Description

本発明は、肥料を散布する肥料散布機のホッパの支持構造に関し、詳しくは、ホッパを肥料の散布状態と残留肥料の除去作業状態とに交互に切り替えられるようにしたホッパの支持構造に関する。   The present invention relates to a support structure for a hopper of a fertilizer spreader that sprays fertilizer, and more particularly to a support structure for a hopper that can be switched alternately between a fertilizer application state and a residual fertilizer removal operation state.

肥料散布機に備えられているホッパは、新たに収容する肥料の落下抵抗を低減して効率的に落下させるようにしたり、新たに収容する肥料や種類の異なる肥料に対して悪影響を与えたりしないようにするため、ホッパ内に付着等により残留する肥料を定期的に除去している。
ホッパ内の残留肥料を除去する作業は、ホッパを肥料散布機に取り付けた状態で行うこともあるし、より確実に残留肥料を除去する必要性があるものや、ホッパの落下口が連結される散布装置の連結口に残留する肥料を除去する必要があるものについては、肥料散布機からホッパを取外して行うこともある。
The hopper provided in the fertilizer spreader reduces the fall resistance of newly stored fertilizer so that it can be dropped efficiently, and does not adversely affect newly stored fertilizer or different types of fertilizer Therefore, the fertilizer remaining in the hopper due to adhesion or the like is periodically removed.
The work to remove the residual fertilizer in the hopper may be performed with the hopper attached to the fertilizer spreader, or there is a need to remove the residual fertilizer more reliably, or the hopper's drop opening is connected For those that need to remove the fertilizer remaining at the connection port of the spreader, the hopper may be removed from the fertilizer spreader.

ところで、ホッパ内での落下時に作用する滑り抵抗が大きく滑り難い肥料を散布する際に、ホッパ内での詰まりによる散布不良が発生しやすいため、残留肥料の除去作業をより確実に、しかも頻繁に行うことが必要であるので、残留肥料の除去作業は、ホッパを取外して行うことが好ましい。
しかしながら、広範囲に亘って移動しながら肥料を散布する肥料散布機に備えられるホッパでは、肥料の散布を効率的に行うようにすることから、ある程度収容量が確保された比較的大型のホッパが使用されており、しかも、ホッパの落下口が連結される散布装置には、ホッパ内の肥料の詰り防止する攪拌スクリュ等が装備されているため、該攪拌スクリュ等に破損させるような衝撃を与えないようにホッパを着脱することが困難なものであって、現実的には、残留肥料の除去を確実に行うための前記好ましい方法が行い難いものであった。
By the way, when spraying fertilizer that has a large slip resistance and is difficult to slip when it falls in the hopper, spraying failure due to clogging in the hopper is likely to occur, so the removal of residual fertilizer more reliably and frequently Since it is necessary to perform, it is preferable to perform the removal operation of the residual fertilizer by removing the hopper.
However, in the hopper provided in the fertilizer spreader that spreads the fertilizer while moving over a wide range, a relatively large hopper with a certain amount of storage capacity is used to efficiently spread the fertilizer. In addition, since the spraying device to which the hopper dropping port is connected is equipped with a stirring screw or the like for preventing clogging of the fertilizer in the hopper, the stirring screw or the like is not damaged. Thus, it is difficult to attach and detach the hopper, and practically, it is difficult to perform the preferred method for reliably removing the residual fertilizer.

次に例示する肥料散布機は、ホッパを肥料散布機から取外すことなく、残留肥料の除去を行うためのホッパの支持構造を備えたものである。(非特許文献1参照)
http://www.takakita-net.co.jp/dl/documents/bcl.pdf
The fertilizer spreader illustrated next includes a hopper support structure for removing residual fertilizer without removing the hopper from the fertilizer spreader. (See Non-Patent Document 1)
http://www.takakita-net.co.jp/dl/documents/bcl.pdf

例示した非特許文献1に記載の肥料散布機は、肥料散布機を構成する各部材を支持するフレーム本体と、ホッパを固定支持したホッパ用フレームとからなるフレームでホッパを支持し、前記ホッパ用フレームをフレーム本体に対して、ホッパの軸線が該ホッパの径方向に沿って倒れる方向に回動するように定点で軸支した構造である。   The illustrated fertilizer spreader described in Non-Patent Document 1 supports a hopper with a frame composed of a frame body that supports each member constituting the fertilizer spreader and a hopper frame that fixes and supports the hopper. In this structure, the frame is pivotally supported at a fixed point with respect to the frame main body so as to rotate in a direction in which the axis of the hopper falls down along the radial direction of the hopper.

