Further, as shown in FIGS. 43 and 44, the horizontal direction, which is a direction orthogonal to the front-rear direction K1, will be described as the machine width direction (width direction of the machine 2) K2. The direction from the central portion in the width direction of the transplanting machine 1 (airframe 2) toward the right portion or the left portion will be described as the outer side of the machine body (outer side in the width direction of the machine body). In other words, the outside of the machine is the direction K2 in the width direction of the machine and away from the center in the width direction of the transplanting machine 1 (body 2). The direction opposite to the outside of the aircraft will be described as the inside of the aircraft (inside in the width direction of the aircraft). In other words, the inside of the machine is the direction K2 in the width direction of the machine and is closer to the center in the width direction of the body 2.

As shown in FIGS. 43 to 45, the transplanting machine 1 has a machine body 2. A motor E1 is mounted on the rear part of the machine 2. The prime mover E1 may be an engine or a motor. Further, the airframe 2 has a mission case M1 to which the power from the motor E1 is transmitted. At the rear of the machine body 2, a steering handle 5 that is gripped by an operator when the transplanting machine 1 is walked is provided.

The transplanting machine 1 includes wheels that support the machine body 2 so as to be able to travel. The wheels include front wheels 3L and rear wheels 4L arranged on the left side of the airframe 2, and front wheels 3R and rear wheels 4R arranged on the right side of the airframe 2. The front wheels 3L and 3R are wheels that rotate freely, and the rear wheels 4L and 4R are drive wheels that are rotationally driven by transmitting power from the mission case M1. The wheels (front wheels 3L, 3R, rear wheels 4L, 4R) rotate in contact with the adjacent ridges (ridges) during the transplanting operation.

A front wheel support arm 6L is provided on the left side of the machine body 2. The upper portion of the front wheel support arm 6L is rotatably supported by the machine body 2 around a horizontal axis (an axis extending in the body width direction K2). The front wheel 3L is rotatably attached to the lower part of the front wheel support arm 6L. A front wheel support arm 6R is provided on the right side of the machine body 2. The upper portion of the front wheel support arm 6R is rotatably supported by the airframe 2 around a horizontal axis.

By simultaneously raising and lowering the front wheels 3L, 3R and the rear wheels 4L, 4R with respect to the aircraft 2, the aircraft 2 moves up and down with respect to the ground.
Specifically, when the front wheel support arms 6L and 6R are swung backward and the wheel supports 7L and 7R are swung forward, the distance between the front wheels 3L and 3R and the rear wheels 4L and 4R in the front-rear direction becomes smaller. Therefore, the wheels (front wheels 3L, 3R and rear wheels 4L, 4R) descend relative to the airframe 2, and the airframe 2 rises with respect to the ground (see FIG. 45). On the other hand, when the front wheel support arms 6L and 6R are swung forward and the wheel supports 7L and 7R are swung rearward, the distance between the front wheels 3L and 3R and the rear wheels 4L and 4R increases in the front-rear direction. Therefore, the wheels (front wheels 3L, 3R and rear wheels 4L, 4R) rise relatively with respect to the airframe 2, and the airframe 2 descends with respect to the ground (see FIG. 46).

The hydraulic cylinder (hereinafter referred to as "elevating cylinder") that swings and drives the front wheel support arms 6L, 6R and the wheel supports 7L, 7R is a wheel (not shown) together with an elevating control valve (not shown) that controls the operation of the elevating cylinder.

As shown in FIGS. 3 to 5, the seedling supply unit 12 is provided with an index body 98. The index body 98 indicates the inclination of the machine body 2 from the horizontal state. The index body 98 is arranged between the first seedling supply device 12L and the second seedling supply device 12R.
As shown in FIGS. 4 and 5, the index body 98 projects upward from the support frame body 22 (from the top plate 22a). Specifically, the index body 98 projects upward from the second elongated hole 22g formed in the top plate 22a of the support frame body 22. The second elongated hole 22g is formed in the central frame member 22M and extends in the machine width direction K2. The second slot 22g is arranged in front of the first slot 22f.

The index body 98 can swing along the second slot 22g on one side (left side) and the other side (right side) of the body width direction K2. Specifically, the index body 98 can swing in the first index direction (arrow L direction in FIG. 5) and the second index direction (arrow R direction in FIG. 5) with respect to the reference index position M. In FIGS. 4 and 5, the index body at the reference index position M is indicated by reference numeral 98M, the index body swinging in the first index direction L is indicated by reference numeral 98L, and the index body moved in the second index direction R is indicated by reference numeral 98L. It is shown by 98R. The reference index position M is located at the center of the second slot 22g in the machine width direction K2. The first index direction L is one side (left side) of the aircraft width direction K2 with respect to the reference index position M. The second index direction R is the other side (right side) of the aircraft width direction K2 with respect to the reference index position.

As shown in FIG. 5, a weight 99 is provided at the lower part of the index body 98. In the case of the present embodiment, the weight 99 is formed as an integral body with the index body 98, but the weight 99 may be attached to the lower part of the index body 98 as a separate member from the index body 98. Above the weight 99, a support shaft 79 that swingably supports the index body 98 is provided. The support shaft 79 is a shaft extending in the front-rear direction, and is supported by a shaft support member 112 provided below the support frame body 22. The shaft support member 112 is attached to the lower surface of the top plate 22a of the support frame body 22. The index body 98 faces in the vertical direction without being affected by the inclination of the ground or the inclination of the machine body 2 due to the vertical downward gravity acting on the weight 99. The index body 98 is located at the reference index position M when the machine body 2 is horizontal. When one side (left side) of the body 2 in the body width direction descends, the index body 98 tilts to the other side (right side) with respect to the body 2 and moves in the second index direction R. When the other side (right side) of the body 2 in the body width direction descends, the index body 98 tilts to one side (left side) with respect to the body 2 and moves in the first index direction L.

The first lever position 97L and the first index direction (left side) L are on the same side (left side) with respect to the straight line L1. The second lever position 97R and the second index direction (right side) R are on the same side (right side) with respect to the straight line L1.

