In this paper， the machine chose warehouse type precision seed metering device, Shovel type ditcher and the larger diameter land wheel with having thorn,This seeding machine adopts the rear paper have designed the axle and the middle transmissio n. In the chapter of transmission design and calculation, It mainly discussed the first and second line could drive calculation and the design of the with the traditional machine, this machine can sow corn and soybean at the same time. In order to prevent land wheel slippage, we use the style of four land wheel driving transmission shaft. Considering practical at the same time, it take account of economic planter can perform the roots talk cutting ,opening,sending and packing operations once. Key Words： soybean。 本文設(shè)計的大豆玉米間作播種選擇了轉(zhuǎn)倉式精密排種器，鋤鏟式開溝器和帶有輪刺直徑較大的地輪，播種機整機采用了地輪后置單體式，并進行了地輪軸和中間傳動軸設(shè)計 ；在傳動設(shè)計計算中主要論述了播種機 1 級、 2 級傳動計算和鏈輪的設(shè)計。 本科生畢業(yè)論文（設(shè)計） 題 目 大豆玉米間作播種機設(shè)計與傳動計算 摘要 間作套種能夠 充分利用空間和邊行優(yōu)勢， 提高土壤養(yǎng)分 ， 增加作物的抗逆能力 ，提高土地利用率和單位面積產(chǎn)量。 大豆玉米間作播種機與傳統(tǒng)的播種機相比，新穎之處在于播種機可以同時播種玉
