一种牧草搂草机的总体设计
摘 要
中国草原辽阔，草资源丰富，但草原畜牧业仍然没有摆脱靠天养畜的落后状况。由于牧草收获机械化水平低，不能及时有效地收获并贮存足够的牧草供应牧畜越冬。随着中国西部大开发战略的实施和生态环境保护政策的落实，促进了生态保护和恢复草原,促进了草原改良、退耕还草、沙漠整治等工作，再加上人们对各种畜产品需要量急剧增加,这必将推动和加快牧草机械的发展,促进草业机械化水平的提高，从而使牧草产业成为集态、经济和社会效益于一体的新型综合性产业。搂草机必将得到广泛的应用和推广。本文综述了国内外搂草机的研究现状，包括横向搂草机、侧向搂草机、滚筒式搂草机、指轮式搂草机、旋转式搂草机，分析了它们的技术特性与工作结构，在这基础上提出了我国搂草机与国外差距所在。

Overall design of a kind of grass rake
ABSTRACT
Chinas grasslands is vast, grass resources are rich, but still not get rid of the backwardness of depending natural to feed animals. Due to forage harvesting mechanization level is low, not timely and effective to harvest and store enough of doing so by winter forage supply. As Chinas western development strategy implementation and fulfill the policy of ecological environmental protection, promote the ecological protection and restoration of grassland, promoted the grassland improvement, farmland and grassland, desert control, such as work, coupled with the sharp increase in demand for all kinds of animal products people, it will promote and accelerate the development of forage machinery, promote grass industry to raise the level of mechanization to forage industry become a state, economic and social benefits in one of the new type of integrated industry. Rake will get extensive application and promotion.This article summarized the domestic and foreign research status quo of rake, including horizontal rake, lateral rake, cylinder rake, refers to the wheel rake, rotary rake, analyzed their technical characteristics and working structure, based on this, advances the rake in our country and foreign gap.
Key words:Hay rake; Forage harvesting mechanization; Forage industry;