As shown in FIGS. 3 to 5, a reference body 108 is provided in front of the index body 98. The reference body 108 is provided behind the lever 109. The lever 109 is a lever for adjusting the planting depth of seedlings by the planting tools 37L, 37R, 38L, 38R described later. The lever 109 can swing forward or backward.
The reference body 108 is provided to visually indicate to the operator that the index body 98 is in the reference position. The reference body 108 is attached to the machine body 2, and when the machine body 2 is tilted, the reference body 108 is tilted in the same direction as the machine body 2. As shown in FIG. 5, the lower portion of the reference body 108 is attached to the shaft support member 112 below the top plate 22a, and the upper portion projects upward from the top plate 22a.

The reference body 108 is configured as a plate material having an opening 108a whose upper edge is arcuate. A reference piece 108b is provided at the opening 108a. The reference piece 108b is provided at the center of the opening 108a in the machine width direction K2, and extends rearward and downward from the upper edge of the opening 108a. The opening 108a is provided at a position where it overlaps with the index body 98 when viewed from the rear. The reference piece 108b is in a position that overlaps with the index body 98 when viewed from the rear when the index body 98 is in the index reference position 98M.

As shown in FIG. 43, the chairs 13L and 13R are arranged rearward with respect to the leveling lever 97 and the index body 98. The leveling lever 97 is arranged behind the index body 98. Therefore, the horizontal adjustment lever 97 is arranged closer to the chairs 13L and 13R than the index body 98 in the front-rear direction.
The direction of the line of sight of the worker seated on the chairs 13L and 13R is the direction of arrow A1 shown in FIG. 4 (direction from the rear to the front). Therefore, when the worker seated on the chairs 13L and 13R faces forward, the horizontal adjustment lever 97 is visually recognized on the front side, and the index body 98 is visually recognized on the back side of the horizontal adjustment lever 97. Further, as shown in FIGS. 4 and 5, the reference body 108 is visually recognized behind the index body 98.

The chairs 13L and 13R can also be arranged in front of the horizontal adjustment lever 97 and the index body 98. In this case, the horizontal adjustment lever 97 is arranged in front of the index body 98. Further, the reference body 108 is arranged behind the index body 98. In this case, when the worker seated on the chairs 13L and 13R faces backward, the horizontal adjustment lever 97 is visually recognized on the front side, and the index body 98 is visually recognized on the back side of the horizontal adjustment lever 97. Further, the reference body 108 is visually recognized behind the index body 98.

Since the chairs 13L and 13R, the horizontal adjustment lever 97 and the index body 98 are in the above positional relationship, the operator can confirm the position of the index body 98 while sitting on the chairs 13L and 13R to confirm the position of the index body 98. It is possible to grasp the presence / absence of the inclination of 2 and the inclination direction and the direction in which the horizontal adjustment lever 97 should be operated.
Specifically, when the index body 98 overlaps with the reference piece 108b, it can be grasped that the machine body 2 is not tilted (horizontal). In this case, the horizontal adjustment lever 97 only needs to maintain the reference lever position 97M and does not need to be operated.

When the index body 98 is located on one side (left side) of the machine width direction K2 with respect to the reference piece 108b, the operator sets the horizontal adjustment lever 97 on one side of the machine width direction K2 (that is, the tilt direction of the index body 98). It can be understood that it should be swung in the same direction). In this case, since the machine body 2 is tilted downward to the right (the right side is lowered), the horizontal adjustment lever 97 is swung from the reference lever position 97M to the first lever position 97L, so that the machine body 2 is tilted downward. One side (left side) of K2 in the width direction of the machine can be lowered to make the machine 2 horizontal.

When the index body 98 is located on the other side (right side) of the machine width direction K2 with respect to the reference piece 108b, the operator sets the horizontal adjustment lever 97 to the other side of the machine width direction K2 (that is, the tilt direction of the index body 98). It can be understood that it should be swung in the same direction). In this case, since the aircraft 2 is in a state of being tilted downward to the left (the left side is descending), the horizontal adjustment lever 97 is swung from the reference lever position 97M to the second lever position 97R, so that the aircraft 2 is tilted. The other side (right side) of the aircraft width direction K2 can be lowered to make the aircraft 2 horizontal.

In this way, when the machine body 2 is tilted, the operator can return the machine body 2 to the horizontal position by operating the leveling adjustment lever 97 in the same direction as the tilting direction of the index body 98. Therefore, the operator can intuitively grasp the direction in which the horizontal adjustment lever 97 should be operated by looking at the index body 98 without being conscious of which direction the machine body 2 is tilted, and in the direction of eliminating the tilt. It can be operated correctly.

The cam 73 is provided on the free end side of the second rotation case 52, and rotates with the rotation of the second rotation case 52. The cam 73 has a pressing portion 73a having a large protrusion amount in the out-of-diameter direction and a pressing release portion 73b having a small protrusion amount in the out-of-diameter direction. The cam roller 74 abuts on the outer circumference of the cam 73. The upper part of the cam link 75 is rotatably supported by the first member 53L by a pivot axis 78 around a horizontal axis. A cam roller 74 is pivotally supported in the upper and lower parts of the cam link 75. One end of the opening / closing rod 76 is pivotally connected to the lower part of the cam link 75, and the other end of the opening / closing rod 76 is pivotally connected to the lower part of the first swing member 63.

From the front of the top dead center position to the front of the bottom dead center position of the elevating path of the first planting tool 37L, the cam roller 74 is in contact with the pressing release portion 73b, and the first planting tool 37L is closed. When the first planter 37L rushes into the field, the cam roller 74 rides on the pressing portion 73a. Then, the cam roller 74 is pressed by the cam 73, and the cam link 75 swings forward around the pivot 78. When the cam link 75 swings forward, the first component 58 is pulled via the opening / closing rod 76, and the first planting tool 37L opens.

