Description

Technical Field

[0001] The utility model belongs to the technical field of gardening garbage treatment and resource utilization, in particular to a gardening garbage treatment system. Background Art

[0002] Due to the large-scale landscaping in cities, large and medium-sized cities, especially southern cities with a warmer climate, generate a huge amount of landscaping waste, second only to domestic waste. Landscaping waste is relatively fluffy, and takes up a lot of space for transportation and storage. The collection, transfer and centralized large-scale processing and transportation costs are high. Therefore, the treatment of landscaping waste has become one of the problems faced by urban gardening and sanitation departments.

[0003] Garden and greening waste is rich in organic matter and nutrients such as nitrogen, phosphorus and potassium. If it is crushed, piled and fermented nearby at the source, it will be an ideal garden and greening matrix. It can be recycled and reused in urban garden and greening planting and residents' courtyard, balcony flower and vegetable planting. It can not only reduce garbage stacking and significantly improve the environment, but also greatly reduce energy consumption and carbon emissions caused by long-distance transportation, which is very beneficial to promoting the construction of waste-free cities and green and low-carbon cities.

[0004] However, there is still no integrated system equipment on the market that can meet the needs of urban garden and greening waste crushing and resource utilization. Common wood slicers, straw shredders, shredders, hammer crushers, etc., these devices either mainly process some thicker branches, or mainly process some small and long branches and leaves. They are unable to uniformly process common urban mixed garden and greening waste, and they all generate too much noise and dust during operation, which makes it difficult to meet the city's noise and dust pollution control requirements. Therefore, the garden and greening waste generated in cities is basically piled up for a long time, and after accumulating to a considerable amount, they are transported to outside the city for disposal or incineration.

[0005] Therefore, it is necessary and valuable to develop an integrated crushing system that can meet the needs of urban mixed landscaping waste crushing and composting resource utilization, as well as the requirements of urban noise and dust control. Summary of the invention
