A vertically movable mechanism that is rotatably provided and has a large number of seedling accommodating bodies having the guide disk as a bottom plate at a predetermined interval on the outer periphery of the turntable and is operated by the progress of the transplanter on the main body frame. There is a configuration in which a transplanter that receives the transplanted seedlings that are dropped from the drop opening via the and that transfers the transplanted seedlings to the ridge transplantation portion is vertically movable.

(Problems to be Solved by the Invention) The transplanter having the above-mentioned configuration is preferable in that transplanted seedlings can be transplanted at predetermined intervals with respect to the ridge transplanting portion. If the machine hits the end of the ridge and the transplanter cannot proceed further with the device inserted in the ridge transplantation part, the vertical movement mechanism is not activated. Device cannot be lifted upward from the transplant site, so the transplanter can be moved to the next transplant site,
There is a problem that you cannot turn around. Further, since the transplanter is moved up and down with the movement of the transplanter, this transplanter is also moved up and down in conjunction with the movement of the ridge at a place other than the transplant portion, which is a safety problem. In addition, a complicated control means is required to control the rotation of the turntable so that the transplanted seedlings in the seedling container can be accurately dropped from the drop opening of the guide disk.
When the seedling container containing the transplanted seedlings is moved to the drop opening of this guide disk, a complicated control means is required to move the transplanter just below this drop opening, and its structure is complicated. There is a problem of becoming.

Therefore, the present invention has been made in view of such a problem, so that the transplanter can be easily pulled up and stopped upward from the transplantation portion of the ridge as necessary, and the turntable can be accurately moved to a predetermined position.

When the lever is remotely switched, the drive shaft power switching mechanism is switched, power transmission to the link mechanism is released, the operation of the link mechanism is stopped, and the brake mechanism is switched to the brake ring of the turntable. The braking action is released. In addition, as described above, the power transmission to the link mechanism is released, the braking action to the turntable is released, and the pulling action by the spring causes the transplanter to automatically move upward from the ridge transplant portion via the link mechanism. It is lifted up and stopped, so the transplanter can be safely moved.

When the operating lever is further switched, the power is transmitted to the drive shaft by the switching operation of the power switching mechanism, and the brake ring of the turntable is braked again by the switching operation of the brake mechanism. Then, when the link mechanism is raised and rotated, the transplanter is raised toward one of the seedling container of the turntable, and the turntable is rotated by a predetermined angle by the link mechanism during the raising. At this time, since the turntable is braked by the brake mechanism via the brake ring, one seedling container having the transplanted seedlings is accurately stopped at the transplanted seedling supply section. Further, the transplanted seedlings dropped from the seedling container of the transplanted seedling supply section are automatically received by the link mechanism in the transplanter which has been raised to the transplanted seedling supply section in advance.

Further, when the turntable is rotated by a predetermined angle as described above by the upward rotation of the link mechanism, the empty seedling container into which the transplanted seedlings have been dropped and supplied in the previous step is moved to the outside of the transplanted seedling supply unit, Prepare for receiving transplanted seedlings.

Next, when the link mechanism is rotated downward, the transplanter receiving the transplanted seedlings is lowered, and the transplanted seedlings in the transplanter are vertically transplanted to the ridge transplanting portion. Further, the transplantation device is pulled up from the transplantation portion of the ridge by the upward rotation of the link mechanism, and is operated again as described above to receive the transplanted seedling in the transplantation device.

When the adjusting rod 54 is moved back and forth against the coil spring 56, the left and right swing arms 49 are vertically rotated about the axle 47, and the left and right guide rollers 52 are covered with the multi-film F. The left and right side surface portions D of the formed ridge A are engaged at optimum positions.

And in the case of transplanting work on a flat surface, the operation handle
21 is rotated backward around the horizontal shaft 20 against the spring 25, and the locking pin 23 of the operation handle 21 is inserted into the locking hole 13 at the center of the support frame 12. This allows
The operation handle 21 is biased forward by the biasing action of the spring 25, and the locking pin 23 thereof is inserted and retained in the locking hole 13, but the locking pin 23 is formed smaller than the size of the locking hole 13. Therefore, the locking pin 23 is swingably inserted and held in the locking hole 13.

