In the prior art, no better treatment mode exists for kitchen waste (especially kitchen waste in large and medium-sized catering places), the most common treatment mode is mixing common household waste for mixed treatment, so that the treatment pressure and various investment cost of a landfill site and a sewage treatment plant are increased, and secondary pollution is unavoidable. Meanwhile, the kitchen waste is required to be collected uniformly in the treatment mode, and is conveyed to a kitchen treatment plant for separation, pulping, desanding and heating oil extraction treatment, and as light sundries and heavy sundries in the waste are difficult to separate, several stages of separation and desanding are often required, the process technology is complex and complicated, the equipment is high in stable operation difficulty, and the investment and operation cost is high.

When the cutterhead rotor 110 which is arranged in the accommodating space 150 and rotatably arranged on the stator screen 140 rotates, kitchen waste in the accommodating space 150 can be well pulped. The pulped slurry is discharged from the stator screen tray 140 to a preset place to wait for further treatment, so that the kitchen waste can be rapidly pulped, and the kitchen waste can be treated more conveniently (without sorting and desanding several times). Meanwhile, the rotor swing arm 120 on the cutter rotor 110 can adjust the granularity and the efficiency of slurrying by adopting different working rotating speeds through the cutter rotor 110. Further, the granularity of the kitchen waste after pulping can be adjusted by adjusting the distance between the adjacent tooth-shaped columns, and the kitchen waste can be rapidly crushed and pulped to below 10mm in granularity, so that the convenience for processing the kitchen waste is remarkably improved. The executing device 10 has the advantages of simple structure, convenient operation, capability of obviously improving the efficiency of kitchen waste crushing and pulping, convenient manufacture and contribution to large-scale flow line production.

Optionally, the vane 112 and the rotor swing arm 120 are both obliquely disposed on the cutterhead rotor 110; and the inclination of blades 112 and rotor swing arms 120 is the same. The inclined blades 112 and the rotor swing arms 120 can strengthen the effect of breaking and pulping kitchen waste, and the blades 112 and the rotor swing arms 120 are obliquely arranged to cooperatively strengthen the work of the execution device 10.
