionally, in order to improve the results, the machine can comprise barbed rollers that allow the grass fibers to be separated and lifted before sending the pressurized air to them so that it is more efficient, and then move them again to recover their original position and have enough holes to be able to place the new filling material.
Así pues gracias al empleo de la máquina limpiadora de pistas de césped artificial de la presente invención las pistas quedan como nuevas y se alarga la vida del césped artificial más del doble de tiempo. Se puede alargar hasta unos 10 o 12 años. Thus, thanks to the use of the artificial grass track cleaning machine of the present invention, the tracks remain as new and the life of the artificial grass is extended more than twice as long. It can be extended up to 10 or 12 years.
La presente invención puede emplearse para la limpieza de pistas que están aire libre y también para pistas interiores ya que en éstas también se producen problemas de endurecimiento del material de relleno. Este proceso se produce más a largo plazo que en las exteriores ya que al estar cubiertas no les afecta la climatología pero con el paso del tiempo y las pisadas de los jugadores este suelo también acaba endureciéndose. En el caso de las pistas interiores la limpieza se realiza utilizando la máquina descrita en una realización en la que comprende un sistema de aspiración de polvo. Este sistema de aspiración comprende una boquilla de aspiración que queda situada cerca de las boquillas dosificadoras. La boquilla de aspiración evita que se levante polvo ya que esto ensuciaría mucho el ambiente, impidiendo el juego durante un tiempo y además se ensuciarían todas las instalaciones. The present invention can be used for cleaning tracks that are outdoors and also for indoor tracks since hardening problems of the filling material also occur therein. This process occurs more in the long term than in the exteriors since being covered does not affect the weather but with the passage of time and the footsteps of the players this ground also ends up hardening. In the case of the inner tracks the cleaning is carried out using the machine described in an embodiment in which it comprises a dust extraction system. This suction system comprises a suction nozzle that is located near the dosing nozzles. The suction nozzle prevents dust from rising as this would make the environment very dirty, preventing the game for a while and in addition all the facilities would get dirty.

REALIZACIÓN PREFERENTE DE LA INVENCIÓN A continuación se describen con ayuda de las figuras 1 a 4 dos ejemplos de realización de la invención. En las figuras 1 a 3 se representa una primera realización especialmente diseñada para ser empleada cuando hay que descompactar o romper el material de relleno en pistas en las que está muy dura por falta de mantenimiento. En la figura 4 se muestra una segunda realización diseñada para ser empleada como mantenimiento periódico, que puede ser semanal, mensual, trimestral... en función del uso que se le dé a la pista deportiva. PREFERRED EMBODIMENT OF THE INVENTION Two examples of embodiment of the invention are described below with the help of Figures 1 to 4. In Figures 1 to 3, a first embodiment specially designed to be used is shown when the filling material must be decompressed or broken into tracks where it is very hard due to lack of maintenance. Figure 4 shows a second embodiment designed to be used as periodic maintenance, which can be weekly, monthly, quarterly ... depending on the use of the sports court.
La máquina limpiadora de pistas deportivas de césped artificial para practicar por ejemplo pádel, tenis, fútbol, béisbol, rugby o golf que se muestra en la figura 1 está específicamente diseñada para la limpieza de pistas de césped artificial y que tienen material de relleno para evitar que las fibras o el pelo del césped se peguen. The artificial grass sports track cleaning machine for practicing paddle tennis, tennis, soccer, baseball, rugby or golf shown in Figure 1 is specifically designed for cleaning artificial grass courts and having padding material to avoid that the grass fibers or hair stick together.
Como se ha descrito anteriormente, dicho material de relleno termina apelmazándose debido por ejemplo a la lluvia y a las pisadas de los jugadores. La máquina (1 ) comprende un compresor, que no se muestra en las figuras, y que está destinado a generar aire a presión que se emplea para lanzarlo contra el suelo y conseguir así romper la capa dura de material de relleno de las pistas. En un ejemplo de realización de la invención se emplea un compresor de aire de 2600 l/min. Asimismo en vez de un compresor la máquina podría comprender por ejemplo una turbina para conseguir las mismas funciones o bien cualquier otro elemento similar. As described above, said filling material ends up caking due to, for example, the rain and the footsteps of the players. The machine (1) comprises a compressor, which is not shown in the figures, and which is intended to generate pressurized air that is used to throw it against the ground and thus break the hard layer of padding material. In an embodiment of the invention, an air compressor of 2600 l / min is used. Also, instead of a compressor, the machine could, for example, comprise a turbine to achieve the same functions or any other similar element.
