It can be switched to the state.

(Folding structure)
The seedling transplanting machine 1 has a configuration for reducing the left and right widths of the seedling planting unit 4 during transportation and storage. First, the structure which folds the right-and-left end part of the seedling mounting part 80 is demonstrated (refer FIGS. 21-25).

  A partition wall 81-4 that divides the third seedling mounting part 80-3 and the fourth seedling mounting part 80-4 from the left is divided into an inner part 81a and an outer part 81b, and the inner part 81a. Is integrally formed with the center seedling mounting portions 80-4 to 80-8, and the outer portion 81b is formed integrally with the three left outer seedling mounting portions 80-1, 80-2, 80-3. Yes. This partition wall 81-4 is formed higher than the other partition walls except the partition wall 81-9. Then, a single rotating shaft 121 is inserted through the cylindrical portions 120a, 120b,... Formed at the upper end portions of both the inner and outer portions 81a, 81b. The strip seedling mounting parts 80-1, 80-2, 80-3 are inverted inwardly, and the corresponding parts of the fourth to sixth seedling mounting parts 80-4, 80-5, 80-6 from the left side are reversed. They are folded so that they overlap. .. Are attached to the tops of the columns 117,... Provided on the fifth to seventh partition walls 81-5, 81-6, 81-7 from the left side. When the seedling mounting part is folded, the tops of the columns 117,... Provided on the partition walls 81-1, 81-2, 81-3 engage with the column receivers 122,.

  The partition wall 81-9 that divides the second seedling mounting part 80-9 and the third seedling mounting part 80-8 from the right is divided into an inner part 81a and an outer part 81b. The part 81a is formed integrally with the seedling mounting parts 80-4 to 80-8 in the central part, and the outer part 81b is formed integrally with the seedling mounting parts 80-9 and 80-10 of the right outer two stripes. The partition wall 81-9 is formed higher than the partition wall 81-4 with respect to the seedling mounting surface. Then, a single rotating shaft 121 is inserted through the cylindrical portions 120a, 120b,... Formed at the upper ends of both the inner and outer portions 81a, 81b. Fold the seedling mounting parts 80-9 and 80-10 in the upper direction and fold the part so as to overlap the third and fourth seedling mounting parts 80-7 and 80-8 from the right. ing. A concave support column 122 is fixed to the bottom surface of the leftmost partition wall 81-1, and the support column provided on the rightmost partition wall 81-11 when the right outer two seedlings are folded. The top of 117 engages with the column support 122. Further, the top of the support column 117 provided on the partition wall 81-8 and the top of the support column 117 provided on the partition wall 81-10 are connected by the auxiliary support column 123 to support the seedling mounting portions 80-9 and 80-10.

  Regarding the arrangement of the cylindrical parts, the cylindrical part 120a corresponding to the inner part 81a and the cylindrical part 120b corresponding to the outer part 81b are arranged in three upper and lower parts, and 120b, 120a, 120b from the top. , 120a, 120a, 120b are arranged in this order. Further, there is no gap between the upper two sets of cylindrical portions 120a and 120b, but a gap S is provided in the lowermost cylindrical portions 120a and 120b. This is due to the following reason. That is, since the L-shaped main body part 83b of the seedling receiving plate 83 has an acute angle in a side view, the seedling mounting parts 80-1, 80-2, 80-3 on the left outer three lines and the seedlings on the right outer two lines are placed. The seedlings 80-9 and 80-10 cannot be reversed at the same positions, and the seedlings are pushed up by the gap S along the inclination of the seedling mounting portion in order to avoid interference with the L-shaped main body portion 83b. This is for inverting the mounting portion.

  In FIG. 24, reference numeral 82 denotes the horizontal frame. −9, 80-10) in the vicinity of the boundary portion 82A and the outer portion 82B. The mounting member 88 is fixed to both left and right end portions of the central portion 82A, and the fixing member 124 is fixed to the inner end portion of the outer portion 82B so as to face the mounting member 88. The fixing member 124 is formed with a round hole 125 penetrating left and right, and the mounting member 88 is formed with a screw hole 126 on an extension line of the round hole 125. A fixing rod 127 threaded at the tip is inserted into the round hole 125 of the fixing member 124 from the outside, and the tip screw is screwed into the screw hole 126 of the mounting member 88, so The parts 80-1, 80-2, 80-3 (or 80-9, 80-10) are fixed to the seedling mounting parts 80-4 to 80-8 in the central part. A small-diameter portion 127a is formed at an appropriate position of the fixing rod 127. When the fixing rod 127 is pulled out from the screw hole 126 when folding the seedling mounting portion on the left and right outer portions, the tip of the knock pin 128 is engaged with the small-diameter portion 127a. Therefore, the fixing rod 127 is prevented from coming out any more. Since the outer wall surface of the small diameter portion 127a is tapered, the fixing rod 127 can be pushed in. 129 in the figure is a spring that urges the knock pin 128 toward the fixed rod.

