Description

Technical Field

[0001] The utility model relates to the technical field of agricultural seed drills, in particular to a soil turning roller assembly and an agricultural seed drill. Background Art

[0002] A seeder is a planting machine that sows crop seeds. Seeders used for a specific type of crop are often named after the crop, such as a grain drill, corn seed drill, cotton seed drill, or forage spreader.

[0003] Agricultural seeders typically require tilling the soil before sowing. Depending on the sowing requirements of different crops, the tilling depth often needs to be adjusted. In existing technologies, the tilling rollers have numerous tilling blades, and these blades can only be adjusted individually, which consumes considerable time, reduces work efficiency, and increases labor intensity. Therefore, we have developed a tilling roller assembly and agricultural seeder. Utility Model Content

[0004] The purpose of the present utility model is to provide a soil-turning roller assembly and an agricultural seeder, which can quickly adjust multiple soil-turning knives, facilitate the adjustment of the soil-turning depth according to needs, improve work efficiency, reduce the labor intensity of staff, and solve the problems raised in the above-mentioned background technology.

First, the driving device is powered off, and the shell is pulled outward. The inner side wall of the shell squeezes the spring while driving the locking rod to move to the outside of the locking groove. At this time, the annular plate can be grasped with one hand and the shell can be rotated with the other hand. The shell drives the circular plate to rotate through the locking rod, and the circular plate drives the rotating rod to rotate. The rotating rod drives the corresponding tiller blades to slide inward or outward through multiple linkage rods.
