Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seeding machine, and more specifically, a seedling-growing container having a large number of pots each having an upper narrowed opening at the upper end is integrally formed in a row and a row in a seedling-raising box. A loading device is provided that can be loaded and moved substantially horizontally, and seeds are supplied to each of the pot portions to which the bed soil has been supplied by a bed soil supplying device provided at a midway point of the transportation of the transferring device. It relates to a seeder equipped with a seed feeding device.

[0002]

2. Description of the Related Art Conventionally, in a sowing plant provided with a bed soil supplying device for a downward spreading pot portion of this type, FIG.
The seeding work for raising seedlings was performed by the process shown in 0. 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, when scraping the bed soil with a rotating brush, if it is scratched with a strong force, the seedling raising container may be caught and lifted from the seedling raising box. It must be scraped off with a weak force, which reduces the depression of the bed soil from the opening surface of each pot part of the seedling-growing container, and even if the seed is fed into it, a part of the seed will be removed from each pot part. It has a drawback that it tends to protrude from the upper surface, and when the mask is removed from the nursery box, the seeds easily spill out from the opening. As a solution to this drawback, vibration is applied to the seedling raising container in a state where the bed soil is fed into the seedling raising container loaded with the seedling raising container, the floor soil in each pot portion is submerged, and in the upper part of each pot portion, It may be possible to form a space for accommodating seeds, but if such a vibration is applied, there is a drawback that the seedling raising container floats up due to the vibration and is displaced with respect to the seedling raising box. The object of the present invention is to eliminate the above-mentioned conventional drawbacks and to prevent the positional displacement of the seedling raising container, to form a space for storing seeds in each pot portion, and to securely store the seeds in each pot portion. It is an object of the present invention to provide a seeder that can be used.

[0004]

In order to achieve the above object, a seeding machine according to the present invention is provided with a seed guide hole corresponding to an opening of each pot portion between a bed soil supplying device and a seed supplying device. In a state where the mask equipped with the mask is loaded on the seedling raising container of each seedling raising box, a vibrating device that gives vibration to this seedling raising box is arranged, and in the working area of the vibrating device, the seedling raising box is loaded. It is characterized in that a lifting control means for acting on the mask to prevent the lifting thereof is provided at a position corresponding to the vibrating device, and its function and effect are:
It is as follows.

[0005]

In other words, according to the above-mentioned structure, the vibrating device vibrates the seedling raising box in the state where the mask is loaded on the seedling raising container of the seedling raising box, and at the same time, the lifting control means for the mask is applied to the mask. It acts to regulate the lifting of the mask. Since the mask has seed guide holes for all of the pots and is placed over the entire surface of the seedling raising container, the lifting of the mask can be effectively prevented by restricting the lifting of the mask. As a result, it is possible to settle the bed soil in each pot while preventing the seedling raising container from being displaced, and to form a space for accommodating seeds at the top of each pot.

[0006]

As described above, since a space for accommodating seeds can be formed in the upper part of each pot part, it is possible to provide a seeding machine which can surely store seeds in each pot part. ..
