Abstract

<P>PROBLEM TO BE SOLVED: To provide an inexpensive partially fertilizing apparatus capable of carrying out partially fertilizing operation even under every soil condition. <P>SOLUTION: The partially fertilizing apparatus is provided with a digging and fertilizing portion having a machine frame, and a digging and fertilizing part attached to the machine frame and having a digging-driving case rotating around an axial direction crossing the traveling direction of a machine body, helical digging tines radially extended from the digging-driving case, and rotating around an axial direction in the extended directions, and fertilizing pipes installed parallel to the digging tines, and having the interiors formed into cylindrical shapes, and tip parts having fertilizing opening parts. As a result, a prescribed digging depth can be provided even at a field having a hard soil condition, and a fertilizing operation in the soil can smoothly be carried out because digging resistance is reduced and soil-crushing performance is improved by using the digging tines formed into the helical shapes in a process for digging a hole. <P>COPYRIGHT: (C)2005,JPO&NCIPI

【0002】
【従来の技術】
従来技術として、本体の進行方向に対して交差方向を取るように本体に取付られるとともに駆動体回転軸の回転方向と同方向に回転される掘削刃回転軸と、掘削刃回転軸から放射状をとるように掘削刃回転軸に基部が取り付けられ掘削刃回転軸を回転中心として回転されるとともに、基部から先端方向に延長される仮想中心線を回転中心として回転される螺旋刃と、掘削刃回転軸を回転中心として回転される螺旋刃の回転方向後方に掘削刃回転軸から放射状をとるように掘削刃回転軸に基部が取り付けられるとともに、筒状からなり内部に供給される肥料を先端から放出する肥料放出管とから構成され、螺旋刃と肥料放出管すなわち施肥パイプを回転させながら進行し、螺旋刃を土壌に対し局所的に掘削しながら施肥パイプを突き刺し、パイプ内を通過する肥料を土中に施肥する施肥装置が公知である。(特許文献1)

【0004】
【発明が解決しようとする課題】
しかしながら、従来技術の構成では、螺旋刃はコイル状のコイル刃にて構成しされるため高価である。又、コイル刃の先端部のみを鋭角とし中間部は円筒状の曲面であるため、土壌条件の固い圃場では、掘削抵抗が大きく所定の砕土深さが得られず、肥料供給管を土中に突き刺すことができず施肥作業が行えないことがあった。
【0005】
又、エンジンや走行台車などを備え自走型の構成としているため高価な局所施肥装置であった。
【0006】
そこで本発明は、あらゆる土壌条件においても適正な局所施肥作業が行え、且つ、安価な局所施肥装置を提供することを目的とする。
【0007】
【課題を解決するための手段】
上記課題を解決するために、機枠と、この機枠に取付けられ、機体の進行方向に対し交差する方向を回転中心に回転する掘削駆動ケースと、この掘削駆動ケースより放射状に延設され、延設方向を回転中心とし自転する螺旋状の掘削爪と、この掘削爪に併設され、内部を筒状とし先端部に施肥開口部を開口した施肥パイプとからなる掘削施肥部を設けたことことにより、掘削穴を開口する工程において螺旋状とした掘削爪を用いたため掘削抵抗が少なくなり砕土性も向上するので、土壌条件の固い圃場においても所定の掘削深さとし土中施肥作業がスムーズに行える。
【0008】
又、機枠に、トラクタへ装着可能とするトラクタ装着装置を設けたことにより、トラクタ作業機として局所施肥装置を構成することができ、エンジンや走行台車を必要としないため安価で提供することができる。

