　本発明は、乗用田植機等の作業機械に具備され、圃場に施肥する施肥装置の技術に関し、特に施肥装置内の肥料の排出及び清掃の効率化を図るための技術に関する。 [Technical Field] The present invention relates to a technique of a fertilizer device that is provided in a work machine such as a riding rice transplanter and applies fertilizer to a farm field, and particularly relates to a technique for improving the efficiency of discharging and cleaning fertilizer in the fertilizer apparatus.
　従来、乗用田植機等の作業機械に具備され、圃場に施肥する施肥装置を、作業姿勢とメンテナンス姿勢とに切り換え可能に構成することで、当該施肥装置の内部に対するメンテナンス性を向上させる技術は公知となっている（例えば、特許文献１参照）。 2. Description of the Related Art Conventionally, a technique for improving the maintainability with respect to the inside of a fertilizing apparatus by configuring a fertilizing apparatus that is provided in a work machine such as a riding rice transplanter and that can be applied to a farm field to be switchable between a working position and a maintenance position is known. (For example, refer to Patent Document 1).
　また、同様にメンテナンス性を向上させる観点から、施肥装置の上部、すなわち、肥料を収容するホッパや前記ホッパ内の肥料を繰り出す繰り出し部等を上方に回動可能に構成された施肥装置も存在する。 Similarly, from the viewpoint of improving maintainability, there is also a fertilizer that is configured so that the upper part of the fertilizer, that is, the hopper that stores the fertilizer, the feeding portion that feeds the fertilizer in the hopper, and the like can be rotated upward. .
　具体的には、前記施肥装置には、左右方向に複数のホッパ及び繰り出し部が並設される。前記複数のホッパ及び繰り出し部のうち、左側のホッパ及び繰り出し部は、前記施肥装置の左端部に設けられる回動支持軸により上方回動可能に支持される。前記複数のホッパ及び繰り出し部のうち、右側のホッパ及び繰り出し部は、前記施肥装置の右端部に設けられる回動支持軸により上方回動可能に支持される。 Specifically, a plurality of hoppers and feeding parts are arranged in parallel in the left-right direction in the fertilizer application apparatus. Of the plurality of hoppers and feeding portions, the left hopper and feeding portion are supported by a turning support shaft provided at the left end portion of the fertilizer application device so as to be rotatable upward. Of the plurality of hoppers and feeding sections, the right hopper and feeding section are supported by a pivot support shaft provided at the right end of the fertilizer application so as to be pivotable upward.
　上述の如く構成された施肥装置においては、前記複数のホッパ及び繰り出し部を上方に回動させることにより、前記複数のホッパ及び繰り出し部の内部に収容された肥料を容易に排出することができ、メンテナンス性を向上させることができる。 In the fertilizer application apparatus configured as described above, the fertilizer accommodated inside the plurality of hoppers and the feeding portion can be easily discharged by rotating the plurality of hoppers and the feeding portion upward. Maintainability can be improved.
　しかし、前記施肥装置に具備される複数の繰り出し部を駆動するための動力は、左右方向に横架された入力軸により伝達される。そのため、上述の如く左側及び右側のホッパ及び繰り出し装置を上方に回動するためには、前記入力軸を中途部において左右に分離する必要があり、当該分離のための作業が煩雑である点で不利であった。
特開２００６－１０１７８３号公報 However, the power for driving the plurality of feeding portions provided in the fertilizer applying apparatus is transmitted by the input shaft horizontally mounted in the left-right direction. Therefore, in order to rotate the left and right hoppers and the feeding device upward as described above, it is necessary to separate the input shaft to the left and right in the middle, and the work for the separation is complicated. It was disadvantageous.

　本発明は、操作部材を操作した場合にのみ、第一入力軸と第二入力軸との連結を解除することができる。また、操作部材を操作しない場合には、連結機構により第一入力軸と第二入力軸とを連結させることができる。さらに、操作部材を長手方向に所定の長さとなるように構成することにより、連結機構が手作業では操作し難い位置に配置されていても、連結機構を容易に操作することができる。 In the present invention, the connection between the first input shaft and the second input shaft can be released only when the operation member is operated. Moreover, when not operating an operation member, a 1st input shaft and a 2nd input shaft can be connected with a connection mechanism. Furthermore, by configuring the operation member to have a predetermined length in the longitudinal direction, the connection mechanism can be easily operated even if the connection mechanism is disposed at a position where it is difficult to operate manually.

　本発明は、上部施肥機の回動を段階的（所定角度）に行うことができるため、残留肥料の量や排出速度等に合わせて上部施肥機の角度を設定することが可能となる。また、作業者が上部施肥機を支えることなく、上部施肥機の予期せぬ転倒によって、作業者が負傷したり、上部施肥機の分離位置より設置位置への急激な戻りによる施肥装置等破損したりすることを防ぐことができる。 Since the present invention can rotate the upper fertilizer stepwise (predetermined angle), it is possible to set the angle of the upper fertilizer according to the amount of residual fertilizer, the discharge speed, and the like. In addition, without supporting the upper fertilizer, the operator may be injured by the unexpected fall of the upper fertilizer, or the fertilizer may be damaged due to a sudden return from the separation position of the upper fertilizer to the installation position. Can be prevented.
　本発明は、上部施肥機と下部施肥機が分離位置から設置位置に、容易に位置変化可能となる。上部施肥機の重心が、回動支持軸よりも外方に位置した場合でも、安定した保持を確保することができる。 In the present invention, the position of the upper fertilizer and the lower fertilizer can be easily changed from the separation position to the installation position. Even when the center of gravity of the upper fertilizer is positioned outward from the rotation support shaft, stable holding can be ensured.
　本発明は、上部施肥機を上方へ回動した際、選別網は自由に回動し、選別網（のそれぞれ左側端部）とホッパ（のそれぞれ内側）とが離間し隙間が形成されるので、ホッパ内の肥料、特に選別網の下方に残存する肥料をスムースに排出することができる。よって、施肥装置内の肥料の排出及び清掃の効率化を図ることができる。また、選別網は、第二回動支持軸により枢支されているため、上部施肥機の回動時に選別網が外れたり、取り付け位置がずれたりすることがない。 In the present invention, when the upper fertilizer is rotated upward, the sorting net freely rotates, and the sorting net (each left end portion) and the hopper (each inside) are separated to form a gap. The fertilizer in the hopper, particularly the fertilizer remaining below the sorting net can be discharged smoothly. Therefore, the discharge of the fertilizer in the fertilizer application and the efficiency of cleaning can be achieved. Further, since the sorting net is pivotally supported by the second rotation support shaft, the sorting net does not come off or the attachment position is not shifted when the upper fertilizer is turned.

　以下では、図３及び図６から図８までを用いて、連結機構１８０及び解除機構１９０について説明する。 Hereinafter, the connection mechanism 180 and the release mechanism 190 will be described with reference to FIGS. 3 and 6 to 8.
　図６及び図７に示すように、連結機構１８０は、第一入力軸１３２と第二入力軸１４２とを相対回転不能となるように連結するものである。連結機構１８０は、主として第一咬合部材１８１、第二咬合部材１８２、付勢部材１８３等を具備する。
　なお、説明の便宜上、図７においては、第二上部施肥機１４０の第二ホッパ１４３、第一上部施肥機１３０の第一ホッパ１３３、第一把持部１３５等の図示を省略する。 As shown in FIGS. 6 and 7, the connecting mechanism 180 connects the first input shaft 132 and the second input shaft 142 so as not to be relatively rotatable. The coupling mechanism 180 mainly includes a first occlusion member 181, a second occlusion member 182, an urging member 183, and the like.
For convenience of explanation, illustration of the second hopper 143 of the second upper fertilizer applicator 140, the first hopper 133 of the first upper fertilizer applicator 130, the first gripping portion 135, and the like is omitted in FIG.
　第一咬合部材１８１は、第一入力軸１３２の左端部に、第一入力軸１３２と相対回転不能に設けられる。具体的には、第一咬合部材１８１は、スプリングピン１８１ａによって第一入力軸１３２に固設される。第一咬合部材１８１の左端部には、後述する第二咬合部材１８２と咬合可能な爪が形成される。 The first occlusion member 181 is provided at the left end portion of the first input shaft 132 so as not to rotate relative to the first input shaft 132. Specifically, the first occlusion member 181 is fixed to the first input shaft 132 by a spring pin 181a. At the left end of the first occlusion member 181, a nail that can be engaged with a second occlusion member 182 described later is formed.
　第二咬合部材１８２は、第二入力軸１４２の右端部に、第二入力軸１４２の軸線方向に沿って摺動可能に設けられる。第二咬合部材１８２の右端部には、第一咬合部材１８１と咬合可能な爪が形成される。第二咬合部材１８２が右方へと摺動された際に、第二咬合部材１８２の爪と第一咬合部材１８１の爪とが咬合される。 The second occlusion member 182 is provided at the right end portion of the second input shaft 142 so as to be slidable along the axial direction of the second input shaft 142. A claw that can be engaged with the first occlusion member 181 is formed at the right end of the second occlusion member 182. When the second occlusion member 182 is slid rightward, the claws of the second occlusion member 182 and the claws of the first occlusion member 181 are engaged.
　また、第二咬合部材１８２と第一咬合部材１８１とが咬合した際に、第二咬合部材１８２は、第二入力軸１４２と相対回転不能となる。具体的には、第二入力軸１４２に挿通されたスプリングピン１８２ａが、第二咬合部材１８２に形成された溝部１８２ｂと係合することにより、第二咬合部材１８２は、第二入力軸１４２と相対回転不能となる。 In addition, when the second occlusion member 182 and the first occlusion member 181 are engaged, the second occlusion member 182 cannot rotate relative to the second input shaft 142. Specifically, the spring pin 182a inserted through the second input shaft 142 engages with a groove portion 182b formed in the second occlusion member 182 so that the second occlusion member 182 is connected to the second input shaft 142. Relative rotation is impossible.
　付勢部材１８３は、第二咬合部材１８２を右方に向かって付勢するものである。付勢部材１８３は、第二咬合部材１８２と、第二入力軸１４２の中途部（第二咬合部材１８２の左方）に形成されるバネ受け部１４２ａと、の間に配置される。付勢部材１８３は、第二咬合部材１８２を右方、すなわち第一咬合部材１８１と咬合する方向に向かって付勢する。本実施形態に係る付勢部材１８３はコイルバネであるが、本発明はこれに限るものではなく、第二咬合部材１８２を右方に付勢することができるものであればよい。 The biasing member 183 biases the second occlusal member 182 toward the right. The biasing member 183 is disposed between the second occlusion member 182 and a spring receiving portion 142a formed in the middle portion of the second input shaft 142 (leftward of the second occlusion member 182). The urging member 183 urges the second occlusion member 182 to the right, that is, in a direction to engage the first occlusion member 181. The biasing member 183 according to the present embodiment is a coil spring, but the present invention is not limited to this, and any member that can bias the second occlusion member 182 to the right may be used.
