【発明の属する技術分野】
本発明は、成形した畝の表層部を雑草が生えにくいように処理する畝表層部処理装置に関するものである。
【0002】
【従来の技術】
従来、下記特許文献1に示されるように、ビニール製マルチフィルムを畝に被覆する装置を設けたものがあり、これにより畝から雑草が生えるのを抑制するものがあった。
【0003】
また、下記特許文献2に示されるように、成形された畝の表面部をスリップ回転する回転体を設けて、畝の表面部を締め固める装置があり、これにより畝を崩れ難くしたものがあった。

【0006】
【発明が解決しようとする課題】
上記従来技術の前者のものは、栽培終了後の除去作業が煩わしく、また、ビニール製マルチフィルムが腐敗しないため、それを焼却する際に生じるガスが環境問題にもなっている。なお、後者のものは、畝の表面部を締め固めて畝の崩れを少なくするのであるが、マルチフィルムで覆った畝のように雑草が生えるのを抑制することができない。そこで、本発明は、ビニール製マルチシートで畝を覆うことなく、畝から雑草が生えるのを良好に抑制して、マルチシートの除去作業を解消して農作業の労力軽減を図り、マルチシート廃棄時の環境問題を解消することを課題とする。
【0007】
【課題を解決するための手段】
本発明は、上記課題を解決するために、以下のような技術的手段を講じた。
請求項1に係る発明は、自走車体(1)に、畝立て装置(2)と液体散布手段と回転体(18)を装着するものであって、畝立て装置(2)で成形された畝に沿って移動しながら畝上面に液体を散布する液体散布手段と、畝に沿って移動しながら畝の表層部に接触して自走車体(1)が畝に沿って移動する速度よりも大なる周速度で回転しかつこの回転する速度が変速可能に構成され前記液体散布手段により散布された液体を含んだ畝の表層部の土を練り土状にする回転体(18)とを設けた畝表層部処理装置において、前記液体散布手段は、水に除草剤、凝固剤又はパルプ溶液を混合した液体の液体タンク(19a)、ポンプ(20a)、該液体タンク(19a)からポンプ(20a)に液体を供給する供給ホース(19b)、ポンプ(20a)から吐出する液体を散布ノズル(21,…)に送る移送ホース(20b)、前記回転体(18)の上方に左右所定間隔を隔てて配置されていて回転体(18)の外周面に液体を散布する散布ノズル(21,…)を備えた畝表層部処理装置としたものである。
【0008】
【0009】
【作用及び発明の効果】
請求項1に係る発明により、畝の表層部は練土状に処理されるので、処理後その表層部が乾燥して硬くなり、畝の表面が硬い土の板で覆われた状態となる。これにより、従来のようにマルチシートで畝を覆うことなく、畝から雑草が生えるのを良好に抑制でき、マルチシートの除去作業を解消して農作業の労力軽減が図れ、マルチシート廃棄時の環境問題を解消するものとなる。また、上記ように畝表層部が処理された畝は、水分の蒸発が抑えられて畝の保水性が良好になり、更に、畝の下層部は固められてなく軟らかい状態が保たれているので、作物を良好に育成できる。また散布する液体は水に除草剤、凝固剤又はパルプ溶液を混合した液体であるから、水に除草剤を混合すると畝の除草効果を一層高めることができ、また凝固剤やパルプ溶液を混合すると、練土状に処理された畝表層部の乾燥後の崩壊が生じにくく、畝の崩れが抑制されて、栽培作業が良好に行える。
【0010】
又、畝表層部を練土状に処理する作業が、畝立て作業とともに行えて能率良く作業できる。
さらに、回転体18の外周面に対して液体を散布するように設けると、回転体18の外周面に付着した泥を洗い流すことができて回転体18の外周面に泥が堆積しにくくなり、処理作業を良好に継続できる利点がある。なお畝の表層部に接触して回転する前記回転体18は、回転速度が適宜変速されるよう構成されているため、適宜に速度を変更することにより、あるいは下側周面が後側から前側に移動する逆回転に切り換えることにより、異なる土質に対する処理適応性を向上できる。
【0011】
【発明の実施の形態】
以下、図面に基づき、本件発明の実施の一形態について説明する。
図1、図2に示す例は、農用トラクタ等の自走車体1の後部に、畝立て装置2と、液体散布手段及び回転体18とを備えた畝表層部処理装置13とを装着した構成のものである。
【0012】
畝立て装置2は、自走車体1の後部に装備されたリンク装置2に装着している。リンク装置2は、左右のリフトアーム3,3及びリフトロッド4,4を介して駆動昇降可能な構成としている。畝立て装置2の構成は、自走車体1のPTO軸(図示省略)からユニバーサルジョイントを経て動力が伝達される中央伝動ケース5と、中央伝動ケース5に取り付けられているフレーム6と、中央伝動ケース5から下方に延出している耕耘伝動ケース7と、耕耘伝動ケース7の下部に、耕耘軸8と耕耘爪9,…により構成されている耕耘装置10と、耕耘装置10の上方を覆う耕耘カバー11と、耕耘装置10の後側左右両側に配置している左右畝成形板12,12とを備えた構成としている。
