Development of a motorized granular applicator of agrochemicals for coffee trees
A motorized granular applicator was developed for the coffee plantations located in sloping areas or planted in high plant density systems in Brazil. The equipment developed is a walk behind tractor powered by a 3.73 kW engine, having a ten-litre hopper with a 'Horshire Farmery' type metering device and screw conveyor impelled by a land wheel. Evaluations of the prototype were carried out in a field test applying triadimenol granular fungicide comparing with a tractor powered and a horse drawn equipment, as well as recording the forward speed and the turning time of the equipment. The estimated overall working rate of the prototype was slightly higher than the tractor powered and lower than the horse drawn equipment. The manoeuvrability of the prototype was fairly good, allowing very quick turning time. It is concluded that the prototype of granular applicator achieved the proposed goals considering the level of control of coffee leaf rust compared to other commercial equipment and presented overallwork rate similar to tractor powered granular applicator.