The second planting tool 37R is also opened and closed by the second opening / closing mechanism 72R in the same operation.
As shown in FIG. 10, the first planting device 36L has a first interlocking mechanism 81L that opens and closes the third planting tool 38L in conjunction with the first opening / closing mechanism 72L. The second planting device 36R has a second interlocking mechanism 81R that opens and closes the fourth planting tool 38R in conjunction with the second opening / closing mechanism 72R. Since the first interlocking mechanism 81L and the second interlocking mechanism 81R have the same configuration, the first interlocking mechanism 81L will be described, and the description of the second interlocking mechanism 81R will be omitted.

As shown in FIG. 10, the first interlocking mechanism 81L has an interlocking link 82, a connecting member 83, and a connecting rod 84. The upper part of the interlocking link 82 is rotatably supported by a second member 54 of the first support 41L by a pivot axis 85 around a horizontal axis. The pivot 85 is provided concentrically with the pivot 78. The lower front portion of the interlocking link 82 is connected to the cam link 75 by a connecting member 83. As a result, the interlocking link 82 swings integrally with the cam link 75. One end of the connecting rod 84 is pivotally connected to the lower part of the interlocking link 82. The other end of the connecting rod 84 is pivotally connected to a first swinging member 63 that swingably supports the first component 58 of the third planting tool 38L.

In the above-mentioned first opening / closing mechanism 72L, the interlocking link 82 swings in conjunction with the swinging of the cam link 75 back and forth, so that the third planting tool 38L opens / closes via the connecting rod 84. In the same operation as this, the fourth planting tool 38R opens and closes in conjunction with the opening / closing operation of the second planting tool 37R by the second interlocking mechanism 81R.
As shown in FIG. 8, the transplanting machine 1 includes a guide member for guiding the seedlings supplied from the first seedling supply device 12L and the second seedling supply device 12R of the seedling supply unit 12 to the planting tool. The guide member includes a first relay guide 87L and a second relay guide 87R.

The first planting device 36L is provided with a first relay guide 87L for guiding seedlings to the first planting tool 37L and the third planting tool 38L. Further, the second planting device 36R is provided with a second relay guide 87R for guiding the seedlings to the second planting tool 37R and the fourth planting tool 38R. The first relay guide 87L is provided below the first position X1 and the second position X2 (see FIG. 10) of the first seedling supply device 12L. The second relay guide 87R is provided below the first position X1 and the second position X2 of the second seedling supply device 12R. In other words, the first relay guide 87L and the second relay guide 87R are located below the seedling supply cups 14A and 14B at the first position X1 and the second position X2.

The first relay guide 87L includes a first guide 88L for guiding the seedlings to the first planting tool 37L and a third guide 89L for guiding the seedlings to the third planting tool 38L. The second relay guide 87R includes a second guide 88R that guides the seedlings to the second planting tool 37R, and a fourth guide 89R that guides the seedlings to the fourth planting tool 38R. The first guide 88L, the second guide 88R, the third guide 89L, and the fourth guide 89R are formed in a quadrangular pyramid shape (or conical shape) having a shape tapered downward and having an open upper part and a lower part. There is.

As shown in FIG. 9, the first guide 88L is attached to the first member 53L of the first support 41L, and the third guide 89L is attached to the second member 54L of the first support 41L. The second guide 88R is attached to the first member 53R of the second support 41R, and the fourth guide 89R is attached to the second member 54R of the second support 41R.
The seedlings that fell from the seedling supply cups 14A and 14B at the first position X1 and the second position X2 are passed through the first relay guide 87L and the second relay guide 87R, and the first planting tool 37L and the second planting tool 37R. , 3rd planting tool 38L, 4th planting tool 38R. That is, the space between the seedling supply cups 14A and 14B in the vertical direction and the first relay guide 87L and the second relay guide 87R is the seedling delivery section 77L, 77R from the seedling supply section 12 to the transplant section 11 (FIG. 8). See).

Here, the first planting tool 37L, the third planting tool 38L, and the first relay guide 87L move up and down at the same time, and the second planting tool 37R, the fourth planting tool 38R, and the second relay guide 87R move up and down at the same time. .. Then, the seedlings are delivered from the seedling supply unit 12 to the transplanting unit 11 when the planting tool and the guide member are raised. Therefore, the delivery section 77L is a space between the seedling supply cups 14A and 14B and the first relay guide 87L when the first planting tool 37L, the third planting tool 38L, and the first relay guide 87L are raised (FIG. 8). Further, the delivery portion 77R is a space between the seedling supply cups 14A and 14B and the second relay guide 87R when the second planting tool 37R, the fourth planting tool 38R, and the second relay guide 87R are raised. (See the left part of FIG. 8).

The planting tool on the left side (1st planting tool 37L, 3rd planting tool 38L, 1st relay guide 87L) and the planting tool on the right side (2nd planting tool 37R, 4th planting tool 38R). , 2nd relay guide 87R), but for convenience of explanation, FIG. 8 shows a state in which both the planting tool on the left side and the planting tool on the right side are raised.
FIG. 12 is a diagram showing a configuration of a power transmission mechanism 111 that transmits power from the prime mover E1 to the transplanting unit 11 and the seedling supply unit 12. The power from the prime mover E1 is transmitted to the transmission case M1 and then transmitted to the clutch housing C1 via the transmission shaft, the gear mechanism, and the like. A power branch portion including a gear mechanism or the like is housed in the clutch housing C1, and the power transmitted to the clutch housing C1 is branched into one and the other and output. The power output to one side is transmitted to the drive shaft 31 (see FIGS. 6 and 7) of the transplant portion 11. The power output to the other side is transmitted to the seedling supply unit 12.

A power cutoff mechanism 130 is provided in the power transmission path for transmitting power from the clutch housing C1 to the seedling supply unit 12. The power cutoff mechanism 130 can allow or cut off the transmission of power to the seedling supply unit 12 by the power transmission mechanism 111.
The power cutoff mechanism 130 includes a first transmission shaft 131, a second transmission shaft 132, and a relay unit 133. Power from the prime mover E1 is transmitted to the first transmission shaft 131 via the transmission case M1 and the clutch housing C1. The second transmission shaft 132 transmits the power output from the clutch housing C1 to the seedling supply unit 12.