【0013】
畝表層部処理装置13は、畝立て装置2の後方で畝表層部処理作用するように設けている。本例では、具体的には、畝立て装置2の中央伝動ケース5から左側に延出している左伝動フレーム14、左伝動フレーム14の端部から後下方に延出している左伝動ケース15、中央伝動ケース5から右側に延出している右伝動フレーム16、右伝動フレーム16の端部から後下方に延出している右伝動ケース17、左伝動ケース15及び右伝動ケース17の各下端部の左右間に回転体18を駆動回転可能に軸架している。回転体18は、その外周面が、畝立て装置2によって成形された畝上面形状に沿うような形状を有し全体としてツツミ状の形状であり、畝の中央表層部に対応する小径円筒状部18aと、該小径円筒状部18aの左右両外側に連設され畝の左右傾斜部及び左右溝部に対応する大径円筒状部18b,18bを備えた構成としている。そして、この回転体18は、中央伝動ケース5内の動力が伝動されて畝表層部に接触しながら回転し、回転体18が自走車体1によって畝に沿って移動する速度よりも大なる周速度で回転体18の下側周面が前側から後側に移動する方向に高速回転する。なお、回転体18の回転速度を適宜変速可能に構成したり、或はまた、回転体18の下側周面が後側から前側に移動する方向に逆回転させるように構成すれば、異なる土質に対する処理適応性を向上できる。
【0014】
そして、畝表層部処理装置13は、更に、液体散布手段を備えている。液体散布手段は、本例では、具体的には、自走車体1の後部に設けられている液体タンク19a、液体タンク19aからポンプ20aに液を供給する供給ホース19b、液体タンク19a内の液を圧送するポンプ20a、ポンプ20aから吐出する液を散布ノズル21,…に送る移送ホース20b、回転体18の上方に左右所定間隔を隔てて配置されていて回転体18の周面に液を散布する散布ノズル21,…を備えた構成としている。散布ノズル21,…から液体が散布される箇所は、回転体18の下端部箇所或はそれより前側位置に液体が散布されるように設けるか、又は、図示のように、回転体18の外周面に対して散布するように設ける。回転体18の下端部箇所或はそれより前側(回転体18が畝に沿って移動する方向側)位置に液体を散布されるように設けると、かなり乾燥して水分が極めて少ない土の畝に対して充分な量の液体を散布することができて良好に処理作業が行える利点がある。回転体18の外周面に対して液体を散布するように設けると、回転体18の外周面に付着した泥を洗い流すことができて回転体18の外周面に泥が堆積しにくくなり、処理作業を良好に継続できる利点がある。散布する液体は水でよいが、これに除草剤を混合しておけば、畝の除草効果を一層高めることができる。また、凝固剤やパルプ溶液を混合しておけば、練土状に処理された畝表層部の乾燥後の崩壊が生じにくく、畝の崩れが抑制されて、栽培作業が良好に行える。
【0015】
これにより、回転体18が接触する畝表層部の土が散布ノズル21,…から散布された液体で濡れた状態となり、この状態の畝表層部の土と回転体18の外周面が接触し、回転体18の外周面が畝表層部に対して接触しながら前側或は後側に移動することで、畝表層部が練土状に処理されることになる。
【0016】
上記構成のものは、例えば、以下のように作用するものとなる。機体の回転各部を回転しながら自走車体1を前進走行させると、畝立て装置2の耕耘装置10により圃場の土は耕耘され、左右畝成形板12,12により幅広の畝が形成される。そして、その畝の表層部を回転体18が接触しながら回転体18の下側周面が前側から後側に移動する方向に高速回転する。液体タンク19の液体はポンプによって送られて散布ノズル21,…から噴出して回転体18の外周面左右全幅にわたって吹き付けられる。回転体18の外周面は散布された液体で塗れた状態で畝の表層部に接触しながら高速回転するので、回転体18が接触する畝表層部の土は練土状に処理される。従って、畝立て作業を行いながら、その畝表層部の土を練土状に処理していくものとなる。このような作業が施された畝は、その表面に泥を塗ったような状態となる。従って、練土状に処理された畝表層部が乾燥すれば、泥が乾いたときのように硬くなり、畝表面が緻密で硬い土の板で畝が覆われた状態となる。
【0017】
従って、従来のようにマルチシートで畝を覆うことなく、畝から雑草が生えるのを良好に抑制でき、マルチシートの除去作業を解消して農作業の労力軽減が図れ、マルチシート廃棄時の環境問題を解消するものとなる。また、上記ように畝表層部が処理された畝は、水分の蒸発が抑えられて畝の保水性が良好になり、更に、畝の下層部は固められてなく軟らかい状態が保たれているので、作物を良好に育成できる。
【0018】
