Technical Field

[0001] This utility model relates to the field of seeder component technology, and in particular to a composite seeder furrowing mechanism with impact overload protection function. Background Technology

[0002] A seeder is a planting machine that sows crop seeds. Seeders used for a certain type or type of crop are often named after the crop, such as grain strip seeders, corn hill seeders, cotton seeders, and hay seeders.

[0003] like Figure 4 The image shows a conventional furrowing mechanism installed on a composite seeder. Its main function is to turn the soil to both sides, creating a shape that is lower in the middle and higher on both sides, to facilitate sowing, irrigation, and soil drying. However, in this current structure, the vertical frame is fixed to the horizontal frame using U-bolts and fixing ribs. This leads to two problems: First, during ground movement, when the furrowing plow impacts a hard object, it is prone to impact damage, and the vertical frame is prone to bending and breakage. This requires the operator to use tools to replace the parts before continuing operation. Second, due to the aforementioned fixing method, adjusting the height and spacing of the two furrowing plows requires the operator to use hand tools, making the adjustment process time-consuming and laborious, increasing the workload of actual field operation and equipment debugging.
