  On the other hand, the tip of the operation wire 40 configured to be pulled when the link mechanism 9 is moved upward to move the seedling planting device 10 is connected to the rotating portion 60 at the base of the marker 32, When the link mechanism 9 is moved up to move the planting device 10, the left and right line drawing markers 32 and 32 are in the stored positions as shown in FIG. 3, and the seedling planting device 10 is moved down for the seedling planting operation. When the link mechanism 9 is moved downward, either the left or right operation wire 40 is loosened by a well-known left / right selection mechanism so that the marker 32 on the selected side becomes the drawing action position as shown in FIG. Yes. The left and right line drawing markers 32 and 32 are rotated together with the left and right preliminary seedling mounting bases 24 by the rotation of the left and right preliminary seedling mounting bases 24 to be in the operation position and the storage position.

  Here, the configuration of the left and right line drawing marker 32 will be described in more detail. The other end side of the operation wires 40 and 40 is connected to the piston portion 50a of the hydraulic cylinder 50 whose inner wire 40a drives the link mechanism 9 to move up and down. 40 b is connected to the cylinder portion 50 b of the hydraulic cylinder 50. Therefore, the seedling planting device 10 is raised from the paddy field surface when turning on the headland during the rice transplanting operation. At this time, the piston portion 50a of the hydraulic cylinder 50 protrudes from the cylinder portion 50b, and the operation wire 40 · Forty inner wires 40a are drawn. As a result, the drawing marker 32 lying sideways and in the drawing action posture is raised and raised to switch to the non-drawing action posture.

  On the other hand, the pair of left and right operation wires 40 and 40 are locked so that the inner wires 40a and 40a of the wires 40 and 40 are not pulled back even if the piston portion 50a of the hydraulic cylinder 50 is retracted into the cylinder portion 50b. A lock mechanism L is provided. When the turning at the headland is completed and the seedling planting device 10 is lowered, if the operation wires 40 and 40 are locked by the lock mechanism L, the drawing marker 32 does not move to the drawing action posture. Further, when the operation wires 40 and 40 are in an unlocked state by the lock mechanism L, the drawing marker 32 moves to a sideways drawing action posture by the bias of the spring 39. However, the lock mechanism L does not lock against the operation in which the piston portion 50a of the hydraulic cylinder 50 protrudes and pulls the inner wire 40a toward the hydraulic cylinder. The locking mechanism L can be operated to lock both the left and right inner wires 40a, and can be operated so that only the left and right ones can be automatically and alternately switched every time the seedling planting device 10 is lifted. it can. Moreover, it can be operated so that both the left and right inner wires 40a and 40a are not locked. Therefore, by the above operation, both the left and right drawing markers 32 can be pulled up to bring the left and right drawing markers into a non-drawing action posture. Therefore, by the above operation, one of the left and right drawing markers 32 can be automatically switched to bring the one of the left and right drawing markers into the drawing action posture, and both the left and right drawing markers 32 and 32 can be set to the drawing action posture at the same time. You can also.

  The lock mechanism L has two solenoids 53 and 53 (two drawings) provided on one side thereof with two wire insertion holes 52 and 52 through which the hydraulic cylinder side of the inner wires 40a and 40a of the operation wires 40 and 40 is inserted. , Only one of them is shown), and holes 55 and 55 are provided in which the plungers 54 and 54 project and sink. Also, when the solenoid coil 53 is not energized, the plungers 54 and 54 of the solenoid 53 and 53 are projected from the holes 55 and 55 by the springs 56 and 56, respectively, and the tip of the plunger is connected to the end of the inner wire 40a on the hydraulic cylinder side. Engage with the stepped portions 57 'and 57' of the slider pins 57 and 57 to prevent the inner wires 40 'and 40' from moving to the drawing marker side. When the solenoid coil is energized, it is immersed in the holes 55 and 55 against the springs 56 and 56 to allow the inner wires 40a and 40a to move toward the drawing marker.

