Precautions for safe use of agricultural machinery

1. Agricultural machinery uses heavy ropes to hang heavy objects. When repairing tractors, it is common for people to use unloading engines, gearboxes, and agricultural machinery with hemp ropes, nylon ropes, and V-belts. This is very unsafe. The correct way is to use a strong wire rope. Tripods, etc. must also be securely anchored. When hanging with a crane, no one can pass or stand under the weight.

2. The wrong way for agricultural machinery to support vehicles. When the tire is damaged or replaced, it is not safe to use bricks, stones, wooden blocks or a single jack to support it. The correct way to do this is to use a jack and a strong wooden pier to pad the frame at the same time. Moreover, the front and rear wheels are also stuck with triangular wood or larger stones to prevent the vehicle from moving back and forth, and the support falls and hurts people. This type of repair is best done on a solid flat surface to prevent dumping and injury.

3. Agricultural machinery tires are inflated for unsafe operation. After the tires are disassembled and reassembled, they are re-inflated without protection. The agricultural machinery causes the steel ring to pop out and injure people. The correct method is to lock the tire, the lock ring, the retaining ring and the rim together with a chain before inflating; the side of the retaining ring can be re-inflated toward the ground or the wall to prevent the wheel from popping and injuring people.

4. The welding oil container does not wash the residual oil. In the case of welding and replenishing the oil container, the residual oil in the solvent must be cleaned beforehand, and the agricultural machinery may cause an explosion when it is welded. The cleaning method is to add vinegar with alkaline water or hot water, and wash it 2-3 times repeatedly, and then control the net, dry and then apply welding. Do not blow dry with high-pressure air to prevent the generation of static sparks and detonate. When welding, first open all the lids. When cleaning large tanks, people who enter the tanks should wear long-sleeved clothes. They should not wear bare feet and should be equipped with protective belts and signal ropes. The working time in the tank should not be too long. There must be someone to look after the can. After the cans are out of the can, wash your face, wash your hands, and rinse your mouth. Wash your clothes with alkaline water and then wash with water.

5. Repair the wrong operation of the brake. When repairing the brakes, the hand and foot brakes are repaired at the same time, the agricultural machinery body is unstable, and the self-sliding roll hurts people. The correct operation is to repair the hand and foot brakes separately to ensure mutual safety. The parking place should be solid and flat, and the front and rear wheels should be locked in both directions with triangle wood to prevent slippage.

6. The wrong operation of the agricultural machinery debugging engine. When debugging the machine, the personnel are close to the dangerous parts such as the fan, the agricultural machinery belt or the exhaust pipe; or the tools and parts are placed on the machine to fall and hurt the machine. The commissioning staff should be neatly dressed. The lady should set the hair up. The non-commissioning personnel should keep away from the machine. When debugging, try to stop the machine. In the lower part of the machine, the fire must be turned off. The fire-fighting should be dispatched to guard the operating mechanism to prevent outsiders from moving. Before you can count the tools and parts, and send a signal.

7. The wrong operation of the agricultural machinery maintenance transmission mechanism. Extend the hand or other object to the transmission station position; the agricultural machinery belt joint is not installed firmly; the belt is picked up during the operation of the machine; the belt is pulled by hand; the machine does not turn off when the belt tightness is adjusted;

8. The wrong operation of the agricultural machinery maintenance suspension machine. When the hanging machine is repaired, it is carried out after the hanging machine has not landed and stopped; when the hanging machine is attached, the large and medium throttle is used, the hooking speed is too fast, the hook gesture is not paid attention to, or the parking is not ready; Maintain or remove the soil; when the lower part of the hanging machine is repaired, it will not be supported and extinguished without stopping the machine. These practices are very dangerous and should be eliminated.

9. The wrong way to start the starter rope for agricultural machinery. When starting with the start rope, the start rope is pulled around the hand, or the rope is wound around the flywheel for more than 1.5 turns; when the flywheel is turned by hand, the oil is continuously turned on and off, and the rotation is too fast, so that the sudden burst, rebound and injury to the finger . valve

10. The wrong operation of the agricultural machinery to start by hand. When the maintenance personnel start the engine with the hand, use the thumb to hold the handle separately from the rest of the 4 fingers, instead of holding the handle after the 5 fingers are closed; press the handle instead of lifting the handle; shake the handle with both hands; or Shake for 1 week instead of 1/2 circle. Any such operation is improper and it is easy to hurt the arm or finger. Especially in the case of excessive ignition or overheating, the backlash phenomenon is more likely to occur.

11. Wrong operation when refueling. Smoking or ignition when refueling the tank or checking the amount of oil; lighting with an open flame when refueling at night; such as portable lights, candles, lighters, torches, etc., without the use of safety lights, battery lights, or electric lights; in the exhaust pipe when refueling One side; the oil drops are not wiped out of the box, dripping on the clothes, not close to the open flame or smoking when not dry; the fuel is poured with water instead of sand, dry soil, canvas, sacks, etc.; The gasoline uses a mouth suction pipe or contacts the oiled parts with the mouth, causing poisoning.

12. The wrong way of adding water to agricultural machinery. Open the tank cover immediately when the engine is hot, especially when it is boiling. Instead of first opening the drain switch, wait for the water pressure to drop, then wrap the lid of the tank with a towel, etc., and turn the body and face to one side and then slowly unscrew.

13. Repair the wrong operation of electrical equipment. When repairing electrical equipment in the vehicle, repair it without removing the battery cable beforehand, causing sparks to cause injury to the fire. If the metal container is used for the electrolyte, it is not ceramic or glass. The more wrong way is to dilute. When concentrated sulfuric acid is poured into concentrated sulfuric acid, the acid splashes and burns. The correct way is to pour sulfuric acid into the water slowly. This must be strictly observed.

14. Eliminate the wrong practice when trapped. After a locomotive or a rice transplanter has a trapped car, the person stays in front of the car or works. Once the locomotive or the rice transplanter releases the trapped car, it will suddenly cause injury and cause an accident.

15. Wrong operation when disassembling the spring. The disassembly clutch spring, the valve lock clip, and the like are not used for special tools, but are picked up by a screwdriver or the like, causing the spring to be ejected to injure the person.
