Description

本発明は、例えば水田などの泥地状の農耕地で作物の周囲に生える雑草の発芽や生育を抑制したり、生えた雑草を除草したりする抑草除草装置に関するものである。   The present invention relates to a weed control device that suppresses germination and growth of weeds that grow around crops in a muddy farmland such as paddy fields, and that weeds the grown weeds.

従来、水田等の泥地で使用する除草装置は、例えば走行体の後方に除草体を設け、この走行体の走行により除草体を牽引走行せしめると共に、この除草体によって泥地に生える雑草の除草を行う構成のものが一般的であるが、この除草体の多くは、回転刃によって雑草の生える泥地を雑草諸共ほり起こしてこの泥地中に張られた雑草の根を掻き切って除草する構成である為、例えば田植え後の水田のような稲の苗が植えられた状況では、回転刃を有する除草体によって雑草だけでなく稲の苗までも掘り起こしてしまい、この稲の苗の周囲に生える雑草だけを選択的に除草することができない為に使用することができない。   2. Description of the Related Art Conventionally, weeding devices used in swamps such as paddy fields are provided with, for example, a weeding body at the back of a traveling body, and the weeding body is towed by running of the traveling body, and weeds of weeds that grow on the swamp by this weeding body However, many of these herbicides are composed of a rotating blade that weeds the swamp where weeds grow and weed the roots of the weed stretched in the swamp. Therefore, for example, in the situation where rice seedlings such as paddy fields after planting are planted, not only weeds but also rice seedlings are dug up by the weeding body having a rotating blade, and it grows around this rice seedlings Because weeds cannot be selectively weeded, they cannot be used.

よって、上述したような稲の苗などの作物が植えられているところで作物の周囲に生える雑草の除草作業を行う際は、生産者が鎌などの草取り具を使用して手で雑草を刈り取るか、或いは除草剤を散布するかのいずれかしかなかった。   Therefore, when weeding the weeds that grow around crops such as rice seedlings as described above, the producers must use their weeding tools such as sickle to mow the weeds by hand. Or sprayed with herbicides.

しかしながら、前者の人手によって行う除草作業は多大な労力と時間を要する問題があり、また、後者の除草剤による除草作業は、化学薬剤を使用することによる作物の品質低下や、地下水汚染などの環境破壊の問題、更には同じ除草剤の繰り返し使用による除草効果の低減(除草剤に対する耐性が雑草に生ずる)などの懸念があり、いずれの除草作業も問題を抱えていた。   However, the former weeding work has the problem that it takes a lot of labor and time, and the latter weeding work with the herbicide is an environment such as the deterioration of the quality of crops caused by the use of chemical agents and the contamination of groundwater. All herbicidal work had problems, such as the problem of destruction and further reduction of the herbicidal effect due to repeated use of the same herbicide (resistance to the herbicide occurs in weeds).

そこで、本願発明者は、作物の周囲に生える雑草に対して、除草体の牽引走行時にこの除草体の泥面引掻き手段の根切り機能によって、作物の根を切ることなく雑草の根だけを掻き切って除草することができる除草装置として、特許第4851764号を開発している。   Therefore, the present inventor cuts only the roots of the weeds without cutting the roots of the crops without cutting the roots of the weeds that grow around the crops by the root cutting function of the mud surface scratching means of the herbicidal body during the towing of the herbicides. As a weeding device that can be weeded, Japanese Patent No. 4851764 has been developed.

この特許第4851764号は、泥面を走行する走行体に牽引されて牽引走行する除草体をこの走行体に設け、この除草体は複数の引掻き線体により前記泥面を引っ掻く泥面引掻き手段を備え、この泥面引掻き手段の後方側に複数の引掛け線体により前記泥面に生える雑草を引っ掛ける雑草引掛け手段を備えた構成とし、前記泥面引掻き手段は、複数の各引掻き線体の下端を前記泥面に沈み込ませると共にこの沈み込み深さを前記泥面に生える雑草の根に到達し且つ作物の根に到達しない所定深さに設定してこの引掻き線体によりこの泥面の下層の雑草の根を掻き切る根切り機能を有する構成とし、前記雑草引掛け手段は前記複数の各引掛け線体の下端側を前記泥面に当接すると共にこの各引掛け線体の下端側に引掛け突部を設けて、この各引掛け線体の引掛け突部が前記泥面に生える雑草に当接した際にはこの雑草を引掛け突部に引っ掛けて泥面から除去し、且つこの引掛け突部が前記泥面に生える作物に当接した際にはこの作物との当接押圧により前記引掛け線体が撓み前記引掛け突部が作物に対して左右に回避動してこの作物を泥面から除去しないように雑草引掛け手段の各引掛け線体の可撓性を設定した除草装置である。   This patent No. 4856464 is provided with a weeding body that is pulled by a traveling body that travels on a muddy surface, and this weeding body has a muddy surface scratching means that scratches the muddy surface with a plurality of scratching lines. Provided with a weed hooking means for hooking weeds that grow on the mud surface by a plurality of hooking wire bodies on the rear side of the mud surface scratching means, and the mud surface scratching means includes a plurality of scratching wire bodies. The lower end is submerged in the mud surface, and the subsidence depth is set to a predetermined depth that reaches the roots of the weeds that grow on the mud surface and does not reach the roots of the crops. The weed hooking means abuts the lower end side of each of the plurality of hooking wire bodies against the mud surface and pulls the lower end side of each of the hooking wire bodies. Each of these is provided with a hanging protrusion When the hooking protrusion of the hanging wire body comes into contact with the weed growing on the mud surface, the weed is hooked on the hooking protrusion and removed from the mud surface, and the hooking protrusion grows on the mud surface. When the abutment comes into contact with the crop, the hook wire is bent by the contact pressure with the crop, and the weeds prevent the catch protrusion from moving left and right with respect to the crop so that the crop is not removed from the mud surface. It is a weeding device in which the flexibility of each hooking wire body of the hooking means is set.

A weeding and weeding device for weeding , wherein a plurality of scratching bodies 1 for scratching the upper layer of the muddy land are provided on the horizontal body 13 so as to project downward, and at least 4 cm in the lateral direction perpendicular to the traveling direction . Three or more rows of scratching work sections 2 formed in parallel with a space are arranged in the front-rear direction , which is the traveling direction, and the two scratching bodies 1 adjacent to one of the scratching work sections 2 are swamped. The other scratch is applied to the scratching body 1 of the one scratching work unit 2 so that the interval of the movement trajectory moving while scratching is divided into three or more by the scratching body 1 of the other scratching work unit 2. Scratch body 1 of working part 2 is left or right Together arranged by shifting the position in the direction, at equal intervals each interval of movement locus 1.5cm of each said scratching body 1 of one scratch working unit 2, and the other scratch working unit 2 is formed when moving The scratching body 1 is configured as a concavo-convex hanging body that goes in and out in the front-rear direction and is submerged in the swamp at the lower end to scratch the upper layer of the swamp. scratching cutting unit 3 or taken off the roots of the weeds stretched in the upper layer of the swamp is provided, a structure in which the vertical state to the horizontal rod 13, the scratching cutting unit 3, the scratch body 1 of the lower end portion According to the weeding and weeding apparatus, the tip part is submerged to a depth of 5 to 15 mm from the upper layer of the swamp by the subsidence prevention part 4 projecting in the horizontal direction. .

また、前記引掻き体1は、下方に向けてこの引掻き体1の下端に突設した前記引掻き切断部3の基端側に、前記沈み込み防止部4を連設した構成とし、この沈み込み防止部4は、前記引掻き切断部3に対して進行方向に突出状態に設けたことを特徴とする請求項1記載の抑草除草装置に係るものである。 Further, the scratching body 1 has a configuration in which the subsidence prevention part 4 is continuously provided on the base end side of the scratch cutting part 3 projecting downward from the lower end of the scratching body 1, and the subsidence prevention is performed. part 4 is according to Somosomokusa herbicidal device according to claim 1, characterized in that provided in the projecting state in the traveling direction with respect to the scratching cutting unit 3.

The lower end side of the projecting side part facing the sag is used as the subsidence prevention part 4 according to any one of claims 1 and 2 .

本発明は上述のように構成したから、泥地(例えば水田)で栽培している作物を傷めずに、この作物の周囲に生息する雑草の発芽を抑制することができ、更に、既に作物の周囲に生えた雑草だけを選択的に除草することができ、しかも、この抑草作業と除草作業とを同時に行うことができる実用性に優れた画期的な抑草除草装置となる。   Since the present invention is configured as described above, it is possible to suppress the germination of weeds inhabiting this crop without damaging the crop cultivated in the swamp (for example, paddy field). Only a weed that grows in the surrounding area can be selectively weeded, and this epoch-making weeding and removal weeding apparatus is excellent in practicality and capable of performing the weeding work and the weeding work at the same time.

