Claims

[Claims for Utility Model Registration] (1) A nozzle 54 that spouts a liquid agent 90 into a rice field;
The liquid agent 9 is driven by the rotational power of the planting claw 32.
0 to the nozzle 54; and an on-off valve 5 that is interposed between the pump 46 and the nozzle 54 and opens and closes in synchronization with the operation of the planting claw 32.
6. A liquid agent spraying device for a rice transplanter, comprising: (2) Link mechanisms 62, 64, 66, 8 that convert the rotational power of the planting claw 32 into reciprocating displacement and transmit it.
8, a swing arm 130 that swings by the link mechanisms 62, 64, 66, 88, and a valve body 142 that rotates in one direction only when the swing arm 130 swings in one direction. The on-off valve 56 alternately opens and closes when the valve body 142 rotates in one direction, and the valve body 142
The liquid agent spraying device for a rice transplanter according to claim 1, further comprising a swing angle adjusting means (84) for adjusting a swing angle of the rice transplanter.
