Description

【０００１】
【発明の属する技術分野】
本発明は、苗箱に苗を作り、田植機で田植えをする、従来の水稲育成システムとは根本的に異なり、刈取を行なった後の水田に乾田のままで水稲の種子を直接に播種する乾田直播の新たな方法と装置を提供するものである。
【０００２】
【従来の技術】
従来から乾田直播方法と装置は存在した。従来の方法は、図５に示す如く、乾田の土壌面に播種溝Ｄを掘削し、該播種溝Ｄの上に種子Ｓを播種し、その上に、播種溝Ｄを掘削した際に出た土壌を覆土Ｅとしていたのである。
【０００３】
【発明が解決しようとする課題】
しかし、該従来の乾田直播方法と装置の場合には、雨が強く降った場合には乾田の表面に水溜まりができて、この水溜まりに種子Ｓが浸漬した状態となり、空気不足の状態となり、発芽する前に腐ってしまうという不具合があったのである。
また、種子Ｓの上に掘削土壌を被覆するのであるが、該被覆土壌が完全に行なわれない場合や、被覆土壌に大きな土塊が多い場合や、稲の刈り株の直ぐ横に播種した場合には、雑草の種子の発芽を被覆した土壌で抑えるということができず、水稲の種子Ｓの直ぐに近傍の位置から、雑草種子が発芽し、雑草の多い水田となってしまうのである。
本発明は、このような従来技術の不具合を解消するものである。
【０００４】
【課題を解決するための手段】
本発明が解決しようとする課題は以上の如くであり、次に該課題を解決するための手段を説明する。
【０００５】
トラクタ（Ｔ）の後部にロータリ耕耘装置（Ｒ）を昇降自在に装着し、該ロータリ耕耘装置（Ｒ）の後部に施肥・播種装置を装着した乾田直播装置において、該ロータリ耕耘装置（Ｒ）は、爪軸（１）に、なた爪（３）と直刀（２）と溝掘爪（４）を装着し、該なた爪（３）により、乾田土壌面を１〜３ｃｍの深さで全面を耕耘して耕耘砕土層（Ｂ）を掘削し、該直刀（２）により、深さが土壌表面から５〜７ｃｍで幅が１〜２ｃｍの播種溝（Ａ）を、播種する条の位置に掘削し、該溝掘爪（４）により、深さ１２〜１５ｃｍで幅５〜７ｃｍ程度の排水溝（Ｃ）を、播種溝（Ａ）の５〜６条毎に掘削すべく構成し、前記施肥・播種装置は、種子ホッパー（１６）と肥料ホッパー（９）を配置し、該種子ホッパー（１６）と肥料ホッパー（９）の下部に、播種施肥繰出機構（１５）を配置し、前記施肥・播種装置の先端で、ロータリ耕耘装置（Ｒ）の直後の位置には播種溝掘削ディスク（５）を配置し、該播種溝掘削ディスク（５）の進行と共に溝を、直刀（２）により掘削した播種溝（Ａ）の上に、更に掘削すべく構成し、該播種溝掘削ディスク（５）の２枚のディスクの間に、播種施肥繰出機構（１５）から連通した播種パイプ（１２）が連通して、種子（Ｓ）を播種溝（Ａ）の中に落下させ、該播種溝（Ａ）の中の土壌表面から３〜５ｃｍの深さに播種すべく構成し、前記播種溝掘削ディスク（５）と播種パイプ（１２）の後部で、横に偏心した位置に、施肥ディスク（６）を配置し、該施肥ディスク（６）の後部に施肥パイプ（１１）を連通し、肥料ホッパー（９）から繰り出された肥料粒を落下し、該播種溝掘削ディスク（５）と播種パイプ（１２）と、施肥ディスク（６）と施肥パイプ（１１）の後部に、覆土ディスク（７）を配置し、該覆土ディスク（７）の後部に、鎮圧ローラー（８）を配置したものである。
【０００６】
【発明の実施の形態】
次に本発明の実施の形態を説明する。
図１は本発明の乾田直播装置をトラクタＴの後部に装着した状態の前方斜視図、図２は同じく乾田直播装置をトラクタＴに装着した状態の後方斜視図、図３はロータリ耕耘装置Ｒの爪軸１に直刀２となた爪３と溝掘爪４を装着した状態の後面図、図４は本発明の乾田直播方法と装置による播種後の状態を示す断面図、図５は従来の乾田直播方法と装置による播種後の状態を示す断面図である。
【０００７】
図１と図２において、トラクタＴの後部に本発明の乾田直播装置を装着した状態について説明する。
トラクタＴの後部に設けた作業機装着装置に、ロータリ耕耘装置Ｒを昇降自在に装着する。該ロータリ耕耘装置Ｒの後部に乾田直播装置を装着するのである。 該乾田直播装置はロータリ耕耘装置Ｒと共に、トラクタＴの油圧装置により昇降自在とされている。
