Description

Technical Field

[0001] This utility model relates to the field of anti-weed entanglement in rotary tillers, specifically a rotary tiller with an anti-weed entanglement structure. Background Technology

[0002] Rotary tillers are an indispensable piece of machinery in modern agriculture, primarily used for tilling, breaking up, and leveling soil. Through high-speed rotating blades, they penetrate deep into the soil, breaking up large clods into fine particles, making the soil looser and more uniform. This improves soil structure, enhances aeration and water retention, and promotes root development and nutrient absorption. Furthermore, rotary tillers can mix fertilizers or organic matter into the soil during tillage, increasing fertilizer utilization and soil fertility. Using a rotary tiller before sowing provides an ideal growing environment for seeds, helping to improve germination rates and crop yields. For farmland requiring continuous cropping of different crops, rotary tillers can quickly and effectively remove crop residues from previous crops, reducing the likelihood of pests and diseases and accelerating soil recovery. In short, the rational use of rotary tillers can significantly improve agricultural production efficiency and promote sustainable agriculture.

[0003] In the existing technology, traditional rotary tillers mainly consist of an engine, rotary tiller shaft and blades, frame, suspension device, etc. The engine provides power and drives the blade shaft to rotate through the transmission system, so that the blades cut, turn and crush the soil. The suspension device is used to connect the rotary tiller to the tractor to ensure that it remains stable during operation, thereby completing the tilling of the land.

[0004] However, when using traditional rotary tillers, their blades are usually S-shaped or zigzag-shaped, which are easily entangled with weeds when tilling the land. When weeds are entangled on the blades, it increases rotational resistance, which may cause the machine to overheat or wear more quickly, damaging the equipment and affecting its service life. To address this problem, this utility model proposes a rotary tiller with an anti-weed entanglement structure. Utility Model Content
