If the length is longer than 6, the rotation rate of the shaft 25 will be greater than the rotation rate of the left-right axis 10. Therefore, if the lengths of the arms 21 and 26 are determined appropriately, the right mounting arm 3 will be longer than the rear wheel mounting arm 3. Even though it is longer than the arm 24, the right front wheel 7 (the left front wheel 6 is also the same) and the rear wheel 23 move up and down at the same rate. In addition, in the above case, the amount of movement of the tip of the arm 21 is large when the arm 21 is facing downward as shown in FIG.
Even if the rotation rate is the same, there is almost no movement in the front or back direction. Therefore, even if the mounting angles of the arms 21 and 26 are changed, the right front wheel 7 (the left front wheel 6 is also the same) and the rear wheel 23 can be moved up and down at the same rate.
（作用） 次に作用を述べる。(effect) Next, we will discuss the effect.
機体を前進させて植付けするときは、左前輪６
と右前輪７とで畝を跨いで行なう。 When moving the aircraft forward for planting, turn the left front wheel 6.
straddle the ridge with the right front wheel 7.
このとき、畝の高さが低いときは、エヤシリン
ダー８のロツド９を引つ込ませる（第１図で右方
に移動させる）。すると、ロツド９の長孔２８に
よりアーム１１のピン２９を引くので、アーム１
１は右回動し、アーム１１が固定されている左右
方向軸１０を右回転させる。左右方向軸１０の右
回転により、これに固定されている突片１３は右
回動し、突片１３の上端に軸止しているロツド１
６を介して腕１７を右回動させる。腕１７は前輪
右取付用アーム３に固定されているから腕１７の
右回動により前輪右取付用アーム３を右回動さ
せ、右前輪７を上動させる。 At this time, when the height of the ridge is low, the rod 9 of the air cylinder 8 is retracted (moved to the right in Fig. 1). Then, the long hole 28 of the rod 9 pulls the pin 29 of the arm 11, so the arm 1
1 rotates clockwise, causing the left-right axis 10 to which the arm 11 is fixed to rotate clockwise. As the left-right shaft 10 rotates clockwise, the protrusion 13 fixed thereto rotates clockwise, and the rod 1 fixed to the upper end of the protrusion 13 rotates clockwise.
6 to rotate the arm 17 to the right. Since the arm 17 is fixed to the right front wheel mounting arm 3, right rotation of the arm 17 causes the right front wheel mounting arm 3 to rotate clockwise, thereby moving the right front wheel 7 upward.
同様に左右方向軸１０の右回転により、これに
固定されている突片１２は右回動し、突片１２の
上端に軸止しているロツド１４を介して腕１５を
右回動させる。腕１５は前輪左取付用アーム２
に、調節板１８、調節孔１９、ピン２０を介して
連結されているから、腕１５の右回動により前輪
左取付用アーム２を右回動させ、左前輪６を上動
させる。 Similarly, by clockwise rotation of the left-right shaft 10, the protrusion 12 fixed thereto rotates clockwise, causing the arm 15 to rotate clockwise via the rod 14 fixed to the upper end of the protrusion 12. Arm 15 is front wheel left mounting arm 2
Since they are connected through the adjustment plate 18, adjustment hole 19, and pin 20, the right rotation of the arm 15 causes the left front wheel mounting arm 2 to rotate to the right, and the left front wheel 6 to move upward.
また、左右方向軸１０が右回転すると、左右方
向軸１０に固定されているアーム２１は右回転
し、アーム２１に軸止されているロツド２２を後
動させる。ロツド２２が後動すると、軸２５に固
定されているアーム２６を軸２５ごと左回動さ
せ、軸２５に固定されている後輪取付用アーム２
４を介して、後輪２３を上動させる。 Further, when the left-right shaft 10 rotates clockwise, the arm 21 fixed to the left-right shaft 10 rotates clockwise, causing the rod 22 fixed to the arm 21 to move backward. When the rod 22 moves backward, the arm 26 fixed to the shaft 25 is rotated counterclockwise together with the shaft 25, and the rear wheel mounting arm 2 fixed to the shaft 25 is rotated to the left.
4, the rear wheel 23 is moved upward.
