4LBZ-100型水稻收割機脫粒裝置改進設計（全套含CAD圖紙）

摘 要收割機的發(fā)展方向?qū)⑹窍蚋呖萍蓟较虬l(fā)展，制造出適用性強的收割機很有發(fā)展市場，對不同地區(qū)開發(fā)出不同的收割機是很有發(fā)展前途的。由此，相應的制造出高性能的水稻收割機是國外收獲機的發(fā)展概況。該水稻水稻收割機可一次性完成收割、脫粒、分離和裝袋作業(yè)。該機體積小、重量輕，操作靈活，通過性與適應性好，較好地解決了大、中型收割機在丘陵、山區(qū)和水田難以收割的難題。關鍵詞：水稻脫粒裝置；脫粒； 改進設計AbstractThe development direction of harvester will be to high-tech direction, making out the applicability of harvester is the development of the market, is very promising for different regions developed different harvester. Thus, the corresponding manufacturing combine high performance is the development of foreign harvester. The rice combine harvester can complete harvesting, threshing, separation and bagging operations at one time. The machine has the advantages of small volume, light weight, flexible operation, through and good adaptability, can better solve the problem of big, medium-sized harvester to harvest in the hilly, mountainous and paddy field.Key Words: rice thresher threshing; improved design;結論目 錄摘 要
