The front end portion of the connecting rod 5 is detachably attached to the rod connecting portion 20 of the airframe 2. When the front end portion of the connecting rod 5 is removed from the rod connecting portion 20, the retaining pin 24 is pivoted. After being removed from the 21 pin holes, the shaft 21 is pulled out from both holes 22 and 23.

また、連結ロッド5の外周側には2つのコイル状のばね26,27が配設され、この各ばね26,27が当接するばね受け28,29が連結ロッド5に脱着可能に取り付けられている。   Two coil-shaped springs 26 and 27 are disposed on the outer peripheral side of the connecting rod 5, and spring receivers 28 and 29 with which the springs 26 and 27 come into contact are detachably attached to the connecting rod 5. .

さらに、整地体4を機体2に対して水平状の持上状態(板状の整地体4が水平面に略沿った水平姿勢となるハイリフト状態)に固定するためのストッパ体30が回動部材18に脱着可能に取り付けられている。   Further, a stopper body 30 for fixing the leveling body 4 to the horizontal lifting state with respect to the machine body 2 (a high lift state in which the plate-shaped leveling body 4 is in a horizontal posture substantially along a horizontal plane) is provided as a rotating member 18. It is detachably attached to.

ストッパ体30は、連結ロッド5のピン用孔(図示せず)および回動部材18のピン用孔18bに挿入されその連結ロッド5の回動部材18に対する移動を規制するストッパピン31と、このストッパピン31による移動規制を解除する際に操作される操作レバー32とを有している。   The stopper body 30 is inserted into a pin hole (not shown) of the connecting rod 5 and a pin hole 18b of the rotating member 18, and a stopper pin 31 for restricting movement of the connecting rod 5 with respect to the rotating member 18, And an operation lever 32 that is operated when the movement restriction by the stopper pin 31 is released.

ここで、耕耘体3および整地体4等のメンテナンスや洗浄をする際には、ストッパ体30を使用して整地体4を持上状態に固定すればよいが(特許文献1の図1)、整地体4を持上状態にしたまま耕耘体3で深く耕耘作業をする際、つまり整地体持上状態での深耕作業の際には、ストッパピン31の損傷を回避するために、図10および図11に示すように、連結ロッド5を使用して整地体4を持上状態に固定する。   Here, when performing maintenance or cleaning of the tillage body 3 and the leveling body 4, etc., the leveling body 4 may be fixed in a lifted state using the stopper body 30 (FIG. 1 of Patent Document 1). In order to avoid damage to the stopper pin 31 when deeply cultivating with the cultivating body 3 while the leveling body 4 is in the lifted state, that is, during deep plowing work with the leveling body being lifted, FIG. As shown in FIG. 11, the leveling body 4 is fixed to the lifted state using the connecting rod 5.

この場合、ストッパ体30のほか、ばね26,27、ばね受け28,29および回動部材18を取り外す。その後、連結ロッド5の後端部を、その前端部と同じように、軸(止めピン)36および抜止ピン(Rピン)37を用いて、整地体4のロッド連結部17の後端部に脱着可能に取り付ける。   In this case, in addition to the stopper body 30, the springs 26 and 27, the spring receivers 28 and 29, and the rotating member 18 are removed. Thereafter, the rear end portion of the connecting rod 5 is attached to the rear end portion of the rod connecting portion 17 of the leveling body 4 by using the shaft (stop pin) 36 and the retaining pin (R pin) 37 in the same manner as the front end portion thereof.

そして、互いに対向する整地体4のロッド連結部17の孔44および第2取付体57の筒状部73の孔74に、鍔部36aを有する軸(止めピン)36が挿脱可能に挿入され、この軸36が抜止ピン(Rピン)37によって両孔44,74から抜けないようになっている。また、第2取付体57の筒状部73の両突出部分73aが、整地体4のロッド連結部17の位置決め部材41の引掛受け部42に引っ掛けられている。   A shaft (stop pin) 36 having a flange 36a is removably inserted into the hole 44 of the rod connecting part 17 of the leveling body 4 and the hole 74 of the cylindrical part 73 of the second mounting body 57 facing each other. The shaft 36 is prevented from being removed from both holes 44 and 74 by a retaining pin (R pin) 37. Further, both projecting portions 73 a of the cylindrical portion 73 of the second attachment body 57 are hooked on the hook receiving portion 42 of the positioning member 41 of the rod connecting portion 17 of the leveling body 4.

次に、整地体固定装置51の作用等を説明する。   Next, the operation and the like of the leveling body fixing device 51 will be described.

通常の耕耘整地作業とは異なる整地体持上状態での深耕作業を行う際には、作業者は、図1に示すように、例えば2本の連結ロッド5と2本の整地体固定装置51とを使用して、整地体4を機体2に対してガタつかないように持上状態に固定する。   When performing deep plowing work in a state where the leveling body is lifted, which is different from normal plowing leveling work, as shown in FIG. 1, the operator, for example, includes two connecting rods 5 and two leveling body fixing devices 51. Then, the leveling body 4 is fixed in the lifted state so as not to rattle with respect to the airframe 2.

