Abstract
The present invention relates to a pneumatic gun for plant endotherapy, consisting of a double-action pneumatic piston inside a reservoir provided with a metal protection. The gun has two check valves, the first check valve being in the pneumatic piston at the outlet of the conduit for supplying the phytosanitary liquid from the reservoir to the pressure chamber, and the second check valve being upstream from the injection needle and downstream from the control pressure gauge which comprises a device for selectively bleeding air. The rear cover comprises a needle which closes the compression chamber, such that when the pneumatic piston is closer to the closing cover, the needle opens the check valve to enable the liquid to pass into the compression chamber.
Description
PISTOLA NEUMÁTICA PARA ENDOTERAPIA VEGETAL PNEUMATIC GUN FOR VEGETABLE ENDOTHERAPY
DESCRIPCIÓN DESCRIPTION
Objeto de la invención Object of the invention
Es objeto de la presente invención una pistola neumática para tratamientos de endoterapia vegetal que mejora su funcionalidad y precisión al reducir el número de partes móviles en su interior, mejora la precisión de la dosificación del líquido fitosanitario a inyectar y la visualización de la dosificación de la cantidad de líquido en el depósito. The object of the present invention is a pneumatic gun for plant endotherapy treatments that improves its functionality and precision by reducing the number of moving parts inside, improves the accuracy of the dosage of the phytosanitary liquid to be injected and the display of the dosage of the amount of liquid in the tank.
Antecedentes de la invención Los tratamientos fitosanitarios tienen como objetivos prevenir las plagas, erradicar enfermedades en árboles y plantas, mejorar sus condiciones de resistencia y minimizar los riesgos de enfermedades plantas y en árboles, personas, vegetación, animales y medio ambiente. Una de las técnicas empleadas es la endoterapia vegetal ("Tree Injection" o "Trunk Injections" en inglés), conocida comúnmente como endoterapia, que es un método alternativo de tratamiento fitosanitario del arbolado urbano de bajo impacto ambiental. El sistema consiste en la inyección en el tronco de una sustancia nutritiva o fitosanitaria que es inyectada a través del xilema de la planta en sentido acrópeto. Background of the invention Phytosanitary treatments are aimed at preventing pests, eradicating diseases in trees and plants, improving their resistance conditions and minimizing the risks of plant and tree diseases, people, vegetation, animals and the environment. One of the techniques used is the plant endotherapy ("Tree Injection" or "Trunk Injections" in English), commonly known as endotherapy, which is an alternative method of phytosanitary treatment of urban trees with low environmental impact. The system consists of the injection into the trunk of a nutritive or phytosanitary substance that is injected through the xylem of the plant in an acropetic sense.
La historia de la endoterapia, se remonta al Renacimiento: fue Leonardo da Vinci el que hizo las primeras pruebas con arsénico en los árboles. The history of endotherapy goes back to the Renaissance: it was Leonardo da Vinci who made the first tests with arsenic in the trees.
Esta tecnología, se comenzó a desarrollar en Estados Unidos en los años 90. De allí pasó a Italia, y desde este país está comenzando a extenderse por Europa. This technology began to be developed in the United States in the 90s. From there it went to Italy, and from this country it is beginning to spread throughout Europe.
La endoterapia aporta ventajas respecto a los tradicionales tratamientos aéreos, entre las que destacan la ausencia de nebulización o atomización de productos químicos en el ambiente así como su inocuidad para la salud de las personas (ciudadanos y aplicadores). Además se puede focalizar el tratamiento, evitando así los tratamientos
indiscriminados. Endotherapy provides advantages over traditional aerial treatments, among which the absence of fogging or atomization of chemicals in the environment as well as their safety for the health of people (citizens and applicators). In addition, treatment can be focused, thus avoiding treatments indiscriminate
Con este sistema se pueden tratar tanto plagas como enfermedades criptogámicas con una eficacia prolongada de hasta un año. With this system both pests and cryptogamic diseases can be treated with a prolonged efficacy of up to one year.
Los métodos endoterápicos pueden ser por gravedad, por micro presión o por presión, estos dos últimos se suelen aplicar por pistolas accionadas neumáticamente. The endotherapeutic methods can be by gravity, by micro pressure or by pressure, the latter two are usually applied by pneumatically operated guns.
Las pistolas utilizadas en estos tratamientos de endoterapia por presión son de tipo de las que comprenden un depósito rellenable conectado hidráulicamente con una cámara de presión y conectada hidráulicamente con una aguja de inyección que es la que se introduce en el árbol y por donde se inyecta el líquido fitosanitario. La cámara de presión suele estar dispuesta en el cuerpo de la pistola neumática y está cerrada por su parte trasera por una tapa de cierre que la hermetiza y permite el acceso para su mantenimiento y reparación. En el interior de la cámara de presión se dispone un pistón neumático de simple efecto accionado por el aire a presión procedente de un calderín. Una válvula accionada manualmente mediante un gatillo abre o cierra el paso del aire a presión que mueve el pistón neumático y un dispositivo de dosificación dosifica la cantidad de líquido a inyectar. The guns used in these pressure endotherapy treatments are of the type that comprise a refillable tank hydraulically connected with a pressure chamber and hydraulically connected with an injection needle which is the one that is introduced into the shaft and through which the phytosanitary liquid The pressure chamber is usually arranged in the body of the pneumatic gun and is closed at the rear by a cover that seals it and allows access for maintenance and repair. Inside the pressure chamber there is a single acting pneumatic piston driven by the pressurized air from a boiler. A manually operated valve by means of a trigger opens or closes the passage of the pressurized air that moves the pneumatic piston and a dosing device measures the amount of liquid to be injected.
El depósito rellenable de las pistolas es llenado por el líquido procedente de un depósito exterior, este líquido es impulsado por el aire a presión procedente de un calderín que lo suministra a la presión adecuada, el mismo u otro calderín suministra el aire a presión que mueve el pistón neumático. The refillable tank of the guns is filled by the liquid coming from an external tank, this liquid is driven by the pressurized air from a boiler that supplies it at the appropriate pressure, the same or another boiler supplies the moving pressure air the pneumatic piston
