CONSTITUTION: A drawing rod 34, a drawing rod supporting member 35, a seedling container driving shaft 36 and rocking pieces 37 are rocked by an output shaft of a crank to move a seedling container 68 at fixed intervals. A seedling inserting lever 63 of a planting mechanism 18 rocks a second swing plate 50, and a pressing plate 47 is dropped through a driving rod 49, a first swing plate 48, a second rotary rod 43 and a pressing lever 45 to push out a sweet potato seedling S from the seedling container 68. The pushed out sweet potato seedling is supplied from the seedling container to a seedling retaining tray of a separately sending mechanism and the seedling retaining tray is transported to plant the sweet potato seedling on a ridge by the seedling inserting lever 63. A planting operation is made easier than a conventional method in which an operator sets seedlings one by one on the seedling retaining tray. The transplantation of the seedling is efficiently automatized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sweet potato seedling machine for transplanting sweet potato seedlings, and more particularly to a seedling feeding device for supplying sweet potato seedlings to a feeding mechanism of the seedling seedling machine.

[0002]

2. Description of the Related Art Sweet potatoes are prepared by laying seed potatoes on a seedbed to produce buds, growing the buds, and cutting off the stems when they grow to about 30 cm. When transplanting, the cut end of the seedling should face downward and the base of the stem should be buried in the ground.

[0003] A conventional sweet potato seedling machine for mechanically planting this seedling comprises a planting mechanism for reciprocally moving the seedling rod up and down to plant sweet potato seedlings, and a feeding system for supplying sweet potato seedlings to this planting mechanism. It has a mechanism and performs planting work while supplying seedlings loaded in the seedling machine to the feeding mechanism.

By the way, since sweet potato seedlings are long and slender, and have no leaves and leaves and are easily bent, it is difficult to supply sweet potato seedlings to the feeding mechanism in the case of mechanical planting. For this reason, in the conventional seedling machine, the operator manually feeds the sweet potato seedlings one by one to the feeding mechanism, and the seedling rod receives the seedlings to plant them (for example, Japanese Patent Laid-Open No. 4-36107). .

[0005]

However, supplying a large amount of sweet potato seedlings to the feeding mechanism by hand in this way is not only a labor-intensive task, but the worker also carries out this work while operating the seedling machine. It was easy for me to get tired and I was hoping for improvement.

In order to solve such problems, the present invention loads a seedling container filled with sweet potato seedlings into a seedling feeding device,
An object of the present invention is to provide a sweet potato seedling machine equipped with a fully automatic seedling feeding device from supplying sweet potato seedlings to a feeding mechanism to planting.

[0007]

In order to achieve the above object,
The present invention provides a planting mechanism for reciprocating a seedling rod up and down to plant sweet potato seedlings, and a sweet potato seedling machine including a dispenser mechanism for supplying sweet potato seedlings to the planting mechanism. A seedling container transportation path is installed above, and a bottomless seedling container that holds one sweet potato seedling one by one between a number of parallel seedling holding plates is set horizontally in this seedling container transportation path. Look above the feeding mechanism, and install a raising and lowering seedling pushing plate that penetrates between the seedling holding plates above the seedling container, lower this seedling pushing plate in conjunction with the seedling rod, At the lower end, the sweet potato seedlings in the seedling container are pushed out from between the seedling sandwiching plates and fed to the feeding mechanism. And a seedling container lateral feed mechanism for intermittently transferring the seedling container by the installation interval.

[0008]

In order to plant sweet potato seedlings with the sweet potato seedling machine of the present invention, first, a seedling container filled with sweet potato seedlings is loaded in the seedling container transport path.

Then, the seedling pushing plate elevating mechanism lowers the seedling pushing plate to penetrate between the seedling holding plates of the seedling container, and the lower end of the seedling pushing plate pushes the sweet potato seedlings out of the seedling container and supplies them to the dispensing mechanism. Furthermore, this seedling is supplied from the feeding mechanism to the seedling cutting rod of the planting mechanism, and the seedling cutting rod holds the seedling and descends to plant it in the ridge.

After that, the seedling pushing plate rises and comes out above the seedling container, and the seedling container intermittently moves on the seedling container conveying path by the seedling container lateral feeding mechanism by the installation interval of the seedling holding plate. As a result, the adjacent sweet potato seedling is located below the seedling pushing plate, and the seedling pushing plate is lowered again to supply this seedling to the feeding mechanism. By repeating this, all the seedlings in the seedling container are sequentially taken out and transplanted.

Are formed in a straight line at a constant height (see FIG. 6).

Next, the operation of this embodiment will be described.

The seedling container 68 is mounted on the frame portion 32 of the seedling pushing mechanism 17, and power is transmitted from the engine 12 to the crank 14 via the mission 13. Then, the intermittent transmission mechanism of the crank 14 intermittently rotates the output shaft 21 to drive the feeding mechanism 16, the seedling pushing mechanism 17, and the planting mechanism 18.

