1. Load operation without trial run
After the new or overhauled engine is loaded with the load without commissioning, it will cause serious wear and tear on the moving parts, which will cause the parts to lose their working ability and shorten the service life of the whole machine. In order to reduce the wear of the parts in the initial stage, check and eliminate the problems existing in the manufacture, repair and assembly of the parts, so that the various parts of the machine are coordinated with each other. The new purchase or the overhauled engine should be in accordance with the relevant specifications (load from small To large, speed from low to high, gear from low to high) run-in test run, check and adjust and then add the load into operation. Doing so can give full play to the mechanical efficiency, prolong service life and prevent accidents.
2. Smoking and one-handed control when driving a tractor
Some drivers are accustomed to smoking while driving, on the grounds that smoking can solve boredom. As everyone knows, smoking not only distracts the driver's attention, but also affects his sight. Smoke from smoking causes severe irritation to the eyes and throat, causing the operator to shed tears or open eyes. The cough is exacerbated. In particular, when driving a tractor without a cab, driving in the wind, smoking, soot, and splashing Mars can all be accidents. In addition, when operating in a wheat field, smoking can easily lead to fire and cause loss of life and property.
Perhaps because of smoking, slapstick, perhaps the driver thinks that the operation level is high, people can often see some drivers driving with one hand or using the foot to control the locomotive direction. You know, although the tractor's speed is not fast, it still belongs to the motor vehicle; the driver's ability is even higher and it is not performing acrobatics. In the event of an emergency, the operator is in a hurry, an accident, and regret late.
3, overloaded speeding people and goods mixed
Overloading or speeding up or running is a concrete manifestation of the operators earning money eagerly. The overload of the tractor is very harmful, that is to reduce the braking performance of the whole machine, which in turn aggravates the wear of the parts. Once the bumping of the goods is not tight or the road is uneven, it is very prone to rollover accidents. The speed is too fast and the safety braking distance is correspondingly longer. Therefore, the braking device is required to be more sensitive and the driver response is more agile in order to be able to quickly stop at a critical moment.
People and goods are mixed and even tractors have become tools for people to carry passengers in places where traffic conditions are backward. This kind of operation is a serious threat to the safety of people’s lives and property and is an illegal act.
4, excessive fatigue driving
Some drivers have to work hard day and night in long-distance transportation. They fight hard, eat badly, and have insufficient sleep. It is hard work. As everyone knows, this practice is very unsafe. Sleep is the normal physiological needs of people. When a driver who is not fully rested drives his car, he often causes traffic accidents due to ambiguity and sleepiness. This is already harmful.
5, locomotive downhill slide
When an object slides along a slope, the gravity of the object will decompose into a component along the direction of the downhill slope, and the object will be accelerated with an acceleration so that it will slide faster and faster. If no counterforce is applied in the middle, the object will eventually rely on frictional resistance. Slow down and stop. If a sudden resistance is applied to the object in the middle, the object tends to roll over. The reason why the tractor is not allowed to coast when it is downhill is the same.
6, the engine does not turn off when troubleshooting
Some of the operators found that the tractor or the supporting machine had a malfunction during the operation. For the convenience of the diagram, it was adventurous to eliminate the malfunction when the engine was not turned off. As a result, the accident caused personal injury or death and was not worth the candle.
7. The tractor does not cut off the power of the work machine when carrying out the field transfer
When the tractor is transferred in the field, it does not cut off the power, causing the trencher and the rotary cultivator blade, the harvester cutter, the seeder opener, etc. to be damaged or bump into others when passing through field hard, small ditch or other obstacles.
8. When the operator thrashes away from the job
During the busy season, some of the crew worked tirelessly after working overtime, so when the threshing operation started, he went to bed and went to sleep. This type of accident due to the operator's absence from work, resulting in thieves injury accidents showed an upward trend.
9, short-term parking foot clutch does not pick file
When a driver encounters friends and relatives while driving, he will have to stop and talk a few words. However, there is a potential cause for accidents by clutching the clutch and not removing the gear. At the same time, this practice also tends to increase the clutch wear and shorten the service life of the clutch.
10, before hitting the throttle
Before the locomotive started, the tractor driver always liked to bang a few throttles to make the engine speed suddenly increase. This has the following disadvantages: 1 An abrupt change in engine speed causes the valve spring and injection pump plunger return spring to break due to resonance. 2 The engine speed drastically changes, resulting in poor lubrication of the surfaces of the friction parts and increased wear. 3 The relevant moving parts of the engine are subject to excessive impact loads and fatigue damage. 4 The engine piston speed is greater than the valve return speed, which causes the valve lock clip to fall off and the valve to drop into the cylinder causing an accident.
