First, a first embodiment shown in FIGS. 1 to 4 will be described. A ₁ and A ₂ are left and right seedling planting devices that plant seedlings for transplantation into two adjacent furrows. This device is configured to transport seedlings for transplantation in a closed grip as it rotates, and release them into the furrows at the lower periphery. It is of type. B is a seedling receiving device, in which a belt 3 is stretched between rollers 1 and 2, and the receiving end side 3 ₁ of the belt 3 is stretched between rollers 1 and 2.
A presser ring 4 is mounted on a shaft above the sending end side ₃₂ for transporting and sending out the seedlings P for transplantation mounted on the holding ring 4. Reference numeral 5 denotes a main shaft which rotates via a shaft 6, a sprocket 7, a chain 8, and a sprocket 7' which are interlocked with the drive wheels of the transplanter. This main shaft 5 has a sprocket 9 and a chain 1.
0, sprocket 11, shaft 12, sprocket 1
3. The shaft 16 is rotated via the chain 14 and sprocket 15, and the roller 1 fixed to the shaft 16 is rotated to run the belt 3. The shaft 16 simultaneously supports the gears 17, 18 and the shaft 19.
The presser ring 4 is rotated through (see Fig. 3). As a result, the seedling receiving device B receives the seedlings for transplantation which the worker has loaded onto the receiving end side ₃₁ of the belt 3.
is sent forward from between the delivery end side ₃₂ and the presser ring 4. C is a seedling transfer device that transfers and supplies the seedlings P for transplantation sent out by the seedling receiving device B to the seedling planting devices A ₁ and A ₂ . This seedling transfer device C includes a distribution transfer mechanism section a that distributes the transplant seedlings P sent out from the seedling receiving device B to the left and right, branch transfer mechanism sections b and b' that branch and guide the distributed seedlings, and It consists of supply transfer mechanism parts c and c' that supply the seedlings to the seedling planting devices A ₁ and A ₂ . These distribution transfer mechanism sections a, branch transfer mechanism sections b, b', and supply transfer mechanism sections c, c' generally consist of upper left and right belts 20, 21, lower left and right belts 22 disposed below them, 23, and outer left and right belts 24, 25 disposed outside of the belt, the belt is substantially symmetrical, and its details are as follows. Note that each of the above-mentioned belts is a rubber belt with protrusions. The upper left belt 20 is connected to the sending end of the seedling receiving device B;
That is, it is wound around a roller 26 mounted on opposite shafts in front of the roller 1, a roller 27 mounted vertically below the roller 1, and a roller 28 mounted on a shaft diagonally below both of these rollers 26, 27. The upper right belt 21 is wound around a roller 29 mounted on opposite shafts below the roller 1, a roller 30 mounted vertically below the roller 1, and a roller 31 mounted on a shaft diagonally below the outside of both rollers 29, 30. This is what is being done. The lower left belt 22 is wound around a roller 32 on a shaft below the roller 27, a roller 33 on a shaft below the roller 28, and a roller 34 on a shaft vertically below the roller 33. There is. The lower right belt 23 is wound around a roller 35 on a shaft below the roller 30, a roller 36 on a shaft below the roller 31, and a roller 37 on a shaft vertically below the roller 36. There is. The outer left belt 24 is wound around a roller 38 mounted on a shaft outside of the rollers 28 and 33, and around a roller 39 mounted on a shaft vertically below the roller 38 and just outside the roller 34. The outer right belt 25 is wound around a roller 40 mounted on a shaft on the outside of the rollers 31 and 36, and a roller 41 mounted on a shaft vertically below the roller 40 and right outside of the roller 37. The above-mentioned distribution transfer mechanism section a includes an upper left belt 20
The vertical running portion between the rollers 26 and 27 of the upper right belt 21 and the vertical running portion between the rollers 29 and 30 of the upper right belt 21 allow the seedling receiving device B to transport the seedlings P for transplantation in a close state and protrude from the sending end. , a central vertical transportation path for holding seedlings that is separated from the following ones and transported downward at predetermined intervals; and a seedling P for transplantation in the transportation path.
It consists of a detecting means D that detects the transport path, and a sorting member E mounted in the lower space of the transport path, and the sorting member E alternately moves to the left or right based on the detection of the seedlings P for transplantation by the detecting means D. It is controlled to rotate, and the seedlings P for transplantation that have reached the sorting body E are sorted left and right. The above-mentioned branching transfer mechanism part b is formed by forming a seedling holding and left inclined conveying path by a diagonally running portion between the rollers 27 and 28 of the upper left belt 20 and a diagonally running portion between the rollers 32 and 33 of the lower left belt 22. . The branch transfer mechanism section b' forms a right side inclined conveyance path for holding seedlings by a diagonally running portion between the rollers 30 and 31 of the upper right belt 21 and a diagonally running portion between the rollers 35 and 36 of the lower right belt 23. Become. The supply transfer mechanism section c is formed by a vertically running portion of the lower left belt 22 between the rollers 33 and 34 and an opposing vertically running portion of the outer left belt 24 to form a left side vertical conveyance path for holding seedlings. The supply transfer mechanism section c' is connected to the vertical running portion between the rollers 36 and 37 of the lower right belt 23 and the outer right belt 2.