即ち、本発明は、引掻き体に設けた引掻き切断部が、沈み込み防止部によって、発芽前の雑草の種が生息したり、発芽し生長した雑草が根を張る泥地の上層のみを引っ掻き、この泥地に栽培している作物が根を張る深い位置まで引っ掻かないので、作物の根を掻き切らずに、泥地の上層を引っ掻きほぐしてこの泥地の上層に生息する雑草の発芽を抑制したり、既に発芽し生長している雑草の根だけを選択的に掻き切って除草したりすることができる実用性に優れた画期的な抑草除草装置となる。   That is, in the present invention, the scratch cutting part provided in the scratching body, by the subsidence prevention part, inhabit the seeds of weeds before germination, or scratches only the upper layer of the swamp where the weeds that have sprouted and grown are stretched. Since the crops cultivated in this swamp do not scratch deeper than the roots of the crop, the upper layers of the swamps are scratched and the weeds that inhabit the upper layers of the swamps are germinated without scratching the roots of the crops. It is an epoch-making innovative herbicidal weeding device that can suppress or selectively scrape only weed roots that have already germinated and grown.

更に、泥地の上層を引っ掻く引掻き切断部を設けた引掻き体を、水平方向に出入りする凹凸形状に形成したので、引掻き体の強度(剛性)が向上し、引掻き切断部が泥地の上層を引っ掻く際に生じる抵抗によって引掻き体の下端側が大きく反らず、よって、引掻き切断部が浮き上がったり角度が寝たりすることなく、略垂下状態で所定の沈み込み深さまで沈み込んで、発芽前の雑草が生息する泥地の上層を確実に引っ掻いて泥地をほぐすことができ、更に、この泥地の上層に張られた雑草の根を確実に掻き切ることができる実用性に優れた画期的な抑草除草装置となる。   Furthermore, since the scratched body provided with the scratch cutting part that scratches the upper layer of the swamp is formed in an uneven shape that goes in and out in the horizontal direction, the strength (rigidity) of the scratched body is improved, and the scratch cutting part is The lower end of the scratched body does not greatly warp due to the resistance generated when scratching, so that the weeds before germination are submerged to a predetermined subsidence depth in a drooping state without the scratch cutting part being lifted or sleeping at an angle. It is a revolutionary that has excellent practicality that can surely scratch the upper layer of the swamp inhabited by the mud and loosen the swamp, and can surely scrape the roots of the weed stretched on the upper layer of the swamp. It becomes a weeding weeding device.

しかも、本発明は、進行方向と直交する左右方向に並設した引掻き体の並設間隔を、泥地に散在する稲わらや除草した雑草が絡みついて目詰まりを起こさない幅広の間隔に設定しても、泥地を引っ掻きながら移動する引掻き体全体で描く移動軌跡の間隔を、左右方向に並設した引掻き体の並設間隔よりも狭い間隔に容易に設定可能な構成であり、これによって、引掻き体が泥地を引っ掻く際、引掻き作業部に稲わらや雑草が絡みついて引掻き作業部が目詰まりを起こすことがなくなり、この引掻き作業部が目詰まりしないことで、移動時に栽培している作物を倒すことなく移動することができるので、作物を傷めることなく良好に抑草、除草作業を行うことができる実用性に優れた画期的な抑草除草装置となる。   Moreover, the present invention sets the interval between the scrapers arranged side by side in the left-right direction perpendicular to the traveling direction to a wide interval that does not cause clogging due to entanglement of rice straw and weeds scattered in the swamp. However, it is a configuration that can easily set the interval of the movement trajectory drawn in the entire scratching body that moves while scratching the muddy ground to an interval narrower than the parallel arrangement interval of the scratching bodies arranged side by side in the left-right direction. When the scratching body scratches the swamp, rice straw and weeds will not get tangled in the scratching work part, and the scratching work part will not be clogged. Therefore, it is an epoch-making weeding and weeding device excellent in practicality that can satisfactorily perform weeding and weeding work without damaging crops.

また、本発明を、水を張った水田で使用した場合は、引掻き体が泥地を引っ掻くことでこの泥面の上層の泥が水中に撹拌されて水面が泥水状に濁るので、発芽前の雑草に対して日光の照射率を低下させ発芽を抑制することができる画期的な抑草除草装置となる。   In addition, when the present invention is used in a paddy field filled with water, the scratching body scratches the muddy ground, so that the mud on the upper surface of the mud surface is stirred in the water and the water surface becomes cloudy in the form of muddy water. It is an epoch-making weeding and weeding device that can reduce germination by reducing the irradiation rate of sunlight against weeds.

また、本発明は、より一層引掻き体の強度が向上し、より確実に泥地を引っ掻きほぐしたり、スムーズに雑草の根を掻き切ったりすることができ、しかも、泥地のより多くの場所を引っ掻きほぐすことができ、これにより、一層多くの雑草の発芽を抑制することができ、更に、より多くの雑草の根を掻き切ることができる実用性に優れた画期的な抑草除草装置となる。 In addition, the present invention further improves the strength of the scratching body, can more reliably scrape the swamp, and smoothly scrape the roots of the weeds , and can scratch more places in the swamp. This makes it possible to suppress germination of a larger number of weeds, and to provide a revolutionary herbicidal weeding device excellent in practicality that can scrape more roots of weeds.

また、請求項2,3記載の発明においては、より簡易な構成で引掻き体に設けた引掻き切断部の沈み込み深さを設定することができ、特に、請求項4記載の発明においては、一層簡易な構成で前記作用効果を発揮することができる画期的な抑草除草装置となる。 Further, in the inventions according to claims 2 and 3 , it is possible to set the sinking depth of the scratch cutting portion provided in the scratch body with a simpler configuration. It is an epoch-making weeding and weeding apparatus that can exert the above-described effects with a simple configuration.

好適と考える本発明の実施形態を、図面に基づいて本発明の作用を示して簡単に説明する。   An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

水田などの泥地上若しくは泥地上に張った水の表面に設置すると、前後方向に並設される複数の引掻き作業部2を形成する複数の引掻き体1の下端に設けた夫々の引掻き切断部3が泥地に接地すると共にこの泥地中に沈み込む。   When installed on mud surface such as paddy fields or on the surface of water stretched on the mud surface, each scratch cutting section 3 provided at the lower end of a plurality of scratch bodies 1 forming a plurality of scratch working sections 2 arranged side by side in the front-rear direction. Touches the swamp and sinks into the swamp.

この際、引掻き切断部3は、沈み込み防止部4によって泥地中に所定の深さまで、具体的には、発芽前の雑草の種が生息する泥地の上層付近で、泥地に生えている雑草の根には到達するがこの雑草の根よりも深い位置に張られているこの泥地に栽培している作物の根には到達しない深さまで沈み込んだ状態となる。   At this time, the scratch cutting unit 3 grows up to a predetermined depth in the swamp by the subsidence prevention unit 4, specifically, near the upper layer of the swamp where weed species before germination live. It reaches the roots of the weeds, but is submerged to a depth that does not reach the roots of the crops that are cultivated in this swamp that is deeper than the roots of the weeds.

この引掻き切断部3が泥地中に所定の深さまで沈み込んだ状態で移動させると、この泥地中に沈み込んだ引掻き切断部3は、泥地の上層を引っ掻きながら移動することとなり、これによって、泥地の上層側が耕されたようにほぐれた状態となり、安定した状態で埋まっている発芽前の雑草の種の環境を不安定にして雑草の発芽を抑制する抑草作業と、既に泥地に生えている雑草の根を掻き切って除草する除草作業が同時に成される。   When the scratch cutting part 3 is moved in a state where it is submerged to a predetermined depth in the swamp, the scratch cutting part 3 submerged in the swamp moves while scratching the upper layer of the swamp. The muddy upper layer is loosened as if it was plowed, and the pre-emergence weed seeds that are buried in a stable state destabilize the environment and suppress the weed germination. Weeding work is done at the same time by weeding roots of weeds growing on the ground.