　解除機構１９０は、連結機構１８０による第一入力軸１３２と第二入力軸１４２との連結を解除するものである。解除機構１９０は、主として係合部材１９１、操作部材１９２等を具備する。 The release mechanism 190 releases the connection between the first input shaft 132 and the second input shaft 142 by the connection mechanism 180. The release mechanism 190 mainly includes an engagement member 191, an operation member 192, and the like.
　係合部材１９１は、板状の部材が側面視略Ｕ字状に折曲成形された部材である。係合部材１９１は、その両端部によって第二咬合部材１８２を上下から挟むことにより、第二咬合部材１８２と係合する。 The engaging member 191 is a member obtained by bending a plate-like member into a substantially U shape in a side view. The engagement member 191 is engaged with the second occlusion member 182 by sandwiching the second occlusion member 182 from above and below by both ends thereof.
　操作部材１９２は、板状の部材が折曲成形された部材である。操作部材１９２は、所定の長手方向長さを有し、その長手方向が前後方向と略一致するように配置される。操作部材１９２の後端には、係合部材１９１が固設される。操作部材１９２の中途部は、軸線方向を垂直方向とする回動軸１９２ａにより、第二把持部１４５に回動可能に支持される。ここで、前記所定の長手方向長さとは、操作部材１９２の前端部が、オペレータにより容易に把持されることができる程度の長さである。 The operation member 192 is a member obtained by bending a plate-like member. The operating member 192 has a predetermined length in the longitudinal direction, and is arranged so that the longitudinal direction substantially coincides with the front-rear direction. An engagement member 191 is fixed to the rear end of the operation member 192. A midway portion of the operation member 192 is rotatably supported by the second gripping portion 145 by a rotation shaft 192a whose vertical direction is the axial direction. Here, the predetermined length in the longitudinal direction is a length that allows the front end of the operation member 192 to be easily gripped by an operator.
　上述の如く構成された連結機構１８０及び解除機構１９０の動作態様について説明する。 Operation modes of the coupling mechanism 180 and the release mechanism 190 configured as described above will be described.
　まず、図６及び図７を用いて、施肥装置１００が、圃場に肥料を供給する通常の作業状態である場合について説明する。
　この場合、上フレーム１１２にブラケット１１２ａを介して固設される留め具１１２ｂにより、第二把持部１４５のブラケット１４５ａが固定される。これによって、第二上部施肥機１４０の上方回動が規制される。
　また、第二咬合部材１８２は、付勢部材１８３により右方へと付勢される。これによって、第二咬合部材１８２は、第二入力軸１４２に沿って右方へ摺動し、第一咬合部材１８１と咬合する。この状態においては、第一入力軸１３２と第二入力軸１４２とは相対回転不能となるため、エンジン１４から第一入力軸１３２へと伝達された動力は、連結機構１８０を介して第二入力軸１４２へと伝達される。 First, the case where the fertilizer application apparatus 100 is in a normal working state in which fertilizer is supplied to a farm field will be described with reference to FIGS. 6 and 7.
In this case, the bracket 145a of the second gripping portion 145 is fixed by the fastener 112b fixed to the upper frame 112 via the bracket 112a. Thereby, the upward rotation of the second upper fertilizer applicator 140 is restricted.
Further, the second occlusion member 182 is biased rightward by the biasing member 183. Accordingly, the second occlusion member 182 slides rightward along the second input shaft 142 and engages with the first occlusion member 181. In this state, the first input shaft 132 and the second input shaft 142 cannot be rotated relative to each other. Therefore, the power transmitted from the engine 14 to the first input shaft 132 is supplied to the second input via the coupling mechanism 180. Is transmitted to the shaft 142.
　次に、図８を用いて、第一上部施肥機１３０又は第二上部施肥機１４０を上方回動させる場合について説明する。
　この場合、まず、オペレータは、留め具１１２ｂ（図７参照）によるブラケット１４５ａの固定を解除する。
　その後、オペレータは、操作部材１９２の前端部を把持し、当該操作部材１９２を、回動軸１９２ａを中心として平面視時計回りに回動させる。これに伴い、操作部材１９２の後端に固設された係合部材１９１が平面視時計回りに回動される。また、係合部材１９１と係合する第二咬合部材１８２は、付勢部材１８３による付勢力に抗して左方へと摺動する。これによって、連結機構１８０による第一入力軸１３２と第二入力軸１４２との連結が解除される。 Next, the case where the 1st upper fertilizer 130 or the 2nd upper fertilizer 140 is rotated upward is demonstrated using FIG.
In this case, first, the operator releases the fixing of the bracket 145a by the fastener 112b (see FIG. 7).
Thereafter, the operator grasps the front end portion of the operation member 192 and rotates the operation member 192 clockwise around the rotation axis 192a. Accordingly, the engaging member 191 fixed at the rear end of the operation member 192 is rotated clockwise in plan view. The second occlusion member 182 that engages with the engagement member 191 slides to the left against the urging force of the urging member 183. As a result, the connection between the first input shaft 132 and the second input shaft 142 by the connection mechanism 180 is released.
　第一入力軸１３２と第二入力軸１４２との連結が解除された状態で、第一ホッパ１３３及び第二ホッパ１４３に具備される第一把持部１３５又は第二把持部１４５を把持し、上方に持ち上げることによって、第一上部施肥機１３０又は第二上部施肥機１４０を上方に回動させることができる（図３参照）。 In a state where the connection between the first input shaft 132 and the second input shaft 142 is released, the first gripper 135 or the second gripper 145 provided in the first hopper 133 and the second hopper 143 is gripped, and the upper side The first upper fertilizer machine 130 or the second upper fertilizer machine 140 can be rotated upward by lifting up (see FIG. 3).
　上述の如く、第一上部施肥機１３０を上方に回動させることにより、第一上部施肥機１３０内に収容された肥料を、第一ホッパ１３３の連通孔１３３ｂから容易に排出することができる。また、第二上部施肥機１４０を上方に回動させることにより、第二上部施肥機１４０内に収容された肥料を、第二ホッパ１４３の連通孔１４３ｂから容易に排出することができる。これによって、第一上部施肥機１３０及び第二上部施肥機１４０内の清掃等のメンテナンスを容易に行うことができる。 As described above, the fertilizer accommodated in the first upper fertilizer machine 130 can be easily discharged from the communication hole 133b of the first hopper 133 by rotating the first upper fertilizer machine 130 upward. Moreover, the fertilizer accommodated in the 2nd upper fertilizer application 140 can be easily discharged | emitted from the communicating hole 143b of the 2nd hopper 143 by rotating the 2nd upper fertilizer 140 upward. Accordingly, maintenance such as cleaning in the first upper fertilizer applicator 130 and the second upper fertilizer applicator 140 can be easily performed.
　以上の如く、本実施形態に係る施肥装置１００は、
　肥料を収容する第一ホッパ１３３、第一ホッパ１３３の下部に配設され肥料を所定量ずつ繰り出す第一繰り出し部１３６、及び第一繰り出し部１３６に横架され第一繰り出し部１３６にエンジン１４からの動力を伝達する第一入力軸１３２を有する第一上部施肥機１３０と、
　肥料を収容する第二ホッパ１４３、第二ホッパ１４３の下部に配設され肥料を所定量ずつ繰り出す第二繰り出し部１４６、及び第二繰り出し部１４６に第一入力軸１３２と同一軸線上となるように横架され第二繰り出し部１４６にエンジン１４からの動力を伝達する第二入力軸１４２を有する第二上部施肥機１４０と、
　第一繰り出し部１３６及び第二繰り出し部１４６より繰り出される肥料を施肥部１５２近傍まで案内する施肥搬送部１５１を有する下部施肥機１５０と、
　第一上部施肥機１３０、第二上部施肥機１４０、及び下部施肥機１５０を支持する施肥フレーム１１０と、
　施肥フレーム１１０の左右一側において、第一上部施肥機１３０を施肥フレーム１１０に対して上方回動可能に支持する第一回動機構１６０と、
　施肥フレーム１１０の左右他側において、第二上部施肥機１４０を施肥フレーム１１０に対して上方回動可能に支持する第二回動機構１７０と、
　第一入力軸１３２と第二入力軸１４２とを相対回転不能となるように連結する連結機構１８０と、
　連結機構１８０による第一入力軸１３２と第二入力軸１４２との連結を解除する解除機構１９０と、
　を具備するものである。
　このように構成することにより、解除機構１９０により第一入力軸１３２と第二入力軸１４２との連結を容易に解除することができる。これによって、第一上部施肥機１３０及び第二上部施肥機１４０を容易に上方回動させることができ、第一上部施肥機１３０及び第二上部施肥機１４０内の肥料を容易に排出することができる。 As described above, the fertilizer application device 100 according to the present embodiment is

　以下では、図９から図１２を用いて、本発明に係る施肥装置の他の実施形態に係る施肥装置３００について説明する。なお、前述の施肥装置１００と略同一の構成の部材には同一の符号を付し、説明を省略する。また、説明の便宜上、図１０から図１２までにおいては、留め具１１２ｂ等の図示を省略する。
　施肥装置３００が施肥装置１００と異なる点は、解除機構１９０に代えて解除機構２９０を具備する点である。 Below, the fertilizer applying apparatus 300 which concerns on other embodiment of the fertilizer applying apparatus which concerns on this invention is demonstrated using FIGS. 9-12. In addition, the same code | symbol is attached | subjected to the member of the structure substantially the same as the above-mentioned fertilizer application apparatus 100, and description is abbreviate | omitted. For convenience of explanation, the illustration of the fastener 112b and the like is omitted in FIGS.
The difference between the fertilizer application 300 and the fertilizer application 100 is that a release mechanism 290 is provided instead of the release mechanism 190.
　図９及び図１０に示すように、解除機構２９０は、連結機構１８０による第一入力軸１３２と第二入力軸１４２との連結を解除するものである。解除機構２９０は、主として係合部材１９１、操作部材１９２、保持部材２９３等を具備する。 As shown in FIG. 9 and FIG. 10, the release mechanism 290 releases the connection between the first input shaft 132 and the second input shaft 142 by the connection mechanism 180. The release mechanism 290 mainly includes an engagement member 191, an operation member 192, a holding member 293, and the like.
