And the implants 14a and 14b are damaged.
It is difficult to receive. An embodiment of the present invention will be described in detail with reference to the drawings. Reference numeral 1 denotes a passenger towing vehicle, which has a steering frame 5 protruding from a front upper portion of a vehicle body 4 having a front wheel 2.2 for steering and a rear wheel 3.3 for allowing a steering handle 6 to be supported thereon.
An engine 7 is mounted on the vehicle body behind the steering handle 6.
A control seat 9 is provided on the upper part of the vehicle. Reference numeral 10 denotes a transmission support case for the rear wheels 3.3. Reference numeral 11 denotes a transplantation device, which is mounted on the rear part of the vehicle body 4 and is located rearward at a predetermined left and right distance from the main transmission case 12a located at the front and the main transmission case 12a. On the upper part of the transplantation transmission case 12 composed of three sub-transmission cases 12b to be provided, a seedling mounting table 13 which is inclined so that the front becomes upper is supported so as to reciprocate left and right. At the rear end of the auxiliary transmission case 12b, a rotating case 15 on which the implanters 14a and 14b are mounted is mounted on a shaft.
2, a center leveling float 16 and left and right side leveling floats 17, 17 are mounted so that the front part can move up and down. Reference numeral 18 denotes an elevating link mechanism, which is an upper link rod 1.
8a and the base side of the lower link rod 18b are pivotally connected to the vehicle body 4, and the rear ends of both links are pivotally connected by a vertical link 18c. The transplant transmission case 12 is connected to the vertical link 18c via a support shaft 19. The upper link 18a is provided so as to be movable up and down by a hydraulic cylinder device 20. 2
A hydraulic switching valve 1 is mounted on the main transmission case 12a so as to be interposed between the integral projection frame 22 and the center leveling float 16, and is switched by the vertical movement of the float 16. Thus, the hydraulic cylinder device 20 is operated to automatically set the ground contact pressure of the center leveling float 16 to a range suitable for transplantation. The hydraulic switching valve 21 can be arbitrarily switched by an elevating operation lever 23 attached to the side of the control seat 9 so that the transplanting device 11 can be operated to elevate and lower. Reference numeral 24 denotes a stop clutch, which is mounted on a transmission shaft 25 for branching and transmitting power to the transmission portion on the side of each sub-transmission case 12b in the main transmission case 12a. The stop clutch 24 can be moved by being biased by a spring 27 to the transmission shaft 25 to a clutch drive gear 26 having a clutch claw 26a that is freely rotatably attached to the transmission shaft 25 and transmitted and rotated. Further, a clutch body 28 having a clutch claw 28a that is wedge-mounted on the transmission shaft 25 and is integrally rotated is mounted so that the clutch claws 26a and 28a can be disengaged from each other. When the clutch pin 29 abuts, the clutch body 28 is moved against the transmission shaft 25 against the spring 27.
The number of the implanting tools 14a and 14b mounted on the rotating case 15, that is, two clutch cams 30 are provided so that the clutch pawls 26a and 28a can be disengaged from moving upward. When the transmission shaft 25 is "disengaged" at two locations during one rotation due to the operation of the stop clutch 24 of the plural-position fixed position stop type, the implant 14a of the rotating case 15 is always provided.
14b is set to stop at a higher level than the lower surface of the leveling floats 16, 17, 17. Further, the transplanting tool 14a or 14b on one side is located immediately before dividing the seedling from the seedling mounting table 13 side, and the transplanting tool 14b or 14a on the other side is located above the lower surface of the leveling float immediately after transplanting the seedling. Setting to stop is even more appropriate. That is, the side view of FIG. 1, whereas after the side of the implant 14a is obtained by dividing the seedlings from Naeno table 13 side, after the implant 14b of the other side were transplanted seedlings, two of implant 14a · Although the state where 14b has been rotated to substantially the same height is shown, the implanters 14a and 14b set and stopped as described above stop before rotating to the positions of the implanters 14a and 14b shown in FIG. in particular name is, therefore, two of the implant 14a · 14b
Stops at a position where the posterior implant is lower than the anterior implant . Such implants 14a, if illustrate 14b stop position, for example, is as shown in FIG. The clutch pin 29 is interlocked with the lifting operation lever 23 by a wire 31. When the hydraulic switching valve 21 is switched to the side where the transplantation device 11 is raised, the wire 31 is loosened and the pin 29 is moved downward to contact the taper side surface of the cam body 30 so that the clutch 24 is turned off. Reference numeral 32 denotes a wire for interlocking the hydraulic pressure switching valve 21 and the operation lever 23. Reference numeral 33 in the hydraulic circuit of FIG. 4 denotes a hydraulic pump, 34 denotes a tank, and 35 denotes a relief valve. Next, the operation of the above example will be described. The seedlings are placed and accommodated in each of the seedling mounting stands 13... While the riding tractor 1 is running, the ground leveling floats 16, 17, 16.
17 is brought into contact with the soil surface of the paddy field, and when each part is transmitted and rotated, the transmission shaft 25 is rotated, and the clutch 24 in which the clutch claws 28a and 26a of the clutch body 28 and the clutch drive gear 26 are engaged is in the "on" state. , The rotating case 1 is connected via the respective transmission mechanisms of the branched sub-transmission cases 12b.
5 ... it is rotation transmission, with an installed two each implant 14a · 14b are this exercise drawing a transplant locus, the
Transplanted into soil surface to be leveled by preparative 16, 17, 17 - two of leveling flow of the lower from Naeno table 13 ... which reciprocates by dividing a share min increments seedlings to right and left alternately each implant 14a-14b Is done. Therefore, the seedlings are transplanted at a high speed with little vibration. During the transplanting operation, when the levee approaches and turns, the raising / lowering operation lever 23 is operated to switch the hydraulic switching valve 21 to raise the transplanting device 11. At this time, the wire 31 is relaxed, and the clutch pin 29 is moved down by the spring. Then, the pin 29 comes into contact with the cam body 30 of the rotating clutch body 28, and the clutch body 28
7, the clutch pawl 28a of the clutch body 28 is disengaged from the clutch pawl 26a of the clutch drive gear 26, and the transmission shaft 25 is stopped. In this case, since the clutch body 28 is provided with the two cam bodies 30, the transmission shaft 25 is stopped at two places during one rotation, and the transmission shaft 25 is immediately Stops,
For this reason, the rotating cases 15, 15 are stopped by half a rotation when the clutch is stopped. Therefore, the transplanting device 11 does not split the seedlings during the ascent and releases the seedlings, and the seedlings are not scattered on the soil surface. Next, when the seedling plant 11 is lowered after the turning, the grounding floats 16, 17, and 17 are brought into contact with the ground, and then the clutch pin 29 is disengaged from the cam body 30. Then, the clutch 24 is turned “on” and transplantation is started. Then, the seedling planting machine, the two
