ものである。Specifically, in a rice transplanter in which the seedlings on the seedling platform of the seedling planting device are picked up with a planting claw as the machine moves, and the seedlings are planted in the field, an automatic device is used to detect the remaining amount of seedlings on the seedling platform. This is what I did.

あった。Generally, when planting seedlings using a rice transplanter, the operator operates the machine while checking the state of planting the seedlings and the amount of seedlings remaining on the seedling platform. When planting seedlings, it is important to check their condition, and when planting seedlings, check the remaining number of seedlings between checking their condition.
Sometimes people overlook the fact that the number of seedlings on the seedling stand is decreasing, and only realize that all the seedlings on the seedling stand have been consumed, for example, when seedlings are missing during planting. Something happened.

するものである。In other words, the present invention focuses on the fact that when water is present between two metals with different ionization tendencies, a potential difference occurs between the two metals, and that the seedlings on the seedling stand contain a large amount of water. This method was devised by a method in which two types of metals with different ionization tendencies were placed at a predetermined distance so as to be exposed on the defined surface of the seedling stand, and both metals were electrically isolated from each other. The present invention is characterized in that it is connected to an electric detector so that the amount of seedlings on the seedling stand is detected by the detector.

Two through holes 14 and 15 are formed in the seedling platform 8 of the seedling planting device 5 at a predetermined interval in the vertical direction or width direction, and one of the through holes 14 is filled with a strip-like material having a high ionization tendency. The metal 16 is inserted through the insulator 17, and the outer surface of the metal 16 is placed on the seedling stand 8 while the metal 16 is electrically isolated.
A band-shaped metal 18 with a small ionization tendency is inserted into the other through-hole 15 via an insulator 19, and this metal 18 is electrically In the isolated state, the outer surface of the metal 18 is exposed so as to be substantially flush with the defined surface of the seedling stand 8.

ある。In such a state, when the number of seedlings on the seedling platform 8 decreases due to the planting of seedlings into the field using the planting claws 7, the two metals 16.
The water intervening between 18 disappears, and both metals 16.1
Since the potential difference generated between transistors 8 and 8 disappears, the connection circuit of the transistor
The normally closed contact RL-b of L is closed, the circuit connecting the alarm lamp L to the power source E is closed, and the lamp L lights up.
従って作業者はこの警報ランプＬの点燈に基づいて苗載