【0011】
機枠1は、平面視コの字状としたパイプ体にて構成されたパイプフレーム11と、このパイプフレーム11の一端部に、トラクタ後部へ装着するトラクタ装着装置2を取り付けるための装着ブラケット12が設けられる。又、パイプフレーム11には、前記装着ブラケット12を中心とし、進行方向Fに対し直交する外方側面方向に貯留供給部3を支持する貯留部ブラケット13と、この貯留部ブラケット13よりさらに外方側面方向に掘削施肥部4を回転自在に支持する掘削部支持ブラケット14が設けられる。
【0012】
トラクタ装着装置2は、トラクタ後部に備えられる作業機昇降装置に装着するための装着マスト21と、トラクタPTO軸より回転駆動力が入力される入力軸22と、この入力軸22より貯留供給部3及び掘削施肥部4へ回転動力を伝達するドライブシャフト23から構成される。
【0013】
3の貯留供給部は、前記トラクタ装着装置2に備えたドライブシャフト23が連結される施肥駆動ケース31と、肥料を貯留するホッパ32と、ホッパ32の底面に開口部を形成するシャッタ33と、シャッタ33の上面に配置され、施肥駆動ケース31にて駆動され、ホッパ32内を回転するアジテータ34と、シャッタ33にて形成されたシャッタ開口部より吐出される肥料を掘削施肥部4へ案内する案内管35から構成される。
【0014】
31の施肥駆動ケースは、前記ドライブシャフト23が連結されるとともに貫通させ配置された施肥駆動軸31aと、内部に備えたウォームギヤ31bと、上方に突設させたアジテータ駆動軸31cにて構成され、施肥駆動軸31aを進行方向Fに対し直交させ配置される。
【0015】
ホッパ32は略逆四角錐状からなり、肥料を貯留可能とする。シャッタ33は、開口部を有した底板33aと、底板33aの下面をスライド自在としたシャッタ板33bからなり、底板33aの開口部とシャッタ板32bの重合にてシャッタ開口部が形成され、重合量に応じシャッタ開度量すなわちシャッタ開口部の開口量が調節可能で、シャッタ開度量に応じてホッパ32内に貯留した肥料の吐出量が決定される。
【0016】
アジテータ駆動軸31cの先端部に連結されシャッタ33の上面に配置されるアジテータ34は、ホッパ32内を回転するこで肥料のシャッタ開口部からの吐出をスムーズに行う。
【0017】
35の案内管は、シャッタ33にて形成されるシャッタ開口部と掘削施肥部4とを連結するもので、シャッタ33のシャッタ開度量に応じ吐出される肥料が案内管35を介して掘削施肥部4へ供給される。
【0018】
掘削施肥部4は、前記機枠1の掘削部支持ブラケット14にて回転可能に支持される掘削駆動ケース41と、掘削駆動ケース41より放射状に延設させた螺旋状の掘削爪42と、掘削爪42に併設された施肥パイプ43と、この施肥パイプ43へ肥料を供給する供給ドラム44にて構成される。
【0019】
掘削駆動ケース41は、一端部を、進行方向Fに対し直交する方向に向け施肥駆動軸31aを備えた施肥駆動ケース31の外方側面に回転自在に嵌合され、他端を機枠1の掘削部支持ブラケット14にて回転可能に支持される。内部には施肥駆動軸31aと連結される掘削駆動軸41aとベベルギヤ41bが設けてある。
【0020】
掘削爪42は、螺旋状に形成されてある。この掘削爪42は、基部を前記掘削駆動ケース41のベベルギヤ41bにて回転駆動される爪軸41cに取付け、放射状に延設される。延設された掘削爪42は、延設方向を回転中心とし自転し、回転方向に対向する対向縁には鋭角とした刃部42aが設けられている。
【0021】
施肥パイプ43は、円筒状で先端部に円錐状の突刺部43aと、機体進行方向Fに対し交差する方向に施肥開口部43bを有してなり、内部には、図3に示すように施肥パイプ43の長手方向中心に、前記掘削駆動ケース41より延設され回転する繰出軸43cが設けてあり、この繰出軸43cの先端部には繰出軸43cの回転中心より放射状に設けた排出板43dと、排出板43dより掘削駆動ケース41側の内方に螺旋状としたオーガ43eからなる排出体が設けてある。
【0022】
本実施例では、図示されるように、螺旋状とした掘削爪42を放射方向に側面視にて一対設け、この一対の掘削爪42の中間に施肥パイプ43を併設し、この一対の掘削爪42と中間に併設した施肥パイプ43を掘削ユニットとし、この掘削ユニットを掘削駆動ケース41を挟んで対向させるとともに90°位相させ、2列に並べて計4個配置する。
【0023】
44の供給ドラムは、円錐台カバー44aと、第1供給管44b及び第2供給管44cから構成され、円錐台カバー44aの径大面が掘削駆動ケース41に取付けられ、前記貯留供給部3の案内管35の先端部が重合する。径大面より延設される第1供給管44bは、ホッパ32側内方に備えた掘削ユニットの施肥パイプ43の上部と連結され、第2供給管44cは外方に備えた掘削ユニットの施肥パイプ43の上部と連結される。
【0024】
駆動伝達及び作用は、図2及び図3に示すように、トラクタ装着装置2に設けた入力軸22へトラクタPTO軸よりユニバーサルジョイントを介し、回転駆動力が入力される。入力された回転駆動力は、ドライブシャフト23を介し、貯留供給部3に備えた施肥駆動ケース31の施肥駆動軸31aと、施肥駆動軸31aに連結された掘削駆動ケース41の掘削駆動軸41aへ伝達される。
【0025】
先ず、施肥駆動軸31aは、伝達された回転駆動力をウォームギヤ31bにて減速し、上方へ突設させたアジテータ駆動軸31cを回転させ、アジテータ駆動軸31cの上方先端部に取付けたアジテータ34を回転させる。
【0026】
回転駆動されたアジテータ34は、ホッパ32内に貯留した肥料をシャッタ33にて形成したシャッタ開口部よりスムーズに吐出させることができ、シャッタ開口部より吐出された肥料は案内管35を介し掘削施肥部4の供給ドラム44へ供給される。
【0027】
又、掘削駆動軸41aは、伝達された回転駆動力にて図4に示すように、掘削駆動ケース41を進行方向Fに対し順方向となるf1方向に回転させるとともに、掘削駆動ケース41内部に備えたベベルギヤ41bを介し、掘削駆動ケース41より放射状に延設された螺旋状の掘削爪42をf2方向へ自転させ、さらに施肥パイプ43の内部に設けた繰出軸43cを回転させ、先端部に設けた排出板43d及びオーガ43eからなる排出体を回転させる。
【0028】
施肥作業は、機体を進行させるのと同時に掘削爪42がf2方向に自転しながら掘削駆動ケース41がf1方向へ回転する。掘削駆動ケース41の回転中心は、機体進行方向Fとともに水平移動されるので掘削爪42及び施肥パイプ43は圃場を局所的に掘削する。
【0029】
自転する掘削爪42の回転方向に対向する対向縁に刃部42aを設けてあるので、土壌条件の固い圃場においても掘削抵抗を少なくすることができるとともに砕土性も向上する。又、施肥パイプ43の先端部に設けた突刺部43aは施肥パイプ43を土中へ刺し込み易くしている。
【0030】
案内管35を介し供給ドラム44に供給された肥料は、供給ドラム44の円錐台カバー44aに一時的に貯留される。供給ドラム44が掘削駆動ケース41とともに第1供給管44b及び第2供給管44cの開口部が肥料の貯留部にくると、肥料は第1供給管44b及び第2供給管44cを通過し、施肥パイプ43内にそれぞれ供給される。
【0031】
施肥パイプ43内に供給された肥料は自然落下し、施肥パイプ43の内部先端すなわち施肥開口部43bの内側に設けた排出板43d、及びオーガ43eからなる排出体にて、進行方向に対し交差する方向へ開口させた施肥開口部43bより強制的に土中へ放出され施肥される。
【0032】
施肥開口部43bを進行方向に対し交差する方向へ開口させたことにより、施肥パイプ43内への土の入り込みが軽減される。排出板43d及びオーガ43eからなる排出体は強制的に肥料を土中に放出するのと同時に、施肥パイプ43内へ入り込もうとする土を排除する役目もする。
【0033】
【発明の効果】
以上のように構成された局所施肥装置はの掘削爪は、土壌条件の固い圃場においても回転方向に対向する対向縁を鋭角としているため、掘削抵抗が少なく砕土性が向上し、施肥パイプが土中へ刺し込み易くなりスムーズに局所施肥作業が行える。
【0034】
又、トラクタ作業機として構成されているため、従来のような自走が他の局所施肥装置に比べエンジンや走行台車を必要としないので、安価で提供することができる。

