虾蟹池塘水草收割打捞工艺研究

Harvesting process of aquatic for shrimpcrabpond

摘要:

为了满足虾蟹养殖塘对水草密度的要求，需对塘内水草进行定时定量的去除打捞。在对传统人工收割打捞和河道清草机分析的基础上，提出虾蟹塘水草收割打捞工艺，根据实际生产需求提出一体化打采式水草切割打捞装置方案，并对该装置主要工作部件的尺寸、转速等参数提出要求。运用流体有限元分析软件FLUENT对滚刀进行力学分析，得到打采滚刀轴向力和扭矩。装置采用滚刀打采，螺旋输送式打捞收集，实时脱水。系统结构简单，操作灵活方便，工作连续稳定，省却抽吸泵设备，适应较恶劣的作业环境，抗堵性能强，作业性能稳定，劳动强度低，效率高，满足了淡水养殖业对水草打捞装备成本低、拆装方便等实际需求。

Abstract:

To satisfy the requirement of density of aquatic for shrimp and crab pond aquaculture, the aquatic should be cut periodically. Based on the analysis of traditional manual reaping and river cleaning equipment, a whole new plan for reaping aquatic in shrimp and crab pond and designs of aquaticcuttingharvesting equipment have been proposed. Furthermore,demands were made on the size and data of exact dimensions and other important parameters of main working parts, which were based on the actual production needs. Hub cutter is analyzed by CFD software FLUENT in order to get the integrative data about in the field of dynamic pressure. The equipment is set to use cutter and worm conveyer with easy geometry, dehydrating in real time, without pumps, with good stability, high efficiency and adapting to any kinds of difficult working environments. Such equipment satisfies the needs of low cost,easy for assembling proposed by the actual demands.
