（産業上の利用分野）
本考案は田植機やバインダー、トラクタなどの
車輪走行タイプの農作業機における補助車輪に関
するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to auxiliary wheels for wheeled agricultural machines such as rice transplanters, binders, and tractors.
（従来の技術）
一般に、田植機等の農作業機においては、その

ている。(Prior Art) In general, in agricultural machines such as rice transplanters, depending on whether the wheels sink due to the condition of the seedling planting mud, the wheels are lowered to lift the machine, or in the case of a riding rice transplanter, the machine is lifted up. Measures have been taken to raise the seedling planting device to maintain a constant seedling planting depth.
（考案が解決しようとする問題点）
しかしながら、苗植付け後にその苗間を車輪が
通過するものにあつては、車輪の泥中への大きな
沈みはは、既植苗の姿勢を乱すことになり、ある

みられ、一般的に軟弱な場所において余り車輪が
土中に沈まないようにすることが要求される。(Problem to be solved by the invention) However, when the wheels pass between the seedlings after planting, the large sinking of the wheels into the mud disturbs the posture of the already planted seedlings. Alternatively, in the case where seedlings are planted after the wheels pass, not only does the planting posture itself become disturbed by disturbing the planting mud surface, but sometimes the seedlings are planted upside down. It is required to avoid sinking.
（問題点を解決するための手段）
そこで本考案にあつては、補助車輪を用いるこ
とにより、接地圧を小さくして両車輪の沈み込み
を抑制している。(Means for Solving the Problems) Therefore, in the present invention, by using auxiliary wheels, the ground contact pressure is reduced and the sinking of both wheels is suppressed.

回時解脱すべく構成したものである。 The present invention is configured so that the above-mentioned auxiliary wheels are driven when the aircraft is moving straight, and rotate idly when the aircraft is turning.Specifically, the auxiliary wheels are located outside of the drive wheels and relative to the drive wheel axle. They are connected via a clutch, and the clutch is configured to be directly engaged when the aircraft is moving straight ahead, and released when it is turning.
（実施例）
以下、本考案の実施例を図面について説明す
る。(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

操作で舵取りができるようになつている。 The one shown in Figure 1 shows a riding rice transplanter with 6 rows of rice transplanting.
There are wheels 5, 5 and 6, 6 that are driven by an engine 4 mounted on the aircraft, and a seat 8 is located on a gate-shaped frame 7 that stands up from the front fuselage 2, and the steering can be done by rotating a handle 9 in the front. It's becoming like that.
又、機体の前方には植付部１０がある。 Further, there is a planting section 10 at the front of the aircraft body.

ス１７との間にスプリング１６を弾設した。 The present invention is based on the drive wheels 6 of the rice transplanter as described above.
In order to attach an auxiliary wheel to the outside of the auxiliary wheel 6, a clutch 12 is installed on the drive wheel shaft 11 as shown in FIG.
4, and the auxiliary wheel 13 is fitted onto the driving wheel shaft 11 so that these mutual claws can mesh with each other, and a spring 16 is installed between the collar 15 fixed to the end of the axle and the boss 17 of the auxiliary wheel 13. was set up.

となつて回転する。 With the above configuration, the clutches 12 and 14 are always engaged with each other by the spring 16 when traveling straight, and the power of the drive wheel shaft 11 is transmitted to the auxiliary wheels 13, and when turning, the clutches 12 and 14 are transmitted to the auxiliary wheels 13, and when turning, the clutches 12 and 14 are transmitted to the auxiliary wheels 13. For example, when turning around the drive wheel and auxiliary wheels (none of which are shown) on the opposite side of the drive wheel 6 in FIG. 2, the center of the turn, i.e. The inner auxiliary wheels remain as they are, and the aircraft moves outwardly against the force of the springs, i.e. the drive wheels 6 and auxiliary wheels 13 shown.
As the clutches move to the side, the inner clutches disengage each other and the auxiliary wheels are free-wheeling, whereas on the outside as shown in the drawing, the clutches 12 and 14
The auxiliary wheels 13 mesh with the drive wheels 6, and the auxiliary wheels 13 rotate together with the drive wheels 6.

に直進走行することができる。(Effects of the invention) In this invention, when the aircraft is moving straight, the clutch of the drive wheel shaft and the clutch of the auxiliary wheels are engaged by the spring, and the same driving force as that of the drive wheels is transmitted to the auxiliary wheels, allowing the aircraft to move straight. Since the force for the drive is distributed to each wheel, the driving force is large and the stability in the lateral direction is increased. For example, even if the driving wheel slips, the driving force transmitted to the auxiliary wheels can be used. This allows the aircraft to travel smoothly in a straight line without being hindered.

きる。 In addition, when the aircraft turns, if the auxiliary wheels are driven as one unit as when going straight, the drive wheels become the center of the turn with respect to the field, so the auxiliary wheels do not rotate, but are opposite to the direction of rotation. As the wheel moves forward in the direction, the resistance increases and the turning radius becomes larger, but in the case of this invention, the inner auxiliary wheels rotate freely when turning, so there is less resistance and the turning radius is prevented from increasing. At the same time, since the outer auxiliary wheels are driven integrally with the drive wheels, the driving and traction forces are large, allowing the aircraft to turn smoothly.
