Description

【0001】
【発明の属する技術分野】
本発明は、播種機に関するもので、農業機械の技術分野に属する。
【0002】
【従来の技術】
水稲の湛水直播栽培に使用する播種機は、種子タンク内の種子を繰り出す繰出装置が設けられ、その繰出装置に複数の移送管と播種管とを連通して構成されている。そして、播種機は、繰出装置から繰り出された種子を、エアチャンバ−から吹き出してくる圧縮空気によって、前記移送管内を播種管まで空気搬送し、圃場面に播種する構成としている。
【0003】
【発明が解決しようとする課題】
従来、湛水直播による水稲の栽培は、播種後そのまま水を溜めて発芽、育苗するのが慣行であった。この育苗方法は、湛水の保温効果によって、寒さに弱い幼苗を寒さから護り、健苗として育苗することができると知られていた。
ところが、近年、播種後落水して土壌を酸化状態におく方が、出芽、育苗により効果的であることが発表されている。試験結果によると、播種後の土壌は、亀裂が入るくらい強く乾かした方が、成育後の倒伏防止や、鳥害を少なくすることに役立つと発表されている。
【0004】
しかしながら、従来の播種機は、湛水直播しか考慮しておらず、播種後の圃場から迅速に排水(落水)や湛水を繰り返すことは困難で、排水や湛水に長時間要する課題があった。
【0005】
【課題を解決するための手段】
本発明は、上述した課題を解決するために、次の如き技術手段を講ずるものである。すなわち、操舵用の前輪(10,10’)と推進用の後輪(11、11’)とを備える走行車体(1)を設け、種子タンク(5)内の種子を繰出装置(6)で移送管(7)へ繰り出し、起風翼車(8)によって起風された圧縮空気が貯留されるエアチャンバ(9)から吹き込まれてくる圧風によって種子が前記移送管(7)内で搬送されて播種管(2a,2b)へ達する構成とし、前記播種管(2a,2b)により走行車体(1)の前進に伴って圃場面に8条に播種する播種機において、前記播種管(2a,2b)を表土を均しながら滑動するフロート(24)に取り付け、前記播種管(2a,2b)の後方に角度変更可能な覆土板(25)を各々設けると共に、圃場面に溝を形成する作溝器(3)を走行車体(1)の後輪(11、11’)の後方で且つ前記フロート(24)の間に位置にさせて機枠(28)に着脱可能に設け、前記作溝器(3)を取り外してその取り外した部分の機枠(2 8)にレーキ(35)を取り付けできる構成とした播種機としたものである。
【0006】
【発明の効果】
本発明は、以上のように構成されているから、排水性の悪い圃場では、作溝器(3)を取り付けて播種作業を行うことにより、前記作溝器(3)が後輪(11、11’)の通過跡に排水溝を作溝するため比較的小さい土壌抵抗で作溝でき、圃場面には、播種作業に伴って播種条の側方に沿わせて溝(排水溝)を同時に形成することができる。したがって、播種後の排水や湛水をきわめて容易に行なうことが可能であり、しかも、短時間に行なうことができる効果を有する。また、排水性の良い圃場では、作溝器(3)を取り外してその取り外した部分の機枠(28)にレーキ(35)を取り付けて播種作業を行うことにより、前進に伴って後輪(11、11’)の車輪跡を均平に均し、圃場の均平精度を高めることができる。
【0007】
【発明の実施の形態】
以下、本発明の実施の形態を説明する。
まず、播種機は、図2乃至図5に示すように、種子タンク5、繰出装置6、移送管7、播種管2a、2b、その他、起風翼車8やエアチャンバ9等の付属装置から構成し、走行車体1の後部に装着して湛水直播機としている。
【0008】
そして、走行車体1は、操舵用の前輪10、10’と推進用の後輪11、11’とを設け、中央のエンジンル−ム12上に操縦座席13を配置して設け、水田の耕盤上を回転しながら走行できる構成としている。そして、昇降リンク14は、上下一対の平行リンクからなり、前部が前記走行車体1の後部機枠15に枢着連結し、後部に連結用のヒッチ16を取り付け、車体1側の油圧シリンダ17によって昇降する構成としている。そして、前記ヒッチ16には、以下具体的に説明する播種機を取り付けて支持し、上下昇降自由に構成している。
【0009】
つぎに、播種機の構成を、図面に基づいて具体的に述べる。
まず、繰出装置6は、図4および図5に示すように、外周に多数の種子溝18を形成した繰り出しロ−ル19を種子タンク5の下側に臨ませて伝動可能に軸架して設け、その下方には種子を搬送する移送管7の始端部を臨ませて設けた構成としている。なお、種子溝18は、図5に示すように、側部の調節具20を回転調節輪21の回転調節操作によって軸に沿わせて左右に摺動し、種子の貯留容積を大小調節できる構成としている。22は入力スプロケットである。
