BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation wire structure in a transplanter applicable to a rice transplanter for planting rice and a planter for rush planting rush.

[0002]

2. Description of the Related Art A general walking type rice transplanter is disclosed in Japanese Utility Model 2-33.
As shown in Japanese Patent Publication No. 452, a handle frame extending obliquely upward is disposed, and a seedling table that reciprocates horizontally from side to side is disposed above the handle frame. It is structured so that it is close to the placed seedling receiver and planting rod and is located at a low position near the rice field. Then, the clutch arm on the mission case side provided in front of the fuselage and the clutch lever on the steering handle provided on the upper part of the handle frame are connected via an operation wire (Boden wire) for connecting the two. Linked and linked. Further, the front end of the handle frame, fixedly connected to the rear end of the front-rear direction of the transmission case extending rearwardly, steering wheel to the handle frame
Is fixed, and an intermediate portion of the operation wire is fixed around a handle frame or the like by a wire clamp or the like.

[0003]

The above-mentioned operation wire is extended at a position extending downward along the rear surface of the laterally moving seedling mounting table and extending forwardly below the seedling receiving receptacle. Therefore, it is generally curved in a “relaxed” state where the ground height near the lower part of the seedling receiver is the lowest. If water or the like enters this operation wire, it will remain in the slack, but the rice transplanter will not be stored and used in a warehouse or the like until planting the following year. There was a problem that the inner wire rusted on the outer wire in some parts and became inoperable.

Accordingly, the present invention has been devised to solve the above-mentioned conventional problems. By discharging water or the like entering the operation wire into the handle frame, the inner wire becomes rusted on the outer wire. An object of the present invention is to provide an operation wire structure in an implanting machine that can prevent the operation from being disabled.

[0005]

In order to achieve the above object, the present invention provides a seedling table 10 which is reciprocally moved laterally right and left above a handle frame 6 having a front end fixed to a rear end of a transmission case 4 and extending obliquely upward. In the walking type rice transplanter T provided, the operation wire 19 provided on the rice transplanter T is moved from the operation handle 9 provided on the upper part of the handle frame 6 to the seedling mounting table 10.
Is housed in a handle frame 6 extending forward through a lower portion of the handle frame 6, and the inside of the handle frame 6 includes only inner wires.

[0006]

[Operation] Accordingly, a transmission case 4 extending rearward, a handle frame 6 having a front end fixed to the rear end of the transmission case 4 and extending diagonally upward,
Seedling table 10 that reciprocates horizontally from side to side and is provided along the top of
Using a walking rice transplanter T equipped with a clutch lever 1
Operating wire 1 stretched between the arm 5 and the clutch arm 17
Numeral 9 is housed in a handle frame 6 extending forward from a steering handle 9 provided above the handle frame 6 below the seedling mounting table 10. The handle frame is made up of only inner wires. , The outer wire is deleted.

The operation wire 19 has a "slack" portion accommodated in the handle frame 6 only for the inner wire, and the outer wire has been deleted, so that the clutch lever 15 or the clutch arm 17 side can be used. Water or the like that has entered the wire 19 does not accumulate in the slack portion of the outer wire as in the related art, and is dropped and discharged into the handle frame 6. Is reliably prevented.

Above the handle frame 6, a seedling table 10 is provided which is inclined along the direction of inclination of the frame 6 and reciprocates horizontally. A seedling receiver 11 is provided for receiving a leading edge of a mat-like seedling (not shown) placed thereon. A seedling receiving port 12 is opened in the seedling receiving body 11, and a planting claw 14 fixed to a tip end side of a planting rod 13 faces the seedling removing port 12.

A pair of left and right clutch levers 15 are attached to the left and right grips 7 provided on the steering handle 9, respectively. 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 located below the case 3. A pair of right and left clutch arms 17 projecting from each other and crossing each other are attached to the projecting portions. 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. It passes through the inside of the handle frame 6 from the front end side of the frame 6 to a predetermined height and protrudes to the outside, and its ends are connected to the clutch lever 15 of the grip portion 7 respectively.
