Another arm 17 is fixed to the other end of the shaft 16, and a pin 17a is implanted in the arm 17 so as to protrude inward.

Furthermore, the shaft 16 is provided with a connecting plate 5.
5. The first plate 13, the second plate 19, and the sensing rod 12 are each rotatably supported. On the other hand, an operating rod 56 connected to the traveling clutch lever 5
is connected to the connecting plate 55 via a compression spring 57, and the plate 55 is further connected to the travel clutch arm 3 via a rod 59, and the travel clutch lever 5 is operated to the on or off position. The travel clutch is turned on and off. Further, a long hole 13a is formed in the first plate 13, and the arm 1 is inserted into the long hole 13a.
7 pins 17a are fitted and inserted to form a predetermined play mechanism. Further, the first plate 13 is connected to the operating arm 10 of the hydraulic switching valve 10 via the plate 60 and the rod 61.
Connected to a. The switching valve 10 communicates with the hydraulic cylinder 9, and can be switched to a raised position, a lowered position, and a neutral position depending on the rotational position of its operating arm 10a. Further, a return spring 14 is tensioned on the operating arm 10a, and the spring 14 urges the switching valve 10 toward the lowered position.

The second plate 19 also has long holes 19b,

Since the sensing rod 12 is supported by the shaft 16 by the relatively long boss portion 12c so as to be vertically movable and rotatable, the float 11 is prevented from swinging in the lateral direction.

Next, the operation of this embodiment based on the above configuration will be explained.

[0019] To perform planting work with the walking rice transplanter P,
Operate the traveling clutch lever 5 to the on position to connect the clutch with the traveling clutch arm 3, and
The planting clutch lever 2 is operated to the on position, and the planting clutch arm 1 connects the clutch. As a result, the rice transplanter P runs with the paddy wheels 7 driven, and the planting rod 38 rotates to perform the planting work. At this time, the pin tip 20 that is interlocked with the traveling clutch lever 5
The arm 17 a is located in the middle of the elongated hole 19b of the second plate 19 and is connected to the planting clutch lever 2 via the rod 51, the arm 15, and the shaft 16.
The pin 17a is located in the middle of the elongated hole 13a of the first plate 13. In this state, based on the urging force from the return spring 14 of the switching valve 10, the first
The lug 19a abuts the side surface 13b and the first plate 1
3 and the second plate 19 are in a state of rotating together, and the pins 17a and 20a rotate these plates 13.
, 19 are in an unregulated state, and therefore,
The vertical movement of the float 11 based on earth pressure sensing is transmitted to the sensing rod 12 as a rocking movement, and is further transmitted to the second lug 19c.
Alternatively, it is transmitted to the second plate 19 via the spring 21, and then to the operating arm 10a of the switching valve 10 via the first plate 13, plate 60, and rod 61 that rotate together. As a result, the switching valve 10 is switched to a raised position, a lowered position, and a neutral position so that the body 35 is at a constant height relative to the field surface based on the earth pressure sensing of the float 11, and the hydraulic cylinder 9 is operated. The height of the machine is automatically controlled by moving the paddy wheels 7, 7 up and down.

Note that even if one or both of the traveling clutch lever 5 and the planting clutch lever 2 are operated to the off position, the pins 17 and 20a are located in the middle of the long holes 13a and 19b and the plates 13 and 19 The switching valve 10 is automatically controlled based on the vertical movement of the float 11, as described above, without interfering with the free movement of the float 11.

Next, when the rice transplanter P reaches the headland and turns, the planting clutch lever 2 is operated to the fixed position while the traveling clutch lever 5 is held in the engaged position. Then, the planting clutch arm 1 disengages the clutch and stops the rotation of the planting rod 38 (see FIG. 3), and the pin 17a of the plate 17 is inserted into the elongated hole through the rod 51, collar 53, plate 15, and shaft 16. It comes into contact with the upper end of 13a. In this position, the first plate 13 is prevented from rotating in the downward direction, and the switching valve 10 is not in the downward position, but is in a semi-automatic upward state in which only the upward direction is allowed. In this state, when the operator lifts the handle 36 upward, the distance between the front part of the float 11 and the fuselage 35 becomes narrower, and the sensing rod 12 is rotated clockwise, causing the spring 21 and the second plate 19 to become narrower. and rotating the first plate 13 in the same direction via the first lug 19a,
Switch the switching valve 10 to the up position. This results in
The hydraulic cylinder 9 lowers the wheels 7, 7 and raises the body 35. Then, when the body 35 rises by the desired amount, the handle 36 is lowered to bring the rice transplanter P into a horizontal state, but at this time, the first plate 13 is rotated in the downward (counterclockwise) direction, regulated by the pin 17a. Since this is prevented, the switching valve 10 is held in the neutral position and the fuselage 35 is fixed in the raised position. At this time, the front part of the float 11 hangs down, the sensing rod 12 rotates counterclockwise, and the second plate 19 also rotates in the same direction due to contact with the second lug 19c. The only difference is that the lug 19a and the side surface 13b are separated from each other, and the first plate 13 is not affected in any way.