As shown in FIGS. 12 and 13, the first transmission shaft 131 is arranged at the lower part of the power cutoff mechanism 130, and the second transmission shaft 132 is arranged at the upper part of the power cutoff mechanism 130. A relay unit 133 is arranged between the first transmission shaft 131 and the second transmission shaft 132. As shown in FIGS. 14 and 15, the relay unit 133 has a first disk 134, a second disk 135, an annular plate 136, and an urging member 137.

The first disk 134 is fixed to the upper part of the first transmission shaft 131. The second disk 135 is fixed to the lower part of the second transmission shaft 132. The upper surface of the first disk 134 and the lower surface of the second disk 135 are arranged so as to face each other. The diameter of the first disk 134 is larger than the diameter of the second disk 135. The first disk 134 is formed with a first hole 134a and a second hole 134b. The first hole 134a is arranged inside (the side closer to the center of the disk) than the second hole 134b. A third hole 135a is formed in the second disk 135. The first hole 134a and the third hole 135a are arranged at positions where they overlap in the vertical direction.

The annular plate 136 is arranged above the second disk 135. The inner diameter of the annular plate 136 is smaller than the outer diameter of the second disk 135, and the outer diameter is larger than the outer diameter of the second disk 135. A fourth hole 136a is formed in the annular plate 136. The fourth hole 136a is arranged at a position overlapping the second hole 134b in the vertical direction.
The urging member 137 is composed of a spring 137a and a sphere 137b. Sphere 137b
Is fixed to the upper end of the spring 137a. The diameter of the sphere 137b is larger than the diameter of the third hole 135a. The lower end of the spring 137a is fitted into the first hole 134a of the first disk 134. Only the upper part of the sphere 137b is fitted in the third hole 135a of the second disk 135. The spring 137a urges the sphere 137b upward so as to press it against the third hole 135a.

The annular plate 136 and the first disk 134 are fixed by screwing the bolt BL and the nut NT. The shaft portion of the bolt BL is inserted from the fourth hole 136a of the annular plate 136 into the second hole 134b of the first disk 134, and the nut NL is screwed into the shaft portion. As a result, the annular plate 136 and the first disk 134 are relatively non-rotatably fixed. The second disk 135 is sandwiched between the annular plate 136 and the first disk 134.

When the force that hinders the operation is not applied to the seedling supply unit 12, the force that hinders the rotation does not act on the second disk 135. In this case, when the first disk 134 rotates with the rotation of the first transmission shaft 131, the rotational force of the first disk 134 is transmitted to the second disk 135 via the urging member 137. At this time, since the upper portion of the sphere 137b of the urging member 137 is in a state of being fitted in the third hole 135a, the sphere 137b rotates around the axis of the first transmission shaft 131 to rotate to the second disk 135. Power is transmitted. As a result, the second disk 135 rotates, and the second transmission shaft 132 rotates. That is, the rotation of the first transmission shaft 131 is transmitted to the second transmission shaft 132. In other words, the power cutoff mechanism 130 allows the transmission of power.

When a force that hinders the operation is applied to the seedling supply unit 12, a force that hinders the rotation acts on the second disk 135. In this case, when the first disk 134 rotates with the rotation of the first transmission shaft 131, the urging member 137 rotates around the axis of the first transmission shaft 131, but the rotation of the second disk 135 is hindered. Therefore, the sphere 137b is separated from the third hole 135a. Therefore, the rotational force of the first disk 134 is not transmitted to the second disk 135. That is, the first disk 134 idles with respect to the second disk 135. As a result, the rotation of the first transmission shaft 131 is not transmitted to the second transmission shaft 132. In other words, the power cutoff mechanism 130 cuts off the transmission of power.

When the power cutoff mechanism 130 allows the transmission of power, the power output from the clutch housing C1 to the other is transmitted to the seedling supply unit 12 via the power cutoff mechanism 130. Specifically, the power output from the clutch housing C1 to the other is transmitted to the third sprocket 124 via the power cutoff mechanism 130 to rotate the third sprocket 124. The third sprocket 124 is arranged below the drive sprocket 18 of the second seedling supply device 12R, and is connected to the drive sprocket 18. Therefore, the drive sprocket 18 of the second seedling supply device 12R rotates with the rotation of the third sprocket 124. As a result, the driven sprocket 19 and the transfer chain 20 of the second seedling supply device 12R rotate.

A fourth sprocket 125 is arranged below the drive sprocket 18 of the first seedling supply device 12L. A chain 126 is wound around the third sprocket 124 and the fourth sprocket 125. A first gear 127 is arranged above the fourth sprocket 125. The first gear 127 is connected to the fourth sprocket 125 and rotates with the rotation of the fourth sprocket 125. The second gear 128 meshes with the first gear 127. The second gear 128 is arranged below the drive sprocket 18 of the first seedling supply device 12L, and is connected to the drive sprocket 18.

When the third sprocket 124 is rotated by the power output from the clutch housing C1 to the other, this rotation is transmitted by the chain 126 to rotate the fourth sprocket 125. When the fourth sprocket 125 rotates, the first gear 127 and the second gear 128 rotate, and the drive sprocket 18 of the first seedling supply device 12L rotates. As a result, the driven sprocket 19 and the transfer chain 20 of the first seedling supply device 12L rotate.

When the power cutoff mechanism 130 cuts off the transmission of power, the power output from the clutch housing C1 to the other is not transmitted to the seedling supply unit 12. Specifically, since the power output from the clutch housing C1 to the other is not transmitted to the third sprocket 124, the operation of the transfer mechanism of the first seedling supply device 12L and the second seedling supply device 12R is stopped.
By providing the power cutoff mechanism 130 described above, for example, when an operator accidentally pinches a finger between the transfer chain 20 of the seedling supply unit 12 and the support frame 22, the seedling supply unit 12 has a finger. On the other hand, when a force that hinders the operation is applied, the transmission of the power from the prime mover E1 to the seedling supply unit 12 is cut off. As a result, the operation of the seedling supply unit 12 (the operation of the transfer mechanism such as the rotation of the transfer chain 20) is stopped, so that the operator can be prevented from being injured or the seedling supply unit 12 can be prevented from being damaged.

