The driving motor 7 can drive the rotating shaft 10 to rotate together with the various sleeve flanges 11. When the sleeve flange 11 rotates, the first cutter head assembly and the second cutter head assembly can be driven to rotate together. At this time, the first cutter head assembly and the second cutter head assembly can be used to crush the food waste in the bin body 4, so as to reduce the volume of the food waste, thereby reducing subsequent transportation costs.

When the shaft sleeve flange 11 rotates, it can drive the first cutter head assembly and the second cutter head assembly to rotate together. At this time, the food waste in the bin body 4 can be crushed by the first cutter head assembly and the second cutter head assembly, so as to reduce the volume of the food waste, thereby reducing the subsequent transportation cost. Compared with the existing double-shaft double-roller crusher, the single-shaft transmission greatly reduces the rapid wear caused by the double-roller crushing roller, thereby reducing the replacement cost, and by controlling the forward and reverse rotation of the motor 7, the crushing mechanism can be driven to rotate forward and reverse to achieve loose materials and two-way crushing effect, thereby effectively improving the crushing energy.
