Description
本発明は、一芽苗補植用穴あけ器に関し、更に詳しくは、好ましくはサトウキビの補植に有用な手作業式の一芽苗補植用穴あけ器に関する。 The present invention relates to a single-plant seedling transplanter, and more particularly to a manually operated single-plant seedling transplanter useful for sugarcane supplemental planting.
サトウキビの種苗の植え付けは、その作付け場所や面積に依存して、通常、その種苗を一列に複数株ごと複数列で土壌に植え付けを行う。この際、全てがきれいに萌芽すれば何ら問題は生じないが、多くの場合には、これらのうちのいくらかは萌芽しないことがある。即ち、欠株が生ずる。これを放置しておけば、当然収量が低下するので、通常、補植が実施される。この補植の方法として、サトウキビの一芽苗を欠株部分に植え付けることがなされている。 Depending on the planting location and area, sugarcane seedlings are usually planted on the soil in multiple rows in multiple rows. At this time, if everything germinates well, no problem occurs, but in many cases, some of these may not germinate. That is, a stock loss occurs. If this is left unattended, the yield will naturally decrease, so supplementary planting is usually carried out. As a method for this supplemental planting, a sugarcane shoot is planted in the missing part.
従来、この補植方法としては、クワで土壌に穴を掘って一芽苗を補植する方法、あるいは、図１２に示したような補植棒を使用して土壌に穴を掘って補植する方法が採用されていた。しかし、欠株は、圃場によってはかなりの数となることもあり、農家の人々が、補植をこれらの方法により人力で実施するには相当の労力が必要であった。 Conventionally, as this supplemental planting method, a method of digging a hole in the soil with mulberry to supplement a single seedling, or a planting hole as shown in FIG. The method to do was adopted. However, the number of strains could be considerable depending on the field, and it took considerable effort for farmers to implement supplementary planting by these methods.
このような問題を解決するために、種々の方法が提案されている。例えば、懸垂自在な筒体の上部開口部の上方に把手を配し、その把手に対し回動自在に付設したレバーを、把手と共に強く握ると筒体の下端開口部に設けられた嘴状の穿孔機が開き、放すと閉じるよう該穿孔機を上記レバーに対しワイヤ機構を介し開閉自在に連動せしめたことを特徴とするポット苗用補植機（特許文献１）、懸垂自在な筒体の上部開口から苗を投入し、該筒体の下端に取り付けた植え孔形成口を地中で開放して、形成された植え孔に苗を落下させる苗補植機であって、前記筒体を伸縮自在に形成し、該筒体に前記植え孔形成口の開閉を電動駆動する駆動部を装着し、前記駆動部の開閉操作スイッチを前記筒体上部の把持部に設け、前記駆動部に導通する電源を作業者の腰部に搭載可能にしたことを特徴とする苗補植機（特許文献２）、及び、上下に長い筒状体の下端部から苗を繰り出して圃場へ植え付ける苗植付機において、前記下端部に植え付けた苗の周辺の土壌を側方から押さえて鎮圧する鎮圧手段を設けたことを特徴とする苗植付機（特許文献３）等が知られている。これらの機器にあっては、確かに労力を軽減でき、穴あけと同時に補植等を実施し得るが、例えば、サトウキビの一芽苗では、十分な活着が得られないことが多く、再度、上記のような従来法で補植をやり直さなければならない等の問題があった。また、これらの機器は比較的高価であるという問題もあった。 In order to solve such a problem, various methods have been proposed. For example, when a handle is arranged above the upper opening of a cylindrical body that can be suspended and a lever attached to the handle is squeezed together with the handle, the hook-like shape provided at the lower end opening of the cylinder A pot seedling transplanter (patent document 1) characterized in that the punching machine is opened and closed and linked to the lever through a wire mechanism so as to be opened and closed. A seedling supplemental planting machine that inserts seedlings from an upper opening, opens a hole for forming a planting hole attached to the lower end of the cylindrical body in the ground, and drops the seedling into the formed planting hole. The tube is formed to be extendable and attached to the cylinder, and a drive unit that electrically drives opening and closing of the planting hole forming port is mounted. Seedling transplanting machine (Patent) 2) And, in the seedling planting machine that feeds seedlings from the lower end of the tubular body that is long in the vertical direction and plantes them in the field, the suppression means for pressing down the soil around the seedlings planted in the lower end from the side. There is known a seedling planting machine (Patent Document 3) characterized by providing In these devices, labor can certainly be reduced, and supplemental planting etc. can be carried out at the same time as drilling, but for example, with a single shoot of sugarcane, sufficient survival is often not obtained, and again, There was a problem such as having to redo supplementary planting by the conventional method. In addition, there is a problem that these devices are relatively expensive.
