It is provided on the support bases 76 and 76 so that it can be placed on the left and right sides. Furthermore, the tanks T, T; T, T are arranged in the space between the transmission cases 9, 9 and the body frame 2b in the left-right direction inside the body of the transmission cases 9, 9 for traveling and in a plan view of the body. It is placed at a position where the space of the aircraft can be used effectively. Therefore, the airframe can be made compact. Further, since the weight of the tank T for storing water acts near the left and right rear wheels 6, 6, the weight of the tank T surely acts on the rear wheels 6, 6, and the driving propulsion force of the rear wheels 6, 6 is achieved. Since the weight of the tank T arranged on the left and right sides near the traveling wheel (rear wheel) 6 that becomes the turning center of the aircraft when turning the aircraft is difficult to apply a turning drive load, Can be lowered smoothly and can turn smoothly. Further, the weight of the tank T does not significantly affect the pushing load of the steering handle 2 when the aircraft is turning, and the pushing load of the steering handle 2 is set to an appropriate load regardless of the weight of the tank T, that is, the capacity of water in the tank T. Can be maintained, and the turning operability can be improved. Conventionally, since the tank has been arranged at the center of the left and right sides of the airframe, even if the tank turns in either the left or right direction, the tank may increase the moment in turning, which may deteriorate the turning performance. However, by arranging the tanks T to the left and right and arranging the left and right so that they overlap or approach each other when viewed from the plane when turning, as in this embodiment, the turning can be smoothed and the turning performance can be improved. it can.

When the worker does not sit on the worker seat 70 and works while walking in the work space W outside the steering handle 2 on the rear side of the rear wheels 6, 6, the worker seat 70 and therefore the step 71. Therefore, tanks T, T; T, T may be placed on the step 71. In particular, when the heel is high and the rear wheels 6 and 6 are on the side where the rear wheels 6 and 6 are lowered, the transmission cases 9 and 9 are rotated downward on the front side. , 6 are positioned forward, and the aircraft tends to tilt rearward with the rear wheels 6 and 6 as fulcrums, and the longitudinal posture of the aircraft tends to become unstable. By placing T and T on the step 71 located on the front side of the tank support bases 76 and 76, the center of gravity of the entire aircraft can be moved forward, the posture of the aircraft can be stabilized, The planting posture can be maintained well, or the aircraft can be prevented from falling backward.

  In addition, at the front end of the aircraft, the planting strip position where the four planting bodies 25 plant the transplant in the planting process and the adjacent planting strip position and the pre-planting planting the transplant in the next planting process. A line-drawing marker 208 is provided to draw a line on the field at a total of 6 streak positions with adjacent planting streak positions where the transplant is planted in the process. By drawing a line on the field with this drawing marker 208, the transplanted plant does not obscure the transplanted location by planting the transplanted plant with a bulb or seeds such as oysters, so that the walking worker can transplant it. You can walk without stepping on the position. Further, since the drawing marker 208 is also drawn to the adjacent planting line position, it can be adjusted by running the aircraft while aligning the line drawing marker 208 with the line drawing line drawn in the previous planting process, and the desired route The aircraft can be driven with.

  As described above, the transplanter includes the traveling vehicle body 1, the steering handle 2 provided at the rear end of the aircraft, the left and right planted bodies 25 that move up and down to plant the transplant in the field, and the left and right planted bodies 25. The right and left supply devices 4R and 4L are provided to supply a transplant to the right and left, and each of the left and right supply devices 4R and 4L circulates a plurality of containers 49 for storing the implant in a predetermined loop-shaped locus. In the transplanting machine configured to supply the transplant from the container 49 to the planting body 25 at the supply position, an operator seat 70 is provided at a front position between the left and right supply devices 4R and 4L in the plan view of the machine body. The steering handle 2 is arranged at a rear position between the left and right supply devices 4R and 4L in view, and the worker walks behind the left and right supply devices 4R and 4L on both the left and right sides of the control handle 2. Implant implants into devices 4R and 4L A protective cover 202 that covers the planting body 25 is provided so that an operator in the work space W does not come into contact with the planting body 25, and the lower end of the protective cover 202 is grounded to plant the implant. It is configured to cover soil later. Then, the planting bodies 25, 25, 25, and 25 plant the transplant in the field while traveling forward with the pair of left and right front wheels 7 and the pair of left and right rear wheels 6 straddling the fence. The supply devices 4L and 4R supply the implants to the implants 25, 25, 25 and 25. An operator can perform an operation of sitting on the operator seat 70 and supplying the implants to the supply devices 4L and 4R.

  Therefore, the transplanter supplies the transplant to the left and right planting bodies 25 by the left and right supply devices 4R and 4L while the vehicle body is traveling by the traveling vehicle body 1, and the transplanted body 25 moves up and down to transplant into the field. Plant things. The replenishment work of the implants to the supply devices 4R and 4L is performed while the worker walks in the work space W behind one of the left and right supply devices 4R and 4L. A replenishment operation is performed, and an operator sitting on the operator's seat 70 performs the replenishment operation of the implant to the other supply devices 4R and 4L, and can be performed by two persons. At this time, a walking worker who works in one of the left and right work spaces W immediately before the work space W on the side that is easy to work depending on the planting condition or the field condition, such as the unplanted side or the opposite side of the house wall. The supply operator 4R, 4L can replenish the implant, and a rider who sits on the operator seat 70 has the operator seat 70 between the left and right supply devices 4R, 4L in plan view of the body. Since it is in a position where it can be replenished to both the left and right supply devices 4R and 4L by being placed in the front position, the walking worker does not replenish the implant to the supply devices 4R and 4L on the side where the implant is not replenished. Replenishment work can be performed. Therefore, the transplanting operation can be performed to the left and right supply devices 4R and 4L by two persons. Then, when the vehicle is turned at the end of the field or the like, a walking worker who works in one of the left and right work spaces W can immediately hold the control handle 2 at the rear end of the vehicle and easily perform the turning operation of the vehicle.