5 and the opposing vertical running portions form a seedling-clamping right vertical conveyance path. As described above, the seedlings P for transplantation are distributed to the left and right by the distribution unit E, and the seedlings are transferred to the seedling clamping left and right inclined transport paths of the branch transfer mechanism units b and b′, and the seedlings of the supply transfer mechanism units c and c′, respectively. The seedlings are supplied to the seedling planting devices A ₁ and A ₂ through the clamping left and right vertical transportation paths, and are planted in two adjacent furrows as described above. The left and right rotation of the sorting unit E and the resulting sorting operation of the transplanting seedlings P are performed as follows. The rotation of the main shaft 5, which rotates in conjunction with the drive wheels of the present transplanter, rotates a shaft 45 via a sprocket 42, a chain 43, and a sprocket 44. In this state, one electromagnetic clutch 46 is
NO, when the other electromagnetic clutch 46' is turned OFF,
The sprocket 47 rotates at the same time as the shaft 45, and is connected to the shaft 50 via the chain 48 and sprocket 49.
is rotated counterclockwise in FIG. 1, that is, rotated to the left. As a result, the sorting body E fixed to the shaft 50 is rotated to the left by a predetermined angle, and the seedling P for transplantation is rotated to the left.
Transfer the seedlings to the left sloped transportation path that holds the seedlings. Conversely, when the other electromagnetic clutch 46' is turned on and one electromagnetic clutch 46 is turned off, the shaft 45
The rotation causes the shaft 53 to rotate clockwise via the gears 51 and 52, and further rotates the sprocket 54 and the chain 5.
5. Rotate the shaft 50 and the sorting body E by a predetermined angle in the opposite direction to that described above, that is, to the right, via the sprocket 56, and send the seedlings P for transplantation into the seedling holding right inclined conveyance path ( (See Figures 1 and 3). In the above, the electromagnetic clutches 46, 46'
The ON/OFF control is carried out as appropriate when the above-mentioned detection means D detects the transplanting seedlings P passing through a predetermined position on the central vertical conveyance path for seedlings in the sorting and transfer mechanism section a. The means D does not necessarily need to be directly above the distribution body E. That is, for example, by using an encoder or a rotation amount detector installed at a required position, it is possible to know the amount of movement of the transplanting seedling P above the sorting body E, so that the transplanting seedling P is After passing the detection position of the detection means D, information is obtained from the encoder or the like as to whether the seedling P has moved the distance between the detection means D and the sorting member E, and the seedling is sorted when it has moved. By configuring the member E to rotate in a predetermined direction, the detection means D can be installed at an appropriate position above the seedling-clamping central vertical conveyance path. Furthermore, if a roller with a simple shape without wings is used as the sorting body E, there may be a loss in the sorting operation due to slippage between the roller and the transplanting seedlings P. In order to avoid this, this embodiment employs a roller with blades. However, it is clear that by selecting and using an appropriate material for the distributing member E, it is possible to make a roller without blades or to have a desired shape. However, when using a roller with blades, the position where the blades stop becomes a problem, for example,
As shown in FIG. 4, it is preferable to control the rotation angle of the blade by obtaining a pulse signal from an encoder F provided on the shaft 36' of the roller 36 or the like. That is, it is preferable to count the pulse signals after the blade begins to rotate, and when the pulse signals reach a predetermined value, turn off the electromagnetic clutch 46 or 46' to stop the blade. By the way, the upper left and right belts 20 and 21, which constitute the distribution transfer mechanism section a, the branch transfer mechanism sections b and b', and the supply transfer mechanism sections c and c', the lower left and right belts 22 and 23 arranged below them, and The drive of the outer left and right belts 24, 25 arranged outside the belt is as follows.
This is done as follows. The rotation of the main shaft 5 of the lower left belt 22 rotates the shaft 60 and the roller 34 fixed thereto via the sprocket 57, chain 58, and sprocket 59. Also, sprocket 61, chain 62, sprocket 6
3. The shaft 68 and the roller 33 fixed thereto are rotated via the idle shaft 64, sprocket 65, chain 66, and sprocket 67. Furthermore, the shaft 72 and the roller 32 fixed thereto are rotated via the sprocket 69, chain 70, and sprocket 71. As a result, the lower left belt 22 is driven to run counterclockwise in FIG. Outer left belt 24 The rotation of the shaft 60 is changed in rotation direction by gears 73 and 74, and is transmitted to the idle shaft 75, and is transmitted to the shaft 79 and the above-mentioned shaft fixed thereto via a sprocket 76, a chain 77, and a sprocket 78. Rotate the roller 39. The rotation of the shaft 79 is controlled by a sprocket 80, a chain 81, and a sprocket 82.
