DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling transplanter capable of adjusting the spacing between seedlings.

[0002]

2. Description of the Related Art There has been proposed a technique in which seedlings are provided side by side and seedlings are transplanted to a plurality of rows in one stroke. In some cases, the right and left seedling-planting rods move laterally relative to each other so that the gap between them can be adjusted.

[0003]

However, the seedling plant is
Since a relatively wide seedling mounting table is used, the movement of the seedling rods to the side approaching each other is limited, for example, a cabbage strip 60c.
It could not be applied to m and 30 cm between lettuces.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a traveling vehicle body 1 for propelling in a field, and two sets each of which is mounted on the traveling vehicle body 1 and which transplants seedlings into a plurality of rows. And two sets of seedling transplanting devices 2 and 3 are positioned in front and rear, and the rear seedling transplanting device 3 is placed between the plurality of rows where the previous seedling transplanting device 2 transplanted the seedlings. And a seedling transplanter configured so that the seedling transplanting apparatus can be changed between a state in which the seedlings are transplanted and a state in which the two sets of seedling transplanting apparatuses 2 and 3 are positioned to the left and right to transplant the seedlings.

[0005]

Since the present invention is constructed as described above, two sets of seedling transplanters 2, 3 for transplanting seedlings into a plurality of rows, respectively, are mounted on the traveling vehicle body 1 to provide a multiple-row seedling transplanter. Be composed. Each of the seedlings to be transplanted by each of the seedling transplanting devices 2 and 3 has a spacing of, for example, 60 cm. When the transplanting device 3 is placed in a state where the seedlings are to be transplanted in the middle of the strips, transplantation of a plurality of seedlings having a gap of 30 cm is performed.

[0006] When two sets of seedling transplanting devices 2 and 3 are positioned to the left and right to transplant a seedling, a plurality of seedlings with a spacing of 60 cm are transplanted.

[0007]

As described above, according to the present invention, it is possible to greatly control the interval between the seedlings to be transplanted in the seedling transplanter having a plurality of seedlings. In particular, since the rear seedling transplanting device transplants the seedlings to the center of the previously transplanted streaks, there is a feature that the seedlings with a narrow interval between the streaks can be transplanted.

[0008]

Next, an embodiment of the present invention will be described. FIG.
As described above, two sets of seedling transplanting devices 2 and 3 are mounted after the running vehicle body 1 to constitute a seedling transplanting machine. In the figure, a tractor is used for the traveling vehicle body 1, and thereafter, a worktable 5 is attached by a three-point link 4, and the worktable 5 can be moved up and down by a hydraulic cylinder 6.

As shown in FIGS. 1 and 2, a pair of right and left columns 7, 7 are provided at the rear of the work table 5, and each of the columns 7, 7 has a tip of four links 8, 8,. Are mounted so as to rotate about a horizontal axis, and these links 8, 8...
Are mounted on the horizontal axis. The upper link 8, 8, 8,
Hydraulic cylinders 10, 10 are provided between the work table 8 and the worktable 5, and the respective links 8, 8,...
Are made to move up and down in the same posture.

[0010] Four horizontal movement links 12, 1 up, down, left and right
2, 12, 12 are mounted on the right mounting frame 9 so as to rotate about the vertical axis, and the second mounting frame 13 is mounted on the rear end of each link 12, 12, 12, 12 about the vertical axis. The links 12, 12, 1
The second mounting frame 13 moves left and right in the same posture by the rotation of the gears 2 and 12.

The center of a pair of horizontally long rotating frames 14 and 14 is mounted on rolling shafts 15 and 15 after the left mounting frame 9 and the second mounting frame 13, respectively.
It is stretched by 6,16 to keep the balance. The power of the engine of the traveling vehicle body 1 is guided by the transmission shaft 17 into the transmission case 18 at the rear end of the worktable 5, taken out from the left end of the transmission case 18 by the transmission shaft 19, and reaches the inside of the left rotating frame 14. ing.
A transmission shaft 20 is provided between the right side of the transmission case 18 and the right rotation frame 14 so as to transmit the power in the transmission case 18 to the right rotation frame 14.