【０００８】
ロータリ耕耘装置Ｒは、図３に示す如く、爪軸１に、直刀２となた爪３と溝掘爪４の３種類の爪が装着されており、なた爪３により耕耘砕土層Ｂを掘削し、直刀２により播種溝Ａを掘削し、溝掘爪４により排水溝Ｃを掘削すべく構成している。
【０００９】
該耕耘砕土層Ｂと播種溝Ａと排水溝Ｃの構成は、図４に示す如く、乾田土壌面を１〜３ｃｍの厚さｍで全面を耕耘して耕耘砕土層Ｂとしている。また、播種する条の位置には、土壌表面から５〜７ｃｍの深さａで、幅が１〜２ｃｍの播種溝Ａを構成している。
また、播種された種子Ｓは、前記播種溝Ａの中の土壌表面から３〜５ｃｍの深さに播種されている。また、播種溝Ａの５〜６条毎に、深さｂが１２〜１５ｃｍで幅５〜７ｃｍ程度の排水溝Ｃを穿設しているのである。
【００１０】
次に、乾田直播装置の施肥・播種装置について説明する。
上部に、種子ホッパー１６と肥料ホッパー９を一体的にして配置している。該種子ホッパー１６と肥料ホッパー９の株に、種子繰出装置と施肥繰出装置の２つの繰出装置を一体的とした播種施肥繰出機構１５が配置されている。該播種施肥繰出機構１５は駆動モーター１０により電気的に駆動されている。
【００１１】
施肥・播種装置の先端で、ロータリ耕耘装置Ｒの直後の位置には、播種溝掘削ディスク５が配置されている。該播種溝掘削ディスク５は２枚のディスクを楔状に配置して、先端を閉じた側として、進行と共に溝を、直刀２により掘削した播種溝Ａの上に掘削すべく構成している。直刀２により一旦播種溝Ａを構成しているが、該播種溝Ａはなた爪３や溝掘爪４と共に掘削するので、播種溝Ａは一旦埋まってしまうのである。故に播種溝掘削ディスク５により再度播種溝Ａを作り直す必要があるのである。該播種溝掘削ディスク５の２枚のディスクの間に、播種施肥繰出機構１５から連通した播種パイプ１２が連通して、種子Ｓを播種溝掘削ディスク５により構成した播種溝Ａの中に落下させている。
【００１２】
また播種溝掘削ディスク５と播種パイプ１２の後部で、僅かに横に偏心した位置に、施肥ディスク６が配置されており、該施肥ディスク６の後部に施肥パイプ１１が連通されている。該施肥パイプ１１からは、播種施肥繰出機構１５の部分で肥料ホッパー９から繰り出された一定量の肥料粒が落下させられる。
【００１３】
該播種溝掘削ディスク５と播種パイプ１２と、施肥ディスク６と施肥パイプ１１の後部に、覆土ディスク７が配置されている。そして、覆土ディスク７の後部には、１０条分がすべて連通された鎮圧ローラー８が配置されている。播種溝掘削ディスク５と施肥ディスク６と覆土ディスク７と播種施肥繰出機構１５とホッパー１６・９等は、１条ずつが単位として構成されており、それぞれを取外し可能としているが、ロータリ耕耘装置Ｒと鎮圧ローラー８は、全ての条（１０条）に渡り、１台ずつが設けられている。
【００１４】
次に、図３において、ロータリ耕耘装置Ｒの構成を説明する。
該図３に示した実施例のロータリ耕耘装置Ｒにおいては、１０条分の播種と施肥を一度に行なうことができるように耕耘・掘削可能な構成としている。そして左端部と中央部に、排水溝Ｃを構成する為の溝掘爪４・４が植設されている。左右の溝掘爪４・４の間には、５本ずつの爪軸１が配置されており、それぞれが５条ずつ、合計１０条の播種溝Ａを掘削する。そして、該播種溝Ａの内部に、播種を行ない、近傍に施肥を行なうのである
【００１５】
そして、それぞれの直刀２・２の間には、なた爪３が配置されており、この間の部分は、耕耘砕土層Ｂを掘削すべく構成している。該耕耘砕土層Ｂの１〜３ｃｍの厚さｍは、雑草の発芽を防ぐ為に必要な最適な層の厚さとしている。またこの厚さであれば、空気層から種子Ｓに対して酸素が供給されるので、種子Ｓの発芽にも好適な影響を与えるのである。
【００１６】
次に、図４において、播種・施肥の直後の状態を説明する。