この際、この泥地を引っ掻く引掻き切断部3は、雑草の根よりも深い位置に根を張る作物の根には到達し得ない深さまでしか沈み込まないので、泥地の上層に根を張る雑草は根を掻き切られるが、この雑草よりも深い位置に根を張る作物は根を掻き切られることはなく、よって、引掻き切断部3は雑草の根だけを選択的に掻き切ることとなる。   At this time, the scratch cutting section 3 for scratching the swamp sinks only to a depth that cannot reach the root of the crop that is deeper than the root of the weed. Therefore, the weed that roots the upper layer of the swamp Although the roots are scraped off, the crops that have roots deeper than the weeds are not scraped off, so that the scratch cutting unit 3 selectively cuts only the roots of the weeds.

また、引掻き体1は、下端に設けた引掻き切断部3が泥地を引っ掻きながら移動する際の抵抗によって、移動時は引掻き切断部3を設けた下端側が進行方向と反対方向に反る力を受ける。   Further, the scratching body 1 has a force that the lower end side provided with the scratch cutting part 3 warps in the direction opposite to the traveling direction due to resistance when the scratch cutting part 3 provided at the lower end moves while scratching the swamp. receive.

この際、例えば引掻き体1の剛性が低いと引掻き体1の下端側が進行方向と反対方向に反ることによって先端が上方に浮き上がり所定の深さよりも沈み込み深さが浅くなり、更に、引掻き切断部3自体の角度が寝てしまい、言い換えると、引掻き切断部3と泥地面とで成す角度が浅くなり、引掻き切断部3が雑草の根を引掛けずに根の上方を滑るように移動してしまうため、引掻き切断部3が泥地中に所定の深さまで沈み込まず、発芽前の雑草の種が生息する泥地の上層を十分に引っ掻きほぐすことができず、また、泥地地中の上層に張られた根を掻き切ることができず抑草及び除草機能を十分に発揮することができないが、この点、本発明は、引掻き体1を凹凸形状に形成して強度(剛性)を向上させた構成としたので、引掻き切断部3と泥地との接触抵抗によって引掻き体1の下端側が大きく反らず、よって、引掻き切断部3が浮き上がったり角度が寝たりすることなく、略垂下状態で所定の沈み込み深さまで沈み込んで、発芽前の雑草の種が生息する泥地の上層を十分に引っ掻きほぐして発芽を抑制する抑草作業と、既に作物の周囲に生えている雑草の根だけを選択的に掻き切って除草する除草作業とを確実に行うことができる実用性に優れた画期的な抑草除草装置となる。   At this time, for example, if the stiffness of the scratching body 1 is low, the lower end side of the scratching body 1 is warped in the direction opposite to the traveling direction, the tip is lifted upward, and the sinking depth becomes shallower than a predetermined depth. The angle of the part 3 itself goes to sleep, in other words, the angle formed by the scratch cutting part 3 and the muddy ground becomes shallow, and the scratch cutting part 3 moves so as to slide above the root without catching the root of the weed. Therefore, the scratch cutting section 3 does not sink to a predetermined depth in the swamp, and the upper layer of the swamp where the seeds of weeds before germination inhabit can not be sufficiently scratched. Although the roots stretched on the upper layer cannot be scraped off and the function of weeding and weeding cannot be fully exhibited, this point is that the present invention forms the scratched body 1 in an uneven shape to increase the strength (rigidity). Since it has an improved structure, the scratch cutting section 3 and The lower end side of the scratching body 1 does not greatly warp due to the contact resistance with the ground, and therefore the scratch cutting part 3 sinks to a predetermined sinking depth in a substantially suspended state without being lifted or slanted, before germination. Suppressing germination by sufficiently scratching the upper layer of the swamp where the weed species inhabit, and weeding work that selectively weeds only the roots of the weeds already growing around the crop. It is an epoch-making weeding and weeding device excellent in practicality that can be reliably performed.

また、泥地を引っ掻き雑草の根を掻き切る引掻き体1の左右方向の並設間隔は狭いほうが、泥地のより多くの場所を引っ掻くことができ、これにより、より広範囲に渡って抑草作業ができると共に、より確実に多くの雑草の根を掻き切って効率的に除草作業を行うことができるので、引掻き体1の左右方向の並設間隔はできるだけ狭い並設間隔に設定することが好ましいが、引掻き体1の左右方向の並設間隔を狭くすると、例えば水田で使う場合、水田に散在している稲わらや除草した雑草が引掻き体1(引掻き切断部3)に絡みつき易くなり、この絡みついた稲わらや雑草によって引掻き作業部2の先端、即ち、引掻き切断部3間が目詰まり状態になってしまい、この目詰まりした状態で移動すると、折角植えた作物を倒してしまい作物を傷めたり、スムーズに雑草の根を掻き切ることができなくなってしまう為、この引掻き切断部3に絡みついた稲わらや雑草の根を一々排除しなければならないという不具合が生じる。   In addition, the narrower side-by-side spacing between the scratch bodies 1 that scratch the muddy ground and the roots of the weeds can scratch more places in the muddy area, thereby suppressing the weeding work over a wider area. While it is possible to more efficiently scrape off the roots of many weeds and efficiently perform the weeding work, it is preferable to set the side-by-side spacing of the scratching bodies 1 as narrow as possible. For example, when used in a paddy field, rice straw and weeds scattered in the paddy field are easily entangled with the scratching body 1 (scratching cutting part 3). The tip of the scratching section 2, that is, between the scratch cutting sections 3, becomes clogged by rice straw or weeds. Methallyl, smooth in order to no longer be able to as possible off the roots of weeds, a problem that the roots of rice straw and weeds tangled in the scratch-off section 3 must be one by one exclusion occurs.

この点、本発明は、引掻き体1を下方に向けて突設すると共に進行方向と直交する左右方向に並設して形成した引掻き作業部2を進行方向である前後方向に複数並設し、この前後方向に並設した複数の引掻き作業部2のうちの一の引掻き作業部2の引掻き体1に対して、他の引掻き作業部2の引掻き体1を左右いずれかの方向に位置をずらして一の引掻き作業部2の隣り合う二体の引掻き体1間に相当する位置に配設して、一の引掻き作業部2の隣り合う二体の引掻き体1が泥地を引っ掻きながら移動する移動軌跡間を他の引掻き作業部2の引掻き体1が移動するように構成したので、引掻き体1全体が泥地を引っ掻きながら移動する移動軌跡の間隔を、より多くの場所を引っ掻くように狭い間隔に設定しても、各引掻き作業部2を形成する左右方向に並設した引掻き体1の並設間隔は稲わらや雑草が絡みつかず目詰まりを起こさない広さに設定することができ、よって、一々引掻き切断部3に絡みついた稲わらや雑草を排除する作業を行うことなく効率良く抑草及び除草作業を行うことができる画期的な抑草除草装置となる。   In this regard, the present invention has a plurality of scratching working portions 2 formed in parallel in the left-right direction perpendicular to the traveling direction while projecting the scratching body 1 downward, in the front-rear direction, which is the traveling direction, With respect to the scratching body 1 of one of the plurality of scratching work sections 2 arranged side by side in the front-rear direction, the position of the scratching body 1 of the other scratching work section 2 is shifted in either the left or right direction. The two scratching bodies 1 that are adjacent to each other in the one scratching work unit 2 move while scratching the swamp. Since the scratching body 1 of the other scratching working unit 2 moves between the movement trajectories, the interval of the movement trajectory in which the entire scratching body 1 moves while scratching the muddy ground is narrow so as to scratch more places. Even if the interval is set, each scratching work section 2 is formed. The spacing between the scratch bodies 1 arranged side by side in the right direction can be set to an area where rice straw and weeds are not entangled and do not clog, so that the rice straw and weed entangled with the scratch cutting section 3 one by one. It becomes an epoch-making weeding and weeding apparatus which can perform weeding and weeding work efficiently without performing the work which eliminates.

本発明の具体的な実施例について図面に基づいて説明する。   Specific embodiments of the present invention will be described with reference to the drawings.

本実施例は、本発明を抑草除草部5として、この抑草除草部5を、泥地を走行可能な走行体6に設けて、この走行体6が泥地(具体的には水田)を移動することで抑草除草部5が、作物(具体的には稲の苗)が植えられている泥地に生息する発芽前の雑草の種の発芽を抑制する抑草作業と、既にこの泥地に生えている雑草を除草する除草作業との双方の作業を同時に行うように構成した抑草除草装置である。   In the present embodiment, the present invention is referred to as a weed weeding unit 5, and this weeding and weeding unit 5 is provided in a traveling body 6 capable of traveling in a swamp, and this traveling body 6 is a swamp (specifically, paddy field). And the weed control section 5 has already suppressed the germination of pre-emergence weed seeds inhabiting the swamp where the crops (specifically rice seedlings) are planted. It is a weeding and weeding device configured to simultaneously perform both the weeding work for weeding the weeds growing in the swamp.

