摘要

花生是传统的农作物，可以进行多种类深加工，现在花生产品和农业结构调整已经变成我国重点种植的农作物，其加工产品远销世界各地，在这种广阔的发展前景的推动下，花生生产势头猛涨，并有逐渐集中生产的趋势，一套成熟的产业链已经形成。然而中国花生生产机械化发展却严重阻碍了花生产业的发展，传统花生收获主要依靠人工完成，劳动强度大、作业成本高、效率低、损失大，这些问题已经严重制约着其产业的长足发展。本论文设计了振动筛式花生收获机的总体结构、工作原理、技术特点以及关键部件结构与工作参数设计等。该设备主要由挖掘铲、振动筛、行走轮、动力传动装置及机架等组成。此机械设备工作顺畅运行可靠，生产率：0.1～0.13hm2/h，荚果破碎率：≤1%，清土率高，损失率低,损失率：≤3%,，适用于个体较大规模的机械化生产，解放劳动力。

Abstract

Peanut is traditional plant, has become China's important export products and focus on the development of agricultural restructuring and support the cultivation of varieties. In the consumption structure and export structure adjustment and optimization of dual-drive, the rapid development of peanut production, and gradually the relative concentration of the main producing areas, with the basic formation of competitive industries. However, peanut production mechanization in China are seriously lagging behind, especially in the whole process of production, operating costs account for the production of harvesting operations, mainly rely on manual completion of the current, labor-intensive, operating costs are high, low efficiency, loss, and the high cost of development and production has become a major bottleneck in the growth of industry, mechanization of domestic peanut harvest technology and equipment needs of the increasingly urgent introduced a shaker-style peanut harvester of the overall structure, working principle and technical characteristics of the key components of the structure and design operating parameters. The device mainly by the mining shovel, vibration screen, vibration-drive components, running wheel, power transmission and chassis components, etc., two lines of a complete peanut harvesting, dug out the peanut seedling was sent to the shaker, after the vibration shaker to remove excavated soil associated with the peanut, and finally through the transportation board to achieve the side of peanut seedling lodging works. It has a smooth operation, Productivity:0.1~0.13hm2/h,Pods and broken rate: 1%,A high rate of soil, low loss, loss rate: 3%,reliable operation, high rate of land clearance。

Keywords: Vibrating screen; Parallel link; Digging shovel; Belt wheel