人力で実施し得る安価な補植機器としては、例えば、縦向きのパイプ６００の下端が開放されて挿入口６００ａとなり、その側面に排出口６００ｂが設けられている補植用作孔具が提案されている（特許文献４）。該発明の補植用作孔具は、詳細には、図１３に示されたようなものである。該補植用作孔具は、孔１００ｂよりもやや小径のパイプ６００の上端にハンドル７００がＴ字型に固定されており、パイプ６００の下端が開放されて挿入口６００ａが設けられ、側面に排出口６００ｂが設けられている。パイプ６００の側面のやや上の位置に鈎型の案内溝８００を設け、押出棒９００をパイプ６００内に上下に移動できるように取付け、これに固定したピン９００ａが案内溝８００に入っている。そして、ピン９００ａを案内溝８００の上部の水平部８００ａに位置させると、押出棒９００の下端が排出口６００ｂよりも上方に来るようになっており、ピン９００ａを垂直部８００ｂの下端に位置させると、押出棒９００の下端が挿入口６００ａよりもやや下に突出するようになっている。そして、床土２００に孔を開けるときは、ピン９００ａを水平部８００ａに掛け止めて用いるものである。即ち、苗の育っていないポット１００ａが有ると、パイプ６００を孔１００ｂから床土２００内に、所定の深さに差込む。すると、挿入口６００ａの下の土がパイプ６００内に入る。そのパイプ６００をポット１００ａから引抜くと、パイプ６００内の円筒状の土は、下端で引きちぎられ、パイプ６００と共にポット１００ａから引上げられる。なお、粘性の高い床土２００については、パイプ６００をポット１００ａに差し込んだ後、そのパイプ６００の上を前後左右に少し傾けたり、パイプ６００を少し回すと、パイプ６００内の円筒状の土の下端が切れる。続いて、苗が育っていない次のポット１００ａに同じようにパイプ６００を差込む。すると、パイプ６００が保持している上記の円筒状の土が、次の土で押上げられて排出口６００ｂからパイプ６００外に排出される。このように、パイプ６００を孔１００ｂから床土２００内に押込むのみで床土２００に連続的に孔２００ｂを作ることができる。そして、その孔２００ｂは、土が円筒状に取除かれており、従来のように押固められていないので、底が軟くて補植される苗が良好に活着する。パイプ６００内に詰った土や、作業の最後にパイプ６００内に残った土は、ピン９００ａを、垂直部８００ｂ内で上から下に向けて移動させると、押出棒９００の下端で押下られて挿入口６００ａから押出される。 As an inexpensive planting device that can be implemented manually, for example, a planting tool for planting in which the lower end of the vertically oriented pipe 600 is opened to form an insertion port 600a and a discharge port 600b is provided on the side surface is proposed. (Patent Document 4). In detail, the hole making tool for supplemental transplantation according to the present invention is as shown in FIG. In this hole-planting tool, a handle 700 is fixed to the upper end of a pipe 600 having a diameter slightly smaller than that of the hole 100b, the lower end of the pipe 600 is opened, an insertion port 600a is provided, and a side surface is provided. A discharge port 600b is provided. A saddle-shaped guide groove 800 is provided at a position slightly above the side surface of the pipe 600, and the push rod 900 is attached to the pipe 600 so that it can be moved up and down. When the pin 900a is positioned at the horizontal portion 800a at the top of the guide groove 800, the lower end of the push rod 900 is positioned above the discharge port 600b, and the pin 900a is positioned at the lower end of the vertical portion 800b. And the lower end of the extrusion rod 900 protrudes slightly below the insertion port 600a. And when making a hole in the floor soil 200, the pin 900a is hung on the horizontal part 800a and used. That is, when there is a pot 100a where seedlings are not grown, the pipe 600 is inserted into the floor soil 200 through the hole 100b to a predetermined depth. Then, the soil below the insertion slot 600a enters the pipe 600. When the pipe 600 is pulled out from the pot 100a, the cylindrical soil in the pipe 600 is torn off at the lower end and pulled up from the pot 100a together with the pipe 600. For the highly viscous floor soil 200, if the pipe 600 is inserted into the pot 100a and then the pipe 600 is slightly tilted back and forth and left and right, or if the pipe 600 is turned a little, the cylindrical soil in the pipe 600 is removed. The lower end is cut. Subsequently, the pipe 600 is inserted into the next pot 100a where seedlings are not grown. Then, the above-mentioned cylindrical soil held by the pipe 600 is pushed up by the next soil and discharged from the discharge port 600b to the outside of the pipe 600. Thus, the hole 200b can be continuously formed in the floor soil 200 only by pushing the pipe 600 into the floor soil 200 from the hole 100b. And since the soil is removed in the cylindrical shape and the hole 200b is not compacted as in the prior art, the bottom is soft and the seedlings to be replanted are well established. The soil clogged in the pipe 600 or the soil left in the pipe 600 at the end of the operation is pushed down at the lower end of the push rod 900 when the pin 900a is moved from the top to the bottom in the vertical portion 800b. It is extruded from the insertion port 600a.
本発明は、著しく労力が軽減されるばかりではなく、土壌に穴を開ける際に開口部及び筒状体内部に土壌による詰りがなく、かつ、苗の活着が良好な一芽苗補植用穴あけ器を提供するものである。 The present invention not only remarkably reduces labor, but also makes a hole for replanting a single seedling that has no clogging due to the soil inside the opening and the cylindrical body when the hole is made in the soil, and has good seedling survival. A container is provided.