As shown in FIGS. 9 and 16 to 18, the transplanting machine 1 has a tube for guiding water to a guide member (first guide 88L, second guide 88R, third guide 89L, fourth guide 89R) (hereinafter, "" It is equipped with 94,95 (also referred to as "irrigation tube").

It can swing upward or downward independently of the adjusting levers 140L and 140R.

By swinging the adjusting levers 140L and 140R upward or downward, the shaft body 175 can be rotated around the axis.
When the adjustment lever 140L is rotated upward (in the direction of arrow D1), the shaft body 175 rotates clockwise in the left side view, and the first support member 171L (swing arm 174 and support arm 173) is the machine body 2. It swings downward (in the direction of arrow E1). As a result, the soil covering pressure by the left soil covering ring (first grounding member 161L, third grounding member 162L) increases.

When the adjustment lever 140L is rotated downward (in the direction of arrow D2), the shaft body 175 rotates counterclockwise in the left side view, and the first support member 171L (swing arm 174 and support arm 173) becomes a machine body. It swings upward (in the direction of arrow E2) with respect to 2. As a result, the soil covering pressure by the left soil covering ring (first grounding member 161L, third grounding member 162L) becomes low.
Similarly, when the adjusting lever 140R is rotated upward, the soil covering pressure by the right soil covering ring (second ground contact member 161R, fourth ground contact member 162R) increases. Further, when the adjusting lever 140R is rotated downward, the soil covering pressure by the right soil covering ring (second ground contact member 161R, fourth ground contact member 162R) becomes low.

As shown in FIG. 19, the ridge height detecting member 180 includes a first support member 171L and a second support member 171L arranged in the central portion in the width direction of the machine body among a plurality of support members (first to fourth support members). It is connected to the member 171R. The third support member 172L and the fourth support member 172R arranged on the outer side of the machine body are not connected to the ridge height detection member 180.
The ridge height detecting member 180 has a detecting unit 181 and an interlocking unit 182.

The detection unit 181 has a first vertical member 181L, a second vertical member 181R, and a horizontal member 181H. One end (lower end) of the first vertical member 181L is connected to the support arm 173 of the first support member 171L and extends upward from the support arm 173. One end (lower end) of the second vertical member 181R is connected to the support arm 173 of the second support member 171R, and extends upward from the support arm 173. The horizontal member 181H connects the other end (upper end) of the first vertical member 181L and the other end (upper end) of the second vertical member 181R. The detection unit 181 shall rise or fall based on the swing of the first support member 171L and the second support member 171R that follow the change in the height of the ridges on which the first grounding member 161L and the second grounding member 161R touch the ground. Detects the height of the ridges.

The interlocking portion 182 interlocks the swing of the first support member 171L and the second support member 171R with the raising and lowering of the machine body 2 by the machine body raising and lowering mechanism. One end of the interlocking unit 182 is connected to the detection unit 181 (horizontal member 181H), and the other end is connected to the spool of the elevating control valve described above via an interlocking member such as a cable. The interlocking unit 182 moves the spool of the elevating control valve in response to the ascent or descent of the detection unit 181. By moving the spool of the elevating control valve, the rod of the elevating cylinder operates to raise and lower the machine body 2 with respect to the wheels. Specifically, when the detection unit 181 is raised, the machine body 2 is raised with respect to the wheels, and when the detection unit 181 is lowered, the machine body 2 is lowered with respect to the wheels. As a result, the machine body 2 can be raised and lowered in accordance with the change in the height of the ridges.

The ridge height detecting member 180 connects a plurality of support members (first support member 171L and second support member 171R), and detects at least the ridge height based on the swing of the plurality of support members. The ridge height can be detected in consideration of the heights of the two ridges. This makes it possible to accurately detect the average ridge height in consideration of the variation in the height of the plurality of ridges.
As shown in FIG. 19, the support members 170 adjacent to each other in the width direction of the machine body are connected by the connecting member 177. Specifically, the connecting member 177 connects the first support member 171L and the third support member 172L, and connects the second support member 171R and the fourth support member 172R. The connecting member 177 is connected to the support members 170 (first support member 171L and third support member 172L, second support member 171R and fourth support member 172R) adjacent to each other in the width direction of the machine body by bolts or the like. The shape of the connecting member 177 is not limited to the flat plate-shaped member as shown in the figure.

As shown in FIGS. 43 to 45 and the like, the transplanting machine 1 includes a cover 190. The cover 190 is attached to the front portion of the machine body 2.
As shown in FIGS. 21 to 24, the cover 190 has a front plate portion 190F and side plate portions 190L and 190R. The front plate portion 190F and the side plate portions 190L and 190R are integrally configured. The front plate portion 190F and the side plate portions 190L and 190R are preferably integrally molded, but may be combined after being molded as separate members.

The front plate portion 190F is inclined so as to move forward from the upper side to the lower side. The front plate portion 190F has a central portion 190FM, a left portion 190FL, and a right portion 190FR. The central portion 190FM extends in the aircraft width direction K2. The left portion 190FL is curved so as to move backward from the left end of the central portion 190FM toward the left (outside the fuselage). The right portion 190FR is curved so as to move backward from the right end of the central portion 190FM toward the right (outside the fuselage). The central portion 190FM is provided with an extension portion 190a extending in a cylindrical shape toward the rear. An opening 190b is formed in a region surrounded by the extending portion 190a. The front and rear of the front plate portion 190F communicate with each other through the opening 190b. Since the opening 190b is formed in the region surrounded by the extending portion 190a, it is possible to suppress the decrease in strength of the cover 190 due to the opening 190b.