En un ejemplo de realización la máquina comprende una lanza (4) de configuración tubular que se aprecia por ejemplo en la figura 2 y que comprende un enganche en su extremo superior destinado a permitir la unión con el compresor de forma que el aire a presión que sale del compresor atraviesa la lanza (4). En un ejemplo de realización la lanza (4) es de 1400mm de largo y un diámetro exterior de 15mm y un diámetro interior de 10mm. El acoplamiento entre el compresor y la lanza (4) se realiza preferente mediante una manguera neumática y una tubería de enganche rápido. En un ejemplo de realización de la invención la tubería de enganche rápido tiene una longitud de 20m de forma que se puede proceder a la limpieza de la pista completa estando situado el compresor fuera de la pista. In an exemplary embodiment, the machine comprises a lance (4) of tubular configuration, which can be seen, for example, in Figure 2 and which comprises a hook at its upper end intended to allow the connection with the compressor so that the pressurized air that Comes out of the compressor through the lance (4). In one embodiment, the lance (4) is 1400mm long and has an outer diameter of 15mm and an inner diameter of 10mm. The coupling between the compressor and the lance (4) is preferably carried out by means of a pneumatic hose and a quick coupling pipe. In an exemplary embodiment of the invention, the quick coupling pipe has a length of 20m so that the entire track can be cleaned while the compressor is located outside the track.
En otra realización de la invención el extremo superior de la lanza (4) comprende un mango ergonómico para mejorar la sujeción por parte del usuario. In another embodiment of the invention, the upper end of the lance (4) comprises an ergonomic handle to improve the grip by the user.
La máquina comprende también una una boquilla dosificadora (5) como se observa por ejemplo en la figura 3 y en la figura 4. En el ejemplo de realización mostrado en la figura 3, el extremo inferior de la lanza (4) está conectado a la boquilla dosificadora (5). Dicha boquilla dosificadora (5) tiene una configuración tubular y comprende unos orificios o unas ranuras a través de las que sale el aire a presión que atraviesa la lanza (4) desde el compresor. La boquilla dosificadora (5) puede tener unas medidas por ejemplo de 200mm, de 400m, etc. o incluso puede tener una salida recta. The machine also comprises a dosing nozzle (5) as seen for example in Figure 3 and in Figure 4. In the exemplary embodiment shown in Figure 3, the lower end of the lance (4) is connected to the dosing nozzle (5). Said dosing nozzle (5) has a tubular configuration and comprises holes or slots through which the pressurized air flowing through the lance (4) from the compressor. The dosing nozzle (5) can have measures for example of 200mm, 400m, etc. or it can even have a straight exit.
En dicho ejemplo de realización el aire a presión que sale por la boquilla (5) sale directamente orientado hacia el suelo de la pista pero al salir por la boquilla (5) después de haber atravesado la lanza (4) no se daña el pelo ni la fibra de césped artificial y se consigue sacar toda el material de relleno de la pista. In said exemplary embodiment, the pressurized air that exits the nozzle (5) goes directly oriented towards the floor of the track but when leaving through the nozzle (5) after having passed through the lance (4) the hair is not damaged or the fiber of artificial grass and it is possible to remove all the filling material from the track.
Asimismo la máquina comprende unas ruedas (6) como se observa en las figuras 3 y 5 que permiten el desplazamiento de la máquina sobre el césped artificial de la pista deportiva. En un ejemplo de realización dichas ruedas (6) son de nylon para poder deslizarse de forma correcta sobre el césped artificial. Asimismo en un ejemplo de realización tienen un diámetro de 30 mm. Como se observa en la figura 2 el hecho de que la máquina comprenda estas ruedas (6) mejora la comodidad de los usuarios de la máquina ya que solo tienen que desplazarse por la pista empujando la lanza (4) que se desplaza sobre las ruedas (6). Además se garantiza que la distancia entre los orificios o la ranura de la boquilla (5) y el suelo de la pista deportiva de césped artificial es la óptima y que se mantiene constante durante toda la operación de limpieza. Likewise, the machine comprises wheels (6) as seen in figures 3 and 5 that allow the machine to move on the artificial turf of the sports court. In an exemplary embodiment, said wheels (6) are made of nylon to be able to slide correctly on the artificial grass. Also in an embodiment, they have a diameter of 30 mm. As can be seen in figure 2, the fact that the machine comprises these wheels (6) improves the comfort of the users of the machine since they only have to move along the track by pushing the lance (4) that moves on the wheels ( 6).

