The cause of maintenance accident of corn spraying machine
1. Preparation before maintenance is not enough. Before the locomotive is repaired, it is necessary to make good preparations. Such as farm machine fuselage or farm tools cushion firm, with a hard cover tire. These preparations may seem small, but they must not be ignored.
2, debugging, repair or troubleshooting without cutting off the power supply. Did not cut off power and maintenance work, it is a kind of serious violation of agricultural machinery operation rules actually. Although agricultural machinery supervises branch to emphasize repeatedly, but many machine hands still go their own way, cause this kind of accident to appear ceaselessly. For example, some machine hands in the harvesting operation, because of the cutter wound weeds, transportation or threshing parts blocked, belt off and other small faults, in order to rush the time, in the case of not cut off the power, directly use the hand to troubleshoot or install, often resulting in injured hands or fingers are cut off.
3, maintenance technology is not skilled. The mechanic is not skilled in maintenance technology, does not understand the structure of mechanical parts, does not understand the tips of disassembly and installation, blind hard disassembly and installation, by force, the consequence is that it will damage parts. Second, once the wrench and other tools due to too hard slip, often cause repairmen injured.
4. The maintenance is not complete. Many machine hands greedy for immediate interests, that repair can save the province, usually do not pay attention to inspection, maintenance. And once there is a fault in the busy time of agriculture, the maintenance is only fast, and the method of treating the head and foot, resulting in frequent maintenance accidents.
5, do not pay attention to fire prevention. Agricultural machinery repair places generally need to use diesel or gasoline to clean parts, so the repair site should be strictly prohibited fireworks. When performing electrical welding, pay attention to whether there is a fuel tank nearby. The repair shop should be equipped with fire protection equipment in case of emergency. For example, when a farm machinery repair shop repairs the engine in the hangar, it cleans the parts with diesel oil, and the result is that the fire burns diesel oil. Fortunately, the rescue does not lead to disaster in time.