更に、上記構成としたものは、畝表層部を練土状に処理する作業が、畝立て作業とともに行えて能率よく作業でき、また、畝表層部処理装置13を畝立て装置2に対して設定高さに支持した構成であるので、畝立て装置2が成形した畝に対し畝表層部処理装置13の回転体18が畝を押し固め過ぎない程度に畝表層部に接触させて作用させることができ、畝表層部を練土状に処理し且つ下層部は押し固めない状態で処理することができる。なお、図示していないが、畝立て装置2に対する畝表層部処理装置13の回転体18の上下方向の位置を変更する回転体高さ調節機構を設けていて、土質等に応じて回転体18の畝表層部に対する接触状態を適宜上下位置変更でき、良好な処理作業が行えるようになっている。また、自走車体1に畝立て装置2を設けないで、畝表層部処理装置13のみを装着する構成とした場合は、畝表層部処理装置13による畝表層部処理作業を行うに先立って、自走車体1に畝立て装置2を装着して畝立て作業を行うことになる。
【0019】
上記のように処理された畝に対し、播種或は苗を移植する場合は、播種時或は苗移植時に硬くなった畝表層部を突き破り、硬くなっていない下層部の土に播種或は苗を移植する方法をとることになる。この方法にて播種或は苗を移植すれば、播種或は苗の移植後においても、上記のように表層部が処理された畝は上記のような効果を充分に発揮できる状態を維持できる。
【0020】
次に、図3、図4に示す例について説明する。この例は、畝表層部を練土状に処理する代りに、畝を覆う紙が散布された液体によって畝表層部の土に密着して貼り付いた状態に処理するものであり、紙26をロール状に巻いた紙ロール23を支持する紙ロール支持手段と、紙ロール23から引き出された紙26を畝上面に案内する案内手段25と、畝を被覆した紙26が畝表層部と密着させる水等の液体を散布する液体散布手段とを設けた構成の畝表層部処理装置としたものである。
【0021】
図例の具体的な構成について説明すると、図例のものは、自走車体1の後部に畝立て装置2を昇降自在に連結し、畝立て装置2の耕耘装置10の後部両側に左右畝成形板12,12を配置し、左右畝成形板12,12の後方には紙マルチ装置22を配置している。紙マルチ装置22は、耕耘カバー11のフレーム部に取り付けられている紙ロール23の支持装置24、支持装置24に巻き架けられている紙ロール23、紙ロール23から引き出した紙26を畝の表層部に案内接触する案内ローラー25、紙26の左右両端部を畝の溝部に鎮圧する左右鎮圧輪27,27、溝部の土を切削し紙26の左右両端部にかける左右回転ディスク28,28を備えた構成としている。液体散布手段は、自走車体1の後部に設けられている液体タンク19a、送液用のポンプ19b、ポンプ19bの吐出口から延出しているホース20、ホース20の終端部に取り付けられていて畝の左右全幅にわたって液体を散布するよう設けられている散布ノズル21,…、(図示省略)等により構成している。散布ノズル21,…は、紙26で覆った後の畝上に、或は、紙26で覆う前の畝上に液体を散布するように配置する。図示例では、左右回転ディスク28,28の後方に配置した構成としている。
【0022】
上記のように構成したものは、機体の回転各部を回転しながら自走車体1を走行させると、畝立て装置2の耕耘装置10により耕耘され、左右畝成形板12,12により幅広の畝が形成される。次いで、紙ロール23から紙26が引き出され、引き出された紙26は案内ローラー25により畝の表層部に接触するように案内され、紙26の左右両端部は左右鎮圧輪27,27により畝の溝部に鎮圧保持される。次いで、左右回転ディスク28,28により切削された土が紙26の左右両端部にかけられ、紙26により畝及び溝部の全幅が被覆される。次いで、被せられた紙26の全幅にわたり散布ノズル21,…から液体が散布され、紙26が畝及び溝部表面に密着する。
【0023】
従って、上記構成のものは、土壌で腐蝕しうる紙で畝を覆うことにより、畝から雑草が生えるのを良好に抑制でき、栽培終了後の除去作業の解消を解消することも可能となって農作業の労力軽減が図れ、また、紙製であることにより焼却廃棄する場合でも環境問題を回避できる。
【0024】
また、従来、畝上面を紙製マルチシートで覆うものは知られているが、紙が厚くて重いため、取り扱いが困難でコスト高となり、また、薄い紙であると破れやすいという欠点があった。しかし、上記のように処理することで、畝を覆う紙が散布された液体によって畝表層部の土に密着して貼り付いた状態になっているので、従来よりも畝から雑草が生えるのを良好に抑制でき、また、紙と畝表面との間に風が入り込んで紙が破れることが生じ難くなって、従来、単に畝上に被せるだけの紙製マルチよりも薄い紙が使用できて、資材コストを低減できる。
【0025】
なお、液体に水溶性の糊をまぜると、紙の土への接着性が高まり、紙を確実に畝の表層部に密着させることができる。また、紙が被覆された畝に対し、播種或は苗を移植する場合は、播種時或は苗移植時に紙を突き破り、紙の下側の土に播種或は苗を移植する方法をとることになる。この方法にて播種或は苗を移植すれば、播種或は苗の移植後においても、上記のように処理された畝は上記のような効果を充分に発揮できる状態を維持できる。

