4h-2型花生收获机的设计原理及运动特性分析外文翻译(编辑修改稿)内容摘要：

logram mechanism, therefore harvest parts 10 and 13 swing with erect axis 4 and 9 with the same frequency and angle but contrary direction. The working process is: the scoops 10 and 13 digging the peanut out and moving the peanut backward, while the lengthways grids continuously make the fanlike swing, and then break the admixture of soil and peanuts. By this movement the heavy soil sinks down via the grids, and the lighter peanut moves up, so that peanut is separated from soil well. The peanut is moving rearward continuously, finally even laying on the excavated ground, so it is convenient for manual collection. 3： Function characteristics of the harvester The swingdigging principle and the inverse parallelogram mechanism have been successfully created and applied to 4H2 type peanut harvester. It had broken the traditional way which is scoop and separate chain to bine together for harvesting. (1) 4H2 type peanut harvester should be matched with the small fourwheel tractors which are very universal. Its design is reasonable, with reliable working, steady function, convenient adjustment, higher adaptability, and this machine can work in various fields and harvest all kinds of peanut. (2) In harvesting process, plastic film was not broken and easy collected with the peanut stalks. There is none leavings of them on the ground. (3) As created the swingdigging principle, the whole resistance and the power consumption of the harvester have been reduced. By means of the swing function, the soil with heavy specific gravity sinking passes through the grids, and the peanut with lighter specific gravity moves up, so that the loss rate of peanut was reduced remarkably. 4H2 type peanut harvester is the new typical agricultural implement for the small scale farms of China and more suitable for Chinese peanut production. This harvester has the simpler structure and lower price. Its various performance in。
