Description

Technical Field

[0001] The utility model relates to a pure electric self-propelled grain harvester. Background Art

[0002] At present, the rapid development of agricultural machinery has saved a lot of labor for my country's agriculture, but it has also brought about a lot of energy consumption. The resources on the earth are limited. Agricultural machinery not only brings convenience to people, but also pollutes the environment. The exhaust emissions of the engine cause the greenhouse effect of the earth, and also cause the destruction of the ozone layer, forming atmospheric environmental problems such as acid rain, which in turn has caused great harm to animals and plants. In the face of air pollution brought to rural areas by various agricultural machinery, people can directly smell the engine gas emissions, with a pungent odor, incomplete combustion of the atomized mixed gas. With the improvement of living standards, human beings have higher and higher requirements for the living environment, and the call for reducing fuel engine gas emissions is also increasing day by day. With the adjustment of agricultural planting structure and the improvement of large-scale production of agricultural machinery, as well as the implementation of the national agricultural machinery purchase subsidy policy, modern agricultural machinery is increasingly needed by farmers, and agricultural mechanization is entering a period of rapid development. Compared with traditional harvesters, the appearance of pure electric self-propelled grain reaper not only greatly reduces the labor intensity of farmers, greatly improves the work efficiency of farmers, but also brings us the benefits of clean energy, zero environmental pollution, and low noise. Summary of the invention

[0003] The purpose of the utility model is to overcome the problems of the prior art, such as large energy consumption, serious environmental pollution, and high noise of self-propelled grain cutters. The present invention provides a pure electric self-propelled grain cutter, which is driven by a battery pack and an electric motor. It does not produce exhaust gas when working, and does not emit tail gas pollution. It is very beneficial to environmental protection and air cleanliness. It can be said to be almost "zero pollution". The pure electric self-propelled grain cutter does not make noise like a traditional cutter, and the noise it produces is almost negligible. The use cost of the pure electric cutter is low, which is only about one-fifth of that of a diesel cutter. In addition, the energy conversion efficiency is high, and the energy during braking and downhill can be recovered at the same time, so as to improve the utilization efficiency of energy. At night, the cheap "valley electricity" of the power grid is used for charging, which plays a role in smoothing the peak-valley difference of the power grid. The pure electric self-propelled cutter is driven by an electric motor and a battery, and does not require the cumbersome maintenance items of traditional engines, such as: changing engine oil, filter element, belt, etc. Electric reapers only need to check the motor battery and other components regularly. Pure electric grain reapers use solar charging technology to charge the battery pack at any time during the day, especially on sunny days, when the charging effect is better.
