The front end of the lifting cylinder 17 is attached to the frame 4, and the protruding end of the piston rod 18 that protrudes obliquely upward from this is connected to the lower end of the arm 19 that is integral with the upper link 16. When it appears, the elevating frame 15 is moved up and down while maintaining the same posture.
[0007]
The seedling planting device 3 is configured as follows. A gear box 20 is attached to the rear bottom of the lifting frame 15. Five implanted frames 21 extend from the gear box 20 and sleeves (not shown) laterally protruding therefrom at substantially equal intervals. Rotating cases 22 are attached to both sides of the rear portion of each implantation frame 21 and are rotated counterclockwise when viewed from the right (FIG. 1) by the power of the engine 9. A pair of planting ridges 23 are attached to the respective rotating cases 22, and the planetary gears therein turn around while maintaining substantially the same posture by the above rotation, so that seedlings are transplanted alternately. In addition, the right and left planting ridges 23 are arranged at intervals of 30 cm to 33 cm, and transplant seedlings to 10 rows in one stroke.
[0008]
The seedling receiving plate 24 having ten seedling openings arranged side by side is fixed to the planting frame 21 so that the tip portions of the pair of planting ridges 23 pass alternately through the seedling openings in the middle of the descending turn. It has become. A support column 25 extends obliquely forward from the front part of the left and right planting frames 21, and a seedling mounting table 26 is supported by the protruding end and the front part of the seedling receiving plate 24 so as to move left and right. A seedling stage 26 is connected to a laterally moving rod 27 (FIG. 4) that protrudes left and right from the gear box 20, and is configured to reciprocate left and right by the power of the engine 9.
[0009]
The seedling mount 26 is inclined forward and is divided into ten sections by nine partition walls between the left and right side walls. Then, the mat-like group seedlings are placed on the respective sections so that the rear end protrudes from the seedling receiving plate 24. When the rear end of the population seedlings come on seedlings Tokuchi the lateral movement of the seedling mounting table 26, a share component seedlings are taken away at the distal end of Uekomi杆23. The cut off seedlings are lowered with the planting pot 23 and transplanted so as to be inserted into the mud surface of the paddy field at the lower end of the turning. That is, when the above operation is repeated while the traveling vehicle body 1 is moved forward, seedlings are transplanted into 10 strips in one stroke, and between the transplanted seedlings, the strips 28-1, 28-2,... -9 (FIG. 2) is formed.
[0010]
The left and right front wheels 7 are disposed on the extensions of the striations 28-3 and 28-7.

In addition, the auxiliary | assistant wheel of the rear-wheel 8 can be arrange | positioned on extension of the stripes 28-1 and 28-9.
[0011]
A plurality of floats 29 are arranged side by side, and can slide on the mud surface when the traveling vehicle body 1 moves forward.
A belt conveyor 30 for feeding out the group seedlings can be arranged in each section of the seedling stage 26, and the driving and folding of the seedling stage 26 can be configured as follows.
The seedling mount 26 is divided in the middle of the second partition wall from the outside, the left and right partition plates 31A, 31B extend upward, and the upper ends of the partition plates 26 are connected by the rotation shaft 32 (FIG. 4). Therefore, the two sections at the lateral ends of the seedling mounting table 26 can be folded as shown in FIG. The ends of the sleeve protruding left and right from the gear box 20 are divided and connected by a shaft in the front-rear direction. When the implantation frame 21 at the outer end is rotated approximately 90 degrees around the axis, it is bent upward as shown in FIG.
[0012]
The drive shaft 33 is provided horizontally in the lower abdomen of the seedling mount 26 (FIG. 5).
