Development And Failureanalysis On Motorized Soil For Agriculture

In order to facilitate access to soil samples in agricultural research, thearticle is the design and research of the direct-pressure powered sampler and gasolineengine type sampler. It discusses the working theory and structural characteristicsabout the two motor samplers, And details the selection work of the gasoline enginepower and so on. Through the mechanical analysis of sampler under impact load,analyze and improve the structure of such as tube boots which easily failed to improvethe work life of the soil sampler. Through design and tests steadily, determine theoptimum structure parameters of samplers.The results of analysis about questions occurred in operating process about fieldwork show that:1. Direct-pressure electric samplers have advantages such as easy operation andrapid drill. But its biggest drawback is the inconvenience of power Gets in field, justwith increase of tedious labor.2. Through experiment,"bi-convex" structure is not suitable for direct-pressureagricultural sampler because of such as blocking matters due to air pressure and otherissues.3. Gasoline engine type samplers remove the problem of power obtained noteasily, have a larger advantage both in terms of operation and portability. Adoptingbevel gear transmission ensures samplers with smooth, compact soil workcharacteristics.4. After verification, it plays a prominent role in extending the working life aboutsampler tube boots and impact seats though such as methods of changing undercutsinto load reducing slot with rounded forms, to ensure the efficiency of sampler.
