Description
Technical field
The present invention relates to a kind ofly, belong to technical field of new energy application the grain header of hydrogen fuel cell new forms of energy as power set.
Background technology
In the national chief of the Department of Agriculture forum agricultural machanization industry group discussion meeting that on July 20th, 2010 held in the Kunshan City, Jiangsu Province, the vice-minister Zhang Taolin of the Ministry of Agriculture points out when speaking of the important function of grain combine: ' three summer jobs ' transregional machine in 2010 is received in creates multinomial new peak again under the difficult situation, 41.4 ten thousand of the whole nation day input grain combines, day mechanical harvest area is up to 2,776 ten thousand mu, continuous 5 nature's mysteries are received area more than 2,000 ten thousand mu, machine receipts level reaches 86%, and the wheat harvest time ratio shortened 4 days last year.
Inventor's Miao TongChun of this patent in 71 years old this year is when writing the present patent application file, remember own past event in the time of 25 years old to 35 years old: in the rush season of summer harvest wheat, Miao TongChun stand in day and night from the former Soviet Union buy with on the Working pedal of Stalin's name as the grain combine of model, participate in the work of bundle loading gunnysack mouth, spot-check the threshing quality simultaneously.This class combine all provides power by old-fashioned diesel engine, thick blast pipe sprays a burst of black smoke on the diesel engine, people at that time do not recognize that the discharging great amount of carbon dioxide can cause environmental pollution and greenhouse effect, can bring flood, arid, high temperature, the multiple natural calamity of low temperature to the mankind.Liaoning met with and took turns precipitation this year the 5th on August 22nd, 2010, influenced by floods, and the whole city, Dandong shifts population 9.4 ten thousand people in advance, dead 1 people of 4 people is missing, and the whole city bursts the dikes 83.47 kilometers, and road interrupts 297 times, more than 20 ten thousand people's flood strucks, 195 tame industrial and mining enterprises stop production.
Nowadays, China can manufacture advanced longitudinal axis stream grain combine and twin-roll grain combine, combine develops to the direction of high-power, high efficiency, high added value, high technology content, existing problems are that all grain combines still rely on single fossil energy at present, just rely on diesel engine that power is provided substantially.Although new-type diesel engine has many progress compared with old-fashioned diesel engine, yet the carbon emission amount is still not little.41.4 ten thousand grain combines that power all is provided by diesel engine of China, receive wheat season from south to the central plain area again to the northeast llanura, continuous transregional machine was received nearly two months, to discharge what ton carbonic acid gas altogether? at present, the fuel consumption of Chinese agriculture machinery diesel engine unit power is than developed country mean height about 30%, a large amount of fuel oils has been wasted in the highly energy-consuming of Chinese agriculture machinery, maximum discharge, has raised agriculture production cost, has more caused an environment difficult problem.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, provide a kind of the grain header of hydrogen fuel cell new forms of energy as power set.Thoroughly change the present situation of the single dependence fossil energy of power of the required usefulness of grain header, reduce the consumption of Imported oil, promotion progressively replaces the fossil energy that causes environmental pollution with reproducible clean energy resource.Inventor's Miao TongChun of this patent is the Chinese agriculture mechanics meeting energy source and power director of association, and Miao TongChun is proposed: the hydrogen fuel cell new forms of energy that should accelerate to adopt the protection environment in agricultural machinery technological field.
In recent years, the solar electrical energy generation of China and the scale of wind-power electricity generation are increasing, all there is the lability that causes because of sunlight power or wind-force size variation in this two big class primary energy, photovoltaic electric power and wind-powered electricity generation also run into many difficult problems in being incorporated into the power networks, photovoltaic electric power and wind-powered electricity generation are changed into secondary energy sources-Hydrogen Energy, can provide stable to grain header, be convenient to the clean energy resource that stores and transport.
Hydrogen Energy is efficient zero energy that pollutes, the wide material sources of hydrogen.The mankind have worked out solar energy electrolyzing water hydrogen manufacturing, the hydrogen manufacturing of solar energy pyrolysis water, the hydrogen manufacturing of solar heat chemistry, solar photolysis water hydrogen, photosynthesis hydrogen manufacturing, biological hydrogen production, wind-force hydrogen manufacturing, methane cracking hydrogen production, biomass hydrogen preparation several different methods, wherein the raw material of most of method or condition are that the rural area possesses, grain header has only the employing Hydrogen Energy, could be to the rural ecological environmental nonpollution.
