Corn Thresher is a multi-functional agricultural machinery and equipment. When we encounter hard soil mines, we can be equipped with related rotary tillers to loosen the soil first. Lubricants play a very important role in equipment:
　　 (1) Cooling and heat dissipation. Prevent the temperature of the parts of the pastoral management machine from rising due to friction and heat, resulting in adhesive wear, aggravation of corrosion and abrasion, and even burning of the pastoral management machine's rubber seals or bearings.
　　 (2) Sealing protection. Lubricating grease can effectively isolate the moisture, oxygen and some harmful media erosion in the humid air, and can also prevent the leakage of the internal media of the pastoral management machine. The grease can also prevent water, dust, and impurities from entering the friction pair.
　　 (3) The effect of washing dirt. When the friction pair is in motion, abrasive particles will be generated, as well as external impurities, dust and sand, etc., will aggravate the wear of the friction surface. Forced liquid circulation lubrication can take away the abrasive particles, reducing or avoiding the wear of the pastoral management machine.
　　 (4) Reduce friction and wear. Because the lubricating film can reduce the friction factor between the two moving parts, it will reduce the wear and consumption of the parts, and at the same time can play a damping and vibration absorption effect, thereby extending the life of the Manual Seeder, reducing power consumption, and improving the operating characteristics of the field management machine.
