Every year because of the harvest of crops will produce a large amount of straw . Straw is also a renewable resources Many kinds of straw, including cotton, wheat, corn, rice and soon. The texture isnot a straw, no unified research, taking wheat straw as the research object. The study of the straw packer has already existed for several decades. Most of the domestic main are from the fields, from the scene of the straw and then packaged . pression molding as feed or fuel, and bine collaborative package pression molding .Therefore, the study bination bine harvester pressed into an available building materials of packaging machine with the objective necessity. Straw bale is mainly based on the straw bale design principles of structural design . Due to the installation in bine harvester, must optimize the layout. pression molding adopts hydraulic forming structure .Including crushing structure, packaged into block, compression molding mechanism. Detailed calculation of anization .In the crushing mechanism, the throwing knife is used, and the throwing plate is added .It is crushing process, crushing uniform, mechanism simple .Packed into blocks by hydraulic means, simple mechanical structure, pression effect is ideal. Because straw bine cooperative effect, wide application prospect .You can efficiently crush, transmission, compression molding, packaged