Next, when the engine 4 is driven, the mission 5 is transmitted through the output shaft 6, the pulley 7, the endless belt 10 and the pulley 9.
The input shaft 8 is rotated, and the left and right traveling wheels 3 are rotationally driven in the traveling direction via the axle 2 by the power from the mission 5, and the output shaft 76, the pulley 77, the endless belt 78, the pulley 73, The drive shaft 71 is rotationally driven via the rotary shaft 74, the sprocket 72, the endless chain 75, and the sprocket 70.

Then, by the rotational driving of the left and right traveling wheels 3, the transplanter advances along the ridge A while straddling the ridge A. At this time,
Since the left and right guide rollers 52 are pressed against the left and right side surfaces D of the ridge A to rotate while rotating, the running direction control action of the left and right guide rollers 52 determines the running direction of the front wheel 48. Moves along the ridge A, and the front wheels 48 rotate while rotating through the mulch film F.
The surface of the transplanted part C is prepared while it is flattened. Also, when the transplanting machine is moving along the ridge A, the left and right running wheels 3 move up and down when the mulch film F is pushed up and down by the soil mass that holds the multi-film F in the groove B. The traveling frame 1 on which the wheels 3 are mounted is
It is rotatably connected to the planted frame 30 via a bearing body 29 and a rotation center shaft 28, and a locking pin 23 is swingably supported in a locking hole 13 of the support frame 12. As a result, the planting frame 30 is rocked and inclined independently of the planting frame 30 in the left-right direction with respect to the horizontal plane of the traveling direction.
30 is the ridge A without being tilted in conjunction with the tilting motion.
With respect to the transplanted part C, the process continues in a horizontal state.

Further, when the drive shaft 71 is rotationally driven in the clockwise direction in FIG. 4 as the transplantation machine progresses, the rotating piece 138 integrated with the drive shaft 71 makes the first support via the support shaft 137. The operating piece 135 supported by the piece 132 is rotated clockwise while pushing it against the coil spring 147, and the support shaft 139 at the lower end of the operating piece 135 is the first interlocking piece. By pushing 140, the first interlocking piece 140 is rotated upward about the first interlocking shaft 148 supported by the second supporting piece 133. Further, by the upward rotation of the first interlocking piece 140, the transplanter 127 having the thermal perforation body 128 is directed to the seedling receiving position of the turntable 102 via the L-shaped interlocking piece 150 and the second interlocking piece 152. While gradually rising vertically, this first interlocking piece 14
The push pin 178 of 0 pushes the tip of the vertical moving piece 21 upward, the vertical moving piece 121 is gradually rotated upward about the mounting shaft 122, and the operating rod 118 pushes upward. While being moved, the release rod 116 is rotated upward about the support shaft 115 by the operating rod 118. Also, the shutter 109 of the seedling container 104 of the turntable 102 in which the pushing piece 117 of the release piece 116 is moved to the transplant seedling supply section 113 in the front part of the release port 111a by the upward rotation of the release piece 116.
And the shutter 109 is automatically rotated inward of the release port 111a by the restoring force of the spring 110, and the drop port 107 of the seedling container 104 is opened.

The ratchet 185 is reversely rotated with respect to 100, and the ratchet 185 is backwardly locked by the next feed gear of the ratchet gear 101 to prepare for the next rotation of the turntable 102. In this case, the brake ring 103, which is integrated with the ratchet gear 101, serves as a pair of brake pieces 199, 20 of the brake mechanism 209.
Since it is sandwiched between the inner and outer parts via the brake shoe 201 between the upper part of 0, during the backward movement for switching the ratchet 185, the ratchet gear 1 is used by the ratchet 185.
01 is not rotated, and during the feeding operation of the ratchet gear 101, the ratchet gear 101 can be accurately rotated by a predetermined angle without being rotated by inertial force.