　保持部材２９３は、連結機構１８０による第一入力軸１３２と第二入力軸１４２との連結を解除した状態で保持するものである。保持部材２９３は、主として棒状部材２９３ａ、ブラケット２９３ｂ、付勢部材２９３ｃ、係止部材２９３ｄ等を具備する。 The holding member 293 holds the first input shaft 132 and the second input shaft 142 that are disconnected by the connecting mechanism 180 in a released state. The holding member 293 mainly includes a rod-shaped member 293a, a bracket 293b, a biasing member 293c, a locking member 293d, and the like.
　棒状部材２９３ａは、丸棒の部材を折曲成形して構成された部材である。棒状部材２９３ａは、フック状に形成された上端部（以下、単に「フック部２９３ｅ」と記す）を有する。棒状部材２９３ａの一端（下端）から他端（フック部２９３ｅ側の端部）までの長さ（高さ）は、上フレーム１１２の上面から操作部材１９２の上面までの長さ（高さ）よりも大きくなるように構成される。 The rod-shaped member 293a is a member configured by bending a round bar member. The rod-shaped member 293a has an upper end portion (hereinafter simply referred to as “hook portion 293e”) formed in a hook shape. The length (height) from one end (lower end) to the other end (end on the hook portion 293e side) of the rod-shaped member 293a is greater than the length (height) from the upper surface of the upper frame 112 to the upper surface of the operation member 192. Also configured to be larger.
　ブラケット２９３ｂは、棒状部材２９３ａを上下摺動自在に支持するパイプ状の部材である。ブラケット２９３ｂは、第二把持部１４５の右側面に固設される。 The bracket 293b is a pipe-like member that supports the rod-like member 293a so as to be slidable up and down. The bracket 293b is fixed to the right side surface of the second grip portion 145.
　付勢部材２９３ｃは、棒状部材２９３ａを下方に付勢する部材であり、バネ等で構成される。付勢部材２９３ｃは、ブラケット２９３ｂの下方において棒状部材２９３ａに固設されるバネ受け部２９３ｆと、ブラケット２９３ｂと、の間に配置される。 The urging member 293c is a member that urges the rod-shaped member 293a downward, and is configured by a spring or the like. The biasing member 293c is disposed between the bracket 293b and a spring receiving portion 293f fixed to the rod-like member 293a below the bracket 293b.
　係止部材２９３ｄは、板状の部材に切り欠き部２９３ｇを形成して構成された部材である。係止部材２９３ｄは、操作部材１９２の右側面に固設される。係止部材２９３ｄは、操作部材１９２が平面視時計回りに回動され、連結機構１８０による第一入力軸１３２と第二入力軸１４２との連結が解除された際に、平面視において棒状部材２９３ａのフック部２９３ｅ側の端部と切り欠き部２９３ｇとが略一致する位置に配置される。 The locking member 293d is a member configured by forming a notch 293g in a plate-like member. The locking member 293d is fixed to the right side surface of the operation member 192. The locking member 293d is a rod-shaped member 293a in plan view when the operation member 192 is rotated clockwise in plan view and the connection between the first input shaft 132 and the second input shaft 142 by the connecting mechanism 180 is released. The end portion on the side of the hook portion 293e and the notch portion 293g are disposed at substantially the same position.
　このような構成において、図１０から図１２までを用いて、第一上部施肥機１３０又は第二上部施肥機１４０を上方回動させる場合の動作態様について説明する。 In such a configuration, an operation mode when the first upper fertilizer machine 130 or the second upper fertilizer machine 140 is rotated upward will be described with reference to FIGS. 10 to 12.
　図１１に示すように、操作部材１９２を平面視時計回りに回動させると、連結機構１８０による第一入力軸１３２と第二入力軸１４２との連結が解除される。 As shown in FIG. 11, when the operation member 192 is rotated clockwise in plan view, the connection between the first input shaft 132 and the second input shaft 142 by the connection mechanism 180 is released.
　図１２に示すように、この状態で、第二把持部１４５を持って、上方へと持ち上げると、棒状部材２９３ａの下端が上フレーム１１２の上面から離間し、付勢部材２９３ｃによって棒状部材２９３ａが下方へ摺動される。棒状部材２９３ａが下方へ摺動されると、棒状部材２９３ａのフック部２９３ｅが係止部材２９３ｄの切り欠き部２９３ｇと係合する。これによって、操作部材１９２から手を離しても操作部材１９２を当該位置で保持することができ、ひいては第一入力軸１３２と第二入力軸１４２との連結を解除した状態で保持することができる。 As shown in FIG. 12, in this state, when the second grip 145 is held and lifted upward, the lower end of the bar-shaped member 293a is separated from the upper surface of the upper frame 112, and the bar-shaped member 293a is moved by the urging member 293c. It is slid downward. When the rod-like member 293a is slid downward, the hook portion 293e of the rod-like member 293a engages with the notch portion 293g of the locking member 293d. As a result, the operation member 192 can be held at the position even when the hand is released from the operation member 192. As a result, the connection between the first input shaft 132 and the second input shaft 142 can be held. .
　第一上部施肥機１３０又は第二上部施肥機１４０を上方回動させ、肥料の排出等のメンテナンスを行った後に、第二上部施肥機１４０を元の位置に戻すように下方へ回動すると、棒状部材２９３ａの下端が上フレーム１１２の上面に当接し、棒状部材２９３ａが上方へ摺動される。棒状部材２９３ａが上方へ摺動されると、フック部２９３ｅと切り欠き部２９３ｇとの係合が解除される（図１１参照）。これによって、操作部材１９２が回動可能となり、連結機構１８０により第一入力軸１３２と第二入力軸１４２とが連結される（図１０参照）。 After rotating the first upper fertilizer machine 130 or the second upper fertilizer machine 140 and performing maintenance such as discharge of fertilizer, turning the second upper fertilizer machine 140 downward to return to the original position, The lower end of the rod-shaped member 293a contacts the upper surface of the upper frame 112, and the rod-shaped member 293a is slid upward. When the rod-shaped member 293a is slid upward, the engagement between the hook portion 293e and the notch portion 293g is released (see FIG. 11). As a result, the operation member 192 can be rotated, and the first input shaft 132 and the second input shaft 142 are coupled by the coupling mechanism 180 (see FIG. 10).
　このようにして、第一上部施肥機１３０を下方回動させた後に第二上部施肥機１４０を下方回動させる際には、操作部材１９２が平面視時計回りに回動された状態に保持されているため、第二咬合部材１８２が第一咬合部材１８１に干渉することがなく、損傷や破損等を防止することができる。
　また、保持部材２９３により、第二上部施肥機１４０を上方回動させるだけで、操作部材１９２を平面視時計回りに回動された状態に保持することができる。さらに、第二上部施肥機１４０を下方回動させるだけで、操作部材１９２の保持を解除することができる。これによって、連結機構１８０の連結操作及び連結解除動作の忘れを防止することができる。 In this way, when the second upper fertilizer applicator 140 is rotated downward after the first upper fertilizer applicator 130 is rotated downward, the operation member 192 is held in a state of being rotated clockwise in plan view. Therefore, the second occlusion member 182 does not interfere with the first occlusion member 181, and damage or breakage can be prevented.
Further, the operating member 192 can be held in a state of being rotated clockwise in plan view by simply rotating the second upper fertilizer applicator 140 upward by the holding member 293. Furthermore, the holding of the operation member 192 can be released simply by rotating the second upper fertilizer applicator 140 downward. Thereby, it is possible to prevent forgetting the connection operation and the connection release operation of the connection mechanism 180.
　なお、保持部材２９３の構成は前記構成に限定するものではなく、第一上部施肥機１３０と第二上部施肥機１４０を上方へ回動するときに、操作部材１９２を係止レバーやピン等で係止又は固定し、第一上部施肥機１３０と第二上部施肥機１４０を下方へ回動した後に手動で係止又は固定を解除する構成とすることも可能である。 The configuration of the holding member 293 is not limited to the above configuration, and when the first upper fertilizer 130 and the second upper fertilizer 140 are rotated upward, the operation member 192 is locked with a locking lever, a pin, or the like. It is also possible to adopt a configuration in which the locking or fixing is manually performed after the first upper fertilizer 130 and the second upper fertilizer 140 are pivoted downward after being locked or fixed.
　以上の如く、本実施形態に係る解除機構２９０は、
　連結機構１８０による第一入力軸１３２と第二入力軸１４２との連結を解除した状態で保持する保持部材２９３を具備するものである。
　このように構成することにより、連結機構１８０による第一入力軸１３２と第二入力軸１４２との連結を解除した状態に保持することができる。これによって、第一上部施肥機１３０又は第二上部施肥機１４０を回動させる際の、第一咬合部材１８１と第二咬合部材１８２との干渉を防止することができ、ひいては連結機構１８０の破損を防止することができる。 As described above, the release mechanism 290 according to this embodiment is
A holding member 293 that holds the first input shaft 132 and the second input shaft 142 in a state in which the connection mechanism 180 releases the connection is provided.
With this configuration, the connection between the first input shaft 132 and the second input shaft 142 by the connection mechanism 180 can be held in a released state. Thereby, when rotating the 1st upper fertilizer machine 130 or the 2nd upper fertilizer machine 140, interference with the 1st occlusion member 181 and the 2nd occlusion member 182 can be prevented, and breakage of connection mechanism 180 by extension Can be prevented.
　また、本発明は、以下に説明するような施肥装置に応用することも可能である。 Further, the present invention can also be applied to a fertilizer application apparatus as described below.
　従来の施肥機においては、施肥機を側方へスライドさせて排出口から残留肥料を排出できるようにしているが、施肥装置毎に設けた排出口より排出する必要があるため、面倒な排出作業となっていた。
　そこで、施肥後に不要となった肥料を施肥装置から容易に取出すことができ、メンテナンス及び清掃作業が効率良く行える施肥装置を提供する。 In conventional fertilizer applicators, the fertilizer can be slid to the side so that residual fertilizer can be discharged from the discharge port. It was.
Then, the fertilizer which can take out the fertilizer which became unnecessary after fertilization easily from a fertilizer, and can perform a maintenance and cleaning work efficiently is provided.
