In recent years, due to urgent need of potato production, a plurality of scientific research units and production enterprises develop potato segmental harvesting machines and combined harvesting machines in China successively.
However, during the mechanized harvesting of potatoes, the problem of tuber damage severely reduces the quality of the seed potatoes, the appearance and the intrinsic quality of the commercial potatoes. Because the domestic potato variety has low crashworthiness, the harvested potatoes have high fresh food ratio and low production and processing ratio, the commercial department puts high requirements on the mechanical harvesting quality and storage conditions of the finished fresh potatoes. Most of the existing potato diggers and combine harvesters adopt a multi-stage shaking type chain separating device so as to reduce the impurity rate of potatoes. However, during the harvesting process, the potato skins are easily damaged due to the collision between the potatoes and the conveying rods of the separating device and the collision between the potatoes and tubers, and the skins are damaged more and more as the number and the spacing of the separation stages are longer. The qualification rate and the quality of the product are greatly reduced, and the requirements of fresh potato storage conditions cannot be met. The quality of the primary processed potato products and the potato convenience food industry are affected, and the economic benefit of the whole potato processing industry is affected. Therefore, research and improvement of potato harvesters and reduction of damage of potato tubers are of great significance in ensuring continuous, efficient and healthy development of the potato industry.