Next, the rotation of the drive shaft 71 causes the rotation piece 138 to rotate in the clockwise direction in FIG. 4 from the lower portion of the drive shaft 71, and the rotation piece 138 moves the support shaft 137. The operation piece 135 supported by the first support piece 132 is rotated while being pulled upward against the coil spring 147, and the support shaft 139 at the lower end of the operation piece 135 is the first interlocking piece. Tow 140

A transplant hole I is formed by thermal contact with the widthwise intermediate portion of the mulch film F covering the ridge A by the heat perforation body 128 connected to the transplant device 127 in the transplant portion C of the portion. That is, the thermal drilling body 12
Since 8 and the transplanter 127 are arranged in the front and back through the first support rod 187 and the second support rod 188 which are parallel to each other in the vertical direction, the thermal perforation body 128 and the transplanter 127 are simultaneously lowered, A transplant hole I is preliminarily formed in the middle portion in the width direction of the mulch film F at the lowered position of the transplanter 127 by the heat perforation body 128 during the pre-transplantation process, and therefore the seedling plant 162 of the transplanter 127 is accurately formed. Then, a transplant hole J is formed by piercing the exposed soil in the transplant hole I. Further, when the seedling plant 162 is stuck in the soil, the tropical pore body 128 is supported by the transplant hole I, and the first support rod 187 and the second support rod 188 which are vertically parallel to each other are respectively supported by the support shafts 158, 158.

The actuating piece 135 is pushed downward via 137, the first interlocking piece 140 is rotated upward as described above, and the L-shaped interlocking piece 150 and the second interlocking piece 152 are used for transplantation. The vessel 127 and the thermal perforation body 128 are pulled upward from the transplant portion C of the ridge A. Further, the actuating piece 135 is rotated downward so that the transplanter 127 is pulled up above the transplanted seedling G in the transplanting part C, and the restoring force of the coil spring 173 causes the seedling planting body 162 of the transplanter 127.
A pair of planting pieces 163, 164 in the gradual rotation inwardly about the support shaft 172, and the open guide passage 165 of the seedling planting body 162 is closed again, thus the transplanter 127 and the value. Along with the upward movement of the perforated body 128, the guide passage 165 of the seedling plant 162 of the transplanter 127 is gradually closed and formed to prepare for receiving and guiding the soil block H having the transplanted seedling G for the next transplanting operation.

Further, when the transplant device 127 and the thermal perforation body 128 are pulled up to a predetermined position, the second interlocking piece 152 rotates the L-shaped interlocking piece 150 about the first interlocking shaft 148, and at the same time, the L-shaped interlocking piece is interlocked. The piece 150 causes the third support piece 134 to move to the third fixed shaft.
It is rotated around 131, and the interlocking rod 180 is pulled by the upper operating piece 179. When the interlocking rod 180 is pulled, the rotating arm 182 moves the rotating shaft via the bearing body 183.
The ratchet gear 185 is rotated forward with respect to 100, the ratchet gear 101 is rotated by the ratchet 185, and the turntable 102 integrated with the ratchet gear 101 is rotated.
Next seedling container 10 having 02 transplanted seedling G soil block H of 02
One of the four is moved to the transplant seedling supply section 113 in the front part of the release port 11a, and the shutter 109 of this seedling container 104 is a guide ring.
Instead of 111, it is supported by the pushing piece 117 in a state in which the drop port 107 is closed, and prepares for the operation of the operating rod 118 as described above.

Also, the turntable 102 is rotated to release the opening 1 as described above.
Seedling container 104 having soil block H of transplanted seedling G in 13
When the empty seedling container 104 that has dropped the soil block H of the transplanted seedling G at the front part in the rotating direction of the seedling container 104 approaches the other end of the guide ring 111 at the release port 111a, The shutter 109 of the empty seedling container 104 engages with the guide roller 125, and as the turntable 102 rotates, the shutter 109 resists the spring 110 by the guide roller 125, and the shutter 109 is centered on the mounting shaft 108.
The shutter 109 is rotated toward the drop opening 107 of the 104.
Is engaged with the guide ring 111 instead of the guide roller 125 in a state where the drop port 107 is closed, and prepares for supplying the soil block H of the transplanted seedling G into the empty seedling container 104. Then, the transplanter 127 is moved up again just below the seedling container 104 located in the transplanted seedling supply section 113, and the operating rod 118 is pushed by the pushing pin 178 via the vertical moving piece 121 as described above. The shutter 109 is rotated to open the drop port 107, and the soil block H of the transplanted seedling G is dropped and received in the transplanter 127 in the seedling container 104.

In this way, the transplanter heats the transplantation holes J at predetermined intervals in the transplantation part B of the ridge A while advancing along the ridges A, and the transplanter 127 sequentially inserts the soil blocks into the respective transplantation holes J. The transplanted seedling G of H is transplanted vertically.

