Fig. 2 shows a schematic partial structure of the garbage pretreatment apparatus 10. The garbage pretreatment apparatus 10 includes a hopper 101, a wringer portion 102, and a scraper portion 103. The feed hopper 101 guides the material to the wringing portion 102, the scraping portion 103 is provided in the feed hopper 101, and the scraping portion 103 scrapes the material to the wringing portion 102.

The garbage pretreatment device 10 mainly minces garbage, and the hopper 101 is formed with two openings, the material twisting part 102 is disposed at the opening below the hopper 101, and the other opening is used for adding material into the hopper 101. The material is guided to the wringing portion 102 by the feed hopper 101, while the feed hopper 101 has a function of temporarily storing the material to be minced. The wringing portion 102 is an execution component of the garbage pretreatment device 10, and the material is minced by the operation of the wringing portion 102, thereby achieving the effect of pretreatment of the material.

In this embodiment, the feeding hopper 101 is in a trapezoidal hopper shape, that is, the outlet of the feeding hopper 101 converges relative to the inlet, and the inlet opening of the feeding hopper 101 is larger, so that the feeding of materials is facilitated. The material twisting part 102 is arranged at the small end of the feed hopper 101, and the small end of the feed hopper 101 corresponds to the size of the material twisting part 102, so that materials conveyed by the feed hopper 101 all flow to the material twisting part 102 to achieve the effect that the material twisting part 102 sufficiently pulverizes the materials. The scraping part 103 is arranged on the side wall of the feed hopper 101. Specifically, a side wall of the feed hopper 101 is provided with a groove, a scraping hopper is connected, and a part of the scraping part 103 is embedded into the scraping hopper and extends into the feed hopper 101, so that the scraping part 103 does not obstruct the falling of materials, and can stir the materials timely, so that the materials and the twisting part 102 are prevented from forming a hollow area, and the feeding blockage is formed.

In this embodiment, the material twisting portion 102 includes two material twisting rollers 1021 distributed side by side, material twisting teeth are disposed on the material twisting rollers 1021, the material twisting teeth of the two material twisting rollers 1021 are meshed with each other, and a gap exists between the material twisting teeth.

In this embodiment, the scraping portion 103 includes a rotary cutter shaft 1031 and a rotary cutter 1032 disposed on the rotary cutter shaft 1031. The rotary knife 1032 is adopted to scrape the material to be minced to the material-twisting roller 1021, so that the structure is simple, and the falling of the material is not easy to be blocked.

The scraping portion 103 is disposed obliquely above the wringing portion 102, and the rotation tangential direction of the side of the rotary blade 1032 opposite to the wringing portion 102 faces the wringing portion 102. The tangential line of rotation of the rotary knife 1032 faces the material twisting part 102, the scraping direction is stronger, and the gap formed between the material twisting part 102 and the feeding hopper 101 is more favorable for breaking the material.

The garbage disposal system 1 of the present application has the following advantages:

1. the garbage dewatering device 20 comprises an adjustable elastic extrusion mechanism 203, and the elasticity of the elastic part 2032 can be adjusted through the adjustable elastic extrusion mechanism 203, so that the extrusion force of materials is adjusted, namely the dewatering degree of the materials is adjusted, the water content of garbage treatment can be accurately controlled, and the kitchen garbage dewatering device can adapt to different dewatering requirements of kitchen garbage with complex components and different regional components.

2. The garbage dewatering device 20 adopts a spiral conveying shaft, the diameter of a spiral blade 2021 on the conveying direction of the spiral conveying shaft is changed, in the process of conveying materials, the conveying space is reduced, an extrusion effect is formed on the materials, the effect of conveying and dewatering is achieved, and the dewatering effect is further optimized.

3. The garbage pretreatment device 10 is provided with the scraping part 103 in the feed hopper 101, continuously stirs the materials on the stranding part 102, breaks the hollow area formed between the loose materials and the stranding part 102, effectively prevents the blockage caused by accumulation on the stranding part 102 of the excessive materials, and ensures that stranding of the stranding part 102 is smoother and ordered.

4. The garbage treatment system 1 integrates functions of garbage mincing and garbage dewatering, and can complete mincing and dewatering treatment of materials by only feeding the materials at the feeding hopper 101 and collecting the treated materials at the discharging hole 2011, so that the garbage treatment system is high in functional integration level, convenient to operate and high in quality and efficiency.
