Description

[Detailed description of the invention] Industrial applications The present invention relates to a traveling device for a seedling transplanter.

Conventional technology A pair of left and right wheels and a sensor float are provided on the vehicle body so that they can move up and down, and between the small wheel and the sensor float on the opposite side, the wheels are activated by detecting changes in ground pressure by the sensor float. The structure is such that the vehicle body is controlled to be raised and lowered to maintain the left and right tree-like posture.

Problems to be Solved by the Invention A traveling device that raises and lowers the wheels by detecting changes in ground pressure using sensor flow 1 and maintains and controls the left and right water moat-like posture of the vehicle body has a problem in that In fields where the board is extremely uneven or where there is a lot of foreign matter such as straw waste straw hats, if the independent vertical movement of the left and right sensor floats is too sensitive, the -L downward movement of the wheel becomes too sensitive, causing malfunctions and ill-effects. (Your body may sway violently from side to side, or your running may become unstable.)

Means for Solving the Problems This invention detects changes in the ground pressure on the l1 surface and raises the wheels (1) and (2) on the corresponding side to move the vehicle body (3) into a horizontal water V position. Between the left and right pair of sensor floats (4) and (5), the sensor floats (4) and (5)
1, which is provided with a connecting spring (7) that can provide four nodes of connecting force between the
°^ The configuration of the traveling device of the transplanter.

Effect of the Invention The pair of left and right wheels (1) and (2) are driven to run the vehicle body (3), and then the seedling planting device performs the seedling planting action.

+1 (wheels (1) and (2) run and rotate in contact with the rice cake l!1 part under the soil, and sensor floats (4) and (5) slide on the -L ring part while these wheels (1) (2) and sensor floats (4), (5), etc., the vehicle body (3) travels while being supported on the field soil, and when the depth of the plowing plate where the wheels (1) and (2) rotate changes, the sensor Float (4) (5
) detects changes in the ground pressure of sliding with this soil surface.

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.

” 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.

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.

The left and right pair of sensor floats (4) and (5) are activated by the pressure of the connecting spring (7).
) and (5) are adjusted.

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.

Also, at the edge of a ridge or under soft soil conditions, i! l Adjust the pressure of the tying bolt (7) weakly and attach the sensor float (4).
) (5) If the connection force of (5) is weakened to facilitate left and right independent operation, the detection of changes in ground pressure by each sensor flow 1-(4) and (5) will become more sensitive, resulting in lowering control and rolling control. becomes easier to carry out.

The connection force of the connection spring (7) can be adjusted as follows.

It is operated in conjunction with an operating mechanism (6) that operates other operating points other than this connection force adjustment.

Effects of the Invention In this way, by adjusting the connection spring (7) to adjust the connection force between the left and right sensor floats (4) and (5), it is possible to , sensor 70-) (4) (5)': By changing the sensitivity of detecting changes in ground pressure with respect to the ring cylinder, accurate running can be performed by one-step lowering control or rolling control of the wheels. 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.

The operation mechanism (6) serves as a planting clutch (8), and the connection force of the connection spring (7) is strengthened when the planting clutch (8) is disengaged and weakened when it is engaged. Configure interlocking.

In the case of such a configuration, since seedling planting work is not performed when the planting clutch (8) is in the disengaged state, there is little need for sensitive rolling control, etc., and the left and right sensor floats (4) ) (5) Connection spring between (7)
strengthen the connection force.

Rocking of the vehicle body (3) can be reduced. Furthermore, when the planting clutch (8) is engaged to perform seedling planting work, the coupling force is weakened and rolling control etc. are performed sensitively, thereby stabilizing the seedling planting.

In addition, the operating mechanism (6) serves as a running clutch (9), and when the running clutch (9) is disengaged, the connection spring (7)
The connection is structured so that the connection force is strengthened, and the connection force is weakened when entering.

In the case of such Mh 11 (body (3) tends to tilt toward the - side due to the deviation of Without this, it is possible to reduce the shaking of the vehicle body (3) and perform stable turning.In addition, in the case of such a turn,
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. .

In addition, the operation Ia structure (6) is a traveling transmission type 21 (1G), and by changing the traveling transmission (10) to a high traveling speed, the connecting force of the connection spring (7) is strengthened, and the seedling traveling is performed. The relationship is linked so that the relationship is weakened by shifting to a higher speed.

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.
It is possible to make stable running by making it difficult for the vehicle to swing itself.

Also, the above operating mechanism (6) is the previous vl! M! , 13 As the R device (11), by applying this forward/reverse motion cutter device (11) to reverse travel, the connecting force of the connection spring (7) is strengthened, and forward travel is possible! ! /J Constructed in a relationship that weakens the connection force by holding it.

When using such a configuration, it is based on forward movement. I, l, When planting, weaken the connection force and connect the left and right sensor floats.
(4) The sensitivity of (5) is made sensitive to perform rolling control etc. accurately, but when moving backward, this sensor 20-) (4
) The sensitivity of (5) can be made dull to make it difficult to perform these rolling controls, etc., and stable reverse movement can be performed. or,
During this backward movement, the 1"1"1" planting operation is performed by -H stop.
