Abstract
The invention relates to a device for preparing aqueous solutions intended to be sprayed via a manifold including two or more nozzle sections, on a surface from a mixture of water and two or more additives. Said device includes: —a water vessel (2); —a pump (6) connected to each section (4, 5); —a first pipe (8) connecting the water vessel (2) to the pump (6); —a second pipe (9) with as many parallel arms between the pump (6) and each section (4, 5); —at least two additive vessels (10, 11); and—a means (12) for metering the amount of each additive that is to be injected into the second pipe (9) and mixed with the water.
Claims12
A device for preparing one, two or more aqueous solutions intended to be sprayed simultaneously or alternatively, using a spray nozzle boom comprised of several boom sections (4, 5) connected in series or in parallel, on a surface such as a cultivated soil, from a mixture of water and of two, three or more additive products, the device comprising:
- a main water tank (2);
- a pump (6) adapted to be connected to each boom section of the spray nozzle boom;
- a first pipe (8) connecting the water tank (2) to said pump (6);
- a second pipe (9) dividing into as many parallel branches connecting an outlet of said pump (6) to each boom section of the spray nozzle boom (4,5) and provided at each branch with a check valve (49,50) followed by an injection point (44,45);
- at least two additive product tanks (10,11), each containing different additive products;
- means (12) for metering an amount of each additive product to be injected into the second pipe (9) to be mixed with water,
- wherein said means (12) carry out successive batches of different premixtures of water and additive products, wherein each premixture corresponds to an amount of additive products, and wherein said device comprises two, three or more buffer tanks (29,30) adapted to each receive successive premixture batches, and an output of which is connected for each one to a pump (32,35) and then to the injection points (44,45) of the branches of the second pipe (9) in order to be able to supply one or more boom sections with premixture so that these premixtures may be different according to one of more boom sections in which they will be injected on the one hand, that they are dosage-modulated in order to obtain on each boom section an ad hoc concentration of additive products in accordance with a predetermined concentration on the other hand, and finally that, after an addition of water to the different premixtures, a constant spray pressure is obtained on each boom section.
