- The task of this graduation project is " The weighing belt feeder " , be living in the specification book , and introduced the detailed composition that the different part of meritorous service of installation be able to reach the distinguishing feature completees such meritorous service capacity but is underway every section .
Being living thoroughly to comprehend the style brought calls severely to give to anticipate that the wide-ranging use reaches such is living significant action queen in the middle national economy development to engine , unite specially having something to do with the teaching material , the design come out this task “weighing belt feeder ”.
The weighing belt feeder is used for continuous bulk material feeding and measurement. It is simple-structured, convenient to operate, reliable, and needs less maintenance. It is widely applied to industries such as metallurgy, power supply, chemistry, coal mining, warehousing, etc. It can be used independently or together with the others.
The style brought is called severely being anticipateed that the engine consists of that the style brought conveyer and the electron calculates two sections .
Being living in the specification book detailedly to introduce is anticipateed that engine every section is makeed up the meritorous service capacity .
As a result of native is designed to emphasize to machine designing , therefore in accordance the national standard assists to the calculating machine drawed the inflexible drawing that general drawing amount balancees 2.5 .
Components picture and part drawing and so on that possess the general assembly picture and main .
Finally native is designed still giving out design produce installation , debug and protection respect demand together with general knowledge , and feeies that public figure refers to inner place the profession .
Native is designed except for is living the somewhat innovation on the composition inheritance but also rule which developed in line with not only , and see also relevant specialized dissertation and the book moreover .
Keywords: weighting、belt conveyor