The shaft 83 and the roller 38 fixed thereto are rotated through the shaft 83. This causes the outer left belt 24 to
The drive travels clockwise in the figure. Upper Left Belt 20 The rotation of the shaft 83 rotates the shaft 87 and the roller 28 fixed thereto via the sprocket 84, chain 85, and sprocket 86. Further, the rotation of the shaft 87 is controlled by the sprocket 88 and the chain 8.
9. Rotate the shaft 91 and the roller 27 fixed thereto via the sprocket 90. Furthermore, the shaft 91
The rotation of the shaft 95 rotates the shaft 95 through the sprocket 92, chain 93, and sprocket 94, and the roller 26 fixed thereto. As a result, the upper left belt 20 is driven to run clockwise in FIG. To drive the upper right belt 21, the lower right belt 23, and the outer right belt 25, the rotation of the shaft 6 is transmitted to the shaft 98 by changing the direction of rotation via gears 96 and 97, and the rotation is further transferred to the sprocket. 99, a chain 100, and a sprocket 101 to transmit the power to the main shaft 102.The structure and operation following this main shaft 102 are such that the main shaft 5 is connected to the upper left belt 20, the lower left belt 22, and the outer left belt 24. Since this is the same as in the case of , we will omit its explanation to avoid duplication. However, the upper right belt 21 is driven counterclockwise in the figure, the lower right belt 23 is driven clockwise in the figure, and the outer right belt 25 is driven counterclockwise in the figure. In this embodiment, the transportation speed of the seedlings P for transplantation by the seedling receiving device B is slower than that by the seedling planting devices A ₁ and A ₂ , and the transfer speed of the distribution transfer mechanism section a, branch transfer mechanism sections b, b', and The transport speed of seedlings P for transplantation by the seedling transfer device C consisting of the supply transfer mechanism parts c and c' is:
Faster and seedling planting device than that by seedling receiving device B
It is designed to be almost the same as that of A ₁ and A ₂ . Now, when multiple seedlings P for transplantation are loaded onto the seedling receiving device B in a close state, the belt 3
At the point where it protrudes from between the sending end side 3 ₂ and the presser ring 4, at the upper end of the upper left belt 20, which is running faster than the belt 3, it is separated from the following belt, and the above-mentioned sorting transfer mechanism part a The seedlings are transported along the central vertical transport path at predetermined intervals. By detecting the transplanting seedlings P being transported by the detection means D, the left and right alternate rotation of the sorting member E is automatically controlled, and the sorting member E is rotated in accordance with the direction of rotation. The seedlings P for transplantation that have reached E are distributed to the left and right, and the branch transfer mechanism parts b,
The seedlings are fed into the inclined transport path on the left and right sides of b′. Each seedling P for transplantation is transported along the sloped transportation path on the left and right sides holding the seedlings while maintaining a predetermined distance between the plants, and is then fed into the vertical transportation path on the left and right sides holding the seedlings in the supply transfer mechanism sections c and c' for transportation. and supplied to the seedling planting devices A ₁ and A ₂ . The seedling planting devices A ₁ and A ₂ continuously release each of the seedlings P for transplantation into two adjacent furrows at a predetermined spacing, and perform the desired planting. Next, a second embodiment shown in FIGS. 5 and 6 will be described. This second embodiment is the same as the first embodiment, except that the rotating means of the distribution member and its operating method are different from the first embodiment.
Only the differences will be explained. That is, in the first embodiment, in order to sort the seedlings P for transplantation, the left and right rotation of the sorting member E is linked to a drive wheel (not shown) of the present transplanting machine, and
The second embodiment is related to the ON/OFF operation of the electromagnetic clutches 46 and 46'.
Based on the detection of the seedlings P for transplantation by the detection means D' that detects the seedlings P for transplantation in the central vertical transportation path for holding the seedlings,
The motor 103 is controlled to alternately rotate the distribution body E' left and right, and according to the direction of rotation, the seedlings P for transplantation that have reached the distribution body E' are distributed left and right. The rotation of the motor 103 is caused by its output shaft 104
It is transmitted to the sprocket 105, the chain 106, the sprocket 107, the shaft 108, and the distribution member E' which is a roller with blades fixed to the shaft 108. The transplanting seedlings P distributed left and right by the distribution member E' are planted in two adjacent furrows in the same manner as in the first embodiment. Furthermore, a third embodiment shown in FIGS. 7 and 8 will be described. This third embodiment is also the same as the first embodiment except for the rotation means of the distribution member and its operating method, and therefore only the differences will be explained. do. That is, in the third embodiment, the solenoid 109

According to the direction of rotation, the seedlings P for transplantation that have reached the distribution body E'' are distributed to the left and right. The iron core 110 of the solenoid 109 and the distribution body E'' are connected by a link 111, Normally, as the iron core 110, which is in a protruding state due to traction by the spring 112, is pulled in against the spring 112 by energizing the solenoid 109, a distribution member consisting of a shaft 113 and a roller with blades fixed to this shaft 113 is moved.
Then, the transplant seedlings P distributed left and right by the distribution unit E'' are transferred to the two adjacent furrows in the same manner as in the first and second embodiments. It is something that can be planted.
