Pot body seed tray and pot body seeder

Abstract

The invention relates to a pot body seed tray and a pot body seeder, in particular to a pot body seed tray for accurately seeding in the pot body for cultivating rice seedling and a seeder adopting the seed tray. The invention solves the problems of low reliability for directly adsorbing seed by small holes of the seed tray, miss seedling and complex control structure of the seeder. In the pot body seeder, a stand is provided with a negative-pressure fan, a positive-pressure fan, a seed tray, a pot body seed tray and a pot body seed tray. A shell of the pot body seed tray and a bottom plate are spliced into a cavity; a vacuum pipe interface on the shell and a plurality of small holes on the bottom plate are respectively communicated with the inside space of the cavity; the vacuum pipe interface is connected with a vacuum control valve and the negative-pressure fan in series through a vacuum pipeline; the shell is provided with an air blowpipe interface communicated with the inside space of the cavity; the air blowpipe interface is connected with an air blow control valve and the positive-pressure fan in series through an air blow pipeline; each small hole of the bottom plate is provided with a sucker at least provided with a suction hole which is communicated with the inside space of the cavity and is provided with a slot at the external end.

Description

technical field [0001] The invention relates to a sowing disc for accurately sowing seeds in a pot body for cultivating seedlings and a sowing machine using the sowing disc. Background technique [0002] In the cultivation process of modern crops and flowers, in order to facilitate the transplanting of seedlings and save valuable good seeds, people generally use potted seedlings. Especially in the production of hybrid rice, the seedlings cultivated in pots are suitable for seedling throwing operations, which can improve the survival rate of seedling transplanting and reduce labor intensity. In recent years, people have invented a variety of vacuum adsorption type seeding equipment. For example, Chinese invention patent application publication CN 101116385A discloses that the patent application number proposed by Zhejiang University is 200710070632.5, and the name is called the technical scheme of "air-suction rice seedling planting device for industrialization", which inclu...

AI Technical Summary

Problems solved by technology

But its sowing suction head also has the following disadvantages: although for different sowing distances, the sowing suction head can replace and use different suction head bottom plates, and each suction head bottom plate adopts the structure of directly sucking seeds by small holes, which cannot guarantee that each The reliability of small holes to absorb seeds is easy to cause missed seeding

Furthermore, the control structure of the device is complex, the cost is high, and it is not easy to popularize and use in rural areas.
