Flipped oscillator is a solid waste leaching toxicity leaching test equipment. During the stacking or disposal process of solid waste containing harmful substances, if it encounters water leaching, the harmful substances will migrate and transform, polluting the environment. Leaching experiment is a field or laboratory simulation of this natural process. When the amount of harmful substances leached exceeds the threshold set by relevant regulations, the waste has leaching toxicity. The identification of leaching toxicity of solid waste is the basis for determining hazardous waste and an important technical link in the development of solid waste management and disposal technology The structure of this testing machine has broken through the design ideas of existing domestic products,