上記特許文献４の補植用作孔具（図１３）は、人力で実施することができ、また、比較的安価でもあるばかりではなく、従来の補植棒のように土壌を突き固めるものではないことから、苗の活着も比較的良好であると思われていた。しかし、該補植用作孔具では、Ｔ字型に固定されたハンドル７００を腕力、更には、上から体重をかけて、パイプ６００の下端に開放されている挿入口６００ａを土壌（床土２００）中に押し込むものである。従って、欠株数が多かったり、土壌が比較的固かったりすると、繰り返し作業の過程で、やはり、相当の労力を要する作業となった。また、該補植用作孔具では、常に、パイプ６００の下端部分に、穴を開けた際に取り除かれた一定量の土壌が押し込められた状態になっている。従って、その重量も加算され、作業を何回も繰り返すと、更なる労力を課されることになった。加えて、雨上がり時等、土壌が水分を多量に含んでいたりすると、相当な労力となることもあった。加えて、穴あけ作業を繰り返すと、パイプ６００の下端部分に押し込められている土が、次の穴あけ作業により、都合よく上方に押し上げられて、側面の排出口６００ｂから排出されなくなる。即ち、パイプ６００の下端部分に押し込められている土は、繰り返し作業により少しずつ押し固められて密度を増していく。それに伴って、開けた穴もその底部が少しずつ押し固められるようになり、苗の活着が良好ではなくなることも多々あった。また、このパイプ６００の下端部分に押し固められた土壌を押出棒９００で除去するにも労力と時間を要し、一方、土壌がパイプ６００内で余り押し固められていないうちに、押出棒９００でその土をいちいち除去していたのでは、それこそ多大な労力を要してしまう。加えて、押出棒９００の重量も繰り返し作業においてはかなりの負担となり、また、押出棒９００がパイプ６００の内部で多少なりとも左右に振れることも相当の負担となった。そこで、本発明者らは、かかる従来の補植用作孔具における問題点を解決すべく、種々の検討を重ねた。 The hole-making tool for supplemental planting of the above-mentioned patent document 4 (FIG. 13) can be implemented by human power and is not only relatively inexpensive, but it does not squeeze the soil like a conventional planting rod. Because of the lack of seedlings, it was thought that the seedlings were relatively good. However, in the hole-planting tool for supplemental planting, the handle 700 fixed in a T-shape is applied with arm strength, and further weight is applied from above, and the insertion port 600a opened to the lower end of the pipe 600 is made into soil (floor soil). 200). Therefore, if the number of strains was large or the soil was relatively hard, it was an operation that required considerable labor in the process of repeated operations. In addition, in the hole-planting tool for supplemental planting, a certain amount of soil removed when a hole is made is always pushed into the lower end portion of the pipe 600. Therefore, when the weight is added and the operation is repeated many times, further labor is imposed. In addition, if the soil contains a large amount of water, such as after rain, it may be a considerable effort. In addition, when the drilling operation is repeated, the soil pushed into the lower end portion of the pipe 600 is conveniently pushed upward by the next drilling operation and is not discharged from the side discharge port 600b. That is, the soil pushed into the lower end portion of the pipe 600 is gradually pushed up by the repetitive work to increase the density. Along with this, the bottoms of the holes that were drilled were gradually compressed and the seedlings were often not well established. Further, it takes labor and time to remove the soil pressed by the lower end portion of the pipe 600 with the extrusion rod 900, while the extrusion rod 900 is not yet compressed in the pipe 600. If you remove the soil one by one, it will take a lot of effort. In addition, the weight of the push rod 900 is a considerable burden in the repetitive work, and the push rod 900 is slightly swung left and right inside the pipe 600. Then, the present inventors repeated various examinations in order to solve the problem in such a conventional supplementary hole making tool.
その結果、本発明者らは、図１４に示したような、長さ方向の一端に、土壌入口として作用する開口部（１０２）を有し、かつ、側面に、土壌出口として作用する開口部（１０３）を有する筒状体（１０１）を備え、かつ、上記筒状体（１０１）の長さ方向の他端に、該長さ方向に対して略垂直な方向に、踏み板として作用する平板（１０４）を備え、かつ、上記筒状体（１０１）の長さ方向に対して垂直な筒状体断面の中心から離れた位置の該平板（１０４）上に、上記筒状体（１０１）とは反対方向に、該平板（１０４）に対して略垂直に伸びる棒状体（１０５）を備え、該棒状体（１０５）は、その他端に該棒状体（１０５）に略垂直な方向に他の棒状体（１０６）を備え、これら２つの棒状体が全体として略Ｔ字形をなす、一芽苗補植用穴あけ器であって、上記の筒状体側面に備えられた開口部（１０３）の形状が、該筒状体（１０１）の長さ方向に沿って略平行な両端辺を有する略四角形である一芽苗補植用穴あけ器を考え出した。該一芽苗補植用穴あけ器は、作業者が、筒状体の長さ方向の一端に存在する開口部（１０２）を、圃場の所定の位置に設置して、両手又は片手でＴ字形の棒状体を支えつつ、踏み板として作用する平板（１０４）上に片足を載せて押圧して、圃場に筒状体（１０１）を挿入し、次いで、Ｔ字形の棒状体に引き抜き力をかけて、圃場に挿入された筒状体（１０１）を引き抜いて、一芽苗補植用の穴を圃場に開けるものである。該操作において筒状体（１０１）内に取り込まれた土壌は、筒状体（１０１）を引き抜けば、筒状体（１０１）と共に取り出され、そして、場合によっては、例えば、該筒状体（１０１）を足で軽く蹴るなどして軽く外力をかけるなどして、筒状体の側面に設けられている開口部（１０３）から、筒状体（１０１）の外部へと土壌が取り出されるものである。該一芽苗補植用穴あけ器によれば、上記の従来技術のものと比較して、著しく労力が軽減されるものであった。しかし、圃場の土壌の性質、例えば、粘性や水分含有量等によっては、筒状体（１０１）の上部に土壌が押圧されて少しずつ残存し、時には、筒状体（１０１）内部に土壌が詰まってしまうこともあった。そこで、本発明者らは、更なる検討を重ねた結果、下記所定の構成を有する一芽苗補植用穴あけ器によれば、上記問題を解決し得ることを見出し、本発明を完成するに至ったのである。 As a result, the present inventors have an opening (102) that acts as a soil inlet at one end in the length direction as shown in FIG. 14, and an opening that acts as a soil outlet on the side surface. A flat plate comprising a cylindrical body (101) having (103) and acting as a stepping plate at the other end in the longitudinal direction of the cylindrical body (101) in a direction substantially perpendicular to the longitudinal direction (104) and on the flat plate (104) at a position away from the center of the cross section of the cylindrical body perpendicular to the longitudinal direction of the cylindrical body (101), the cylindrical body (101) Is provided with a rod-like body (105) extending substantially perpendicular to the flat plate (104), and the rod-like body (105) is provided at the other end in a direction substantially perpendicular to the rod-like body (105). The rod-shaped body (106), and these two rod-shaped bodies as a whole form a substantially T-shape. A hole punch for use, wherein the shape of the opening (103) provided on the side surface of the cylindrical body is a substantially quadrangle having both ends substantially parallel to the length direction of the cylindrical body (101). I have devised a drilling device for transplanting a single seedling. In this single-plant seedling replanting hole drill, an operator installs an opening (102) existing at one end in the longitudinal direction of a cylindrical body at a predetermined position in a field and is T-shaped with both hands or one hand. While supporting the rod-shaped body, put one foot on the flat plate (104) acting as a stepping plate and press it to insert the tubular body (101) into the field, and then apply a pulling force to the T-shaped rod-shaped body The cylindrical body (101) inserted in the field is pulled out, and a hole for single seedling supplemental planting is opened in the field. The soil taken into the tubular body (101) in the operation is taken out together with the tubular body (101) when pulled out of the tubular body (101), and in some cases, for example, the tubular body The soil is taken out of the cylindrical body (101) from the opening (103) provided on the side surface of the cylindrical body, for example, by gently kicking (101) with a foot and applying a light external force. Is. According to the one-plant seedling replanting hole puncher, the labor is remarkably reduced as compared with the above-mentioned prior art. However, depending on the properties of the soil in the field, such as viscosity and moisture content, the soil is pressed and remains little by little at the top of the tubular body (101), and sometimes the soil is inside the tubular body (101). Sometimes it got stuck. Thus, as a result of further investigations, the present inventors have found that the above-described problem can be solved by the single seedling supplemental hole drill having the following predetermined configuration, and to complete the present invention. It has come.
