DESCRIPTION

ECOLOGICAL SPRAYING MACHINE TO REMOVE BAD HERBS.

The Utility Model referred to in the present specification relies on a new machine for propelling liquids to spray weeds, also called unwanted herbs, which, using as a product, water, at high temperatures, preferably at boiling temperature and, spraying it produces a lethal effect on them. The machine itself, which propels the water at high temperatures, can propel the water at any temperature that is programmed. Included at room temperature, for spraying with phytosanitary products or others. It works preferably with electrical energy from the general network or with an electrical current generator, with the possibility of using other energies. Among others, those produced by fuels such as natural gas, propane gas, butane gas, diesel, gasoline, etc., as well as those produced by diesel engines, gasoline engines or of another type.

Said machine provides essential novelty characteristics, with important economic and ecological advantages, with respect to the majority of machines on the market for the same or similar purpose, which are designed to propel water at room temperature mixed with herbicides. These products, in addition to having a high cost price, most of them have toxic substances in their composition that can generate risks to health and the environment.

It is capable of being attached to a rigid chassis or frame, such as a handcart or wheelbarrow, being self-propelled by mechanical or motor means, being attached to a tractor, a quad, or other type of vehicle, as well as being attached to a A trailer. When it is self-propelled by its own motor to move, said motor generates the energy necessary for the total operation of the machine: heating the water, activating the pump, and so on. Being able to be driven by one or more motors independent of it or combined with each other. When it is coupled to a tractor, a quad or another type of vehicle or trailer, it can have its own engine for its full operation, it can be driven by the engine of these others, or a combined system of both. BACKGROUND OF THE INVENTION

The machines on the market and currently used to eliminate weeds are diverse, among others: Knapsack spraying machines, with manual pressure pump, hose and sprayer with lance. Electric backpack machines, using energy accumulators, hose and nozzle sprayer. Spraying machines, coupled in small handcarts, wheelbarrow type, with one or two front wheels, with a chassis or platform to support the different components and, at the back, two rods to direct it, and two feet on which it rests, and in other cases, front and rear wheels, with a handle, type handlebar to steer it, which have a built-in tank for liquids, an internal combustion engine, generally those that usually use gasoline or diesel fuels for their operation, propulsion pump of water, hose and sprayer with or without lance. And other spraying machines or equipment, coupled to tractors, quad, or other types of vehicles or coupled to trailers, which have tanks for liquids, explosion engines, or are powered by the tractor or motor vehicle engine itself. It is coupled, equipping liquid propellant pumps, hoses, with or without lance, and manual or automatic sprayers. Said machines, with the exception of some of these, which will be detailed later, are designed and prepared to use herbicides mixed with water, at room temperature, to eliminate weeds, and are also used to spray with phytosanitary products to combat diseases or plant pests.

There is a machine on the market, of Italian origin, that uses a system for spraying called Grass Killer, patented by the Caffini company, which is an equally ecological weed killer, which also uses water, without any type of herbicide , but at room temperature, and acts under high pressure on the roots of weeds, which has nothing to do with the present invention. There are also machines on the market that use a specific system of boiling water, which is called the HEATWEED METHOD. This patented system is based on the fact that the water is propelled by boiling between 99.2 ° C and 99.6 ⁰ in a stable way, being totally different from the present Utility Model, which can use the water at any temperature that is programmed, either 100 °, to 99, 9 ^or 99, 8 ° ..., etc., as room temperature, the proposed machine being compatible, also for spraying with phytosanitary products or other products.
