Research Of Cutting And Collecting Device System Of The Aquatic Plants On The Surface Of The Water

In recent years, with the growing problem of eutrophication, plantpollutants frequent large-scale outbreak. The outbreak of plant pollutantsand the salvage and cleanup work of other waste has become a nationalproblem. The main purpose of the research and applications of cutting andcollection device systems of aquatic plants is to improve efficiency, and toreduce labor intensity. The main purpose and mission of the Plants cuttingand collection device is: to achieve mechanical salvage of plant pollutants,to simplify the whole system, to achieve flexible and convenient operation,and to reduce the cost of equipments.According to the main purposes of cutting and collection devicesystems of aquatic plants and the analysis of traditional manual cuttingand salvage of aquatic plants and river grass trimmers, a new type ofcutting and salvage device has been introduced. The peeling cutter andscrew conveyor has been used in this new salvage device. The size, speedand other parameters of the device’s main working parts have beendiscussed and analysed as well; and the twining problem of the screwconveyor salvage device has been researched and the optimizationalsolution has been proposed as well. Furthermore, an Analysis softwareANSYS has been used to do mechanical analysis and modal analysis onthe hob in order to provide support for hob optimization. The maincontents are: Introduction; the solution of designing plants collectiondevice; research of salvage device design; research of cutting devicedesign; hob Modal Analysis; Summary and future respectively.The design of Plants salvage and collection device. Based on theoperating characteristics analysis of the reciprocating harvesters and rollrake salvage devices, the solution of design of cutter and delivery devices have been identified. Using peeling cutting and screw delivery process, thedevices can cut plant pollutants peelingly and suck the pollutants into thecabin through the screw conveyor. At the same time the devices play therole of initially filtering water. The main purpose of design solution is tostrive to achieve several requirements such as efficient operations, a wideharvest, simple transmission, smooth working and high productivityrespectively.The design of salvage device. Determine the form of a screwconveyor salvage plant pollutants, simple structure, stable operation,moreover the devices can cut plant pollutants peelingly and suck thepollutants into the cabin through the screw conveyor while the devices areplaying the role of initially filtering water. As the actual productionrequirements of Jiangsu Liyang a shrimp and crab farms as a reference todetermine the parameters of the helical blade diameter and limiting speedand so on. In order to overcome the twisting problem of salvage processplant pollutants and garbage wrapped, to optimize the design of salvageequipments in order to improve the performance of anti-twisting.The design of cutting device. Sure the peeling hob cutter cutting plantpollutants, simple transmission, either wide harvest, the new high-speedand high-speed operation cutters. Aspects of the arrangement starting fromthe hob cutting the force, hob blade, the Hob blade edge tooth helix angle,hob blade materials analysis.The modal analysis of cutter. In this study, the actual production ofJiangsu Liyang a shrimp and crab farms, combined with the aboveanalysis to determine the hob prototype. The cutter using SolidWorkssoftware to create three-dimensional model, the use of finite elementanalysis software ANSYS to compare the CFX pressure and static pressureof different speed cutter affects. The speed of500rev/min cutter andmodal analysis, come to cutter vibration performance.Finally, the full text of the summary and outlook. The design ofplants cutter and salvage device, and to do a more in-depth research, madesome progress, but at the same time, some research work also worth further expand, specifically consider the following aspects:(1) Integrated cutting fishing gear. Peeled hob is mounted on theinner wall of the shovel-shaped inlet of the screw conveyor device, i.e. theintegrated cutting salvage device, the harvesting the salvage deviceintegrated, watergrass a by cutting is conveyed directly to the cabin.Comparing the difference between integrated harvesting fishing gear in thethe plants drain cut rate and leakage yield on the difference with this studyunit, in order to adapt to different job requirements(2) To improve machine stability. The study compared cutter andsalvage device installed in a monohull and catamaran stability, so that thewhole stable operating environment of large waves.(3) Reduce the hob lateral force. Further research comparing differentangle and hob helix angle blade arrangement, hob lateral forces, improvethe service life of the cutter.(4) To carry out field experiments. Test the machine operation;compare different cutter speed and salvage of the fishing gear speedoperational efficiency, to improve the efficiency of the unit.