即ち、本発明は、

上記本発明の第一の態様の一芽苗補植用穴あけ器によれば、上記問題を効果的に解決し得る。その一方、圃場が粘土質の場合には、筒状体と共に取り出した土壌を筒状体から取り出す際に、例えば、筒状体を足で何回か蹴らなければならないようなこともある。このようにすれば、土壌を筒状体から完全に取り出すことが可能ではあるが、僅かではあるがより多くの労力を必要とする。そこで、本発明者らは、圃場が粘土質の場合により効果的に一芽苗補植用の穴を開けるためには、如何にすればよいかを更に検討した。圃場が粘土質の場合に、上記第一の態様の一芽苗補植用穴あけ器で筒状体内に土壌を取り込むと、取り込んだ土壌が多少の外力では壊れ難いことがあり、従って、土壌を、筒状体から側面の開口部を通して良好に取り出すことができないことがあることに気が付いた。その一方、取り込んだ土壌が壊れ難いということは、土壌がその形状を保持する性質が強いということに思い当たった。そこで、本発明者らは、このように粘土質の圃場から土壌を取り出す際には、土壌を取り込む部分をわざわざ筒状体にしなくても、圃場から引き抜いた際に、その土壌は形状を保持し続けるのではないかと考えた。そして、本発明者らは、更に検討を重ねた結果、下記の第二の態様の一芽苗補植用穴あけ器を完成したのである。 According to the single shoot seedling replanting drill of the first aspect of the present invention, the above problem can be effectively solved. On the other hand, when the field is clay, when taking out the soil taken out together with the tubular body from the tubular body, for example, the tubular body may have to be kicked several times with a foot. In this way, it is possible to completely remove the soil from the cylindrical body, but a little more labor is required. Therefore, the present inventors further examined how to make a hole for transplanting a single seedling more effectively when the field is clayey. When the field is clayey, if the soil is taken into the cylindrical body by the single-plant seedling replanter in the first aspect described above, the taken-in soil may not be easily broken by some external force. I noticed that sometimes it could not be taken out from the cylindrical body through the side opening. On the other hand, the fact that the soil that was taken in was hard to break came up with the strong nature that the soil retained its shape. Therefore, the present inventors, when taking out the soil from the clay-like field in this way, the soil retains its shape when it is pulled out from the field without having to make the portion to take in the soil into a cylindrical body. I thought it would continue. As a result of further investigations, the present inventors have completed a single-plant seedling replanting hole puncher according to the second aspect described below.
即ち、本発明は、

It is a substantially quadrilateral having both ends. That is, the shape of the opening (3) when viewed from the front is a substantially square shape. In other words, the opening (3) has two long sides (a 1 , a 2 ) substantially parallel along the length direction of the cylindrical body (1), that is, both end sides, and the cylinder Two short sides (b 1 , b 2 ) are provided along the circumferential direction of the body (1), and the shape when viewed from the front is a rectangle. Of course, each side of the opening (3) is included in a part of the surface of the cylindrical body because the opening is made by making a hole in the side surface of the cylindrical body (1). The opening (3) is provided from the vicinity of the end (7) on the opening (2) side provided at one end of the cylindrical body (1) toward the other end (flat plate) of the cylindrical body (1). It has been. The length of both ends (a 1 , a 2 ) along the length direction of the cylindrical body (1) of the opening (3) is determined by the opening provided at one end of the cylindrical body (1) ( 2) It is preferably 145 to 205 mm, more preferably 155 to 195 mm, and further preferably 165 to 185 mm from the vicinity of the end (7) on the side.

To the other end (flat plate) of the cylindrical body (1), preferably 5 to 20 mm away, more preferably 10 to 20 mm away, more preferably 13 to 17 mm away. Say. The dimensions are from the end (7) on the opening (2) side provided at one end of the cylindrical body (1) to the short side (b 1 ) on the opening (2) side of the opening (3) ( The shortest distance to the bottom edge. The dimension of the opening (3) provided on the side surface of the cylindrical body (1) along the length direction of the cylindrical body (1), that is, the length of both side edges (a 1 , a 2 ), and The distance from the end (7) of the cylindrical body (1) on the opening (2) side to the lower end of the opening (3) depends on the length of the cylindrical body (1) and the like. Determined. If the distance from the end (7) on the opening (2) side to the lower end (b 1 ) of the opening (3) is longer than the above upper limit, it is repeated by the single seedling planting hole drill (A) It is not preferable to make a hole in the field because the excavated soil may be clogged in the cylindrical body portion between the opening (2) and the lower end of the opening (3) provided on the side surface. On the other hand, if the distance is too short, the end (7) on the opening (2) side of the cylindrical body (1) may be deformed or damaged during the operation.