The fertilizer supplied to the supply drum 44 via the guide tube 35 is temporarily stored in the truncated cone cover 44a of the supply drum 44. When the supply drum 44 and the excavation drive case 41 together with the opening of the first supply pipe 44b and the second supply pipe 44c reach the storage part of the fertilizer, the fertilizer passes through the first supply pipe 44b and the second supply pipe 44c, and the fertilizer is applied. Each is supplied into the pipe 43.
[0031]
The fertilizer supplied into the fertilizer pipe 43 falls naturally, and intersects in the traveling direction at the inner tip of the fertilizer pipe 43, that is, a discharge plate 43d provided inside the fertilizer opening 43b, and a discharge body including the auger 43e. The fertilizer is forcibly discharged into the soil through the fertilizer application opening 43b opened in the direction, and fertilized.
[0032]
Since the fertilizer application opening 43b is opened in a direction intersecting the traveling direction, entry of soil into the fertilizer application pipe 43 is reduced. The discharge body composed of the discharge plate 43d and the auger 43e forcibly discharges the fertilizer into the soil, and at the same time, serves to eliminate the soil that tries to enter the fertilizer pipe 43.
[0033]
【The invention's effect】
The excavation claw of the local fertilizer applicator constructed as described above has an acute angle on the opposing edge in the rotating direction even in a field with hard soil conditions, so that excavation resistance is small, soil breaking property is improved, and the fertilizer pipe is soiled. It is easy to stab inside and can perform local fertilization work smoothly.
[0034]
In addition, since it is configured as a tractor working machine, self-propelled as in the related art does not require an engine or a traveling trolley as compared with other local fertilizers, so that it can be provided at low cost.
