The paper first introduced the developing situation of belt conveyor at home and abroad and the trend of its development and design purpose and significance, mon telescopic and transmission form in telescopic conveyor. The design process was based on the method of QD80 small belt conveyor, some part of parts were selected from QD80 standard parts, the telescopic agency used screw nut transmission form to achieve the conveyor to expand and contract, relevant parameters were confirmed by calculation. Design a transmission agency with electric motor and gears to drive screw nut agency. The paper also calculated parameters of mobile and change angle functions, some parts would be purchase or have custom - made, and had expectation on future innovation and improvement.
