Description

[Name of invention made by ISA in accordance with Rule 37.2] Electric Harvester

Technical field

The invention relates to the field of agricultural machinery, in particular to an electric harvester and its application.

Background technique

With the continuous development of the agricultural industry and the continuous advancement of science and technology in recent years, the means for farmers to carry out agricultural production has been increasing, and the agricultural machinery industry has also shown a good momentum of development. In order to improve the economic benefits of agriculture and promote economic and social development, each Agricultural machinery has sprung up like mushrooms, and has entered the rural households, bringing benefits to farmers. Modern agriculture has almost completely relied on agricultural machinery and equipment from planting, plant protection to harvesting. This has played a certain role in rapidly increasing labor productivity and promoting economic development. The mechanization of agriculture has improved the efficiency of agricultural production, brought great convenience to farmers, and played an important role in the rapid development of agriculture.

However, with the increasing awareness of human environmental protection, the pollution caused by agricultural machinery to the environment has caused heavy burdens on the environment and has attracted people's attention. Because the agricultural machinery currently used is mostly powered by diesel engines, it not only causes energy waste, but also generates more exhaust gas, which causes serious pollution to the environment. Over time, it seriously endangers human health, and the environment is the space space for human survival and development. The combination of all its material elements is the material basis for human development. Therefore, increasing the pollution control of agricultural machinery has become an urgent problem to be solved.

As a kind of agricultural machinery, the harvester plays an important role in the harvesting of crops, improves the harvesting efficiency of crops, and reduces the labor burden of farmers. It is one of the indispensable agricultural machinery equipment in modern agricultural harvesting. However, at present, more than 95% of the harvesters are equipped with diesel engines. The main components of the exhaust gas formed by combustion of combustible mixture (diesel and air) during diesel engine operation are mainly carbon dioxide, carbon monoxide, hydrocarbons, nitrogen oxides, Soot particles, etc., these exhaust gases are discharged through the exhaust pipe, and then enter the air, causing damage to crops, causing pollution to the environment, and being seriously absorbed by the human body. In the harvest season, when many harvesters work in the field, the carbon dioxide emitted will cause the greenhouse environment to produce a greenhouse effect, and the earth will gradually warm; the carbon monoxide emitted by it is a toxic gas, reducing the blood oxygen supply capacity of humans and animals, harming People's health; the hydrocarbons they emit are highly toxic compounds composed of many compounds, which are harmful to people's health; the nitrogen oxides emitted by the gas will form ozone when heated and exposed to the sun, on the surface. Ozone in the form of smoke, which causes respiratory diseases and inhibits the growth and reproduction of plants, is the main cause of heart and lung disease and environmental smog; its carbon particles contain many carcinogenic substances, which are easily affected by the human body. Inhalation deposits in the lungs, causing long-term damage to the human body, directly jeopardizing the health and life of the human body.

In summary, agricultural production cannot be exchanged for the economic benefits of agricultural production at the expense of the environment. In the process of modern agricultural development, human beings face problems such as environmental pollution, resource consumption, and imbalance of social resources. People need to explore new development paths and achieve sustainable development. To this end, agricultural machinery is in urgent need of exploring new development processes. The technical system guarantees the harmonious development of human society and the environment. Therefore, the producers of harvesters still need to develop high-tech to solve the pollution problem of harvesters, so that agricultural production forms a systematic green project and maximizes the comprehensive economic, social and ecological benefits.
