Caimán showed at AgroActiva 2024 (June 5-8 – Armstrong, Santa Fe) the first dual sprayer of Argentina, with a system of smart app incorporated as standard.
It’s about the model SP DSS (Dual Spray System), a state-of-the-art equipment that proposes a double spray system, with two tanks, two pumps and two independent spray circuits.
It comes equipped as standard with the modern One Smart Spray intelligent spray system, developed worldwide by Bosch and BASF.
“It is a machine that allows you to control, in the same pass, conventional spraying to make a pre-emergent, or a residual product and also make selective applications”synthesize Mario Roccifrom the Cayman Engineering Department.
“There is a main tank of 3,850 liters for conventional application and another of 1,000 liters for selective application”he adds.
“Two centrifugal pumps were also incorporated. A 650 liter/minute pump for conventional applications and another 450 liter/minute pump for selective applications, both with independent hydraulic control.”Explain Rocci.
“The One Smart Spray system is based on high-resolution and multispectral RGB cameras, as well as lights that allow you to work at night and in undergrowth shading situations”comments Rocci.
“For each camera there are three light boxes that emit near red and infrared. “So, we have the visible colors, with the RGB spectrum, and the other visualization possibilities”Add.
Bosch technology and BASF arrived at the Argentina with the algorithms for soy, cotton, sunflower and corn.
Thus, it can be applied to everything other than crops (identifying weeds) and with four degrees of sensitivity, to regulate applications, for example, in small or large sizes.
equipment
The Cayman sprayer SP DSS It has two independent spray circuits, equipped with nozzles TeeJet.
Both circuits have electric valves and allow peak-by-peak cutting, without overlap
Another peculiarity is that there is recirculation of water in the two channels to purge them and to be able to change the broths more quickly.
Both booms have electric valves and in the case of the selective one, they are PWM (pulse width modulation).
“As the valve lock is PWM, it allows us to be independent of the tractor engine speed and ensure homogeneous spraying at all times and across the entire working width”he points out Rocci.
Platform
In matters of Precision farming To manage applications, the sprayer SP DSS incorporates the platform e-Condeveloped by Caimán.
It allows data to be loaded to manage the two flow rates used and in the prescribed doses.
“Thus, in the conventional application we can apply a manual or variable dose with a prescription map, while in the selective application the platform has a device to indicate if we are going to do green on brown, fallow; or green on green, in established crops”expresses Rocci.
The sprayer SP DSS It will be in a testing period for the remainder of 2024, with the aim of being put into the commercial phase during 2025.
