针对土壤灭火优势和其装置欠缺的问题,提出了手持式土壤灭火机设计构想。借鉴便携式植树挖坑机和立式螺旋输送机的结构及工作原理,从功能原理方案、结构、性能参数等方面对该机器进行了设计,最后根据设计结果进行了样机制作。经试验证明,该机器在土壤肥厚的森林和草原地域具有较好的灭火效果,并且操作方便灵活。 In view of the advantages of soil fire extinguishing and the lack of devices, a design concept of hand-held soil fire extinguisher is proposed. Draw lessons from the structure and working principle of portable tree planting machine and vertical screw conveyor, design the machine from the aspects of functional principle, structure, performance parameters and so on, and finally make the prototype according to the design results. The test proved that the machine has better fire extinguishing effect in the soil with thick forest and grassland area, and the operation is convenient and flexible.
