Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a carrier device for carrying a nursery box along a substantially horizontal direction, and a bed soil supply device for supplying bed soil to the nursery box in the path of the carrier device. The present invention relates to a seeding machine equipped with a seed feeding device that detachably mounts a seeding plate having vertical and horizontal guide holes to a seedling raising box to which bed soil is supplied and that supplies seeds to the guide holes of the seeding plate.

[0002]

2. Description of the Related Art Generally, when sowing seeds on a bed soil in a nursery box, as shown in JP-A-4-237437, a sowing plate having guide holes for supplying seeds vertically and horizontally is attached. .

[0003]

Depending on conditions such as the diameter of the guide hole, the size of the seed, and the wetness of the seed, the seed may bridge in the guide hole to cause clogging. In addition, when the guide hole is formed as a tapered hole having a narrow width downward, there is a problem that clogging is likely to occur. Therefore, when the guide hole is formed into a cylindrical guide hole having a wide seed receiving port as a means for suppressing the seed bridging phenomenon in the guide hole, the seed supplied to the hole spreads on the bed soil to a predetermined extent. There is an inconvenience that seeds cannot be sown in the position. An object of the present invention is to prevent clogging of a sowing plate while preventing seeds from falling on the soil.

[0004]

Means for Solving the Problems A characteristic feature of the present invention for achieving the above-mentioned object is a clogging for removing a clogging of a guide hole by protruding into a guide hole of a seeding plate rearward of a path of a seed feeding device. The point is that a removal device is provided.

[0005]

As shown in FIG. 1, the guide hole 19 of the seeding plate 19
The seeds that have clogged due to the bridging phenomenon in a are clogged by the rollers 22 having protrusions 22a that project into the guide holes of the seeding plate on the outer peripheral surface as a clogging removal device. To be removed.

[0006]

As a result of the above-mentioned constitution, the seeds fed through the seeding plate are made into the soil so that the guide hole of the seeding plate is formed in a cylindrical shape having a wide receiving port to prevent clogging. The seeds can be sown well at a predetermined position without being dislocated above.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 4, the seeder comprises a feeding device 2 for feeding the nursery box 1, a transport device 3 for transporting the nursery box 1 in a substantially horizontal direction, and a transport device 3 for transporting the nursery box 1 to the nursery box 1. A bed soil supply device 4 for supplying bed soil, a leveling device 5 for leveling the bed soil, a rotary brush 6 for scraping the surface of the bed soil, a seed supply device 7 for supplying seeds, a soil cover supply device 8 for supplying soil cover, Also, a watering device 9 for watering is arranged.

[0008] As shown in FIG. 1, the seedling raising box feeding device 2
The seedling-raising box 1 fed out from is loaded with a seedling-raising container 10 made of a pulp material integrally formed with a large number of pots 10b each having an opening 10a at the upper end in a vertical and horizontal directions. Bed soil is supplied, sowed and covered.

As shown in FIG. 4, the seed feeding device 7
Is disposed above the carrier device 3, and an endless rotating tool 11 is provided between the seed supply device 7 and the carrier device 3. This endless rotating tool 11 feeds and drives the seedling raising box 1 on the conveying device 3 in the conveying direction, and feeds seeds supplied from the seed supplying device 7 to each pot 10 in the seedling raising box 1.
a device for guiding to the opening 10a of the transfer device 3b.
It is provided along the transport direction of.

As shown in FIG. 3, the seed feeding device 7
At the bottom of the seed tank 12, a rotary feeding roll 13
Is arranged with the roll guide 14, and a large number of seed holders 13a provided on the outer periphery of the roll 13 receive the seeds from the seed tank 12, and the seed holder is positioned at the lowermost end by the rotation of the roll 13. It is adapted to supply from 13a to the opening 10a of each pot 10b through the endless rotating tool 11. Further, in the vicinity of the discharge port of the seed tank 12, there are provided a seed feeding brush 15, a sizing plate 16 for adjusting the number of seeds in the seed holding portion 13a, and a rotary brush 17 for sliding.

As shown in FIGS. 2 and 4, the endless rotating tool 11 is formed by winding a pair of endless chains 11a arranged so as to sandwich the nursery box 1 from the width direction around a plurality of rolling wheels 18. , An L-shaped joint fitting 20 so that a large number of seeding plates 19 each having a narrower tapered seed guide hole 19a corresponding to the opening 10a of the pot 10b can be rotated integrally with the chain 11a. It is installed between both chains 11a via a bolt 21.

The large number of seeding plates 19 are arranged so as to form a unit for each seedling raising box 1. Then, as the endless rotating tool 11 is rotationally driven, the seedling raising box 1 is hooked in the state of being engaged with the upper edge of the seedling raising box 1 and is fed and driven in the conveying direction of the conveying device 3. The transfer device 3 has a large number of idle wheels 3a arranged side by side in the transfer direction, and the feeding drive of the seedling raising box 1 is performed by the endless rotating tool 11 as described above.

As shown in FIG. 1, at the rear of the seed feeding device 7, there is provided a protrusion 22a as a clogging removing device which protrudes into the guide hole 19a of the seeding plate 19 to remove the clogging of the guide hole 19a. A rotating body 22 is provided. The rotating body 22 with protrusions is rotatably supported by a supporting frame provided upright on the frame 3b of the carrying device 3, and is hooked in the guide hole 19a of the seeding plate 19 to be rotationally driven. As shown in FIG. 4, a vibrating device 23 for vibrating the seedling raising box 1 is provided below the seed feeding device 7 and below the carrying device 3 at a predetermined position of the carrying route. . Furthermore, in the working area of the vibrating device 23, the floating regulating device 24 for acting on the seeding plate 19 loaded in the seedling raising box 1 to prevent the floating, is provided.
It is provided at a position corresponding to the vibration device 23.

As shown in FIG. 2, the lifting control device 24 is provided with a support frame 2 erected on a frame 3b of the transfer device 3.
4a, a chain guide 24b for pressing the chain 11a from above is attached. The chain guide 24b has substantially the same length as the nursery box 1, and is provided in each of the pair of chains 11a. A spring 24c for urging the chain guide 24b toward the vibration device 23 is provided between the support frame 24a and the chain guide 24b.

[Embodiment] In the above-described embodiment, the rotating body with the protrusion is illustrated as the clogging removing device. However, a flat plate with a protrusion having a plurality of protrusions that protrude into the guide hole 19a of the seeding plate 19 is vertically moved. It may be configured to be moved to remove the clogging. In the above embodiment, the seeding plate 19 is automatically mounted via the endless rotating tool 11, but it may be mounted artificially.

It should be noted that reference numerals are added to the claims for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
