摘 要
我国带式输送机应用范围较广,可用于多种干湿粉状,粒状,块状物料的运输传送,运送量达,运送距离较长,运行阻力小,能量消耗地,受地形条件限制小,在途中可装卸货物,操作简单,运行平稳,易维修;但胶带易受磨损,且坡度不能太大,摩擦力大,且运送粉粒状物料易污染环境,所以这个设计能减少环境的污染,并减少摩擦避免胶带的过度磨损。同时我国的输送机发展水平有了明显的提高,大功率,长距离的带式运输机的新产品开发和新技术的研究都取得了不错的成就。所以带式输送机是最理想的高效连续输送设备,相比较其他设备来说具有明显的优势。故不仅可以在短距离运输内使用,也可以在长距离输送中使用。所以在生产环节的连续性和自动化中起到了极其重要的作用,提高了劳动生产率。

ABSTRACT
Belt conveyor in our country has a wide application range, can be used for a variety of wet and dry powder, granule, block material transportation, transport volume, transport distance is long, little resistance during operation, energy consumption, small restricted by terrain conditions, on the way to loading and unloading of goods, simple operation, stable operation, easy maintenance; But tape are susceptible to wear and tear, and the slope is not too big, high friction, easy to pollute the environment and transporting powdery and granular materials, so this design can reduce the environment pollution, and reduce the friction to avoid excessive wear of belt. At the same time in developing the conveyor level have obvious improve, high power, long distance belt conveyor of new technology and new product development research have made great achievements. The belt conveyor is one of the most ideal efficient continuous transportation equipment, compared with other equipment has obvious advantages. Therefore, not only can be used in short distance transportation, also can be used in long distance transmission. So in the continuity of production and has played a very important role in automation, improve the labor productivity.
key words:asking the rod; totally closed; bringing type conveyer; spiral to strain strain the device.