【0010】
そして、ブラシ23は、前記した繰り出しロ−ル19の表面に接触して均す働きをして、種子溝18の種子量を均一にするために設けている。
そして、種子タンク5は、図2および図3に示すように、走行車体1の後部に連結した播種機の構成部材の一つとして搭載している。
つぎに、エアチャンバ9は、図4および図5に示すように、円筒形状で前記繰出装置6の下側の後に横向きに配置して設け、一端に起風翼車8を連結し、他端を蓋で密封して起風された空気を貯留できる構成としている。そして、移送管7は、その搬送始端部を開口して前記エアチャンバ9に連通して設け、高圧状態で貯留した空気(送風)が送り込まれ、前述のように上方から供給されてくる所定量の種子を空気搬送するように構成している。
【0011】
このようにして、移送管7は、その始端部をエアチャンバ9に連通し、終端部側を圃場面に近い側に向けて延長し、播種位置に設けている播種管2a、2bにそれぞれ連通して構成している。そして、播種管2a、2bは、接地面に設けて表土を均しながら滑動するフロ−ト24に取り付け、前進に伴って整地された圃場面に噴出、播種する構成としている。
【0012】
そして、覆土板25は、図1に示すように、前述した播種管2a、2bを設けている播種条の後方にそれぞれ配置して設け、連杆26と操作ワイヤ−27とを介して覆土可能角度と覆土しない角度とに変更調節できる構成としている。
つぎに、作溝器3は、図1に示すように、前記フロ−ト24の間に位置させて前側上方に横向きに設けている機枠28に取り付けて設け、走行車体1の前進に伴って圃場面に排水溝を形成するように構成している。そして、作溝器3は、図1に示す実施例の場合、後輪11、11’の通過した車輪跡を追うように進行して排水溝を形成する関係位置に構成している。
【0013】
そして、作溝器3と前記播種管2とは、これらが通過した後に、播種条の側方に沿わせて略平行に排水溝を形成する関係位置に配置して構成すれば良く、取付け位置の前後関係は自由に選択すれば良い。
なお、図3において、29は肥料タンク、30は肥料移送管、31は施肥管を示す。
【0014】
このように構成した播種機を、整地作業が終わって湛水状態にした圃場に入れて肥料タンク29に肥料を充填し、種子タンク5には種子を充填して前進させて播種作業を開始する。
すると、種子タンク5内の種子は、図4に示すように、下方の回転している繰り出しロ−ル19に達し、繰り出しロ−ル19の外周の種子溝18にそれぞれ供給されて溜り回転方向に送られる。そのとき、種子溝18内の種子は、回転下手側にあるブラシ23に達して表面が均平に均されて定量となり、繰り出しロ−ル19の回転に伴って下方の移送管7の搬送始端部に落下する。そのとき、エアチャンバ9は、起風翼車8によって起風された圧縮空気が貯留されており、連通している各移送管7に流入することになる。
【0015】
このようにして、種子は、エアチャンバ9から吹き込まれてくる圧風によって移送管7内を空気搬送されて先端側の播種管2a、2bに達し、フロ−ト24によって整地された後の圃場に噴出、播種される。そして、覆土板25は、進行方向に対して所定の角度を保ち表土を掻き寄せ、種子が播かれている播種溝の上に覆土を行い、播種作業を完了する。
【0016】
このようにして播種機は、走行車体1の前進に伴って湛水した圃場面に播種作業を行なうが、同時に、機枠28に取り付けられている作溝器3が、播種管2によって播種される播種条の側方に沿って略平行状に排水溝を作溝しながら前進している。この場合、作溝器3は、後輪11、11’の通過した跡上を前進しながら排水溝を作溝していくから比較的土壌抵抗が小さく、少ない消費馬力によって作溝することができる。
【0017】
以上述べたように、播種機によって播種作業と同時に作溝した溝は、一端部を圃場における水の取入れ口に、他端部を圃場の排水口にそれぞれ鍬等で溝切りをして水が流れ易いように接続し、入水、排水が容易にできるように事後処理を行なうことが肝要である。一般的に、水田は、土壌表面を充分均平に均すことが最低の必要条件であるが、広い圃場では部分的に低い場所ができて水が停滞することがあり、その場所では苗立ち不良になるおそれがある。
【0018】
また、圃場は、土壌表面の均平精度が高くなればなるほど、水の移動が遅くなる傾向があり、湛水や排水に時間がかかることが経験上知られている。
