Abstract
The graduation project topic is mine belt transportation system overall program design. Strictly follow the design principles of belt conveyor design calculations. First, get current development of domestic and foreign mining conveyor belt through the network, books and other information channels, and a comparative analysis of the two, pointing out the gap between China and foreign belt conveyor. Next to the ore with the structure and principles of the belt conveyor brief overview; then mine were analyzed using content selection principles and calculation of belt conveyor components, and then follow these design principles, by calculating the known parameters, thereby performing selection and design of components, the last of the main components of the conveyor to be checked. Mine belt conveyor is mainly composed of six parts: gears, drives, rack and conveyor belt tensioning device. According to the theoretical analysis of this subject on the basis of calculations made on the design of electrical control system. The core components of the electrical control system adopts PLC. But because of the design of the device to work in the mine, the working environment humidity, dust, and have a lot of uncertainty in the design should take into account. The design in strict accordance with standard design principles mine belt conveyor, through a series of calculations, to meet the design requirements of the premise, to determine the overall design of mechanical components and control to ensure the design of safe and reliable to complete the task.