JP-A-6-217601 [0006]
[Problems to be solved by the invention]
In the former of the above prior art, the removal work after the cultivation is troublesome, and since the vinyl multi-film does not rot, the gas generated when incinerating it is also an environmental problem. In the latter case, the surface portion of the cocoon is compacted to reduce the collapse of the cocoon, but weeds cannot be prevented from growing like a cocoon covered with a multi-film. Therefore, the present invention does not cover the cocoon with a vinyl multi-sheet, and suppresses the growth of weeds from the cocoon, eliminates the multi-sheet removal work, reduces the labor of farm work, The problem is to solve the environmental problems.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, the present invention has taken the following technical means.
According to the first aspect of the present invention, the self-propelled vehicle body (1) is mounted with the erecting device (2), the liquid spraying means, and the rotating body (18), and is formed by the erecting device (2). The liquid spraying means for spraying liquid on the top surface of the heel while moving along the heel, and the speed at which the self-propelled vehicle body (1) moves along the heel in contact with the surface layer of the heel while moving along the heel. There is provided a rotating body (18) which is configured to rotate at a large peripheral speed and to change the speed of the rotation and to make the soil of the surface layer portion of the straw containing the liquid sprayed by the liquid spraying means kneaded. in ridge surface portion processing apparatus, the liquid spraying means, water herbicide, liquid tank mixed with coagulant or pulp solution liquid (19a), a pump (20a), a pump (20a from the liquid tank (19a) supply hose (19b) for supplying liquid to), a pump (2 liquid spray nozzle (21 discharged from a), ...) Send transfer hose (20b), the outer peripheral surface of the upward rotation is arranged at a lateral predetermined distance of the rotating body (18) (18) This is a soot surface layer processing apparatus provided with spray nozzles (21,...) For spraying liquid .
