Description
本発明は、掘取刃の両側にコールターを配し、掘取刃の後方の両側に側壁を有する芋移送用コンベアを設けてあるポテトハーベスターにおいて、掘取刃により掬い上げられたジャガイモやサツマイモなどの各種芋が、コンベアへの移送過程において掘取刃とコールターの隙間から落下しないようにした掘取刃用芋落下防止具及び掘取刃からの芋落下防止具付きポテトハーベスターに関するものである。 The present invention relates to a potato harvester, which has a coulter disposed on both sides of a digging blade and provided with a potato harvesting conveyor having side walls on both sides behind the digging blade. The potato harvester with a pit fall prevention tool for a digging blade and a pit fall prevention tool from the digging blade in which the various kinds of ridges are prevented from dropping from the gap between the digging blade and the coulter during the transfer process to the conveyor.
また、本発明の掘取刃用芋落下防止具は既に使用しているポテトハーベスターにも取り付けられるように、取り付け時の調整範囲を大きくして各種掘取刃の形状などに対応させて簡単に後付けができるようにしたものである。 Further, Toja for potatoes fall prevention device drilling of the present invention are already have as well be attached to port te preparative harvester used, by increasing the adjustment range at the time of mounting to correspond to the shape of the various drilling Toja It can be easily retrofitted.
ジャガイモを収穫する装置としては、特許文献１や特許文献２に示されるように、掘取刃となる掘取体やブレードの側面をカバーする側板を設けたものと、特許文献３乃至特許文献５に示されるように、掘取刃の両側にコールターを設けたものがある。 As an apparatus for harvesting potatoes, as shown in Patent Literature 1 and Patent Literature 2, a digging body serving as a digging blade and a side plate covering the side surface of the blade are provided, and Patent Literatures 3 to 5 are disclosed. As shown in Fig. 1, there is a type in which a coulter is provided on both sides of the digging blade.
前記特許文献１や特許文献２に示されるものは、主に小型の小容量の収穫に使用されるものである。したがって、側板により掘取刃の側面をカバーしても、掘取刃に入るジャガイモや土塊の量も大した量ではないので、掘取刃で掬い上げたものが全部そのまま入るようにしても収穫作業時にそれほどの抵抗とはならない。よって、このような小型のものにおいては、掘取刃で掬い上げたものが全部落下しないように掘取刃の側面には側板が配されているものもある。したがって、この形式者に会っては基本的には掘取刃から掬い上げられたジャガイモは落下しない。 What is shown in the said patent document 1 and the patent document 2 is mainly used for the harvest of small and small capacity. Therefore, even if the side plate covers the side of the digging blade, the amount of potatoes and soil that enter the digging blade is not large. Not so much resistance when working. Therefore, in such a small type, there is also a type in which a side plate is arranged on the side surface of the digging blade so that all the items scooped up by the digging blade do not fall. Therefore, potatoes that are scooped up from the digging blade do not fall when meeting this formalist.
一方、掘取刃の両側にコールターを設けたものは、主に大型のいわゆるポテトハーベスターに属するものに使用されるものであり、基本的には掘取刃で掬い上げられたジャガイモは掘取刃からコンベアへの移送段階ではコールターの存在により掘取刃から落下しないように設計上はなっている。 While those having a Coulter on both sides of the excavation Toja primarily is intended for use in those belonging to the so-called port Te DOO harvesters large, basically scooped by photoetching blade potato diggers In the transfer stage from the cutting blade to the conveyor, the design is such that it does not fall from the cutting blade due to the presence of the coulter.
しかし、掘取刃の両側にコールターを設けた形式のものにあっては、掘取刃とコールターの間やコールターとコンベアの側板との間には、コールターが円板であるが故にどうしても小芋が通過する程度の隙間が生じてしまう。さらに、コールターは使用過程で摩耗することにより徐々にその直径が小さくなる。それゆえ、前記隙間は徐々に大きくなり、通常のサイズのジャガイモまでがその隙間を通過できる程となってしまう。この間隙の大きさはポテトハーベスターの各メーカーの機種によって多少は異なるが、いずれのメーカーの機種であっても、コールターと掘取刃の間に間隙はある。 However, in the type in which the coulters are provided on both sides of the digging blade, the coulter is a disc between the digging blade and the coulter and between the coulter and the side plate of the conveyor. A gap to the extent of passing will occur. Furthermore, the diameter of the coulter gradually decreases as it wears during use. Therefore, the gap gradually increases, so that even normal size potatoes can pass through the gap. The size of the gap varies somewhat depending on the type of each manufacturer of port Te DOO harvester, even model of any manufacturer, the clearance between Coulter and photo blade is.
