“…In their study, they declared that the amount of pesticide per unit agricultural area with low margin error and commercialization of this technology. Ilıca and Boz [2] developed an agricultural nozzle-height control test system using a permanent magnet tubular linear synchronous motor. They experimentally tested this control system that the developed system keeps the distance between differently sized plants and the nozzle at the set point with minimum error.…”

The optimum design for effective and economical use of agricultural sprayer machinery is becoming increasingly important. In order to reduce weight of agricultural sprayer machinery, safe designing has been continuously developed on chassis and sprayer boom by related engineers. In this study, the stress strain analyses of the developed mounted type chassis design for agricultural sprayer machine were carried out with finite elements analyses (FEA) after doing related literature survey. The Taguchi orthogonal array design (L16, 24) for eight FEA is done. After doing systematically static FEA according to Taguchi experimental design, von-Mises stress and shear stress together with displacements on mounted type chassis were obtained. As a result, the effect of the weights of pesticide tank and sprayer boom on stresses and displacement determined. Moreover, the theoretical information about mounting boom width and safety factor on the developed chassis predicted via FEA before manufacturing.

“…Compared with the general agricultural machinery, the sprayer has complicated operating conditions and needs to be equipped with a special suspension system to improve its ride comfort, reduce the vibration, swing and rotation of the sprayer boom, thereby making the spray more uniform and reduce drift (Herbst A. et al, 2018;Ilica A. et al, 2018;Gil E. et al, 2015). Air suspension is widely used in sprayers because of its good nonlinear elastic characteristics, large suspension range, adjustable load capacity, and large loadbearing mass (Melzi S. et al, 2014;Chen Y. et al, 2016).…”

When a sprayer travels on a ramp or a rough road, the load exerted on each wheel changes. If an unbalanced wheel load is maintained for long periods of time, the wheels may slip, the sprayer’s manoeuvrability is affected, and a rollover accident may occur. In this study, the air suspension of a self-propelled sprayer chassis was investigated, and the potential load imbalance conditions of the sprayer suspension were analysed. A mathematical model of the inflation/deflation of the suspension was established based on air nonlinear thermodynamics and vertical dynamics theory and a ¼-scale vertical dynamics model of the sprayer chassis was developed. A control strategy to balance the sprayer’s wheel load was developed. Considering the nonlinear characteristics of the air suspension, a sliding mode variable structure control method was used to balance the wheel load. Simulation experiments were conducted under different working conditions. The simulation results showed that the sliding mode variable structure control provided good control response and precision. The proposed auto load-levelling controller was tested under different working conditions, including different roll and pitch angles and navigating a rough road; the controller successfully changed the load on each spring to ensure that the sprung mass of the suspension was equal and the wheel load was balanced. The results of this study provide reference information for auto load-levelling control of large sprayers.

“…An increase in the world population triggers the rise of needs to meet the demands in agricultural production. The use of pesticides is inevitable for high efficiency in agricultural production [1]. The fact that agricultural areas are limited, and agricultural trade has a large share in the domestic economies of nations has revealed the concept of sensitive agriculture.…”

Some improvements are needed in spraying with orchard sprayers. During the spraying process, it is also applied in the spaces between trees of cases where the tree spacing is high. For this reason, extra pesticides are consumed and harmful substances are added to the soil. Thus, the production costs increase and efficiency decreases, and also pesticide residues transferred from soil to crops cause health problems. In this study, ultrasonic sensors are placed on the right and left surfaces of the machine facing the tree. With the help of these sensors, the pesticides are sprayed as long as an object is detected within a certain distance. Spraying is stopped when the object is not detected, and this operation is carried out automatically. The developed system consists of an electronic control unit, solenoid valves, and ultrasonic sensors, controlled by a microcontroller. Thanks to this automatic control system, high rates of savings are achieved in pesticide consumption and the addition of harmful substances to the soil is prevented. In addition, thanks to the its compact structure, it can be easily mounted on existing sprayers that are controlled manually.