[0008]
[0009]
[Operation and effect of the invention]
According to the first aspect of the present invention, the surface layer portion of the cocoon is processed into a clay shape, so that after the treatment, the surface layer portion is dried and hardened, and the surface of the cocoon is covered with a hard earth plate. As a result, weeds can be successfully prevented from growing on the reeds without covering the reeds with a multi-sheet as in the past, eliminating the multi-sheet removal work and reducing the labor required for farm work. It will solve the problem. In addition, the soot whose surface layer portion has been treated as described above has the ability to suppress moisture evaporation and improve the water retention of the soot, and further, the lower layer portion of the soot is not hardened and is kept in a soft state. Can grow crops well. Moreover, since the liquid to be sprayed is a liquid in which a herbicide, a coagulant or a pulp solution is mixed with water, mixing the herbicide with water can further enhance the herbicidal effect of the koji, and when the coagulant and the pulp solution are mixed. In addition, the surface layer portion of the koji treated in the form of kneaded clay is less likely to collapse after drying, the kneading of the koji is suppressed, and the cultivation work can be performed satisfactorily.
[0010]
In addition, the work for treating the surface layer of the cocoon in the form of a clay can be performed together with the laying work and can be performed efficiently.
Further, if the liquid is applied to the outer peripheral surface of the rotating body 18, mud adhering to the outer peripheral surface of the rotating body 18 can be washed away, and mud does not easily accumulate on the outer peripheral surface of the rotating body 18, There is an advantage that the processing work can be continued well. Note that the rotating body 18 that rotates in contact with the surface layer portion of the kite is configured so that the rotation speed is appropriately changed, so that the lower peripheral surface is changed from the rear side to the front side by appropriately changing the speed. By switching to the reverse rotation that moves to, the process adaptability to different soil properties can be improved.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The example shown in FIG. 1 and FIG. 2 is a configuration in which the rear surface of the self-propelled vehicle body 1 such as an agricultural tractor is mounted with a vertical device 2 and a vertical surface layer processing device 13 having a liquid spraying means and a rotating body 18. belongs to.
[0012]
The erecting device 2 is attached to a link device 2 provided at the rear part of the self-propelled vehicle body 1. The link device 2 can be driven up and down via left and right lift arms 3 and 3 and lift rods 4 and 4. The structure of the erecting device 2 includes a central transmission case 5 to which power is transmitted from a PTO shaft (not shown) of the self-propelled vehicle body 1 via a universal joint, a frame 6 attached to the central transmission case 5, and a central transmission. A tilling transmission case 7 extending downward from the case 5, a tilling device 10 composed of a tilling shaft 8 and tilling claws 9,... It is set as the structure provided with the cover 11 and the left-right cocoon shaping | molding plates 12 and 12 arrange | positioned at the rear left and right both sides of the tilling apparatus 10. FIG.
[0013]
The heel surface layer processing device 13 is provided so as to perform the heel surface layer processing operation behind the heeling device 2. In this example, specifically, the left transmission frame 14 extending leftward from the central transmission case 5 of the upright device 2, the left transmission case 15 extending rearward and downward from the end of the left transmission frame 14, The right transmission frame 16 extending rightward from the central transmission case 5, the right transmission case 17 extending rearward and downward from the end of the right transmission frame 16, the left transmission case 15, and the lower end portions of the right transmission case 17 A rotating body 18 is pivoted between the left and right so as to be driven to rotate. The rotating body 18 has a shape such that the outer peripheral surface thereof conforms to the shape of the upper surface of the ridge formed by the erecting device 2 and has a generally tsumi-like shape, and a small diameter cylindrical portion corresponding to the central surface layer portion of the ridge 18a and large-diameter cylindrical portions 18b and 18b corresponding to the left and right inclined portions and the left and right groove portions of the rod, which are connected to the left and right outer sides of the small-diameter cylindrical portion 18a. Then, the rotating body 18 rotates while the power in the central transmission case 5 is transmitted and is in contact with the outer surface layer portion, and the rotating body 18 has a circumference greater than the speed at which the rotating body 18 moves along the kite by the self-propelled vehicle body 1. The lower peripheral surface of the rotating body 18 rotates at a high speed in the direction of moving from the front side to the rear side. It should be noted that if the rotational speed of the rotating body 18 can be changed as appropriate, or if the lower peripheral surface of the rotating body 18 is reversely rotated in the direction of moving from the rear side to the front side, different soil properties can be obtained. It is possible to improve the process adaptability to.
