DESCRIPTION

COMPLEMENTARY DEVICE FOR THE APPLICATION OF VARIOUS PRODUCTS

PHYTOSANITARY PRODUCTS BY THE SAME MACHINE

OBJECT OF THE INVENTION

The invention to which this report refers refers to a complementary device for the application of various phytosanitary products by the same machine in crop fields. This device would be attached to the general treatment machine and without changing the machine it would allow another treatment with another phytosanitary product.

FIELD OF THE INVENTION

The field of the invention is that of the agricultural machinery industry and especially the industry for the manufacture of machinery for the application of phytosanitary products.

BACKGROUND OF THE INVENTION

In the usual machines, the application of phytosanitary products is carried out by spraying a phytosanitary product made from a base liquid (usually water) on the cultivation surface, to which a certain amount of active material of one or more phytosanitary products is added. Resulting in a homogeneous mixture of "phytosanitary broth" that the sprayer or atomizer of the machine will distribute evenly in the field of cultivation.

If the farmer wants to carry out a treatment with another product only in some area of the plot, he must prepare another broth (with water and phytosanitary products), go back to the plot (with the compaction problems and damage to the crop that this entails). and treat only the determined area or treat the entire plot (at the same time as the other treatment or in another independent one) with the consequent expense of phytosanitary products, and therefore, of money and the consequent impact on the environment.

With the device proposed by the invention, any existing or new machine for applying phytosanitary products may be capable of carrying out two or more simultaneous treatments in certain areas, with only one base mixture.

There are precedents of spraying machines, whether manual, on vehicles or by means of aerial elements, but in no case does the inventor know of any machine capable of carrying and working with two or more phytosanitary products at the same time.

BRIEF DESCRIPTION OF THE INVENTION

The complementary device for the application of various phytosanitary products by the same machine has electronics and a CPU that fully monitors the sprayer or atomizer by installing pressure transducers in each of the sprayer or atomizer tracks. In this way, it knows the pressure at which the nozzles go and through a digital calibration process, it knows the flow rate of each of the nozzles, and when configuring it, it tells it how many nozzles each route has, so it can know exactly the total flow rate. of all the nozzles, the applied dose, etc...

In an attached system, secondary circuit, we have a pump that takes the 2nd phytosanitary product (active material) as a pure product. After the pump there is a pressure switch so that, once the set pressure is reached, the pump stops and restarts once the set pressure drops. Then there is a hydropneumatic accumulator to have a small volume of accumulation and that the pump is not starting and stopping all the time. The set pressure of this circuit must be higher than the normal working pressure of the sprayer or atomizer.

Then we have a flowmeter for very low flows and a precision stepper valve capable of controlling flows of around 0.1 l/min. All controlled by the CPU which in turn monitors the sprayer or atomizer.

Since the CPU knows from its monitoring sensors and GPS the real flow and the dose in l/ha of the mixture that is being applied, the operator can indicate the l/ha of active material of the second product that he wants to apply to the field.

Thus, the CPU calculates the instantaneous flow that the step-by-step valve (which it controls with the small flowmeter) must allow to pass so that the dose of active material of the second product is correct in l/ha, and it opens and closes said valve in function of vehicle speed, equipment pressure, etc.

If the operator closes or opens any path of the sprayer, as the system knows from its pressure sensors, the system will automatically adjust the rate to the lowest working width at that time.

Injection into the sprayer or atomizer is done after the pressure regulation valve of the sprayer

To activate or stop the injection of the second product, the operator can either do it manually by means of a button or switch, or the prescription map data can come from a drone, satellite, etc... or even from bad sensors. herbs, plant vigor, etc. shipped in the front part of the tractor, which can automatically activate or stop the injection of this second product.

Just as a second product can be added, by adding "circuits" of pump, accumulator, flow meter and valve step by step, a third, fourth, etc. could be added.

The system adapts to any existing atomizer or sprayer, and provides many advantages, such as higher production (we do not use phytosanitary products on the entire surface that affect the main crop but are necessary to control weeds genetically close to the main crop), less economic expense (you only have to spend money on phytosanitary products for specific areas, not for the entire plot) and less environmental impact (the second product is only applied in specific areas, not on the entire plot, and negative impacts are reduced)

PREFERRED EMBODIMENT OF THE INVENTION.

The invention refers to a complementary device for the application of various phytosanitary products by the same machine in crop fields. This device would be attached to the general treatment machine and would allow another treatment with another phytosanitary product without changing the machine.

Preferably, the device is mounted on a phytosanitary product application machine made up of a main circuit (3) made up of a main tank (3.1) where the phytosanitary product to be applied dissolved with water is located, followed by a pump pressure (3.2), followed by a regulating valve (3.3), which then passes the liquid through a flow meter (3.4), a manometer (3.5), some pressure translators (2) with sensors (7) and distributing the sprayed liquid (5) by means of various nozzles (4).

The secondary circuit (6) object of the invention is made up from a product tank (6.1) as pure product, followed by a pump (6.2), after the pump there is a pressure switch (6.7) so that once the reaches the set pressure stops the pump and restart once the set pressure drops. Then there is a hydropneumatic accumulator (6.4) to have a small volume of accumulation and that the pump is not starting and stopping all the time. The set pressure of this circuit must be higher than the normal working pressure of the sprayer or atomizer.

The next element of the circuit is a flow meter (6.5) for very low flows and a precision step-by-step regulating valve (6.6) capable of controlling flows of around 0.1 l/min. It is incorporated into the main circuit (3) where by means of the pressure sensors (7) they indicate to the sprayer/atomizer (8) the flow rate of sprayed liquid (5) and the dose to be applied through the nozzles (4).

The two systems are controlled by the CPU (1), which monitors all the operations with the information in real time that it receives from all the elements of the system.

At an operational level, since the CPU (1) knows from its monitoring sensors (7) and GPS the real flow and the dose in l/ha of the mixture that is being applied, the operator can indicate the l/ha of active matter of the second product that you want to apply to the field.

Thus, the CPU (1) calculates the instantaneous flow that the step-by-step valve (6.6) must allow to pass so that the dose of active material of the second product is correct in l/ha and opens and closes said valve depending on the the speed of the vehicle where the two main (3) and secondary (6) circuits are located.

If the operator closes or opens any path of the sprayer (8), as the system knows with its pressure sensors (7), the system will automatically adjust the dose to the lowest working width at that moment.

Injection into the sprayer/atomizer (8) is done after the pressure regulation valve of the sprayer

To activate or stop the injection of the second product, the operator can either do it manually using a switch button (6.3), based on a visual inspection, or based on the data obtained through prescription maps from a drone, satellite or including weed sensors, plant vigor,

Once the nature of the invention has been sufficiently described, as well as the manner of putting it into practice, it must be noted that the provisions indicated above and represented in the attached drawings are subject to detailed modifications as long as they do not alter their fundamental principles, established in paragraphs above and summarized in the following claims.
