Description

【０００１】
【発明の属する技術分野】
本発明は、自走又は牽引される堆肥散布車に関し、荷箱の後端下方に設けた散布装置上に堆肥を落下させ、堆肥を散布する堆肥散布装置に関するものである。
【０００２】
【従来の技術】
【特許文献１】特開平５−３０８０６号公報
荷箱の後下方に設けた左右一対の水平回転可能な散布装置の周辺部に交換自在な案内板を設け、この案内板によって堆肥の散布幅や散布方向、散布密度を変更可能にした技術が記載されている。
この案内板は散布羽根周囲に固定したものであり、散布方向を変更するためには各々の散布方向に応じた案内板の交換が必要なため散布作業途中に散布幅や散布方向を変更することがわずらわしいものであった。
【特許文献２】実公平７−５１８５０号公報
又、特許文献２には、荷箱の後下方に設けた左右一対の水平回転可能な散布装置の回転方向の選択切換えにより、堆肥の散布状態を、広幅散布、狭幅散布、右片側散布、左片側散布の各態様を選択できる技術が記載されている。
この技術は、堆肥を左側に放出させようとするときには、右側の側板に誘導部材を取付け、右側に堆肥を放出させようとするときには左側の側板に誘導部材を取付ける構成であり、特許文献１と同様に誘導部材を散布方向に応じて左右に付け替えなければならないものであった。
すなわち、特許文献１及び特許文献２に記載の技術は、一定量で荷箱の開口部から広範囲に飛散している堆肥を側方、又は中央で規制案内することにより散布幅や散布方向を変える技術であり、散布装置の真横方向への散布は行うことはできず、例えば果樹列間を走行しながら散布する場合、木の株元への散布が不十分なものとなっていた。
【０００３】
【発明が解決しようとする課題】
本発明は、堆肥の散布方向を容易に変えることができ、又、散布装置の真横方向への散布が可能な堆肥散布装置を提供することを課題とする。
【０００４】
【課題を解決するための手段】
荷箱１下方に設ける散布装置２上に堆肥３を落下させ、該散布装置２に軸支した水平回転可能な複数の散布翼４によって機体５の前方、又は後方への堆肥散布を行う堆肥散布車において、前記散布翼４下面に平行接近させた水平板７を設け、該水平板７に散布翼４の回転軌跡外周縁４ａに沿った形状の、一部開口部Ａを有する円弧状案内板８を立設するとともに、前記案内板８を該散布翼４の回転軸６中心に水平回動自在に構成し、該案内板８の開口部Ａの方向を少なくとも左右９０度の範囲変更可能にしてなる堆肥散布装置とする。
【０００５】
【発明の作用及び効果】
荷箱１下方に設ける散布装置２上に堆肥３を落下させ、該散布装置２に軸支した水平回転可能な複数の散布翼４によって、機体５の前方、又は後方への堆肥散布を行う堆肥散布車において、前記散布翼４下面に平行接近させた水平板７を設け、該水平板７に散布翼４の回転軌跡外周縁４ａに沿った形状の、一部開口部Ａを有する円弧状案内板８を立設してあるので、水平回転する散布翼４の下方に落下する堆肥は水平板７で受けることができるとともに、案内板８が散布翼４の回転軸６中心に水平回動自在であるので、簡単な構造で開口部Ａから散布する堆肥の散布方向を案内板８の交換をすることなく容易に変更することができる。又、案内板８の開口部Ａの方向を少なくとも左右９０度の範囲変更可能にしてあるので散布装置２の真横方向への散布が可能であり、果樹等の株元部に堆肥散布を行う場合には果樹列間での走行に応じて散布方向を容易に変更することができ、作業形態に応じた効率の良い散布が可能である。更に、散布した堆肥を走行装置が踏むことなく散布作業を行うことも可能である。
【０００６】
【発明の実施の形態】
次に、本発明の実施の形態を図面に基づいて説明する。図１に記載の堆肥散布車は、自走式の散布車を示し、前側フレーム１０に作業者が散布作業操作や走行操作を行うことのできる操作部１１と原動機１２とを搭載し、その後方には、底面をコンベアベルト１３で構成して後方への堆肥送り出しが可能の荷箱１を設けてある。荷箱１下方には、前記原動機１２からトランスミッション３０を介して駆動される左右一対の走行装置１４を設け、該走行装置１４は前方の駆動スプロケット１５と後方のテンション転輪１６及び複数の接地転輪１７にクローラベルト１８を巻き掛けた形態としてある。荷箱１後下方には、コンベアベルト１３を上面が後方へ微速駆動することで荷箱１から落下する堆肥３を広範囲に散布する散布装置２を設けてある。１９は作業者が座るシートであり、その前方の２０は操向操作用のサイドクラッチレバーである。荷箱１上部後方では、左右に横架した横ビータ２１の上方乃至前方をカバー２２で覆い、堆肥３が周囲に飛散しないよう構成してある。
【０００７】
本発明の散布装置２の構成は図２に示すように、原動機１２の駆動が荷箱１の左右片側一側に設けた伝動機構（図示せず）を介して散布装置２の入力軸２５に入力され、ベベルギヤ２６，２７を介して回転軸６に伝動する。回転軸６上端部には散布翼４をボルト２８で取着し、入力軸２５に入力された駆動が散布翼４の水平方向回転を行い、本実施例においては散布翼４を時計回りに回転させるようにしてある。散布翼４下側には、散布翼４下面に接近する水平板７を設けてあり、この水平板７から一体的に立設した案内板８を設けてある。このため案内板８の構造が簡単であるとともに、水平板７から一体的に立設した案内板８の回動負荷が少なく、又、回動部分に堆肥が詰まり回動不良を起こす等の不具合もない。該案内板８は、散布翼４の回転軌跡外周縁４ａに沿う散布翼４高さよりも高い形状とし、水平板７と案内板８は回転軸６を中心として一体的に水平方向への回動が可能である。案内板８には一部開口部Ａを設け、回転する散布翼４により散布する堆肥３の散布角度を一定角度に規制してある。水平板７の下面中央には、ギヤ２３を取着し、このギヤ２３に嵌合するギヤ２４はモータＭにより駆動してあり、水平板７が回転軸６を中心に回動可能にしてある。モータＭは正逆回転が可能で、開口部Ａを任意の方向に向けることができる。
【０００８】
次に散布形態について図３、図４、図５を参照に説明する。図３に示すのは、荷箱１後端下方に単一の散布装置２を用いた例である。案内板８の開口部Ａから放出される堆肥は時計回りで回転している散布翼４によってＣの範囲に散布される。この状態からモータＭを駆動させて開口部Ａを機体５の右方向、又は左方向に向けることにより、堆肥の散布方向がＲの範囲、又はＬの範囲となる。このように、堆肥の散布角度は一定のまま、散布方向を容易に変更することができ、作業形態に応じた効率の良い堆肥散布を行うことができる。
【０００９】
図４、図５に示すのは、本発明の散布装置２を左右一対に並設したものである。左右の散布装置２，２中央に設けた分岐板２９は、中央部に落下する堆肥を左右各々の案内板８内方へ振り分けて案内する作用をし、その他の構成は図３に示す散布装置２の構成と同様であり、各々の案内板８が水平板７と一体的に回動自在である。すなわち、左右の散布装置２は開口部Ａの方向を各々変更可能であり、一対の散布装置２の散布方向を変えることによって、狭幅散布Ｄから広幅散布Ｅまでの散布幅調整が可能である。又、例えば図４の右側開口部ＡＲから散布される外方散布ラインＳＲを機体５進行方向と略平行になるよう案内板８を回動させ、左側開口部ＡＬから散布される堆肥をやや機体５左側方向に散布するようにすれば、機体５左側寄りへの散布作業を行うことも可能である。
