Description

Technical Field

[0001] This utility model relates to the field of agricultural implement structure technology, specifically to a vibrating disc harrow. Background Technology

[0002] The disc harrow is an important tool in traditional agriculture for tilling, breaking up soil, and preparing land. Its core principle is that a concave disc cuts into the soil, using traction to roll and break up soil clods. Current technologies generally rely on their own weight or external power to drive a vibrating device (such as a motor or eccentric wheel) to enhance soil penetration, but this has significant drawbacks: Power dependence issues: For example, the eccentric wheel driven by an electric motor used in patent CN 204906983 U is easily contaminated by soil in the harsh environment of farmland, has poor stability and high energy consumption: the power unit requires an additional energy supply, which increases the cost of use and the difficulty of maintenance.

[0003] The proposed "vibrating disc rake" achieves vibration by eliminating reliance on external power through mechanical structural innovation and utilizing the synergistic effect of an eccentric shaft and a fixed rod. This simplifies the structure and improves environmental adaptability, solving the problems of poor dynamic stability, high cost, and low soil penetration efficiency in existing technologies. Therefore, a vibrating disc rake is urgently needed to address these issues. Utility Model Content
