Design and experiment of small scale biogas slurry fertilizer applicator
Because the biogas slurry on the surface would have caused a lot of volatilization of substances,it is difficult for organic components to be deeply absorbed and utilized by plants,resulting in environmental pollution and resource waste.In order to make full use of biomass resources,this paper designed a small semi-hanging biogas slurry fertilizer application machine based on reference to domestic and foreign underground irrigation of separate,integrated,self-propelled and pipe-conveyed types,and analyzed the key components such as methane tank,frame and deep-loose type fertilizer plow,used SolidWorks to conduct three-dimensional modeling for the machine,and used simulation analysis module to analyze the stress of key mechanism components,to determine the structure of the prototype machine,and carry out the prototype production.Field experiments showed that when the regulating valve was adjusted to the maximum and the machine was operated at the speed of 1.5 m/s,the raw materials in the tank were emptied within 5-6 min,and the thickness of the wet soil was 7.3-15.6 cm,which achieved the purpose of continuous fertilization by the machine.