  In FIG. 25, reference numeral 131 denotes a horizontal pipe provided on the upper surface of the back surface of the seedling mounting portion. , 80-3 (or 80-9, 80-10) near the boundary portion 131A and the outer portion 131B. A male screw member 132 is fitted on the inner end side of the hollow portion of the central portion 131A. A fixing rod 134 having a screw hole 133 formed at the tip is inserted into the horizontal pipe 131 from the outside, and the screw hole 133 is screwed into the male screw member 132, whereby the seedling mounting parts 80-1 on the left and right outer parts are 80-2, 80-3 (or 80-9, 80-10) is fixed to the seedling mounting part 80-4 to 80-8 in the central part. The mechanism for preventing the fixing bar 134 from dropping is the same as that of the fixing bar 127, and the knock pin 137 urged by the spring 136 is engaged with the small diameter portion 134a of the fixing bar 134.

  In the state where the left and right outer side seedling mounting portions are unfolded, the center seedling vertical feeding device 101A and the left and right outer side seedling vertical feeding device 101B are configured to be transmission-coupled (see FIG. 21). In other words, the roller drive shaft 103aA of the center seedling vertical feed device 101A is a drive clutch body having a drive arm 107 attached to its inner end via a ratchet mechanism 108 and a clutch pawl at its outer end. 140 is integrally attached. The drive clutch body 140 is engaged with a driven clutch body 141 attached to the outer roller drive shaft 103aB. The driven clutch body 141 is fitted to the roller drive shaft 103aB on the outer side so as to rotate integrally, is slidable in the axial direction, and is urged toward the shaft end side by a spring 142. Therefore, when the clutch bodies of the drive clutch body 140 and the driven clutch body 141 are connected, the driven clutch body 141 can escape even if both clutch claws collide with each other. Even if the body 141 is out of phase, the body 141 can be connected without difficulty and can be quickly bitten.

  As shown in FIG. 20, the seedling support frame 85 is provided with a horizontal frame 85b horizontally above the vertical frames 85a and 85a whose bases are fixed to the unit transmission portions 62-2 and 62-4. Rotating frames 85c and 85c are rotatably provided at the left and right ends of the rollers, and rollers 86 and 86 for supporting the seedling mounting portions 80-4 to 80-8 in the central portion at the upper ends of the vertical frames 85a and 85a. , And rollers 86 and 86 for supporting the left and right outer seedling mounting portions 80-1, 80-2, and 80-3 (or 80-9 and 80-10) at the distal ends of the rotating frames 85c and 85c. Is attached.

  As shown in FIG. 26, the roller 86 that supports the right and left outer seedling mounting portions has a roller shaft 86a fitted in the roller shaft hole of the rotating frame 85c so as to be slidable in the axial direction. The spring 86b that is loosely fitted is urged in a direction away from the rotating frame 85c, and is prevented by a split pin 86c inserted through the roller shaft 86a. A finger hook 86d is fixed to the end of the roller shaft 86a. When the finger is put on the finger hook 86 d and the roller shaft 86 a is pulled downward, the roller 86 is detached from the U-shaped recess of the upper rail 87.

  The connecting portion between the horizontal frame 85b and the rotating frame 85c is fitted to the shaft 85d on the side of the horizontal frame 85b so that the cylindrical portion 85e on the side of the rotating frame 85c is rotatable and slidable in the axial direction. A wavy cam 85f is formed integrally with the cylinder 85e, and the cylinder 85e is urged upward by a spring 85h so that a pin 85g inserted perpendicularly to the shaft 85d contacts the cam 85f. Yes. Normally, the pin 85g is engaged with the concave portion of the cam 85f, and the rotation frame 85c is stabilized in a state of facing the left and right sides. A stopper 85i is secured to the cam 85f so that the rotation frame 85c does not rotate to the seedling mounting side than the stable state.

