Research progress of metal detection system for feed harvesters
During the operation of the feed harvester,metal objects such as iron wires left in the field can easily mix with the grass and cause damage to machine components.The increase in maintenance time can easily miss the optimal harvesting time for grass,and the subsequent consumption of mixed metal grass by livestock can pose a serious threat to their gastrointestinal health.Therefore,equipping high-performance metal detection device is gradually becoming an essential system for feed harvesting machinery.Currently,most feed harvesting machinery produced by foreign manufacturers are equipped with metal detection devices,but the models produced by domestic manufacturers are rarely equipped with such devices,and the stability and sensitivity of related performance also have a significant gap compared to foreign products.Through literature review,the demand for metal detection devices in feed harvesters was analyzed,and the principle of metal detection technology was briefly described.The application and development of metal detection technology in feed harvesters at home and abroad were compared and analyzed.In view of the current technical challenges and trends in domestic metal detection,such as system sensitivity,integration,system response time and braking control strategy,suggestions are proposed to accelerate the research and development,testing,and promotion of metal detection systems in the future,and to overcome the bottleneck problem of the core key system of feed harvesting machinery in China.
