Description

Technical Field

[0001] The utility model relates to the technical field of garbage disposal, in particular to an organic wet garbage sorting and crushing integrated machine. Background Art

[0002] A large amount of wet garbage is generated during the classification of domestic waste, and the weight of wet garbage can account for more than 40-60% of the total weight of garbage. Wet garbage is perishable garbage, which refers to perishable biomass domestic waste such as food waste, leftovers, melon peels and fruit cores, and Chinese medicine residues. In addition to perishable components, wet garbage also contains certain biodegradable components such as cellulose, hemicellulose and lignin. Some large cities at home and abroad have explored how to convert food waste into usable resources. Before this, wet garbage needs to be sorted out from other garbage in advance to avoid secondary pollution caused by the decay of wet garbage.

[0003] The existing patent with application number 202111310196.0, "An automatic sorting and crushing machine for organic wet garbage", is a patent applied for by the applicant first, which discloses "by installing a grinding part in the inlet pipe, the feeding section of the grinding part pushes the garbage into the grinding section, and the grinding section crushes the wet garbage. After the wet garbage is crushed, it falls into the screening pipe, and a screening mechanism is installed at the lower end of the screening pipe. The screening threaded rod throws the garbage onto the screening mechanism, and the screening mechanism screens out the wet garbage and discharges the ground wet garbage from the first discharge port. The screening threaded rod transports the wet garbage that cannot be ground to the tail end of the screening pipe and discharges it from the second discharge port." Among them, the crushing, screening and sorting of wet garbage are achieved by the separate actions of the grinding part, the screening screw rod and the vibrating screening net. During the subsequent research and development process, the applicant believes that the structure of this all-in-one machine is relatively complex and the maintenance cost of the machine is high. Further, an organic wet garbage sorting and crushing all-in-one machine is proposed, which concentrates the crushing, screening and sorting in one chassis to simplify the structure and reduce maintenance costs.
