An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a soil supplying device, which is configured by a transport table 2 having a transport means (not shown) for transporting seedling containers (not shown). A soil feeding device 5 is provided above the transport table 2 for feeding bed soil or cover soil to the seedling containers being transported. The soil feeding device 5 is of a known structure, and is provided with a supply hopper 6 at the top, and a supply belt 7 below the supply hopper 6 that rotates parallel to the transport direction of the seedling containers.
A supply bucket conveyor 10 is provided near the side of the soil feeding device 5 to supply soil to the supply hopper 6 of the soil feeding device 5. The supply bucket conveyor 10 has a pair of frames 11 (Fig. 1), and a pair of upper and lower rotating shafts 12 are provided on the frames 11. One of the upper and lower rotating shafts 12 is driven and rotated by a conveyor motor 13 (Fig. 6).

The rotation of the conveyor motor 13 is directly or indirectly transmitted to a rotating shaft 12 provided on the upper part of the frame 11 .
A sprocket 14 is provided on each of the upper and lower rotating shafts 12 (FIG. 6), and an endless chain 15 is wound between the upper and lower sprockets 14. A number of buckets 16 for lifting the sieve soil are attached at predetermined intervals to the outer periphery of the endless chain 15.
A hopper 18 for laying sieve soil is provided on the lower part of the frame 11 on the upward rotating side of the bucket 16 (FIG. 1).

Above the loading hopper 18, a soil supplying device 20 is provided for supplying soil to the supply bucket conveyor 10 (Fig. 1). The soil supplying device 20 has a platform 25 on which a soil filling container 21, such as a flexible container, is placed. A flexible container is made by weaving thread-like members made of polyethylene, polypropylene, or other materials to form a cloth-like member, which is then formed into a cylindrical or square tubular bag shape. The soil filling container 21 has an openable/closable supply port 26 at its top and an openable/closable discharge tube 27 at its bottom.
The mounting table 25 is composed of an upper frame 30 on which the soil filling container 21 is placed, and a lower frame 31 that supports the upper frame 30.

As shown in Figure 4, the upper frame 30 connects an outer frame 32, the diameter of which is smaller than the outer diameter of the soil filling container 21, to an intermediate frame 33, the diameter of which is smaller than that of the outer frame 32, by connecting rods 34. A plurality of connecting rods 34 are arranged side by side in the circumferential direction of the intermediate frame 33. An inner frame 35 is provided inside the intermediate frame 33, the inner frame 35 having a smaller diameter than the intermediate frame 33 and formed with a diameter that allows the discharge tube portion 27 of the soil filling container 21 to be inserted from above. The inner frame 35 is fixed to the connecting rods 34.
The outer frame 32 and intermediate frame 33 of the upper frame 30 are positioned at approximately the same height when viewed from the side, but the inner frame 35 is set lower by a predetermined height than the outer frame 32 and intermediate frame 33 .

Therefore, the bottom surface of the soil filling container 21 is supported by the outer frame 32 and the intermediate frame 33, and a predetermined space K is formed between the bottom surface of the soil filling container 21 and the inner frame 35. The discharge tube portion 27 of the soil filling container 21 is positioned within the space K, making it easy to release the tie of the string member (not shown) that is blocking the discharge tube portion 27, or to tie the discharge tube portion 27.
The lower portion of a guide member 40 standing upward is fixed to the outer frame 32 of the upper framework 30. The guide member 40 forms an inclined guide portion 41 in which the portion above a predetermined upper and lower portion is tilted outward, and serves to guide the soil filling container 21 to the center of the upper framework 30 when the soil filling container 21 is placed on the upper framework 30 from above.

A plurality of upper legs 43 protruding downward are provided at predetermined intervals on the lower surface of the upper frame 30 at predetermined positions. In this embodiment, four upper legs 43 are provided. The lower ends of the upper legs 43 are provided with abutment portions 44 that open out like an umbrella.
The lower frame 31 of the mounting table 25 has a pair of fixed frames 45 connected by a connecting frame 46 to form a cubic space therein. In this embodiment, a pair of fixed frames 45 are provided, one at the front and one at the rear.
The fixed frame 45 is formed by welding and fixing both ends of a horizontal rod 48 in the left and right direction to predetermined upper and lower portions of a pair of left and right vertical rods 47 .
The connecting frame body 46 is formed by welding and fixing a predetermined front-rear intermediate portion of a pair of upper and lower front-rear horizontal rods 50 to both upper and lower ends of a pair of vertical rods 51 in the vertical direction.