このホッパの支持構造によれば、肥料の散布状態では、ホッパの軸線がほぼ鉛直線に沿っており、ホッパの投入口が上向きで、ホッパの落下口が下向きの状態で該落下口が散布装置の連結口に対して着脱可能に連結されている立設状態にある。
前記散布状態から残留肥料の除去作業状態に切り替える動作は、ホッパ用フレームを作業者自身が軸支部を回動中心として前記した方向に回動して前記ホッパを倒す。
すると、ホッパの投入口が斜め横向きとなるように倒れた状態となるため、ホッパ内の残留肥料を、例えば、ほうきやブラシ等で掃き出したり、スクレーパ等で掻き出したり、更には拭き取ったりすることができ、ホッパの落下口も前記投入口と同様に斜め横向きとなって連結口から離間することで、連結口との連結が解除されて連結口内が露出するため、連結口内の残留肥料もほうきやブラシ等で掃き出すことが容易にできる除去状態となる。
そして、この除去状態から前記散布状態に戻す際には、ホッパ用フレームを作業者自身が軸支部を回動中心として前記した方向と逆方向に回動して、ホッパを立設状態にすればよい。
According to this hopper support structure, in the fertilizer application state, the axis of the hopper is substantially along the vertical line, the hopper inlet is upward, the hopper drop is downward, and the drop is spreader It is in the standing state connected so that attachment or detachment is possible.
In the operation of switching from the sprayed state to the residual fertilizer removing work state, the operator turns the hopper frame in the above-described direction with the shaft support portion as the turning center, and defeats the hopper.
Then, since the inlet of the hopper is tilted so as to be inclined sideways, the residual fertilizer in the hopper may be swept out with, for example, a broom or a brush, scraped out with a scraper, or even wiped off. The hopper dropping port is also inclined sideways like the charging port and separated from the connecting port, so that the connection with the connecting port is released and the inside of the connecting port is exposed. The removed state can be easily swept out with a brush or the like.
Then, when returning from the removed state to the spraying state, if the operator turns the hopper frame in the direction opposite to the above-mentioned direction with the shaft support portion as the rotation center, the hopper is in the standing state. Good.

すなわち、ホッパを取外さなくてもホッパ内及び連結口内の残留肥料を除去することができ、しかも、ホッパ用フレームが定点で回動可能に軸支されていることから、このホッパ用フレームの回動に伴って回動するホッパが常に同じ軌道上を回動するため、落下口と連結口との連結及び連結解除時において、攪拌スクリュ等に対して落下口付近が接触することを防止することができる。   That is, residual fertilizer in the hopper and the connection port can be removed without removing the hopper, and the hopper frame is pivotally supported at a fixed point. Since the hopper that rotates with the movement always rotates on the same track, it is possible to prevent the vicinity of the dropping port from coming into contact with the stirring screw or the like when the dropping port is connected to or disconnected from the connecting port. Can do.

ところで、前記ホッパ用フレームのホッパの支持構造は、ホッパの傾斜面部が貫通状に嵌合する支持リングと、該支持リングの内周縁に固定され、ホッパの傾斜面部分に対して正対状に固定してホッパを支持する複数の支持板と、支持リングの下縁から垂設され、下端部がフレームに対して回動可能に軸支された2枚の軸支板とから構成されているため、ホッパ用フレーム及びホッパの重量が相当大きなものとなっている。
すなわち、前記肥料散布機では、前記ホッパ用フレーム及びホッパの重量が作業者による切替え動作に対して作用するため、その重量を支えながらホッパ用フレームを回動することが困難なものであった。
By the way, the hopper support structure of the hopper frame has a support ring in which the inclined surface portion of the hopper is fitted in a penetrating manner, and is fixed to the inner peripheral edge of the support ring so as to face the inclined surface portion of the hopper. It is composed of a plurality of support plates that are fixed and support the hopper, and two shaft support plates that are suspended from the lower edge of the support ring and whose lower ends are pivotally supported with respect to the frame. Therefore, the weight of the hopper frame and the hopper is considerably large.
That is, in the fertilizer spreader, since the weight of the hopper frame and the hopper acts on the switching operation by the operator, it is difficult to rotate the hopper frame while supporting the weight.

