[0002] The moving cutter of the kitchen waste crusher on the market adopts a whole structure, and the cutter processing and maintenance cost is high, and the replacement is relatively complex. In view of this, the Chinese utility model patent with the authorization announcement number CN207769978U discloses a double-shaft shredder blade, which comprises a disc-shaped cutting cutter body (i.e. cutter head) and an annular cutting cutter plate attached to the two side surfaces of the cutter head. The cutter head is provided with a tooth-shaped feeding protrusion (i.e. feeding cutter head) around the periphery. The annular cutting cutter plate is surrounded by a plurality of cutting blades. The arc surface of the cutting blade is provided with a plurality of groove-shaped shear edges. The cutting blade is detachably connected with the cutter head.

[0003] In use, the cutter heads are arranged and combined at intervals along the axial direction on the transmission main shaft of the shredder. The cutter head drives the annular cutting cutter plate to rotate, and the shear edges of the cutting blade perform shredding operation. When the cutter is worn and needs to be replaced by individual shredder blades, only the individual worn cutting blades need to be removed, and new cutting blades are installed on the cutter head to replace the original worn cutting blades. In this way, the entire shredder blade does not need to be discarded, production materials are saved, and replacement is convenient.

[0004] Among them, the feeding cutter head integrally arranged on the cutter head in the circumferential direction plays a role in scraping the garbage into the space between the two transmission main shafts, so that the cutting blades arranged staggered on the two transmission main shafts can effectively cut the garbage. Since the feeding cutter head directly contacts with the garbage, there is a large wear after long-term use. When the cutter is replaced, the cutter head needs to be scrapped as a whole, which causes high maintenance cost of the cutter. In addition, the entire cutter needs to be removed from the transmission main shaft, and the cutting blades that can still be used need to be reinstalled on another cutter head, which causes complex replacement operation. SUMMARY

[0005] The purpose of the present application is to provide a kitchen waste crusher cutter to solve the problem of high maintenance cost and complex replacement operation caused by the need to scrap the entire cutter head when the feeding cutter head of the cutter in the prior art is worn.
