1、黑龙江工程学院本科生毕业设计附 录Seeder history and introductionhe first century B.C., China has good, this is to promote the use of the worlds earliest drill machine, today is still in the north of equal applications. 1636 in Greece first Taiwan machine made. In 1830, russians in livestock HuaLi more on LiBo machi
2、ne made. 1860 years later, the countries such as Britain and started mass production work grain suitable drill. After the 20 th century have appeared traction and hanging drill machine, and the use of grain strength of the machine. 50 s development precision machine. China from the 1950 s to introdu
3、ce grain suitable drill, cotton machine, etc. 60 s has developed into a suspension type grain machine, centrifugal machine, universal frame and gas suction style such as machine machine DuoZhong type, and grinding lines to the development of the device. In the 70 s, has formed the seeding machine ge
4、neral machine and grain joint seeder two series, and has developed precision machine. Europe first Taiwan machine made in 1636 in Greece. In 1830, the russians in livestock HuaLi more on the sowing device LiBo machine made. Britain, the United States and other countries in 1860 years later started m
5、ass production work grain suitable drill. 20 centuries later period, there appeared the traction and hanging drill machine, and the use of grain strength of the machine. In 1958, Norway appear first Taiwan centrifugal machine, 50 s gradually developed all kinds of precision machine. China in the 195
6、0 s introduced from abroad grain suitable drill, cotton machine, the 60 s and has successfully developed suspension type grain machine, centrifugal machine, universal frame and gas suction style such as machine machine DuoZhong models, and has developed grinding lines of the device. In the 70 s, has
7、 formed the seeding machine general machine and grain joint seeder two series and production. For grain and intertillage crops, grasses, and all kinds of vegetables with suitable drill and XueBo machine are already widely used. At the same time, also has developed DuoZhong precision machine. Corn is
