大豆玉米间作播种机设计稿与传动计算毕业设计稿专业论文78203553.docxVIP

本科生毕业论文（设计） 题 目大豆玉米间作播种机设计与传动计算摘要 间作套种能够充分利用空间和边行优势，提高土壤养分，增加作物的抗逆能力，提高土地利用率和单位面积产量。虽然市场上播种机的种类繁多，但缺乏针对大豆玉米间作套种的播种机。为了解决大豆玉米间作套种种植的问题，我们研究和设计了大豆玉米间作播种机。本文设计的大豆玉米间作播种选择了转仓式精密排种器，锄铲式开沟器和带有轮刺直径较大的地轮，播种机整机采用了地轮后置单体式，并进行了地轮轴和中间传动轴设计；在传动设计计算中主要论述了播种机1级、2级传动计算和链轮的设计。大豆玉米间作播种机与传统的播种机相比，新颖之处在于播种机可以同时播种玉米、大豆和为了防止地轮的滑移，采用了4个地轮共同带动中间传动轴，保证播种机精密播种质量。设计中在考虑实用的同时，兼顾经济节约，从而达到结构合理、生产成本低目的。该机一次作业可完成破茬开沟、播种和镇压等工序，作业时开沟均匀，播种作业质量高，可满足黄淮海地区农艺要求。 关键字：大豆；玉米；间作；播种机；传动设计 The Design and Transmission Calculation of Soybean-corn Interplanting Seeding Machine Abstract Intercropping can make full use of space and edge line advantage, improve soil nutrient, increase crop resilience and improve the land utilization rate and yield per unit of area.Although the market of the machine various, but it is lack of soybean-corm interplanting seeding machine.In order to solve the problem of soybean-corn interplant, we researched and designed soybean-corm interplanting seeding machine. 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 wheel.This paper have designed the axle and the middle transmission. In the chapter of transmission design and calculation, It mainly discussed the first and second line could drive calculation and the design of the chain.Compared 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 economy.This planter can perform the roots talk cutting ,opening,sending and packing operations once.
