Seed meter rotary seeding device

Abstract

A rotary seeding device for a seed metering device, belonging to the technical field of agricultural seeding machinery; comprising a seed metering device housing, a main shaft, a seeding tray, a seeding tray, a seeding tube, a dwell switch, a seeding switch, a dwelling cam, Seeding cam, etc.; when sowing, the seeds complete the process of filling, clearing and protecting seeds under the action of the seeding tray and the housing of the seeding device, and fall into the seeding pipe at the position of the seeding port along the seeding line. The tube slides outward to the position of the dwell switch. When the seeding tube moves to the position of the dwelling cam, the dwell switch is turned on, and the seeds slide into the seeding tube between the dwell switch and the seeding switch and wait near the seeding switch. For seeding, when the seeding tube rotates once and moves to the position of the seeding cam, the seeding switch is turned on, and the seeding is completed. The invention has a simple structure, can effectively reduce the horizontal speed of the seeds relative to the seed ditch, reduce the height of the seeding opening, improve the seeding performance of the seed metering device, and improve the 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
