Study On The Design Of Tobacco Pneumatic Drum Seeder

As the technology of tobacco floating system was applied and promoted athome and abroad， and with the rapid development of industrialized seedingcultivating，in order to achieve the mechanization of tobacco plug precision seedingand satisfy the need of industrialized seeding cultivating technology, based on theanalysis of the existing precision machine, this paper proposed a technology ofpneumatic-drum seeder and the manufacturing of prototype Was performed．Besides，the tobacco seeds pelletization machine equipment Was studied．Centered on the topic research of the pneumatic-drum seeder, this paper finishedthose tasks，listed bellow．(1) The development course of tobacco planting technology and seeding machinewas briefly introduced，so Was the tobacco floating system．The structure and workprinciple of various types of machine applied to the tobacco factory precision seedingwere studied．And the inadequacies and development tendency of the precisionseeding was analyzed．(2)The processing of pelleted tobacco seeds Was introduced， the materialcharacteristics including particle size distribution,1000grains weight, pelleted rate,seed containing rate, single seed rate, splitting decomposition degree were introduced.References and patent literature, we propose two pneumatic drum plug planter designand structure of the two principles was discussed drum plug seeder.(3)Over several scenarios contrast, pneumatic drum seeder to get the final design,introduces the structure and working principle of the planter, and draw the design withCAD drawings, solid-works three-dimensional modeling, UG dimensionaloptimization simulation. Through theoretical calculations and technical parameters ofthe three-dimensional virtual simulation of pneumatic roller drum plug tobaccoplanter set of key components, published patent.(4)Experimental prototype produced.by pressing the test point is determined in theroller tube to pass into0.15Mpa of gas pressure when speed is7r/min planter is best.By theoretical analysis, to determine the reasonableness of the three-dimensionalsimulation optimization Pneumatic plug tobacco planter, is required for thedevelopment of innovations suitable for intensive tobacco.