本形態のホッパの支持構造は、ホッパ2の散布状態(図1,図2参照)では、前記被支持部6が散布状態側支持部7Aに係合すると共に、第1保持部8A、及び第2保持部8Bにより立設状態が保持されている。
前記散布状態において、第1保持部8A、及び第2保持部8Bによる保持を解除することにより、ホッパ2を倒した状態に切替え可能な状態にすることができ、該切替え可能状態から、ホッパ2を後側に倒そうとすると、ホッパ2が前記支点部9を支点とする梃子の作用により倒れる(図1参照)。
このホッパ2が倒れる動作では、被支持部6が前記案内部7Cの円弧に沿って案内されながら前記除去状態側支持部7Bに向かって移動し、該除去状態側支持部7Bに係合することにより、ホッパ2が完全に倒れた状態となると共に、前記落下口3が前記連結口41から外れて該連結口41が露出した状態となる(図1,図3参照)。
そして、ホッパ2が完全に倒れた状態で、前記第1保持部8Aで被支持部6の除去状態側支持部7Bに対する係合状態を保持することによって、ホッパ2を除去状態にすることができる(図3参照)。

From the switchable state, the hopper 2 When the hopper 2 is tilted to the rear side, the hopper 2 is tilted by the action of the lever having the fulcrum portion 9 as a fulcrum (see FIG. 1).
In the operation of the hopper 2 tilting, the supported portion 6 moves toward the removal state side support portion 7B while being guided along the arc of the guide portion 7C, and engages with the removal state side support portion 7B. As a result, the hopper 2 is completely collapsed, and the drop port 3 is detached from the connection port 41 so that the connection port 41 is exposed (see FIGS. 1 and 3).
Then, the hopper 2 can be brought into the removed state by holding the engaged state of the supported portion 6 with respect to the removed state side support portion 7B with the first holding portion 8A in a state where the hopper 2 is completely collapsed. (See FIG. 3).

前記ホッパ2を除去状態から散布状態に戻す場合には、第1保持部8Aによる保持を解除し、ホッパ2を前側方向へ立たせようとすると、被支持部6が案内部7Cに沿って散布状態側支持部7Aに向かって移動し、該散布状態側支持部7Aに係合することにより、前記落下口3が連結口41に嵌合した立設状態となる(図1,図2参照)。
そして、第1保持部8A、及び第2保持部8Bにより立設状態を保持することにより、ホッパ2を散布状態にすることができる(図1,図2参照)。
When returning the hopper 2 from the removed state to the spraying state, if the holding by the first holding portion 8A is released and the hopper 2 is to be raised in the front direction, the supported portion 6 is in the spraying state along the guide portion 7C. By moving toward the side support portion 7A and engaging with the spraying state side support portion 7A, the dropping port 3 is brought into a standing state in which the connection port 41 is fitted (see FIGS. 1 and 2).
And the hopper 2 can be made into a dispersion | spreading state by hold | maintaining a standing state by 8 A of 1st holding parts and the 2nd holding part 8B (refer FIG. 1, FIG. 2).

したがって、本形態のホッパの支持構造によれば、ホッパ2のみを前後方向に倒したり立たせたりするという容易な動作により、立設状態と倒した状態に切替えることができる。
しかも、ホッパ2を倒す動作では、支点部9による梃子の作用を利用し、且つ被支持部6が案内部7Cにより案内されるので、ホッパ2を倒す動作をより容易に行うことができる。
更に、第1保持部8A、及び第2保持部8Bでホッパ2の散布状態を確実に保持し、第1保持部8Aでホッパ2の除去状態を確実に保持することができる。
ホッパの立設状態と倒れた状態との切替え作業の容易性向上が実現した肥料散布機のホッパの支持構造を提供することができる。
又、第1保持部8A、及び第2保持部8Bの保持を解除すれば、ホッパ2を取外すこともできるので、ホッパ2の交換等も簡単に行うことができる。

A detailed description of the form is omitted.
Further, the configuration and holding form of the lock handle 8E are the same as and the same holding form as the lock handle 81 exemplified in the first form. By attaching the same reference numerals as those of the constituent members of the lock handle 81, the detailed description thereof will be omitted.