The drive shaft 33 includes a central drive shaft 33A, drive shafts 33B on both sides thereof, and drive shafts 33C on both ends. The drive shaft 33C is disposed below the outer end and the inner compartment. When the drive shaft 33B and the drive shaft 33C are connected by a claw-type shaft joint 34 under the partition plates 31A and 31B, and the lateral end (the above two sections) of the seedling mount 26 is folded as described above (FIG. 3). ) When the drive shaft 33C is automatically separated from the drive shaft 33B and returned to its original position (FIG. 2), both are automatically connected. When the drive shaft 33A and the drive shaft 33B are connected by the claw clutch 35 under the third section from the outside, and the wire 37A is loosened by the operation of the hook clutch lever 36A (FIGS. 1 and 2), the left and right claws bite and the claws When the clutch 35 is “on” and the rotation of the drive shaft 33A reaches the drive shaft 33B, and the wire 37A is stretched, the left and right claws are separated, and the claw clutch 35 is “disconnected” and reaches the drive shaft 33B. The above transmission is cut off.
[0013]
A shaft 38 (FIG. 6) protruding laterally from the gear box 20 is rotated counterclockwise in FIG. When the pair of arms 39 are fixed to this and the seedling stage 26 comes to the right end by the above-described reciprocation, the roller 39a of the right arm 39 pushes the lever 40 integral with the drive shaft 33A in the clockwise direction, and turns to the left end. When it comes, the roller 39a of the left arm 39 pushes the lever 40 in the same direction.
[0014]
When the roller 39a is separated from the lever 40, it is pulled back to the original position by a spring (not shown). The rotation of the drive shaft 33A is transmitted to the drive shafts 33B and 33C by the pawl clutch 35 and the shaft coupling 34 as described above.
The partition walls 41 are odd-numbered from the lateral end of the seedling mount 26 and are formed into a mountain shape by bending a thin plate (FIG. 6). Under each partition wall 41, a lever 42 is fixed to the drive shafts 33A and 33C. Five belt drive shafts 43 having aligned axes are disposed under a pair of sections, and a drive roller 44 is fixed in each section. A claw wheel 45 is fixed to the belt drive shaft 43, and a rotating plate 46 is attached to the side thereof. The middle of the link 47 is pivotally attached to the end of the lever 42 and is turned clockwise by a spring 48, and the rear end 47 a abuts the pin 46 a of the rotation plate 46. Therefore, when the drive shafts 33A and 33C rotate in the clockwise direction, the rotating plate 46 rotates in the same direction, and the claw 49 rotates the claw wheel 45 (and the belt drive shaft 43) in the same direction. When the drive shafts 33A and 33C rotate in the reverse direction, the rotating plate 46 is pulled by the spring 50 and returns to the original position. At this time, the claw 49 slides on the claw wheel 45 and the belt drive shaft 43 stays at that position (not reversed).
[0015]
A driven roller 51 (FIG. 4) is arranged in each section, and the belt 52 is wound around the driving roller 44 and the belt conveyor 30.
That is, when the seedling mounting table 26 comes to the right (or left) end and the planting basket 23 cuts out the left (or right) end of the group seedling protruding on the seedling receiving plate 24, the belt conveyor 30 is It operates to feed out the group seedlings on the seedling receiving plate 24 side.
[0016]
The three links 47 in the center are made as follows. The operation plate 53 is attached to the lower abdomen of the seedling mount 26 with a shaft 54, and when the wire 37B is stretched, the pin 53a pushes down the front portion of the link 47 by rotating clockwise. Then, the link 47 rotates counterclockwise around the tip of the lever 42 against the spring 48, and the rear end 47a rises and separates from the pin 46a. When the wire 37B is loosened, the link 47 rotates in the reverse direction and the rear end 47a is connected to the pin 46a. Three saddle clutch levers 36B are arranged side by side behind the seat 11 inside the pair of saddle clutch levers 36A (FIG. 1), and the respective wires 37B are stretched or loosened by the operation.