  Further, the middle part of the seedling feed belt operation stopping wire 112 of the outer two strips is fixed at an appropriate position of the rotating frame 85c. For this reason, when the roller 86 supporting the right and left outer seedling mounting parts is detached from the U-shaped recess of the upper rail 87, the outer two strips of the seedling mounting part are folded and pulled by the wire 112, and the rotating frame 85c. Pivots backwards. At this time, since the pin 85g slides along the wavy cam 85f, the rotation frame 85c rotates smoothly.

  FIG. 27 is a diagram showing the structure of the split portion of the float support shaft. The float support shaft 211 includes a center portion 211A that supports the center float 210C and the mid floats 210M and 210M, and left and right end portions 211B and 211B that support the side floats 210S and 210S. The connecting members 260 and 261 are engaged with each other. Since the couplers 260 and 261 are formed long in the front-rear direction, the rotation of the central portion 211A by the operation of the planting depth lever 215 is reliably transmitted to the left and right end portions 211B and 211B. In addition, with this configuration, mud flows backward through the space portion 262 that is formed inside the couplers 260 and 261 and communicates with the front and rear, so that poor connection due to biting mud or the like does not occur.

  When the left and right end portions of the transmission case 60 are turned upward and bent, the folding portions 211B and 211B are also folded upward, and when the left and right end portions of the transmission case 60 are connected to the main body side, they are linked. Thus, the two parts 211A and 211B are connected. Thus, since it is not necessary to operate the float support shaft 211 at the time of folding and returning, the labor for reducing the lateral width of the paddy field work machine in general is reduced. When the float support shaft 211 is folded, the planting depth lever 215 is operated to the transport position, that is, the position where the floats 210 are lifted. At this time, since the couplers 260 and 261 are parallel to the rotation fulcrum shaft 170, the couplers 260 and 261 do not protrude downward and do not get in the way when the float support shaft 211 is folded.

(Lock arm)
The seedling planting unit 4 of the seedling transplanting machine is a side that is a planting main shaft in which the seedling mounting unit 80 and the planting device 200 are arranged in parallel corresponding to the planting strips and are commonly transmitted at the lower ends of the side by side seedling mounting units 80. The planting main shaft 70 is provided so that the planting device 200 at the outer end can be folded together with the planting main shaft 70.

  As shown in the enlarged side view of FIG. 28, the folding portion is formed with a regulating portion 221a for fixing the outer portion 70B of the planting main shaft 70 transmitted to the planting device 200 at the outer end in the unfolded state. The lock arm 221 is provided with a shaft support part 223 that pivotally supports a range A extending from the fixed position of the restricting part 221a to the release position, and the restricting part 221a and the shaft at the fixed position. The support part 223 is arranged at the front side position of the planting main shaft 70 while being divided up and down. Further, the lock arm 221 forms a gripping part 224 for swinging operation that is bent so as to protrude from the restricting part 221a to the front side of the machine body at a fixed position.

  Since the lock arm 221 having the above configuration is disposed facing the open space on the front side of the planting main shaft 70, the operator can swing the lock arm 221 to the fixed position without difficulty. In addition, the lock arm 221 having the above-described configuration can efficiently apply an operating force to the restricting portion 221a via the grip portion 224 adjacent to the restricting portion 221a, so that the lock arm 221 can be easily operated to the fixed position. Can do.

(Float adjuster)
As shown in FIG. 20, an enlarged side view of the main part is attached to the float 210, and a motor 241 as an actuator for changing the height is attached, and the height can be set with a dial. As shown in the side view of FIG. 29, a folding check switch 242 using a magnet switch is provided on the fixed side, and a magnet 243 is attached corresponding to the movable side. With this switch signal, it can be controlled to the deepest height position when folded so that it can be easily engaged when unfolded. As a result, there is no need for a depth lever, and it is easy to fold by reducing one operation. Become.

(Rotor device)
Here, a specific example of the entire configuration of the rotor device will be described again.
30 and 31 show a side view and a rear view of the leveling rotor device, respectively, and FIG. 32 shows a plan view of the main part of the rotor portion.

  In the rotor support structure, a beam member 266 whose upper ends are rotatably supported by members on both sides of the support frame of the seedling table, a support arm 267 fixed to both ends of the beam member 266, and a support arm 267 are connected to the support arm 267. A rotor support frame 268 that is movably attached is provided. A drive shaft 270 (270a, 270b) of the rotor 227 (227a, 227b) is attached to the lower end of the rotor support frame 268. Further, the vicinity of the lower end of the rotor support frame 268 is connected to a connecting member 271 that is rotatably attached to the transmission case.