走行体6は、図1,図2に示すように、フレーム部7と、このフレーム部7に回転自在に設けた走行車輪8と、作業者が把持してこの走行体6の進行方向を操作する操作ハンドル部9とで構成し、更に、この走行体6はフレーム部7に駆動源10を設け、この駆動源10によって走行車輪8が回転して自走可能に構成している。   As shown in FIGS. 1 and 2, the traveling body 6 includes a frame portion 7, traveling wheels 8 that are rotatably provided on the frame portion 7, and an operator gripping and operating the traveling direction of the traveling body 6. Further, the traveling body 6 is provided with a drive source 10 in the frame portion 7, and the traveling wheel 8 is rotated by the drive source 10 so as to be able to self-propel.

また、この駆動源10によって回転する走行車輪8は、円環状の枠体に形成すると共に所定の角度間隔おいて複数の板羽根状突出部11を設けた構成とし、この走行車輪8が回転した際に板羽根状突出部11が泥をかくことにより推進力が生じて走行体6が良好に走行できるように構成している。   The traveling wheel 8 rotated by the drive source 10 is formed in an annular frame and is provided with a plurality of plate blade-like protrusions 11 at predetermined angular intervals, and the traveling wheel 8 is rotated. In this case, the plate blade-like projecting portion 11 is configured such that a propulsive force is generated by removing mud and the traveling body 6 can travel well.

また更に、走行体6の先端側に、この走行体6の前後の重量バランスを調整するバランス調整部20を設けた構成としいている。   Furthermore, the balance adjusting unit 20 for adjusting the weight balance before and after the traveling body 6 is provided on the front end side of the traveling body 6.

具体的には、このバランス調整部20は、重量バランスを調整するための砂等の重量物を収納する収納体から成り、走行体6の先端部に上下方向に回動自在且つ着脱自在に設けた構成としている。   Specifically, the balance adjusting unit 20 is composed of a storage body that stores heavy objects such as sand for adjusting the weight balance, and is provided at the tip of the traveling body 6 so as to be rotatable and detachable in the vertical direction. It has a configuration.

即ち、作業する泥地が比較的固く、走行車輪8が泥地中に沈み込まずに前述した板羽根状突出部11が泥をかかず良好な推進力を生じることができない場合に、このバランス調整部20に砂等の重量物を収納して走行体6の先端側を重くして走行車輪8が泥地に沈み込む易くし、更に沈み込ませたい場合は、このバランス調整部20を下方に回動移動させて前方に突出状態にして、重心をより前方に移動させて走行車輪8を泥地に沈み込み易い状態にすることができ、また、作業する泥地が比較的軟らかく、走行車輪8が泥地中に沈み込み易い場合は、この重量バランス調整部20を取り外して、走行体6の先端側を軽量化することができるように構成している。   That is, when the working muddy ground is relatively hard and the traveling wheel 8 does not sink into the muddy land, the above-described plate blade-like protrusion 11 does not apply mud and cannot produce a good propulsive force. If the heavy load such as sand is stored in the adjusting unit 20 and the tip of the traveling body 6 is made heavy so that the traveling wheel 8 can easily sink into the muddy ground, the balance adjusting unit 20 is moved downward. The center of gravity can be moved further forward so that the traveling wheel 8 can be easily submerged in the swamp, and the swamp working is relatively soft. When the wheel 8 is likely to sink into the muddy ground, the weight balance adjusting unit 20 is removed so that the tip side of the traveling body 6 can be reduced in weight.

また、抑草除草部5は、上述した走行体6の走行車輪8の後方に配設してこの走行体6に牽引されて移動する構成とし、具体的には、走行体6のフレーム部7と操作ハンドル部9とを連結する連結杆12に垂下状態に設けられ、泥地の上層を引っ掻く複数の引掻き体1を下方に向けて突設すると共に進行方向と直交する左右方向に並設して形成した引掻き作業部2を進行方向である前後方向に複数並設し、一の引掻き作業部2の引掻き体1に対して、他の引掻き作業部2の引掻き体1を左右いずれかの方向に位置をずらして一の引掻き作業部2の隣り合う二体の引掻き体1間に相当する位置に配設して、一の引掻き作業部2の隣り合う二体の引掻き体1が泥地を引っ掻きながら移動する移動軌跡間を他の引掻き作業部2の引掻き体1が移動するように構成し、この引掻き体1は、水平方向に出入りする凹凸形状の垂下体に構成すると共に下端に前記泥地中に沈み込ませてこの泥地の上層を引っ掻いたりこの泥地の上層に張られた雑草の根を掻き切ったりする引掻き切断部3を設けた構成とし、この引掻き切断部3は、前記引掻き体1の下端部に水平方向に突設した沈み込み防止部4により、泥地中に張られた雑草の根に到達し且つこの雑草の根よりも深い位置に張られた作物の根に到達しない深さに沈み込むように構成している。   In addition, the weeding and weeding unit 5 is disposed behind the traveling wheel 8 of the traveling body 6 and is moved by being pulled by the traveling body 6, specifically, the frame portion 7 of the traveling body 6. A plurality of scratching bodies 1 for scratching the upper layer of the swamp are provided in a hanging state on the connecting rod 12 that connects the operating handle portion 9 and the operation handle portion 9 and are juxtaposed in the left-right direction perpendicular to the traveling direction. A plurality of the scratching work sections 2 formed in parallel are arranged in the front-rear direction, which is the traveling direction, and the scratching body 1 of the other scratching work section 2 is placed in either the left or right direction with respect to the scratching body 1 of one scratching work section 2. The two scratching bodies 1 adjacent to each other in the one scratching work unit 2 are swamped with the swamps 1 disposed at a position corresponding to between the two scratching bodies 1 adjacent to each other. The scratching body 1 of the other scratching work unit 2 moves between the movement trajectories that move while scratching. The scratching body 1 is configured as an uneven hanging body that goes in and out in the horizontal direction, and the lower end is submerged in the marsh to scratch the upper layer of the marsh or stretch the upper layer of the marsh. The scratch cutting part 3 for scraping the roots of the weeds is provided, and the scratch cutting part 3 is placed in the muddy ground by a subsidence prevention part 4 projecting horizontally at the lower end of the scratching body 1. It is configured to sink to a depth that reaches the roots of the weeds that are stretched on the ground and does not reach the roots of the crops that are deeper than the roots of the weeds.

この抑草除草部5をより具体的に説明すると、引掻き体1は、図3に示すように、一本の線材を進行方向である前後方向に出入りする凹凸状に折曲した凹凸形状の垂下体に構成すると共にこの垂下体の下端を垂下状態に形成した構成として、これを泥地中に沈み込ませてこの泥地の上層を引っ掻いたりこの泥地の上層に張られた雑草の根を掻き切ったりする引掻き切断部3としている。   More specifically describing the weeding and weeding unit 5, as shown in FIG. 3, the scratching body 1 has a concavo-convex shape in which a single wire is bent into a concavo-convex shape that moves in and out in the front-rear direction, which is the traveling direction. It is composed of the body and the lower end of the drooping body is formed in a drooping state so that it is submerged in the swamp and scratches the upper layer of the swamp or scrapes the roots of the weeds stretched on the upper layer of the swamp. It is set as the scratch cutting part 3 to cut.

また、この引掻き体1は、下端に設けた引掻き切断部3の泥地中への沈み込み深さを、泥地中に張られた雑草の根には到達するがこの雑草の根よりも深い位置に張られた作物の根には到達しない深さに制御する沈み込み防止部4を設けた構成とし、この沈み込み防止部4は、引掻き切断部3の基端に、引掻き切断部3に対して進行方向(前方)に突出状態に設けた構成とし、本実施例では、進行方向である前後方向に向けて凹凸状に折曲した凹凸状引掻き体1の最下端に位置する進行方向に向かって凸となる凸状部の上下に対向する突出辺部の下側を沈み込み防止部4としている。   Further, the scratching body 1 reaches the root of the weed stretched in the swamp with the depth of subsidence of the scratch cutting portion 3 provided at the lower end in the swamp, but at a position deeper than the root of the weed. The subsidence prevention unit 4 is provided to control the depth so as not to reach the root of the stretched crop. The subsidence prevention unit 4 is located at the base end of the scratch cutting unit 3 with respect to the scratch cutting unit 3. It is set as the structure provided in the protrusion state in the advancing direction (front), and, in a present Example, toward the advancing direction located in the lowest end of the uneven | corrugated scratch body 1 bent into an uneven | corrugated shape toward the front-back direction which is an advancing direction. The lower side of the protruding side part that faces the upper and lower sides of the convex part that is convex is the sinking prevention part 4.