For this, the machine additionally comprises a vacuum cleaner (2), as seen in Figure 1, which comprises a suction nozzle (3) and which is attachable to the lance (4). As can be seen in figure 3, the suction nozzle (3) is on the dosing nozzle (5). In another example of embodiment shown in Figure 4, the machine comprises a body (1 1) in which the compressor, the dosing nozzle (5) and the wheels (6) that allow its movement along the track or field are arranged. Said body (1 1) further comprises a pusher (12) which allows it to be moved comfortably. Likewise, the pusher (12) can comprise a handle (13) so that said movement is carried out in an even more comfortable way for the user.
Adicionalmente la máquina puede comprender al menos un rodillo de púas (10) cuyas púas se introducen en las fibras durante el desplazamiento de la máquina para levantarlo y permitir un mejor acceso a los huecos en los que está el material de relleno viejo o se va a introducir nuevo material de relleno. Additionally, the machine can comprise at least one barbed roller (10) whose barbs are introduced into the fibers during the movement of the machine to lift it and allow better access to the gaps in which the old filling material is or is going to Introduce new filling material.
En un ejemplo de realización como el mostrado en la figura 4 se dispone de dos rodillos de púas (10), uno delante de la boquilla dosificadora (5) y otro detrás de ella. Preferentemente las púas de los rodillos de púas son plásticas y metálicas y están destinadas a entresacar las fibras de la pista deportiva de césped artificial. In an exemplary embodiment, as shown in Figure 4, there are two barbed rollers (10), one in front of the dosing nozzle (5) and the other behind it. Preferably, the barbed roller spikes are plastic and metal and are intended to thin the fibers of the artificial turf sports court.
La máquina puede ser de tracción manual o autotraccionada. The machine can be manual or self-traction.
Preferentemente la máquina está dotada de un motor (9) conectado al compresor que a su vez es el encargado de mandar aire a presión a la boquilla dosificadora (5). Asimismo también permite la tracción de los rodillos de púas en la modalidad de máquina autotraccionada. Preferably the machine is equipped with a motor (9) connected to the compressor which in turn is responsible for sending pressurized air to the dosing nozzle (5). It also allows the traction of the barbed rollers in the autotraction machine mode.
En este ejemplo de realización, ilustrado en las figuras 4, cuando se activa la palanca de mando del motor se transmite la potencia del motor hasta los rodillos de púas mediante una serie de poleas y engranajes. Como se ha descrito anteriormente se encuentra un rodillo de púas en el extremo delantero de la boquilla de aspiración y un rodillo de púas en el extremo posterior de dicha boquilla. In this exemplary embodiment, illustrated in Figures 4, when the engine control lever is activated, the engine power is transmitted to the barbed rollers by means of a series of pulleys and gears. As described above there is a barbed roller at the end front of the suction nozzle and a barbed roller at the rear end of said nozzle.
Además la boquilla dosificadora (4) puede ser una plataforma que comprende una pluralidad de micro-boquillas (8) que permiten un mejor control de la presión del aire que sale por ellas. In addition, the dosing nozzle (4) can be a platform comprising a plurality of micro-nozzles (8) that allow a better control of the air pressure exiting them.
Cuando se activa la máquina, el rodillo de púas (10) dispuesto en el extremo delantero entra en el interior de las fibras de césped, haciendo que éstas se levanten. A su vez la boquilla dosificadora (5) con micro-boquillas (8) se desplaza hacia abajo hasta que las micro-boquillas (8) entran en contacto con el material de relleno, que puede ser por ejemplo arena de sílice. El aire que sale a presión por dichas micro-boquillas (8) rompe la capa de material compactado. When the machine is activated, the barbed roller (10) disposed at the front end enters the inside of the grass fibers, causing them to lift. In turn, the dosing nozzle (5) with micro-nozzles (8) moves down until the micro-nozzles (8) come into contact with the filling material, which can be for example silica sand. The air coming out under pressure by said micro-nozzles (8) breaks the layer of compacted material.
El rodillo de púas (10) dispuesto detrás de la boquilla dosificadora (5) gira de tal forma que vuelve a mover las fibras de césped dejando espacio entre las mismas para que las partículas del material de relleno vuelvan a entrar en su posición. The barbed roller (10) disposed behind the dosing nozzle (5) rotates in such a way that it moves the grass fibers again, leaving space between them so that the particles of the filling material re-enter their position.
Como se ha descrito anteriormente la máquina puede comprender un sistema de aspiración con un aspirador que permite recoger todo el polvo generado en el proceso. En este ejemplo de realización de mostrado en la figura 4 la boquilla de aspiración del aspirador está dispuesta detrás del rodillo de púas (10) que está por detrás de la boquilla dosificadora (5), aunque no se ha representado.
