The box cover 541 is hinged to one end of the box body 542, and the other end of the box cover 541 and the other end of the box body 542 are locked by a fastener.

The open-close type connecting structure is convenient to install and maintain, the using quantity of fasteners is reduced, and the assembling and maintaining workload is reduced.

Wherein, a movable baffle 5428 is arranged below the seed inlet 5421. The flapper 5428 controls the amount of seeds that fall from the funnel and avoids plugging the cavity in the box 542.

Wherein a seeding conduit 55 is arranged below the outlet 5422. The tail end of the seeding guide pipe 55 is close to soil, so that seeds coming out of the precision seed dibbling box 54 can be prevented from being blown away by wind and falling into the excavated pit; the seeding conduit 55 ensures the accuracy of seed dropping.

Wherein a cloth bag is further arranged below the recovery opening 5423. The sack is economical and practical, light in weight, and it is convenient to be connected with retrieving mouthful, can also retrieve unnecessary seed, avoids extravagant.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and these modifications or substitutions do not depart from the spirit of the corresponding technical solutions of the embodiments of the present invention.
