And a partitioning device in which the bed soil is supplied by a bed soil supply device provided at a midway point of the transportation of the transport device. The present invention relates to a sowing machine equipped with a seed supply device for supplying seeds to a part.

[Conventional technology]

Conventionally, in a seeding plant equipped with a bed soil supply device for a downward spreading pot of this type, seeding work for raising seedlings has been performed by the process shown in FIG.

That is, first, as shown in FIG. 8 (a), after supplying the bed soil into the seedling raising box (4) loaded with the seedling raising container (3), the supplied bed soil is fed into the seedling raising container (3). Each of the pots (2) ··· is scraped and leveled with a rotating brush so as to be slightly recessed from the surface of the opening (1), and then as shown in FIG. 8 (b). , A thick plate-shaped mask (17) having guide holes (18) ··· corresponding to the openings (1) · · · of each pot (2) · · · of the seedling raising container (3) in the nursery box (4) Load it. After that, through the guide hole (18) and the opening (1) of the mask (17), each pot (2)
・ The seeds are sown in predetermined amounts. After the sowing, as shown in FIG. 8 (c), a mask (17) was placed on the nursery box (4).
And then covered with soil, as shown in FIG. 8 (d).

[Problems to be solved by the device]

In the prior art, both the work of loading the mask in the seedling raising box before sowing by the seed feeding device and the work of removing it with the mask after sowing were performed manually, so that the attaching / detaching work performed for each seedling raising box is troublesome and troublesome. Met.

The present invention aims to facilitate the work of attaching and detaching a mask.

[Means for solving the problem]

In order to achieve the above-mentioned object, the present invention is the seeding machine described at the beginning, in which a seed feeding machine for feeding seeds in synchronism with the transfer speed of the conveyed partition is arranged above the conveying device. In the lower position of the seed discharge part of the feeding machine, and at a height position above the partition part, a guide tool for guiding and guiding the seed discharged from the discharge part to the opening of the partition part is arranged. , The seed supply device is provided with a guide drive means for continuously moving the guide tool up and down in synchronization with a state in which the guide tool is in the lowered position when the guide tool and the opening overlap in the transport direction, and The guide drive means is interlocked with a drive mechanism of the seed feeding machine.

[Action]

The seedling raising box prevents the soil supplied to the seedling raising container from leaking to the outside even after the soil covering is supplied after the seed is supplied.
In addition, if a watering device is installed, the front, back, left and right side walls are set to a height higher than the top surface of the supply soil so that the water supplied by the sprinkling does not flow out from the surface of the soil cover. It is set.

Therefore, the height position of the opening of each partitioning portion is lower than the side wall upper edge of the seedling raising box, and by interposing the above-mentioned mask in the vertical gap between the opening and the seed discharging portion of the seed feeder, which is generated by that, The falling seeds are surely guided and guided into the opening.

That is, the mask for guiding the seeds functionally needs to be present above the partition portion only at the time of seed supply, and the above-mentioned characteristic configuration was created by focusing on this point.

That is, since the guide tool is always provided above and below the discharge section and the transfer partition section of the seed feeding machine, the supplied seed is always guided by the guide tool and falls, and is also transferred with this guide tool. When the openings overlap with each other in the up-down direction, in other words, the guide tool comes closest to the openings when seeds are supplied, so that the falling seeds can be reliably guided to the openings, and the guide tools in the raised position can be By setting the lower end to be higher than the upper ends of the side walls before and after the nursery box and continuously moving up and down, it is possible to prevent the carrier box for carrying and the guide tool from interfering with each other.

In other words, the work of wearing a conventional mask is not necessary, and the vertical movement of the guide tool, which is responsible for the function of the mask, makes it possible to automatically attach and detach the seed guide mechanism during seed supply. By reducing the attachment / detachment space, it is possible to shorten the transport process length.

[Effect of device]

Therefore, by theoretically examining the function / phenomenon of the mask, the seed guide mechanism during seed supply could be automated, eliminating the need for conventional manual work and facilitating mask attachment / detachment work. We were able to provide a more convenient and high-performance seeding machine by reducing labor, improving the quality of seedlings by eliminating forgetting mask work, and improving efficiency by shortening the process.

Further, as the means of the seed guide mechanism, it is only necessary to move the guide tool up and down, so that there is an advantage that the apparatus can be made compact.
