The counter gear wheel 52 is rotatably supported at the tip end of a support rod 57 projecting from the rear end of the eating-end transmission case 46 toward the rear-side downward. The suppressing wheel 52 is formed in a truncated cone shape and is disposed on both left and right sides of the rear portion of the food portion. A biasing member 58 is interposed between the support rod 57 and the rear portion of the foodtransmission case 46 to press the counter-pressure wheel 52 downward. The bias member 58 is constituted by a rod and a spring fitted outside the rod, but may be biased by a torsion spring or the like, but is not limited thereto. The outer circumferential surface of the counter-pressure wheel 52, which is in contact with the paddy field surface, is made of a synthetic resin having water repellency, so that the soil is not smoothed. In this way, the surface of the soil added to the root portion of some species in the backing plate 51 together with the advancement is pressed by the repelling wheel 52, thereby making it easy to stably.

4 and 8, the sensor roller 54 is rotatably supported at the tip end of the support arm 59, and is disposed laterally or forwardly of the right and left centering tool 50. The middle portion of the support arm 59 is rotatably supported on the support case 49a (or the foodtop transmission case 46), and the other end of the support arm 59 is extended upward, Respectively. The other end of the sensor wire 61 is connected to an elevating and lowering hydraulic device (not shown) provided in the traveling portion 10. [

The elevating and lowering hydraulic device controls the lifting and lowering of the lifting and lowering cylinder so that the lifting and lowering cylinder is lifted and lowered so that the set height, that is, the depth of the food is set. The sensor roller 54 is lowered and the sensor wire 61 is extended and the elevating and lowering hydraulic device extends the elevating cylinder to lower the forming portion 40 To the set depth. On the other hand, when the rice planting area 50 sinks down due to the soft rice field, the sensor roller 54 rises and the sensor wire 61 is pulled, and the elevating and lowering hydraulic device reduces the elevating cylinder to raise the food compartment 40, Raise to the setting depth. Thus, the setting depth can be maintained and the eating posture can be stabilized.

As described above, the molding portion 40 is mounted to the rear portion of the passenger-travel portion 10 through the lifting mechanism 30, and the molding portion 40 is provided with the rotary type or crank type molding portion 70 The cell seedlings 80 are cut off by the feeding trough 45 one by one from the cell seedling mat 8 loaded on the seedling tray 41 by the rotation of the feeding tacking portion 70 in the vertical direction, It is possible to shorten the time taken for the transplantation and to improve the efficiency of the food. Since the cell seedlings 80 are released in the machine tool 50, even when the plant seedlings 80 are not the ground, they are affected by surrounding weeds and clay so that the food posture is not disturbed.

The vegetable transporter 1 is provided with an irrigation device 6 that is installed in the food bushing and the irrigation device 6 is connected to the tube accommodating tank 62 and the food compartment 40, An irrigation pump 64 for discharging water from the irrigation tank 62 in accordance with the timing of the food and a water jetting means for jetting the water discharged from the irrigation pump 64 in the vicinity of the eating position. , Watering can be performed at the same time, and the planting rate can be increased by reducing the seeding even when the plant is mechanically transplanted. In addition, it is possible to dispense at least the necessary quantity at the time of transplantation, and there is no unnecessary irrigation, and it is possible to carry out continuous transplanting work of a wide field by merely watering the irrigation tank once.

The watering nozzle 65 serving as the water jetting means is arranged in front of the lowermost portion where the food tanks 45 are rotated so that the soil of the rice field is shrunk and then the cell seedlings 80 are cooked, Is improved.

The irrigation nozzle 65 serving as the water jetting means may be irrigated after the food and the soil of the cell seedlings 80 when placed behind the lowermost portion where the food tanks 45 are rotated, ) And the surrounding soil are condensed with water to improve the adhesion.

Since the irrigation nozzles 65 are disposed on the lower side of the food tanks 45 to form a ridge on the rice field surface, the height of the rice field and the position of the water jet are constant, And the growth of seedlings after transplantation can be made almost constant.

Since the water tank 62 is disposed below the front step 23a in front of the left and right front wheels 12 · 12, it is possible to effectively use the space below the base frame 11 without blocking the front view have. In addition, it is possible to keep the front and rear balance well.

The present invention can be applied to a transplanting machine in which cell seedlings such as vegetables and flowers are placed on a seedling bearing table of a meal portion mounted on a rear portion of a traveling portion and cut and transferred by a rotary rotary or crank-type bath.
