Cattail Chopped Structure Optimization Design

Rushes has the strong toughness,high cellulose content,can absorb nitrogen in water,phosphorus and heavy metals and other characteristics,in recent years has been widely used in environmental protection sewage remediation project,Pucao breeding fast,easily overrun,rushes are cut into 10 ~ 20 mm spacing length to anaerobic fermentation to produce biogas is cattail resource use one of the most direct and effective method.Because of its strong toughness,rushes to shredding device need to put forward higher requirements,the general forage chopping blade can not meet the requirements of cattail chopped,to optimize the structure of chopping device in a chopping blade through to meet the needs of cattail chopped.Simulation-X section increasing,dynamic analysis,through the research in this paper mainly in Yunnan Tong Hai rushes chopper chopper prototype on the cutting principle,chopped mode choice,choose to use round knife type cutting through the conventional blade: straight edge blade,curved blade blade sliding cutting angle blade chopped performance analysis that the sliding cutting angle of 35 degrees to 45 degrees.With the sliding cutting angle of the movable blade cutting torque is reduced the chopped energy consumption is low,put forward a kind of change and corner cutting knife,a cutting slip sliding cutting angle in 35 degrees to 45 degrees,through the use of SolidWorks software in the plug-in Rushes for sliding cutting,accepting,press straight edge blade,curved blade blade sliding cutting angle of the blades and the new proposed sliding cutting angle blade static stress simulation analysis in the same external loads,sliding cutting blade stress and deformation ratio,minimum safety coefficient and displacement for four blade is the lowest,the straight edge arc blade sliding cutting angle cutting average torque analysis using the lowest energy consumption for variable slip to slip cut to provide strong support for the average cutting torque is the energy consumption and the static stress simulation analysis of variable sliding cutting angle of the knife chopped best blade.The PU The grass cutting device can be optimized,and opens up a new way for high resource utilization.
