4のギヤ40,41が噛合してある。 The power transmission device of the present invention is constituted by this crank link 17. The rotation shaft 19 is pivotally supported by rotation shaft bearings 29 , 29 and supported by a fertilizer application device support rod 20 . Intermittent drive shafts 31 and 32 are located in the upper dispensing cases 7 and 7 of the left and right fertilizer application devices, respectively, in a state that projects in the left and right direction.
gears 38, 39 and drive shafts 43, 4 in the fertilizer applicator
4 gears 40 and 41 are in mesh with each other.
間欠駆動軸31,32の間には連結軸30が介
在し、条止めピン26,25によつて連結軸30

が装備してあり、該ワンウエイクラツチ24上の
アーム24aと回動軸19上のアーム19aとの
間には連結杆46が装備してある。 A connecting shaft 30 is interposed between the intermittent drive shafts 31 and 32, and the connecting shaft 30
The structure is such that the intermittent drive shafts 31 and 32 interlock with each other. A one-way clutch 24 is mounted on the connecting shaft 30.
A connecting rod 46 is provided between the arm 24a on the one-way clutch 24 and the arm 19a on the rotation shaft 19.
連結軸30上には戻り止めワンウエイクラツチ
23が装備され、該戻り止めワンウエイクラツチ
23と施肥装置支持杆20間には支持体45を装
備してある。 A detent one-way clutch 23 is installed on the connecting shaft 30, and a support 45 is installed between the detent one-way clutch 23 and the fertilizer application device support rod 20.
よつて回転軸28の駆動に伴いクランクアーム

24によつて、連結軸30が回転運動し、左右の
間欠駆動軸31,32も回転して左右の施肥装置
内の繰り出し装置を駆動させるのである。 Therefore, when the crank arm 18 rotates as the rotating shaft 28 is driven, the crank link 17 converts the rotational motion into reciprocating motion, causing the rotating shaft 19 to reciprocate via the crank arm 13, and the arm 1
9a, the connecting rod 46, the arm 24a, and the one-way clutch 24 rotate. Further, the one-way clutch 24 rotates the connecting shaft 30, and the left and right intermittent drive shafts 31, 32 also rotate to drive the feeding devices in the left and right fertilizer applicators.
なお、任意の条止めピン26,25を引き抜く
ことによつて不必要な施肥装置側の間欠駆動軸3
1,32を停止させ、施肥をストツプさせること
も可能となる。 In addition, by pulling out the arbitrary row fixing pins 26 and 25, the unnecessary intermittent drive shaft 3 on the fertilizer application device side can be removed.
It is also possible to stop fertilization by stopping the fertilizers 1 and 32.
また、上記の構造の他にも第2図に示す如く、
回動軸19を装備せずに片側の間欠駆動軸31の
外端部にワンウエイクラツチ24を直接に付設し

る。 In addition to the above structure, as shown in Figure 2,
By attaching the one-way clutch 24 directly to the outer end of the intermittent drive shaft 31 on one side without equipping the rotation shaft 19 to take in power, it is possible to connect the other end of the intermittent drive shaft 31 to the other end of the fertilization device. It is also possible to have a structure in which the end of the intermittent drive shaft 32 is connected with the row stopper pin 25, and to have a simple structure in which only one of the fertilization devices is stopped by pulling out the row stopper pin 25.
(ヘ) 考案の効果
本考案の構成・作用は以上の如くであり、本考
案によつて生ずる効果を以下に述べる。(f) Effects of the invention The structure and operation of the invention are as described above, and the effects produced by the invention will be described below.
第1に、施肥装置の駆動力取り出し部を、苗載
台駆動ケース9の側面に設けたので、歩行型田植
機のアタツチメントとして、あとから装着する場
合に、従来の植付爪5から動力を取り出していた
ものに比較して、簡単に脱着が行えるのである。 First, since the drive power extraction part of the fertilization device is provided on the side of the seedling stand drive case 9, when it is later attached as an attachment to a walk-behind rice transplanter, it is possible to draw power from the conventional planting claws 5. It's easier to put on and take off compared to what you used to take out.
第2に、施肥タンク1を予備苗載台6の前方
で、走行ラグ車輪2の車軸2aの上方に位置させ
たので、施肥タンク1内の肥料の量が変化して
も、田植機の全体の重心が変化しないので、オペ
レーターの疲労が少ないのである。 Second, since the fertilizer tank 1 is located in front of the preliminary seedling platform 6 and above the axle 2a of the running lug wheel 2, even if the amount of fertilizer in the fertilizer tank 1 changes, the entire rice transplanter Since the center of gravity of the machine does not change, operator fatigue is reduced.
第3に、植付爪5より上方の苗載台駆動ケース
9の側方に回転軸28を突出した施肥装置の駆動
取出部を設けたので、駆動取出部に植付爪5から
跳ね飛ばされた泥土が付着することが無く、また
繰出装置への駆動経路をクランクリンク17のみ

し、施肥量の精度を向上することが出来たのであ
る。 Thirdly, since the drive take-out part of the fertilization device with the rotating shaft 28 protruding from the side of the seedling stand drive case 9 above the planting claw 5 is provided, the drive take-out part is free from being blown away from the planting claw 5. Since the muddy soil does not adhere to the fertilizer, and the drive path to the feeding device can be constructed using only the crank link 17, durability can be improved and accuracy in the amount of fertilizer applied can be improved.