５条ずつの左右には、土壌表面から１２〜１５ｃｍの深さｂの排水溝Ｃが設けられている。この排水溝Ｃが設けられていることにより、強い雨が降った場合にも、耕耘砕土層Ｂや播種溝Ａの部分に水溜まりが発生することなく、種子Ｓが発芽する前に腐るということが無くなるのである。また、種子Ｓは播種溝Ａの内部に播種することとなるので、もし強い雨が降った場合にも、流れる雨水により種子Ｓが排水溝Ｃの方向に移動してしまうということも無いのである。
【００１７】
【発明の効果】
本発明は、以上の如く構成したので、次のような効果を奏するのである。
第一に、トラクタＴの後部にロータリ耕耘装置Ｒを昇降自在に装着し、該ロータリ耕耘装置Ｒの後部に施肥・播種装置を装着した乾田直播装置において、該ロータリ耕耘装置Ｒは、爪軸１に、なた爪３と直刀２と溝掘爪４を装着し、該なた爪３により、乾田土壌面を１〜３ｃｍの深さで全面を耕耘して耕耘砕土層Ｂを掘削し、該直刀２により、深さが土壌表面から５〜７ｃｍで幅が１〜２ｃｍの播種溝Ａを、播種する条の位置に掘削し、該溝掘爪４により、深さ１２〜１５ｃｍで幅５〜７ｃｍ程度の排水溝Ｃを、播種溝Ａの５〜６条毎に掘削すべく構成し、前記施肥・播種装置は、種子ホッパー１６と肥料ホッパー９を配置し、該種子ホッパー１６と肥料ホッパー９の下部に、播種施肥繰出機構１５を配置し、前記施肥・播種装置の先端で、ロータリ耕耘装置Ｒの直後の位置には播種溝掘削ディスク５を配置し、該播種溝掘削ディスク５の進行と共に溝を、直刀２により掘削した播種溝Ａの上に、更に掘削すべく構成し、該播種溝掘削ディスク５の２枚のディスクの間に、播種施肥繰出機構１５から連通した播種パイプ１２が連通して、種子Ｓを播種溝Ａの中に落下させ、該播種溝Ａの中の土壌表面から３〜５ｃｍの深さに播種すべく構成したので、乾田土壌面を全面を１〜３ｃｍの厚さｍに浅く耕耘した耕耘砕土層Ｂを構成しているので、この部分が雑草の種子を被覆し、雑草の発芽を抑えることができて、除草効果を発揮する乾田直播装置を構成することができたのである。
【００１８】
また、播種パイプ１２からの種子Ｓの落下位置には、狭く深い播種溝Ａを構成しているので、播種深さである３〜５ｃｍを確保することができ、該播種溝Ａの下部に溜まった雨水を発芽用の水分として供給することができるので、土壌が乾いた場合にも、発芽率を低下させることが少ないのである。播種溝Ａの５〜６条置きに、排水溝Ｃを設けたことにより、強い雨が降った場合のような、余分な水分を排水することかできるので、水分過多による発芽率の低下を抑えることができる乾田直播装置とすることができたのである。
【００１９】
第二に、請求項１記載の乾田直播装置において、前記播種溝掘削ディスク５と播種パイプ１２の後部で、横に偏心した位置に、施肥ディスク６を配置し、該施肥ディスク６の後部に施肥パイプ１１を連通し、肥料ホッパー９から繰り出された肥料粒を落下し、該播種溝掘削ディスク５と播種パイプ１２と、施肥ディスク６と施肥パイプ１１の後部に、覆土ディスク７を配置し、該覆土ディスク７の後部に、鎮圧ローラー８を配置したので、該播種溝Ａの内部に、播種を行ない、近傍に施肥を行なうことが可能となったのである。
また、多数条分の播種と施肥を一度に行なうことができるように乾田直播装置を構成とすることができたものである。

A new method and apparatus for dry rice seeding is provided.
[0002]
[Prior art]
There has been a dry paddy direct sowing method and apparatus. As shown in FIG. 5, the conventional method was excavated with the sowing groove D on the soil surface of the dry paddy, sowing the seed S on the sowing groove D, and emerged when the sowing groove D was excavated thereon. The soil was covered with soil E.
