[0001] This utility model relates to the field of agricultural machinery, and in particular to a leveling device for ridging and sowing. Background Technology

[0002] For crops like peanuts grown on raised beds, a high degree of flatness is required before sowing. After sowing, the beds must be covered with soil and leveled again to ensure consistency with the sowing depth and thus guarantee uniform seedling emergence. Currently, widely used ridging and sowing machines in my country typically have combined ridging and sowing functions, allowing for integrated operations with high efficiency and low operating costs. The structure of the leveling device for ridging and sowing can be referenced in Chinese Utility Model Patent Application No. CN201220369002.4, entitled "A Ridging and Shaping Component." Existing leveling devices for ridging and sowing are mostly fixed structures, which are insufficient to meet the needs of complex conditions such as small fields in hilly and mountainous areas with heavy, clayey soil. Utility Model Content