The extending portion 190a is formed in a square cylinder shape, and has an upper wall portion 190aU, a lower wall portion 190aD, a left wall portion 190aL, and a right wall portion 190aR. The upper wall portion 190aU shifts downward toward the rear. The lower wall portion 190aD extends horizontally toward the rear. The left wall portion 190aL shifts to the right as it goes backward. The right wall portion 190aR shifts to the left toward the rear. As a result, the area of the opening 190b (the area seen from the front) gradually increases toward the front.

The side plate portions 190L and 190R have bulging portions 190La and 190Ra. The bulging portion 190La is provided at the lower part of the side plate portion 190L. The bulging portion 190Ra is provided at the lower part of the side plate portion 190R. The bulging portion 190La bulges toward the left. The bulging portion 190Ra bulges toward the right. As a result, the bulging portions 190La and 190R swell in the direction away from the machine body 2 (outside the machine body) with the cover 190 attached to the machine body 2.

The cover 190 has a mounting portion 191 for mounting on the machine body 2. The mounting portion 191 has a first through hole 191a, a second through hole 191b, and a locking portion 191c. The first through hole 191a is provided in the left portion 190FL and the right portion 190FR of the front plate portion 190F, respectively. The second through hole 191b is provided in the side plate portion 190L and the side plate portion 190R, respectively. The second through hole 191b is provided in the upper part of the side plate portions 190L and 190R (above the bulging portions 190La and 190R). The locking portion 191c is provided on each of the bulging portion 190La and the bulging portion 190Ra, respectively. The locking portion 191c is formed by cutting out the lower edge of the bulging portion 190La and the lower edge of the bulging portion 190Ra upward.

As shown in FIGS. 25 to 27, the attachment portion 191 of the cover 190 is attached to the first attachment member 192, the second attachment member 193, and the third attachment member 194 provided on the machine body 2. Although FIG. 26 shows the mounting structure of the mounting portion 191 on the left side of the cover 190, the mounting structure of the mounting portion 191 on the right side of the cover 190 is also the same.
As shown in FIGS. 25 to 27, the first through hole 191a of the mounting portion 191 is mounted on the first mounting member 192. As shown in FIGS. 16 and 17, the first mounting member 192 is mounted on the front portion of the first connecting member 50L and the second connecting member 50R. The first mounting member 192 is provided with a screw hole. By inserting the bolt BL1 into the first through hole 191a of the cover 190 and screwing the bolt BL1 into the screw hole of the first mounting member 192, the mounting portion 191 becomes the first mounting member 192 in the first through hole 191a. It is attached.

As shown in FIGS. 25 to 27, the second through hole 191b of the mounting portion 191 is mounted with respect to the second mounting member 193. The second mounting member 193 is mounted on the front portion of the left frame member 22L and the front portion of the right frame member 22R of the support frame body 22, respectively. The second mounting member 193 is provided with a screw hole. By inserting the bolt BL2 into the second through hole 191b of the cover 190 and screwing the bolt BL2 into the screw hole of the second mounting member 193, the mounting portion 191 becomes the second mounting member 193 in the second through hole 191b. It is attached.

The locking portion 191c of the mounting portion 191 is mounted with respect to the third mounting member 194. As shown in FIGS. 25 and 26, the third mounting member 194 is mounted on the columns 17L and 17R. As shown in FIGS. 43 and 45, the columns 17L and 17R are erected in front of the decks 10L and 10R. The third mounting member 194 is provided with a protruding portion 194a that protrudes toward the outside of the machine body. The protrusion 194a is composed of, for example, a screw head. By locking the locking portion 191c of the cover 190 to the protruding portion 194a, the mounting portion 191 is mounted to the third mounting member 194 in the locking portion 191c.

As described above, the cover 190 is attached to the machine body 2 by attaching the attachment portion 191 to the first attachment member 192, the second attachment member 193, and the third attachment member 194.
As shown in FIGS. 27 and 43, the upper edge of the cover 190 is attached to the machine body 2 and is along the peripheral edge of the support frame body 22. Specifically, the upper edge of the front plate portion 190F is along the front surface of the support frame body 22 (front plate 22d of the front frame member 22F). The upper edge of the side plate portion 190L is along the left side surface of the support frame body 22 (the left side plate 22b of the left frame member 22L). The upper edge of the side plate portion 190R is along the right side surface of the support frame body 22 (the right side plate 22c of the right frame member 22R).

As shown by virtual lines in FIGS. 19 and 20, when the cover 190 is attached to the machine body 2, at least the front and side of the seedling delivery section 77L, 77R from the seedling supply section 12 to the transplant section 11 cover. Specifically, the front plate portion 190F covers the front of the delivery portions 77L and 77R, and the side plate portions 190L and 190R cover the sides of the delivery portions 77L and 77R. Thereby, the cover 190 functions as a windshield from the front and the side. Therefore, the seedlings can be smoothly and surely delivered from the seedling supply unit 12 to the transplanting unit 11 without being affected by strong winds, gusts, and the like.

As shown in FIG. 19, the cover 190 has a relay guide (first relay guide 87L and second relay guide 87L and second) from the lower ends of the seedling supply cups 14A and 14B in both the raised state and the lowered state of the planting tool and the relay guide. It covers the range up to the upper end of the relay guide 87R). Further, the cover 190 covers most of the planting tools in the ascending position (first planting tool 37R and third planting tool 38R in FIG. 19), and the planting tool in the descending position (second in FIG. 19). The planting tool 37L and the fourth planting tool 38L) are not covered.

As shown by a virtual line in FIG. 17, the irrigation tubes 94 and 95 are housed in the bulging portions 190La and 190Ra. Specifically, the bulging portions 190La and 190Ra accommodate the irrigation tubes 94 and 95 located on the outer side of the machine body of the first connecting material (side frame) 50L and the second connecting material (side frame) 50R. Will be done.
As shown by a virtual line in FIG. 17, the cover 190 covers the upper part of the front frame material 29, the first connecting material (side frame) 50L, and the second connecting material (side frame) 50R in a plan view U. It is provided in a character shape. The bulges 190La, 190Ra cover the sides of the irrigation tubes 94, 95. Further, the front plate portion 190F covers the front of the irrigation tubes 94 and 95.