  The switching operation of the solenoids 53 and 53 is performed by a marker switch SW1 shown in FIG. This switch SW <b> 1 is provided so as to be alternately switched every time the operation lever 17 is operated to intermittently operate transmission to the seedling planting device 10. A main switch SW0 is provided between the marker switch SW1 and the power source (battery) BT. Further, marker lamps LMP (R) and LMP (L) are provided which blink in synchronization with the solenoids 53 and 53 being turned on and off. Further, a circuit for communicating both circuits is provided between the marker switch SW1 and two circuits connected to the solenoids 53 and 53, and the marker operation changeover switch SW2 is provided on the circuit. When this marker operation changeover switch SW2 is in the OFF state, the marker switch SW1 is switched by the turning-on / off operation of the operation lever 17 at the time of turning, and the two solenoids 53, 53 are alternately excited, and the left and right drawing markers 32, 32 is in an operating state in which only the left and right sides fall alternately and move to the drawing action position. When the marker operation changeover switch SW2 is in the on state, the two solenoids 53 and 53 are both energized regardless of whether the marker switch SW1 is switched by the turning on / off operation of the operation lever 17 during turning. The markers 32 and 32 are in an operating state in which both the left and right sides fall down and move to the drawing action position.

  Reference numeral 70 denotes a wrinkle marker, which is provided with a marker body 72 of a conspicuous color by bending the tip of the housing 71 at a right angle. The base end portion is provided with a hole 73 and a bowl-shaped portion 74. In order to attach the heel marker 70 to the airframe, the base end portion of the heel marker 70 is attached to the tip of the pipe 61 of the drawing marker 32 in a state where the holding portion 67c of the locking pin 67 of the drawing marker 32 is pulled. When the hook portion 74 is inserted, the grip portion 67c is released at a position where the pin portion 67a of the locking pin 67 fits into the hole 73 of the hook marker 70, and the state shown in FIG. It is attached to the tip of 32. Conversely, when removing the eyelid marker 70, the eyelid marker 70 may be pulled out from the tip of the pipe 61 while the gripping portion 67 c of the locking pin 67 of the drawing marker 32 is pulled.

  Here, the positional relationship with respect to the aircraft when the drawing marker 32 and the heel marker 70 are moved down to the operating state will be described with reference to FIG. 13. Since this riding type rice transplanter is a 6-row planting, the left and right center C In contrast, 6 seedling rows P are planted in a symmetrical manner. At this time, the line-drawing marker body 32a of the line-drawing marker 32 draws a line at a position where the body hits the left and right center of the body when the seedling is planted on the side of the row of 6 seedlings currently planted. Further, as shown in FIG. 13, when the marker body 72 of the heel marker 70 is aligned with the heel, the aircraft is run between the six seedling rows P ... currently planted and the heel A2, and the six seedlings ( The seedling can be planted so that the distance at which the virtual planting position P ′) is planted can be maintained. In general, when the interval is 30 cm, the distance between the left and right center C of the aircraft and the drawing marker body 32a is 180 cm, and the distance between the left and right center C of the aircraft and the marker body 72 is 285 cm.

  41 is a alignment marker for aligning the seedling planted in the previous process and confirming the position of the aircraft. Next, a description will be given of performing rice transplanting work with the above-described riding type rice transplanter. First, the granular fertilizer is put into the fertilizer tank 16 of the fertilizer application apparatus, the seedling is placed on the seedling stage 12, and the seedling box containing the seedlings is placed on each of the preliminary seedling stages 24.

  For example, in order to perform the rice transplanting work in a farm field (paddy field) as shown in FIG. 11, the paddy marker 70 is attached to the tip of the right line drawing marker 32, and the seedling planting device 10 is raised from the farm road RD. Enter the field through the field entry / exit ENT and move to the opposite side A2 side. Then, when the marker operation changeover switch SW2 is turned on and the operation lever 17 is operated to the lowered position and the seedling planting device 10 is lowered until each of the leveling floats 14, 15, 15 contacts the mud surface, Both the markers 32 and 32 move downward in the direction of the arrow B to reach the drawing action position (after confirming that both the left and right drawing markers 32 and 32 are in the drawing action position, the marker operation switch SW2 is turned off. deep). At that time, planting travels along the heel A2 while steering so that the marker body 72 of the heel marker 70 mounted on the right side is positioned on the heel line of the heel A2. At this time, since the left and right drawing marker bodies 32a and 32a are in a drawing action state, the lines L1 and L2 are drawn respectively on the left and right sides of the machine body. In addition, since the marker body 72 of the saddle marker 70 is provided in front of the control seat 8, the operator can easily confirm it while facing forward.

