に維持させながら進行される。As the soil tillage gets deeper, the vehicle body (3) tries to sink,
The ground pressure acting on the sensor floats (4) and (5) with the 1-ring becomes higher, which causes the Q (wheels (1) and 2) to move closer to the vehicle body (
3) to prevent the vehicle body (3) from sinking. It is advanced while maintaining the upper position at a certain position.

の高さを一定位置に維持される。” When the two-ring JJI board becomes shallower, the vehicle body (3) is pushed up via the wheels (1) and (2), and the ground pressure of the sensor floats (4 and 5) against the soil surface becomes lower. As a result, the wheels (1) and (2) are controlled to rise relative to the vehicle body (3), and the height of the body (3) from the soil surface is maintained at a constant position.

わゆるローリング制御が行われる。If there is a difference in the depth of the tiller between the areas where the left and right wheels (1) and (2) come in contact with each other, the vehicle body (3) will tend to tilt to the left and right, but the depth will be lower than the area of the standard tiller. Between the sensor flow (4), (5) on the side where the sensor flow has become shallower or the side where it has become shallower and the wheels ('l), (2) on the opposite side,
jlj rings (1) and (2) as above, independently on the left and right sides, respectively.
A lifting control action is performed, and so-called rolling control is performed, in which the vehicle body (3) moves while maintaining the C-ki-qi attitude to prevent the vehicle body (3) from tilting to the left or right.

。In soil where the soil tillage plate is extremely uneven, soil with a lot of foreign matter such as straw waste, etc., adjust the pressure of this connection spring (7) strongly.
In this way, the connection force between the sensor floats 1-(4) and (5) is strengthened, and the vertical operation is enhanced.As a result, the pair of left and right sensor floats (4) and (5) are integrated. It moves up and down under such a connection force and detects changes in ground pressure.
The left and right wheels 71j (1) and (2) are controlled to descend by y1. For this reason, the detection of changes in the ground pressure of the sensor floats (4) and (5) becomes insensitive, and the elevation control and rolling control become dull.

Moreover, since such adjustment of the connecting force is operated in conjunction with the operating mechanism (6) that operates other operating points, it is possible to perform not only the 1゛l'' 1 seedling planting run but also the 1t゛1 planting operation. Even when switching between running postures, it is possible to adjust or change the connection force according to the working condition f5 by operating C and C at the same time, and the operation is quick, accurate, and easy to use.

Rolling control, 51 descending control 431! ? -11, is often stopped, but in this configuration, the sensor float (4) (5) itself becomes insensitive to the left and right vertical movement, so the sensor float (4') when turning (5
) itself can also be stabilized. Also, at the same time as the vehicle finishes turning and travels straight, the connection force of sensor flow 1-(4) and (5) becomes weaker and becomes more sensitive, so rolling control 31τ during 11° 1 planting stroke can be performed accurately. .

できる。If such a configuration is used, the connection force should be weakened during relatively low-speed driving such as during planting, and the sensor flow 1- (4) (5) should be made more sensitive during seedling planting work. However, when driving at high speeds in fields or on roads, the sensitivity of these sensor floats (4) and (5) may be made dull to slow rolling control, etc.

A pair of left and right wheels that detect changes in ground pressure on the soil surface and control the wheels (1) and (2) on the corresponding side to raise and lower to maintain the vehicle body (3) in a horizontal position in the left and right directions. A connecting spring (7) is provided between the sensor floats (4) and (5), which can adjust the connecting force between these two sensor floats (4) and (5) in conjunction with the operating mechanism (6) of the other operating point. A running device for the seedling planting machine provided. 2 The above operating mechanism (6) serves as a planting clutch (8),
The traveling device for a seedling transplanter according to claim 1, wherein the connection force of the connection spring (7) is strengthened when the planting clutch (8) is disengaged and weakened when it is engaged. 3 The operating mechanism (6) serves as a strike clutch (9),
2. The running device for a seedling transplanter according to claim 1, wherein the coupling force of the coupling spring (7) is strengthened when the running clutch (9) is disengaged, and is weakened when it is engaged. 4 The operating mechanism (6) serves as a traveling transmission (10), and by shifting the traveling transmission (10) to a high traveling speed, the connecting force of the connection spring (7) is strengthened, and the driving speed is increased to the seedling planting traveling speed. A traveling device for a seedling transplanter according to claim 1, which is configured to be interlocked in a relationship that is weakened by changing speed. 5.
