Description

Technical Field

[0001] The utility model relates to the technical field of fruit and vegetable garbage treatment, and more specifically, to a garbage crusher which can completely crush fruit and vegetable garbage. Background Art

[0002] Fruit and vegetable waste refers to the waste generated in residents' daily lives and food processing activities, including discarded vegetable leaves, leftover rice, fruit peels, eggshells, tea dregs, etc. Its main sources are home kitchens, restaurants, hotels, canteens, vegetable markets, fruit markets, supermarkets and other industries related to fruit and vegetable trading and food processing.

[0003] The prior art application number is CN202223498652.1, which discloses a new type of kitchen waste crusher, including a base, a vertical tube fixedly installed on the upper surface of the base, an inclined plate fixedly installed inside the vertical tube, a horizontal tube connected to one side of the vertical tube, a sealing box fixedly installed on the upper surface of the base, a motor fixedly installed on one side of the inner wall of the sealing box, a rotating rod fixedly installed on the output shaft of the motor, one end of the rotating rod passes through the vertical tube and extends to the inside of the vertical tube, and crushing knives are fixedly installed on both sides of the rotating rod; the utility model drives the crushing knives on the rotating rod to rotate by the motor, so that the crushing knives perform a crushing operation on it.

[0004] However, the above solution still has the following drawbacks: during the use, the kitchen waste is crushed, and the garbage fragments that are initially crushed fall quickly, and there is almost no chance of re-crushing the garbage fragments unless the garbage fragments are fed back in. Therefore, the efficiency is low and the crushing is incomplete. Utility Model Content