　即ち、肥料を収容するホッパと、該ホッパの下部に配設され肥料を所定量ずつ繰出す繰り出し部とを有する上部施肥機と、前記繰り出し部より繰出される肥料を施肥部近傍まで案内する施肥搬送部を有する下部施肥機と、前記上部施肥機と前記下部施肥機を支持する施肥フレームと、前記上部施肥機の左右一側に設けられる回動支持軸を枢支する枢支ブラケットと、前記回動支持軸または前記施肥フレームの何れか一方に固定される複数の爪を有する爪体と、前記回動支持軸または前記施肥フレームの何れか他方に取付けられて前記爪体と係合可能とされる係止部材と、から成る係止機構を備え、上部施肥機を係止機構により所定角度で保持可能とするものである。 That is, an upper fertilizer that includes a hopper that stores fertilizer, a feeding portion that is disposed below the hopper and feeds the fertilizer by a predetermined amount, and a fertilizer that guides the fertilizer fed from the feeding portion to the vicinity of the fertilizer. A lower fertilizer having a conveying section; a fertilizer frame that supports the upper fertilizer and the lower fertilizer; a pivot bracket that pivotally supports a pivot support shaft provided on one side of the upper fertilizer; A claw body having a plurality of claws fixed to either the rotation support shaft or the fertilization frame, and attached to either the rotation support shaft or the fertilization frame and engageable with the claw body. The upper fertilizer can be held at a predetermined angle by the locking mechanism.
　このように構成することにより、上部施肥機の回動を段階的（所定角度）に行うことができるため、残留肥料の量や排出速度等に合わせて上部施肥機の角度を設定することが可能となる。また、作業者が上部施肥機を支えることなく、上部施肥機の予期せぬ転倒によって、作業者が負傷したり、上部施肥機の分離位置より設置位置への急激な戻りによる施肥装置等破損したりすることを防ぐことができる。 By configuring in this way, the upper fertilizer can be rotated stepwise (predetermined angle), so it is possible to set the angle of the upper fertilizer according to the amount of remaining fertilizer, the discharge speed, etc. It becomes. In addition, without supporting the upper fertilizer, the operator may be injured by the unexpected fall of the upper fertilizer, or the fertilizer may be damaged due to a sudden return from the separation position of the upper fertilizer to the installation position. Can be prevented.
　また、前記係止部材は、レバーの一端に係止爪を形成し、他端に係止部材を係止方向に付勢する付勢部材の取付部と操作部を形成し、中央部に係止部材を回動自在に枢支する枢支部を形成するものである。 Further, the locking member forms a locking claw at one end of the lever, and forms an attaching portion and an operating portion of a biasing member for biasing the locking member in the locking direction at the other end, and is engaged at the center portion. A pivotal support part for pivotally supporting the stop member is formed.
　このように構成することにより、上部施肥機と下部施肥機が分離位置から設置位置に、容易に位置変化可能となる。上部施肥機の重心が、回動支持軸よりも外方に位置した場合でも、安定した保持を確保することができる。 This configuration makes it possible to easily change the position of the upper fertilizer and the lower fertilizer from the separation position to the installation position. Even when the center of gravity of the upper fertilizer is positioned outward from the rotation support shaft, stable holding can be ensured.
　次に、図１３から図１８までを用いて、実施の形態を説明する。 Next, an embodiment will be described with reference to FIGS.
　以下では、図１３から図１８までを用いて、第一上部施肥機１３０、第二上部施肥機１４０の係止機構２００・２００について説明する。 Hereinafter, the locking mechanisms 200 and 200 of the first upper fertilizer machine 130 and the second upper fertilizer machine 140 will be described with reference to FIGS. 13 to 18.
　本実施例の施肥装置１００の位置は、「接続位置」と「分離位置」とに大きく分けられる。
　前者の「接続位置」とは、第一上部施肥機１３０（第二上部施肥機１４０）と、下部施肥機１５０とが接続され施肥可能な位置を意味する。例えば、施肥装置１００が施肥を行う時や、田植機１が倉庫に格納される時等の状態である。
　また、後者の「分離位置」とは、第一上部施肥機１３０（第二上部施肥機１４０）が、第一回動支持軸１６２（第二回動支持軸１７２）を中心に機体外側方へと回動し、機体外側へと第一上部施肥機１３０（第二上部施肥機１４０）が下部施肥機１５０と離れた位置を意味する。例えば、田植機１を収納する前に、第一ホッパ１３３・１３３（第二ホッパ１４３・１４３）内の肥料を取出す時に、肥料を取出し易いように機体外側方に第一上部施肥機１３０（第二上部施肥機１４０）を移動させた時等である。 The position of the fertilizer application apparatus 100 according to the present embodiment is roughly divided into a “connection position” and a “separation position”.
The former “connection position” means a position where the first upper fertilizer 130 (second upper fertilizer 140) and the lower fertilizer 150 can be connected and fertilized. For example, it is a state when the fertilizer application apparatus 100 performs fertilization or when the rice transplanter 1 is stored in a warehouse.
Further, the latter “separation position” means that the first upper fertilizer machine 130 (second upper fertilizer machine 140) moves outward from the airframe around the first rotation support shaft 162 (second rotation support shaft 172). It means that the first upper fertilizer machine 130 (second upper fertilizer machine 140) is separated from the lower fertilizer machine 150 toward the outside of the machine body. For example, when the fertilizer in the first hoppers 133 and 133 (second hoppers 143 and 143) is taken out before the rice transplanter 1 is stored, the first upper fertilizer machine 130 (first For example, when the second upper fertilizer applicator 140) is moved.
　第二上部施肥機１４０は、その側方に送風機１５３ａが配設されている。その為、第二上部施肥機１４０と下部施肥機１５０を分離位置にする場合、進行方向左側にある送風機１５３ａは、前方へと回動し退避させる。つまり図１３に示すように、送風機回動軸１５３ｃ・１５３ｃを中心に、送風機１５３ａ全体を前方へと回動させることで、支持板１１１前方へ送風機１５３ａを退避させ、第二上部施肥機１４０側方に空間を形成させる。よって、第二上部施肥機１４０が機体側方へ回動した際に、送風機１５３ａと接触することなく第二上部施肥機１４０が回動することができる。 The second upper fertilizer applicator 140 is provided with a blower 153a on its side. Therefore, when the 2nd upper fertilizer 140 and the lower fertilizer 150 are made into a separation position, the air blower 153a on the left side in the traveling direction is rotated forward and retracted. That is, as shown in FIG. 13, by rotating the entire blower 153a forward about the blower rotation shafts 153c and 153c, the blower 153a is retracted forward of the support plate 111, and the second upper fertilizer application 140 side. To form a space. Therefore, when the 2nd upper fertilizer 140 rotates to the body side, the 2nd upper fertilizer 140 can rotate, without contacting blower 153a.
　「接続位置」より「分離位置」へと施肥装置１００の位置を変えるには、作業者は先ず、解除機構１９０によって第一入力軸１３２と第二入力軸１４２との連結を解除する。次に、機体右側の第一把持部１３５を把持しながら、第一回動支持軸１６２を中心に、第一上部施肥機１３０を右外方へと回動させる。よって、作業者には、第一上部施肥機１３０の自重や、第一ホッパ１３３・１３３内の肥料の重量等を支える力を要する。また、作業者の所望位置（角度）に、第一上部施肥機１３０を静止させることは、さらに相当の力を要する。
　よって、以下の係止機構２００を第一回動支持軸１６２及び第二回動支持軸１７２付近に配設することで第一上部施肥機１３０（第二上部施肥機１４０）を上方へ回動したときにその途中の角度で保持可能とする。 In order to change the position of the fertilizer application device 100 from the “connection position” to the “separation position”, the operator first releases the connection between the first input shaft 132 and the second input shaft 142 by the release mechanism 190. Next, the first upper fertilizer applicator 130 is rotated rightward about the first rotation support shaft 162 while gripping the first grip 135 on the right side of the machine body. Therefore, the operator needs a force that supports the weight of the first upper fertilizer applicator 130, the weight of the fertilizer in the first hoppers 133 and 133, and the like. Moreover, it takes a considerable force to make the first upper fertilizer machine 130 stationary at the operator's desired position (angle).
Therefore, the first upper fertilizer applicator 130 (second upper fertilizer applicator 140) is rotated upward by disposing the following locking mechanism 200 in the vicinity of the first rotation support shaft 162 and the second rotation support shaft 172. It is possible to hold it at an angle in the middle.
　以下に詳説する係止機構２００・２００は、本実施例において機体左右側に配設され、左右対称であるので、進行方向左側の係止機構２００の説明は省略する。 Since the locking mechanisms 200 and 200 described in detail below are arranged on the left and right sides of the machine body in the present embodiment and are symmetric, the description of the locking mechanism 200 on the left side in the traveling direction is omitted.
　係止機構２００は、作業者が第一上部施肥機１３０を機体外側方へと回動させる際、所望位置（角度）に段階的に第一上部施肥機１３０を係止するための機構である。
　本実施例において、係止機構２００は、第一回動支持軸１６２付近に配設され、主に、爪体２０１、係止部材２０２、付勢部材２０３、受部材２０４等によって構成されている。 The locking mechanism 200 is a mechanism for locking the first upper fertilizer applicator stepwise at a desired position (angle) when the operator rotates the first upper fertilizer applicator 130 outward. .
In the present embodiment, the locking mechanism 200 is disposed in the vicinity of the first rotation support shaft 162, and mainly includes a claw body 201, a locking member 202, a biasing member 203, a receiving member 204, and the like. .
　図１６に示すように、爪体２０１は、後述する係止部材２０２と係合しつつ第一上部施肥機１３０の回動角度決めを行う部材であり、爪体２０１は第一枢支ブラケット１６１前方（または後方）の第一回動支持軸１６２の前端部上に固設される。つまり、爪体２０１は第一回動支持軸１６２を介して第一枢支ブラケット１６１と一体的に固定され共に回動される。図１６に示すように、爪体２０１は外周に爪２０１ａを所定間隔をあけて形成され、中心部に第一回動支持軸１６２が固設される。該爪体２０１は本実施例では、半円板状であって、外周部２０１ｂに鋸歯状の爪２０１ａ・２０１ａ・・・が複数形成されている。この爪２０１ａ・２０１ａの数だけ段階的に回動することが可能である。
　爪体２０１近傍の支持板１１１には、機体内方へと爪２０１ａが移動することができる開口部１１１ａが開口されている。 As shown in FIG. 16, the claw body 201 is a member that determines the rotation angle of the first upper fertilizer applicator 130 while engaging with a locking member 202 described later. The claw body 201 is a first pivot bracket 161. It is fixed on the front end portion of the front (or rear) first rotation support shaft 162. That is, the claw body 201 is fixed integrally with the first pivot support bracket 161 via the first rotation support shaft 162 and rotated together. As shown in FIG. 16, the claw body 201 is formed with a claw 201a at a predetermined interval on the outer periphery, and a first rotation support shaft 162 is fixed at the center. In this embodiment, the claw body 201 has a semicircular disk shape, and a plurality of sawtooth claw 201a, 201a,. It is possible to rotate stepwise by the number of the claws 201a and 201a.
The support plate 111 in the vicinity of the nail body 201 has an opening 111a through which the nail 201a can move toward the inside of the machine body.