また、この沈み込み防止部4は、非作業時、即ち、引掻き切断部3が泥地と接してなく引掻き体1が垂下状態の際に前上がりの傾斜状態となるように設けた構成とし、作業時、即ち、引掻き体1の下端に設けた引掻き切断部3が泥地を引っ掻きながら移動する際に生じる抵抗によって引掻き体1が弓状に反り、この引掻き体1が弓状に反ることで沈み込み防止部4の後方側が持ち上がった際に、泥地の表面と略平行になるように構成している。   In addition, the subsidence prevention unit 4 is configured so as to be in an upwardly inclined state when not in operation, that is, when the scratch cutting unit 3 is not in contact with the muddy ground and the scratching body 1 is in a suspended state, During the operation, that is, when the scratch cutting part 3 provided at the lower end of the scratching body 1 moves while scratching the swamp, the scratching body 1 warps in an arcuate shape, and the scratching body 1 warps in an arcuate shape. When the rear side of the subsidence prevention part 4 is lifted up, it is configured to be substantially parallel to the surface of the swamp.

即ち、沈み込み防止部4が泥地表面と平行となることで、泥地との接地面積が最大となって沈み込み防止部4の泥地に対する抵抗が最大となることでこの沈み込み防止部4が泥地中に沈み込まず、これによって、引掻き切断部3が所定以上の沈み込み深さとならないように構成している。   That is, since the subsidence prevention unit 4 is parallel to the swamp surface, the ground contact area with the swamp is maximized and the resistance of the subsidence prevention unit 4 to the mud is maximized. 4 is not submerged in the muddy ground, so that the scratch cutting part 3 does not have a predetermined depth or more.

具体的には、引掻き体1の凹凸形状を、開口部側が幅広となる台形状凹凸形状、より具体的には、凹凸形状の進行方向に向かって凸となる凸状部の上下に対向する突出辺部が、上側の突出辺部を前下がり状態、下側の突出辺部を前上がり状態としてハ字状に形成して、この凹凸形状の進行方向に向かって凸となる凸状部の下側の突出辺部から成る沈み込み防止部4を前上がり状態に設けた構成としている。   Specifically, the uneven shape of the scratching body 1 is a trapezoidal uneven shape in which the opening side is wide, more specifically, a protrusion that is opposed to the top and bottom of the convex portion that is convex toward the traveling direction of the uneven shape. The side part is formed in a C shape with the upper protruding side part in the forwardly lowered state and the lower protruding side part in the forwardly raised state, and is below the convex part that is convex in the direction of travel of the uneven shape. It is set as the structure which provided the sinking prevention part 4 which consists of a protrusion side part of the side in the front rising state.

また更に、この沈み込み防止部4は、泥地中に沈み込む引掻き切断部3の先端部から5mm〜15mm(本実施例では約10mm)の位置に配設した構成とし、引掻き切断部3の泥地中への沈み込み深さが5mm〜15mm(本実施例では約10mm)となるようにしている。   Furthermore, the subsidence prevention unit 4 is arranged at a position of 5 mm to 15 mm (about 10 mm in this embodiment) from the tip of the scratch cutting unit 3 that sinks into the muddy ground. The depth of sinking into the swamp is set to 5 mm to 15 mm (about 10 mm in this embodiment).

即ち、本実施例の引掻き切断部3の沈み込み深さは、泥地、具体的には水田の上層側、10mm前後の深さに生息している発芽前の雑草の種の安定した環境を荒らして位置をずらすなど不安定な環境にすると共に、約30mmの深さ位置から下方に向けて根を張る稲の苗の根には到達せず、この泥地(水田)の上層側の5mm〜10mmの深さに根を張るヒエ等の水田に生える一般的な雑草の根に確実に到達してこの雑草の根だけを選択的に掻き切るように構成している。   That is, the submergence depth of the scratch cutting part 3 of the present embodiment is a stable environment of the seeds of weeds before germination that inhabit the muddy land, specifically, the upper layer side of the paddy field, about 10 mm deep. In addition to the unstable environment such as roughing and shifting the position, it does not reach the roots of the rice seedlings that extend downward from a depth of about 30 mm, and it is 5 mm on the upper layer side of this swamp (paddy field). It is configured to surely reach the roots of general weeds that grow in paddy fields such as Japanese millet that have roots at a depth of 10 mm, and selectively cut only the roots of these weeds.

また、本実施例は、上述のように構成した引掻き体1を下方に向けて突設すると共に進行方向と直交する左右方向に並設して形成した引掻き作業部2を形成すると共に、この引掻き作業部2を進行方向である前後方向に複数並設した構成としている。   Further, the present embodiment forms a scratching working unit 2 formed by projecting the scratching body 1 configured as described above downward and in parallel in the left-right direction perpendicular to the traveling direction, and this scratching. It is set as the structure which arranged the working part 2 in parallel in the front-back direction which is an advancing direction.

具体的には、引掻き作業部2は三列以上並設し、一の引掻き作業部2の隣り合う二体の引掻き体1が泥地を引っ掻きながら移動する移動軌跡間隔を他の引掻き作業部2の引掻き体1によって三分割以上に分割するように一の引掻き作業部2の引掻き体1に対して他の引掻き作業部2の引掻き体1を左右いずれかの方向に位置をずらして配設した構成とすることが好ましく、本実施例では、この引掻き作業部2を三列設け、一の引掻き作業部2の隣り合う二体の引掻き体1が泥地を引っ掻きながら移動する移動軌跡間隔を他の引掻き作業部2の引掻き体1によって三分割するように一の引掻き作業部2の引掻き体1に対して他の引掻き作業部2の引掻き体1を左右いずれかの方向に位置をずらして配設した構成としている。   Specifically, the scratching work units 2 are arranged in parallel in three or more rows, and the distance between the movement trajectories in which two adjacent scratching bodies 1 of the one scratching work unit 2 move while scratching the muddy ground is set to the other scratching work units 2. The scratching body 1 of the other scratching work part 2 is arranged with its position shifted in either the left or right direction with respect to the scratching body 1 of one scratching work part 2 so that the scratching body 1 is divided into three or more parts. In the present embodiment, this scratching working unit 2 is provided in three rows, and the two moving scratching units 1 adjacent to one scratching working unit 2 move while scratching the swamp. The scratching body 1 of the other scratching work section 2 is shifted in either the left or right direction with respect to the scratching body 1 of one scratching work section 2 so as to be divided into three parts by the scratching body 1 of the scratching work section 2. The configuration is set up.

より詳細に説明すると、各引掻き作業部2は、進行方向と直交する左右方向が長さ方向となるように配設した横杆体13に複数の引掻き体1を等間隔で並設状態に垂設した構成とし、また、この引掻き体1の並設間隔は、泥地中に沈み込んだ引掻き切断部3に水田に散在する稲わらや根を掻き切って除草した雑草が絡みつき左右方向に隣り合う引掻き切断部3の間が目詰まりを起こさない間隔、具体的には約4cm以上に設定しており、本実施例では4.5cmに設定に設定している。   Explaining in more detail, each scratching working unit 2 is provided with a plurality of scratching bodies 1 arranged in parallel at equal intervals on a horizontal casing 13 arranged so that the horizontal direction perpendicular to the traveling direction is the length direction. In addition, the side-by-side spacing of the scraping bodies 1 is adjacent to the left and right direction because weeds weeded by scraping the rice straw and roots scattered in the paddy field to the scratch cutting section 3 submerged in the muddy land. The interval between the scratch cutting portions 3 is set to an interval at which clogging does not occur, specifically about 4 cm or more. In the present embodiment, the interval is set to 4.5 cm.

また、図3に示すように、三列に並設した夫々の引掻き作業部2を形成する引掻き体1の配設位置を、一列目(図中手前側)の引掻き作業部2Aに対して二列目の引掻き作業部2Bを所定量左右いずれかの方向に位置をずらして配設し、三列目の引掻き作業部2Cは、二列目の引掻き作業部2Bよりも更に所定量、同方向に位置をずらして配設している。   Further, as shown in FIG. 3, the arrangement positions of the scratching bodies 1 forming the respective scratching working sections 2 arranged in parallel in three rows are set at two positions with respect to the scratching working section 2A in the first row (front side in the figure). The row scratching unit 2B is disposed by shifting the position in the left or right direction by a predetermined amount, and the third row scratching unit 2C is further in the same direction by a predetermined amount than the second row scratching unit 2B. The positions are shifted from each other.