  As shown in FIG. 32, the leveling rotor 227b at the center portion in front of the center float 255 in relation to the arrangement position with the floats 255 to 257 is the leveling rotor 227a at the side portion in front of the middle float 257 and the side float 256. It is arranged more forward. Therefore, the power to the drive shaft 270a of the rotor 227a is transmitted from the gear in the gear case 218 of the rear wheel via the universal joint 272 and the like. The power is transmitted from a pair of chains (not shown) in a pair of left and right chain cases 273 and 273 to which power is transmitted from the inner end of the vehicle body.

  Further, since the drive shaft 270b of the rotor 227b at the center of the machine body is only supported via a pair of left and right chain cases 273, 273, the pair of left and right chain cases 273, 273 are provided to reinforce the chain cases 273, 273. A reinforcing member 274 for bridging is provided. Further, the rotor 227b is suspended via a spring 278 by a pair of link members 276 and 277 whose upper ends are supported by the beam member 266.

  The pair of link members 276 and 277 have a first link member 276 whose one end is fixedly supported by the beam member 266 and a second link member 277 whose one end is rotatably connected to the other end of the first link member 276. The spring 278 is connected between the other end of the second link member 277 and a mounting piece 274a rotatably supported by the reinforcing member 274.

  The vertical positions of the rotors 227a and 227b can be adjusted by the vertical position adjustment lever 281 via the rotor support frame 268, the rotor support arm 267, and the beam member 266, but the beam member 266 and the vertical position adjustment lever 281 are locked. The section is as follows.

  The lower end portion of the vertical position adjusting lever 281 is connected by a link member having a “U” cross section and a rod penetrating the link member in the horizontal direction. The link member is integrally connected to the lever boss 282. The lever boss 282 includes an L-shaped plate in side view and a flat plate integrated with the L-shaped plate, and a shaft portion supported by a support frame is provided at the center of the L-shaped plate. The L-shaped plate is rotatably supported on the shaft portion. Further, the flat plate of the lever boss 282 is disposed so as to be in contact with a cylindrical portion of a roller having a protrusion 266a protruding from the beam member 266 as a rotation axis.

Therefore, when the vertical position adjusting lever 281 is rotated in the direction of arrow S in FIG. 31, the flat plate of the lever boss 282 pushes up the roller, so that the beam member 266 moves upward. At this time, the roller contacts the flat plate of the lever boss 282 while rotating, so that the operation load of the vertical adjustment lever 281 can be reduced, and since it is a rotating body, there is no wear and good operability can be secured. The lever boss 282 rotates up and down, and the lever boss 282 is locked so as to come into contact with the cylindrical portion of the roller having the protruding portion 266a as a rotation shaft. 31, the beam member 266 is moved upward. By the upward movement of the projecting portion 266a, the end portion of the first link member 276 opposite to the connecting portion with the beam member 266 is also rotated upward about the beam member 266. By rotating the first link member 276 upward, the rotor 227b can be lifted upward via the second link member 277 and the two springs 278. When the rotor 227b is moved upward, the rotor 227a is also simultaneously moved upward via the drive shaft 270b and the drive shaft 270a.
Since the rotor vertical position adjusting lever 281 is provided at substantially the center of the traveling portion, it is easy to balance left and right when the rotors 227a and 227b are moved up and down.

  Further, since the rotor support frame 268 moves upward by the rotation of the support arm 267, the rotors 227a and 227b can be moved to the storage position, that is, to the back side of the seedling table.

  In this embodiment, the rotor vertical position adjusting lever 281 is rotated in the direction of arrow S in FIG. 31 by rotating the rotor vertical positions adjusting lever 281 in the arrow S direction in FIG. It is set so that it can be increased up to 15 mm, and can be lowered up to 15 mm from the standard position by turning in the direction opposite to the arrow S direction in FIG.

  As shown in FIG. 31, a plurality of outer leveling rotors (second side leveling rotors) 227a1, 227a1 at both left and right ends are supported by rotor extension drive shafts (second side drive shafts) 270a1, 270a1 extending in the left-right direction. However, the rotor extension drive shafts 270a1, 270a1 are detachably attached to the rotor drive shafts (first side drive shafts) 270a, 270a on the more central side, and the rotor extension drive shafts 270a1, 270a1 are attached. The ground leveling rotors (second side leveling rotors) 227a1 and 227a1 attached to the head are removable.