[0014]
And the soot surface layer part processing apparatus 13 is further provided with the liquid spraying means. Specifically, in this example, the liquid spraying means includes a liquid tank 19a provided at the rear part of the self-propelled vehicle body 1, a supply hose 19b for supplying liquid from the liquid tank 19a to the pump 20a, and a liquid in the liquid tank 19a. The pump 20a for pumping the liquid, the transfer hose 20b for sending the liquid discharged from the pump 20a to the spray nozzles 21,... Are arranged above the rotating body 18 with a predetermined left and right spacing, and the liquid is sprayed on the peripheral surface of the rotating body 18. It is set as the structure provided with the spraying nozzles 21 ... which do. The location where the liquid is sprayed from the spray nozzles 21,... Is provided so that the liquid is sprayed to the lower end portion of the rotator 18 or the front side position thereof, or as shown in the figure, the outer periphery of the rotator 18. Provide to spread on the surface. If the liquid is sprayed at the lower end portion of the rotating body 18 or the front side of the rotating body 18 (the direction in which the rotating body 18 moves along the fence), it will be quite dry and become a soil pot with very little moisture. On the other hand, there is an advantage that a sufficient amount of liquid can be sprayed and the processing operation can be performed satisfactorily. If the liquid is applied to the outer peripheral surface of the rotating body 18, the mud adhering to the outer peripheral surface of the rotating body 18 can be washed away, and mud does not easily accumulate on the outer peripheral surface of the rotating body 18. There is an advantage that can continue well. The liquid to be sprayed may be water, but if a herbicide is mixed therewith, the herbicidal effect of straw can be further enhanced. Moreover, if a coagulant and a pulp solution are mixed, collapse after drying of the koji surface layer part processed into the kneaded clay state will not easily occur, and the kneading of the koji will be suppressed, so that the cultivation work can be performed satisfactorily.
[0015]
Thereby, the soil of the heel surface layer part which the rotator 18 contacts becomes wet with the liquid sprayed from the spray nozzles 21,..., And the soil of the heel surface layer part in this state comes into contact with the outer peripheral surface of the rotator 18. The outer surface of the rotating body 18 moves to the front side or the rear side while being in contact with the upper surface layer portion, so that the upper surface layer portion is processed into a clay shape.
[0016]
The thing of the said structure acts as follows, for example. When the self-propelled vehicle body 1 is moved forward while rotating each part of the machine body, the soil in the field is cultivated by the cultivating device 10 of the erecting device 2, and wide ridges are formed by the left and right cocoon forming plates 12, 12. And while the rotary body 18 contacts the surface layer part of the collar, it rotates at high speed in the direction in which the lower peripheral surface of the rotary body 18 moves from the front side to the rear side. The liquid in the liquid tank 19 is sent by a pump, ejected from the spray nozzles 21,... And sprayed over the entire width of the outer peripheral surface of the rotating body 18. Since the outer peripheral surface of the rotating body 18 rotates at high speed while being in contact with the surface layer portion of the cocoon in a state of being coated with the sprayed liquid, the soil of the surface layer portion of the cocoon surface with which the rotating body 18 contacts is processed into a paste. Accordingly, the soil on the surface layer of the cocoon is processed into a clay while performing the erection work. The soot that has been subjected to such a work is in a state in which mud is applied to its surface. Therefore, when the surface layer portion of the cocoon processed into a kneaded clay is dried, it becomes hard as when the mud is dried, and the surface of the cocoon is covered with a dense and hard earth plate.

When seeding or transplanting seedlings to the cocoons treated as described above, the seedlings or seedlings that have been hardened at the time of sowing or seedling transplanting are broken through the soil of the lower layer that is not hardened. Will take a way to port. By sowing or transplanting seedlings by this method, even after sowing or transplanting seedlings, the cocoons with the surface layer treated as described above can maintain a state in which the above effects can be sufficiently exerted.