Then, threaded shafts 54 are provided at both front and rear ends of the horizontal rods 50 of the left and right connecting frame bodies 46 , and the threaded shafts 54 are detachably fixed to the horizontal rods 48 of the front and rear fixed frames 45 by bolts 55 .
Therefore, the mounting table 25 can be separated into an upper frame 30 and a lower frame 31, and the lower frame 31 can be further separated into a fixed frame 45 and a connecting frame 46, facilitating packaging and transportation (FIG. 4).
Mounting rods 57 are provided in the left and right directions at predetermined positions on the lower frame 31, and a feed chute 58 is detachably attached to the mounting rods 57. The feed chute 58 has a cylindrical hopper section 59 at its upper part, and a guide gutter 60 at its lower part. The guide gutter 60 has an adjustment shutter 62 for adjusting the opening amount of a payout opening 61 of the hopper section 59.
The side plate 63 of the hopper portion 59 extends downward from the bottom surface of the guide gutter 60, and an engagement groove 64 is formed on the lower edge of the side plate 63, which is engaged with the mounting rod 57 from above.
The bucket conveyor 10 may have any configuration. In the bucket conveyor 10 of FIG. 1, the loading hopper 18 is configured as a single hopper, but the loading hopper 18 of FIG. 6 has a conveyor belt 70 provided therein.
In addition, reference numeral 71 denotes a soil recovery conveyor, which has a hopper section 72 at the top and a conveying belt 70 inside the hopper section 72.The conveyor recovers soil that has been discharged by the soil dispensing device 5 but does not enter the seedling container A, and returns it to the soil dispensing device 5.

(Operation of the embodiment)
The present invention has the above-mentioned configuration, and the supply bucket conveyor 10 is installed to the side of the soil delivery device 5 of the soil supplying device 1, and the input chute 58 of the soil replenishing device 20 faces the loading hopper 18 of the supply bucket conveyor 10.
A soil filling container 21 is placed on the upper frame 30 of the mounting platform 25 of the soil supply device 20, so that the soil in the soil filling container 21 flows into the hopper section 59 of the input chute 58, and is supplied from the hopper section 59 to the loading hopper 18 of the supply bucket conveyor 10.
The soil supplied to the loading hopper 18 of the supply bucket conveyor 10 is supplied to the supply hopper 6 of the soil dispensing device 5 of the soil supplying device 1, and the soil supplied to the soil dispensing device 5 is dropped from above into the seedling containers being transported by the transport table 2 of the soil supplying device 1.

Therefore, soil can be continuously supplied to the seedling containers by the soil feeding device 5 of the soil supplying device 1, the supply bucket conveyor 10 which supplies soil to the soil feeding device 5, and the soil supplying device 20 which supplies soil from the soil filling container 21 to the supply bucket conveyor 10.
In this case, conventionally, soil was manually replenished into the loading hopper 18 of the supply bucket conveyor 10, but in the present invention, gravity is used to continuously supply soil to the loading hopper 18 of the supply bucket conveyor 10 without using power, making soil supply work easier.

In addition, the soil dispensing device 5 only needs to be installed above the transport table 2 which has a transport means for transporting seedling containers, and may also be a soil dispensing device 5 serving as a bed soil or cover soil supplying device mounted on a sowing device which supplies soil, seeds, water, etc. and is installed at the sowing work site.
The soil supply device 20 is configured with a platform 25 on the upper part for placing a soil filling container 21, which is referred to by those skilled in the art as a flexible container, so that the soil can be allowed to fall naturally from the soil filling container 21 and supplied to the loading hopper 18 of the supply bucket conveyor 10, making it rational, simple and inexpensive to manufacture.

The soil filling container 21 has a supply port 26 formed at the top that can be opened and closed freely, so soil can be filled from the supply port 26 in advance with the discharge tube 27 closed, and a plurality of such soil filling containers 21 are prepared, and when a soil filling container 21 becomes empty due to the supply of soil to the seedling containers by the soil feeding device 5, it can be replaced with a soil filling container 21 filled with soil, making it possible to continuously supply soil to the seedling containers.
The mounting base 25 is composed of an upper frame 30 on which the soil filling container 21 is placed, and a lower frame 31 that supports the upper frame 30.The upper frame 30 is formed by connecting a circular outer frame 32 having a smaller diameter than the outer diameter of the soil filling container 21 to an intermediate frame 33 having a smaller diameter than the outer frame 32 by connecting rods 34, so that the underside of the soil filling container 21 is securely supported by the outer frame 32 and the intermediate frame 33.

A plurality of connecting rods 34 are arranged in parallel in the circumferential direction of the intermediate frame 33, so that the weight of the soil filling container 21 can be reliably supported. Incidentally, the soil filling container 21 is filled with about 0.5 to 1.5 tons of soil.
An inner frame 35 is provided inside the intermediate frame 33 of the upper frame 30, and is formed with a diameter smaller than the intermediate frame 33 so that the discharge tube portion 27 of the soil filling container 21 can be inserted from above. The outer frame 32 and intermediate frame 33 of the upper frame 30 are arranged at approximately the same height when viewed from the side, but the inner frame 35 is arranged a predetermined height lower than the outer frame 32 and the intermediate frame 33. Therefore, the bottom of the soil filling container 21 is supported by the outer frame 32 and the intermediate frame 33, and a predetermined space K is formed between the bottom of the soil filling container 21 and the inner frame 35. The discharge tube portion 27 of the soil filling container 21 is positioned within the space K, making it easy to release the tie of the string member (not shown) that is blocking the discharge tube portion 27 or to tie the discharge tube portion 27.

