| China is a major country of mussel farming.At present,research on increasing income and processing of mussel farming is increasing year by year.Mussel seedling rope equipment is an indispensable part of it,and equipment development also needs to keep up.In the field of mussel breeding,the application research of mussel seedling rope equipment mainly focuses on the use of chemical fiber materials and specific device spinning forming technology,but traditional seedling rope breeding has a certain impact on the environment and the quality of mussels,such as vision and smell.Environmental pollution issues,etc.According to the current development needs of green mussel farming,this article proposes to propose the research of green mussel seedling rope material forming technology.The research content mainly focuses on the research of green mussel seedling rope material and the design of rope making equipment.The content was expanded,and related verifications were carried out through material selection and series of experiments.Among them,the most economical rice straw material was selected as the green material,and the rope making equipment and seedling rope equipment were formed and prepared as the follow-up green seedling rope.Forming research and application provide a reference basis.The main tasks of the thesis are as follows:Materials of mussel seedling rope:(1)The material selection of green mussel seedling rope was determined.Comparing with the current mussel seedling rope devices at home and abroad,a green material was proposed to be used as mussel seedling rope.The current utilization,yield and economy of the primary green materials(hemp,brown and rice straw)were compared and analyzed,and the rice straw with the best economy was selected as the green seedling rope material to be studied.(2)Standard Determination of tensile strength of straw rope materials.Through the ANSYS finite element simulation analysis experiment of the straw rope model and the prototype solid tension experiment,it is concluded that under the simulation conditions,the rope can meet the stress,strain,safety factor and total deformation stress requirements,and under the actual tension experimental conditions,the ultimate peak tension,deformation displacement and elongation of the rope meet the required requirements,which provides the tension support for the subsequent mussel seedling rope sea crane experiment Parameter range.(3)Experimental analysis of chemical reaction of rice straw enzymatic hydrolysis.Through the experimental observation,under the condition of enzymatic hydrolysis,protease and nutrient elements were released from the straw rope material to supply the growth of mussels.Under the seawater immersion corrosion,the matrix structure such as cellulose and lignin had the characteristics of periodic slow degradation and autolysis,which met the demand and provided the basis for the follow-up sea crane experiment.(4)Experimental verification of mussel seedling rope and grass rope equipped with sea crane.Under the actual sea crane conditions,the effects of seawater p H,water wave,wind,weather and other data on the failure test of grass rope were observed,and the results showed that the grass rope could meet the comprehensive performance of the sea crane;compared with the influence of the corrosion of grass rope and chemical rope net on the environment,the grass rope was more environment-friendly,which provided a further research on the design of mussel seedling rope equipment and rope making equipment for the application of grass rope materials This paper provides a theoretical support.The rope making equipment of mussel seedling rope and grass rope:(5)Overall device and related parts design.In this paper,the equipment and technology of mussel rope making in China were summarized.Referring to the equipment and technology of several quasi experimental research(absorbable,degradable,non-staple food),the whole equipment and parts structure were designed by using Solid Works.(6)The simulation analysis of key parts of equipment is carried out by ANSYS finite element software.The stress reliability of the components is determined by observing the cloud diagram of equivalent total deformation,equivalent strain and equal effect force.(7)In the electric control design part of the device,sensors and timers are selected to control the whole system scheme(clamping,binding and shearing processes).Keil software is used for programming and Proteus Software is used for synchronous simulation,which provides an important theoretical basis for the forming of the rope making machine prototype. |
