摘要:土豆是一種世界性的經(jīng)濟作物，也是一種重要的化工原料。它是我國主要經(jīng)濟作物之一，在我國各地均有栽培，種植面積居世界第二，產(chǎn)量居世界之首，一年四季均有收獲。隨著農(nóng)業(yè)產(chǎn)業(yè)結(jié)構(gòu)的調(diào)整和產(chǎn)業(yè)道路的實施，土豆種植面積穩(wěn)中有增。土豆收獲作業(yè)勞動量大，耗時費工，實現(xiàn)機械化收獲是其必然方向。近年來，土豆收獲機械的研制與推廣有了較大發(fā)展。目前國內(nèi)機型以小型、配套動力小、結(jié)構(gòu)簡單、輕便為主。但由于土豆莖桿的存在，在收獲過程中不得不先除去莖桿，這樣又加大了勞動強度，也使得研制機具的技術(shù)水平與國外相差甚大，嚴(yán)重制約了土豆產(chǎn)業(yè)化的發(fā)展。為了減輕農(nóng)民的勞動強度，節(jié)約時間，通過對國內(nèi)外具有代表性土豆收獲機械的研究和討論，對比它們的結(jié)構(gòu)和工作特點的基礎(chǔ)上確定了一種新型土豆聯(lián)合收獲機械的莖薯分離與起獲設(shè)計方案。實現(xiàn)莖薯分離后土薯進(jìn)一步分離并將土豆均勻的鋪放于本隴，不影響下一隴的繼續(xù)作業(yè)，而且便于撿拾，從而減輕了土豆收獲的勞動量，提高勞動生產(chǎn)率。 關(guān)鍵詞：土豆；莖薯分離；聯(lián)合收獲機
Abstract:Potato is a kind of worldwide economic crop, also is a kind of important chemical raw materials. It is our country one of main economy crop, planting spread all over the country, cultivate an area to reside the world the second, output ranks first in the world, all the year round all the harvest. As the adjustment of agricultural industry structure and path of industry implementation, potato planting area is firm in have add. Potato harvesting large amount of labor, time consuming and labor, realize harvesting mechanization is the inevitable direction. In recent years, the potato harvesting machinery research and promotion had greater progress. At present the domestic models with small, small matched power, simple structure, the main light. But as a result of potato stem exists, in the harvesting process to remove stalks, and increase the labor intensity, also makes the development of equipment technology level and abroad also differs very big, seriously restricting the potato industrialization development. In order to reduce the labor intensity of farmers, saving time, through to the domestic and international representative potato harvesting machinery research and discuss, in contrast to their structure and work characteristics were determined on the basis of a new potato harvester stalk separation and recovery design of potato. Realization of potatoes from potato stem after further separated and potatoes evenly laid on the long, not under the influence of a long continuous operation, and is easy to pick up. In order to reduce the potato harvesting of labor, improve labor productivity. Keywords：Potato; Stem tuber separation; combine harvester |
