Abstract: The main task of this project is to design the auxiliary teaching tools for the classroom teaching of Geography in the teaching of mechanical design and mechanical principles in Colleges and universities.The three ball instrument teaching appliance can be used for classroom teaching. It can demonstrate three space of the sun, the earth and the moon on the mutual movement relationship between, earth's rotation and revolution caused by the length of day and night changes, lunar eclipse, eclipse, etc. natural phenomena can be abstract and difficult to understand geographical knowledge transformation into visual image of the dynamic picture, and can let students personally operation, help students better understand the astronomical phenomena. Three ball teaching instrument equipment can realize the manual operation can achieve electric operation, with calculation, modeling, manufacturing, assembly and debugging of the process, three ball teaching instrument equipment to meet the basic operation and demonstration in classroom teaching.
