Abstract Along with the modern factorization agricultural technologydevelopment, the factorization highly effective agriculture therequest which grows seedlings to sowing seeds more and more high, isurgent needs to study the design to suit our country nationalcondition the mechanization to grow seedlings the equipment. Thisarticle the quantity seeder performance obtains from entire MiaoPanjing, the research designed has been automatic, in thesemiautomatic system earthen bowl machine fine broadcast theinstallment the structure composition, It contains a fixed platoon kind of board and the active cloth plantsthe board and brushes plants the wheel. Has studied the row of kind ofdesign parameter to its sowing-drill performance influence, andplanted the board to a fixed platoon kind of board and the activecloth and brushes plants the wheel related parameter the selection tocarry on the theoretical analysis design, and carried on theexperimental confirmation in the self-made test platform. Establishesthe different condition the mathematical model, to the orifice holediameter and the altitude, brushes plants the wheel diameter and thetravelling speed, The rotation speed and the cloth plant and the clear kind of functioncarries on the theoretical analysis and carries on the confirmationwith the experiment, has designed the hole diameter and the altitudeaccording to the theory and the test result, brushes plants the wheeldiameter, determined brushes plants the wheel speed parameter. Inorder to cause the sowing-drill performance to be more perfect, hasdesigned a structure simple force row of kind of equipment. Entiremachine structure simple, becomes the background, the ease ofoperation, is good after the confirmation work effect, greatlyincreased the sowing seeds precision and the efficiency, remarkablyreduced the labor intensity.
