摘要:
针对人工收蛋环境脏乱差、强度大、效率低、成本高等问题,以及市面现有鸡蛋降落装置需淘汰原有鸡笼,增加投入成本、结构复杂、占地面积大等现状,设计了一种阶梯式鸡蛋降落装置,该装置结构简单、设计合理,在配合收蛋器进行收蛋作业时,可对鸡蛋提供较好的保护,避免破损。阐述了阶梯式鸡蛋降落装置的结构及工作原理,通过理论计算和有限元动态模拟分析了装置结构设计的合理性,通过多次鸡蛋收集试验验证了结构的可行性。
Abstract:In view of problems of dirty and messy manual egg harvesting environment, high intensity, low efficiency and high cost, as well as existing egg landing device on market needs to eliminate original chicken cage, increase input cost, and has complicated structure, large footprint, etc., a stepped egg landing device was designed. This device has a simple structure, reasonable design, and could provide better protection for eggs to avoid damage when cooperating with egg collector for egg harvesting operations. Structure and working principle of self-developed stepped egg landing device were expounded. Rationality of structural design of this device was analyzed through theoretical calculate and finite element dynamic simulation. Feasibility of structure was verified through multiple egg collection tests.
