Design And Study Of Large Scale Hydraulic Drive Reel Sprinkler Irrigation Machine And Its Control System

As an efficient water-saving irrigation equipment,reel sprinkler irrigation machine has the advantages of homogeneous irrigation,water saving,flexible use,strong adaptation and manpower saving,which is widely used all over the world.However,with the continuous expansion of agricultural production scale,modern agriculture is gradually developing towards mechanization,informatization and intelligentialize.And as one of the widely used agricultural infrastructure equipment,traditional reel sprinkler irrigation machine has the disadvantages of high energy consumption,low efficiency,low degree of automation and low control accuracy,which have seriously restricted the development of modern agriculture.Besides,with the implementation of land transfer and other policies,farmland is expanding continuously and the working efficiency of the reel sprinkler irrigation machine of small and medium sizes has been difficult to adapt to the current situation.In order to solve the above problems,this paper is mainly aimed at the design of large scale hydraulic drive reel sprinkler irrigation machine and its control system.At present,the reel sprinkler irrigation machine of small or medium size is domestic widely used and water turbine or electromotor is always used as the power source of the system.The research results of this paper are of great significance to the future research of the reel sprinkler irrigation machine,especially the large scale hydraulic drive reel sprinkler irrigation machine.This paper aims to realize the large flow rate automatic sprinkler irrigation,which studies and designs the large scale hydraulic drive reel sprinkler irrigation machine according to the general flow of product design.First of all,this paper completed the overall scheme design,determined the main design parameters and designed the drive system of the large scale hydraulic drive reel sprinkler irrigation machine.Secondly,this paper completed the detailed design of the important structures,established the three-dimensional model of the whole machine,used the ANSYS Workbench to analyze the main structures and designed the unsymmetry device.Then,this paper completed the hydraulic system design,the schematic design of hydraulic system and completed the design and selection of executive components,hydraulic pumps and diesel engines.Besides,this paper established the simulation model of load-sensitive variable pump and reel-driven hydraulic system with AMESim and carried out the simulated analysis.Finally,this paper completed the design of remote management and control terminal which is used to reel sprinkler irrigation machine,made the prototype and carried out the field test experiments.Moreover,this paper designed the field control system of the large scale hydraulic drive reel sprinkler irrigation machine,completed the schematic design,hardware selection and software design.The paper finally summarized the work,and the study of relevant technology is discussed as the future work.
