Description

Technical Field

[0001] The utility model belongs to the technical field of fallen leaf recovery, and in particular relates to a fallen leaf recovery and centralized compression device. Background Art

[0002] The leaf recycling and centralized compression device is a mechanical device specially designed for collecting and compressing fallen leaves. Its main purpose is to effectively reduce the space occupied by fallen leaves, significantly improve the efficiency of the entire process from collection to transportation of fallen leaves, and significantly reduce processing costs. With the continuous improvement of urban greening levels, the large amount of fallen leaves produced every autumn poses a considerable challenge to urban management and environmental protection. Traditional methods of leaf disposal often require a lot of time and manpower, and due to the large size of fallen leaves, they also take up more space resources during transportation, resulting in increased costs. In order to solve these problems, the leaf recycling and centralized compression device came into being.

[0003] Existing leaf compression devices do face a common technical challenge when performing leaf compression tasks: due to the limited compression space and structural design limitations, when the leaves are compressed to a certain extent, they often form a tight fit with the compression chamber wall. This close contact not only increases the difficulty of removing the leaves from the compression chamber, but also may cause the equipment to jam during operation due to the increased friction between the leaves and the chamber wall, and even cause wear or damage to mechanical components. In the long run, this not only seriously affects the overall efficiency of leaf processing, but also shortens the service life of the equipment, increases maintenance costs, and is inconvenient to use. Therefore, we propose a leaf recovery and centralized compression device with easy-to-use functions, which is urgently needed to be developed. Utility Model Content

[0004] The present invention aims to provide a centralized leaf collection and compression device to address the technical issues raised in the prior art regarding the limited space and design limitations of existing leaf compression devices, which often cause the leaves to adhere tightly to the walls of the compression chamber when compressing the leaves. This not only increases the difficulty of leaf removal, but can also cause equipment jamming and wear, reducing work efficiency, shortening equipment life, increasing maintenance costs, and affecting ease of use.