このように、本発明は、実施例で説明したように構成することによって、播種と同時に溝を作溝して排水、入水を迅速に行なうことができる特有の効果を有するものである。
【0019】
そもそも圃場に水を溜める理由は、水の保温効果を利用して幼苗を寒さから護るためであるが、種子は、寒さに強く、播種から発芽までの期間は水による保温の必要性がないことが解っている。むしろ、播種後の圃場は、排水によって土壌に亀裂が入るくらいまで乾かして酸化の状態にする方が、発芽とその後の生育に良いといわれている。そして、圃場は、発芽が完了して育苗の行程に移ると、幼苗を寒さから護るために湛水が必要になり、水を溜めて保温効果を期待することになる。
【0020】
以上のような播種、発芽、育苗の過程において、本発明は、圃場の排水と湛水とを繰り返すとき、播種と同時に作溝した排水溝が効果を発揮し、水の移動を助けて迅速に排水、湛水を行なうことができる。
【0021】
別実施例1
つぎに、別実施例1を図6に基づいて説明する。
図6に示す別実施例1は、作溝器3に代えてレ−キ35を着脱自由に取り付けて構成したものである。すなわち、別実施例1は、作溝器3とレ−キ35とを圃場の水はけ状態に応じて選択して機枠28に付替えながら播種作業を行なうことができる構成としたものである。
【0022】
このように、別実施例1は、排水性の良い圃場では、図6に示すように、作溝器3を取り外してその部分の機枠28にレ−キ35を取り付けて播種作業を行なう。すると、レ−キ35は、前進に伴って後輪11、11’の車輪跡を均平に均しながら消して圃場の均平精度を高めることができる。また、排水性の悪い圃場では、作溝器3に付替えて(図1参照)播種作業を行なうことによって排水溝を形成し、排水、湛水に際して水の移動を迅速に行なうことができる。
【0023】
別実施例2
つぎに、別実施例2を図7乃至図9に基づいて説明する。
別実施例2は、灌水直播に使用する8条播種機の条止めに関する構成である。
従来から広く知られているように、多条播きの播種機は、田植機と同様に播種行程の最終播種条の一つ前で条止めを行い、最終行程に全条(別実施例2は8条)播種ができるように作業することを慣行としている。
【0024】
まず、クラッチレバ−40は、種子の繰り出しロ−ル19(図4参照)のクラッチ装置41を断続操作するシフタ−42に操作ワイヤ−43によって連結し、動力の断続操作ができる構成としている。そして、クラッチレバ−40は、操作ワイヤ−44を連杆26に連結して、覆土板25の角度を変更可能に連結して構成している。そして、クラッチレバ−40は、繰り出しロ−ル19のクラッチ装置41を切り操作すると、その播種管2a、2bの後方にある覆土板25が連動されて回動し、覆土ができない角度に変更調節される構成としている。
【0025】
そして、クラッチレバ−40は、図7において、実線に位置がクラッチ装置41が伝動状態にあり、覆土板25が、図9の実線の位置にあって覆土作用ができる位置にある。つぎに、クラッチレバ−40は、図7において、仮想線に位置に操作すると、クラッチ装置41が切り位置となって繰り出しロ−ル19が停止し、覆土板25が、図9の仮想線の位置に調節され覆土作用ができない位置になる。
【0025】
別実施例2は、上述のように条止めを行なうと、図9に示すように、本来8条播きの播種機が6条の播種となる。このようにして播種機は、条止め作業を行なうとき、播種した条と播種しない条との区別が、一方は覆土がされた状態になり、他方は播種管2a、2bによる播種溝が圃場表面に残る(播種はされていない)ことによりオペレ−タが視覚によって区別し易くなる特徴がある。

[0003]
[Problems to be solved by the invention]
Conventionally, the cultivation of paddy rice by direct sowing is usually practiced to store water as it is after sowing and to germinate and grow seedlings. It was known that this seedling method can protect young seedlings that are vulnerable to cold from the cold due to the warming effect of the brine, and can grow them as healthy seedlings.