　一方、図１５から図１８のいずれかに示すように、係止部材２０２は、正面視略Ｌ字状に形成されてレバーとし、レバーの中央（Ｌ字の角にあたる箇所）が後述する受部材２０４の回転軸２０４ｃに回転自在に支持される。
　係止部材２０２の一端は、前記爪２０１ａに係合するように、下方に突出した爪状の係止爪２０２ａが形成されている。こうしてラチェットの如く形成されている。係止部材２０２の他端は、後述する付勢部材２０３を取付可能とするため、下方に突出する取付部２０２ｂを備えている。取付部２０２ｂの上方には、作業者が押圧して解除操作し易いように側面視逆Ｌ字状に後方へと屈曲された操作部２０２ｃが形成される。 On the other hand, as shown in any of FIGS. 15 to 18, the locking member 202 is formed in a substantially L shape in front view to serve as a lever, and a receiving member whose center (the portion corresponding to the corner of the L shape) is described later. A rotary shaft 204c of 204 is rotatably supported.
One end of the locking member 202 is formed with a claw-shaped locking claw 202a protruding downward so as to engage with the claw 201a. Thus, it is formed like a ratchet. The other end of the locking member 202 is provided with a mounting portion 202b that protrudes downward so that a biasing member 203 described later can be mounted. Above the attachment portion 202b, an operation portion 202c is formed that is bent backward in an inverted L shape in a side view so that the operator can easily press and release it.
　受部材２０４は、係止部材２０２を支持すると共に、後述する付勢部材２０３を受ける部材であって、爪体２０１後方の支持板１１１の機体内側に取付けられている。詳しくは、支持板１１１に対し、板状の受部材２０４は垂直に固設され、支持板１１１よりも上方に突出するように上部２０４ａが形成されている。上部２０４ａには前方に突出するように回転軸２０４ｃが固設される。また、受部材２０４の下部には、機体内側斜め上方に突出するように傾斜部２０４ｂが形成されている。 The receiving member 204 is a member that supports the locking member 202 and receives an urging member 203 described later, and is attached to the inside of the body of the support plate 111 behind the claw body 201. Specifically, the plate-shaped receiving member 204 is fixed vertically to the support plate 111, and an upper portion 204 a is formed so as to protrude above the support plate 111. A rotation shaft 204c is fixed to the upper portion 204a so as to protrude forward. In addition, an inclined portion 204b is formed at a lower portion of the receiving member 204 so as to protrude obliquely upward on the inner side of the machine body.
　付勢部材２０３は、コイルバネ等の弾性部材で構成され、係止部材２０２を付勢する役割を果たし、係止部材２０２の取付部２０２ｂと受部材２０４の傾斜部２０４ｂとに嵌合される。つまり、付勢部材２０３は、回転軸２０４ｃを中心に係止部材２０２の操作部２０２ｃ側を上方へと付勢している。なお、操作部２０２ｃを付勢部材により上方へ引っ張ったり、係止爪２０２ａ側を機体内方向へ引っ張ったり、付勢部材２０３は捩じりバネによって構成して、該捩じりバネを回転軸２０４ｃに外嵌して受部材２０４と係止部材２０２の間に介装して、係止部材２０２の係止爪２０２ａが爪２０１ａに係止するように付勢する構成としたりすることも可能であり、付勢部材２０３の構造及び配置は限定するものではない。よって、付勢部材２０３は回転軸２０４ｃを中心に係止部材２０２の係止爪２０２ａ側を下方へと付勢することとなり、係止爪２０２ａと爪２０１ａとが係合される。
　こうして、第一上部施肥機１３０を機体外方へ回動した際、係止爪２０２ａが爪２０１ａと係合し、第一上部施肥機１３０がその重量により下方へ回動しようとしても係止爪２０２ａと爪２０１ａとの係合によりその回動位置が保持されるのである。 The urging member 203 is composed of an elastic member such as a coil spring, and serves to urge the locking member 202 and is fitted to the mounting portion 202b of the locking member 202 and the inclined portion 204b of the receiving member 204. That is, the urging member 203 urges the operating portion 202c side of the locking member 202 upward about the rotation shaft 204c. The operating portion 202c is pulled upward by the urging member, the locking claw 202a side is pulled in the direction of the machine body, the urging member 203 is constituted by a torsion spring, and the torsion spring is rotated by the rotating shaft. It is also possible to adopt a configuration in which the engaging claw 202a of the engaging member 202 is urged so as to be engaged with the claw 201a by being externally fitted to the receiving member 204c and interposed between the receiving member 204 and the engaging member 202. The structure and arrangement of the urging member 203 are not limited. Therefore, the urging member 203 urges the locking claw 202a side of the locking member 202 around the rotation shaft 204c, and the locking claw 202a and the claw 201a are engaged.
Thus, when the first upper fertilizer machine 130 is rotated outward, the locking claw 202a engages with the claw 201a, and the first upper fertilizer machine 130 is locked even if it attempts to rotate downward due to its weight. The rotation position is held by the engagement between 202a and the claw 201a.
　次に、ホッパ内の残留肥料を排出する場合やメンテナンス等で、第一上部施肥機１３０を上昇させた時の具体的な動きを説明する。まず、図１３に示す前記解除機構１９０を操作して連結機構１８０における第一入力軸１３２と第二入力軸１４２間の連結を解除し、作業者が第一把持部１３５を持って持ち上げる。すると、図１６に示す第一上部施肥機１３０と下部施肥機１５０との接続位置から、図１７に示す第一回動支持軸１６２を中心に第一上部施肥機１３０が機体外方（上方）へと回動する。そして、第一回動支持軸１６２上の爪体２０１が第一回動支持軸１６２の動きと共に、付勢部材２０３の付勢力に抗して、爪２０１ａが係止爪２０２ａ内側外周に沿うように回転し、係止爪２０２ａと爪２０１ａが係合する状態となる。
　この状態で、作業者が第一把持部１３５（図１３参照）より手を離した場合等、係止爪２０２ａが爪２０１ａに係止されているので、第一上部施肥機１３０はその回動位置を保持できる。この場合、第一上部施肥機１３０に大量の肥料が残っておりその肥料を排出する場合等で、小さな傾斜角度に保持できる。そして、残留肥料が少ないほど大きく回動し、第一上部施肥機１３０はその回動に応じて段階的（本実施例では爪２０１ａが四箇所あるので四段階）に停止可能となる。こうしてそれ以上第一上部施肥機１３０が、機体内方へ回動することを防ぎ、第一上部施肥機１３０が急激に接続位置へ戻ってしまう恐れをなくすことができる。 Next, a specific movement when the first upper fertilizer applicator 130 is raised in the case of discharging the residual fertilizer in the hopper or in maintenance will be described. First, the release mechanism 190 shown in FIG. 13 is operated to release the connection between the first input shaft 132 and the second input shaft 142 in the connection mechanism 180, and the operator holds the first grip portion 135 and lifts it up. Then, from the connection position of the first upper fertilizer 130 and the lower fertilizer 150 shown in FIG. 16, the first upper fertilizer 130 is outward (upward) around the first rotation support shaft 162 shown in FIG. 17. Rotate to. And the nail | claw body 201 on the 1st rotation support shaft 162 resists the urging | biasing force of the urging | biasing member 203 with the movement of the 1st rotation support shaft 162, and the nail | claw 201a follows the inner periphery of the latching claw 202a. And the locking claw 202a and the claw 201a are engaged.
In this state, when the operator removes his / her hand from the first gripping part 135 (see FIG. 13) and the like, the locking claw 202a is locked to the claw 201a. Can hold position. In this case, when a large amount of fertilizer remains in the first upper fertilizer applicator 130 and the fertilizer is discharged, it can be held at a small inclination angle. Then, the smaller the residual fertilizer, the larger the rotation, and the first upper fertilizer machine 130 can be stopped in a stepwise manner (four steps because there are four claws 201a in this embodiment). In this way, it is possible to prevent the first upper fertilizer machine 130 from rotating further toward the inside of the machine body and eliminate the possibility that the first upper fertilizer machine 130 suddenly returns to the connection position.
　そして第一上部施肥機１３０を機体外方へ最大回動させると、図１８に示すように、爪体２０１の端部が支持板１１１の外側面と当接し、それ以上、第一上部施肥機１３０が外方（下方）に回動することができなく、また、第一上部施肥機１３０の重心は第一回動支持軸１６２よりも外側（支点越え）に位置しているため、その状態が保持される。 Then, when the first upper fertilizer 130 is rotated to the maximum outside the body, as shown in FIG. 18, the end portion of the claw body 201 comes into contact with the outer surface of the support plate 111, and the first upper fertilizer is further increased. 130 cannot rotate outward (downward), and the center of gravity of the first upper fertilizer applicator 130 is located outside (over the fulcrum) of the first rotation support shaft 162, so that state Is retained.
　図１７、図１８に示す分離位置から図１６に示す接続位置へと第一上部施肥機１３０を移動（回動）させる際には、作業者は、操作部２０２ｃを下方へと押圧する。操作部２０２ｃを下方へと押圧することで、付勢部材２０３の付勢力に抗して、回転軸２０４ｃを中心に操作部２０２ｃが下方に回動し、係止爪２０２ａが上方へと回動し、係止爪２０２ａと爪２０１ａとの係合関係が解消される。その状態で、第一上部施肥機１３０を機体中央へと回動させて、下部施肥機１５０と接合することで、図１６に示す設置位置へと戻すことが可能な構成となっている。 When moving (turning) the first upper fertilizer applicator 130 from the separation position shown in FIGS. 17 and 18 to the connection position shown in FIG. 16, the operator presses the operation unit 202c downward. By pressing the operating portion 202c downward, the operating portion 202c rotates downward about the rotation shaft 204c against the urging force of the urging member 203, and the locking claw 202a rotates upward. Then, the engagement relationship between the locking claw 202a and the claw 201a is canceled. In this state, the first upper fertilizer applicator 130 is rotated to the center of the machine body and joined to the lower fertilizer applicator 150 to return to the installation position shown in FIG.
　上記構成において、第一回動支持軸１６２（第二回動支持軸１７２）に爪体２０１を固設し、施肥フレーム１１０の支持板１１１に受部材２０４を介して、係止部材２０２を配置した。しかし、第一回転支持軸１６２（第二回動支持軸１７２）に固設し、施肥フレーム１１０に受部材２０４を介して、爪体２０１を配置してもよく限定するものではない。 In the above configuration, the claw body 201 is fixed to the first rotation support shaft 162 (second rotation support shaft 172), and the locking member 202 is disposed on the support plate 111 of the fertilization frame 110 via the receiving member 204. did. However, the claw body 201 may be arranged on the first rotation support shaft 162 (second rotation support shaft 172) and the fertilizer frame 110 with the receiving member 204 interposed therebetween.
