The rice transplanter is indispensable in the rice planting process, and therefore, the maintenance of the rice transplanter becomes very important. Under the condition of proper maintenance, the service life of the agricultural machine can be extended and the working efficiency can be improved. 1. Check engine oil level, hydraulic oil level, and fuel tank oil level. If insufficient, add in enough time. 2. Every day when the work is done, the rice transplanter should be opened to the shore and the mud on the rice transplanter should be cleaned. 3. Replace the engine oil. Replace the engine oil for rice transplanters that have been used in season or for more than 50 hours. 4. Put all the moving parts, screws, and metal parts on the rice transplanter before putting them into the warehouse and apply rust and rust to each handle. 5. Check and adjust the main clutch handle pull wire, lifting handle wire, puller pull wire and steering clutch pull wire clearance and sensitivity. At the same time, drip a few drops of oil in these wire holes to increase flexibility. Functional oligosaccharides refer to oligosaccharides that are difficult or impossible to be digested and absorbed by the human body and have special physiological effects on the human body. Its sweetness is generally only 30-50% of that of sucrose, and it has physiological functions such as low-calorie, anti-caries, prevention and treatment of diabetes, and improvement of intestinal colony structure. Due to the special physiological functions of functional oligosaccharides, it becomes a nutrient and health care product. A new generation of food-effect raw materials that integrate diet and therapy. It is a new functional sugar source that replaces sucrose and has a wide range of uses and application prospects. Common functional oligosaccharides include: xylo-oligosaccharides, fructooligosaccharides, galacto-oligosaccharides, isomaltose, raffinose and so on.
