[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation wire arranging structure in a transplanter applicable to a rice transplanter, a field transplanter and the like.

[0002]

2. Description of the Related Art In general, a rice transplanter or the like is provided with a mission case driven by an engine in front of the fuselage, and a transmission case extending rearward from the mission case.
A steering handle is provided at the rear of the fuselage, and a seedling table is provided above and below the handle frame of the steering handle so as to reciprocate horizontally. The left and right clutch arms on the side of the mission case disposed in front of the fuselage and the left and right clutch levers provided at the steering handle position are interlocked and connected via operation wires for connecting the both. I have. When these operation wires extend from the position of the steering handle to the position of the clutch arm in front of the fuselage while bypassing the lower end of the seedling platform that moves reciprocally to the left and right, an airframe component (for example, a handle) that bypasses below the seedling platform. Frame, transmission case, etc.).

[0003]

In the above-mentioned conventional apparatus, when the clamp holding the operation wire is released, the operation wire comes into contact with the lower end of the reciprocating laterally moving seedling mounting table, There is a problem that the seedling on the seedling mounting table is brought into contact with a planting claw that operates to plant the seedling on the rice field at the lower end side of the table and is damaged. Also,
Even when the operation wire is to be stopped, the hand must be inserted into a narrow place below the fuselage, and the work of arranging the operation wire is difficult.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and has been made in order to provide an arrangement structure of an operation wire in an implanting machine which can eliminate these disadvantages. A transmission case 4 extending rearward from the transmission case 3 driven by the engine E is provided, and a base end of a handle frame 6 extending obliquely upward is fixed to a rear portion of the transmission case 4.
In the transplanting machine provided with the seedling table 10 which reciprocates right and left and reciprocates, the base end of the handle frame 6 is displaced from the rear end position of the transmission case 4, and an opening 6a is provided in front of the base end of the handle frame 6. And one end of an operation wire 19 of the transplanter is connected to an operation tool 15 provided on the distal end side of the handle frame 6, passed through the handle frame 6, bypassing the lower part of the seedling table 10, and opening the opening. 6a to extend forward from the fuselage.

[0005]

According to the above-described structure, the operation wire 19 connected to the operation tool 15 provided on the distal end side of the handle frame 6 is
Simply by passing the wire into the handle frame 6 and pushing it, the distal end of the operation wire 19 is guided in the handle frame 6, bypasses below the seedling mounting table 10, and is taken out from the opening 6 a formed in front of the base end of the handle frame 6. And can be extended from the opening 6a to the front of the fuselage.

[0006]

According to the present invention, since the operation wire 19 connected to the operation tool 15 provided on the distal end side of the handle frame 6 is inserted into the handle frame 6, the operation wire 19 is different from the conventional one. The clamp that releases the seedling is released, and the operation wire contacts the lower end of the seedling table that moves reciprocatingly to the left and right, and planting the seedlings on the seedling table on the rice field at the lower end of the seedling table. There is no contact with nails and no damage. In addition, the operation of arranging the operation wire 19 can be performed simply by pushing the operation wire 19 through the handle frame 6, and the tip of the operation wire 19 is guided in the handle frame 6, bypasses the lower part of the seedling mounting table 10, and moves the handle frame 6. Can be taken out from the opening 6a formed in front of the base end of the vehicle, and can be arranged in front of the fuselage through the opening 6a, so that the operation of arranging the operation wires can be performed extremely easily.

[0007]

Next, an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 3 and 4, the walking type rice transplanter T includes a float 1 that slides on a rice field, and a pair of left and right traveling wheels 2 that travel on a plow. An engine E is provided in front of the float 1.
A transmission case 4 extending in the front-rear direction and a rotating shaft for driving the seedling mounting table 10 in a laterally reciprocating manner are provided at the rear left and right positions of the mission case 3. 5 are disposed opposite to each other at an interval K. In this way, the planting transmission case 4 is disposed at a position displaced to one side on the left and right with respect to the virtual body center line S.

At the rear end of the planting transmission case 4, a base end of a handle frame 6 extending obliquely upward is disposed on the virtual body center line S, and both are connected and fixed. A center portion of a steering handle 9 having a pair of left and right grips 7, 7 extending to both left and right sides and extending rearward is fixed to an upper portion of the handle frame 6. Above the handle frame 6, a seedling mounting table 10 is provided which is inclined along the direction of inclination of the frame 6 and reciprocates horizontally.
A seedling receiver 11 for receiving a leading edge of a mat-like seedling (not shown) placed on the seedling mounting table 10 is provided at a lower end of the seedling mounting table 10.
Is provided. A seedling outlet 12 is opened in the seedling receiver 11, and a planting claw 14 fixed to the tip side of the planting rod 13 faces the seedling outlet 12.

The handle frame 6 is formed of a pipe member, and its base end is displaced to the right of the planting transmission case 4 and fixed on the virtual center line S of the body. An opening 6a is formed at the front. A pair of left and right clutch levers 15, 15 are respectively attached to left and right grip portions 7, 7 of the steering handle 9 provided on the distal end side of the handle frame 6. Further, a pair of left and right side clutches (not shown) for intermittently supplying power to the traveling wheels 2 is provided in the mixing case 3, and the switching shaft 16 of the side clutch is connected to the mixing case 3. A pair of left and right clutch arms 17, 17 projecting downward and crossing each other are attached to the projections, respectively. The clutch arm 17 of the mixing case 3 and the clutch lever 15 of the grip 7 are connected to each other by a pair of left and right operation wires (Bowden wires) 19, 19.
One end is connected to a clutch lever 15 which is an operating tool, and the other end is guided through the handle frame 6 and bypasses the lower part of the seedling mounting table 10 from the opening 6a to the clutch arm 17 in front of the fuselage. It is arranged to be connected.

A throttle lever 20 is attached to the right grip 7. The other end of an operation wire (Bowden wire) 21 having one end connected to the throttle lever 20 is connected to a governor of the engine E. The operation wire 21 is inserted into the handle frame 6 together with the operation wire 19 and protrudes from the front end opening 6a of the frame 6 to the outside.

Therefore, as shown in FIG.
And 21 can be easily inserted and removed, and the operation of disposing the operation wires 19 and 21 can be performed extremely easily. In addition, since the operation wire is guided through the inside of the handle frame 6, damage to the operation wire can be reliably prevented as compared with a case where the operation wire is exposed to the outside. In addition, water or the like that has entered the inside of the handle frame 6 can easily flow out to the outside from the opening 6a.

In the operation wire 19 of the present embodiment, each outer wire of the operation wire 19 extending downward from the clutch lever 15 is inserted to a position where it is slightly inserted into the handle frame 6, and is operated by an outer stop member (not shown). One side of an operation wire 19 connected to the clutch arm 17 is detachably attached to the clutch arm 17 and is formed of only an inner wire from inside the handle frame 6.
