What aspects are mainly inspected in the natural safety hazard investigation of agricultural machinery during the midday season?

Agricultural machinery safety inspections are mainly conducted from four aspects: mechanical components, electrical systems, fuel systems, and human-machine safety. First, the mechanical components of the agricultural machinery are inspected. The mechanical components are the core of the agricultural machinery, and it is necessary to check the transmission system, blades, and cutting parts to ensure they operate normally without looseness, wear, or breakage; also check the lubrication system and cooling system to ensure normal operation. The electrical system of agricultural machinery is the power source for operation. It is necessary to check wires, plugs, and connections to ensure there is no damage, aging, or poor contact; also check electrical equipment and protective devices to ensure they work properly. The fuel system of agricultural machinery requires focused inspection. It is necessary to check the fuel tank, fuel lines, and fuel injectors to ensure there is no damage, leakage, or blockage; also check for fuel leaks and fire prevention facilities to ensure compliance with safety requirements. Finally, the human-machine safety of agricultural machinery is inspected. It is necessary to check the operator's console and seat to ensure they meet ergonomic requirements; also check safety signs and safety equipment to ensure they are complete and effective, capable of guiding operators in proper use.