The lower part of a guide member 40 that stands upward is fixed to the outer frame 32 of the upper frame body 30, and the guide member 40 forms an inclined guide portion 41 in which the portion above certain upper and lower portions is tilted outward.Therefore, when the soil filling container 21 is placed on the upper frame body 30 from above, the soil filling container 21 can be easily guided to the center of the upper frame body 30.
In addition, since the soil filling container 21 is formed into a bag shape using a cloth-like material, when the soil filling container 21 is placed on the upper frame body 30, the sides of the soil filling container 21 deform so as to sandwich the guide members 40 from the left and right, and the guide members 40 also act as side support members for the soil filling container 21, stabilizing the position in which the soil filling container 21 is placed.

In this case, it is preferable for the upper end of the guide member 40 to be formed so as to abut against the side of the soil filling container 21 at least one-third of the height from the bottom of the soil filling container 21, as this stabilizes the position in which the soil filling container 21 is placed.
A plurality of upper legs 43 protruding downward are provided at predetermined positions on the underside of the upper frame body 30 at predetermined intervals, and an umbrella-shaped abutment portion 44 is provided at the lower end of the upper leg 43, so that the upper frame body 30 can be stabilized in the placement position simply by placing it above the lower frame body 31.
The lower frame 31 of the mounting table 25 has a pair of fixed frames 45 connected by a connecting frame 46 to form a cubic space therein, so that the hopper section 59 can be easily installed inside the lower frame 31.

Each fixing frame 45 of the lower frame body 31 has both ends of the left and right horizontal rods 48 welded to specific upper and lower portions of a pair of left and right vertical rods 47, so that the load of the soil filling container 21 is firmly supported.
Similarly, the connecting frame 46 has a pair of upper and lower front-to-rear horizontal rods 50 at a predetermined front-to-rear intermediate portion, and the upper and lower ends of a pair of upper and lower vertical rods 51 are welded to each other, so that it firmly supports the load of the soil filling container 21.
The lower frame body 31 has screw shafts 54 at both the front and rear ends of the horizontal rods 50 of the left and right connecting frame bodies 46, and the screw shafts 54 are detachably fixed to the horizontal rods 48 of the front and rear fixed frames 45 by bolts 55. Therefore, the mounting base 25 can be separated into an upper frame body 30 and a lower frame body 31, and the lower frame body 31 can be further separated into the fixed frame 45 and the connecting frame body 46, facilitating packaging and transportation.

Lateral mounting rods 57 are provided at predetermined positions of the lower frame 31, and a feed chute 58 is detachably attached to the mounting rods 57, so that the lower frame 31 can be packed separately from the feed chute 58, and the volume of the packed lower frame 31 can be reduced.
The feeding chute 58 has a cylindrical hopper section 59 at its upper part and a guide gutter 60 at its lower part. Therefore, when the fixed frame 45 on the front side of the lower frame 31 faces the loading hopper 18 of the supply bucket conveyor 10 and the feeding chute 58 is attached to this fixed frame 45, the guide gutter 60 of the feeding chute 58 can easily face the loading hopper 18 of the supply bucket conveyor 10, making it easy to install the lower frame 31 of the soil supply device 20.

When the upper frame 30 with the soil filling container 21 placed on it is placed on this lower frame 31, the installation of the soil supply device 20 is completed.
Then, the supply port 26 of the soil filling container 21 is opened and the adjustment shutter 62 of the input chute 58 is opened a predetermined amount, and the soil in the soil filling container 21 is replenished to the soil dispensing device 5 of the soil supply device 1 via the supply bucket conveyor 10.
In addition, an upper frame 30 is separately prepared on which a soil filling container 21 previously filled with soil is placed, and this filled soil filling container 21 and upper frame 30 are replaced with the soil filling container 21 and upper frame 30 that have already supplied soil to the soil dispensing device 5 of the soil supply device 1 and placed on the lower frame 31 so that soil can be replenished, thereby easily replacing the supplied soil filling container 21 with the soil filling container 21 before supply.

The method of placing the upper frame 30 with the soil filling container 21 placed on it on the lower frame 31 is arbitrary, but by inserting the forks of a forklift below the outer frame 32 of the upper frame 30, it can be easily lifted up and placed on the lower frame 31.
In addition, the order of operations such as assembling the upper frame 30, lower frame 31 and soil filling container 21 of the soil supply device 20 is arbitrary, and in addition to the above description, the loading chute 58 can be set on the lower frame 31, the upper frame 30 with the soil filling container 21 placed on it can be placed on this lower frame 31, and in this state, the forks of a forklift can be inserted from the rear of the guide gutter of the loading chute 58 below the upper cross rod 50 of the fixed frame 45 of the lower frame 31 from both sides of the loading chute 58 and lifted up, and the loading platform 25 and soil filling container 21 can be transported together toward the loading hopper 18 of the supply bucket conveyor 10.
