4FZ-30型自走式番茄收获机的研制

为了适应加工番茄的大面积采收,该文设计了一种适用于加工番茄的自走式收获机,并阐述了该机的总体结构及切割捡拾装置、分离装置和色选装置三大核心工作部件的工作原理,并进行了田间试验。试验结果表明,在地形平坦,土壤绝对含水率为18%,番茄成熟度为98%的情况下,该机平均生产率为0.26%hm2/h,平均损失率为4.36%,平均破损率为4.10%,平均含杂率为3.09%,各项指标均达到行业标准NY/T1824-2009,满足设计要求。该研究为推动番茄收获机的国产化进程奠定了基础。

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.