左前輪６および右前輪７で跨いだ畝が高いとき
は、前記とは逆に、エヤシリンダ一８のロツド９
を押し出す（第１図で左方に移動させる）。する
と、前記とは全く反対に作用して、左前輪６，右
前輪７，後輪２３を下動させる。 When the ridges straddled by the front left wheel 6 and the front right wheel 7 are high, contrary to the above, the rod 9 of the air cylinder 18
Push out (move it to the left in Figure 1). Then, the action is completely opposite to that described above, and the left front wheel 6, right front wheel 7, and rear wheel 23 are moved downward.
しかして、傾斜地の場合は、ピン２０を引き抜
いて、調節板１８に形成されている他の調節孔１
９にピン２０を掛け変え、左前輪６を独立して上
下調節（第３図）する。 Therefore, in the case of a slope, the pin 20 can be pulled out and the other adjustment hole 1 formed in the adjustment plate 18
9 and pin 20, and independently adjust the left front wheel 6 up and down (Fig. 3).
以上の左前輪６と右前輪７および後輪２３の上
下調節は、互いが、リンク結合であるから、前輪
右取付用アーム３と後輪取付用アーム２４とが全
く同一長さでないと、上下動の割合が相違するこ
とになる。たとえば、第１図では、前輪右取付用
アーム３の方が後輪取付用アーム２４より長いか
ら、右前輪７は後輪２３に比し大きく上下動す
る。 The above-mentioned vertical adjustment of the left front wheel 6, right front wheel 7, and rear wheel 23 is performed by linking each other, so if the front wheel right mounting arm 3 and the rear wheel mounting arm 24 are not of exactly the same length, This means that the rate of movement will be different. For example, in FIG. 1, the right front wheel mounting arm 3 is longer than the rear wheel mounting arm 24, so the right front wheel 7 moves up and down more than the rear wheel 23.
しかしながら、たとえばアーム２１の方をアー
ム２６よりも長くしておくと、左右方向軸１０の
回転割合よりも軸２５の回転割合が大きくなるの
で、アーム２１とアーム２６の長さを適宜に定め
ると、前記右取付用アーム３が前記後輪取付用ア
ーム２４より長くとも、同一割合で右前輪７（左
前輪６も同じ）と後輪２３を上下動させうる。ま
た、上記の場合、アーム２１の先端の動き量は、
アーム２１が第１図のように下向きのときは左右
方向軸１０の回動量が同じでも、前後方向に大き
く動くことになるが、アーム２１を第１図で横向
きに取付けたときは、回動割合は同じでも前後方
向の動きは殆どなくなる。それゆえ、アーム２１
とアーム２６の取付角度を変えても、同一割合で
右前輪７（左前輪６も同じ）と後輪２３に上下動
させうる。 However, if the arm 21 is made longer than the arm 26, for example, the rotation rate of the shaft 25 will be greater than the rotation rate of the left-right axis 10, so if the lengths of the arms 21 and 26 are determined appropriately. Even if the right mounting arm 3 is longer than the rear wheel mounting arm 24, the right front wheel 7 (the left front wheel 6 is also the same) and the rear wheel 23 can be moved up and down at the same rate. Furthermore, in the above case, the amount of movement of the tip of the arm 21 is
When the arm 21 is facing downward as shown in Figure 1, it will move a lot in the front and rear directions even if the amount of rotation of the left-right axis 10 is the same, but when the arm 21 is installed horizontally as shown in Figure 1, the rotation will be large. Although the ratio remains the same, there is almost no movement in the front-back direction. Therefore, arm 21
Even if the mounting angle of the arm 26 is changed, the right front wheel 7 (the left front wheel 6 is also the same) and the rear wheel 23 can be moved up and down at the same rate.

A seedling transplanter that has a right front wheel and a rear wheel that is attached to the rear of the transplanter body via a rear wheel attachment arm is known. There is an issue with countermeasures against vertical movement of the wheels. In particular, when the front wheels and the rear wheels are simultaneously moved up and down in accordance with the height of the ridges, the lengths of the mounting arms are different, so the width of the up-and-down movement is different between the front wheels and the rear wheels.