Specifically, the bulging portions 190La, 190Ra cover the sides of the irrigation tubes 94, 95 arranged along the first connecting material (side frame) 50L and the second connecting material (side frame) 50R. The front plate portion 190F covers the front of the irrigation tubes 94 and 95 arranged along the front frame material 29. This prevents other objects from coming into contact with or being caught by the irrigation tubes 94, 95 and causing the irrigation tubes 94, 95 to come off.

As shown in FIGS. 43 and 45, the trailing edge of the cover 190 is located in front of the chairs 13L and 13R when the cover 190 is attached to the machine body 2. Further, as shown in FIG. 44, the bulging portions 190La and 190Ra of the cover 190 bulge to the left and right (outside the machine body) with respect to the machine body 2. As a result, a space is formed between the bulging portions 190La, 190Ra and the machine body 2, and the rear part of the space is opened. Therefore, the worker seated on the chairs 13L and 13R can visually recognize the portion covered with the cover 190 (delivery portion 77L, 77R, etc.) from the rear of the bulging portions 190La, 190Ra.

The cover 190 is made of a transparent or translucent material. The cover 190 has a fixed shape. The cover 190 is made of, for example, a resin (hard resin) such as acrylic resin, polycarbonate, polyethylene terephthalate, polypropylene, ABS resin, polyvinyl chloride, glass, or the like. However, the materials constituting the cover 190 are not limited to these. Since the cover 190 is transparent or translucent, the portion covered by the cover 190 (delivery portion 77L, 77R, etc.) can be visually recognized from the front or side of the transplanting machine 1. Therefore, the state of the portion covered by the cover 190 can be confirmed without removing the cover 190.

As shown in FIGS. 20, 27, and 43, adjustment levers 140L and 140R are inserted forward through the opening 190b formed in the front plate portion 190F. A setting plate 201 describing the relationship between the position of the lever and the soil covering pressure is arranged near the rear of the opening 190b. The setting plate 201 is formed with an elongated hole extending in the vertical direction, and the adjusting levers 140L and 140R are inserted into the elongated hole. The adjusting levers 140L and 140R can swing along the elongated hole, and the soil covering pressure can be set by fixing the adjusting levers 140L and 140R at a plurality of positions along the elongated hole.

The circumference of the adjusting levers 140L and 140R is surrounded by a square cylindrical extending portion 190a, and the front end portions of the adjusting levers 140L and 140R do not protrude from the cover 190. Therefore, it is possible to prevent unintended contact with the adjusting levers 140L and 140R.
Next, the support structures of the chairs 13L and 13R will be described with reference to FIGS. 28, 29, and 45. Although FIGS. 28, 29, and 45 show the support structure of the first chair 13L, the support structure of the second chair 13R is also the same.

The chairs 13L and 13R are supported by the wheel supports 7L and 7R. Specifically, the first chair 13L is supported by the wheel support 7L. The second chair 13R is supported by the wheel support 7R.
The wheel supports 7L and 7R each have a transmission case 100. The power of the prime mover E1 is output from the output shaft 102 via the transmission mechanism in the transmission case M1 and transmitted to the axles of the rear wheels 4L and 4R via the transmission mechanism (gear mechanism, transmission shaft, etc.) in the transmission case 100. Will be done. As a result, the rear wheels 4L and 4R are driven by the power of the prime mover E1. The transmission case 100 is provided so as to be swingable with respect to the machine body 2. Specifically, the transmission case 100 is provided so as to be swingable around the horizontal axis (around the axis of the output shaft 102) with respect to the machine body 2.

The chairs 13L and 13R are supported by the transmission case 100 by the support mechanism 103. As shown in FIGS. 28 and 29, the support mechanism 103 includes a support column 104, a bracket 105, a support shaft 106, and a connecting member 107.
The support columns 104 are arranged on the outer side of the rear wheels 4L and 4R. The support column 104 is composed of a tubular pipe such as a cylinder or a hexagonal cylinder, for example. The lower part of the column 104 is connected to the bracket 105. As shown in FIG. 30, a connecting rod 30 extending downward from the lower surface of the seat portion 13a of the chairs 13L and 13R is fitted in the upper portion of the support column 104.

The connecting rod 30 is composed of a cylindrical or hexagonal tubular pipe. The connecting rod 30 is formed to have a thickness that allows outer fitting or inner fitting with respect to the support column 104. As can be seen from FIGS. 30 and 43, the connecting rod 30 fitted into the support column 104 is provided at a position deviated from the center of the seat portion 13a of the chairs 13L and 13R. Specifically, the connecting rod 30 extends downward from a position shifted to the right from the center of the seat portion 13a of the chair 13L in the width direction. Further, the connecting rod 30 extends downward from a position shifted to the left from the center in the width direction of the seat portion 13a of the chair 13R.

As shown in FIGS. 43 to 45, the support column 104 includes a support column 104L arranged on one side (left side) of the machine body 2 and a support column 104R arranged on the other side (right side) of the machine body 2. .. The connecting rod 30 of the chair 13L is fitted into the support column 104L. The connecting rod 30 of the chair 13R is fitted into the support column 104R.
The chairs 13L and 13R are mounted on the side of the seedling supply unit 12 by inserting the connecting rod 30 into the support column 104 from above. In other words, the support column 104 constitutes a mounting portion (hereinafter referred to as "first mounting portion 104") for mounting the chairs 13L and 13R on the side of the seedling supply portion 12. The chairs 13L and 13R can be removed from the first mounting portion 104 by pulling out the connecting rod 30 from the columns 104L and 104R. That is, the chairs 13L and 13R are removable from the first mounting portion 104. Further, the orientation of the chairs 13L and 13R when mounted on the first mounting portion 104 can be changed around the central axis of the support column 104.

