The Design And Experimental Research Of Disk Machine For Rice Bowl

Rice is the largest acreage in our country. Rice is the highest, most of the total productionof food crops. Rice is the Chinese largest food crop, also has a pivotal role in Chinese grainproduction in rice production, the disk shovel is an important part. Since existing methods stillrely on human, we use the artificial disk shovel, possess, other shortcomings with largeamount of labor, intensity and high personnel costs.The integrity of rice seedling greenhousespot disk shovel direct impact on a follow-up from late planting. Therefore, research and designa kind of rice in seedling growing tray disk machine has important significance. The maincontents of this study.This study follows the principles of machinery equipment design in domestic and foreignsoil cutting. As a systematic analysis in travel agencies and other related work conducted.Mainly designed and experimental research and analysis calculated the cut from the diskshovel in soil components.In this study, Heilongjiang Bayi Agricultural University has independently developed therice plant pot seedling disk shovel as the material. According to rice pot sterile factoryseedlings and the characteristics of seedling raising. We use a combination of theoreticalanalysis and experimental study. We designed a disk shovel in greenhouses of rice seedlingraising. Through the analysis of the structural parameters and operating parameters of the keycomponents of equipment from the disk shovels, explores the influence law these parameterson the integrity of the Seedling tray(1) In this study, analyzes and studies the key design principles set speed instruments,analyzed the against resistance from the disk shovel of soil. And preliminary design thecombined with agronomic requirements theoretically critical components from the disk shovel.Intended to the shovel body of the structural parameters, and the use of finite element analysissoftware were shovel body strength check.(2) In this study, parameters were optimized in operating parameters from the disk shoveldrive running gear and the main structural, and the machine has been installed trial. Analyzedthe effects of machinery shovel body in half-width horizontal edge clip,shovel blade tilt and the equipment traveling speed v in seedling tray for integrity. And study the effect inthree factors pot disk integrity experimental in conducted univariate. Intended to determine theranges of various factors.(3) In this study, we got the range of factors through the single factor experiment. Makesure test program in the take three factors determine. And got the factors affecting the testindicators, using SPSS software for the sub-factors. Use the Stepwise regression to get thelevels shovel blade clamp. Shovel blade angle body, equipment traveling speedv andthe regression equation in seedling tray full degree.Use optimization software for optimization solving to the regression equation. Get thethree factor optimization in optimal parameter combination of the levels shovel blade clamp. Shovel blade angle body, equipment traveling speed v. For the test in optimalcombination of parameters validated, make sure the operating parameters and structuralparameters determined by the combination of optimized to meet the design requirements, Torealize the mechanization of rice seedling disk, to reduce the labor intensity, reduce theamount of labor, to improve the working efficiency.
