Mechanized conservation tillage technology and the key is to promote the development of notillage planter. At present, the existence of notillage planter in the development of the core problem is the congestion problem of notillage planter. In spite of agricultural experts in the development of notillage planter has made some achievements,requit theblocking used methods and different types of protective devices, but they can not fundamentally solve the problem. This article is starting from this issue will be reseeder the drilling hole seeding, soil working parts of the work (by the trencher39。s moving into a hilldrop39。s rotation), to solve the congestion problem. Learned in recent years, hilldrop planter planted in plastic film experience, to optimize existing models and improve to meet the requirements of the status of free land. To this end, the design of mechanical hilldrop planter people to better adapt to the requirements of farmers. Sluicegate mouth in order to ensure the activities of institutions to adapt to different conditions, to study and design of a cam Rockerstyle forced open the body. Hilldrop bined with the characteristics of round work, select check box device was developed to be patible with the volume of broadcastconditioning, to meet different user requirements of the volume of different sowing increased minutes, filling efficiency. Finally, the analysis of the cavitation mechanism works, the identification of key operating parameters.Key words：wheat bunch planting machine。 hilldrop driver。 bunch planting machine configuration。 cavitation device。 metering device致謝本次設(shè)計是在張鋒偉老師的悉心指導(dǎo)與嚴(yán)格要求下進(jìn)行的。從設(shè)計（論文）的選題、方案的設(shè)計、具體的測繪與繪圖到論文撰寫的每個環(huán)節(jié)，都凝聚著導(dǎo)師的心血和汗水。導(dǎo)師嚴(yán)謹(jǐn)?shù)闹螌W(xué)態(tài)度、開拓創(chuàng)新的工作作風(fēng)及對事業(yè)的奮進(jìn)執(zhí)著精神，都將使我銘記在心，并時刻激勵著我不斷追求勇往直前。再次，我還要特地感謝我們班的同學(xué)。他們在我完成本設(shè)計的過程中給我了許多幫助和寶貴的意見。值此論文完成之際，謹(jǐn)向所有關(guān)心、支持和幫助我的老師、同學(xué)和朋友表示最衷心的感謝！30
