BRIEF DESCRIPTION OF THE INVENTION

[0014]

[0011] The present invention relates to a spraying machine (1) designed for applying spray solution to agricultural fields. The main innovation of this machine lies in its ability to recover the spray solution that does not adhere to the plants during the spraying process, thus preventing its loss and drift caused by the wind. This is achieved by means of a sprinkler system (G) that applies coarse droplets, with adjustable heads for a high level of wetting. The solution exits a main container (A), passing first through a filter (D) located in the hose (E) that leads to the sprinkler system (G). Each spraying machine (1) is equipped with a recovery and filter tank (K) for the spray solution.

[0015]

[0012] The present invention also comprises a system consisting of two spraying machines (1) that operate jointly and in sync and that move in parallel along the crop lines, allowing the application of the solution from both sides of the plants.

[0022] DETAILED DESCRIPTION OF THE INVENTION

[0023]

[0018] The present invention relates to a spraying machine (1) designed for the efficient application of spray solution in agricultural fields. The spraying machine (1) is characterized by an innovative system that allows the recovery of spray solution not adhering to the plants during the spraying process, optimizing both application efficiency and reducing environmental pollution and improving the economics of the agricultural process. This machine is characterized by comprising a main container (A) that stores the spray solution to be applied, a motor (not shown) that feeds the solution through a hose (E) to a sprinkler system (G), after first passing through a filter attached to the motor outlet to block the exit of any solid particles.

[0024]

[0019] The spraying machine (1) comprises a recovery and filtering tank (K) that is completely covered by a cover (L), which allows for the recovery of the maximum amount of spray solution not adhering to the plants. The recovery and filtering tank (K) has a tilt regulator (I) and a support hinge (J) that allows for adjusting the tilt angle necessary to facilitate spray solution recovery. The recovered spray solution falls into the base of the tank (K), where a filter mesh (N) separates the reusable spray solution from solid waste. The solution is transferred through a hose (O) to a recovered spray solution container (Q), which has vents (R) to equalize pressure and ensure the correct operation of the return pump (V).A level indicator (S) in the recovered broth container determines when the return pump (V) is switched on, which transfers the recovered broth back to the main container (A), thus closing a continuous recirculation cycle.

[0025]

[0020] In addition, the spraying machine (1) includes a filter (D) in the middle of the broth feed hose (E) that prevents solid particles from entering the sprinkler system (G), and transfers the product from the main container (A) to the distributor tube (F) of the sprinkler system (G) which has orientable heads and shut-off valves (X).

[0026]

[0021] The spraying machine (1) also has a structure (H) that supports the recovery and filtering tub (K) and comprises a tilt regulator (I) and support hinges (J) to adjust the tilt of the tub (K), which recovers and filters the broth sprayed by the other spraying machine (1) working in parallel, which is then transferred by a hose (O) to the recovered broth container (Q).

[0027]

[0022] As shown in Figure 1, the spraying machine (1) includes several components. The main container (A) is where the spray solution is stored, with a capacity appropriate to the specific needs of the field. This container is connected to a motor (not shown), which directs the solution to the sprinkler system (G). This motor is connected to a distributor pipe (F) that supports the sprinkler system (G). The spraying machine (1) also comprises a recovery and filtering tank (K) lined with a cover (L) that has a filter mesh (N) to aid in solution recovery, and a container for the recovered solution (Q).

[0028]

[0023] The motor is coupled with a filter that blocks any solid particles present in the solution inside the main container (A). From this filter, the solution is transferred via a hose (E) to the sprinkler system (G). This hose (E) is compatible with the type of product used in the solution and is capable of withstanding the selected working pressure. It connects to the distributor pipe (F) of the sprinkler system (G).

[0029]

[0024] The broth recovery and filtering tank (K) is equipped with a tilt regulator (I) and support hinges (J) that allow the angle of the recovery and filtering tank (K) to be adjusted to suit the angle of the plant structure. It also has a flexible structure (M) that allows it to be moved close to the plant without being damaged by impacts.

[0025] As shown in Figure 2, the recovery and filtering tank (K) is lined with a cover (L) that aids in broth recovery and has a filter mesh (N) at its base that filters the recovered broth, preventing the entry of solid particles. The filtered broth passes through a hose (O) to the recovered broth container (Q).

[0030]

[0026] As illustrated in Figure 3, the sprinkler system (G) is connected to the crop feed hose (E) from the main container (A) to a distributor pipe (F) of the sprinkler system (G), which distributes the solution to the sprinklers (G), allowing precise application of the solution to the plants. In one embodiment of the invention, the sprinklers (G) can be showers that spray coarse droplets of solution.

[0031]

[0027] The broth recovered from the recovery and filtration tank (K) is transferred via a hose (O) to the recovered broth container (Q) (Fig. 1). This container (Q) is designed with vents (R) to allow for pressure equalization and proper operation of the return pump (V). It also includes a recovered broth level indicator (S), which helps determine when to activate the return pump (V). An electronic or electromechanical level switch can also be installed to automate the operation of the return pump (V).

[0032]

[0028] Figure 4 details the spray solution recovery cycle. The return pump (V) can be electric, conditioned to the tractor's voltage, hydraulic, or any other suitable type. This return pump (V) transfers the recovered solution from the recovered solution container (Q) back to the main container (A) via a hose (W), thus completing the reprocessing and application cycle.

[0029] Figure 4 also shows how the two sprayers (1) operate in parallel along the crop rows. This design allows the solution to be applied from both sides of the plants, ensuring complete coverage and maximum recovery of the unadhered solution.

[0033]

[0030] Figure 5 details the sprinkler (shower) system (G), showing the hose (E) that feeds the solution from the main container (A) to a distribution pipe (F) of the sprinkler system (G), which distributes the solution to the sprinklers (showers) (G). These sprinklers have adjustable heads and shut-off valves (X).

[0034]

[0031] As can be seen from the description and accompanying figures, the present invention introduces an innovative spraying machine (1) that not only applies the spray solution effectively but also recovers the spray solution that does not adhere to the plant, contributing to the economy and sustainability of the agricultural process. This invention represents a significant advance in agricultural application technology, offering a complete and efficient solution for farmers.
