The Design And The Key Components Research Of A Joint Machine For Straw Collection-Crushed-Molded

With the process of using crop stalks accelerating,the demand for straw is also increasing,how to combine abandoned crop stalks quickly after harvesting mechanically instead of doing this by people and increase the density of the straw after collection,reduce storage space and transportation costs are the bottleneck of the current use of straw in China.This article is adapted to the actual needs of our country and conduct research:Trying to develop a new type of straw collection and processing technology and equipment that can be to collect the straw and smash it and then compress it in the field full automatic.It transfers the straw to the commodities in the field a one-time.The whole process takes only one person to operate,greatly reducing the cost of collecting the straw to make straw resources to truly realize the industrialization and commercialization and high value-added utilization.This paper studies the principle of "use the advanced automation equipment to replace expensive labor to collect the straw efficiently and process it of high-density" to design a machine that includes collecting,grinding,molding.It can produce biomass with the density of 1.2kg/m3 in the field.Firstly,through the research in the farm in Fujin,determining the status and harvest moisture content of the straw,And compare with the existing collection devices,highlighting its advantages.Lay the foundation for the design of a joint machine for straw collection-crushed-molded;Determine the overall scheme of the combined machine,Short-quit-circuit institution can stalk close to the ground to pick up,shake the soil and rapid transport backwards,Auxiliary pickup pick up work completed straw,Significantly reduce the rate of leakage pickup;Through the establishment of Tine pickup rollers and short quick delivery mechanism of the main components of the mathematical model,Tine pickup roller is a,Oscillating follower disk cam mechanism after inversion",short circuit quick transport mechanism in the form of a parallelogram structure.Using ADAMS software delivery mechanism for short circuit fast kinetie analysis,And draw trajectory of a little elliptical to meet the requirements of the pickup.Use the three-dimensional software SolidWorks to three-dimensional modeling of the parts of the joint machine.Use of the fitting portion of the software to assemble the automatic pick and pretreatment system;Using ANSYS Workbench 12.0 static core components of finite element analysis to verify that it meets the design requirements of strength and stifness,Modal analysis results of automatic straw collection-crushed-forming joint machine does not produce a resonance phenomenon of the parts during operation.It cari achieve safe production,Lay a theoretical basis for a joint machine for straw collection-crushed-molded optimized design.
