Chain type seeding device suitable for seedling raising paper bowls and seeding method of chain type seeding device

Abstract

The invention discloses a chain type seeding device suitable for seedling raising paper bowls and a seeding method of the chain type seeding device. The problems that in the prior art, paper bowl type hole tray seeding efficiency is low, and the seeding quality is difficult to guarantee are solved. The chained seeding device comprises a seeding mechanism and a soil covering mechanism which are sequentially arranged at the upper part of a rack, and a pushing mechanism corresponding to the seeding mechanism and the soil covering mechanism is arranged at the lower part of the rack. The seeding mechanism comprises a seed box, a seed distribution hole disc and a seed falling hole disc which are sequentially arranged from top to bottom, the seed box transversely moves along the rack through a first transmission mechanism, and the seed falling hole disc transversely moves along the seed distribution hole disc through a second transmission mechanism and can be matched with the seed distribution hole disc to form a seed falling channel; the seeding quality is ensured. Through cooperation of the sowing mechanism, the soil covering mechanism, the pushing mechanism and the detection device, sowing, soil paving, soil covering and paper bowl replacement are completed in order, and the paper bowl type hole tray sowing efficiency is improved in the whole process. The seeding mechanism completes seeding of seedlings of various vegetables such as green Chinese onions, peppers and Chinese cabbages through mutual cooperation of a seed distributing hole disc and a seed falling hole disc, the seeding efficiency is improved, and the seeding rate is guaranteed.
