[0002] Currently, multi-row crop planting ditching devices on the market mainly consist of a power and transmission system and ditching operation execution components. From the perspective of the current technological status of traditional ditching devices, most multi-row planting ditching equipment on the market adopts a fixed structure design, making it difficult to adjust the depth, width, and row spacing of the ditching plow. In actual production, different crops have significantly different requirements for ditching parameters, making it difficult for traditional equipment to adapt quickly. Manual disassembly and replacement of components are often required, severely impacting operational efficiency. Regarding soil adaptability, traditional ditching devices face severe challenges. my country's soil types are complex and diverse, ranging from black soil in Northeast China and red soil in Southern China to sandy soil in Northwest China, with significant differences in soil texture, moisture, and hardness. Traditional ditching plows often adopt... Using a single material and a fixed structure can easily lead to problems such as difficulty in soil penetration and excessive resistance in hard soils, and the plow body suffers severe wear.