Next, in a state where the transplanter is advanced along the ridge A and the transplanter 127 and the thermal perforation body 128 are lowered to the transplant part C of the ridge A, the guide rollers 52 on the left and right of the tip end are located at the front part in the advancing direction, for example. When a situation occurs such as hitting the terminal end of a ridge or a ridge, the transplant device 127 and the thermal perforation body 128 are not moved by the upward rotation of the link mechanism 126.
When it is necessary to pull the ridge A upward from the transplantation portion C of the ridge A, the operating lever 95 provided on the support handle 27 of the transplanter is provided.
If the wire 94 of the power switching mechanism 97 and the wire 206 of the brake mechanism 209 are towed at substantially the same time when the wire 94 of the power switching mechanism 97 is towed, the switching lever 91 will support the projection 92. The switching body is pulled and rotated with the shaft 93 as a fulcrum, and the switching body is switched by the interlocking shaft 90 of the switching lever 91.
85 is a coil spring 96 along the sliding shaft portion 83 of the drive shaft 71.
The clutch pawl 84 of the switching body 85 disengages from the clutch pawl 89 of the sprocket 70, and the power transmission from the sprocket 70 to the drive shaft 71 is released, so that the implanter 127 is slid inward in the axial direction. Also, the operation of the link mechanism 126 for raising and lowering the thermal perforation body 128 is stopped. When the wire 206 of the brake mechanism 209 is pulled, the other brake piece 100 is rotated against the coil spring 204 with respect to the one brake piece 199 with the horizontal shaft 198 as a fulcrum, and the other brake piece 199 is rotated. Brake shoe 2 on top of piece 100
01 is separated from brake ring 103 and brake ring 1
03 is no longer held and therefore the turntable 102
The braking action of is released. Further, the power transmission to the drive shaft 71 and the braking action to the turntable 102 are released so that they are released, and the locking pin of the operating piece 15 is released.
The operation piece 135 is lowered by the restoring force of the coil spring 147 stretched between the 145 and the locking pin 146 of the first interlocking piece 140, and the first interlocking piece 140 moves the first interlocking shaft 148.
The first support hangs on the second support piece 133 and the third support piece 134, which are rotated upward about
Through the interlocking piece 140, the L-shaped interlocking piece 35, and the second interlocking piece 152, the transplant device 127 and the thermal perforation body 128 are automatically pulled up from the transplant part C of the ridge A.

Next, for transplanting work on a sloping ground, the running wheels 3 on the left and right of the transplanting machine straddle the ridge A covered with the multi-film F.
Is arranged in the groove B of the ridge A, the entire transplanter is installed in a state of being inclined in the left-right direction with respect to the inclination direction of the sloping ground, that is, the traveling direction.

Therefore, when the operation handle 21 is rotated rearward about the horizontal shaft 20 against the spring 25 and the operation handle 21 is rotated in the direction opposite to the inclination direction of the transplanter, the bracket 18 and the rotation shaft 16 are rotated. Interlocking rod 31 via the operation handle
In addition to being rotated in the rotation direction of 21, the interlocking rod 31 makes the planting frame 30 independent of the traveling frame 1 via the bearing body 29 and tilts around the rotation center axis 28 of the traveling frame 1. It is interlocked and rotated in the opposite direction. Then, the planting frame 30 is pivotally displaced horizontally, and the operation handle
21 is rotated forward of the support frame 12 side around the horizontal shaft 20 together with the restoring force of the spring 25, and the locking pin 23 of this operation handle 21 is inserted into the locking holes 13 at predetermined left and right positions of the support frame 12. To do. As a result, the angle of the planted frame 30 is independently adjusted with respect to the traveling frame 1 to correct the traveling posture, and the spring 25 urges the operation handle.
21 is biased forward, and its locking pin 23 is inserted and retained in the locking hole 13, but since this locking pin 23 is formed smaller than the size of the locking hole 13, the locking pin 23 Is swingably inserted and retained in the locking hole 13. Therefore, the transplanting machine runs while swinging the traveling frame 1 depending on the condition of the groove portion B, but the planting frame 30 travels in a horizontal state with respect to the transplanting portion B of the ridge A. Therefore, as in the case of the transplanting work on the flat land, the transplanted seedling G is transferred to the transplanted part C.
It is transplanted vertically in the transplantation hole J of.
