AI Technical Summary
In existing technologies, the crop stubble and soil are not thoroughly crushed, which means that the stubble burning mechanism cannot completely kill the disease and insect eggs in the soil, thus affecting the sterilization effect.
A pre-crushing mechanism, including a crushing frame, a rotating shaft, auger blades, and crushing blades, is set between the soil screening mechanism and the lifting mechanism to pre-crush the root stubble and soil clods, ensuring that they are fully crushed before entering the crushing mechanism.
The pre-crushing mechanism ensures that the stubble and soil clods are fully crushed, improving the sterilization effect of the stubble combustion mechanism and ensuring that pests and eggs are completely killed by high temperature.