  Then, after planting and traveling from the heel A3 side along the farm road RD to the heel A4 side facing it, the planting operation is stopped, the seedling planting device 10 is raised and turned to the next stroke. At this time, since the seedling planting device 10 is raised from the mud surface, the left and right drawing markers 32 and 32 in the drawing action posture are pulled up and stand up. At this time, the wrinkle marker 70 is no longer used in this field and may be removed.

  After turning, the seedling planting device 10 is lowered by the operation lever 17 and the planting operation is performed in the same manner, but the center mascot 53 provided at the center of the left and right of the aircraft is positioned on the center line L2 drawn in the previous stroke. When planted and traveled from the heel A4 side to the heel A3 side, seedlings can be planted at a predetermined interval (30 cm) from the adjacent strips of the seedlings planted in the previous stroke. At this time, only the drawing marker body 32a on the heel A1 side (right side) is switched to the drawing action state, and the center line L3 is drawn.

  Thereafter, when the seedling planting device 10 is lowered to the mud surface by turning, the drawing marker 32 on the side opposite to the side in the drawing stroke posture in the previous stroke is automatically switched to the drawing drawing posture. This is because the marker switch SW1 is switched in conjunction with the cutting operation because the operation lever 17 to the seedling planting device 10 is always turned off when the next stroke is started.

  In this way, when traveling in a reciprocating manner toward the 畦 A1 side and the remaining one stroke is reached with the 畦 A1, as shown in FIG. 12, along the 畦 A3 from the entrance ENT side toward the 入口 A2 Next, we planted and traveled from the た A3 to 畦 A4 and then headed to the headland from 畦 A2 to 畦 A1. Finally, the process that has been left for one stroke with the fence A1 is planted along the fence A1 toward the entrance ENT and exits from the entrance ENT onto the farm road RD. During this round planting, the left and right drawing marker bodies 32a and 32a are switched to the non-drawing action state (the main switch SW0 is turned off), and the alignment marker is on the border line or on the adjacent planting seedling. It steers so that the body 51a is located. If it does as mentioned above, an unplanted area does not arise in the four corners of a farm field, but efficient rice planting can be performed.

  On the other hand, at the same time as the above planting operation, the fertilizer is applied to the granular fertilizer in the field on the side of the seedling planting position. Then, when the seedlings on the seedling table 12 become small during the planting operation, the aircraft is stopped and the pedal 27 is depressed to move the preliminary seedling table 24 to a position rotated 90 degrees from the position shown by the solid line in FIG. The operator rotates and fixes the seedlings so as to seed the seedlings from the seedling box on the preliminary seedling stage 24 with the seedling seeding plate 26 and supply them to the seedling stage 12. If the preliminary seedling stage 24 is rotated rearward in this way, the distance between the preliminary seedling stage 24 and the seedling stage 12 in the left and right preliminary seedling units 18 and 18 is shortened, so that workability is very good. .

Further, when the rice transplanting operation is advanced and the seedlings of the left and right spare seedling placing parts 18 and 18 are lost, the front end of the machine body is brought close to the cocoon and the spare seedling placing table 24 is returned to the position shown by the solid line in FIG. A seedling is supplied to the seedling stage 24. When the rice transplanting operation is completed and the machine is stored in a barn or the like, the left and right auxiliary seedling mounting bases 24 are stored in the interior of the body rotated approximately 180 degrees to the end position of the arrow C in FIG. Since the left and right preliminary seedling mounting parts 18 and 18 are mounted on the left and right preliminary seedling mounting parts 18 and 18, both the left and right preliminary seedling mounting bases 24 and the left and right preliminary drawing markers 32 and 32 are easily stored, and the storage space of the machine is increased. It's narrow.

  In the above embodiment, the rice transplanting operation for attaching the heel marker 70 to the right line drawing marker 32 has been described. However, depending on the field conditions, the rice padding marker 70 may be attached to the left line drawing marker 32 to perform the rice transplanting operation in the same manner. It can also be done. In the above-described embodiment, an example in which the rod marker 70 is detachable from the left and right line drawing markers 32 and 32 has been shown. However, the left and right line drawing markers 32 and 32 are respectively provided with telescopic rod markers 70 and 70 like a fishing rod. It may be mounted and used in a state similar to that of FIG.

  The present invention can be applied to a seedling transplanter such as a riding rice transplanter.