　以上の如く、本実施形態に係る施肥装置１００は、肥料を収容するホッパ１３３・１４３と、該ホッパ１３３・１４３の下部に配設され肥料を所定量ずつ繰出す繰り出し部１３６・１４６を有する上部施肥機１３０・１４０と、前記繰り出し部１３６・１４６より繰出される肥料を施肥部１５２近傍まで案内する施肥搬送部１５１を有する下部施肥機１５０と、前記上部施肥機１３０と前記下部施肥機１５０を支持する施肥フレーム１１０と、前記上部施肥機１３０の左右一側に設けられる回動支持軸１６２・１７２を枢支する枢支ブラケット１６１・１７１と、前記回動支持軸１６２・１７２または前記施肥フレーム１１０の何れか一方に固定される複数の爪２０１ａを有する爪体２０１と、前記回動支持軸１６２・１７２または前記施肥フレーム１１０の何れか他方に取付けられて前記爪体２０１と係合可能とされる係止部材２０２とから成る係止機構２００を備え、上部施肥機１３０を係止機構２００により所定角度で保持可能とする。 As described above, the fertilizer application device 100 according to the present embodiment includes the hoppers 133 and 143 that store the fertilizer, and the upper portions that are disposed below the hoppers 133 and 143 and that feed out the fertilizers by a predetermined amount. A fertilizer applicator 130, 140, a lower fertilizer applicator 150 having a fertilizer transporting part 151 for guiding fertilizer fed from the feeding parts 136, 146 to the vicinity of the fertilizer applying part 152, the upper fertilizer applicator 130, and the lower fertilizer applicator 150. The supporting fertilizer frame 110, the pivot brackets 161 and 171 pivotally supporting the pivot support shafts 162 and 172 provided on the left and right sides of the upper fertilizer machine 130, and the pivot support shafts 162 and 172 or the fertilizer frame. 110, a claw body 201 having a plurality of claws 201a fixed to one of the rotation support shafts 162 and 172, or the application A locking mechanism 200 is provided that includes a locking member 202 that is attached to either one of the frames 110 and can be engaged with the claw body 201. The upper fertilizer applicator 130 can be held at a predetermined angle by the locking mechanism 200. And
　このように構成することにより、上部施肥機１３０・１４０の回動を段階的（所定角度）に行うことができる。また、作業者が上部施肥機１３０を支えることなく、上部施肥機１３０の予期せぬ転倒によって、作業者が負傷したり、分離位置より接続位置への急激な戻りによる施肥装置１００等の破損をしたりすることを防ぐことができる。 </ RTI> By configuring in this way, the upper fertilizers 130 and 140 can be rotated stepwise (predetermined angle). Also, without supporting the upper fertilizer machine 130 by an operator, an unexpected fall of the upper fertilizer machine 130 may injure the worker or damage the fertilizer 100 or the like due to a sudden return from the separation position to the connection position. Can be prevented.
　よって、前記係止部材２０２は、レバーの一端に係止爪２０２ａを形成し、他端に係止部材２０２を係止方向に付勢する付勢部材２０３の取付部２０２ｂと操作部２０２ｃを形成し、中央部に係止部材２０２を回動自在に枢支する枢支部を形成する。 Therefore, the locking member 202 forms a locking claw 202a at one end of the lever, and forms an attachment portion 202b and an operation portion 202c of the biasing member 203 that biases the locking member 202 in the locking direction at the other end. And the pivot part which pivotably supports the locking member 202 in the center part is formed.
　このように構成することにより、施肥機回動状態から施肥機設置状態に、容易に状態変化可能となり、上部施肥機１３０・１４０の重心が、回動支持軸１６２・１７２よりも外方へと位置した場合でも、安定性を備えた施肥装置１００の構造となる。 By comprising in this way, a state change is easily possible from a fertilizer rotation state to a fertilizer installation state, and the gravity center of the upper fertilizer machines 130 and 140 moves outward rather than the rotation support shafts 162 and 172. Even if it is located, the structure of the fertilizer application device 100 having stability is obtained.
　また、本発明は、以下に説明するような施肥装置に応用することも可能である。 Further, the present invention can also be applied to a fertilizer application apparatus as described below.
　従来、乗用田植機等の作業機械に具備され、圃場に施肥する施肥装置において、前記施肥装置のホッパ内に目の粗い網体を水平に嵌着する技術が公知となっている。このように構成すると、湿気を吸収して固まった肥料塊が繰出機構に流下するのを阻止するとともに、ブリッジ現象によって肥料の流下が妨げられるのも防止することができる。
　しかしながら、ホッパ内には前記網体が嵌着されており、また、前記ホッパは繰出機構の上部に上向きに開口部を設けて取り付けられるので、施肥作業終了後に残った肥料を作業者が施肥装置内の肥料の排出及び清掃を行うことは困難である。 2. Description of the Related Art Conventionally, a technique for horizontally fitting a coarse mesh body in a hopper of a fertilizer application device that is provided in a work machine such as a riding rice transplanter and fertilizes in a farm field is known. With this configuration, it is possible to prevent the fertilizer lump solidified by absorbing moisture from flowing down to the feeding mechanism and to prevent the flow of fertilizer from being hindered by the bridge phenomenon.
However, the mesh body is fitted in the hopper, and the hopper is mounted with an opening upward in the upper part of the feeding mechanism, so that the fertilizer remaining after the fertilization operation is completed by the operator. It is difficult to discharge and clean the fertilizer inside.
　そこで、前記施肥装置を作業姿勢とメンテナンス姿勢とに切り換え可能に構成する技術が公知となっている。このように構成すると、前記ホッパ及び繰出機構を上方に回動させることにより、前記ホッパ内部に収容された肥料を容易に排出させることができる。
　しかしながら、前記施肥装置のホッパ内に前記網体が嵌着された構造の場合、その網体により排出が阻害されて少し残り、これらをすべて排出するには網体を取り外す必要があり、排出作業に手間がかかっていた。 Therefore, a technique is known in which the fertilizer application is configured to be switchable between a working posture and a maintenance posture. If comprised in this way, the fertilizer accommodated in the said hopper can be easily discharged | emitted by rotating the said hopper and feeding mechanism upwards.
However, in the case of the structure in which the net body is fitted in the hopper of the fertilizer application, the net body is obstructed to discharge a little, and it is necessary to remove the net body in order to discharge all of these, and the discharging work It took time and effort.
　そこで、施肥装置内の肥料の排出及び清掃の効率化を図ることが可能な施肥装置を提供する。 Therefore, a fertilizer application apparatus capable of improving the efficiency of discharging and cleaning fertilizer in the fertilizer application apparatus is provided.
　即ち、肥料を収容するホッパ及び前記ホッパの下部に配設され肥料を所定量ずつ繰り出す繰り出し部を有する上部施肥機と、前記繰り出し部より繰り出される肥料を施肥部近傍まで案内する施肥搬送部を有する下部施肥機と、前記上部施肥機及び前記下部施肥機を支持する施肥フレームと、前記上部施肥機の左右一側において、前記上部施肥機を前記施肥フレームに対して上方回動可能に枢支する第一回動支持軸と、前記ホッパの内部に配設され、前記ホッパに収容される肥料のうち所定の大きさ以下の肥料のみを前記繰り出し部へと通過させる選別網と、前記第一回動支持軸と左右反対側の前記選別網端を、前記ホッパ内部で上方回動可能に枢支する選別網回動支持軸と、を具備するものである。 That is, it has a hopper that stores fertilizer, an upper fertilizer that is disposed in the lower portion of the hopper and has a feeding portion that feeds the fertilizer by a predetermined amount, and a fertilizer transporting portion that guides the fertilizer fed from the feeding portion to the vicinity of the fertilizer. The lower fertilizer, the fertilizer frame that supports the upper fertilizer and the lower fertilizer, and the left and right sides of the upper fertilizer are pivotally supported so that the upper fertilizer can be rotated upward with respect to the fertilizer frame. A first rotation support shaft, a sorting net disposed inside the hopper and passing only fertilizers of a predetermined size or less among the fertilizers stored in the hopper to the feeding portion; And a sorting screen rotation support shaft that pivotally supports the sorting screen end on the opposite side to the moving support shaft so as to be capable of rotating upward within the hopper.
　このように構成することにより、上部施肥機を上方へ回動した際、選別網は自由に回動し、選別網（のそれぞれ左側端部）とホッパ（のそれぞれ内側）とが離間し隙間が形成されるので、ホッパ内の肥料、特に選別網の下方に残存する肥料をスムースに排出することができる。よって、施肥装置内の肥料の排出及び清掃の効率化を図ることができる。また、選別網は、選別網回動支持軸により枢支されているため、上部施肥機の回動時に選別網が外れたり、取り付け位置がずれたりすることがない。 With this configuration, when the upper fertilizer is rotated upward, the sorting net freely rotates, the sorting net (each left end portion) and the hopper (each inner side) are separated, and a gap is formed. Since it is formed, the fertilizer in the hopper, in particular, the fertilizer remaining below the sorting net can be discharged smoothly. Therefore, the discharge of the fertilizer in the fertilizer application and the efficiency of cleaning can be achieved. Further, since the sorting net is pivotally supported by the sorting net rotating support shaft, the sorting net does not come off or the mounting position is not shifted when the upper fertilizer is rotated.
　また、前記選別網は左右に分割され、前記選別網回動支持軸は、前記左右に分割された選別網のうち前記第一回動支持軸に最も近接する側の選別網を枢支するものである。 The sorting screen is divided into left and right, and the sorting screen rotation support shaft pivotally supports the sorting screen closest to the first rotation support shaft among the sorting screen divided into the left and right. It is.
　このように構成することにより、上部施肥機を上方へ回動した際、（分割された選別網のうち第一回動支持軸に最も近接する側の）選別網は自由に回動し、前記選別網とホッパとが離間し隙間が形成されるので、前記ホッパ内の肥料、特に前記選別網の下方に残存する肥料をスムースに排出することができる。また、前記ホッパ内の肥料を排出するために回動させることが必要な前記選別網のみを回動可能に構成することにより、前記選別網の回動が肥料の排出を阻害することを防止することができる。よって、施肥装置内の肥料の排出及び清掃の効率化を図ることができる。 By configuring in this way, when the upper fertilizer is rotated upward, the sorting net (on the side of the divided sorting net closest to the first rotation support shaft) freely rotates, Since the sorting net and the hopper are separated from each other and a gap is formed, the fertilizer in the hopper, in particular, the fertilizer remaining below the sorting net can be discharged smoothly. In addition, by rotating only the sorting screen that needs to be rotated to discharge the fertilizer in the hopper, the rotation of the sorting screen prevents the fertilizer from being discharged. be able to. Therefore, the discharge of the fertilizer in the fertilizer application and the efficiency of cleaning can be achieved.