更に、図５に示すように左右開口部ＡＬ，ＡＲを機体外方の真横方向に向ければ、左右両側方向への散布が可能であり、この散布形態では機体を前後に走行させた場合にも地上に散布した堆肥を走行装置１４が踏むことなく、様々な散布形態での散布作業が可能である。
尚、本発明は、作業者が機体５に乗って作業を行う乗用型の散布車に限定するものではなく、歩行型の散布車に用いた場合においても同様の効果を発揮できるものである。

Function and effect of the present invention
A compost 3 is dropped on a spreading device 2 provided below the packing box 1, and the compost is spread by a plurality of horizontally rotatable spreading wings 4 supported by the spreading device 2 to the front or the rear of the body 5. In the spraying vehicle, a horizontal plate 7 is provided in parallel with the lower surface of the spraying wings 4, and the horizontal plate 7 has an arc-shaped guide having a part opening A in a shape along the rotation trajectory outer peripheral edge 4 a of the spraying wings 4. Since the plate 8 is set up, the compost falling below the horizontally rotating spray blades 4 can be received by the horizontal plate 7 and the guide plate 8 can be horizontally rotated about the rotation axis 6 of the spray blade 4. Therefore, the direction in which compost is sprayed from the opening A can be easily changed without replacing the guide plate 8 with a simple structure. In addition, since the direction of the opening A of the guide plate 8 can be changed at least in the range of 90 degrees to the left and right, the spraying device 2 can be sprayed in the lateral direction, and compost is sprayed on the root of a fruit tree or the like. The spraying direction can be easily changed according to the travel between the fruit tree rows, and efficient spraying according to the work form is possible. Furthermore, it is also possible to perform a spreading operation without the traveling device stepping on the spread compost.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. The compost application vehicle shown in FIG. 1 is a self-propelled application vehicle, in which an operation unit 11 and a motor 12 on which a worker can perform an application operation and a traveling operation are mounted on a front frame 10, and a rear thereof. Is provided with a packing box 1 having a bottom surface formed of a conveyor belt 13 and capable of sending compost backward. A pair of left and right traveling devices 14 driven from the prime mover 12 via a transmission 30 are provided below the packing box 1, and the traveling devices 14 are a front driving sprocket 15, a rear tension wheel 16, and a plurality of grounding rollers. The crawler belt 18 is wound around the wheel 17. Below the packing box 1, there is provided a spraying device 2 for spreading the compost 3 falling from the packing box 1 over a wide area by driving the conveyor belt 13 backward at a very low speed. Reference numeral 19 denotes a seat on which an operator sits, and reference numeral 20 denotes a side clutch lever for steering operation. In the upper rear part of the packing box 1, the upper part or the front part of the horizontal beater 21 laid horizontally is covered with a cover 22 so that the compost 3 does not fly around.