したがって、この隙間を放置しておくと、折角掘取刃で掬い上げたジャガイモがこの隙間から落下してしまうことになる。しかも、その上にコンベアに載った土塊がロットの目よりふるい落とされ、これが先に落下したジャガイモに覆いかぶさり完全に見えなくなってしまう状態となり、後で人手で拾うことも困難な状態となる。 Therefore, if this gap is left unattended, the potatoes that have been scooped up by the corner digging blade will fall from this gap. In addition, the earth lump placed on the conveyor is screened out from the eyes of the lot, and it is covered with the potatoes that have fallen first, so that it becomes completely invisible, and it becomes difficult to pick it up manually later.
落下したジャガイモは、そのまま放置しておくと次年度に発芽し雑草化して次の作物の妨げとなる。そして、雑草化した芋の抜き取り作業には多大な労力と経費がかさみ、農家にとっては大きな経済的な負担となっている。 If the potatoes that fall are left as they are, they will germinate and become weeds in the following year, hindering the next crop. In addition, it takes a lot of labor and expense to extract weeded straw, which is a big economic burden for farmers.
本発明は、かかる事情に鑑みてなされたものであり、その目的とするところは、掘取刃の両側にコールターを有するポテトハーベスターにおいて、掘取刃で掬い上げたジャガイモが途中で落下せずに全部がコンベアに移送されるようにした掘取刃とこの掘取刃を備えたポテトハーベスターを提供することにある。また、既に使用されている各種のポテトハーベスターに使用することができるように、その構成を工夫したものである。 The present invention has been made in view of such circumstances, it is an object of excavation in port te preparative harvester having a Coulter on both sides of the Toja, not fall prematurely potato scooped by photo blade in that all provide a port te bets harvester having the digging Toja and diggers Toja was to be transferred to the conveyor without. Also, as can be used in various ports Te bets harvester that is already in use, it is obtained by devising the configuration.

First, an embodiment of a dredging blade dredging prevention tool according to the present invention will be described with reference to FIGS.
FIG. 1 is a perspective view showing a state in which a dredging fall guard for a digging blade according to the present invention is assembled. FIG. 2 is a perspective view showing the attachment relationship between the three members of the digging blade dredging fall prevention tool of the present invention and the digging blade A. FIG. FIG. 3 is a perspective view showing a state in which the cutting tool for digging blade according to the present invention is attached to the digging blade A. FIG. FIG. 4 is a perspective view showing another example of the dredger fall prevention tool for digging blades of the present invention.
As shown in FIG. 2, the digging blade dredging fall prevention tool is constituted by three members, a fall prevention plate 1, an adjustment plate 2, and a side wall fixing plate 3. These are basically made of stainless steel, but need not be made of metal as long as they have a certain level of strength.
落下防止板１は斜辺４と長辺５と短辺６からなる略直角三角形形状に形成してある。但し、この略直角三角形の形状はそれほど厳密なのではない。そして、長辺５を数ｃｍ延出して直角に折り曲げて掘取刃取付部７とし、ボルト用の透孔８を形成する。なお、掘取刃取付部７は、長辺５付近をそのまま折り曲げてもよく、また折り曲げ角度を調整できるようにしておいてもよい。 The fall prevention plate 1 is formed in a substantially right triangle shape having a hypotenuse 4, a long side 5 and a short side 6. However, the shape of this substantially right triangle is not so precise. Then, the long side 5 is extended several centimeters and bent at a right angle to form a digging blade mounting portion 7 to form a through hole 8 for a bolt. The digging blade mounting portion 7 may be bent in the vicinity of the long side 5 as it is, or the bending angle may be adjusted.
