Seeding unit rotary seed charge device

Abstract

The invention relates to a seeding unit rotary seed charge device comprises a seeding unit shell, a spindle, a seeding plate, a seed charge plate, a seed charge tube, a retention switch, a seed chargeswitch, a retention cam, a seed charge cam and the like. During sowing, the seed filling process, the seed cleaning process and the seed protection process of seeds are completed under the effects ofthe seeding plate and the seeding unit shell, the seeds fall into the seed charge tube at a seed charge port and outwardly slide along the seed charge tube to the position of the retention switch, the retention switch is turned on when the seed charge tube moves the position of the retention cam, the seeds slide into the seed charge tube between the retention switch and the seed charge switch andwaits for being charged at a position near the seed charge switch, and the seed charge switch is turned on to complete seed charge when the seed charge tube rotates a circle and moves to the positionof the seed charge cam. The seeding unit rotary seed charge device is simple in structure, capable of effectively reducing the horizontal speed of the seeds relative to a seed furrow, capable of lowering the height of the seed charge port, capable of improving the seed charge performance of a seeding unit and capable of increasing sowing quality.

Description

[0001] Technical field [0002] The invention relates to a rotary seeding device for a metering device, which belongs to the technical field of agricultural seeding machinery. Background technique [0003] Precision sowing is the development direction of sowing operations. The precision seed meter is the core component to achieve precision sowing. Its working process can be roughly divided into four parts: filling, clearing, protecting and throwing seeds. The seeding process is the whole work. The last process of the process is especially important in high-speed sowing operations. Each seed is required to have the same initial position and initial speed to ensure that the trajectory of the falling seeds is consistent, so that the time for each seed to reach the seed ditch is the same, and reduce The slipping and bouncing that occurs when the seeds are in contact with the soil interferes with the uniformity of the seeds. By controlling the seeding process, the uniformity and st...

Problems solved by technology

[0004] Since the linear speed of the hole or suction hole of the seed meter is much lower than the forward speed of the planter, and the distance between the hole or suction hole is much smaller than the plant spacing of the seeds, the falling seeds cannot obtain a sufficient backward speed when planting. , to effectively offset the forward speed of the seeder, which reduces the accuracy of seeding and affects the performance of seeding