また、該筒状体（１）の側面に備えられている開口部（３）の、筒状体（１）の内周により形成される、筒状体（１）の長さ方向に沿う両端辺、好ましくは、筒状体（１）の長さ方向に沿う２つの長辺（ａ１，ａ２）を含む平面（９）は、該筒状体（１）の長さ方向に対して垂直な筒状体断面の略中心を通る。より好ましくは、筒状体断面の中心（８）を通る。ここで、筒状体断面の略中心とは、該中心から該断面の直径（内径）の１０％以内の範囲を言う。例えば、該断面が略円形であり、その直径が５０ｍｍであるとき、該円形の中心から半径５ｍｍの範囲を言う。該平面（９）が上記範囲を超えて離れることにより、筒状体（１）における開口部（３）の占める部分が小さくなると、掘り出した土壌を筒状体（１）の外部へと排出し難くなる故に、筒状体（１）部分に、掘り出した土壌が詰まることがあるため好ましくない。一方、筒状体（１）における開口部（３）の占める部分が大きくなると、圃場から土壌を効果的に掘り出すことができなくなることがある。図３のＩ−Ｉ断面図に示すように、該実施態様の筒状体（１）においては、開口部（３）の、筒状体（１）の内周により形成される、筒状体（１）の長さ方向に沿う両端辺、即ち、筒状体（１）の長さ方向に沿う２つの長辺（ａ１，ａ２）を含む平面（９）は、筒状体（１）の長さ方向に対して垂直な筒状体断面の中心（８）を通る。 Moreover, the both ends along the length direction of a cylindrical body (1) formed by the inner periphery of the cylindrical body (1) of the opening part (3) with which the side surface of this cylindrical body (1) was equipped.

Here, the approximate center of the cross section of the cylindrical body refers to a range within 10% of the diameter (inner diameter) of the cross section from the center. For example, when the cross section is substantially circular and the diameter is 50 mm, the radius is 5 mm from the center of the circle. When the plane (9) moves beyond the above range and the portion occupied by the opening (3) in the cylindrical body (1) becomes small, the excavated soil is discharged to the outside of the cylindrical body (1). Since it becomes difficult, the excavated soil may be clogged in the cylindrical body (1), which is not preferable. On the other hand, when the portion occupied by the opening (3) in the cylindrical body (1) becomes large, it may not be possible to effectively dig out the soil from the field. As shown in the II cross-sectional view of FIG. 3, in the cylindrical body (1) of this embodiment, the cylindrical body formed by the inner periphery of the cylindrical body (1) of the opening (3). Both sides along the length direction of (1), that is, the plane (9) including the two long sides (a 1 , a 2 ) along the length direction of the cylindrical body (1) are the cylindrical body (1 ) Passes through the center (8) of the cross section of the cylindrical body perpendicular to the longitudinal direction.

The length (total length) of the annular body (21) is preferably 5 to 20 mm, more preferably 10 to 20 mm, and still more preferably 13 to 17 mm. When the dimension is longer than the above upper limit, it is not preferable to repeatedly drill holes in the field with the single seedling planting hole drill (B) because the excavated soil may be clogged in the annular body (21). . On the other hand, if the dimension is too short, the end (27) on the opening (22) side of the annular body (21) may be deformed or damaged during the operation. The openings (22, 23) provided at both ends in the longitudinal direction of the annular body (21) are formed by the inner periphery (30) of the annular body (21), and the longitudinal direction of the annular body (21). It is composed of an annular body cross section in a direction substantially perpendicular to the shape, and the shape is preferably substantially circular. Here, the diameter of the circular body, that is, the diameter (inner diameter) of the cross-section of the annular body in the direction substantially perpendicular to the length direction of the annular body (21) formed by the inner periphery (30) of the annular body (21). ) Is determined depending on the outer diameter of the pot in which the single seedling is planted, and is preferably 30 to 70 mm, more preferably 40 to 60 mm. The opening (22) is a portion where a hole is made when a single seedling is planted in the field by the single seedling supplemental hole drilling device (B), and the inside of the annular body (21) is formed from the opening (22). The soil of the field is taken in. Therefore, the difference between the outer diameter and the inner diameter of the annular body (21), that is, the thickness of the annular body (21) is not particularly limited as long as it is suitable for being able to make a hole in the field, but preferably It is 2-8 mm, More preferably, it is 3-6 mm, More preferably, it is 3-5 mm. If it is less than the lower limit, the end (27) on the opening (22) side of the annular body (21) may be deformed or damaged during the operation. Moreover, it is preferable that the edge part (27) by the side of the opening part (22) of an annular body (21) is an acute angle toward the outer side of an annular body (21) so that it may be easy to make a hole in a farm field. .
