Referring to fig. 1 to 3, an embodiment of the present invention provides a crushing apparatus 100, and the crushing apparatus 100 can be used for crushing food waste. Optionally, the food waste in this embodiment is food waste in a household kitchen. The food waste comprises soft waste and hard waste.

Referring to fig. 4 to 7, the crushing apparatus includes: a housing structure 10, a cutter structure 20 and a drive structure 30. The housing structure 10 is embodied with a crushing chamber 111 for food waste. After the food waste is thrown into the crushing cavity 111, water with a proper proportion can be added into the crushing cavity 111 according to requirements, so that the food waste has certain fluidity in the crushing process. The cutter structure 20 is provided in the crushing chamber 111 and serves to crush the food-trash in a rotated state. The cutter structure 20 comprises a rotating shaft 24 with one end rotatably connected to the bottom of the crushing cavity 111, a first cutter 21 connected to the rotating shaft 24 for cutting food waste, and a second cutter 22 connected to the rotating shaft 24 for blunt-cutting food waste, and a driving structure 30 connected to the housing structure 10 for driving the rotating shaft 24 to rotate. The thickness of the cutting edge of the first knife 21 is less than that of the second knife 22, that is, the sharpness of the first knife 21 is greater than that of the second knife 22, so that the area of the cutting edge of the second knife 22 contacting with the food waste is larger than that of the first knife 21, and the second knife 22 generates a larger cutting force, that is, a blunt effect, on the food waste, so that a larger cutting force can be generated on the waste with higher hardness, such as bone, in the food waste, and the waste is split into a plurality of small bodies with equal or less volume, so that the massive hard food waste is efficiently granulated, and the first knife 21 is also beneficial to cutting. Because the cutting edge of first cutter 21 is sharper than the cutting edge of second cutter 22, when handling soft waste and light rubbish, can realize the cutting of making good use of fast of soft waste and light rubbish, for example when handling zongzi leaf and vegetables, the cutting edge of first cutter 21 can make good use of cutting with zongzi leaf and vegetables fast to make zongzi leaf and vegetables refine, avoid causing blowdown pressure and jam to sewage pipes. It can be understood that, in the actual processing process, the first cutter 21 and the second cutter 22 are combined and form complex mixed cutting, that is, the first cutter 21 also cuts, gradually grinds and cuts the hard garbage, and slowly cuts the overall size of the hard garbage to be smaller; of course, during the process of processing the hard garbage by the first cutter 21, scratches or micro cracks may be formed on the surface of the hard garbage, which may damage the hardness of the hard garbage, and also facilitate the blunt cutting of the second cutter 22, i.e., forming a complicated hybrid cutting process. Thereby sufficiently crushing the food-trash. The cutter structure 20 cuts the food-trash into fine granular residues, and then the food-trash is discharged or dumped from the crushing chamber 111 to a dumping terminal, such as a sink, thereby completing fine granulation dumping of the food-trash and preventing clogging of a sewer line.

Since the edge thickness of the second cutter 22 is greater than the edge thickness of the first cutter 21, the sharpness of the first cutter 21 is greater than the sharpness of the second cutter 22. That is, the first cutter 21 has a sharp cutting characteristic, and the second cutter 22 has a blunt cutting characteristic. By providing a first cutter 21 for sharp cutting and a second cutter 22 for blunt cutting on the rotary shaft 24. Compared with the second cutter 22, the first cutter 21 has a relatively sharp feature, the first cutter 21 is generally in a blade style, and the first cutter 21 is suitable for cutting coarse fiber garbage, soft garbage and light garbage, such as rice dumpling leaves, egg shells and the like. It will be appreciated that the first cutter 21 also has a predetermined thickness dimension to ensure structural strength and to prevent curling or chipping when cutting hard food waste such as bone. The second tool 22 is relatively less sharp than the first tool 21 and is typically a bluntly disposed raised bump. In particular, during operation, the second tool 22 has a better hammering effect, i.e. blunt cutting, while the first tool 21 has a better cutting effect, i.e. the second tool 22 is more suitable for hammering large bones; the first cutter 21 can cut the bone which is hammered into small particles, so that the cutting effect is better. Therefore, the ingredients with higher hardness in the food waste are firstly subjected to blunt cutting by the second cutter 22, are crushed by preliminary blunt impact, and are further cut by the first cutter 21, so that the food waste is completely cut into fine particles and is fully crushed, and further the blockage of a sewer pipeline is avoided.

Referring to fig. 8 to 9, in an embodiment, the first cutter 21 is disposed in a sheet shape, and the second cutters 22 are disposed on the cutter surface of the first cutter 21 at intervals, so that the cutter structure 20 has a hybrid crushing and cutting function.