短辺６にはこの短辺６と斜辺４がなす頂部９より１ｃｍ以上下がった位置より折り曲げ又は折り曲げ可能に調整板２取付用の調整板取付部１０を延出し、この調整板取付部１０には前記短辺６と並行にボルト用の長孔１１を所望数形成する。調整板取付部１０を折り曲げたり折り曲げ可能とするのは、取り付けるポテトハーベスターに応じて取り付けた結果芋が落下するような隙間が生じないようにするためである。調整板取付部１０のボルト用孔を長孔１１とするのは、取り付けるポテトハーベスターに応じて、調整板２の取付位置を上下方向に調整して最適な位置にセットできるようにするためである。 An adjustment plate mounting portion 10 for mounting the adjustment plate 2 is extended to the short side 6 so that it can be bent or bent from a position lower than 1 cm from the top portion 9 formed by the short side 6 and the hypotenuse 4. Forms a desired number of long holes 11 for bolts in parallel with the short side 6. The reason why the adjustment plate attachment portion 10 can be bent or bent is to prevent a gap from dropping as a result of attachment according to the potato harvester to be attached. The reason why the bolt hole of the adjusting plate mounting portion 10 is the long hole 11 is to adjust the mounting position of the adjusting plate 2 in the vertical direction according to the potato harvester to be installed and set it at the optimum position. .
また、頂部９より２ｃｍ以上下がった位置より調整板取付部１０を延出するのは、ジャガイモの蔓や雑草などの不純物が調整板取付部１０の折り曲げた角に溜るのを防止し、流れをよくするためである。これは、本願の発明者が種々の実験をした結果このような現象が生じることを問題点として確認し、そしてその解決策としてこのような構造を考え出したものである。 Further, extending the adjustment plate mounting portion 10 from a position that is 2 cm or more lower than the top portion 9 prevents impurities such as potato vines and weeds from accumulating at the bent corners of the adjustment plate mounting portion 10, This is to make it better. This is because the inventors of the present application have confirmed that such a phenomenon occurs as a result of various experiments, and have come up with such a structure as a solution.
すなわち、図４の点線で示すように落下防止板１の斜辺４’と調整板取付部１０を同一高さで連続的に形成し、調整板取付部１０のところで折り曲げると、落下防止板１の斜辺４に沿って昇ってきた蔓や雑草この折り曲げた曲折部Ｘに引っ掛かり、この折り曲げた曲折部Ｘに引っ掛かった蔓や雑草が瞬く間に堆積してしまうのである。通常、ポストハーベスターは掘取刃Ａの幅よりもコンベアＢの幅が広いので、掘取刃ＡとコンベアＢの側壁Ｃを連結するためには、このように調整板取付部１０で折り曲げる必要があるのである。 That is, as shown by the dotted line in FIG. 4, the hypotenuse 4 ′ of the fall prevention plate 1 and the adjustment plate attachment portion 10 are continuously formed at the same height and bent at the adjustment plate attachment portion 10. The vines and weeds that have risen along the hypotenuse 4 are caught in the bent portion X, and the vines and weeds caught in the bent portion X are accumulated in an instant. Usually, since the width of the conveyor B is wider than the width of the digging blade A in the post harvester, in order to connect the digging blade A and the side wall C of the conveyor B, it is necessary to bend the adjustment plate mounting portion 10 in this way. There is.
一方、落下防止板１の斜辺４に対して調整板取付部１０を２ｃｍ以上下げておくと、落下防止板１の斜辺４に沿って昇ってきた蔓や雑草などは頂部９まで達すると、その先には沿って上昇する部材がないので、蔓や雑草は頂部９で落下防止板１から自動的に抜け落ち、落下防止板１から外れた蔓や雑草は、コンベアＢ上に落下して移送されることになる。したがって、ジャガイモの蔓や雑草が落下防止板１の折れ曲がったところで滞留することがないのである。 On the other hand, if the adjustment plate mounting portion 10 is lowered by 2 cm or more with respect to the hypotenuse 4 of the fall prevention plate 1, vines and weeds rising along the hypotenuse 4 of the fall prevention plate 1 reach the top 9, Since there is no member that rises along the tip, the vines and weeds automatically fall off the fall prevention plate 1 at the top 9, and the vines and weeds that have come off the fall prevention plate 1 fall on the conveyor B and are transferred. Will be. Therefore, potato vines and weeds do not stay where the fall prevention plate 1 is bent.
