An electric drive centrifugal seed metering device that can start and stop independently on demand

Abstract

The invention relates to an electrically-driven centrifugal seed-metering device with every row capable of realizing independent starting and stopping as needed. The electrically-driven centrifugal seed-metering device comprises a driving motor, a base plate, a seed-metering disc, a cover shell and a seed box, wherein the upper part of the cover shell is provided with a seed inlet which is connected with the outlet of the seed box; the periphery of the cover shell is provided with a plurality of seed-metering openings; the exterior of each seed-metering opening is provided with a rapid joint;the position of each seed-metering opening is provided with a seed-metering switch capable of realizing independent starting and stopping as needed; seed-metering switches are used for opening and closing the seed-metering openings; the seed-metering disc is arranged on the base plate; the cover shell is covered at the outer side of the seed-metering disc; the driving motor is arranged below the base plate and used for driving the seed-metering disc to rotate around an axis; the position of the center of the seed-metering disc upwardly protrudes to form a cone shape; and the upper surface of the seed-metering disc is provided with a plurality of raised parting strips. The electrically-driven centrifugal seed-metering device provided by the invention has the advantages of compact structure,high seed-metering efficiency, low cost and small seed breakage rate, can realize independent and real-time opening and closing of each seed-metering opening as needed, and is applicable to places for wide-width and highly-efficient sowing and accurate sowing in field edge and boundary areas for spheroidal-seed crops.

Description

technical field [0001] The invention belongs to the technical field of agricultural and forestry machinery, and in particular relates to an electric drive centrifugal seed metering device in which each row can be started and stopped independently as required. Background technique [0002] For traditional seeders, especially wide-width seeders, each individual seed meter is driven by the same power input shaft without an on-demand independent start-stop device, or the centralized seed meter is not equipped with an on-demand device. Independent start-stop device, when working, the action of each single seed meter or centralized seed meter is consistent, so it will cause different degrees of missed seeding and reseeding problems near the field head or border area . [0003] In addition, with the rise of creative landscape agriculture in recent years, it is sometimes required that the crops in the farmland be able to present a certain pattern or calligraphy and painting effect ...

AI Technical Summary

Problems solved by technology

Because the seed metering devices on the market cannot meet the requirements of sowing, mechanized planting cannot be realized, and it is still done manually, which is time-consuming and labor-intensive and has a high error rate
