Since the agricultural machinery itself has various forms, complex structures and works in poor conditions, so it has many special requirements for hydraulic components, such as lower price and high reliability. The requirements of agricultural machinery for hydraulic technology are mainly as the followings.
The power of China's agricultural machinery has reached 450 million kilowatts. The application of energy-saving technology can not only optimize the performance of the main engine and reduce environmental pollution, but also save 4.5 million kilowatts of power for every reduction in energy consumption. This huge social and economic benefits attract many scientific and technological personnel to invest huge energy and intelligence to achieve many results and progress.
The hydrostatic drive device can be continuously variable, with high power, wide speed range and good low speed stability. It is especially suitable for agricultural machinery with diversified structures and low speed.
The hydrostatic drive combine harvester has higher working efficiency and less auxiliary working time than the mechanical drive combine harvester, and the work efficiency is increased by 10-30%, which is 1-2% higher than the mechanical drive combine harvester. This kind of agricultural machinery is not only convenient and comfortable to operate, but also easy to maintain and has a low failure rate. At present, 30% of failures of domestically-made mechanical drive combine harvesters are caused by gearboxes.
The hydrostatically driven combine harvester allows the engine to work under objective conditions. It not only ensures the constant speed of other components, but also has an excellent minimum stable driving speed. It is suitable for harvesting high-yield crops and lodging crops. However, the more productive the mechanical drive combine harvester, the more likely it is to block. What brings farmers is not the joy of the harvest, but unnecessary mental damage.
Leakage, noise and other faults are persistent problems in the hydraulic industry and are also important factors limiting the application of hydraulic technology. At present, the non-leakage technology in hydraulic technology will be widely used, including the development of new pipe joint components, threaded cartridge valves, combined seals, and hydraulic system pollution control technology. The gradual promotion of these common technologies plays an important role in improving the performance of agricultural machinery.
The application prospect of hydraulic technology in agricultural machinery is very broad, and the hydraulic technology will be widely used in the following agricultural machinery.
(1) New-type high-horsepower tractors and their working tools, such as tillage tools, precision seeders, tractors with high ground clearance, and supporting tools.
(2) Agricultural basic construction machinery: canal gate building machinery, gate opening and closing machine, trencher, dredging machine, loader, tractor, grader.
(3) Large-scale plant protection machinery: high ground clearance wide rod sprayer, translational sprinkler irrigation machine, etc.
(4) High-yield crop cultivation and harvesting machinery: wheat, corn, cotton intercropping machinery, rice harvesting machinery, high-speed inserting machine.
(5) Agricultural robots, facility agricultural robots, manipulators and complete sets of automation equipment: precision agricultural work tools, intelligent planters, fertilizer spreaders and plant protection machinery.
(6) Agricultural and forestry work tools: drilling machines, forestry tractors, timber handling machines.
(7) Fishery machinery: net-opening machine, hoisting machine, dry ice making machine.
(8) Agricultural transport machinery: multifunctional agricultural vehicles.
(9) Animal husbandry machinery: forage harvester, feed pelletizer, high-density baler.
(10) Economic crop machinery: cotton harvester, fruit harvester, potato, sweet potato, sugar beet, sugar cane harvester, high ground reed harvester, peanut, vegetable oil harvester.
