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, a roller 26 mounted on opposite shafts in front of the roller 1, a roller 27 mounted on a shaft vertically below the roller 1, and both rollers 26, 2.
The roller 28 is wound around a roller 28 which is mounted on a shaft diagonally below the outer side of the roller 7. The lower right bell) 21 is wound around a roller 29 mounted on opposing shafts below the roller l, a roller 30 mounted vertically below it, and a roller 31 mounted on a shaft diagonally below both of these rollers 29 and 30. It is something that is being passed around. The lower left belt 22 has a roller 32 mounted on a shaft below the roller 27, a roller 33 mounted on a shaft below the roller 28,
It is wound around a roller 34 mounted on a shaft vertically below the roller 33. The lower right belt 23 has a roller 35 mounted on a shaft below the roller 30, a roller 36 mounted on a shaft below the roller 31,
It is wound around a roller 37 mounted on a shaft vertically below the roller 36. The outer left belt 24 is wound around a roller 38 mounted on a shaft outside the rollers 2B 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 sorting transfer mechanism part a is a vertically running part between the rollers 26 and 27 of the upper left belt 20 and a vertically running part between the rollers 29 and 30 of the lower right belt 21, and the seedling receiving device B is transported in a close state. A central vertical conveyance path for holding seedlings that separates the transplant term P protruding from the delivery end from the following ones and transports it downward at predetermined intervals, and a detection system that detects the transplant term P in the conveyance path. It consists of a means lever and a sorting member E mounted in the lower space of the conveyance path, and the sorting member E rotates alternately to the left or right based on the detection of the transplant term P by the detection means. It is controlled to distribute the transplanted terms P that have arrived at the distribution unit E to the left and right. The branch transfer mechanism section includes roller 2 of the upper left belt 20.
The diagonally running portion between 7 and 28 and the diagonally running portion between the rollers 32 and 33 of the lower left belt 22 form a left inclined transportation path for holding seedlings. The branch transfer mechanism section b' forms a right side inclined conveyance path for holding seedlings by a diagonally running part between the rollers 30 and 31 of the lower right belt 21 and a diagonally running part between the rollers 35 and 36 of the lower right belt 23. Become. The supply transfer mechanism section C is connected to the roller 3 of the lower left belt 22.
The vertical running portion between 3 and 34 and the vertical running portion facing the outer belt 240 form a left vertical transportation path for holding seedlings. The supply transfer mechanism section C' is connected to the roller 36 of the lower right belt 23.
．． 37 and the opposing vertically running portion of the outer right belt 25 form a right side vertical transportation path for holding seedlings. As described above, the transplant terms P distributed to the left and right by the distribution unit E are divided into the branch transfer mechanism unit
Seedling holding left and right inclined transport path b', supply transfer mechanism part c,
The seedlings are supplied to the seedling planting devices At and Ao via the left and right vertical transportation paths for holding the seedlings cI, and are planted in two adjacent furrows as described above. The left and right rotation of the distribution unit E and the resulting distribution operation of the transplant terms P are performed as follows. The rotation of the main shaft 5, which rotates in conjunction with the drive wheel of this transplanter, is controlled by the sprocket 42. Chain 43. The shaft 45 is rotated via the sprocket 44. In this state, when one electromagnetic clutch 46 is turned on and the other electromagnetic clutch 46' is turned off, the sprocket 47 rotates at the same time as the shaft 45, and the chain 48. The shaft 50 is rotated counterclockwise in FIG. 1, that is, to the left, via the sprocket 49. As a result, the sorting member E, which is fixed to the shaft 50, is rotated to the left by a predetermined angle, and the seedlings P for transplantation are sent into the left-side inclined conveyance path holding the seedlings. On the other hand, when the other electromagnetic clutch 46' is turned on and the other electromagnetic clutch 46 is turned off, the rotation of the shaft 45 is caused by the rotation of the gear 5.
1.52, and rotate the shaft 53 to the right via the sprocket 54. Through the chain 55° sprocket 56,
The shaft 50 and the sorting body E are rotated by a predetermined angle in the opposite direction to the above, that is, to the right, and the seedlings P for transplantation are sent into the seedling holding right inclined conveyance path (see Figs. 1 and 3). . In the above, ON and OFF of the electromagnetic clutch 46 and 46'
The control of F is carried out as appropriate when the above-mentioned detection means detects the transplanting seedlings P passing through a predetermined position of the seedling-clamping central vertical conveyance path of the sorting and transfer mechanism section a. does not necessarily have to be immediately 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 distribution body E, so that the transplanting seedling P can be detected by the detection means. After passing the detection position of the seedling P, the distance between the detection means and the sorting member 8 is obtained from the encoder, etc. By configuring E to rotate in a predetermined direction, the detection means 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 at which the blades stop becomes a problem. For example, as shown in FIG. It is preferable to control the rotation angle of the blade. That is, the pulse signal is counted after the blade begins to rotate, and when a predetermined value is reached, the electromagnetic clutch 46 or 46' is turned OFF to stop the blade. That's a good thing. By the way, sorting transfer l! Measures department a, branch transfer mechanism department,

However, since it is the same as that of the upper left belt 20, the upper left belt 22, and the outer left belt 24, the explanation thereof will be omitted to avoid duplication. However, the lower 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 transport speed of the transplanting surface P by the seedling receiving device B is slower than that by the seedling planting devices A+ and At, and the distribution transfer mechanism section a, branch transfer mechanism section A, b'
The transport speed of the transplanting surface P by the seedling transfer device C, which is composed of the seedling transfer device C and the supply transfer mechanism portions c and c, is faster than that by the seedling receiving device B, and is approximately the same as that of the seedling planting devices A+ and Am. . Now, when the seedling receiving device B is supplied with a plurality of transplanting surfaces P in a close state, it is placed on the delivery end side 3t of the belt 3.
At the point where it protrudes from between the upper left belt 20 and the presser ring 4, it is separated from the following one at the upper end of the upper left belt 20, which is running faster than the belt 3, and is connected to the seedling clamping central vertical conveyance path of the sorting transfer mechanism section a. are transported at predetermined intervals.
