With the continuous development of agricultural industry and the continuous progress of science and technology in recent years, the means of farmers for developing agricultural production is continuously increased, the agricultural machinery industry also presents good development momentum, and in order to improve the agricultural economic benefit and promote the development of economic society, various agricultural machines emerge like bamboo shoots in spring after rain, enter thousands of households in rural areas, and bring the benefit of being tailored to the farmers. All links from seeding, plant protection to harvesting and the like of modern agriculture are almost completely finished by agricultural machinery, so that certain effects are achieved for rapidly improving labor productivity and promoting economic development. The agricultural mechanization improves the efficiency of agricultural production, brings great convenience to farmers and plays an important role in the rapid development process of agriculture.
However, with the increasing awareness of human environmental protection, the pollution brought by agricultural machinery to the environment at present causes the environment to bear a heavy burden, and people pay attention to the pollution. Because the prior agricultural machinery mostly uses a diesel engine as power, not only energy waste is caused, but also more waste gas is generated, the environment is seriously polluted, the human health is seriously harmed after a long time, the environment is a comprehensive body of space and all substance elements thereof which are depended on survival and development of human beings, and the environment is a substance basis for the development of human beings, and therefore, the pollution treatment of the agricultural machinery is increased, and the problem to be solved is urgently needed.
The harvester is one of agricultural machines, plays an important role in the harvesting operation of crops, improves the harvesting efficiency of the crops, reduces the labor burden of farmers, and is one of indispensable agricultural equipment in modern agricultural harvesting. At present, however, more than 95% of the harvester is equipped with a diesel engine, when the diesel engine works, the main components of the waste gas formed by the combustion and work of combustible mixed gas (diesel oil and air) are mainly carbon dioxide, carbon monoxide, hydrocarbons, nitrogen oxides, soot particles and the like, and the waste gas is discharged through an exhaust pipe and then enters the air, so that the waste gas damages crops, pollutes the environment, and seriously harms the human health after being absorbed by the human body. In the harvesting season, when a plurality of harvesters work in the field, the discharged carbon dioxide can cause the greenhouse effect to the atmospheric environment, and the earth is gradually warmed; the carbon monoxide discharged by the device is toxic gas, reduces the blood oxygen transfer capability of people and animals, and is harmful to the health of people; the discharged hydrocarbon is a compound with strong toxicity formed by mixing a plurality of compounds, thus causing harm to the health of people; nitrogen oxides discharged by gas can form ozone when being heated and directly irradiated by sunlight, the ozone on the ground surface appears in the form of smoke, respiratory system diseases can be caused, the growth and the reproduction of plants are inhibited, and the nitrogen oxides are the main causes of cardiopulmonary diseases and environmental smoke of people; the carbon particles discharged by the device contain many carcinogenic substances, and are easy to be inhaled by human bodies and deposited in the lungs, so that the device can cause long-term damage to the human bodies and directly harm the health and the life of the human bodies.
In conclusion, agricultural production cannot trade environmental for the improvement of economic benefits of agricultural production. In the development process of modern agriculture, people face the problems of environmental pollution, resource consumption, imbalance of social resources and the like, people are required to explore a new development road to realize sustainable development, and therefore, agricultural machinery is urgently required to explore a new technical system in the development process to ensure the harmonious development of the human society and the environment. Therefore, manufacturers of harvesters still need to develop high and new technologies to solve the pollution problem of harvesters, so that agricultural production forms a green project of a system, and economic, social and ecological comprehensive benefits are maximized.
