Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a seeder capable of automatically covering soil. Background Technique

[0002] A seeder is a planting machine that takes crop seeds as the sowing object. Seeders for a certain type or kind of crop are often named after the crop type, such as a grain drill, a corn hill-drop planter, a cotton planter, a forage broadcaster, etc. The objects planted by the seeder are crop seeds or coated seeds made into pellet form, and it has the characteristics of accurate sowing amount and no damage to seeds.

[0003] The existing Chinese utility model patent with the reference publication number of CN218550621U discloses a seeder with a soil covering and backfilling function, including a support frame. A feeding pipe is inserted and connected in the middle position at the bottom end of the support frame. A soil covering piece body is arranged adjacent to one side position of the feeding pipe, and a combined square frame is arranged at the upper right position of the soil covering piece body. A steering clamping plate is connected to the front position of the soil covering piece body. In this utility model, through the arranged support frame, mounting base, hydraulic telescopic rod, rotating cylinder, soil covering piece body and combined square frame, when the hydraulic telescopic rod drives the combined square frame and the soil covering piece body to perform a telescopic action of moving forward and backward, after the soil covering piece body performs a swinging action, it will perform soil covering and backfilling treatment on the soil around the trench. By being able to quickly perform soil covering and backfilling treatment on the soil after sowing, it can effectively accelerate the germination and growth progress of seeds and the planting efficiency of the entire seeder.

[0004] The existing seeder generally backfills the soil through a baffle. The baffle is perpendicular to the subsoiler. This method cannot guide the soil to completely enter the gully, and the soil may be discharged from both ends of the baffle, resulting in insufficient soil coverage above the seeds and affecting the backfilling effect. At the same time, the existing seeder sows through a vertical pipe structure. This method may cause the soil to enter the end of the pipe structure and block the sowing pipe, affecting sowing.
