【摘要】：现阶段,秸秆物料的回收利用,已成为势不可挡的话题。秸秆过度还田利用,不利于田间作物的生长;田间秸秆燃烧则成为农村以及城市环境保护的罪魁祸首。因此有效地对秸秆再利用有利于环境的治理而且可以变废为宝,秸秆物料不仅可以用来制成固体燃料、气化炉燃、立体栽培草腐类食用菌、人造板、生物柴、压块燃料或秸秆压块饲草等,那么秸秆的回收就成为秸秆再利用的重要一步,因此秸秆打捆机的研制具有重要意义。旋转切割喂入装置是打捆机的重要部分,优秀的旋转切割喂入装置不仅可以提高收获效率,降低机械的故障,而且可以有效地将秸秆物料切断,减少秸秆再利用收获工艺的步骤,切段揉碎的秸秆物料有利于牲畜的消化吸收、增大喂入量、增加草捆密度、秸秆物料的存贮,因此,旋转切割喂入装置的研究设计与优化具有较大的研究意义。本课题通过研究旋转切割喂入装置的结构、工作原理、运动分析,可以充分地了解旋转切割喂入装置。针对主要机构,对其零部件进行力学分析与机构研究、有限元分析优化是十分有必要的。玉米秸秆是北方最为常见的农作物,为了更好地使用旋转切割喂入装置,通过室内试验与田间试验,确定了旋转切割喂入装置针对玉米秸秆最优前进速度与传动轴输出转速,同时验证了旋转切割喂入装置对秸秆切段长度与理论切段长度的吻合程度。通过对旋转切割喂入装置进行研究、分析,有效提高了旋转切割喂入装置的使用寿命与使用效率,更深入地掌握旋转切割喂入装置的构成与工作原理,为今后旋转切割喂入装置的改进与创新提供基础性研究。
[Abstract]:At present, the recycling of straw materials has become an irresistible topic. The excessive utilization of straw is not conducive to the growth of field crops, and the burning of straw in the field has become the chief culprit of environmental protection in rural and urban areas. Therefore, the reuse of straw is beneficial to the treatment of the environment and can be turned into a treasure. The straw material can not only be used to make solid fuel, gasifier combustion, stereoscopic cultivation of grass rot edible fungi, wood-based panels, biological firewood, So the recovery of straw becomes an important step of straw reuse, so the development of straw strapping machine is of great significance. The rotary cutting feeding device is an important part of the strapping machine. The excellent rotary cutting feeding device can not only improve the harvesting efficiency and reduce the mechanical failure, but also effectively cut off the straw material. In order to reduce the process of straw reuse and harvest, the chopped straw material is beneficial to the digestion and absorption of livestock, the increase of feed amount, the increase of density of straw bundles and the storage of straw materials. The research, design and optimization of rotary cutting and feeding device are of great significance. By studying the structure, working principle and motion analysis of the rotary cutting feeding device, we can fully understand the rotary cutting feeding device. The finite element analysis and optimization is necessary for the mechanical analysis and mechanism study of the main mechanism. Corn stalk is the most common crop in the north. In order to better use the rotary cutting feeding device, through laboratory and field experiments, the rotation cutting feeding device is determined to optimize the advance speed of corn straw and the output speed of the transmission shaft. At the same time, the degree of coincidence between the cutting length of straw and the theoretical length was verified by rotating cutting and feeding device. Through the research and analysis of the rotary cutting feeding device, the service life and efficiency of the rotary cutting feeding device are effectively improved, and the composition and working principle of the rotary cutting feeding device are more thoroughly grasped. It provides basic research for the improvement and innovation of rotary cutting and feeding device in the future.