なお、調整板取付部１０を頂部９より下げる距離としては２ｃｍ以上あればよいが、基本的には４ｃｍ〜５ｃｍが最適である。
本願の掘取刃用芋落下防止具は、このジャガイモの蔓や雑草などが途中で滞留しないような構造にしたところに大きな特徴を有している。
In addition, although it should just be 2 cm or more as a distance which lowers the adjustment board attaching part 10 from the top part 9, 4 cm-5 cm are optimal optimally.
The digging blade dredging fall prevention tool of the present application has a great feature in a structure that prevents the potato vines, weeds, etc. from staying on the way.
また、図４に示すように、落下防止板１の斜辺４を、短辺６と交叉する頂部９よりそのまま棒状に２ｃｍ〜５ｃｍ突出させた棒状部Ｙを設けておくと、さらに蔓や雑草などの滞留を防止する効果が大きくなる。なお、斜辺４全長にわたり棒状部材を配し、その先端をそのまま棒状部Ｙとなるようにしてもよい。 In addition, as shown in FIG. 4, if a rod-like portion Y is formed by projecting the hypotenuse 4 of the fall prevention plate 1 from the top 9 crossing the short side 6 as it is in the shape of a rod 2 cm to 5 cm, a vine, weed, etc. The effect of preventing the retention of is increased. Note that a bar-shaped member may be provided over the entire length of the hypotenuse 4 so that the tip of the bar-shaped part Y is used as it is.
調整板２は略平行四辺形に形成する。但し、この形状はそれほど厳密なものではない。そして、任意の一辺の近傍には前記調整板取付部１０の長孔１１の位置に合わせてボルト用の透孔８を形成する。この辺の長さは、基本的には前記調整板取付部１０の長さと同じ程度とする。また、このボルト用の透孔８を形成した辺に対向する辺の近傍には残りの他の二辺と並行な向きに所望数のボルト用の長孔１１を形成し、側壁固定板３取付用の側壁固定板取付部１２とする。 The adjustment plate 2 is formed in a substantially parallelogram. However, this shape is not so strict. A bolt through hole 8 is formed in the vicinity of an arbitrary side in accordance with the position of the long hole 11 of the adjustment plate mounting portion 10. The length of this side is basically the same as the length of the adjustment plate mounting portion 10. Further, in the vicinity of the side opposite to the side where the bolt through-hole 8 is formed, a desired number of bolt long holes 11 are formed in the direction parallel to the other two sides, and the side wall fixing plate 3 is attached. The side wall fixing plate mounting portion 12 is used.
側壁固定板取付部１２のボルト用孔を長孔１１とするのは、取り付けるポテトハーベスターに応じて、側壁固定板２の取付位置を前後方向に調整して最適な長さでセットできるようにするためである。 The bolt hole of the side wall fixing plate mounting portion 12 is made into the long hole 11 so that the mounting position of the side wall fixing plate 2 can be adjusted in the front-rear direction according to the potato harvester to be set at an optimum length. Because.
側壁固定板３は略平行四辺形に形成する。但し、この形状はそれほど厳密なものではない。そして、任意の一辺の近傍には前記調整板２の側壁固定板取付部１２の長孔１１の位置に合わせてボルト用の透孔８を形成する。また、このボルト用の透孔８を形成した辺と並行に任意箇所で折り曲げ又は折り曲げ可能とする。そして、このボルト用の透孔８を形成した辺に対向する辺の近傍にはコンベアＢの側壁Ｃへ固定するための所望数のボルト用の透孔８を形成する。 The side wall fixing plate 3 is formed in a substantially parallelogram. However, this shape is not so strict. A bolt through hole 8 is formed in the vicinity of an arbitrary side in accordance with the position of the long hole 11 of the side wall fixing plate mounting portion 12 of the adjustment plate 2. Further, the bolt can be bent or bent at an arbitrary position in parallel with the side where the through hole 8 for the bolt is formed. Then, a desired number of bolt through holes 8 for fixing to the side wall C of the conveyor B are formed in the vicinity of the side opposite to the side where the bolt through holes 8 are formed.
