Conventional devices of this type were not equipped with any measuring equipment to measure the density of seedlings placed on the mat seedlings placed in the seedling tank. The amount of seedlings supplied was adjusted by predicting the number of seedlings and actually counting them at the time of planting.

However, if you adjust the supply of seedlings based on confusion, there is a risk of making incorrect adjustments depending on the growth of the seedlings, etc. Also, if you do not count the number of seedlings each time before planting, it will reduce work efficiency. Not only that, but it was also extremely troublesome.

The detection body 13 and the electrical contacts 16 and 17 operate as a microswitch Sc in the electrical circuit shown in FIG. In addition, the embodiment shown in FIG. 1 shows a seedling tank 1 having a pair of seedling stands arranged on the left and right,
A seedling stem detector 13 is provided on the left side of the seedling dividing opening corresponding to the seedling tank on the left side of the page. Although this is an example in which the seedlings are detected only when the seedling tank 1 moves to the right, it is of course possible to provide the detectors 13 in each of the left and right seedling tanks. It goes without saying that they may be provided separately on the left and right sides of 4. In addition, in the case of the working drawing example,
When using soil-attached mat seedlings A that have been sown and raised under the same conditions, continuous detection or detection of only the picked seedlings and parts can be performed, excluding the detection of all-attached mat seedlings. be. FIG. 5 is a circuit diagram of the electric hawk.

In addition, the seedling density of mat seedlings A with soil does not change much when seedlings are sown and raised simultaneously in seedling boxes under the same conditions, but
When growing by changing the variety, bed soil, or place of raising seedlings, the density of seedlings naturally changes. In addition, for a single mat seedling A with soil, there is almost no difference in the number of plants grown in the left, right, lateral, and vertical directions when compared in units of small divided area of one plant, so this can be assumed to be constant. I regard it as such.

On the other hand, a DC power source E, an internal resistor R3, and a primary coil 28 are incorporated in the closed circuit including the microswitch Sc.

Then, the seedling tank 1 is reciprocally moved left and right by the reciprocating lateral movement mechanism, and the front end surface of the ten-mat seedling A mounted in the seedling tank 1 is received by the seedbed guide receiver 2. , and the seedbeds are successively fed out laterally into the seedling dividing opening 4. Then, the seedling dividing claw 5 that moves up and down intervenes in the seedling dividing opening 4, separates the individual seedlings, engages them as they are, reaches the lower soil surface, and plants them. The seedling planting work is carried out in this way, but when the seedling tank 1 moves to the right in FIG. Micro switch Sc is 0N,
It is set to 0FF. Each time this switch is turned on, a voltage is generated on the secondary coil 29 side of the transformer 30. Therefore, the voltage on the secondary coil 29 side is generated corresponding to the number of times the microswitch SC(7) is turned ON.
The voltage is integrated by the integrating circuit 32a, and a voltage proportional to the number of ON cycles is extracted. In other words, the greater the number of seedlings, the greater the voltage generated. On the other hand, since the horizontal reciprocating speed of the seedling tank 1 is proportional to the number of rotations of the seedling dividing claw 5, the electromagnetic pickup device 18 generates a voltage proportional to the horizontal movement speed, and the dial 23 also generates a voltage proportional to the horizontal movement speed. Properly adjust the settings proportionally using the potentiometer 24. The voltage E2 generated by the transformer 30 and the voltage e1 adjusted by the potentiometer 24 are passed through waveform shaping circuits 25 and 32 and arithmetic circuits 26 and 33, respectively, into voltages e''2 and e''1. The two voltages 2 and e″1 are compared and amplified using a servo amplifier to rotate the DC surfomotor. When the number of ON times is large and the voltage on the e″2 side becomes larger than the voltage on the e″, side (e″2>e″,), the DC servo motor 8 is reversed and the gears 9, 1
The bolt 7 rotates normally (clockwise) through 0, 11, and 12,
The seedbed guide receiver 2 is automatically adjusted to move toward the seedling tank 1 side (in the direction away from the rotation trajectory of the seedling dividing claws 5) via the nut 6 to reduce the amount of seedbed division and the number of divided seedlings. By adjusting the direction, the number of seedlings per plant can be kept constant despite the high seedling density.

Conversely, when e″1>e″2, the DC servo motor 8
is rotated in the normal direction, the bolt 7 is reversely rotated, and the seedbed guide receiver 2 is moved to the side opposite to the seedling tank 1 through the nut 6 to increase the number of divided stems of the seedlings. In this way, the number of divided fungal stalks is automatically controlled to be constant. At this time, the number of seedlings counted by the seedling detector 13 is not changed by adjusting the back and forth movement of the seedbed guide receiver 2. Therefore, as the seedbed guide receiver 2 moves, the resistance of the output potentiometer 31 is automatically adjusted via the gears 10, 34, 35, and 36, so that accurate voltage comparisons can be made at all times. Soil-attached mat seedlings A that are loaded into the seedling tank 1 of the rice transplanter and planted as described above.
The seedling density is automatically detected during the seedling planting work, and the amount of seedling division by the seedling dividing claws 5 is changed based on this seedling density, so that the number of seedlings to be planted for one plant is controlled to be constant.

Since this invention is configured as described above, the seedling density of the mat seedlings with soil in the seedling tank can be measured during the seedling planting work, thereby preventing erroneous seedling supply amount adjustment. The density of seedlings can be detected at the start of the planting process, improving work efficiency without having to check the seedling supply before planting and adjust the amount of seedlings supplied.
