设计简介
摘 要
带式输送机式是由承载的输送带兼作牵引机构的连续运输设备，可输送矿石、煤炭等散装物料和包装好的成件物品。由于它具有运输能力大、运输阻力小、耗电量低、运行平稳、在运输途中对物料的损伤小等优点，被广泛应用于国民经济的各个部门。在矿井巷道内采用带式输送机运送煤炭、矿石等物料，对建设现代化矿井有重要作用。带式输送机是连续运行的运输设备，在冶金、采矿、动力、建材等重工业部门、在农业生产中运输粮食以及交通运输部门中主要用来运送大量散状货物，如矿石、煤、砂等粉、块状物和包装好的成件物品。带式输送机是煤矿最理想的高效的连续运输设备，与其他运输设备相比，不仅具有长距离、大运量、连续输送等优点，而且运行可靠，易于实现自动化、集中化控制，特别是对高产高效矿井，带式输送机已成为煤炭高效开采机电一体化技术与装备的关设备。特别是近10年，长距离、大运量、高速度的带式输送机的出现，使其在矿山建设的井下巷道、矿井地表运输系统及露天采矿场、选矿厂中的应用又得到一
步推广。

Abstract
With the development of society and the improvement of people's living standard, people's demand for walnut increased, especially for high quality walnut demand. Walnut is used not only for food, but some developed countries use it to create a variety of new materials, which has been rapid development of walnut industry. Relative to the developed countries abroad, the production process of our domestic walnut is still very backward, still using intermittent Martin method is backward, unable to meet the domestic demand, our country every year to import large quantities of walnut is from abroad, so I did about graduation design walnut vibration conveying equipment. An important component of vibrating conveyor is walnut processing process mentioned in this design.
Vibrating conveyer is the eccentric wheel drives a connecting rod to generate centrifugal force, the materials can be separated. This paper is divided into several parts to illustrate the design process, including the choice of motor, a crank connecting rod transmission design, shaft design, bearing design, selection of the key and the design of the frame, trying to through the design, so that the transport mechanism of walnut is simple, and can improve the efficiency, and also can reduce the energy consumption.
