That is, first, as shown in FIG. 10 (a), after the bed soil is supplied into the seedling-raising box 4 loaded with the seedling-growing container 3, the supplied floor-soil is the opening of each pot portion 2 of the seedling-growing container 3. 1
The soil is scraped and leveled with a rotating brush so as to be slightly recessed from the surface of the seed guide, and then the seed guide corresponding to the opening 1 of each pot portion 2 of the seedling-growing container 3 as shown in FIG. 10b. A mask 17 on a slab provided with holes 16 is loaded into the seedling raising box 4. After that, each pot portion 2 is sown by a predetermined amount through the seed guide hole 16 and the opening 1 of the mask 17. After its seeding, as shown in FIG. 10c, the mask 1
7 was removed from the nursery box 4 and then covered with soil, as shown in Figure 10d.

[0003]

However, in the above-mentioned conventional technique, both the work of loading the mask into the nursery box before sowing by the seed feeding device and the work of removing the mask after sowing are performed manually. The attachment and detachment work for each nursery box was troublesome and troublesome. An object of the present invention is to eliminate the above-mentioned conventional drawbacks and facilitate the work of attaching and detaching a mask.

[0004]

In order to achieve the above-mentioned object, a seeding machine according to the present invention has the seed feeding device disposed above a conveying device and corresponds to the opening of each pot portion. A plurality of masks having seed guide holes are provided, and the masks are attached to an endless rotating tool so as to be rotatable integrally with the rotating body, and the endless rotating tool is connected to the seed feeding device and the carrier. Arranged between the device and, as the endless rotation tool is driven to rotate, the mask is engaged in the upper part of the seedling raising box, hooks the seedling raising box, and in the conveying direction of the conveying device. The endless rotating tool is formed so as to be driven and fed, and its operation and effect are as follows.

[0005]

That is, according to the above construction, the endless rotating tool rotates between the conveying device and the seed supplying device located above the conveying device, and the rotating body rotates together with the rotating body. The mask of (1) engages with the upper part of the seedling raising box, hooks the seedling raising box, and feeds and drives in the conveying direction of the conveying device. When the seedling raising box is sent to a predetermined position in the engaged state, the seeds supplied from the seed supplying device pass through the seed guide holes of the mask and enter the openings of the respective pots for sowing. In this way, the mask is automatically engaged with the upper part of the nursery box along with the rotation of the rotating body of the endless rotary tool, and is also driven by hooking the nursery box in the transport direction of the transport device, so that the mask is manually operated. The mask does not have to be attached to and removed from the nursery box one by one, and moreover, the feeding of the nursery box can be ensured, and when the seeds are supplied, the mask guide hole and each pot part are misaligned. The seeds can be reliably delivered to the opening in a difficult state.

Therefore, since the mask can be automatically engaged with the upper part of the seedling raising box, not only the work of attaching and removing the mask can be facilitated but also the labor can be reduced, and the seed guide hole of the mask and each pot can be provided. The seeds can be reliably delivered to the opening in a state where it is difficult to shift the position of the parts, and moreover, the feeding of the nursery box can be made reliable, so that the seeds can be guided more stably and surely. It was possible to provide a convenient and excellent seeder.
