Abstract
Agricultural machinery is the key fi eld in modern scientifi c and technological innovation. In recent years, China has made great achievements in the development of high-performance intelligent agricultural machinery with cutting-edge technology, which promotes the effi cient use of agricultural resources and environment-friendly development, and supports 70 percent of China’s agricultural mechanization production. This paper mainly focus on the innovation and progress in the fi eld of intelligent agricultural equipment technology in China from the aspects of information perception and precision production monitoring technology, intelligent operation management technologies, power machinery, farmland operation machinery, intelligent harvesting technology, production technology and agricultural products processing equipment. the paper also summarizes that, in the future, green, intelligence and universality will become the main characteristics of the development of intelligent agricultural machinery technology, and cross integration, extension and expansion will become the main direction of technological innovation. At last by referring to the application basis and cutting-edge technology of China’s intelligent agricultural machinery industry, the innovation and development goals and research direction of future intelligent agricultural equipment, the scientifi c and technological innovation and industrial development trend in the fi eld of agricultural mechanization and intelligent application integration, this paper puts forward some suggestions on the research direction of future intelligent agricultural equipment.
Highlights
In developing high-performance intelligent agricultural machinery with cutting-edge science and technology, China has developed agricultural machinery that is applicable in featured areas and crops and animal husbandry, developed small-scale agricultural machinery that finishes the whole production chain of tillage, seeding, planting, pesticide application, harvesting, storage and processing, and has realized whole process monitoring and regulation over production environment, process and operation quality, and has enhanced the application level of water, fertilizer and medicine and agricultural production capacity and efficiency, promoted efficient application of agricultural resources and environmental friendly development, and supported 70% of mechanized agricultural production in China [1]
Focusing on agricultural lean production, China has developed soil environmental information such as soil moisture, temperature, water potential, tillage resistance, as well as sowing amount, fertilization amount, rice and wheat growth, crop yield and sensors for lean production information, and formed a lean production regulation system based on crop production process and realized the controlling and regulation of more than 70% key parameters
China plans to make an overall planning of the innovation chain from application foundation to application demonstration, as well as the industrial chain of R&D, design, manufacturing, and service, and the entire agricultural and rural chain of grain economics and feeding, planting, breeding and processing, production and ecological life, with integration between agricultural machinery and agronomy, equipment and information, manufacturing and services, and production and ecology as the main paths
Summary
China has made breakthrough in the key technologies of the combine harvester’s intelligent working condition parameter control, high-efficiency and low-loss harvesting, high-throughput threshing and cleaning, and developed an intelligent and efficient rice-wheat combine harvester with a feed rate of over 10 kg/s. China has made breakthrough in the key components such as corn plant cutting, low-loss ear picking, high moisture content kernel after low loss threshing, as well as intelligent control of working conditions based on loss rate, and developed corn grain harvester with single/double longitudinal axial flow, corn ear and stem harvesters, corn ear combine harvesters, fresh corn combine harvesters, and realized corn damage rate of less than 4% with a corn moisture content of about 30%. China has made breakthrough in technologies such as automatic alignment, online production measurement, and working condition monitoring, integrated intelligent control system for cotton picking, and developed a sixrow cotton box-type and packaged high-efficiency intelligent cotton picker. China has developed technologies such as efficient stalk cutting, low-loss transportation, and stalk-leaf separation, and integrated intelligent control technologies such as alignment and cutting depth, and developed a wheeled/track type sugarcane combine harvester, studied key technologies and devices for the intelligent and low-loss rape harvesting, and developed self-propelled rape combine harvester and rape swathing and picking harvester, reducing total loss rate by about 6%; studied the technologies of drag reduction excavation, separation of fruit and soil, and high-efficiency fruit removal and cleaning, and developed high-efficiency self-propelled peanut combine harvesters and harvesters for digging and laying, picking and fruit removal, reducing total loss rate by about 4% [6,7]
