The output of Chinese cotton is around500million tons, value of one is750billion yuan or so. More than200million farmers are directly involved in cotton production. The cotton processing industry moves forward a big step from the semi-mechanization to modern mechanization. It is imperative to replace manual operations by mechanized production in the torrent of the development. But most of the cotton processing plants feed seed-cotton with suction tube in XinJiang after artificial picking stack basically. Especially with the advent of efficient cotton gin, artificial feeding cotton has failed to meet the progress and development of the cotton processing industry.In this paper, the inspection and absorption of domestic and foreign data of feeding cotton machinery make it possible to put forward to the overall design, which is a automatic feeding machine used for pulling down cotton, picking cotton, conveying cotton based on the theory of mechanical design and virtual design knowledge. A whole support structure consists of pulling down cotton frame and picking-conveying cotton frame. Pulling down unit includes pulling down cotton frame and pulling down roller. The roller can swing with the frame up and down. Picking up cotton roller and spiral conveyor connect with picking-conveying cotton frame. Pulling down cotton roller, picking cotton roller and spiral conveyor are driven by hydraulic unit. The size parameters of the key parts can be identified. Three-dimensional modeling of automatic feeding cotton is established by UG NX6.0. Then the use of NX Motion Simulation analysis module make motion simulation for pulling down cotton unit and picking-conveying cotton unit of automatic feeding machine.Analysis of simulation results can be obtained. The working height of pulling down cotton roller is5216.86mm, the turning angle of pulling down cotton arm is94.83°, the machine moving forward can be elevated146mm. Hydraulic cylinder piston rod of the pulling down arm can subject to the maximum force54720N, the lower part of the hydraulic cylinder piston rod can subject to the maximum force20900N. Compared the results of the analysis with the previous theoretical calculations, the initial design could meet the requirements.NX Motion Simulation module is used to predict engineering application. In other words, before automatic feeding cotton actually produced, the software can predict movement characteristics. These forecasts are based on very complex mathematical theories and recognized the physical and engineering principles. Motion simulation results can provide a theoretical foundation shorten design cycle.