  Further, since the respective workers are positioned before and after the supply devices 4R and 4L that are long before and after being arranged on the left and right, one operator can replenish the implants to both the supply devices 4R and 4L on the left and right. Therefore, it is also possible for two workers before and after to assist each other to perform the replenishment work of the implant.

  Moreover, each planting body 25 is arrange | positioned under the rear-end part of supply apparatus 4R, 4L, and the right and left outermost planting body 25 (planting strip), and the ridge groove through which the left and right front wheels 7 and the rear wheel 6 pass are provided. Since the distance between the left and right sides is as narrow as 12 cm, there is a danger that a walking worker who walks in the groin may come into contact with the planted body 25, but the planted body 25 so that the walking worker in the work space W does not contact the planted body 25. Since the protective cover 202 is provided and the lower end of the protective cover 202 is grounded, for example, a toe of a walking worker can be prevented from coming into contact with the planted body 25, and the walking worker can reliably contact the planted body 25. The safety of work is improved. In addition, by grounding the lower end of the protective cover 202, the protective cover 202 also serves as a soil covering device that covers the implant after planting, so that it is not necessary to provide a special soil covering device, and the configuration can be simplified.

  As shown in FIG. 6, instead of the above configuration, one of the left and right (left side) supply devices 4L is arranged to be long in the left and right direction, and a walking worker mainly uses the left and right one (left side) supply device. It is possible to perform a replenishment operation of the transplant to 4L, and the rider can mainly perform the replenishment operation of the implant to the other side (right side) supply device 4R that is long in the front-rear direction. Thereby, since the walking worker can perform the replenishment work of the implant to the supply device 4L which is long right and left immediately after that, the replenishment work becomes easy. Further, the worker's seat 70 is configured to be rotatable about a vertical axis and the seat 70 is directed to the left and right (right) supply device 4R so that the rider can supply the left and right other (right). The replenishment work of the implant to the device 4R can be easily performed. Further, a container mounting frame 207 is provided in a space in front of the left and right (left) supply device 4L and to the side of the right and left other (right) supply device 4R. Both the walking worker and the walking worker can easily take out the transplant from the container C, and the replenishment work of the transplant is facilitated. Further, as shown in FIG. 7, the circumferential path of the container 29 of the supply device 4R on the left and right other side (right side) is bent and deformed so that the front part becomes longer to the left and right, and the front part of the supply device 4R If the left and right width of the vehicle is wider than the left and right width of the rear portion, the rider can easily replenish the implant to the supply device 4R.

  Further, as shown in FIGS. 8 and 9, instead of the above-described configuration, the worker seat 70 may be configured to be long from side to side so that a plurality of workers can be seated. Thereby, all the workers (two persons) can get on and carry out the replenishment work of the implant. At this time, if the worker's seat 70 can be slid to the left and right, the worker's seat 70 can be easily boarded on the step 71 through the wide space on the side where the worker's seat 70 is not moved from the front of the machine body. It can be seated on the service seat 70. In addition, a storage frame 209 for storing the implant is provided inside the loop-shaped circulation path of the storage body 29 of each supply device 4R, and an operator takes out the transplant from the storage frame 209 and replenishes the storage body 29. This makes it easier to replenish the implant. At this time, the lower portion of the housing frame 209 is provided with a discharge port 210 that discharges soil and dirt mixed together with the transplant, and guides the soil and garbage from the discharge port 210 to the vicinity of the farm scene through the discharge pipe 211. It is possible to discharge soil and garbage so that they do not touch the structure of the machine body such as the planting device 3. The arcuate portions of the side walls of the front end portion and the rear end portion of the storage frame 209 serve as an opening / closing door 212 for recovering the transplant remaining in the storage frame 209 at the end of the planting operation. The open / close door 212 is slid upward to open the open / close port, and the implant is taken out from the open / close port. Note that the door 212 can be fixed with the opening and closing of the opening and closing. Further, in the planting body 25, a bottomed hole forming plate 213 for forming a planting hole in the field is provided below the rear planting body 25R. Since this hole making plate 213 is provided only in the rear planting body 25R and not in the front planting body 25F, the planting body 25 is used when the machine body is advanced to enter the soil to open the lower part and from within the soil. When is moved up, it is difficult to receive the resistance of the soil, and the planting hole can be made appropriate without darkening the planting hole.

  In addition, FIG. 12 shows another planting form, and the left and right front wheels 7 and the rear wheels 6 that pass through the ridge grooves are formed in advance by forming ridge grooves at predetermined intervals (for example, 27 cm) in the field. Cross four ridges (for example, the tread of the left and right front wheels 7 and rear wheel 6 is set to 135 cm), and four ridges are simultaneously transplanted into the four ridges straddled by the transplanter, and the wheels 6, 7 pass. In the groin, there is one groin that will not be transplanted every 4th planting. Thus, by providing a ridge groove that is not transplanted at every predetermined interval, a management body by a management machine or a harvesting work by a harvester can be performed by passing a traveling body such as a wheel or a crawler through the ridge groove.