具体的には、二列目の引掻き作業部2Bの引掻き体1Bは、一列目の引掻き作業部2Aの引掻き体1Aに対して抑草除草部5の後方側から見た際に右方向(走行体6側から見た場合は左方向)へ1.5cm位置をずらして配設し、三列目の引掻き作業部2Cの引掻き体1Cは、二列目の引掻き作業部2Bの引掻き体1Bに対して抑草除草部5の後方側から見た際に右方向(走行体6側から見た場合は左方向)へ1.5cm、即ち一列目の引掻き作業部2Aの引掻き体1Aに対して3cm位置をずらして配設している。   Specifically, the scratching body 1B of the second row of the scratching working unit 2B is directed rightward (running) when viewed from the rear side of the weeding and weeding unit 5 with respect to the scratching unit 1A of the first row of the scratching working unit 2A. The left side (when viewed from the body 6 side) is shifted by 1.5 cm, and the scratching body 1C of the third row of the scratching work unit 2C is connected to the scratching body 1B of the second row of the scratching work unit 2B. On the other hand, when viewed from the rear side of the weed control unit 5, it is 1.5 cm in the right direction (left direction when viewed from the traveling unit 6 side), that is, with respect to the scratching unit 1A of the first scratching unit 2A. The position is shifted by 3 cm.

即ち、この三列の引掻き作業部2を形成する引掻き体1を前後方向から見た際に、一列目の引掻き作業部2Aの引掻き体1Aの隣り合う引掻き体1Aの間に二列目の引掻き作業部2Bの引掻き体1Bと三列目の引掻き作業部2Cの引掻き体1Cが等間隔で配置し、この一列目の引掻き作業部2Aの隣り合う二本の引掻き体1Aの間隔を二列目と三列目の引掻き作業部2B,2Cの引掻き体1B,1Cによって三等分したように見えるように構成している。   That is, when the scratching bodies 1 forming the three rows of the scratching working sections 2 are viewed from the front and rear directions, the second row of scratches is placed between the adjacent scratching bodies 1A of the scratching bodies 1A of the first row of scratching working sections 2A. The scratching body 1B of the working unit 2B and the scratching unit 1C of the third row of the scratching working unit 2C are arranged at equal intervals, and the interval between the two adjacent scratching units 1A of the first row of the scratching working unit 2A is the second row. And the scratching work sections 2B and 2C in the third row are configured to appear to be divided into three equal parts by the scratching bodies 1B and 1C.

更に言い換えると、この三列の引掻き作業部2を形成する引掻き体1を前後方向から見た際の引掻き体1の並設状態が、端から一列目の引掻き作業部2Aの引掻き体1A、二列目の引掻き作業部2Bの引掻き体1B、三列目の引掻き作業部2Cの引掻き体1Cの並び順を繰り返しながら等間隔(1.5cm間隔)に並設している状態に見えるように構成している。   Furthermore, in other words, the side-by-side state of the scratching bodies 1 when the scratching bodies 1 forming the three rows of the scratching working sections 2 are viewed from the front-rear direction is the scratching bodies 1A, 2 of the scratching working sections 2A in the first row from the end. It is configured so that it can be seen as being arranged side by side at equal intervals (1.5 cm intervals) while repeating the arrangement order of the scratching bodies 1B of the row scratching operation unit 2B and the scratching unit 1C of the third row scratching operation unit 2C. doing.

また、引掻き作業部2を形成する引掻き体1を設けた横杆体13は、前後方向に三列、所定の間隔を置いて並設した状態で複数の補強リブ14を架設状態に設けて連結し、この補強リブ14によって、夫々の横杆体13(引掻き作業部2)が、引掻き切断部3が泥地を引っ掻きながら移動する際の抵抗によって位置がよじれてしまうことを防止し、この引掻き作業部2となる横杆体13が常に平行状態を保持して、引掻き体1の並設間隔が一定となるように構成している。   Further, the horizontal frame 13 provided with the scratching body 1 forming the scratching working unit 2 is connected in a state where a plurality of reinforcing ribs 14 are installed in a state of being arranged in parallel in three rows in the front-rear direction at a predetermined interval. The reinforcing ribs 14 prevent each lateral frame 13 (scratching work part 2) from being kinked by the resistance when the scratch cutting part 3 moves while scratching the muddy ground. The horizontal rod 13 which becomes 2 always maintains the parallel state, and the arrangement interval of the scratch bodies 1 is constant.

また、この横杆体13は、左右両端側を折り畳み収納自在に構成して、この横杆体13を折り畳み収納して収納時の収納スペースや運搬時の載置スペースを確保し易い状態にできる構成としている。   In addition, the horizontal housing 13 is configured so that the left and right ends can be folded and stored, and the horizontal housing 13 can be folded and stored to easily secure a storage space during storage and a mounting space during transportation. Yes.

具体的には、図4に示すように、横杆体13を分割し、夫々の横杆体13を枢着部15を介して連結し、この枢着部15よりも外側の横杆体13を、枢着部15を支点に上下回動自在に設けてこの横杆体13を折り畳み収納自在に構成している。   Specifically, as shown in FIG. 4, the horizontal body 13 is divided, and the respective horizontal bodies 13 are connected to each other via the pivoting portions 15. The horizontal housing 13 is configured to be foldable and retractable by providing a landing portion 15 as a fulcrum so as to be rotatable up and down.

より具体的には、この上下回動自在に設けた枢着部15よりも外側の横杆体13は、非折り畳み収納状態、即ち内側の横杆体13と一直線状になっている状態では、この外側の横杆体13に設けた回動阻止当接部17が枢着部15の上方に挿脱自在に配設した係止ピン16に当接して回動不能となり内側の横杆体13と一直線状を成す状態を保持し、折り畳み収納状態では、外側の横杆体13の端部が係止ピン16に当接して回動不能となり折り畳み収納状態を保持するように構成し、また、この係止ピン16を抜き取ることで外側の横杆体13が回動動作可能となる構成としている。   More specifically, the outer horizontal body 13 from the pivoting portion 15 provided so as to be pivotable up and down is in an unfolded storage state, that is, in a state of being aligned with the inner horizontal body 13, The rotation prevention abutting portion 17 provided on the horizontal rod body 13 comes into contact with a locking pin 16 that is detachably disposed above the pivoting portion 15 so that it cannot rotate and is in a straight line with the inner horizontal rod body 13. In the folded and stowed state, the end of the outer lateral housing 13 abuts against the locking pin 16 so that it cannot rotate, and is held in the folded and stowed state. The outer lateral laying body 13 is configured to be able to rotate.

また、本実施例は、引掻き切断部3の沈み込み深さをより確実に略一定の沈み込み深さを保持するために、抑草除草部5を荷重吸収装置18(サスペンション)を介して連結杆12に設けて抑草除草部5が上方から押圧されることで下方に押し下がらないようにすると共に、抑草除草部5自体の沈み込みを抑制するフロート部19を設けた構成としている。   Further, in the present embodiment, the weeding and weeding unit 5 is connected via a load absorbing device 18 (suspension) in order to more surely maintain the subsidence depth of the scratch cutting unit 3 more reliably. The float 12 is provided on the ridge 12 so as not to be pushed downward when the weed weed removal unit 5 is pressed from above, and the float unit 19 is provided to suppress the sinking of the weed weed removal unit 5 itself.

具体的には、抑草除草部5を構成する横杆体13と連結杆12の間に荷重吸収装置18としてのバネ材18を設け、連結杆12に、この連結杆12を下方側に押圧する荷重がかかりこの連結杆12が下方側に移動した際、この連結杆12と横杆体13との間に設けたバネ材18が収縮して荷重を吸収することで、この連結杆12からの荷重が抑草除草部5に伝達されず、これにより、連結杆12は下方に移動しても、抑草除草部5は下方に沈み込まない構成としている。   Specifically, a spring material 18 as a load absorbing device 18 is provided between the horizontal rod 13 constituting the weed control unit 5 and the connecting rod 12, and the connecting rod 12 is pressed downward on the connecting rod 12. When a load is applied and the connecting rod 12 moves downward, the spring material 18 provided between the connecting rod 12 and the horizontal rod 13 contracts to absorb the load, so that the load from the connecting rod 12 is reduced. Is not transmitted to the weed weeding unit 5, so that even if the connecting rod 12 moves downward, the weed weeding unit 5 does not sink downward.

