摘要/Abstract

摘要： 由于沼液沼渣地表撒施会造成大量物质挥发，导致有机成分很难被植物深入吸收利用，造成环境污染和资源浪费。为充分利用生物质资源，在参考国内外分开式、一体式、自走式、管道输送式等地下施灌的基础上，设计小型半挂式沼液沼渣施肥机，对沼液罐、机架、深松型施肥犁等关键部件进行分析，运用SolidWorks对该机进行三维建模，利用仿真分析模块对关键机构部件进行应力分析，确定样机结构，并进行样机制作。田间试验表明：当调节阀调到最大，机具以1.5 m/s的速度前进作业时，罐内原料在5~6 min内排完，渗湿土壤厚度在7.3~15.6 cm之间，实现连续施肥。

Abstract: 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.