[0003]
[Problems to be solved by the invention]
However, in the case of the conventional dry paddy direct sowing method and apparatus, when rain falls strongly, a puddle is formed on the surface of the dry paddy, and the seed S is immersed in the puddle, resulting in a lack of air and germination. There was a problem that it would rot before it was done.
In addition, the excavated soil is covered on the seeds S. When the covered soil is not completely formed, when the covered soil has a large mass of soil, or when the seed S is sown right next to the rice stubble. It cannot be said that the germination of weed seeds is suppressed by the soil covered with it, and the weed seeds germinate from a position immediately adjacent to the seed S of the paddy rice, resulting in a paddy field with many weeds.
The present invention solves such problems of the prior art.
[0004]

FIG. 4 is a sectional view showing a state after sowing by the dry rice direct sowing method and apparatus of the present invention, and FIG. 5 is a conventional view. It is sectional drawing which shows the state after sowing by the dry rice direct sowing method and apparatus.
[0007]
1 and 2, a state in which the dry seeding device of the present invention is attached to the rear part of the tractor T will be described.
A rotary tiller R is mounted on a work implement mounting device provided at the rear of the tractor T so as to be movable up and down. A dry rice seeding device is attached to the rear of the rotary tiller R. The dry paddy direct sowing device can be moved up and down by the hydraulic power device of the tractor T together with the rotary tiller R.

[0009]
As shown in FIG. 4, the tilled ground layer B, the sowing groove A, and the drainage groove C have a dry paddy soil surface that is 1 to 3 cm thick and is plowed all over to form a tilled ground layer B. In addition, a seeding groove A having a depth a of 5 to 7 cm and a width of 1 to 2 cm is formed at the position of the strip to be seeded.
The seed S sowed is sown at a depth of 3 to 5 cm from the soil surface in the sowing groove A. Moreover, the drainage groove | channel C whose depth b is 12-15 cm and width | variety is about 5-7 cm is drilled for every 5-6 articles | strains of the seeding groove | channel A.
[0010]
Next, the fertilization and sowing apparatus of the dry rice direct sowing apparatus will be described.
In the upper part, the seed hopper 16 and the fertilizer hopper 9 are integrally arranged. The seed hopper 16 and the fertilizer hopper 9 are provided with a sowing and fertilizer feeding mechanism 15 in which two feeding devices of a seed feeding device and a fertilizer feeding device are integrated. The sowing and fertilizer feeding mechanism 15 is electrically driven by a drive motor 10.
[0011]
A seeding groove excavation disk 5 is disposed at a position immediately after the rotary tiller R at the tip of the fertilizer application and seeding device. The sowing groove excavation disk 5 is configured so that two disks are arranged in a wedge shape, and the groove is excavated on the sowing groove A excavated by the straight blade 2 with the front end closed. Although the sowing groove A is once constituted by the straight blade 2, since the sowing groove A is excavated together with the nail claw 3 and the groove claw 4, the sowing groove A is once buried. Therefore, it is necessary to recreate the sowing groove A by the sowing groove excavating disk 5. The sowing pipe 12 communicated from the sowing and fertilizer feeding mechanism 15 communicates between the two disks of the sowing groove excavation disk 5, and the seed S is dropped into the sowing groove A constituted by the sowing groove excavation disk 5. ing.
[0012]
Further, a fertilization disk 6 is arranged at a position slightly decentered laterally at the rear part of the sowing groove excavation disk 5 and the sowing pipe 12, and the fertilization pipe 11 is communicated with the rear part of the fertilization disk 6. From the fertilizer application pipe 11, a certain amount of fertilizer grains fed out from the fertilizer hopper 9 at the portion of the sowing fertilizer feed-out mechanism 15 is dropped.
[0013]
A soil covering disk 7 is disposed at the rear of the sowing groove excavation disk 5, the sowing pipe 12, the fertilization disk 6 and the fertilization pipe 11. Then, a pressure reducing roller 8 in which all 10 strips are communicated is disposed at the rear portion of the soil covering disk 7. The sowing groove excavating disk 5, fertilizing disk 6, covering soil disk 7, sowing fertilizer feeding mechanism 15, hoppers 16, 9 and the like are configured as one unit, and each can be removed. And the pressure-reducing roller 8 is provided one by one over all the articles (10 articles).
[0014]
Next, in FIG. 3, the structure of the rotary tiller R will be described.
