Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, specifically a combined orchard branch shredder. Background Technology

[0002] With the implementation of air pollution control and environmental policies, methods such as piling and burning or centralized dumping of tree branches in orchards in my country have been gradually prohibited. On-site shredding and returning the branches to the field using a shredder has become the most common method. This not only saves labor costs but also improves soil organic matter fertility, achieving the ecological recycling of orchard organic waste resources. As a key piece of machinery for the full mechanization of orchard operations, the branch shredder plays a vital role in the resource utilization of tree branches and ecological environmental protection.

[0003] Currently available orchard branch shredders operate in a single mode, typically using a combination of moving and fixed blades. This results in a large, non-adjustable particle size, limiting their application to soil remediation. If orchard branches are pruned and shredded twice a year, the material cannot decompose and rot in time, failing to achieve the goal of "using trees to nourish trees" and instead increasing the burden on the soil. Furthermore, the large and uncontrollable particle size makes it difficult to utilize the excess wood chips for other purposes. Additionally, there are shredders combining swivel blades and screens, which, while allowing for particle size control, suffer from high power consumption and low efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a combined orchard branch shredder, which achieves fine shredding of branches through a combination of primary chopping and secondary shredding. It can control the particle size and improve shredding efficiency. The shredded wood chips of different particle sizes can be returned to the field or used for other purposes.

By changing the screening plate 213 with different apertures, different crushing particle sizes can be obtained, thus realizing secondary crushing.

[0037] Finally, it should be noted that the above description is merely an embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
