In the above seeding device, in the case of haired seeds, the flow of the seeds in the seed hopper of the seeding machine is poor due to the cilia of the seeds. Therefore, the seeds do not collect well at the seeding position, and the seeds are left as they are. Difficult to sow grain by grain.
The present invention is to improve this, and a hair remover for seeds is installed in the preceding step of the seeding machine to remove cilia and then supplied into the seed hopper of the seeding device. Therefore, the device for removing the cilia of the seeds, which is arranged in the previous step of supplying the seeds into the seed hopper, will be described as follows.

That is, in FIG. 1, reference numeral (60) is a seed pan, which is supported by a stand (67) such that the bottom surface (60a) is inclined. In the saucer (60), there is a seed stirring body composed of a wire on a rotating shaft (61a) driven by a motor (61). And there is an air inlet (63) with a filter (64) stretched on the lower side of the tray,
The lid (65) on the higher side has an air outlet (66). The lid (65) is made of a transparent lid so that the inside can be seen through. The device for removing the ciliary body of the seed is constructed as described above, and the wire (6) is connected to the motor (61).
When 2) is driven, the seeds in the saucer are agitated and the saucer (60)
The seeds circulate vertically in the inside while the bottom of the saucer is inclined and the seeds are floated by the air from the air inlet (63). At this time, the cilia are removed by the wire (62), but the removed cilia are guided by the air from the air inlet (63) and discharged from the air outlet (66) to the outside of the pan. Since the filter (64) is stretched over the air inlet (63), the seeds in the saucer do not fall from the air inlet (63). Further, since the lid (65) is made of a transparent material, the degree of removal of seeds inside can be seen through from the outside.

In the present invention, the hair removing device as described above is installed in front of the seed hopper of the sowing machine.
A side wall (60b) on the side of the air introduction port (63) is provided with a seed supply gutter with an open / close valve (not shown), which is configured to face the seed hopper, and the open / close valve is used by driving the motor (61). Seeds from the seed supply gutter to the seed hopper. Alternatively, the seed tray may be used as a seed hopper and a vacuum nozzle may be moved toward and away from the seed tray to supply seeds. The seeds can be supplied to the seed hopper by any of the above structures.

[0013]

According to the invention of claim 1 of the present invention, by removing the ciliary body, the flow in the hopper of the seeding machine is improved, so that the seeds can be well gathered at the seeding position, and the seeds can be collected one by one. Sowing is possible. According to the invention of claim 2, since the bottom surface of the saucer is inclined, the seeds can be circulated while being floated, the removal of cilia can be promoted, and an air inlet port is provided on the saucer side with a low inclination, Since the air outlet is provided on the high side, the removed cilia can be easily discharged, and only seeds with cilia can be provided to the seed hopper. Further, there is a feature that the cilia can be easily removed from the seed by the stirring body.
