Abstract

The invention discloses a seed sowing device. A shell body is provided with a top plate, a first side plate and a second side plate, wherein a seed inlet is formed in the top plate, and both a first baffle and a second baffle are obliquely fixed between the first side plate and the second side plate; a seed outlet is formed in the lower end of the second baffle, a transmission shaft is rotatably connected with the first and second side plates, an active sowing wheel is fixed onto the transmission shaft, a slave sowing wheel sleeves the transmission shaft and is detachably connected with the active sowing wheel, sowing teeth arranged on the active and slave sowing wheels are different in size, and outer side faces of the active and slave sowing wheels are arranged over against the seed outlet; a sowing control rack is detachably connected to the second baffle and is arranged at outer circumferential sides of the active and slave sowing wheels in a covering manner; and the transmission shaft is in transmission connection with a driving device. The seed sowing device aims at solving the problem in the prior art seed sowing devices cannot simultaneously sow seeds of different grain sizes. The seed sowing device has the effect that the adaptability of the seed sowing device to seed grains is remarkably improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of core components of a seeder, in particular to a seed meter. Background technique [0002] The seed meter is the core component of the seeder, which is used to distribute the seeds in the seed box of the seeder evenly and equally. The sowing quality of the seeder directly depends on the performance of the seeder. In the prior art The seed wheel of the seed meter of the drill has a single structure, which can only realize the adjustment of the sowing rate of a single seed, and cannot be applied to seeds of different sizes. Larger-grained seeds and smaller-grained seeds often need to be replaced with different rowers. Only the seeder can meet the use requirements, and there is a lack of a seeder that can realize the same seeder to sow seeds of different particle sizes through simple parts adjustment. Contents of the invention [0003] For this reason, an embodiment of the present...