[0017]
Therefore, when the end of transplantation of one field approaches and the number of seedling transplants in one stroke is adjusted, the right end hook clutch lever 36A is operated to stretch the wire 37A. Then, the right claw clutch 35 is “disengaged”, and the right end and the belt conveyor 30 inside thereof become inoperable (in accordance with this, the right end or the two sets of implantation rods 23 can be stopped). Further, when the adjacent saddle clutch lever 36B is operated to stretch the wire 37B, the two adjacent conveyors 30 do not operate. That is, the number of seedlings can be reduced by two and the number of transplants can be adjusted.
[0018]
Conventionally, all the belt conveyors 30 are driven with the configuration shown in FIG. Therefore, when the lateral end of the seedling mounting base 26 is folded as shown in FIG. 3, the rear ends of the wires 37A at both ends come upward, and the middle part projects sideways, which may cause the rear wheel 8B to wrap around the projecting part. there were. Compared with this, according to said structure, since the rear end of the wire 37B does not move in folding of the horizontal end of the seedling mounting stand 26, said fear was eliminated.
[0019]
The fertilizer applicator 2 is configured as follows. A total of ten grooving devices 55 are attached to the float 29, and as the traveling vehicle body 1 moves forward, ten fertilizer grooves are formed in the mud surface next to each shoot to be transplanted.

A brush 67 is provided with a hair tip contacting the rotor 66. The front wall of the guide tube 63 is opened and covered with a cover 68 that swings around a lower axis.
Accordingly, the granular (or powdery) fertilizer in the fertilizer tank 62 is fed out by the rotation of the respective rotors 66 and flows into the discharge pipe 60. Then, it is sent by the blown air, passes through the inside of each tube 64, reaches the grooving device 55, and is sprayed into the fertilization groove formed.
[0021]
A damper 69 is provided between the arm 56a of the support tube 56 and the arm 59a extending from the air chamber 59 so that the support rod 58 slides in the support tube 56 so that the air chamber 69, the fertilizer tank 62, and the like can be lifted and lowered easily. (Figs. 8 and 9).
A horizontal shaft 70 is rotatably attached to the rear portion of the support plate 57 (FIGS. 8 and 9), and is swung by an operation of a lever 71 fixed thereto. An arm 56b extends rearward from the upper part of the support tube 56, and a pin 72 is provided at the rear part thereof. A fixing plate 73 extending downward from the horizontal shaft 70 is disposed in front of the pin 72. When the fertilizer tank 62 or the like is lowered and the lever 71 is rotated counterclockwise in FIG. So that the fertilizer tank 62 and the like are kept in that position.
[0022]
A fixing rod 74 whose upper end is rotatably attached to the horizontal shaft 70 is disposed after the pin 72. When the fixing rod 74 is pulled clockwise by the spring 75 (FIG. 9) and the fertilizer tank 62 is raised, the lower front locking groove 74a is engaged with the pin 72, and the fertilizer tank 62 and the like are raised. To keep on. In this state, when the cover 68 is rotated to the position of the chain line in FIG. 7 and the brush 67 is removed, the fertilizer remaining in the fertilizer tank 62 can be easily taken out.
[0023]
When the switch 76 is attached to the right arm 56 b and the locking groove 73 a is engaged with the pin 72, the switch 76 is turned “OFF”. The control device outputs to the buzzer as follows in response to the input of “ON” and “OFF”. (1) When the switch 76 is “ON”, the main clutch is “engaged”, and the transmission is not “neutral” (when the traveling vehicle body 1 is in progress and the fertilizer tank 62 is raised), a buzzer sounds. . (2) When the switch 76 is “ON” and the main clutch is “disengaged” or the transmission is “neutral” (when the fertilizer tank 62 is raised but the traveling vehicle body 1 is stopped), a buzzer sounds. Absent. (3) When the switch 76 is “OFF” (when the fertilizer tank 62 is lowered), the buzzer does not sound.
[0024]
According to the above configuration, when the traveling vehicle body 1 is moved when the locking groove 73a of the fixing plate 73 is disengaged from the pin 72 (when not locked), a buzzer sounds and safety is improved. .