First, driving of the feeding mechanism 16 and the seedling pushing mechanism 17 will be described. The output shaft 21 rotates the feeding mechanism input sprocket 24 via the output sprocket 22 and the chain 23. The input sprocket 24 intermittently drives the endless chain 59 via the horizontal axis 25 and the vertical axis 28 (see FIG. 2).

Next, driving of the seedling pushing mechanism 17 will be described.

The rotation of the vertical axis 28 causes the seedling pushing part disc 29 to rotate in the direction of arrow A in FIG.
9a contacts two hooks 34a of the pull rod 34, and pulls the pull rod 34 against a spring (not shown). As a result, the pull rod support member 35, the seedling container drive shaft 36, and the swing pieces 37, 37 simultaneously swing in the arrow B direction. At this time, it moves in the direction of the arrow B engaging with the recess 74 by a predetermined distance (see FIG. 7). In addition, the movement of the seedling container 68 causes the stop piece 38 to separate from the recess 74, and the adjacent recess 74
Engages.

Next, the protrusions 29a come into contact with one and two hooks 34a of the pull rod 34, and the swinging pieces 37, 37 swing in the direction of arrow C in FIG. 2 by a spring (not shown). Then, it is once detached from the recess 74 and engaged with the adjacent recess 74 (see the alternate long and short dash line in FIG. 7). At this time, the stop piece 38 is
4 to prevent backward movement of the seedling container 68.

Before the seedling container 68 is moved, the crank arm 65 is driven by the intermittent rotation of the output shaft 21,
The seedling rod 63 is swung upward by the crank arm 65 via the connecting lot 66 (see FIG. 8). When the seedling rod 63 reaches the vicinity of the top dead center, the hook 63a engages with the second swing plate 50, pulls the drive rod 49 downward by the second swing plate 50 with the shaft 51 as a fulcrum, and the urging force of the tension spring 53. The first rotating rod 42, the second rotating rod 43, and the pushing rod 45 are rotated against each other (FIGS. 3 and 4).
reference). Then, the pushing plate 47 is lowered to push out the sweet potato seedlings S from the seedling container 68, and the clip 62 of the seedling holding plate 60 is pushed.
And set the sweet potato seedlings S on the seedling holding dish 60 (see FIG. 5).

Next, when the seedling rod 63 starts to swing downward, the hook 63a of the seedling rod 63 and the second swing plate 50 are inserted.
Is disengaged from and the pushing plate 47 is quickly moved upward by the urging force of the tension spring 53 (see the alternate long and short dash line in FIG. 5).
Thereafter, as described above, the rocking pieces 37, 37 are used to attach the seedling container 68.
Moves.

In this way, the pushing plate 4 of the seedling pushing mechanism 17
The sweet potato seedlings S are set from the seedling container 68 to the seedling holding plate 60 of the feeding mechanism 16 by 7 and conveyed to the planting mechanism 18 by the rotation of the endless chain 13. Then, at the seedling take-out position, the sweet potato seedlings S are sandwiched by the planting claws 20 of the seedling seedling 63, and the seedling seedling 63 turns downward and is planted in the ridge. Thereafter, the same operation is sequentially repeated to plant the sweet potato seedlings S automatically (see the alternate long and short dash line in FIG. 8).

As described above, in this embodiment, the planting work becomes easier and the transplanting of seedlings becomes easier as compared with the conventional operator setting the sweet potato seedlings S in the seedling holding dish 60 one by one. Automation will improve efficiency.

By the way, since the field is a sloping ground, it is difficult to plant it with the sweet potato seedling machine 10, and when the sweet potato seedling S is too large or bent to fit in the seedling container, it is supplied. The planting work cannot be performed by the seedling device 15.

In such a case, the seedling feeding device 15 of the sweet potato seedling machine of the second embodiment removes the connection between the projecting pieces 33 of the seedling pushing mechanism 17 and the body 11 to insert the seedling feeding device 15. It can be removed from the machine 10. Therefore, the operator can manually set the sweet potato seedlings S one by one on the seedling holding plate 60 of the feeding mechanism 16. Sweet potato seedling S set
In the same manner as described above, the sweet potato seedlings S are planted from the seedling holding plate 60 by the planting nails 20 of the seedling rod 63.

Sweet potato seedling machine 10 automated as described above
When it is difficult to plant the sweet potato seedlings S with the seedling feeding device 15, the operator may manually set the sweet potato seedlings S on the seedling holding dish 60 one by one.

[0044]

As described above in detail, according to the present invention, the sweet potato seedlings are not manually supplied to the feeding mechanism one by one, but the planting mechanism is automatically operated from the seedling container via the feeding mechanism. And plant sweet potato seedlings. For this reason, the planting work of sweet potato seedlings becomes easier compared to the conventional worker setting each seedling holding dish one by one, and the planting work of sweet potato seedlings is automated by automating the transplanting of sweet potato seedlings. The efficiency of is significantly improved.