側壁固定板３を折り曲げ又は折り曲げ可能とするのは、取り付けるポテトハーベスターに応じて、側壁固定板２の取付位置を調整して最適な位置にセットできるようにするためである。したがって、各長孔１１の長さや折り曲げ角度の調整範囲を大きくしておけば、それだけ汎用性が高まることになる。 The reason why the side wall fixing plate 3 can be bent or bent is to adjust the attachment position of the side wall fixing plate 2 in accordance with the potato harvester to be attached so that the side wall fixing plate 3 can be set to an optimum position. Therefore, if the adjustment range of the length of each long hole 11 and a bending angle is enlarged, versatility will increase so much.
そして、これら落下防止板１と、調整板２と、側壁固定板３を掘取刃Ａに取り付けるに際しては、最初に落下防止板１を掘取刃取付部７の透孔８を利用して掘取刃Ａにボルトにより取り付ける。次に落下防止板１の調整板取付部１０の長孔１１に調整板２の透孔８を合致させてそこにボルトを通して仮固定して取り付ける。次に、調整板２の側壁固定板取付部１２の長孔１１に側壁固定板３の透孔８を合致させてそこにボルトを通して仮固定する。そして、側壁固定板８の他辺側の透孔８をコンベアＢの側壁Ｃに形成したボルト用孔に合致させてそこにボルトを通して仮固定する。その後調整板２と側壁固定板３の角度や位置や長さなどを順次調整し、最終的にはこれらを固定状態とすることにより取付が完了する。 When the fall prevention plate 1, the adjustment plate 2, and the side wall fixing plate 3 are attached to the digging blade A, the fall prevention plate 1 is first excavated using the through holes 8 of the digging blade attachment portion 7. Attach to the blade A with bolts. Next, the through hole 8 of the adjustment plate 2 is matched with the long hole 11 of the adjustment plate mounting portion 10 of the fall prevention plate 1 and is temporarily fixed and attached thereto through a bolt. Next, the through hole 8 of the side wall fixing plate 3 is matched with the long hole 11 of the side wall fixing plate mounting portion 12 of the adjusting plate 2 and is temporarily fixed through a bolt. Then, the through holes 8 on the other side of the side wall fixing plate 8 are matched with the bolt holes formed on the side walls C of the conveyor B, and the bolts are temporarily fixed therethrough. Thereafter, the angle, position, length, and the like of the adjustment plate 2 and the side wall fixing plate 3 are sequentially adjusted, and finally the mounting is completed by setting them in a fixed state.
あるいは、取り付けるポテトハーベスターの取り付け位置などがわかっている場合には、先に図１に示すように落下防止板１の調整板取付部１０の長孔１１に調整板２の透孔８を合致させてそこにボルトを通して固定し、同様に調整板２の側壁固定板取付部１２の長孔１１に側壁固定板３の透孔８を合致させてそこにボルトを通して固定する。そして、最終的に図３に示すように落下防止板１の掘取刃取付部７の透孔８を利用して掘取刃Ａにボルトにより取り付けるようにしてもよい。 Alternatively, when the attachment position of the potato harvester to be attached is known, the through hole 8 of the adjustment plate 2 is aligned with the long hole 11 of the adjustment plate attachment portion 10 of the fall prevention plate 1 as shown in FIG. Then, the bolts are fixed through the bolts. Similarly, the through holes 8 of the side wall fixing plate 3 are matched with the long holes 11 of the side wall fixing plate mounting portion 12 of the adjusting plate 2 and are fixed through the bolts. And finally as shown in FIG. 3, you may make it attach to the digging blade A with a volt | bolt using the through-hole 8 of the digging blade attachment part 7 of the fall prevention plate 1. FIG.