However, in recent years, it has been announced that it is more effective for budding and raising seedlings to drop water after sowing and leave the soil in an oxidized state. According to the test results, it has been announced that it is useful to dry the soil after sowing so hard that it cracks, to prevent lodging after growth and to reduce bird damage.
[0004]
However, conventional sowing machines consider only direct sowing, and it is difficult to quickly drain (fall down) or flood from the field after sowing, and there is a problem that draining and flooding take a long time. It was.
[0005]
[Means for Solving the Problems]
The present invention takes the following technical means in order to solve the above-described problems. That is, a traveling vehicle body (1) provided with steering front wheels (10, 10 ') and propulsion rear wheels (11, 11') is provided, and seeds in the seed tank (5) are fed by the feeding device (6). The seeds are conveyed in the transfer pipe (7) by the compressed air blown out from the air chamber (9) in which the compressed air generated by the wind turbine (8) is stored. In the sowing machine that sows the seeds on the field scene as the traveling vehicle body (1) advances by the sowing pipe (2a, 2b), the sowing pipe (2a, 2b) is configured to reach the sowing pipe (2a, 2b). , 2b) is attached to a float (24) that slides while leveling the topsoil, and a cover plate (25) that can change the angle is provided behind the seeding tubes (2a, 2b), and a groove is formed in the field scene.

[0006]
【The invention's effect】
Since the present invention is configured as described above, in a field with poor drainage, the groover (3) is attached to the rear wheel (11, 11 '), a drainage ditch is created on the trace of passage, so that it can be constructed with a relatively small soil resistance. In the field scene, a ditch (drainage ditch) is placed along the side of the sowing line along with the sowing work. Can be formed. Therefore, drainage and flooding after sowing can be performed very easily, and the effect can be achieved in a short time. Moreover, in a field with good drainage, the rear wheel (as the vehicle moves forward) by removing the grooving device (3) and attaching the rake (35) to the machine frame (28) of the removed portion, 11, 11 '), and the leveling accuracy of the field can be improved.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
First, as shown in FIG. 2 to FIG. 5, the seeder includes seed tank 5, feeding device 6, transfer pipe 7, seeding pipes 2 a and 2 b, and other attached devices such as wind turbine 8 and air chamber 9. It is constructed and mounted on the rear part of the traveling vehicle body 1 as a flooded direct seeder.
[0008]
The traveling vehicle body 1 is provided with front wheels 10 and 10 'for steering and rear wheels 11 and 11' for propulsion, and a control seat 13 is provided on a central engine room 12 to cultivate paddy fields. It is configured to run while rotating on the board. The elevating link 14 is composed of a pair of upper and lower parallel links, the front part is pivotally connected to the rear machine casing 15 of the traveling vehicle body 1, the connecting hitch 16 is attached to the rear part, and the hydraulic cylinder 17 on the vehicle body 1 side is attached. It is configured to move up and down. The hitch 16 is mounted and supported by a seeding machine, which will be described in detail below, and is configured to move up and down freely.
[0009]
Next, the configuration of the seeder will be specifically described based on the drawings.
First, as shown in FIGS. 4 and 5, the feeding device 6 has a feeding roll 19 having a large number of seed grooves 18 formed on the outer periphery facing the lower side of the seed tank 5 so as to be capable of transmission. It is provided with a configuration in which a starting end portion of the transfer pipe 7 that conveys seeds faces the lower end thereof. As shown in FIG. 5, the seed groove 18 has a configuration in which the side storage tool 20 can be slid left and right along the axis by the rotation adjustment operation of the rotation adjustment wheel 21 to adjust the seed storage volume. It is said. Reference numeral 22 denotes an input sprocket.
