【摘要】：针对农村畜禽养殖造成的环境污染问题,设计一种可快速拆装车载式农家肥捡拾装置,对其核心部件集送搅龙作机理分析与参数优化。通过分析装置使用环境特点及技术要求,综合物料受力及运动分析确定基础参数及结构,使用CATIA(Computer aided three-dimensional interactive application)作三维模型及数字样机构建;以搅龙螺旋直径、收集搅龙螺距以及搅龙主轴转速为变量,输送量与功耗为响应指标,作二次正交旋转组合EDEM(Engineering discrete element method)虚拟仿真试验。针对5 t·h~(-1)设计指标,理论分析与仿真获得搅龙参数组合为:搅龙螺旋直径200 mm、提升搅龙螺距160 mm、收集搅龙螺距120 mm、搅龙主轴转速107 r·min~(-1),功耗1.118k W。样机试验结果表明,分段式集送搅龙总体技术方案以及快速拆装形式可满足农家肥捡拾需求,具有良好使用环境适应性,研究为搅龙机构拓展应用提供借鉴与参考。
[Abstract]:In order to solve the problem of environmental pollution caused by livestock and poultry farming in rural areas, a kind of picking device of farm manure can be quickly disassembled and assembled, and the mechanism analysis and parameter optimization of its core components are analyzed and optimized. Based on the analysis of the environmental characteristics and technical requirements of the device, the basic parameters and structure are determined by synthesizing the material force and motion analysis, and the 3D model and digital prototype are constructed by using CATIA (Computer aided three-dimensional interactive application). Taking the screw diameter of the stirring dragon, collecting the pitch and the rotation speed of the main shaft of the stirring dragon as the variables and the quantity and power consumption of the conveyer as the response index, the virtual simulation test of the quadratic orthogonal rotation combination EDEM (Engineering discrete element method) is made. According to the design index of 5 t h-1, theoretical analysis and simulation results show that the mixing parameters are as follows: screw diameter 200 mm, pitch 160 mm,. The rotation speed of the main shaft is 107r min~ (-1), and the screw pitch is 120 mm, the main shaft speed is 107r min~ (-1), and the rotation speed of the main shaft is 107r min~ (-1). The power consumption is 1.118kW. The results of the prototype test show that the overall technical scheme and the rapid disassembly and assembly form of the segmented gathering and feeding dragon can meet the needs of picking up farm manure and have good environmental adaptability. The study provides reference and reference for the development and application of the dragon churning mechanism.
