Design And Research On Liquid Straw Inoculant Variable Spray Machine

Spraying liquid straw lnoculant In the process of returning straw to the soil,can speed up the speed of straw decay,a significant reduction in farmland rest period,improved farmland utilization rate and straw return rate.Liquid straw lnoculant and water storage in the box of liquid straw inoculant variable spray machine,liquid straw inoculant variable spray machine requires uniform spraying and requires control of the flow rate to match the various tractor and straw returning machine working speeds.In this paper,making test analysis of liquid straw lnoculant density and viscosity,doing the theoretical calculation and design of liquid straw inoculant variable spray machine,simulation analysis of the variables influencing in liquid straw inoculant variable spray machine was carried out using simulation analysis.The main work is as follows:First of all,the current situation of straw returning to domestic and foreign research is compared,and determination the characteristics of liquid straw lnoculant.A new type of liquid straw lnoculant spraying device was designed.The method of variable spraying was analyzed.The main design parameters of the main equipment and systems,namely the spraying system,the material box and the rack are analyzed and calculated.Then,using the commercial software GAMBIT and FLUENT to do modeling and simulation of nozzle spray on the liquid detergent agent spray device spray.The influence factors of spraying effect and spraying height on the spraying effect of the nozzle are obtained,and the nozzle installation distance range of liquid straw inoculant variable spray machine is obtained.Finally,Taking the spray rate,spraying height and nozzle spacing as the three factors,taking the coefficient of variation as the reference index,three levels of three-level orthogonal test were established.Using the statistical software Minitab to analyze the orthogonal test and variance test data to get the best parameter setting,best parameter setting can be used to guide the spray flow rate,spray height and spray spacing parameter setting of the liquid straw inoculant variable spray machine.In the developed liquid straw inoculant variable spray machine on the field test,the experimental data obtained with the simulation analysis is basically the same,indicating that the simulation results are reliable.After the identification of agricultural machinery identification station in Hubei Province,the test results show that liquid straw inoculant variable spray machine meet the expected design requirements.In summary,the design of the liquid straw inoculant variable spray machine can be combined with farmland complex environment for liquid straw inoculant of the variable spraying and uniform spraying,achieving the purpose of straw back to field Efficient.the application of liquid straw inoculant and even straw technology to play a certain role in promoting.