より具体的には、抑草除草部5の横杆体13に、棒状に形成した複数の抑草除草部側係合部21を突設し、走行体6の連結杆12に、円環状に形成した走行体側係合部22を設け、抑草除草部側係合部21にバネ材18を嵌挿した状態で、この抑草除草部側係合部21を走行体側係合部22の下方側から挿入して、この走行体側係合部22がバネ材18に支持されるように構成し、この走行体側係合部22が下方に移動するとバネ材18が縮退しこの走行体側係合部22の荷重を吸収して抑草除草部側係合部21に荷重を伝達しないことで抑草除草部5の沈み込みを防止するように構成している。   More specifically, a plurality of weed weeding side engaging portions 21 formed in a rod shape project from the horizontal rod 13 of the weed weeding portion 5 and formed in an annular shape on the connecting rod 12 of the traveling body 6. In the state where the traveling body side engaging portion 22 is provided and the spring material 18 is fitted and inserted into the weeding weeding portion side engaging portion 21, the weeding and weeding portion side engaging portion 21 is disposed below the traveling body side engaging portion 22. So that the traveling body side engaging portion 22 is supported by the spring material 18, and when the traveling body side engaging portion 22 moves downward, the spring material 18 is degenerated and the traveling body side engaging portion 22 is supported. The load is not transmitted to the engaging portion 21 on the side of the weeding and weeding portion so that the weeding and weeding portion 5 is prevented from sinking.

尚、本実施例は、抑草除草部側係合部21に走行体側係合部22の移動を抑止するストッパーを配設し得る構成とし、抑草除草部側係合部21と係合状態の走行体側係合部22を挟み込むようにストッパーを配設することで、荷重吸収装置18(バネ材18)の機能を不能にして走行体側係合部22からの荷重を抑草除草部側係合部21に伝達することもできるように構成している。   In this embodiment, the weeding and weeding portion side engaging portion 21 can be provided with a stopper that suppresses the movement of the traveling body side engaging portion 22 and is engaged with the weeding and weeding portion side engaging portion 21. By disposing the stopper so as to sandwich the traveling body side engaging portion 22 of the vehicle, the function of the load absorbing device 18 (spring material 18) is disabled, and the load from the traveling body side engaging portion 22 is applied to the weeding and weeding portion side. It is configured to be able to transmit to the joint portion 21.

即ち、固めの泥地など引掻き切断部3が沈み込み難い場合に、操作ハンドル部9に荷重をかけて抑草除草部5を下方に押し込むことで引掻き切断部3を所定の沈み込み深さまで沈み込ませることができるように構成している。   That is, when the scratch cutting part 3 is hard to sink, such as hard mud, the scratch cutting part 3 sinks to a predetermined sinking depth by applying a load to the operation handle part 9 and pushing the weeding and weeding part 5 downward. It is configured so that it can be inserted.

また、フロート部19は、泥地との接地面積が大きくなるように板状に形成すると共に抑草除草部5の左右両側に一体ずつ配設した構成とし、更に、このフロート部19は、左右方向に移動自在に設けた構成としこの二体のフロート部19の間隔を調整自在に構成して、田植え後の水田で使用する際、苗をフロート部19で倒さないように苗の植え付け間隔(30cm若しくは33cm)に合わせてこの二体のフロート部19の間隔を調整できる構成としている。   Further, the float portion 19 is formed in a plate shape so as to increase the contact area with the muddy ground, and is configured to be integrally disposed on both the left and right sides of the weed weed removal portion 5. It is configured to be freely movable in the direction, and the interval between the two float parts 19 is configured to be adjustable. When used in a paddy field after planting rice, the seedling planting interval ( 30 cm or 33 cm), the distance between the two float portions 19 can be adjusted.

また更に、このフロート部19は、上下方向に移動自在に設けて高さ調整自在に構成して、このフロート部19の位置を調整することで、引掻き切断部3の沈み込み深さを調整し得る構成としている。   Furthermore, the float portion 19 is provided so as to be movable in the vertical direction so that the height can be adjusted. By adjusting the position of the float portion 19, the sinking depth of the scratch cutting portion 3 can be adjusted. The structure is to get.

即ち、このフロート部19の位置を調整することで、前述した泥地の上層10mm程度の深さよりも深い層、例えば、20mm程度の深さのところを引っ掻くことも可能となり、より多くの雑草の発芽を抑制することができるように構成している。   In other words, by adjusting the position of the float portion 19, it becomes possible to scratch a layer deeper than the above-mentioned depth of about 10 mm, for example, a depth of about 20 mm. It is comprised so that germination can be suppressed.

上述のように構成した本実施例の作用・効果について以下に説明する。   The operation and effect of the present embodiment configured as described above will be described below.

田植え後の水田に雑草が生えないようにする抑草作業と、既に生えている雑草を除草する除草作業を行うために、本実施例を水田に配置すると、抑草除草部5の前後方向に並設する三列の引掻き作業部2を形成する複数の引掻き体1の下端に設けた引掻き切断部3が泥地中に所定の深さまで沈み込む。   When this embodiment is arranged in a paddy field in order to prevent weeds from growing on paddy fields after planting and weeding work to remove weeds that have already grown, A scratch cutting section 3 provided at the lower end of a plurality of scratch bodies 1 forming three rows of scratch working sections 2 arranged side by side sinks to a predetermined depth in the muddy ground.

即ち、引掻き切断部3は、この引掻き切断部3の基端に設けた沈み込み防止部4が泥地面に対して生ずる接地抵抗によって沈み込まないため、引掻き切断部3の沈み込み深さはこの引掻き切断部3の基端に設けた沈み込み防止部4よりも先端側の部分しか沈み込まないこととなる。   That is, in the scratch cutting section 3, the sinking prevention section 4 provided at the base end of the scratch cutting section 3 does not sink due to the grounding resistance generated on the muddy ground. Only the portion on the tip side of the sinking prevention portion 4 provided at the base end of the scratch cutting portion 3 sinks.

更に、抑草除草部5自体もフロート部19によって泥地中に沈み込まない構成としたので、この抑草除草部5が泥地中に沈み込まないことで、より確実に引掻き切断部3の沈み込み深さを一定の沈み込み深さに保持することができる。   Furthermore, since the weed weeding unit 5 itself is configured not to sink into the swamp by the float unit 19, the suppression weeding unit 3 of the scratch cutting unit 3 can be more reliably prevented from sinking into the swamp. The sinking depth can be maintained at a fixed sinking depth.

よって、引掻き切断部3は、沈み込み防止部4とフロート部19によって、発芽前の雑草の種が生息する泥地の上層付近で、泥地に生えている雑草の根には到達するがこの雑草の根よりも深い位置に張られているこの泥地に栽培している作物の根には到達しない深さ(具体的には、泥地表面から10mmの深さ)まで沈み込んだ状態となる。   Therefore, the scratch cutting unit 3 reaches the roots of the weeds growing in the swamp in the vicinity of the upper layer of the swamp where the seeds of weeds before germination live by the subsidence prevention unit 4 and the float unit 19. It is in a state where it is submerged to a depth that does not reach the root of the crop cultivated in the swamp that is stretched deeper than the grass root (specifically, a depth of 10 mm from the swamp surface).

この引掻き切断部3が泥地中に所定の深さに沈み込んだ状態で走行体6を移動させると、この走行体6に牽引されて抑草除草部5が牽引走行し、この抑草除草部5が走行することで、図5(a)〜(c)に示すように、引掻き切断部3が、泥地の上層を引っ掻きながら移動することとなり、これによって、泥地の上層側が耕されたようにほぐれた状態となり、安定した状態で埋まっている発芽前の雑草の種の環境を不安定にして雑草の発芽を抑制する抑草作業と、既に泥地に生えている雑草の根を掻き切って除草する除草作業の双方の作業を同時に行うこととなる。   When the traveling body 6 is moved in a state where the scratch cutting section 3 is submerged in the muddy ground, the weeding and weeding section 5 is pulled by the traveling body 6 and this weeding and weeding is performed. As part 5 travels, as shown in FIGS. 5 (a) to 5 (c), scratch cutting unit 3 moves while scratching the upper layer of the swamp, thereby cultivating the upper layer side of the swamp. Suppressing weed germination by destabilizing the environment of pre-emergence weed seeds that are loosened and stable, and scraping the roots of weeds already growing in the swamp Both the weeding work to cut and weed will be performed at the same time.

