The combine harvester has a complex structure and is expensive. When the harvesting operation is carried out, the weather is hot or the weather is dry. If there is a slight negligence, a fire is likely to occur, causing great economic losses to the owner and the farmer. Attention must be paid. First, the cause of the fire combine harvester 1, electrical equipment short circuit failure. According to statistics, due to the circuit caused by fire accidents accounted for about 2/3 of the total number, the main reason is to ignore the inspection of electrical lines, indiscriminate access to the wire, to eliminate electrical faults regardless of their firmness and safety, resulting in loose thread Eliminated by scratch to produce electric spark, or aging damage of the wire, due to short circuit in ground. 2, exhaust pipe fire or overheating. Long-term overload operation or engine oil supply time is too late, causing the exhaust pipe to overheat or even become red hot, igniting nearby flammable materials; or when the fuel is incompletely burned, carbon in the cylinder or exhaust port. Excessive spouting of Mars, hot Mars temperatures of up to 1000°C, splashes on crop stalks causing fire. 3, gasoline starter carburetor tempering. The high-temperature air-fuel mixture that burns during tempering is spouted from the carburetor in reverse, and burns when combustibles such as crop stalks are burned. 4, turbocharger failure. When the exhaust gas turbocharger is poorly lubricated or has a mechanical failure, the exhaust heat causes the supercharger to catch fire, which then ignites the engine. 5. When the combine harvester is repaired, the welding slag falls into the nearby grass, straw and other combustibles causing the fire. 6, careless operation or maintenance, the metal parts such as wrenches fall on the battery electrode, grounding produces a strong spark, igniting diesel fuel, oil or flammable materials around. 7. The operator smokes during the harvesting operation. Falling soot falls into the dry grass dust, or throws cigarette butts, causing a fire. 8. When the threshing operation is performed in autumn and winter, the artificial fire causes improper treatment of the residual fire, and the straw is blown by the wind to reach the harvester; or by using an open fired roasting car, a roasting oil road, and a roasted water tank to help start the fuel. , tubing. 9. Failed to rule out the malfunctioning combine harvester, sick operation, and did not clear the part of the wrapped grass in time, so that the parts dry friction and heating or bearing overheating, or electrical work produces sparks, igniting dust or grass clippings. 10. Farmers burn wheat mash or burn crop stalks, “burning togetherâ€, and harvesting machines. Second, the prevention of fire accidents of combine harvesters should first of all be thought highly of, and secondly, the following technical points should be mastered: 1. The harvester must be carefully repaired and maintained before it is put into harvesting operations, and “Five Nets†should be implemented according to relevant regulations ( Oil, water, gas, machinery, tools, "four leaks" (oil, water, gas, electricity), "six closed" (diesel tank ports, gasoline tank ports, oil filling ports, carburetor, magneto , oil inspection port), "a good" (technical state), while maintaining the engine and fuel tank clean, do not use gasoline to wipe grease. 2, always check the electrical equipment, see whether the connection of the circuit wire is loose, and whether the equipment is damaged. Wire connectors shall be firmly connected with bolts with spring washers; circuit harnesses and wires shall be covered with plastic pipes and sealed to prevent water from entering the water; no oil shall be allowed near the wires, and the batteries shall have good protective equipment to prevent metal objects from falling. Short circuit arc. 3, the electrical circuit away from heat, with a clip fixed firmly through the moving parts of the wire, the middle span of the wire shall not be too long or too short, to prevent the rotation or vibration caused by wire wear, scratches bare, ground iron fire. 4. Always check the start-up time of the gasoline engine to prevent the carburetor from tempering when working in the field. It is advisable to install a quality Mars collector on the engine host. 5. Always check the working conditions of the injector and the high-pressure pump, as well as the air filter, exhaust pipe, and fuel quality, and repair or replace if necessary. 6, the operation can not be overloaded for a long time to operate, control the engine speed, not suddenly big or small, but also can not shout throttle; when the tank is open, the engine overheating should pay attention to shutdown and cooling. 7. When harvesting, add fuel and water regularly, check the high-temperature parts of the engine, and remove nearby combustibles and oil. 8. When working, it must be equipped with necessary fire-fighting equipment, such as fire extinguishers, sandbags or sandboxes, shovels, and sacks. 9. When the harvesting operation is performed, the drum wraps the grass and the fire will be rubbed. Therefore, the clearance of the drum must be adjusted to be consistent. During operation, the inspection should be performed to remove the grass in time. In addition, the rotating parts should always be oiled and lubricated to prevent the frictional heat from igniting grass clippings. 10. There should be good lighting equipment during night operation. It is strictly forbidden to open flame during maintenance and trouble shooting, check or add fuel, so as to avoid explosion or detonation of high-temperature diesel steam in the fuel tank in case of open flame. 11. During operation, operators are strictly prohibited from smoking. 12. After the engine maintenance or overhaul, it is necessary to completely remove the oil smeared on the locomotive; when it is necessary to short-circuit the electromagnetic switch to start the engine, it is necessary to remove the accumulated dust, dust, and oil stains at the electric starter to prevent overlap. EDM ignites these combustibles. 13. When working in the field, especially at night, it is necessary to prevent the protrusions of the combine harvester, exhaust pipe, granary, unloading food and auger from touching and breaking the farm power lines in the field and causing electric shock or fire. 14. At the end of the operation, all food and weeds left in the machine room should be removed to prevent rats from biting and biting off wires and causing short circuits. Do not overlook the inspection of electrical circuits before each start. 15. When the operation is stopped, the total power supply must be cut off, and no main power switch must be installed. After the work is completed, the dust and wraps of the crops are promptly removed, and the engine is clean and free of oil. 16. When welding work is required in the repair, the combustibles around the welding site shall be cleaned first, the battery ground wire shall be removed, and the main power switch shall be disconnected; when the welding is performed, the grounding wire of the electric welding machine shall be as close as possible to the welding. Parts to prevent sparks caused by poor contact between parts. 17. It is prohibited to burn crop stalks. 3. When the combine harvester is on fire, the combine harvester accidentally catches fire. Because the air in the field is well circulated and often over-fired, do not expect firefighters to extinguish the fire. The correct approach is to base itself on self-help and extinguish the fire at the initial stage. If the engine is hot, oil leaks, electric leakage or grass dust accumulates during the harvesting operation, the harvesting shall be stopped immediately, and the field plots shall be withdrawn from the field as soon as possible to the harvested plots, and then the machine shall be shut down and extinguished, and the vehicle shall be equipped with fire extinguishers, dry sand, The sacks or shovels should be used to extinguish the fire. Try not to extinguish the fire in the field so as to prevent a large-scale field fire. When the fire is extinguished, the oil circuit should be cut off to prevent the fuel from leaking and causing the fire to spread. If the threshing part of the harvester catches fire due to the grass wrapped around the harvester, it should also be withdrawn from the work field as soon as possible. The cut-off site should continue to work and enter the inside of the harvester. The fired straw spits out to prevent the internal parts such as the conveyor belt from being burned out; at the same time, fire extinguishers, sandbags, etc. are used to extinguish the flames on the locomotive and on the ground. If a field fire is caused by burning straw, the harvester should be allowed to exit the field as soon as possible and quickly go to a field with no combustibles to avoid “burning togetherâ€.
