III - MAIN OBJECTIVE

For this purpose, the present invention consists of a pumping and control system for the application of liquid products (water and liquid fertilizers) to agricultural soils. For this, there is a pump driven by a hydraulic motor that circulates both the water and the products to be applied.

The object has the appropriate water and chemical inputs that the operator can choose so that said fluid is delivered to the distribution system.

[0022] The distribution system allows the introduction of liquid products at the same time and place as sowing. For this, the appropriate distribution system hoses are added to the seeder blades that pierce the soil and allow the seeding.

[0023] The distribution system is controlled by | computerized control system which regulates the pressure and flow of liquid delivered through its corresponding valves, allowing the operator to modify such parameters via the computerized control console (separate from the module). This includes on the front of the main module a digital display showing pump speed, a gauge showing pressure and the possibility of a pump bleed.

In addition, it has the possibility of adding a stirring tank that keeps the liquids correctly mixed.

IV - DETAILED DESCRIPTION OF THE PROPOSED OBJECT

[0025] The main object is contained in a stainless steel cabinet (v).

Separately, the computerized control console is connected to the module sensors using the corresponding cables. This should be located at the operator's preferred location.

From the graphs presented at the end of the present document, the following arrangement of the components of the invention can be seen: FRONT (According to FIGURE 1).

The front of the object is molded with a stepped gap that separates the lower front part from the upper one.

[0030] In the lower left is the source tank selector valve (e) and in the lower right is the purge / qperation function selector valve (f).

At the upper right, the vent hole (d) is located next to the pressure gauge (c). At the upper center, the digital pump speed display (b) is positioned. At the top left is the suction filter (a) that is connected to the rear through some hoses. This rear access is possible due to a triangular liming on the front of the case.

BACK (According to FIGURE 2).

At the top are the connections from the front of the module: the bleed port hose (d), q pressure gauge tube (c), digital pump speed display cables (b) and the suction filter hoses (a).

[0034] On the right center part, the piston diaphragm pump (g) connected to the hydraulic motor (i) is mounted and above it the hydraulic flow control block (h) with the inlets and outlets for connection to the hydraulic system. existing. Adjacent to the pump is the pressure relief valve (o) from which the pressure relief valve outlet (p) is released. In the center of the object is installed the electro-hydraulic servo valve (m) the stirring tap (k). On the left side are the check valve (I), the check valve (n) and the controlled fluid outlet (q).

At the bottom, the servo valve bypass outlet (r), the purge valve outlet (s), the chemical tank suction port (t) are positioned from the left (to the right) and the suction orifice of the water tank (u), respectively.

V - OPERATION OF THE ASSEMBLY

[0036] The module is contained in a stainless steel enclosure (v) to secure and secure internal components.

[0037] A positive displacement piston diaphragm pump (g) circulates the liquid. This pump (g) is driven by a hydraulic motor (i) at a constant speed whose maximum value is set by the hydraulic flow control block (h).

[0038] The digital pump speed display (b) shows the machine operator the updated pump speed.

[0039] The pressure gauge (c) shows the machine operator the value of the liquid pressure at the pump outlet.

Pump driven liquid (g) flows through a hose to the electro-hydraulic servo valve (m) and also to the stirring tap (k).

This stirring tap (k) may be connected to a tank containing chemicals and providing a flow that allows the contents of the tank to be agitated.

[0042] An important component is the computerized control system that receives information on the amount of liquid flowing from the flowmeter (j). Thus, the computerized control system sends electrical signals to the electro-hydraulic servo valve ( m) to vary the pressure as required.

The shut-off solenoid valve (n) opens or closes according to signals sent by the computerized control system to allow or prevent the flow of liquid to the distribution system through the controlled fluid outlet (q).

The controlled fluid output (q) is monitored by this computerized control system which interfaces with the computerized control console.

Through the console, the operator can vary the flow, pressure, frequency of application of products and other parameters according to the requirements of each particular situation.

In this controlled fluid outlet (q) are connected the distribution system hoses through which the liquids circulate until they reach the sower blades that insert the seed in the soil and allow the application of the liquid products at that same instant.

[0047] The source tank selector valve (e) allows the machine operator to switch between two tanks so that one of these is the source of liquid flowing through the pump. The two tanks are connected to the module by separate hoses that are connected to the chemical tank suction port (t) and the water tank suction port (u).

[0048] The Purge / Function (f) selector valve allows the machine operator to decide whether the flow derived from the electro-hydraulic servo valve (m) is returned (via a hose) to the chemical tank through servo valve bypass outlet (r) or is directed to the ground through the purge valve outlet (s).

[0049] The bleed port (d) allows the operator to connect an external pump to circulate water through the manifold that is connected to the controlled fluid outlet (q) to clean said manifold. The non-return valve (I) prevents liquid from escaping through the bleed port (d).

[0050] The pressure relief valve (o) opens to protect the machine if the pressure is too high. In such cases, liquid exits the system through the pressure relief valve outlet (p). Said is normally connected via a hose to the chemical tank.

Having thus specifically described and determined the nature of the present invention and how it may be carried out, the following is claimed as the sole right and property.