前記挟持凹部8Fは、除去状態側支持部7B'の端部から垂設された支持板70のホッパ2側の面に、開放端側をホッパ2側に向けて突設され、前記ホッパ2が倒れた状態にされた際に、前記案内突起62を左右方向から挟み込んで保持するようにされている。
又、挟持凹部8Fは、案内突起62を左右方向から挟み込む方向に付勢力が作用するばね機能を有するものである。
The clamping recess 8F is provided on the hopper 2 side surface of the support plate 70 suspended from the end of the removed state side support portion 7B ′ so that the open end side faces the hopper 2 side. The guide protrusion 62 is sandwiched and held from the left and right directions when it is in a fallen state.
The sandwiching recess 8F has a spring function in which an urging force acts in a direction in which the guide projection 62 is sandwiched from the left and right directions.

The hopper support structure exemplified in this embodiment is such that the switching operation between the standing state and the collapsed state of the hopper 2 is made in the left-right direction.
Moreover, since the form of the supported part 6 and the form of the support part 7 of this embodiment are the same as those exemplified in the second embodiment, detailed description thereof will be omitted by attaching the same reference numerals.

本形態の保持手段8は、前記第1形態で例示した第2保持部8Bと同形態の嵌合保持部8Gからなる第1保持部8A''と、前記被支持部6と散布状態側支持部7A'、及び被支持部6と除去状態側支持部を締め付け固定する蝶螺子8Hからなる第2保持部8B''と、前記被支持部6と対称位置のホッパ2の傾斜面部21に対して固着された支持体8I・該支持体8I支持する支持板8J・該支持板8Jに対して前記支持体8Iを締め付け固定する蝶螺子8Kからなる第3保持部80とから構成されている。   The holding means 8 of the present embodiment includes a first holding portion 8A ″ comprising a fitting holding portion 8G having the same form as the second holding portion 8B exemplified in the first embodiment, the supported portion 6 and the dispersed state side support. Part 7A ′, a second holding part 8B ″ comprising a butterfly screw 8H for fastening and fixing the supported part 6 and the removed state side support part, and the inclined surface part 21 of the hopper 2 at a position symmetrical to the supported part 6 The support body 8I fixed to the support body 8A, the support plate 8J supporting the support body 8I, and the third holding portion 80 including the butterfly screw 8K for fastening and fixing the support body 8I to the support plate 8J.

