- Based on the agronomic requirements and topographical characteristics of potato planting in the northwest arid region, the overall design scheme of the whole machine is determined. The key components are designed and analyzed by SOLID2019 3D software and a dynamic analysis model. The structure and working parameters of the split-type digging device, composite separation and lifting device, the film and vine clearing device, the picking platforms with different paths, the ton bag self-unloading platform, and the electrical lifting device were determined, which improved the potato harvesting quality and the reliability and adaptability of the key components.
- Field experiments have shown that the loss rate of the wheeled-chassis potato combine harvester with integrated bagging and ton bag-lifting systems is 2.1%, the potato damage rate is 1.7%, the skin breaking rate is 2.5%, the impurity content is 1.9%, and the productivity is about 0.15~0.23 hm2/h. The field performance test indicators all meet the national and industry standards requirements. The potato harvesting machine described in this article has a high degree of mechanization and good harvesting performance, which effectively improves work efficiency and saves a lot of labor costs, playing a good role in promoting the development of the potato industry in the arid areas of Northwest China.