Furthermore, when supplying seedlings to the seedling table 37 of the rice transplanter P, the planting clutch lever 2 is set to the on or off position, and the traveling clutch lever 5 is operated to the down position. Then, the traveling clutch 3 is disconnected, and
The rod tip 20a abuts the rear end of the elongated hole 19b, and the second
The plate 19 is restricted from rotating in the upward (clockwise) direction. In this position, from the float 11 to the sensing rod 12
Even if the second plate 19 is rotated in the upward (clockwise) direction, the rotation of the second plate 19 is restricted by the rod tip 20a, and therefore the switching valve 10 is placed in the upward position via the first plate 13. It becomes a semi-automatic state where only the downward direction is allowed. In this state, the fuselage 35 is in a lowered position where a predetermined earth pressure acts on the float 11, and even if the handle 36 is lifted to raise the fuselage, the fuselage 35 is maintained in the lowered position.

Furthermore, in order to stop the height control of the rice transplanter P and fix the body 35 for transportation or storage, the traveling clutch lever 5 is operated to the lower position, and the planting clutch lever 2 is moved to the fixed position. Operate to. In this state, both the traveling clutch 3 and the planting clutch 1 are in a disengaged state, and the pin 17a contacts the lower end of the elongated hole 13a of the first plate 13 to prevent the plate from rotating in the downward (counterclockwise) direction. At the same time, the rod tip 20a comes into contact with the rear end of the elongated hole 19b of the second plate 19 to restrict rotation of the plate in the upward (clockwise) direction. Therefore, the switching valve 10 is fixed at the neutral position, and the body 35 is maintained at a predetermined height regardless of the movement of the float 11.

[0024] Regardless of the operating position of the traveling clutch lever 5, that is, even if it is in the engaged position and in the traveling state,
Even if the machine is in the lowered position, when the planting clutch lever 2 is operated to the raised position, the plate 17 is rotated in the raised (clockwise) direction via the rod 51, collar 53, plate 15, and shaft 16. , further pin 17a
comes into contact with the end of the elongated hole 13a to rotate the first plate 13 in the upward direction, and the operation arm 10a of the switching valve 10 is moved back against the spring 14 to the upward position. As a result, the hydraulic cylinder 9 swings the chain case 40, lowers the paddy wheels 7, 7, and raises the body 35. At this time, the float 11 hangs down and relatively rotates the second plate 19 counterclockwise via the sensing rod 12, but the first lug 19a only separates from the side surface 13b, and the first plate 13 The movement in the upward direction of
Similarly, even when the movement of the plate 19 in the upward direction is restricted, the movement of the first plate 13 is not hindered, simply because the first lug 19a moves away from the side surface 13b.

Therefore, according to this embodiment, when the planting clutch lever 2 is operated to the up position, priority is given to the fuselage 35.
, so that the aircraft can be raised quickly even in an emergency, and in this case, it is sufficient to operate the planted clutch lever 5 against the return spring 14, and it can be operated lightly and the steering feeling can be improved. .

Furthermore, since the first plate 13 and the second plate 19 are separated, the operating system from the planting clutch lever 2 and the operating system from the traveling clutch lever 5 can be adjusted independently, is easy.

Furthermore, the respective operating rods 51 and 56 from the planting clutch lever 2 and the traveling clutch lever 5
Since the connecting parts 15 (plate) and 19 (second plate) and each clutch lever 1 (planting clutch arm) and 55 (connecting plate) for lifting and lowering the aircraft are arranged on the top,
The number of operation linking members such as wires can be reduced, the structure can be simplified and costs can be reduced, and maintainability and appearance can also be improved.

Although the above-mentioned embodiment has been described with respect to a walk-behind rice transplanter, the present invention is not limited to this and can be similarly applied to other paddy field working machines such as a paddy field flooding direct sowing machine.

Next, another embodiment will be explained with reference to FIG.