前記嵌合保持部8Gは、前記第1形態で例示した第2保持部8Bと同形態であるので、同符号を付すことにより、その具体的な説明は省略する。
前記蝶螺子8Hは、支持部7の外側から前記案内孔71を介して被支持部6に螺合しており、該蝶螺子8Hを締め付けることにより、該蝶螺子8Hと被支持部6とで支持部7を挟持して、ホッパ2の散布状態と除去状態とを保持するようにし、蝶螺子8Hの締め付けを緩めることにより、ホッパ2の散布状態と除去状態との保持を解除して、ホッパ2の立設状態と除去状態との切替えを行うことができる。
又、ホッパ2の立設状態と除去状態との切替え動作では、前記蝶螺子8Hが第2形態における案内突起62と同様に、案内孔71に貫通した状態で案内される。
前記支持体8Iは、前記被支持部6と略対称形状としたものであり、前記支持板8Jは、前記支持部7における案内部7C'と除去状態側支持部7B'を取り除き、散布状態側支持部7A'を残したような形態の板状のものである。
又、前記支持板8Jには、前記蝶螺子8Kがホッパ2の立設状態で係合し、倒れた状態で係合が解除される凹部81Iが形成されており、ホッパ2の立設状態と倒れた状態との切替え動作時において、前記蝶螺子8Kが上下方向に係脱するように形成されている。
又、前記蝶螺子8Kは、前記蝶螺子8Hと同様に、支持体8Iに対して支持板8Jの外側から前記凹部81Iを介して支持体8Iに螺合しており、該蝶螺子8Kを締め付けることにより、該蝶螺子8Kと支持体8Iとで支持板8Jを挟持して、ホッパ2の散布状態を保持し、蝶螺子8Kの締め付けを緩めることにより、ホッパ2の散布状態の保持を解除するようにしている。
Since the fitting holding part 8G has the same form as the second holding part 8B exemplified in the first form, a detailed description thereof will be omitted by attaching the same reference numerals.
The butterfly screw 8H is screwed into the supported portion 6 from the outside of the support portion 7 through the guide hole 71. By tightening the butterfly screw 8H, the butterfly screw 8H and the supported portion 6 are connected. By holding the support portion 7 so as to hold the spraying state and the removal state of the hopper 2 and loosening the tightening of the butterfly screw 8H, the holding of the hopper 2 between the spraying state and the removal state is released, and the hopper 2 can be switched between the standing state and the removal state.
Further, in the switching operation between the standing state and the removal state of the hopper 2, the butterfly screw 8H is guided in a state of penetrating the guide hole 71 in the same manner as the guide protrusion 62 in the second embodiment.
The support body 8I has a substantially symmetrical shape with the supported portion 6, and the support plate 8J removes the guide portion 7C ′ and the removed state side support portion 7B ′ in the support portion 7 to thereby disperse the dispersion state side. It is a plate-like shape in which the support portion 7A ′ is left.
Further, the support plate 8J is formed with a recess 81I in which the butterfly screw 8K is engaged when the hopper 2 is erected and is released when the hopper 2 is tilted. The hinge screw 8K is formed so as to be engaged and disengaged in the vertical direction during the switching operation to the fallen state.
Similarly to the butterfly screw 8H, the butterfly screw 8K is screwed to the support body 8I from the outside of the support plate 8J to the support body 8I through the recess 81I, and tightens the butterfly screw 8K. As a result, the support plate 8J is sandwiched between the butterfly screw 8K and the support body 8I to maintain the sprayed state of the hopper 2 and loosen the tightening of the butterfly screw 8K to release the hold of the hopper 2 from the sprayed state. I am doing so.

本形態のホッパの支持構造は、ホッパ2の散布状態では、前記被支持面61が散布状態側支持部7A'と正対すると共に、第1保持部8A''・第2保持部8B''・第3保持部80により立設状態が保持されている。
前記散布状態において、第1保持部8A''・第2保持部8B''・第3保持部80による保持を解除することにより、ホッパ2を倒した状態に切替え可能な状態にすることができる。
そして、切替え可能状態から、ホッパ2を図面上左側に倒そうとすると、ホッパ2が前記支点部9Aを支点とする梃子の作用により倒れて、前記被支持面61が案内部7C'と正対し、更に後側に倒そうとすると、ホッパ2が前記支点部9Bを支点とする梃子の作用により倒れて、前記被支持面61が除去状態側支持部7B''と正対してホッパ2が倒れた状態となる。
そして、ホッパ2が倒れた状態を第2保持部8B''で保持することによって、倒れた状態が保持された除去状態となる。
この除去状態では、ホッパ2が完全に倒れた状態となると共に、前記落下口3が前記連結口41から外れて該連結口41が露出した状態となる。

In the spraying state, by releasing the holding by the first holding unit 8A ″, the second holding unit 8B ″, and the third holding unit 80, the hopper 2 can be switched to the tilted state. .
When the hopper 2 is to be tilted to the left in the drawing from the switchable state, the hopper 2 is tilted by the action of the lever with the fulcrum portion 9A as a fulcrum, and the supported surface 61 faces the guide portion 7C ′. If the hopper 2 is further tilted to the rear side, the hopper 2 is tilted by the action of the lever with the fulcrum portion 9B as a fulcrum, and the supported surface 61 faces the removed state side support portion 7B ″ and the hopper 2 falls. It becomes a state.