本発明の第二の態様の一芽苗補植用穴あけ器（Ｂ）は、上記環状体（２１）の外周面、内周面又は端面に端部近傍で固定され、かつ、該環状体（２１）の長さ方向に沿って伸びる略平行な複数本の棒状体、好ましくは２〜３本の棒状体、ここでは、より好ましい態様である２本の棒状体（３２，３３）を備える。該２本の棒状体（３２，３３）は、環状体（２１）へ固定するための作業の簡便さ、一芽苗補植用穴あけ器（Ｂ）による穴開け作業のし易さ等の観点から、環状体（２１）の外周面に固定されることが好ましい。また、環状体（２１）に固定された側の棒状体（３２，３３）の先端部分は、その外側から内側に向かって（環状体に接していない側から接している側に向かって）傾斜を有していることが好ましい。上記の略平行な２本の棒状体（３２，３３）の長さ方向の寸法は、上記環状体（２１）の、土壌出口として作用する開口部（２３）側の端部近傍から、好ましくは１６０〜２３０ｍｍ、より好ましくは１７０〜２２０ｍｍ、更に好ましくは１８０〜２１０ｍｍである。上記下限未満では、圃場に開けた穴が十分な深さにならず一芽苗を補植するために十分ではないことがある。一方、上記上限を超えては、逆に圃場に開けた穴が深過ぎて一芽苗を補植するために適当とは言えないことがあるばかりではなく、不要な土壌の除去作業により不必要な労力を課されることがある。また、上記環状体から伸びる略平行な２本の棒状体の長さ方向に対して垂直な棒状体断面の形状及び寸法は、一芽苗補植用穴あけ器（Ｂ）による穴開け作業に支障のない形状及び寸法であれば特に制限はない。好ましくは略円形であり、該断面形状が円形であるとき、該円形の直径は、好ましくは５〜１５ｍｍ、より好ましくは６〜１０ｍｍである。 The single-plant seedling replanting drill (B) of the second aspect of the present invention is fixed to the outer peripheral surface, inner peripheral surface or end surface of the annular body (21) in the vicinity of the end, and the annular body ( 21) A plurality of substantially parallel rod-like bodies extending along the length direction, preferably 2 to 3 rod-like bodies, here, two rod-like bodies (32, 33) which are more preferred embodiments. The two rod-shaped bodies (32, 33) are easy to work for fixing to the annular body (21), and easy to drill with a single seedling transplanting drill (B). Therefore, it is preferable to be fixed to the outer peripheral surface of the annular body (21). The tip of the rod-like body (32, 33) fixed to the annular body (21) is inclined from the outside to the inside (from the side not in contact with the annular body to the side in contact). It is preferable to have. The dimension in the length direction of the two substantially parallel rod-like bodies (32, 33) is preferably from the vicinity of the end of the annular body (21) on the side of the opening (23) that acts as a soil outlet. It is 160-230 mm, More preferably, it is 170-220 mm, More preferably, it is 180-210 mm. If it is less than the said minimum, the hole drilled in the field may not be enough depth, and it may not be enough to supplement a single seedling. On the other hand, if the above upper limit is exceeded, the hole drilled in the field is too deep and may not be suitable for replanting a single seedling. May be burdensome. In addition, the shape and size of the cross-section of the rod-shaped body perpendicular to the length direction of the two substantially parallel rod-shaped bodies extending from the ring-shaped body obstructs the drilling operation by the single-plant seedling transplanting drill (B). There is no particular limitation as long as the shape and dimensions are not. Preferably, it is substantially circular, and when the cross-sectional shape is circular, the diameter of the circular shape is preferably 5 to 15 mm, more preferably 6 to 10 mm.
また、上記環状体から伸びる略平行な２本の棒状体（３２，３３）の長さ方向に対して垂直な棒状体断面の中心から成る２つの直線、即ち、略平行な２本の棒状体（３２，３３）の長さ方向の中心線（ａ３，ａ４）を含む平面（２９）は、環状体（２１）の長さ方向に対して垂直な環状体断面の略中心を通る。ここで、環状体断面の略中心とは、該中心から該断面の直径の１０％以内の範囲を言う。例えば、該断面が略円形であり、その直径が５０ｍｍであるとき、該円形の中心から半径５ｍｍの範囲を言う。該平面が上記範囲を超えて離れると、一芽苗補植用穴あけ器（Ｂ）による穴開け作業において、略平行な２本の棒状体（３２，３３）にかかる力に不均衡が生ずることがあり、作業に支障をきたすことがあるばかりではなく、略平行な２本の棒状体（３２，３３）が変形するおそれがある。図６のＩ−Ｉ断面図に示すように、該実施態様の略平行な２本の棒状体（３２，３３）においては、２本の棒状体の長さ方向に対して垂直な棒状体断面の中心から成る２つの直線（ａ３，ａ４）を含む平面（２９）は、環状体（２１）の長さ方向に対して垂直な環状体断面の中心（２８）を通る。ここでは、上記環状体から伸びる略平行な複数本の棒状体の数が２本である場合を述べたが、該棒状体の数は、好ましくは２〜３本であり、より好ましくは２本である。従って、上記環状体から伸びる略平行な２本の棒状体（３２，３３）のほかに、これらに平行な他の棒状体を好ましくは１〜２本有することもできる。このように他の棒状体を有することにより、一芽苗補植用穴あけ器（Ｂ）を補強することができる。 Further, two straight lines composed of the centers of the cross-sections of the rod-shaped bodies perpendicular to the length direction of the two substantially parallel rod-shaped bodies (32, 33) extending from the annular body, that is, two rod-shaped bodies substantially parallel to each other. The plane (29) including the center line (a 3 , a 4 ) in the length direction of (32, 33) passes through the approximate center of the section of the annular body perpendicular to the length direction of the annular body (21). Here, the approximate center of the cross section of the annular body refers to a range within 10% of the diameter of the cross section from the center. For example, when the cross section is substantially circular and the diameter is 50 mm, the radius is 5 mm from the center of the circle. When the plane moves beyond the above range, an imbalance occurs in the force applied to the two substantially parallel rod-shaped bodies (32, 33) in the drilling operation by the single-plant seedling transplanting drill (B). This may not only hinder the work but also may cause deformation of the two substantially parallel rods (32, 33). As shown in the II cross-sectional view of FIG. 6, in the substantially parallel two rod-shaped bodies (32, 33) of the embodiment, the section of the rod-shaped body perpendicular to the length direction of the two rod-shaped bodies. A plane (29) including two straight lines (a 3 , a 4 ) consisting of the center of the ring passes through the center (28) of the annular body cross section perpendicular to the longitudinal direction of the annular body (21). Although the case where the number of the substantially parallel rod-shaped bodies extending from the annular body is two is described here, the number of the rod-shaped bodies is preferably 2 to 3, more preferably two. It is. Therefore, in addition to the substantially parallel two rod-shaped bodies (32, 33) extending from the annular body, it is also possible to have one or two other rod-shaped bodies parallel to these. Thus, by having another rod-shaped body, the shoot seedling replanting hole punch (B) can be reinforced.

