本考案は、自走機体の後方に苗植付装置を昇降
調節自在に設けてある乗用型田植機の車輪ローリ
ングロツク装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wheel rolling lock device for a riding type rice transplanter in which a seedling planting device is provided at the rear of a self-propelled machine body so as to be adjustable up and down.
この種の、車輪をローリング自在に構成してあ
る田植機としては、自走機体に対して前輪をロー
リングさせる構造のもの（例えば、実開昭60−
134008号公報参照）が一般的に知られている。
This type of rice transplanter whose wheels are configured to roll freely is one that has a structure that allows the front wheels to roll relative to the self-propelled body (for example,
134008) is generally known.
ところが、上述のように前輪をローリングさせ

その凹凸に応じて、操縦者の位置する搭乗部が大
きく揺れて操縦姿勢が乱されることがあり、ま
た、前輪をローリング自在に設けるために、前輪
側の車高をある程度高く維持する必要があつて機
体重心を低く設定し難いという問題があつた。 However, as mentioned above, with a structure that allows the front wheels to roll, when the tiller becomes uneven,
Depending on the unevenness, the riding area where the operator is located may shake significantly and the control posture may be disturbed.In addition, in order to provide the front wheels with rolling ability, it is necessary to maintain the vehicle height of the front wheels to a certain degree. There was a problem that it was difficult to set the center of gravity of the aircraft low.
このため、近年では、前輪ローリング構造に比
べて操縦性に優れ、機体の低重心化や圃場への出
入り・畦越えに有利な後輪ローリング構造を、前
輪ローリング構造に代わつて採用した乗用型田植
機も開発された（例えば、特開昭60−244213公
報、及び特開昭60−248108公報参照）。 For this reason, in recent years, riding-type rice growers have adopted a rear-wheel rolling structure instead of a front-wheel rolling structure, which has superior maneuverability compared to a front-wheel rolling structure, lowers the center of gravity, and is advantageous for entering and exiting fields and crossing ridges. A machine has also been developed (for example, see Japanese Patent Application Laid-open No. 60-244213 and Japanese Patent Application Laid-open No. 60-248108).

用型田植機では、前輪ローリング構造に比べて操
縦性に優れ、機体の低重心化や圃場への出入り・
畦越えに有利なものであるが、その反面次のよう
な新たな問題を生じる。
As mentioned above, the riding rice transplanter that adopts the rear-wheel rolling structure has superior maneuverability compared to the front-wheel rolling structure, and has a lower center of gravity and easier movement in and out of the field.
Although this is advantageous for crossing ridges, it also creates new problems such as the following.
つまり、田植機では、枕地を少なくして苗植付
作業の高効率化を図るべく、極力回行半径を小さ
くしたい要望がある。このため、田植機の全長を
できるだけコンパクト化する設計がなされてお

機体に対してローリング可能に連結されているの
で、後輪のローリング動と植付装置のローリング
動が同方向に大きく行われると、場合によつて後
輪と苗載せ台とが干渉するおそれがあつた。 In other words, there is a demand for a rice transplanter to have a turning radius as small as possible in order to reduce headlands and increase the efficiency of seedling planting work. For this reason, the overall length of the rice transplanter is designed to be as compact as possible, and since the seedling planting device is normally connected to the machine body in a rollable manner for good planting, the rear wheels If the rolling motion and the rolling motion of the planting device were largely performed in the same direction, there was a risk that the rear wheels and the seedling platform would interfere in some cases.
本考案の目的は、利点の多い後輪ローリング構

する点にある。 The purpose of this invention is to adopt a rear wheel rolling structure that has many advantages, while also providing a means for preventing mutual interference between the rear wheels and the seedling stand. The purpose is to enable it to be used as a means for avoiding damage to members when wheel rolling is permitted.

A pair of stoppers 10, 10 for the seedling planting device 5 are arranged on the left and right sides of the shaft center P, and are oscillated via a single rotating support shaft 12 having a bending portion that bypasses the transmission shaft 11 for the seedling planting device 5. The wheel transmission case 6 can be freely attached to the front stay part 7a.
A rolling lock device is constructed that can be freely released and fixed in a state parallel or almost parallel to the traveling body so as not to swing. That is, when the rotation support shaft 12 is rotated by the operating mechanism 13 provided at one end thereof, the pair of stoppers 10, 10 swing together, and the lock is released as shown in FIG. In this state, the stoppers 10, 10 are arranged between the wheel transmission case 6 and the fuselage frame 7 to avoid direct contact between them, and the stoppers 10, 10 and the wheel transmission case 6 are arranged between them.
A large gap is provided between the two for rocking movement. That is, the free end 6c of the wheel transmission case 6 and the second
A state appears in which the stopper portion 10b is disposed opposite to the stopper portion 10b with a relatively large gap.

The stoppers 10, 10 and the wheel transmission case 6 are configured to be close to each other. That is, a state is created in which the first stopper portion 10a and the free end portion 6c are opposed to each other and are closer to each other than in the deactivated state.

A spring 15 that is attached to and biases the pair of stoppers 10, 10 to swing acts on the arm 16, which is rotatable integrally with the rotation support shaft 12, and biases the pair of stoppers 10, 10 to the operating state. The control lever 14 is linked to the operating lever 14 so as to be switched by the swinging of the operating lever 14 between a first operating state in which the stoppers 10 and 10 are urged toward the released state .

トツパー１０，１０が切換わるのである。 That is, when the operating lever 14 is operated to the first operating position ON where it is received and supported by the first operating portion 17a of the stopper 17, the spring 15 enters the first operating state as shown in FIG. For the rotational operation of the rotational support shaft 12,
The pair of stoppers 10, 10 are switched to and maintained in the operating state, and the operating lever 1
4 to the second operating position OFF, where it is received and supported by the second operating portion 17b of the stopper 17, the spring 15 moves to the second operating position as shown in FIG.
When the spring 15 is activated, the pair of stoppers 1
0 and 10 are switched to and maintained in the deactivated state. Then, when the operating lever 14 is switched from one of the first operating position ON and the second operating position OFF to the other, the wheel transmission case 6 is attached to one of the stoppers 10 which is in the operating state or the operating release state. Even if the stopper 10 is in contact or the portion 10c between the first stopper part 10a and the second stopper part 10b of the stopper 10 is in contact with the wheel transmission case 6 and the stopper 10 is not switched, the aircraft can still run. As the wheel transmission case 6 comes out of contact with the stopper 10, it has already been switched to the first operating state or the second operating state for switching the operating lever 14, as shown in FIG. Because of the spring 15 present, the pair of stoppers 10, 10 are automatically switched to the side corresponding to the side where the operating lever 14 is present.