[0007]
As shown in FIG. 2, the configuration of the spraying device 2 of the present invention is such that the driving of the prime mover 12 is connected to the input shaft 25 of the spraying device 2 via a transmission mechanism (not shown) provided on one side of the left and right sides of the packing box 1. The input is transmitted to the rotating shaft 6 via the bevel gears 26 and 27. The spreading wing 4 is attached to the upper end of the rotating shaft 6 with a bolt 28, and the drive input to the input shaft 25 causes the spreading wing 4 to rotate in the horizontal direction. In this embodiment, the spreading wing 4 is rotated clockwise. It is made to let. A horizontal plate 7 approaching the lower surface of the spray wing 4 is provided below the spray wing 4, and a guide plate 8 erected integrally from the horizontal plate 7 is provided. For this reason, the structure of the guide plate 8 is simple, and the rotation load of the guide plate 8 that is integrally provided upright from the horizontal plate 7 is small, and compost is clogged in the rotation part, causing rotation failure. Nor. The guide plate 8 has a shape higher than the height of the spray blades 4 along the outer peripheral edge 4 a of the rotation trajectory 4 a of the spray blades 4, and the horizontal plate 7 and the guide plate 8 integrally rotate about the rotary shaft 6 in the horizontal direction. Is possible. The guide plate 8 is partially provided with an opening A, and the spray angle of the compost 3 sprayed by the rotating spray blades 4 is regulated to a fixed angle. A gear 23 is attached to the center of the lower surface of the horizontal plate 7, and a gear 24 fitted to the gear 23 is driven by a motor M, and the horizontal plate 7 is rotatable around the rotation shaft 6. . The motor M can rotate forward and backward, and the opening A can be directed in any direction.
[0008]
Next, the spraying mode will be described with reference to FIGS. 3, 4, and 5. FIG. FIG. 3 shows an example in which a single spraying device 2 is used below the rear end of the packing box 1. The compost discharged from the opening A of the guide plate 8 is spread in the area C by the spray wings 4 rotating clockwise. By driving the motor M from this state to direct the opening A to the right or left of the body 5, the spreading direction of the compost becomes the range of R or L. In this manner, the spray direction can be easily changed while the spray angle of the compost is kept constant, and efficient spread of the compost according to the work mode can be performed.
[0009]
FIG. 4 and FIG. 5 show the spraying device 2 of the present invention arranged in a pair on the left and right sides. A branch plate 29 provided at the center of the left and right spraying devices 2 and 2 acts to distribute and guide the compost falling to the center to the inside of each of the left and right guide plates 8, and the other components are the spraying device shown in FIG. The configuration is the same as that of the second embodiment, and each guide plate 8 is rotatable integrally with the horizontal plate 7. That is, the directions of the opening portions A of the left and right spray devices 2 can be respectively changed, and by changing the spray direction of the pair of spray devices 2, the spray width can be adjusted from the narrow spray D to the wide spray E. . In addition, for example, the guide plate 8 is rotated so that the outer spray line SR sprayed from the right opening AR in FIG. 4 is substantially parallel to the traveling direction of the machine 5, and the compost sprayed from the left opening AL is slightly machined. If the spraying is performed in the leftward direction, the spraying operation can be performed toward the left side of the machine body 5.
Further, as shown in FIG. 5, if the left and right openings AL and AR are directed to the side of the outside of the machine, the spraying in both the left and right directions is possible. In this spraying mode, even when the machine is run back and forth. Spreading work in various spraying forms is possible without the traveling device 14 stepping on the compost spread on the ground.
Note that the present invention is not limited to a riding type spreader in which a worker rides on the machine body 5 to perform work, and the same effect can be exerted when used in a walking type spreader.
