Description

PALA CARGADORA D E S C R I P C I Ó N OBJETO DE LA INVENCIÓN  LOADING SHOVEL D E S C R I P C I O N OBJECT OF THE INVENTION
La presente invención se puede incluir en el campo técnico de las palas cargadoras para la recogida de residuos sólidos. Más concretamente, la presente invención tiene por objeto una pala cargadora que permite llevar a cabo la recogida de tierra, arena o residuos sólidos en zonas en las que también está presente un líquido, favoreciendo la separación de las fases sólida y líquida del residuo, evitando así el transporte y almacenamiento de grandes cantidades de líquidos. The present invention can be included in the technical field of loaders for solid waste collection. More specifically, the present invention aims at a loader that allows the collection of soil, sand or solid waste in areas where a liquid is also present, favoring the separation of the solid and liquid phases of the residue, avoiding thus the transport and storage of large quantities of liquids.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Se conocen en el estado de la técnica las palas excavadoras, palas mecánicas o cargadoras que presentan un cazo fijado mediante una pluma y un brazo o balancín a una estructura portante o chasis. Excavator shovels, mechanical shovels or loaders are known in the state of the art that have a bucket fixed by a boom and an arm or rocker to a supporting structure or chassis.
Estas palas permiten la recogida, mediante su cazo, de diferentes residuos generados en balsas y lagunas colmatadas con tierras, en obras, tierra presente en zanjas o similares u otro tipo de residuos que es necesario retirar de una determinada zona. These shovels allow the collection, through its bucket, of different waste generated in rafts and lagoons filled with land, in works, land present in ditches or similar or other type of waste that is necessary to remove from a certain area.
Cuando los residuos sólidos a retirar se encuentran en una zona con la presencia de un líquido, como pueden ser las zanjas donde se ha producido una fuga, o zonas acuosas de donde es necesario retirar barro para destinarlo a una posterior aplicación, el residuo sólido se encuentra mezclado con el agua, con lo que la cantidad de residuo solido a retirar se encuentra muy alejado de la capacidad volumétrica del cazo. Esto hace que sean necesarias muchas más operaciones por parte de la pala para retirar todo el residuo solido necesario, además de que el residuo retirado está mezclado con líquido, lo que hace que se incremente el volumen a trasportar, su coste, y la zona donde se deposita dicho residuo quede encharcada con el líquido, dificultando su gestión. When the solid waste to be removed is in an area with the presence of a liquid, such as ditches where there has been a leak, or aqueous areas from which it is necessary to remove mud for later application, the solid residue is It is mixed with water, so that the amount of solid waste to be removed is very far from the volumetric capacity of the saucepan. This makes many more operations necessary. by the blade to remove all the necessary solid waste, in addition to the waste removed is mixed with liquid, which increases the volume to be transported, its cost, and the area where said waste is deposited is encased with the liquid, making management difficult.
La presente invención solventa todos los inconvenientes anteriores debido a que la pala cargadora permite llevar a cabo la recogida de tierra, arena o residuos sólidos en zonas en la que también está presente un líquido, favoreciendo la separación de las fases sólida y líquida. The present invention solves all the above drawbacks because the loader allows the collection of soil, sand or solid waste in areas where a liquid is also present, favoring the separation of the solid and liquid phases.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
La presente invención resuelve el problema técnico planteado, mediante una pala cargadora que comprende un cazo para la recogida de un producto y una tapa desplazable para llevar a cabo el cierre del cazo una vez que éste ha sido llenado con una mezcla formada al menos por un producto sólido y un producto líquido. The present invention solves the technical problem posed, by means of a loader comprising a bucket for the collection of a product and a movable lid to carry out the closing of the bucket once it has been filled with a mixture formed at least by a solid product and a liquid product.
La pala cargadora comprende además un émbolo de presión desplazable para llevar a cabo la compresión de la mezcla formada por el producto sólido y el producto líquido a través de una ventana presente en la tapa desplazable, donde el conjunto cazo - tapa desplazable comprende unos orificios para llevar a cabo la extracción del producto líquido del cazo una vez comprimida la mezcla. The loader also comprises a movable pressure plunger for compressing the mixture formed by the solid product and the liquid product through a window present in the movable lid, where the movable bucket-lid assembly comprises holes for carry out the extraction of the liquid product from the saucepan once the mixture is compressed.
Opcionalmente, la pala cargadora comprende además unos elementos elásticos que se encuentran unidos por uno de sus extremos al émbolo de presión y por otro de sus extremos a la tapa desplazable para facilitar la inserción del émbolo de presión dentro del cazo a través de la ventana de la tapa desplazable. Optionally, the loader also comprises elastic elements that are attached at one of its ends to the pressure plunger and at the other end of it to the movable cover to facilitate the insertion of the pressure plunger into the bucket through the window of the sliding cover.
La pala cargadora recoge la mezcla formada por el producto sólido y el producto líquido de la manera conocida en el estado de la técnica, la tapa desplazable cierra el cazo para evitar la posterior salida del producto sólido del mismo, el émbolo de presión comprime la mezcla formada por el producto sólido y el producto líquido para separar dentro del cazo el producto sólido del producto líquido, saliendo el producto líquido por los orificios presentes en el conjunto cazo - tapa desplazable. De esta manera, el producto que queda contenido en el interior del cazo de la pala cargadora es principalmente producto sólido, lo que permite su descarga directa en la zona en la que va a ser utilizado o su almacenamiento para su posterior utilización libre de producto líquido. DESCRIPCIÓN DE LOS DIBUJOS The loader picks up the mixture formed by the solid product and the liquid product in the manner known in the state of the art, the movable lid closes the bucket to prevent the subsequent release of the solid product from it, the pressure plunger compresses the mixture formed by the solid product and the liquid product to separate the solid product from the liquid product in the saucepan, leaving the liquid product through the holes in the saucepan - movable lid assembly. In this way, the product that is contained inside the bucket of the loader is mainly solid product, which allows its direct discharge in the area where it will be used or its storage for later use free of liquid product .
