Description

Technical Field

[0001] This utility model belongs to the field of agricultural tillage equipment technology, and specifically relates to a multi-functional rotary tiller suitable for agricultural and industrial greenhouses. Background Technology

[0002] In current agricultural rotary tillers used for cultivation inside greenhouses, the process typically requires first rotary tilling and turning the soil, followed by ridging. This step-by-step operation increases the number of cultivation steps and reduces overall operational efficiency. The multi-step operation not only prolongs the work time but also increases the input costs of labor and machinery. Furthermore, separating rotary tilling and ridging can easily lead to uneven soil structure and irregular ridge shapes, affecting subsequent planting results.

[0003] These problems mainly stem from the fact that rotary tillers have a limited function and cannot complete the continuous operation of turning and ridging in a single job. To address these issues, some farmers use manual ridge-making or additional ridging devices to reduce the number of steps. However, manual ridging is inefficient, labor-intensive, and difficult to ensure consistent ridge shape; while adding ridging devices requires additional investment, is complex to adjust, and has limited applicability. Therefore, we aim to design a rotary tiller with a novel structure to solve this problem. Utility Model Content