　また、前記選別網の上方回動角度を所定の角度において規制する規制部材を具備するものである。 Further, a regulating member that regulates the upward rotation angle of the sorting net at a predetermined angle is provided.
　このように構成することにより、上部施肥機を上方へ回動した際、選別網とホッパとの隙間の距離を予め設定することができるので、前記選別網が必要以上に回動することがなく、上側のホッパ内から落下する肥料の排出を阻害することを防止できる。よって、施肥装置内の肥料の排出及び清掃の効率化を図ることができる。 With this configuration, when the upper fertilizer is rotated upward, the distance between the sorting net and the hopper can be set in advance, so that the sorting net does not rotate more than necessary. It is possible to prevent the discharge of the fertilizer falling from the upper hopper. Therefore, the discharge of the fertilizer in the fertilizer application and the efficiency of cleaning can be achieved.
　次に、図１９から図２１までを用いて、実施の形態を説明する。 Next, an embodiment will be described with reference to FIGS.
　以下では、図１９を用いて、第一ホッパ１３３・１３３の内部にそれぞれ具備される選別網２３０・２３０の構成について詳しく説明する。
　なお、第二ホッパ１４３・１４３の内部にそれぞれ具備される選別網２４０・２４０は、選別網２３０・２３０と略同一構成であるので、その説明は省略する。 Hereinafter, the configuration of the sorting networks 230 and 230 provided in the first hoppers 133 and 133 will be described in detail with reference to FIG.
In addition, since the selection networks 240 and 240 respectively provided in the second hoppers 143 and 143 have substantially the same configuration as the selection networks 230 and 230, description thereof is omitted.
　選別網２３０・２３０は、第一ホッパ１３３・１３３に収容される肥料のうち所定の大きさの肥料のみを第一繰り出し部１３６・１３６へと通過させる網目状の部材である。選別網２３０・２３０は、第一ホッパ１３３・１３３内の上下中途部で水平方向に配置されて、湿気を吸収して固まった肥料塊が第一繰り出し部１３６・１３６に流下するのを阻止するとともに、ブリッジ現象によって肥料の流下が妨げられるのを阻止することもできる。 The sorting nets 230 and 230 are mesh-like members that allow only fertilizers of a predetermined size among the fertilizers accommodated in the first hoppers 133 and 133 to pass to the first feeding parts 136 and 136. The sorting nets 230 and 230 are disposed horizontally in the upper and lower middle portions of the first hoppers 133 and 133 to prevent the solidified fertilizer lump that has absorbed moisture from flowing down to the first feeding portions 136 and 136. At the same time, it is possible to prevent the flow of fertilizer from being hindered by the bridging phenomenon.
　選別網２３０・２３０は、選別網回動支持軸２３１・２３１をそれぞれ具備する。
　選別網回動支持軸２３１・２３１は、第一ホッパ１３３・１３３内部において第一回動機構１６０の第一回動支持軸１６２と平行に前後方向に配置されて第一ホッパ１３３・１３３に支持される。選別網回動支持軸２３１・２３１は第一回動支持軸１６２に対して左右反対側の選別網２３０・２３０の端部に設けられる。本実施の形態においては、選別網２３０・２３０のそれぞれ左側辺が選別網回動支持軸２３１・２３１を介して第一ホッパ１３３・１３３内部に上方回動可能に枢支するものである。但し、メンテナンス等を考慮して選別網２３０・２３０は第一ホッパ１３３・１３３に対して着脱可能に構成されている。また、選別網２３０・２３０の選別網回動支持軸２３１・２３１とそれぞれ反対側（選別網２３０・２３０のそれぞれ右側）は、第一ホッパ１３３・１３３内面に当接しているが、載置部等を設けて載置する構成であってもよい。こうして、通常時（第一上部施肥機１３０が上方へ回動していない時）には、選別網２３０・２３０は略水平に配置されるように構成される。 The sorting nets 230 and 230 include sorting net turning support shafts 231 and 231, respectively.
The sorting net rotation support shafts 231 and 231 are arranged in the front-rear direction in parallel with the first rotation support shaft 162 of the first rotation mechanism 160 inside the first hopper 133 and 133 and supported by the first hopper 133 and 133. Is done. The sorting screen rotation support shafts 231 and 231 are provided at the ends of the sorting screens 230 and 230 on the opposite side to the first rotation support shaft 162. In the present embodiment, the left side of each of the sorting nets 230 and 230 is pivotally supported inside the first hopper 133 and 133 via the sorting net turning support shafts 231 and 231. However, in consideration of maintenance and the like, the sorting nets 230 and 230 are configured to be detachable from the first hoppers 133 and 133. The opposite sides of the sorting nets 230 and 230 to the sorting net rotation support shafts 231 and 231 (the right sides of the sorting nets 230 and 230, respectively) are in contact with the inner surfaces of the first hoppers 133 and 133. Etc. may be provided and placed. Thus, during normal times (when the first upper fertilizer machine 130 is not rotating upward), the sorting nets 230 and 230 are configured to be arranged substantially horizontally.
　内部に残った肥料を排出するために、第一上部施肥機１３０を上方へ回動した際には、選別網２３０・２３０は、自重により選別網回動支持軸２３１・２３１から下側鉛直方向に懸吊される。その結果、選別網２３０・２３０（のそれぞれ右側端部）と第一ホッパ１３３・１３３（のそれぞれ内側）とが離間し隙間が形成される。そして選別網２３０・２３０の下方に残存する肥料は、第一ホッパ１３３・１３３の内側の傾斜に従い、第一上部施肥機１３０の上方への回動により肥料が残存する選別網２３０・２３０の下方よりも下側に位置することになった前記隙間から排出される。 When the first upper fertilizer machine 130 is rotated upward in order to discharge the fertilizer remaining inside, the sorting nets 230 and 230 are lowered from the sorting net turning support shafts 231 and 231 by their own weight in the lower vertical direction. Suspended by. As a result, the sorting screens 230 and 230 (respectively right end portions) and the first hoppers 133 and 133 (respectively inner sides) are separated to form a gap. The fertilizer remaining below the sorting nets 230 and 230 follows the inclination of the inside of the first hoppers 133 and 133 and below the sorting nets 230 and 230 where the fertilizer remains by the upward rotation of the first upper fertilizer applicator 130. It is discharged from the gap that is located on the lower side.
　前述のとおり第一ホッパ１３３・１３３が互いに対向する側の側面には、それぞれ切り欠き部１３３ａ・１３３ａが形成され、互いの内部空間が連通される。従って、第一上部施肥機１３０が上方へ回動した姿勢において上側の第一ホッパ１３３から排出される肥料は、切り欠き部１３３ａ・１３３ａを介して下側の第一ホッパ１３３の内部へと落下する。そして落下した肥料は、その下側の第一ホッパ１３３の肥料とともに連通孔１３３ｂから下側の第一ホッパ１３３の外部へと排出される。 As described above, the notches 133a and 133a are formed on the side surfaces of the first hoppers 133 and 133 that face each other, and the internal spaces are communicated with each other. Accordingly, the fertilizer discharged from the upper first hopper 133 in the posture in which the first upper fertilizer machine is rotated upward falls to the inside of the lower first hopper 133 through the notches 133a and 133a. To do. Then, the dropped fertilizer is discharged from the communication hole 133b to the outside of the lower first hopper 133 together with the fertilizer of the lower first hopper 133.
　以上のように構成することにより、第一上部施肥機１３０を上方へ回動した際、選別網２３０・２３０は自由に回動し、選別網２３０・２３０（のそれぞれ右側端部）と第一ホッパ１３３・１３３（のそれぞれ内側）とが離間し隙間が形成されるので、第一ホッパ１３３・１３３内の肥料、特に選別網２３０・２３０の下方に残存する肥料をスムースに排出することができる。よって、施肥装置１００内の肥料の排出及び清掃の効率化を図ることができる。また、選別網２３０・２３０は、選別網回動支持軸２３１・２３１により枢支されているため、第一上部施肥機１３０の回動時に選別網２３０・２３０が外れたり、取り付け位置がずれたりすることがない。 With the above-described configuration, when the first upper fertilizer applicator 130 is rotated upward, the sorting nets 230 and 230 are freely rotated, and the sorting nets 230 and 230 (each of the right end portions thereof) and the first Since the hoppers 133 and 133 are separated from each other and a gap is formed, the fertilizer in the first hoppers 133 and 133, particularly the fertilizer remaining below the sorting nets 230 and 230, can be smoothly discharged. . Therefore, discharge | emission of the fertilizer in the fertilizer application apparatus 100 and efficiency improvement of cleaning can be achieved. Further, since the sorting nets 230 and 230 are pivotally supported by the sorting net rotation support shafts 231 and 231, the sorting nets 230 and 230 are detached or the mounting positions are shifted when the first upper fertilizer is rotated. There is nothing to do.
　また、選別網２３０・２３０を前述と異なる構成とすることができる。
　即ち、図２０に示すように、選別網２３０・２３０は少なくとも二以上に分割され、選別網回動支持軸２３１・２３１はその分割された選別網２３０・２３０のうち第一回動支持軸１６２に最も近い側の選別網２３０・２３０を回動可能に枢支する構成とすることができる。以下、詳しく説明する。 Further, the sorting networks 230 and 230 can be configured differently from the above.
That is, as shown in FIG. 20, the sorting screens 230 and 230 are divided into at least two, and the sorting screen rotation support shafts 231 and 231 are the first rotation support shaft 162 of the divided sorting screens 230 and 230. It is possible to adopt a configuration in which the sorting nets 230 and 230 on the side closest to are pivotally supported. This will be described in detail below.
　本実施の形態においては、選別網２３０・２３０はそれぞれ略同一の大きさにて二分割されている。ここで、第一ホッパ１３３・１３３の通常時（第一上部施肥機１３０が上方へ回動していない時）において、分割された選別網２３０・２３０のそれぞれ左側を選別網２３０ａ・２３０ａと、それぞれ右側を選別網２３０ｂ・２３０ｂとする。
　なお、選別網２３０・２３０は二分割に限定するものではなく本発明の目的を達成できるならば三分割等であってもよい。 In the present embodiment, the sorting networks 230 and 230 are each divided into two parts having substantially the same size. Here, in the normal time of the first hoppers 133 and 133 (when the first upper fertilizer machine 130 is not rotating upward), the left sides of the divided sorting nets 230 and 230 are the sorting nets 230a and 230a, The right side is designated as a sorting network 230b / 230b.
