Applying structural theories of series connected robot, the joint coordinate series connected robots were finally determined as the design scheme. The basic structural parameters of stowage equipment of cotton bundle were determined on the result from workspace of clamp compared with the room which the stowage was occupied. The controlling arithmetic of stowage equipment of cotton bundle was inferred and educed, which had built the foundation of automatization of system.

Basing on confirming the structure parameters of relative components and simulation, movements of material on the sieve were analyzed, and then put forward one new-style structure of sieve. According to every point’s kv and movement locus on the sieve, figure equation of whole sieve was found. The optimal figure of sieve which is fit for the filtration and transportation was acquired. Through analysis and computation, material’s transportation velocity was achieved, and checked out the material transportation efficiency furthermore.
