Abstract

In the graduation design, I through the network, the guidance of books in the library and their teachers of this graduation project were full range and reasonable comprehensive consolidation analysis, learning and improvement, and the use of CAD, CAXA drawing software draw orchard weeding machine assembly drawing and parts drawing. At the same time, the accuracy of the structure of the parts and the strength of the structure of the parts are calculated.. In the rapid development today, the environmental pollution is becoming more and more serious, their environment purification capacity has been unable to meet the destroyed degree, human excessive pursuit of development and ignore the protection of the environment. This banded behavior, to meet their swelling of the material at the same time, for the future of human survival environment buried under the huge hidden trouble. These hidden dangers in the passage of time has been gradually exposed, for example: melting glaciers, greenhouse effect, land desertification; with the national "energy-saving emission reduction, low carbon life" policy vigorously to promote the implementation and execution, R & D a no waste water, noise, air pollution, convenient operation, beautiful appearance of the green orchard weeding machine is imminent. I design the orchard weeding machine the main principle is to use the scroll wheel to drive the mechanical movement. Its advantages not only simple structure,

connection is smooth, noise is small, easy to operate. It can bring convenience to the user, but also can create a comfortable, quiet working environment for the people around, so as to meet the needs of the general public.. The design of the orchard weeding machine without an engine driven, no pollution, no complicated operating system, can use close to common people's life, is the ideal lawn mower. Say the reason is because the original power device for engine powered lawn mower, maintenance, repair costs are very expensive, and security is not high, comfortable operation low, sell price is also the general public to accept, so I design the orchard weeding machine for ordinary people in the future is there are broad prospects for development. The design of the orchard weeding machine on both sides of the symmetrical, is characterized by simple structure, especially homogeneous force, running very smooth, friction resistance and small bending of good, not easy to be blocked, particularly strong adaptability. At the same time, through the design, and deepen the knowledge I learned in the University for four years, comprehensive application of knowledge in practice, makes full use of the research object and the research on their own is a great improvement, master knowledge of mechanical design and mechanical design meter manufacturing and automation reached a new height.