[0020]
Next, the example shown in FIGS. 3 and 4 will be described. In this example, instead of processing the surface layer of the cocoon in the form of clay, the paper covering the ridge is processed in a state of being adhered and adhered to the soil of the surface layer of the cocoon. A paper roll support means for supporting the paper roll 23 wound in a roll shape, a guide means 25 for guiding the paper 26 drawn from the paper roll 23 to the upper surface of the coffin, and the paper 26 coated with the coffin is in close contact with the surface layer portion of the coffin. This is a soot surface layer processing apparatus having a configuration in which liquid spraying means for spraying liquid such as water is provided.
[0021]
A specific configuration of the illustrated example will be described. In the illustrated example, the vertical device 2 is connected to the rear portion of the self-propelled vehicle body 1 so as to be movable up and down, and left and right vertical molding is formed on both sides of the rear portion of the tilling device 10 of the vertical device 2. The plates 12 and 12 are disposed, and a paper multi-device 22 is disposed behind the left and right saddle forming plates 12 and 12. The paper multi-device 22 is a support device 24 for a paper roll 23 attached to the frame portion of the tillage cover 11, a paper roll 23 wound around the support device 24, and a paper 26 drawn from the paper roll 23. A guide roller 25 that guides and contacts the paper, left and right pressure-reducing wheels 27 and 27 that compress the left and right ends of the paper 26 to the groove of the ridge, and left and right rotating disks 28 and 28 that cut the soil of the groove and apply it to the left and right ends of the paper 26. It has a configuration with. The liquid spraying means is attached to a liquid tank 19a provided at the rear part of the self-propelled vehicle body 1, a pump 19b for feeding liquid, a hose 20 extending from the discharge port of the pump 19b, and a terminal part of the hose 20. It is constituted by spray nozzles 21,... (Not shown) provided so as to spray the liquid over the entire left and right width of the basket. The spray nozzles 21,... Are arranged so as to spray the liquid on the bottle after being covered with the paper 26 or on the bottle before being covered with the paper 26. In the illustrated example, it is configured to be arranged behind the left and right rotating disks 28, 28.
[0022]
In the above configuration, when the self-propelled vehicle body 1 travels while rotating each part of the airframe, it is cultivated by the cultivating device 10 of the erecting device 2, and wide ridges are formed by the left and right ridge forming plates 12, 12. It is formed. Next, the paper 26 is pulled out from the paper roll 23, the drawn paper 26 is guided by the guide roller 25 so as to come into contact with the surface layer portion of the bag, and the left and right ends of the paper 26 are pressed by the left and right pressure-reducing wheels 27, 27. Suppressed and held in the groove. Next, the soil cut by the left and right rotating disks 28 and 28 is applied to the left and right ends of the paper 26, and the paper 26 covers the entire width of the ridges and grooves. Next, the liquid is sprayed from the spray nozzles 21,... Over the entire width of the covered paper 26, and the paper 26 comes into close contact with the ridges and the groove surface.
[0023]
Therefore, the thing of the said structure can suppress well the growth of a weed from a cocoon by covering a cocoon with the paper which can be corroded in soil, and it also becomes possible to eliminate the cancellation | elimination of the removal work after completion | finish of cultivation. The labor of farming can be reduced, and environmental problems can be avoided even when incinerated by using paper.
[0024]
Conventionally, a paper multi-sheet covering the top surface of the paper is known. However, since the paper is thick and heavy, it is difficult to handle and expensive, and the thin paper is easily broken. . However, by treating as described above, the paper covering the reeds is in a state of sticking to the soil on the surface layer of the reeds, so that weeds can grow from the reeds more than before. It is possible to suppress well, and it is difficult for the paper to break due to wind entering between the paper and the surface of the paper, and conventionally, a paper that is thinner than a paper mulch that can be simply put on the paper can be used, Material costs can be reduced.
[0025]
In addition, when water-soluble glue is mixed in the liquid, the adhesiveness of the paper to the soil is increased, and the paper can be securely adhered to the surface layer portion of the ridge. Also, when seeding or transplanting seedlings to paper-coated cocoons, the method must be used to break through the paper at the time of sowing or seedling transplanting and sow or transplant seedlings to the soil below the paper. become. By sowing or transplanting seedlings by this method, even after sowing or transplanting seedlings, the cocoons treated as described above can maintain a state where the above effects can be sufficiently exerted.