すなわち、連結ロッド5に関しては、ストッパ体30、ばね26,27、ばね受け28,29および回動部材18を取り外した後、連結ロッド5の後端部を整地体4のロッド連結部17に軸36を介して取り付ける。なお、連結ロッド5の前端部は、機体2のロッド連結部20に軸21を介して取り付けられたままである。   That is, with respect to the connecting rod 5, after removing the stopper body 30, the springs 26 and 27, the spring receivers 28 and 29, and the rotating member 18, the rear end portion of the connecting rod 5 is pivoted to the rod connecting portion 17 of the leveling body 4. Install through 36. Note that the front end portion of the connecting rod 5 remains attached to the rod connecting portion 20 of the airframe 2 via the shaft 21.

また、整地体固定装置51に関しては、ストッパ体30等とともに連結ロッド5も取り外した後、第1取付体56の前端部を機体2のロッド連結部20に軸21を介して取り付け、かつ、第2取付体57の後端部を整地体4のロッド連結部17に軸36を介して取り付ける。   Regarding the leveling body fixing device 51, after removing the connecting rod 5 together with the stopper body 30 and the like, the front end portion of the first mounting body 56 is attached to the rod connecting portion 20 of the machine body 2 via the shaft 21, and 2. The rear end portion of the attachment body 57 is attached to the rod connecting portion 17 of the leveling body 4 via the shaft 36.

その後、例えば図3に示すように、作業者が操作体58を一方向に回転操作すると、整地体固定装置51がその操作に応じて縮み動作し、その結果、整地体4が若干たわみ変形するとともに、整地体固定装置51によって整地体4が機体2に対してガタつかないように持上状態に固定される。   Thereafter, for example, as shown in FIG. 3, when the operator rotates the operation body 58 in one direction, the leveling body fixing device 51 is contracted in accordance with the operation, and as a result, the leveling body 4 is slightly bent and deformed. At the same time, the leveling body 4 is fixed in a lifted state by the leveling body fixing device 51 so that the leveling body 4 does not rattle against the body 2.

なお、操作体58を他方向に回転操作した場合でも、整地体固定装置51がその操作に応じて伸び動作し、その結果同様に、整地体4がガタつかないように持上状態に固定される。   Even when the operating body 58 is rotated in the other direction, the leveling body fixing device 51 extends in response to the operation, and as a result, the leveling body 4 is fixed in the lifted state so as not to rattle. The

次いで、作業者は、トラクタを運転して、トラクタの走行により整地体持上状態の農作業機1を移動させると、整地体4が持上状態に固定されたまま、耕耘体3が回転して深く耕耘作業を行う。   Next, when the operator operates the tractor and moves the farm implement 1 in a state where the leveling body is lifted by traveling of the tractor, the tiller 3 rotates while the leveling body 4 is fixed in the lifting state. Till deeply.

この整地体持上状態での深耕作業の際、耕耘体3が回転により振動するが、連結ロッド5の前端側における孔22,23と軸21との間の隙間や連結ロッド5の後端側における孔44,45と軸36との間の隙間等に起因して整地体4がガタつくようなことはない。   At the time of deep plowing with the leveling body held up, the cultivating body 3 vibrates due to the rotation. The ground leveling body 4 does not rattle due to the gaps between the holes 44 and 45 and the shaft 36 in FIG.

そして、このような整地体固定装置51によれば、農作業機1を用いて整地体持上状態での深耕作業をする際に、整地体固定装置51を連結ロッド5に代えて取り付けて使用することにより、各部の孔ガタ等を無くすことができるため、その作業時における整地体4のガタつきを防止でき、騒音を低減できる。   And according to such a leveling body fixing | fixed apparatus 51, when carrying out the deep plowing work in the state of leveling body holding | maintenance using the agricultural working machine 1, it replaces with the connecting rod 5, and uses it. As a result, it is possible to eliminate the backlash and the like of each part, so that it is possible to prevent the ground leveling body 4 from rattling during the work and to reduce noise.

また、操作体58は互いに螺旋方向が異なる第1ねじ孔部63および第2ねじ孔部64を有し、第1取付体56は操作体58の第1ねじ孔部63に螺合されたねじ軸部66を有し、第2取付体57は操作体58の第2ねじ孔部64に螺合されたねじ軸部71を有するため、操作体58の回転操作によって整地体4を機体2に対してガタつかないように持上状態に適切に固定することができる。   The operating body 58 has a first screw hole portion 63 and a second screw hole portion 64 having different spiral directions, and the first mounting body 56 is a screw screwed into the first screw hole portion 63 of the operating body 58. Since the second mounting body 57 has the screw shaft portion 71 screwed into the second screw hole portion 64 of the operating body 58, the leveling body 4 is attached to the machine body 2 by rotating the operating body 58. On the other hand, it can be appropriately fixed to the lifting state so as not to rattle.

なお、前記整地体固定装置51は、操作体58を操作する構成には限定されず、例えば回転ハンドル部の操作で伸縮する構成等でもよい。   The leveling body fixing device 51 is not limited to the configuration for operating the operating body 58, and may be configured to expand and contract by operating the rotary handle portion, for example.
