損する等の欠点がある。In the conventional simultaneous tilling rice transplanter described above, when the rotary device is lowered, the transplant device also descends at the same time. Therefore, the transplant device is grounded on the road or on the rice field, and the transplant device is grounded. If the tiller is run simultaneously with the cultivation in this state, the transplanting device is dragged, causing problems such as damage to the transplanting device and large power consumption. In addition, even if you try to transplant rice from the ridge, there will be an untiled rice field on the ridge just as long as the length of the machine before and after the transplanting device. As a result, there are drawbacks such as abnormal transplantation, and early mounting or breakage of the implant nail.

A rotary device having a tilling claw provided on a tilling shaft via an elevating mechanism is attached, and a transplanting device having a planting claw on the rear side of the rotary device is vertically arranged freely by a vertical automatic mechanism. In a rice transplanter, an automatic up-down mechanism of the transplanting device is switched between a descending side and an ascending side in conjunction with an on / off operation of a planting lever for controlling the operation of the planting claw, and the planting lever is constructed. The cut-off operation causes the automatic up-and-down mechanism of the transplanting device to be switched to the ascending side to raise only the transplanting device with respect to the rotary device and stop the operation of the planting claw. Is what you do.

が解決する。[Function] A rotary device for supporting a tilling shaft with a tilling claw attached to the rear of a traveling vehicle body is disposed via a lifting mechanism consisting of a three-point link device, and a rice seedling on a seedling mounting table is provided on the rear side. An implanting device for implanting a plant with a stud is vertically arranged by an automatic up-and-down mechanism, and a hydraulic lever is provided near the driver's seat of the traveling vehicle body.
The rotary device and the transplant device are simultaneously moved up and down by the elevating mechanism by the operation described above, and the transplant device is moved up and down automatically by the on / off operation of the planting lever provided near the driver's seat of the traveling vehicle body. In conjunction with the mechanism, switching operation is performed on the descending side and the ascending side irrespective of the rotary device. By the cutting operation of the transplanting lever, the automatic up-down mechanism of the transplanting device switches the transplanting device to the ascending side, and operates only the transplanting device with respect to the rotary device, and stops the operation of the transplanting claw. As a result, the implant device does not touch the ground and is not dragged so that it is not damaged and consumes less power. In addition, by the operation of inserting the planting lever, the vertical mechanism of the transplanting device is switched to the descending side while the rotary device is lowered and the transplanting device is lowered, and the planting claw is operated. So
Since the rotary device can plow the ridge, there is no untiled rice field, and the transplanting device can transplant rice seedlings to the cultivated and crushed rice field from the ridge. And the problems such as wear and breakage of the planting nail are solved.

The hydraulic valves 32 are connected to a spool shaft 32a of a hydraulic valve 32 which controls the expansion and contraction of a piston 13a of the double-acting hydraulic cylinder 13 by being supplied by oils 13b, 13c, 13d and 13e. When the planting lever 14 is turned off, the connection of the planter clutch 18 is disconnected, so that power is not transmitted to the output shaft 19 of the sub-case 17, so that the planting claws 8 are stopped and the planter clutch 18 is stopped.
Is pulled up, and the front side of the float 22 is lifted up by raising the tip 27a with the rear pin 26 as a fulcrum. A key-shaped link 28 pivotally attached to the base 27 is connected to the float 22.
The link 29 is pivoted upward along with the rise of the front side, and the connecting rod 31 pivotally connected to the link 29 rotates the spool shaft 32a of the hydraulic valve 32 upward. Since the pressure oil fed by the switching of the rotation of the spool shaft 32a operates to contract the piston 13a of the double-acting hydraulic cylinder 13, the transplanting device 9 is configured to operate upward. .

When the planting lever 14 is turned off, the planting claws 8 are stopped, and the automatic up-and-down mechanism 15 is connected to the transplanting device 9.
Only the transplantation device 9 can be raised by switching only the ascending side, so that the transplanting device 9 is not dragged and is not damaged even when the traveling vehicle body 1 travels.
Further, when the rotary device 5 and the transplanting device 9 are simultaneously raised by the operation of the hydraulic lever 2a, and the planting lever 14 is in the cutting operation, the hydraulic lever 2a is lowered. Then, the rotary device 5 descends, but the transplanting device 9 does not descend, so that a higher ground height can be obtained, and it is safe without touching the rice field or on the road. Also, when the planting lever 14 is operated while tilling and crushing soil while maintaining the descending posture of the rotary device 5, the automatic vertical mechanism 15 switches the transplanting device 9 to the descending side, and operates. The transplanting device 9 is lowered onto the plowed and crushed rice field 30 and the planting claws 8.
Is driven and the rice seedlings 10 placed on the seedling mounting table 7 can be transplanted with the planting claws 8 for each planting streak. As shown in FIG. The transplanting device 9 with the planting lever 14 turned off is positioned above the ridge 41, and the vehicle travels on the traveling vehicle body 1 with the rotary device 5 uncultivated. When the transplanting device 9 enters the cultivated and crushed rice field 30 while cultivating and crushing the soil 40, if the planting lever 14 is inserted as shown in FIG.
Since the planting claw 8 is driven down and the rice seedling 10 can be planted, the uncultivated rice field 40 of the machine length of the transplanting device 9 is not present, and the paddy rice is lower than the ridge 41. Because the seedling 10 can be transplanted, the planting nail 8

化が図れる。As described above, according to the present invention, a rotary device provided with a tilling claw on a tilling shaft is provided behind a traveling vehicle body via an elevating mechanism. In a cultivating simultaneous rice transplanter in which a transplanting device having a planting claw on its side is freely movable up and down by an up-down automatic mechanism, the transplanting device is moved up and down in conjunction with an on / off operation of a planting lever that controls the operation of the planting claw. The automatic mechanism is configured to be operated to switch between the descending side and the ascending side, and the up-down automatic mechanism of the transplanting apparatus is operated to be switched to the ascending side by the cutting operation of the transplanting lever, so that the transplanting is performed on the rotary apparatus. Since only the device is raised and the operation of the implant nail is stopped, the transplant device is not dragged and is not damaged. Also, there is no wear or breakage of the planting nail. And since transplantation can be performed from the edge of the ridge, there is little supplementary planting work after planting, and labor can be saved.
