Development of 4FZ-30 self-propelled tomato harvester

To adapt to harvesting the processing tomato’s in a large area, a self-propelled harvester for processing tomato was designed. The overall structure and the working principle of three core parts of a self-propelled harvester were described, which was composed of cutting-picking device, separation devices, and color sorting device. The field experiment was conducted. The results showed that when the terrain was flat, the absolute moisture content of soil was 18% and maturity of tomato was 98%, the machine’s average productivity was 0.26hm2/h, average loss rate was 4.36%, average damage rate was 4.10% and average impurity rate was 3.09%. Every indicator of the harvester was accord with industry standards NY/T1824-2009. This research lays a foundation of accelerating process of localization research of tomato harvester.