しかも、本実施例を水田で使用した場合、引掻き体が泥地を引っ掻くことでこの水田の上層の泥が水中に撹拌されて水面が泥水状に濁るので、発芽前の雑草に対して日光の照射率を低下することができ、これによって、雑草の発芽を抑制することができる画期的な抑草除草装置となる。   Moreover, when this embodiment is used in paddy fields, the scratching body scratches the swamp, and the upper mud of this paddy field is agitated in the water, and the water surface becomes muddy. The irradiation rate can be reduced, thereby providing an epoch-making weeding and weeding apparatus capable of suppressing weed germination.

また、下端に引掻き切断部3を設けた引掻き体1は、移動時は、引掻き切断部3が泥地を引っ掻きながら移動する際の抵抗によって、下端側を引きずるような弓状に変形する力を受ける。   In addition, the scratching body 1 provided with the scratch cutting part 3 at the lower end has a force that deforms into an arcuate shape that drags the lower end side due to resistance when the scratch cutting part 3 moves while scratching the swamp. receive.

この際、例えば引掻き体1の剛性が低いと引掻き体1の下端側が進行方向と反対方向に反ることによって先端が上方に浮き上がり所定の深さよりも沈み込み深さが浅くなり、更に、引掻き切断部3自体の角度が寝てしまい、言い換えると、引掻き切断部3と泥地面とで成す角度が浅くなり、引掻き切断部3が雑草の根を引掛けずに根の上方を滑るように移動してしまうため、引掻き切断部3が泥地中に所定の深さまで沈み込まず、発芽前の雑草の種が生息する泥地の上層を十分に引っ掻きほぐすことができず、また、泥地地中の上層に張られた根を掻き切ることができず抑草及び除草機能を十分に発揮することができないが、この点、本実施例は、引掻き体1を凹凸形状に形成して強度(剛性)を向上させた構成としたので、引掻き切断部3と泥地との接触抵抗によって引掻き体1の下端側が大きく反らず、よって、引掻き切断部3が浮き上がったり角度が寝たりすることなく、略垂下状態で所定の沈み込み深さまで沈み込んで、発芽前の雑草の種が生息する泥地の上層を十分に引っ掻きほぐして発芽を抑制する抑草作業と、既に作物の周囲に生えている雑草の根だけを選択的に掻き切って除草する除草作業とを確実に行うことができる実用性に優れた画期的な抑草除草装置となる。   At this time, for example, if the stiffness of the scratching body 1 is low, the lower end side of the scratching body 1 is warped in the direction opposite to the traveling direction, the tip is lifted upward, and the sinking depth becomes shallower than a predetermined depth. The angle of the part 3 itself goes to sleep, in other words, the angle formed by the scratch cutting part 3 and the muddy ground becomes shallow, and the scratch cutting part 3 moves so as to slide above the root without catching the root of the weed. Therefore, the scratch cutting section 3 does not sink to a predetermined depth in the swamp, and the upper layer of the swamp where the seeds of weeds before germination inhabit can not be sufficiently scratched. Although the roots stretched on the upper layer cannot be scraped off and the function of weeding and weeding cannot be fully exerted, in this respect, in this example, the scratched body 1 is formed in an uneven shape to provide strength (rigidity). Since the structure is improved, the scratch cutting section 3 The lower end side of the scratching body 1 is not greatly warped due to the contact resistance with the muddy ground, so that the scratch cutting part 3 sinks to a predetermined subsidence depth in a substantially suspended state without being lifted or slanted, and germinates. Suppressing germination by sufficiently scratching the upper layer of the swamp where the previous weed seeds inhabit, and weeding work to selectively weed and remove only the roots of the weeds already around the crop It is an epoch-making weeding and weeding device with excellent practicality.

また、本実施例は、三列に並設した夫々の引掻き作業部2を形成する引掻き体1の配設を、二列目の引掻き作業部2Bの引掻き体1Bは、一列目の引掻き作業部2Aの引掻き体1Aに対して1.5cm位置をずらして配設し、三列目の引掻き作業部2Cの引掻き体1Cは、二列目の引掻き作業部2Bの引掻き体1Bに対して1.5cm、即ち一列目の引掻き作業部2Aの引掻き体1Aに対して3cm位置をずらして配設し、この三列の引掻き作業部2を形成する引掻き体1を前後方向から見た際に、一列目の引掻き作業部2Aの隣り合う引掻き体1Aの間に二列目の引掻き作業部2Bの引掻き体1Bと三列目の引掻き作業部2Cの引掻き体1Cとが等間隔で配置し、この一列目の引掻き作業部2Aの隣り合う二本の引掻き体1Aの間隔を二列目と三列目の引掻き作業部2B,2Cの引掻き体1B,1Cによって三等分したように見えるように構成したので、夫々の引掻き作業部2を形成する引掻き体1の並設間隔は広く設定できこれによって稲わらや根を掻き切って除草した雑草が引っ掛かり難くなり目詰まりが起こらず、また、引掻き体1が泥地を引っ掻く間隔は狭く、泥地のより多くの場所を引っ掻くことができ、これにより、泥地を隈なく抑草作業することができると共に、より多くの雑草の根を掻き切って効率良く除草作業を行うことができる実用性に優れた画期的な抑草除草装置となる。   Further, in this embodiment, the arrangement of the scratching bodies 1 forming the respective scratching working sections 2 arranged in parallel in three rows is different from the arrangement of the scratching bodies 1B in the second row of the scratching working sections 2B. The scratching body 1C of the third row of the scratching working unit 2C is arranged at a distance of 1.5 cm with respect to the 2A scratching unit 1A, and the scratching unit 1B of the second row of the scratching working unit 2B is 1. 5 cm, that is, when the scratching bodies 1 forming the three rows of the scratching working parts 2 are viewed from the front and rear direction, the first row of the scratching working parts 2A is arranged at a position shifted by 3 cm from the scratching body 1A of the first row of the scratching working parts 2A. Between the adjacent scratch bodies 1A of the eye scratch working section 2A, the scratch bodies 1B of the second row scratch working section 2B and the scratch bodies 1C of the third row scratch working section 2C are arranged at equal intervals. Two rows of two scratching bodies 1A adjacent to each other in the scratching part 2A of the eye And the scratching work sections 2B and 2C in the third row are configured to appear to be divided into three equal parts by the scratching bodies 1B and 1C, so that the spacing between the scratching bodies 1 forming the respective scratching work sections 2 is set wide. As a result, weeds weeded by weeding rice straw and roots will not be caught and clogging will not occur, and the scratching body 1 will scratch the swamp so that it can scratch more places in the swamp. This makes it possible to work on the swamps without hesitation, and to break down the roots of more weeds and efficiently carry out the weeding work. Become.

更に、本実施例は、抑草除草部5の横杆体13を折り畳み収納自在に構成したので、収納時や運搬時にコンパクトにでき、収納スペースや設置スペースを要せず収納性に優れた画期的な抑草除草装置となる。   Furthermore, in this embodiment, the horizontal rod body 13 of the weeding and weeding section 5 is configured to be foldable and retractable, so that it can be compacted during storage and transportation, and it has an excellent storage property without requiring storage space or installation space. It becomes a typical weed control device.

また更に、本実施例は抑草除草部5を、荷重吸収装置18としてのバネ材18を介して連結杆12に設けたので、連結杆12に、この連結杆12を下方側に押圧する荷重がかかりこの連結杆12が下方側に移動しても、この連結杆12と横杆体13との間に設けたバネ材18が収縮して荷重を吸収することで、この連結杆12からの荷重が抑草除草部5に伝達されず、連結杆12は下方に移動しても抑草除草部5は下方に沈み込まないので、この抑草除草部5を構成する引掻き体1も沈み込まず、よって、引掻き切断部3が所定の沈み込み深さ以上に深く沈み込むことが無く、雑草よりも深い位置に根を張る作物の根に引掻き切断部3が到達して根を掻き切る心配がない実用性に優れた抑草除草装置となる。   Furthermore, in this embodiment, since the weed control unit 5 is provided on the connecting rod 12 via the spring material 18 as the load absorbing device 18, the load that presses the connecting rod 12 downward on the connecting rod 12. Even if the connecting rod 12 is moved downward, the spring material 18 provided between the connecting rod 12 and the horizontal rod body 13 contracts to absorb the load, so that the load from the connecting rod 12 is reduced. Is not transmitted to the weeding and weeding unit 5, and even if the connecting rod 12 moves downward, the weeding and weeding unit 5 does not sink downward, so that the scratching body 1 constituting the weeding and weeding unit 5 does not sink. Therefore, the scratch cutting part 3 does not sink deeper than a predetermined subsidence depth, and there is a concern that the scratch cutting part 3 will reach the root of the crop that has roots deeper than the weeds and the root will be scraped off. It becomes a non-practical herbicidal weeding device.

尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。   Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