The selection networks 230 and 230 are not limited to two divisions, and may be three divisions or the like as long as the object of the present invention can be achieved.
　第一回動支持軸１６２に対して遠い側の選別網２３０ａ・２３０ａは、それぞれ第一ホッパ１３３・１３３の内側に通常時において選別網２３０ａ・２３０ａが略水平となるように固着される。そして、選別網２３０ｂ・２３０ｂの左側端部（第一回動支持軸１６２と反対側の辺）には選別網回動支持軸２３１・２３１が具備される。 The sorting screens 230a and 230a on the side far from the first rotation support shaft 162 are fixed inside the first hoppers 133 and 133, respectively, so that the sorting screens 230a and 230a are substantially horizontal during normal times. In addition, sorting screen rotation support shafts 231 and 231 are provided on the left ends of the selection screens 230b and 230b (sides opposite to the first rotation support shaft 162).
　選別網２３０ｂ・２３０ｂは、左側端部が選別網回動支持軸２３１・２３１により上方回動可能に枢支される。選別網２３０ｂ・２３０ｂの右側端部は、第一ホッパ１３３・１３３内に当接され、通常時において選別網２３０ｂ・２３０ｂは、略水平に配置される。
　従って、通常時において選別網２３０ａ・２３０ａと選別網２３０ｂ・２３０ｂとは、互いに略水平となるように第一ホッパ１３３・１３３内に構成される。 The sorting nets 230b and 230b are pivotally supported at their left end portions by the sorting net turning support shafts 231 and 231 so as to be rotatable upward. The right end portions of the sorting nets 230b and 230b are brought into contact with the first hoppers 133 and 133, and the sorting nets 230b and 230b are arranged substantially horizontally in a normal state.
Therefore, in a normal time, the sorting nets 230a and 230a and the sorting nets 230b and 230b are configured in the first hoppers 133 and 133 so as to be substantially horizontal to each other.
　内部に残った肥料を排出するために、第一上部施肥機１３０を上方へ回動すると、選別網２３０ｂ・２３０ｂは、自重により選別網回動支持軸２３１・２３１を中心回動して下側鉛直方向に懸吊される。その結果、選別網２３０ｂ・２３０ｂ（の右側端部）と第一ホッパ１３３・１３３（のそれぞれ内側）とが離間し隙間が形成される。そして選別網２３０・２３０の下方に残存する肥料は、第一ホッパ１３３・１３３の内側の傾斜に従い、第一上部施肥機１３０の上方への回動により肥料が残存する選別網２３０・２３０の下方よりも下方に位置することになった前記隙間から排出される。 When the first upper fertilizer is rotated upward to discharge the fertilizer remaining in the interior, the sorting nets 230b and 230b rotate about the sorting net turning support shafts 231 and 231 by their own weights, and the lower side Suspended vertically. As a result, the sorting nets 230b and 230b (the right end portion thereof) and the first hoppers 133 and 133 (the inner sides thereof) are separated to form a gap. The fertilizer remaining below the sorting nets 230 and 230 follows the inclination of the inside of the first hoppers 133 and 133 and below the sorting nets 230 and 230 where the fertilizer remains by the upward rotation of the first upper fertilizer applicator 130. It is discharged from the gap that has been positioned below.
　以上のように構成することにより、第一上部施肥機１３０を上方へ回動した際、選別網２３０ｂ・２３０ｂは自由に回動し、選別網２３０ｂ・２３０ｂと第一ホッパ１３３・１３３とが離間し隙間が形成されるので、第一ホッパ１３３・１３３内の肥料、特に選別網２３０・２３０の下方に残存する肥料をスムースに排出することができる。また、第一ホッパ１３３・１３３内の肥料を排出するために回動させることが必要な選別網２３０ｂ・２３０ｂのみを回動可能に構成することにより、選別網の回動が肥料の排出を阻害することを防止することができる。よって、施肥装置１００内の肥料の排出及び清掃の効率化を図ることができる。
　そしてさらに、第一上部施肥機１３０を上方へ回動した際に上側となる第一ホッパ１３３から肥料が、切り欠き部１３３ａを介して落下すると、図１９に示す第一実施例では、肥料は下側の選別網２３０に当たる可能性があるが、左右分割することにより、選別網２３０ｂの下端の回動量は小さくなり、上から落下する肥料が下側の選別網２３０ｂに当接することが少なくなり、粉砕等を防止することが可能となる。 With the above configuration, when the first upper fertilizer machine 130 is rotated upward, the sorting nets 230b and 230b are freely rotated, and the sorting nets 230b and 230b are separated from the first hoppers 133 and 133. Since the gap is formed, the fertilizer in the first hoppers 133 and 133, particularly the fertilizer remaining below the sorting nets 230 and 230, can be discharged smoothly. Moreover, only the sorting nets 230b and 230b that need to be rotated to discharge the fertilizer in the first hoppers 133 and 133 are configured to be rotatable so that the rotation of the sorting nets inhibits the discharge of the fertilizer. Can be prevented. Therefore, discharge | emission of the fertilizer in the fertilizer application apparatus 100 and efficiency improvement of cleaning can be achieved.
Further, when the fertilizer falls from the first hopper 133 which is the upper side when the first upper fertilizer applicator 130 is rotated upward, in the first embodiment shown in FIG. Although there is a possibility of hitting the lower sorting net 230, the amount of rotation of the lower end of the sorting net 230b is reduced by dividing the left and right, and the fertilizer falling from above is less likely to come into contact with the lower sorting net 230b. It is possible to prevent crushing and the like.
　また、選別網２３０は分割せずに、上方へ回動した際に上側となる第一ホッパ１３３から落下する肥料が下側の第一ホッパ１３３内の選別網２３０に当たらないように、下側の第一ホッパ１３３内の選別網２３０の回動を規制する構成とすることもできる。
　即ち、図２１に示すように、上方へ回動した際に下側となる外側の第一ホッパ１３３内の選別網２３０の回動軌跡途中に所定の角度において下方への回動を規制する規制部材２３３を第一ホッパ１３３に具備する構成としている。以下、詳しく説明する。 In addition, the sorting net 230 is not divided, so that the fertilizer falling from the upper first hopper 133 when rotating upward does not hit the sorting net 230 in the lower first hopper 133. It can also be set as the structure which controls rotation of the selection net | network 230 in the 1st hopper 133 of this.
That is, as shown in FIG. 21, a restriction that restricts the downward rotation at a predetermined angle in the middle of the rotational trajectory of the sorting net 230 in the outer first hopper 133 that is the lower side when it is rotated upward. The member 233 is provided in the first hopper 133. This will be described in detail below.
　上方へ回動した際に下側となる外側の第一ホッパ１３３内において、選別網２３０が前記同様に第一ホッパ１３３内の上下中途部に水平に配置され、選別網回動支持軸２３１が第一回動支持軸１６２に対して左右反対側の選別網２３０の端部に設けられる。そして、前記規制部材２３３は、ピン等の突起部材で構成され、第一ホッパ１３３の前面または後面から内部方向に突設されている。規制部材２３３の配置位置は、選別網２３０の回動軌跡途中であって、第一ホッパ１３３を上方へ回動した状態において、選別網２３０が鉛直方向を向いた角度よりも小さな角度となる位置である。但し、規制部材２３３の配置位置は前記位置に限定するものではなく、選別網回動支持軸２３１を選別網２３０に固設して、該選別網回動支持軸２３１近傍に規制部材２３３を配置して回動角度を規制する構造とすることもできる。 In the first outer hopper 133 that is the lower side when rotated upward, the sorting screen 230 is horizontally disposed in the middle of the upper and lower sides in the first hopper 133 as described above, and the sorting screen rotation support shaft 231 is arranged. It is provided at the end portion of the sorting screen 230 on the opposite side to the first rotation support shaft 162. The restricting member 233 is formed of a protruding member such as a pin, and protrudes inward from the front or rear surface of the first hopper 133. The arrangement position of the regulating member 233 is in the middle of the turning trajectory of the sorting net 230, and in a state where the first hopper 133 is pivoted upward, the sorting net 230 is at a position smaller than the angle in which the sorting net 230 faces the vertical direction. It is. However, the arrangement position of the regulating member 233 is not limited to the above position, and the sorting net rotation support shaft 231 is fixed to the sorting net 230 and the regulation member 233 is arranged in the vicinity of the sorting net rotation support shaft 231. Thus, a structure that restricts the rotation angle can also be adopted.
　こうして、前述のとおり選別網２３０の回動角度を所定の角度に規制することができるようにしている。すなわち、第一上部施肥機１３０を上方へ回動した際には、選別網２３０・２３０は、自重力により選別網回動支持軸２３１・２３１を中心に下側鉛直方向に懸吊されようとするが、下側の選別網２３０は規制部材２３３により回動が中途で規制される。即ち、規制部材２３３を備えることにより、選別網２３０の右側端部と第一ホッパ１３３内面との隙間の距離を予め設定することができる。 Thus, as described above, the rotation angle of the sorting screen 230 can be restricted to a predetermined angle. That is, when the first upper fertilizer machine 130 is rotated upward, the sorting nets 230 and 230 are suspended by the gravity in the lower vertical direction around the sorting net turning support shafts 231 and 231. However, rotation of the lower sorting net 230 is regulated by the regulating member 233 midway. That is, by providing the restriction member 233, the distance between the right end of the sorting screen 230 and the inner surface of the first hopper 133 can be set in advance.
　以上のように構成することにより、第一上部施肥機１３０を上方へ回動した際、選別網２３０と第一ホッパ１３３との隙間の距離を予め設定することができるので、選別網２３０が必要以上に回動することがなく、上側のホッパ内から落下する肥料の排出を阻害することを防止できる。よって、施肥装置１００内の肥料の排出及び清掃の効率化を図ることができる。 By configuring as described above, the distance between the sorting net 230 and the first hopper 133 can be set in advance when the first upper fertilizer machine 130 is rotated upward, so the sorting net 230 is necessary. It does not rotate as described above, and it can be prevented that the discharge of the fertilizer falling from the upper hopper is inhibited. Therefore, discharge | emission of the fertilizer in the fertilizer application apparatus 100 and efficiency improvement of cleaning can be achieved.
　本発明は、乗用田植機等の作業機械に具備され、圃場に施肥する施肥装置の技術に利用することが可能であり、特に施肥装置内の肥料の排出及び清掃の効率化を図るための技術に利用することが可能である。 INDUSTRIAL APPLICABILITY The present invention is provided in a work machine such as a riding rice transplanter, and can be used for a technique of a fertilizer applying fertilizer to a farm field, and in particular, a technique for improving the efficiency of discharging and cleaning fertilizer in the fertilizer applying apparatus. It is possible to use it.
