Of agricultural machinery of Energy and Environmental Design

Paper Keywords: Energy and Environmental Design trends in agricultural machinery
Abstract: Agricultural machinery energy saving design is a new design philosophy. This paper analyzes the design of energy-saving agricultural machinery the meaning and significance of the foundation. Expounded energy saving design trends of agricultural machinery.

1 Design of Agricultural Machinery significance of energy saving
At present, China's agricultural machinery is used in traditional design methods, resources and energy consumption, low efficiency, environmental pollution is serious, is a high input of the extensive mode of production. With the continuous development process of agricultural modernization, agricultural machinery also toward the high-quality, multi-function, low power and low cost direction. of a large number of agricultural products each year scrapped, after the design of energy-saving environmental protection products, agricultural machinery parts can pose for easy separation and recovery and regeneration of the minimum consumption to reduce or even eliminate agricultural products life cycle at the end of the pressure, * so that waste and garbage pollution to a minimum. agricultural machinery not only to the community energy saving design provides a high quality, low cost products, but also stimulate business or the entire Nongji revitalization and comprehensive development of the industry, improve the competitiveness of agricultural products to effectively occupy the domestic market and expanding exports. energy saving design has become the inevitable trend of development of agricultural machinery.

2 energy-saving design trends of agricultural machinery
2.1 cleansing of agricultural machinery
Power for the internal combustion engine used to provide agricultural machinery, internal combustion engine environment indicators are the main problems: one-time energy consumption of oil; noise, air pollution; heat emissions and oil pollution. Gas emissions and oil pollution on the environmental impact of large agricultural, NOX emissions , HC compounds directly affect the quality of agricultural products and agricultural sustainable development. agricultural machinery Power environmental type design should give priority to choose their power-driven farm machinery, to accelerate development of solar energy, hydrogen, vegetable oil, natural gas engines. while accelerating the engine design of environmental chemistry Research, including the use of lead in gasoline and gasoline abrasion resistance, low sulfur diesel fuel and diesel, lubrication, tribology and ecological ecological fuel, gasoline and gasoline detergent sediments, particles and smoke and diesel engine Combustion, lubricants and additives catalytic converter emissions, lubricants, biodegradable lubricants and biological degradation, catalytic combustion / combustion, engine mechanical and chemical materials and other measures. reduce oil consumption, noise pollution, air pollution, heat emissions and oil pollution. to take adaptive active noise control system to control the engine noise.

2.2 The design of recyclable products
Recyclable design early in the product design to fully consider the possibility of parts and materials recycling, recovery value of the size of the recycling method and process of recycling the structure and other issues, ultimately part of the use of material resources and energy, the highest level of the lowest level of environmental pollution of a design. For example, commonly used in agricultural machinery fasteners (bolts, nuts, etc.) recycling and reuse.

2.3 product design for disassembly
Designed by the designer to make the structure easy to disassemble and maintain. In the design phase, the modular design method can be used, that the different functions within a certain range of different functions or the same performance specifications of the products of different functional analysis, on this basis by a series of modules designed by the choice and combination of modules constitute different products for various needs. In this way, can solve the products of different specifications, product design and manufacturing cycle and the contradiction between production costs, but also for product The rapid replacement shorten design cycles, reduce costs, is conducive to recovery and reuse, in order to achieve conservation of resources and energy, protect the environment.

Since early in the product design considering product recovery and reuse of such properties, so the cost analysis should take into account the cost of processing contaminants, product disassembly and recycling costs.

2.5 Material Selection
environmental protection should be the source material is rich, easy to use, easy recycling and environmental impact of the material. Material selection is an integral part of environmental design, it is the early product development and design one of the main decision-making. Material selection should be reduce the type of material, less toxic, hazardous materials and precious scarce materials, as well materials management and waste classification and recycling of scrap. With a reasonable choice of materials of environmental protection products on the environment can be achieved to minimize the negative effects. The current in this area Research work are: environmental design to determine the material requirements; environmentally friendly materials selection principle; the impact of material selection factors; development and application of environmentally friendly materials; new features (of environmentally friendly) materials development and application; recycling materials re- the application of resources.

3 Environmental Design in agricultural machinery design outlook
One of the essential features of green design is to not affect the life of the product, function, quality indicators, relying on technical means and management practices to achieve greater resource and energy efficiency for the purpose of an advanced design. From Jingji Xue layers of meaning, environmental technology is a bad allocation of resources-saving technologies relative value, that is equal in the use of resources, under the premise of energy, environmental design is the design than the traditional method of trying to get a greater number of better quality products, so the production process from the extensive type to intensive advanced design techniques. China joined WTO, agricultural machinery products will be increasingly fierce market competition, environmental protection, improving product design is a powerful competitive weapon.

In summary, agricultural machinery after the use of environmentally friendly design with a series of advantages that the environmental design of agricultural machinery has a good prospect. Environmental design to achieve sustainable human development, with high-quality living environment, a necessary requirement to enjoy a healthy life is the general trend of the future technical and economic development.
