With the development of agricultural mechanization, the maintenance of agricultural machinery has increased, and various types of accidents that occur during maintenance have also increased. The main causes of farm machinery maintenance accidents are:
First, the preparatory work before the maintenance is not sufficient. Locomotives must be fully prepared before maintenance. If the tractor body or agricultural implements are firmly supported, cover them with hard objects. These preparations may seem trivial but they must not be ignored.
Second, debugging, repair or troubleshooting does not cut off the power. Failure to cut off power and perform maintenance work is actually a serious violation of farm machinery operating procedures. Although the agricultural supervision department repeatedly emphasized, many of the operators still go their own way, leading to the emergence of such accidents. For example, when a certain operator encounters a small fault such as clogging of weeds with a cutting knife, feeding or threshing, or a belt falling during a harvesting operation, in order to grab the time, if it does not cut off the power, it is directly eliminated by hand. Faults or installations often result in severed hands or fingers.
Third, maintenance technology is not skilled. Mechanic due to unskilled maintenance technology, did not understand the structure of mechanical parts, do not understand the disassembly and assembly tips, blind hard dismantling and hard-installed, with reckless effort, the consequences of one will damage parts. Second, once tools such as spanners are slipped too hard, repairers are often injured.
Fourth, maintenance is not complete. Many drivers are eager to cope with the immediate interests and think that when repairs are made, they can be saved, but they usually do not pay attention to inspection and maintenance. However, if there is a breakdown when the farmers are busy, they only need to be quick when repairing, and they will take measures to deal with the headaches and foot pains, resulting in frequent maintenance accidents.
Fifth, do not pay attention to fire prevention. Farm machinery repair sites generally need to use diesel or gasoline to clean parts, so firework is strictly prohibited at the repair site. 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 any accidents. If an agricultural machinery repair shop repairs an engine in a hangar, because of the cold weather, the diesel fuel is burned with an open flame and the result is that the flame burns diesel fuel. Fortunately, the fire did not cause disaster.

Refers to the trading of minerals in international trade. Minerals in international trade refer to the four major categories of iron ore, non-ferrous metal ores, rare-metal ores and non-metallic Mineral Products.
Mineral classification:
- According to the genesis and formation conditions of mineral resources, it is divided into endogenous minerals, exogenous minerals and metamorphic minerals.
- According to the mineral composition and structural characteristics, is divided into inorganic minerals and organic minerals;
- According to the output status of minerals, it is divided into solid minerals, liquid minerals and gas minerals.
- According to the characteristics of the mineral and its main purpose, it is divided into energy minerals, metal minerals, non-metallic minerals and water and gas minerals.