Example 1
What was shown in FIG. 11 was used as a drilling machine (A) for one seedling seedling replanting. All the parts constituting the single seedling planting hole drill (A) are made of stainless steel. The shape of the cross section perpendicular to the length direction of the cylindrical body (1) is circular, the outer diameter of the circle is 60.5 mm, and the inner diameter (diameter of the opening (2)) is 53.5 mm. The dimension in the length direction is 200 mm. The opening (3) provided on the side surface of the cylindrical body (1) extends along the length direction of the cylindrical body (1) from a position 15 mm away from the end (7) of the cylindrical body (1). (In the direction of the flat plate (4)). The shape of the opening (3) viewed from the front is rectangular, the dimension (long side) along the length direction of the cylindrical body (1) is 175 mm, and the length direction of the cylindrical body (1) The dimension (short side) in the direction perpendicular to is the same as the inner diameter (diameter of the opening (2)) of the cylindrical body (1), and is 53.5 mm. Further, from the inside of the side surface of the tubular body (1) at a position where the plate-shaped body (11) is 50 mm away from the portion in contact with the flat plate (4) of the tubular body (1) toward the opening (2). It protrudes through the opening (3) in the direction of the flat plate (4) at an inclination angle (θ 1 ) of 30 degrees with respect to a plane perpendicular to the length direction of the cylindrical body (1). The plate-like body (11) has a substantially semicircular shape in which the shape of the cross section perpendicular to the length direction has a convex portion in the direction of the flat plate (4). The dimension (outer diameter) in the width direction of the plate-like body (11), that is, the diameter of the semicircle (outer diameter) is the same as the inner diameter of the cylindrical body (1), and is 53.5 mm. The plate-like body (11) is fixed to the inside of the side surface of the tubular body (1) by welding at the entire end portion existing inside the tubular body (1). The rod-like bodies (5) and (6) are pipes having a circular cross section with an outer diameter of 22 mm. Using the single shoot seedling replanting hole puncher (A), 50 holes were sequentially drilled in approximately one row in the field. The excavated soil was not clogged inside the cylindrical body (1), and the soil taken into the cylindrical body (1) from the opening (2) was discharged well from the opening (3). . In addition, the work of making 50 holes was completed in about 10 minutes without having to take a break in the middle.
（比較例１）
図１２に示した従来の補植棒を使用して、実施例１と同様に圃場に順次ほぼ一列に５０個の穴を開けた。該補植棒によれば、圃場の土壌を押し込んで穴を形成する故に、作業に相当の労力を要した。５０個の穴を開ける作業を完了するためには、休み休み作業を継続する必要があり、作業完了までおよそ１５分間を要した。また、形成された穴は逆円錐状であり、ポットから取り出した一芽苗を植え付けるためには適しておらず、更なる作業が必要となった。また、形成された穴は土を押し固めたものである故に、苗の活着が十分になされるか否かの問題も残った。
(Comparative Example 1)
Using the conventional planting rod shown in FIG. 12, 50 holes were sequentially drilled in a line in the field in the same manner as in Example 1. According to the supplementary planting stick, the soil in the field was pushed in to form a hole, so that considerable work was required for the work. In order to complete the work of opening 50 holes, it was necessary to continue the resting work, and it took approximately 15 minutes to complete the work. In addition, the formed hole has an inverted conical shape and is not suitable for planting a single seedling taken out from the pot, and further work is required. In addition, since the formed hole is formed by pressing the soil, there remains a problem as to whether or not the seedlings are sufficiently established.
（比較例２）
図１３に示した特許文献４記載の補植用作孔具を作製して、実施例１と同様に圃場に順次ほぼ一列に５０個の穴を開けた。作業開始からしばらくは良好に穴を開けることができたものの、約２０個目の穴を開けるころから、パイプ６００内部の土壌をパイプ側面の排出口６００ｂから、良好にパイプ６００の外部へと排出することができなくなった。パイプ６００の内部を見ると土壌がその壁面を中心に詰りはじめていた。そこで、押出棒９００を使用して内部の土壌を外部へ放出せしめた。その後、穴あけ作業を継続したところ、約３５個目の穴を開けるころから、再度、パイプ６００の内部が土壌で詰り始めたので、再度、押出棒９００を使用して内部の土壌を外部へと放出せしめた。更に作業を継続したところ、約４５個目の穴を開けるころから、再度、パイプ６００の内部が土壌で詰り始めたので、再度、押出棒９００を使用して内部の土壌を外部へ放出せしめた。結局、合計３回、押出棒９００を使用してパイプ６００の内部の土壌を外部へ放出する作業を行った。従って、作業完了までおよそ２０分間を要した。
(Comparative Example 2)
The hole making tool for supplemental planting described in Patent Document 4 shown in FIG. 13 was produced, and 50 holes were sequentially formed in a row in the field in the same manner as in Example 1. Although we were able to make a good hole for a while after the start of work, the soil inside the pipe 600 was well discharged from the outlet 600b on the side of the pipe to the outside of the pipe 600 after the 20th hole was made. I can no longer do it. Looking at the inside of the pipe 600, the soil began to clog around its wall surface. Accordingly, the internal soil was discharged to the outside using the extrusion rod 900. After that, when the drilling operation was continued, since the inside of the pipe 600 began to be clogged again with the soil from the time when the about 35th hole was drilled, the internal soil was again released to the outside using the extrusion rod 900. It was released. When the operation was further continued, the pipe 600 began to clog again with the soil from the time when the 45th hole was opened. The extruded rod 900 was used again to discharge the internal soil to the outside. . Eventually, the work which discharge | releases the soil inside the pipe 600 outside using the extrusion rod 900 was performed a total of 3 times. Therefore, it took about 20 minutes to complete the work.