The rotary tiller R of the embodiment shown in FIG. 3 is configured to be able to be cultivated and excavated so that seeding and fertilization for 10 strips can be performed at a time. Groove claws 4 and 4 for constructing drainage grooves C are planted at the left end and the center. Five claw shafts 1 are arranged between the left and right groove claw 4, 4, and each of the five claw shafts 1 excavates a total of 10 sowing grooves A. Then, sowing is performed in the sowing groove A, and fertilization is performed in the vicinity.
And the nail | claw 3 is arrange | positioned between each straight sword 2 * 2, and the part between these is comprised in order to excavate the cultivation ground layer B. A thickness m of 1 to 3 cm of the tilled ground layer B is an optimum layer thickness necessary for preventing weed germination. Moreover, since oxygen will be supplied with respect to the seed S from an air layer if it is this thickness, it will have a suitable influence also on the germination of the seed S.
[0016]
Next, in FIG. 4, the state immediately after sowing and fertilization will be described.
On the left and right sides of the five strips, drainage grooves C having a depth b of 12 to 15 cm from the soil surface are provided. Since the drainage groove C is provided, even when heavy rain falls, the seed S does not stagnate before the seed S germinates without causing a puddle in the tilled soil layer B or the sowing groove A. It disappears. In addition, since the seed S is sown inside the sowing groove A, the seed S does not move in the direction of the drainage groove C due to the flowing rainwater even if heavy rain falls. .
[0017]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
First, in a dry rice direct sowing apparatus in which a rotary tiller R is mounted on the rear part of the tractor T so as to be movable up and down, and a fertilizer and seeding apparatus is mounted on the rear part of the rotary tiller R, the rotary tiller R has a claw shaft 1. In addition, the nail claw 3, the straight blade 2 and the groove claw 4 are attached, and the claw crushing soil layer B is excavated by cultivating the entire surface of the dry paddy soil with a depth of 1 to 3 cm with the claw claw 3. With the straight blade 2, a sowing groove A having a depth of 5 to 7 cm and a width of 1 to 2 cm from the soil surface is excavated at the position of the seed to be sowed, and the groove nail 4 has a depth of 12 to 15 cm A drainage groove C of about 5 to 7 cm is configured to be excavated every 5 to 6 of the sowing groove A, and the fertilizer and sowing apparatus includes a seed hopper 16 and a fertilizer hopper 9, and the seed hopper 16 and the fertilizer At the bottom of the hopper 9, a sowing and fertilizing feeding mechanism 15 is arranged, and at the tip of the fertilizing and sowing device, A sowing groove excavation disk 5 is arranged at a position immediately after the cultivating device R, and the groove is configured to be further excavated on the sowing groove A excavated by the straight blade 2 as the sowing groove excavation disk 5 advances. The sowing pipe 12 communicated from the sowing fertilizer feeding mechanism 15 communicates between the two disks of the sowing groove excavation disk 5 to drop the seed S into the sowing groove A, Since it is configured to sow at a depth of 3-5 cm from the soil surface of the soil, it constitutes a cultivated crushed soil layer B in which the entire surface of the dry paddy soil is shallowly cultivated to a thickness m of 1-3 cm. The seedling of the rice field was able to be suppressed, and germination of weeds could be suppressed, and a dry paddy direct sowing apparatus that exhibited a herbicidal effect could be constructed .
[0018]
Further, a narrow and deep sowing groove A is formed at the position where the seed S falls from the sowing pipe 12, so that a seeding depth of 3 to 5 cm can be secured, and the seed S is accumulated in the lower part of the sowing groove A. Since rainwater can be supplied as moisture for germination, the germination rate is hardly reduced even when the soil is dry. Since the drainage groove C is provided in every 5-6 rows of the sowing groove A, excess water can be drained as in the case of heavy rain, so the reduction in germination rate due to excessive moisture is suppressed. It was possible to make a dry rice field direct sowing device .
[0019]
Secondly, in the dry paddy direct sowing apparatus according to claim 1, a fertilization disk 6 is arranged at a position laterally decentered at the rear part of the sowing groove excavation disk 5 and the sowing pipe 12, and fertilization is performed at the rear part of the fertilization disk 6. The pipe 11 is communicated, the fertilizer grains fed out from the fertilizer hopper 9 are dropped, and the sowing groove excavation disk 5, the sowing pipe 12, the fertilization disk 6, and the fertilization pipe 11 are arranged at the rear of the soil covering disk 7, Since the pressure reducing roller 8 is disposed at the rear part of the soil covering disk 7, seeding is performed in the seeding groove A and fertilization can be performed in the vicinity.
Moreover, the dry rice field direct sowing apparatus was able to be configured so that sowing and fertilization of a large number of strips could be performed at a time.