In this specification, unless otherwise specified, the chairs 13L and 13R are mounted on the first mounting portion 104 (see FIG. 43 (solid line), FIGS. 44, 45) as a reference. The positional relationship between the chairs 13L and 13R and other components is explained.
As shown in FIGS. 28 and 29, the bracket 105 has a first side plate 105a, a second side plate 105b, and a connecting portion 105c. The first side plate 105a is arranged on the inside of the machine body of the support column 104, and is located between the rear wheels 4L, 4R and the support column 104. The second side plate 105b is arranged on the outer side of the machine body of the support column 104 and faces the first side plate 105a. The connecting portion 105c extends in the width direction of the machine body, and connects the upper portion of the first side plate 105a and the upper portion of the second side plate 105b, and the rear portion of the first side plate 105a and the rear portion of the second side plate 105b.

The bracket 105 is pivotally supported by the transmission case 100. Specifically, the bracket 105 is pivotally supported by the first pivot shaft 141 with respect to the pivot plate 100d provided on the transmission shaft case 100c of the transmission case 100. The pivot plate 100d extends upward from the transmission case 100. The pivot plate 100d includes a first pivot plate 100d1 and a second pivot plate 100d2 arranged so as to face each other. The first pivot plate 100d1 is arranged on the side of the second side plate 105b toward the inside of the aircraft. The second pivot plate 100d2 is arranged on the outer side of the machine body of the first side plate 105a. The first pivot shaft 141 extends in the width direction of the machine body and penetrates the first side plate 105a, the second side plate 105b, the first pivot plate 100d1, and the second pivot plate 100d2. As a result, the bracket 105 can swing around the first pivot shaft 141 with respect to the transmission case 100.

The support shaft 106 projects laterally from the machine body 2. One end side (inside the machine body side) of the support shaft 106 is fixed to the machine body 2 and extends from the machine body 2 toward the outside of the machine body. The support shaft 106 is arranged above and behind the output shaft 102.
The connecting member 107 has an inner plate 107a, an outer plate 107b, and an upper plate 107c. The inner plate 107a is arranged on the inside of the machine body of the support column 104, and is located between the support column 104 and the rear wheels 4L and 4R. The outer plate 107b is arranged on the outer side of the machine body of the support column 104 and faces the inner plate 107a. The upper plate 107c connects the upper portion of the inner plate 107a and the upper portion of the outer plate 107b in front of the support column 104.

One end side (front side) of the connecting member 107 is pivotally supported on the other end side (outside side of the machine body) of the support shaft 106. As a result, the connecting member 107 can swing upward or downward around the support shaft 106. The other end side (rear side) of the connecting member 107 is pivotally supported by the bracket 105. Specifically, the other end side of the connecting member 107 is pivotally supported by the second pivot shaft 142 with respect to the bracket 105. The other end side of the connecting member 107 is above the transmission case 100 and is arranged above the pivot plate 100d. The other end side of the inner plate 107a is arranged on the outer side of the first side plate 105a of the bracket 105. The other end side of the outer plate 107b is arranged on the inside of the machine body of the second side plate 105b of the bracket 105. A tubular body 105d is fixed to the bracket 105, and the second pivot shaft 142 is rotatably supported with respect to the tubular body 105d. The second pivot shaft 142 extends in the width direction of the machine body and penetrates the inner plate 107a, the outer plate 107b, and the cylinder body 105d. As a result, the bracket 105 can swing upward or downward around the second pivot shaft 142 with respect to the other end side of the connecting member 107. The second pivot shaft 142 is located above the first pivot shaft 141. The support column 104, the bracket 105, and the connecting member 107 form a chair support that supports the chairs 13L and 13R with respect to the support shaft 106.

The bracket 105, the connecting member 107, the output shaft 102, the support shaft 106, the first pivot shaft 141, and the second pivot shaft 142 constitute a four-section link mechanism. When the transmission case 100 swings upward or downward around the axis of the output shaft 102, the bracket 105 moves upward or downward. Therefore, when the transmission case 100 swings around the axis of the output shaft 102, the support column 104 to which the bracket 105 is attached can be raised and lowered without tilting. Therefore, the posture of the worker seated on the chairs 13L and 13R supported by the support column 104 is not impaired. Further, the weight of the worker sitting on the chairs 13L and 13R can be distributed and supported by the first pivot shaft 141 and the second pivot shaft 142 and the like.

The transmission case 100 slides along the output shaft 102 and can move in the width direction of the machine body. The connecting member 107 slides along the support shaft 106 and can move in the width direction of the machine body. Since the transmission case 100 and the connecting member 107 are connected via the bracket 105, they can be integrally moved in the width direction of the machine body (outside the machine body or inside the machine body). When the transmission case 100 and the connecting member 107 move to the outside of the machine body, the chairs 13L and 13R and the rear wheels 4L and 4R move to the outside of the machine body and separate from the machine body 2. When the transmission case 100 and the connecting member 107 move toward the inside of the machine, the chairs 13L and 13R and the rear wheels 4L and 4R move toward the inside of the machine and approach the machine 2. That is, the transmission case 100, the output shaft 102, the connecting member 107, and the support shaft 106 constitute a moving mechanism that causes the chairs 13L, 13R and the rear wheels 4L, 4R to approach or separate from the machine body 2.

Due to the movement mechanism, the chairs 13L, 13R and the rear wheels 4L, 4R are on one side in the width direction of the machine and approaching the machine 2, and on one side in the width direction of the machine and with respect to the body 2. It becomes possible to move in the direction of separation.
FIG. 42 shows a state in which the chairs 13L, 13R and the rear wheels 4L, 4R are brought close to the machine body 2 (hereinafter, referred to as “approaching state”). FIG. 43 shows a state in which the chairs 13L, 13R and the rear wheels 4L, 4R are separated from the machine body 2 (hereinafter, referred to as “separation state”).

Further, the first mounting portion 104 to which the chairs 13L and 13R are mounted by the moving mechanism is also one side in the body width direction and one side in the body width direction and one side in the body width direction.
