Description

Technical Field

[0001] The utility model relates to the technical field of green waste disposal, in particular to a green waste pretreatment device. Background Art

[0002] Green waste mainly includes tree, shrub, and flower pruning waste generated during the construction, management, and maintenance of landscaping, as well as plant residues produced by natural plant withering. These wastes have good renewable properties and diverse utilization methods. Resource utilization can reduce environmental pollution and create economic value at the same time. To promote the resource-based recycling of landscaping waste, waste branches, leaves, and grass clippings are crushed and composted, and then backfilled under trees and in green spaces, which not only prevents dust and soil erosion but also increases soil organic matter, boosting the green and low-carbon development of landscaping waste classification and treatment.

[0003] The working principle of a green waste crusher is to cut, crush, and screen tree trunks and branches through the coordinated action of a crushing mechanism and a screening mechanism, thereby achieving a crushing effect. After the branches enter the crusher, they are driven by the main drive motor and enter the crushing mechanism for crushing, and then enter the screening mechanism for grading. Finally, particles of different sizes are separated to achieve the desired crushing effect. However, most existing green waste crushing devices rely on manual feeding and cannot initially screen the waste. Sand and gravel contained in green waste are easily mixed into the crushing unit, wearing the blades; most green waste crushing devices cannot meet the crushing requirements for both thick tree trunks and thin branches at the same time; in addition, a large amount of dust is generated after wood is crushed, resulting in a poor on-site working environment. Most existing crushing devices use dust reduction measures during the crushing process, ignoring the dust removal requirements at the discharge port. Summary of the Invention
