Design And Study On Straw Briquetting Equmipment

This article has made a brief outline to the theoretical investigation about biologic straw stalk solidify shaped. And introduce the meaning for developing briquetting straw fodder. I take an aim at the design of straw(feedstuff)briquetting machine, and determine the integrated design scheme for briquetting machine.The hydraulic pressure system was counted in detail, and the basic parameter of it was determined. According to designing conceive, principal part was designed which was named compressing room. I determine parameter of the compressing room, and establish three-dimensional entity model for every part. The mechanism was assembled with part models.The model of compress room was analyzed with the finite element software Cosmosworks which was a plug-in of Solidworks. According to practical situation, I defined constraints and loads for finite element analysis. Analyzed stress distribution and distortion of the model. Aim at the shortcomings, I improved the design. The improved model was analyzed with static analysis and fatigue analysis to make sure that the stress deformation and fatigue failure within the permit area.I designed the mechanism for closing and unclosing in biomass briquetting machine in this article,two design schemes were contrived for the mechanism. The original Scheme based on the theory of existing equipment, which used hydraulic cylinder directly action to the covering for closing and unclosing. The basic parameters were determined for it. Base on the parameters I establish three-dimensional entitative model for the mechanism, and analyzed it with Cosmosmtion for computer simulation.The improved scheme adopt crank and rocker mechanism for lock and unlock the covering, hydraulic cylinder powered for this mechanism. The covering will be more stable when the dead point appears. Hydraulic cylinder principal overcome the gravitation and friction. The acting force was little, so we can decrease the parameter of hydraulic cylinder for cost cutting.I designed this crank and rocker mechanism with auxiliary circle, the parameters of the crank and rocker mechanism were counted,such as minimum transmission angle and pressure angle. I simulated the two schemes with computer simulation software, and output the result curves and cartoon.
