Description

[Detailed description of the invention] The present invention is based on a marker that protrudes outward from the front side of the aircraft so that the steering operation is performed based on the marker line on the outside of the aircraft side or the already planted seedlings. Regarding the type rice transplanter.

Generally, a rice transplanter rotates the machine 180 degrees after finishing rice planting in one direction.
The rice is then maneuvered so that it turns around and plants the rice in the opposite direction to the previous rice planting direction, but generally the space for this accompanying movement, the so-called headland, is made as small as possible to create an efficient straight line. Since the machine-planted portion is often made large, the front marker may come into contact with the ridge during the above-mentioned rotation and be damaged.

Therefore, when the aircraft turns, the marker is stored inside the aircraft in conjunction with the disengagement operation of the planting clutch, but conventionally, as shown in Japanese Utility Model Application Publication No. 50-96527,
The left and right markers were stored together in the fuselage in conjunction with the disengagement operation of the planting clutch.

According to this structure, when aligning the marker with the reference line after the aircraft turns, if the timing of the marker's protrusion operation is off, the aircraft will come too close to the reference line and the tip of the marker will cross the reference line, causing damage to the aircraft. There was a drawback that it was necessary to make steering corrections.

The present invention aims to provide a walk-behind rice transplanter in which the markers do not collide with ridges when the machine turns, and the markers can be smoothly aligned after the machine turns.

The characteristic configuration of the walk-behind rice transplanter of the present invention is that the planting clutch has swing levers on both the left and right sides of the operating lever ((), which can be switched between a locked state and a disengaged state with respect to the operating lever). The swing lever is connected to left and right markers provided at the front of the machine via a link mechanism, respectively, and when the swing lever is engaged with the operating lever, the planting clutch is disengaged by the operating lever. The vehicle is characterized in that the marker is configured to be stored within the vehicle as the vehicle is operated.

In other words, when the aircraft turns, only the outer markers that draw a large turning radius can be stored inside the aircraft, so the markers do not collide with the ridges, while the inner markers are kept in a protruding state. By doing so, the marker can be smoothly aligned with the reference line after the aircraft turns.

Furthermore, when crossing ridges or driving on the road after work is completed,
Since the structure is such that the left and right markers can be stored simultaneously, the markers do not come into contact with other objects, and the operability is excellent.

Embodiments of the present invention will be described below with reference to the drawings.

Figure 1 shows the entire rice transplanter.

From the front to the rear of the fuselage frame 1, the main components are the engine 2, the traveling mission case 3, the traveling wheels 4.4, the planting mission case 5, the planting claws 6, and the seedling stand 7. The attached device is provided with a control handle 9, and a float 10, 10 is disposed below the fuselage frame 1.

An operating lever 12 of a planting clutch 11 for inputting the drive of the planting device 8 is provided at the rear end grip portion of the handle 9.

With this structure, seedlings are continuously planted on the rice field at approximately constant intervals by the operation of a worker following the machine from the rear.

13.13 is an index marker provided on the front of the aircraft.

Reference numerals 14 and 14 denote line drawing markers for forming marker lines, which are provided at the rear of the fuselage.

A clutch arm 21 is connected to the planting clutch operating lever 12 via a release wire 22.

The structure of the index markers 13, 13 will be explained.

Marker rods 16, 16, which telescopically support the markers 13, 13, are pivotably supported at the middle of the marker rods 16, 16 near both lateral sides of the protector 15 below the engine 2, and the stopper 23 .23 prevents the forward movement from the extended state, and the springs 24, 2
4, configured to elastically maintain the overhanging state,
Spherical index portions 20°2 provided at the tips of the rods 16, 16
0 protrudes outward on both sides of the fuselage.

One end side of link mechanisms 26, 26 whose intermediate portions are pivoted to the body via a horizontal shaft 21 is pivoted to each of the rods 16, 16, respectively, and the other end side of each link mechanism 26, 26 is connected to a planting clutch. They are connected to inverted-shaped swing levers 25, 25 on both sides of the operating lever 12, respectively.

The protruding end of the swing lever 25° 25 is viewed from above 9
It is configured so that it can be attached with a 0 degree angle change, and the operating lever 12 and the swing levers 25, 25 are configured so that they can be respectively brought into an interlocked state and a disengaged state.

With this configuration, at the same time when the operating lever 12 is swung backward to disconnect and operate the planting clutch 11, the oscillating levers 25, 25, which are engaged with the operating lever 12, and each link mechanism 26, Through 26, each field 16,1
6 forward against the spring 24, and both rods 16
, 16 swing around the pivot point, and the index objects 20, 20 move rearward and are housed in the fuselage.

Then, when the operating lever 12 is swung forward to engage the planting clutch 11, the indicator portions 20, 20 are automatically extended laterally outward, and are in a state suitable for planting work.

Then, when one of the swinging 1/bars is disengaged from the operating lever 12, only the marker on the desired side can be stored.

With this configuration, when the aircraft is rotating, the marker on the inside of the rotation can be made to protrude, and when the aircraft is placed in a suitable position for planting before the planting clutch is engaged, this marker can be used. Protruding markers can be used, making it easier to plant in the correct location from the beginning of the planting process.
