Successful development of a peanut pickup combine harvester, the first eight-row model in China
To meet the needs of industrial development and reverse as soon as possible the situation in which large, high-efficiency peanut harvesting equipment depends on imports, the Institute of Agricultural Mechanization of the Chinese Academy of Agricultural Sciences has continued to innovate. After successfully creating the world's first four-row semi-feeding peanut combine harvester, it recently succeeded in creating China's first eight-row peanut pickup combine harvester, filling a gap in this technical field in China.
The equipment is mainly composed of a wheeled self-propelled chassis, pickup system, conveying system, pod-picking system, cleaning system, pod-collecting system and electro-mechanical-hydraulic control system. It can complete 8-row peanut pickup, pod picking, cleaning and pod collecting in one pass as combined harvesting operations, with production efficiency reaching 12 mu per hour. Field production trials in Siyang, Jiangsu and other places showed that the overall technical route and process flow of the equipment are feasible, and the links of pickup, conveying, pod picking, straw discharge, cleaning and pod collecting are smooth and reliable, with good working performance. Its production efficiency is 5 to 6 times that of a two-row semi-feeding peanut combine harvester. Whether ridge planting or flat planting, whether dry vines or fresh vines, whether harvesting along the rows or across the rows, it can achieve smooth operation and has good adaptability.
⟦NL> It is understood that peanut is China's high-quality and advantageous oil crop with the strongest international competitiveness, with a perennial planting area of more than 70 million mu. With the rapid growth of peanut planting area in Xinjiang and Northeast China and the development of large-scale production in traditional production areas, domestic demand for high-efficiency peanut mechanized harvesting technology and equipment is becoming increasingly urgent. Eight-row peanut pickup combine harvesting equipment has a complex structure and high technical difficulty, and represents the development direction of today's high-efficiency peanut combine harvesting technology. After industrialization is achieved, it will certainly play an important role in meeting China's demand for high-efficiency and diversified peanut mechanized harvesting equipment, breaking the United States' monopoly on peanut pickup combine harvesting technology, and promoting the healthy development of China's peanut industry.
