Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, and in particular to a transmission structure for lawnmowers that is easy to maintain. Background Technology

[0002] Existing lawnmowers typically use an engine that drives a cutter shaft via a transmission belt, which in turn drives the mowing blades to achieve the mowing function. However, traditional transmission structures usually place the belt outside the machine body, making it susceptible to external environmental factors. Especially since lawnmowers often operate in harsh environments, the belt is prone to wear and breakage. To address this issue, designs have emerged that integrate the belt, incorporating protective devices within the machine body to effectively prevent damage from external factors and extend its lifespan. However, while the integrated design improves belt durability, it also increases maintenance difficulty, requiring the disassembly of numerous parts, which is time-consuming, labor-intensive, and prone to causing secondary damage. This invention provides a transmission structure that facilitates maintenance. Utility Model Content
