ABSTRACT
This text mainly introduces the structure, characteristics, applies and the form of the inclined leather belt conveyer, and also introduces its main assembly units in detail, namely belt conveyer, supporting devices, driving devices and the driving principle, the stretch devices, the loading and unloading devices and the cleaning devices. Among them supporting devices used mon are trays, driving devices are the dynamoelectric rollers, the driving principle is that the roller drives the belt conveyer by the friction function. It mainly introduced three kinds of stretch devices. They are spiral type stretch device, the car type stretch device, and the perpendicular type stretch device, and this design adopts the spiral type stretch device. Because the transported materials are the sand and crushed stones, in the design its loading devices adopts the guiding slot, the unloading devices adopts the protecting cover, cleaning devices adopts the cleaning machine. In the meantime, this text also introduces the calculations of each main assembly unit in detail including the belt width, the belt speed, the circulate resistance and the tension, the cleaning machine resistance, the guiding slot resistance, the acceleration resistance at the material entry, the belt conveyer tension, the driving power and the prevent tortion. At the end, it also introduces the conveyance safety and the equipments safety of the machine in brief, which provides us a necessary guarantee in using the inclined leather belt conveyer much better and more safely