A pair of transplanters 21, 21, 21 and 21 are mounted on the left and right of the rear portions of the pair of rotating frames 14, 14, respectively, to constitute the seedling transplanters 2 and 3. Since each of the transplanters 21, 21, 21, 21 is configured in the same manner, one of them will be described below. That is, as shown in FIG. 2 and FIG.
And a seedling table 23 that moves left and right on it, and a seedling table 23
After that, the transplanting machine 21 is constituted by the seedling planting rod 24 which turns in a vertically long circular orbit. The transplanter 21 includes a gear box 22
With the input shaft 25 projecting forward from the front, the power within the rotating frame 14 is received to move the seedling mounting table 23 left and right, and the seedling planting rod 24 is turned. A planting case 26 extends obliquely and upward from the left side of the gear box 22, and a first turning case 27 is mounted inside the first case 27, and a second turning case 28 is mounted inside the tip of the first turning case 27. Second swivel case 2
The seedling rod 24 described above is attached to the end of 8. When the first swivel case 27 is vertically long, the second swivel case 27 and the second
When the swivel case 28 extends further up and down, and when the first swivel case 27 is long in the front and back, the second case is
The case 27 is folded. Further, the seedling planting rod 24 always keeps the same posture beyond the second turning case 28. Therefore, the tip of the seedling planting rod 24 turns up and down in a remarkably long oval orbit, takes out the seedling on the seedling mounting table 23 in the middle of descending, and the ditch generator 28 puts the seedling into a groove formed on the ground. Place (insert) the platform. Then, the left and right earth covering rings 30, 30 pass through, and the soil is buried on both sides of the seedling.

The interval between the seedling rods 24, 24 in each seedling plant 2, 3 is 60 cm, and the right seedling plant 3
2, the left seedling rod 24 is located at the middle rear of the seedling rods 24 of the left seedling plant 2 as shown in FIG.
Therefore, in this state, the seedling transplanter needs 30
Transplant 4 seedlings between cm strips. Also, as shown in FIG. 2, the rotation of the lateral movement links 12, 12, 12, 12 moves the seedling transplanting device 3 to the right. Then, the four transplanters 21
In one step, four seedlings are transplanted under a 60 cm streak.

When transplanting seedlings between the 60 cm streaks, the right seedling transplanting device 3 may be mounted on the right mounting frame 9. Also, the respective seedling-planting devices 2 and 3 are configured to be able to move to the left and right so that the center of the running vehicle body 1 and the center of the seedlings are aligned even when transplanting the seedlings between the 30 cm streaks. You can also. As shown in FIGS. 3 and 4, the groove generator 29 is formed in a boat shape when viewed from above, and the soil is pushed right and left to form a groove. When the groove generator 29 passes by, the groove collapses from the left and right and partially fills in naturally. In addition, the state of collapse differs depending on the soil quality and the hardness of the soil. In order to cope with this, in FIG. 3, the position of the groove generator 29 is configured to be adjustable with respect to the position where the seedling is separated from the seedling rod 24, and when the seedling is separated from the seedling rod 24, the left and right of the groove is adjusted. Therefore, the soil collapses toward this seedling. That is, FIG.
In the example, the groove forming device 29 is attached to a rod 31 extending rearward from the lower part of the transplanter 21 by a pair of front and rear links 32, 33, and the rear link 33 is extended upward to form a lever, which is a guide rod at a predetermined position. The lever 33 can be operated back and forth according to the speed and soil properties of the traveling vehicle body 1 or its hardness. Note that, as shown in FIG. 4, the opening degrees of the left and right blades 35 may be adjusted. Further, the front and rear positions of the groove generator 29 or the opening degrees of the blades 35 thereof may be automatically adjusted in conjunction with a throttle lever or a transmission of the engine.