（比較例３）
図１４に示した一芽苗補植用穴あけ器を使用して、実施例１と同様に圃場に順次ほぼ一列に５０個の穴を開けた。該一芽苗補植用穴あけ器は、板状体（１１）が備えられていないことを除いて、その寸法、形状、材質は実施例１で使用した一芽苗補植用穴あけ器（Ａ）と同じである。開口部（１０２）から筒状体（１０１）の内部に取り込まれた土壌は開口部（１０３）から良好に排出された。また、実施例１と同様に、５０個の穴を開ける作業は途中に休憩等を取る必要はなかったが、作業時間はおよそ１２分間であり、実施例１に比較して多少長くなった。作業終了後、筒状体（１０１）の内部を調べたところ、その上部から２０〜３０ｍｍ程度土壌が詰まっていた。更に継続して穴開けを実施すれば、筒状体（１０１）の内部に更に多くの土壌が詰まることが予測され、作業時間及び労力をより多く要することが明らかであった。従って、ある程度の穴開け作業をした後に筒状体（１０１）の内部に詰まった土壌を掻きだす等の作業が必要であることが分かった。
(Comparative Example 3)
Using the single shoot seedling replanting drill shown in FIG. 14, 50 holes were sequentially formed in approximately one row in the field in the same manner as in Example 1. The single shoot seedling replanting hole punch is a single shoot seedling replanting hole punch (A) used in Example 1, except that the plate-like body (11) is not provided. ). The soil taken into the inside of the cylindrical body (101) from the opening (102) was discharged well from the opening (103). In addition, as in Example 1, it was not necessary to take a break during the operation of making 50 holes, but the operation time was about 12 minutes, which was slightly longer than that in Example 1. When the inside of the cylindrical body (101) was examined after the work was completed, the soil was clogged by about 20 to 30 mm from the upper part. If drilling was continued further, it was predicted that more soil would be clogged inside the tubular body (101), and it was clear that more work time and labor were required. Therefore, it was found that after performing a certain amount of drilling work, work such as scraping out the clogged soil inside the cylindrical body (101) was necessary.
（実施例２）
一芽苗補植用穴あけ器（Ｂ）として、図１５に示すものを使用した。該一芽苗補植用穴あけ器（Ｂ）を構成する全ての部分はステンレス鋼製である。環状体（２１）の長さ方向に垂直な断面の形状は円形であり、該円の外径は６０．５ｍｍであり、内径（開口部（２２）及び（２３）の直径）は５３．５ｍｍであり、また、長さ方向の寸法は１５ｍｍである。環状体（２１）の外周面には、該環状体（２１）の長さ方向に垂直な断面の中心を通る平面上の対抗する位置に固定された、環状体（２１）の長さ方向に沿って伸びる平行な２本の棒状体（３２，３３）が備えられている。２本の棒状体（３２，３３）の長さは、いずれも１９５ｍｍであり、環状体（２１）の開口部（２３）側の端部から１８５ｍｍであり、環状体（２１）の開口部（２２）側の端部から棒状体（３２，３３）の末端、即ち、平板（２４）までの寸法は２００ｍｍである。また、２本の棒状体（３２，３３）は、外径８ｍｍの丸棒である。該一芽苗補植用穴あけ器（Ｂ）を使用して、圃場に順次ほぼ一列に５０個の穴を開けた。但し、該圃場は、実施例１及び比較例１〜３において使用した圃場とは異なり粘土質であり相当固いものであった。環状体（２１）の内部から２本の棒状体（３２，３３）との間に土壌を良好に取り込むことができて、効果的に穴開け作業を継続することができた。また、掘り出した土壌が詰まることはなく、環状体（２１）の内部から２本の棒状体（３２，３３）との間に取り込まれた土壌は、２本の棒状体（３２，３３）の間隙から良好に排出された。また、５０個の穴を開ける作業は途中に休憩等を取る必要もなくおよそ１０分間で完了した。
(Example 2)
What was shown in FIG. 15 was used as a drilling machine (B) for single seedling replanting. All parts constituting the single seedling planting hole drill (B) are made of stainless steel. The shape of the cross section perpendicular to the longitudinal direction of the annular body (21) is circular, the outer diameter of the circle is 60.5 mm, and the inner diameter (the diameter of the openings (22) and (23)) is 53.5 mm. In addition, the dimension in the length direction is 15 mm. The outer circumferential surface of the annular body (21) is fixed in the longitudinal direction of the annular body (21), which is fixed at an opposing position on a plane passing through the center of the cross section perpendicular to the longitudinal direction of the annular body (21). Two parallel rods (32, 33) extending along the line are provided. The lengths of the two rod-shaped bodies (32, 33) are both 195 mm, 185 mm from the end on the opening (23) side of the annular body (21), and the opening ( The dimension from the end on the 22) side to the end of the rod-like body (32, 33), that is, the flat plate (24) is 200 mm. The two rod-like bodies (32, 33) are round bars having an outer diameter of 8 mm. Using the single shoot seedling replanting drill (B), 50 holes were sequentially drilled in a row in the field. However, unlike the field used in Example 1 and Comparative Examples 1 to 3, the field was clayey and quite hard. The soil could be satisfactorily taken in between the two rod-shaped bodies (32, 33) from the inside of the annular body (21), and the drilling operation could be continued effectively. Further, the excavated soil is not clogged, and the soil taken in between the two rod-shaped bodies (32, 33) from the inside of the annular body (21) is the two rod-shaped bodies (32, 33). Drained well from the gap. In addition, the work of making 50 holes was completed in about 10 minutes without having to take a break in the middle.
本発明の一芽苗補植用穴あけ器によれば、土壌の穴あけに要する労力が著しく軽減されるばかりではなく、土壌に穴を開ける際に、該穴あけ器の開口部の土壌による詰りがなく、かつ、開けた穴に苗を植え付けた際、その活着が至って良好となることから、今後、一芽苗、とりわけ、サトウキビの一芽苗の補植用として、大いに利用されることが期待される。 According to the single shoot seedling replanting hole drill of the present invention, not only the labor required for soil drilling is remarkably reduced, but also when the hole is drilled in the soil, the opening of the hole puncher is not clogged by the soil. In addition, when seedlings are planted in open holes, the survival of the seedlings is improved and it is expected that the seedlings will be used for supplementary transplantation of single seedlings, especially sugarcane single seedlings.