[0010]
The brush 23 is provided to make the amount of seeds in the seed groove 18 uniform by contacting the surface of the feeding roll 19 and leveling it.
And the seed tank 5 is mounted as one of the structural members of the seeder connected with the rear part of the traveling vehicle body 1, as shown in FIG. 2 and FIG.
Next, as shown in FIG. 4 and FIG. 5, the air chamber 9 is provided in a cylindrical shape and disposed laterally behind the lower side of the feeding device 6, and the wind turbine 8 is connected to one end and the other end It is set as the structure which can store the air ventilated by sealing with a lid | cover. The transfer pipe 7 is opened at its conveyance start end and communicates with the air chamber 9, and is supplied with a predetermined amount of air (air blown) stored in a high pressure state and supplied from above as described above. The seeds are configured to be conveyed by air.
[0011]
In this way, the transfer pipe 7 communicates with the seeding tubes 2a and 2b provided at the sowing position, with the start end communicating with the air chamber 9 and the terminal end extending toward the side close to the farm scene. Configured. The seeding tubes 2a and 2b are provided on the ground surface and attached to a float 24 that slides while leveling the topsoil. The seeding tubes 2a and 2b are configured to be sprayed and seeded in a field scene that has been leveled as it moves forward.
[0012]
As shown in FIG. 1, the earth covering plate 25 is provided so as to be arranged behind the sowing line provided with the above-described seeding tubes 2 a, 2 b, and can cover the earth via the continuous rod 26 and the operation wire 27. It can be changed and adjusted between the angle and the angle that does not cover the soil.
Next, as shown in FIG. 1, the grooving device 3 is provided by being attached to a machine frame 28 that is positioned between the floats 24 and provided horizontally on the front side, and as the traveling vehicle body 1 moves forward. It is configured to form drainage grooves in the farm scene. In the case of the embodiment shown in FIG. 1, the groover 3 is configured at a related position where it proceeds so as to follow the wheel traces through which the rear wheels 11, 11 ′ have passed to form a drainage groove.
[0013]
Then, the groove producing device 3 and the seeding tube 2 may be arranged and arranged at a relative position along the side of the seeding strip so as to form a drainage groove along the side of the seeding strip. The context of can be chosen freely.
In FIG. 3, 29 is a fertilizer tank, 30 is a fertilizer transfer pipe, and 31 is a fertilizer application pipe.
[0014]
The seeder configured in this manner is placed in a field that has been submerged after the leveling work, and the fertilizer tank 29 is filled with fertilizer, and the seed tank 5 is filled with seeds and advanced to start the seeding work. .
Then, as shown in FIG. 4, the seeds in the seed tank 5 reach the feeding roll 19 that rotates downward, and are supplied to the seed grooves 18 on the outer periphery of the feeding roll 19, respectively. Sent to. At that time, the seeds in the seed groove 18 reach the brush 23 on the lower rotation side, the surface is leveled and becomes a fixed amount, and the feeding start end of the lower transfer pipe 7 is accompanied with the rotation of the feeding roll 19. Falls on the part. At that time, in the air chamber 9, the compressed air generated by the wind turbine 8 is stored, and flows into each communicating transfer pipe 7.
[0015]
In this way, the seeds are pneumatically conveyed through the transfer pipe 7 by the compressed air blown from the air chamber 9, reach the seeding pipes 2 a and 2 b on the distal end side, and are cultivated by the float 24. Erupted and seeded. And the soil covering board 25 keeps a predetermined angle with respect to the advancing direction, rakes the top soil, covers the soil on the sowing groove where the seed is sown, and completes the sowing work.
[0016]
In this way, the seeder performs a seeding operation on the field scene that has been flooded as the traveling vehicle body 1 moves forward. At the same time, the grooving device 3 attached to the machine frame 28 is seeded by the seeding tube 2. It is moving forward along the side of the sowing line, forming a drainage groove in a substantially parallel shape. In this case, since the grooving device 3 forms the drainage groove while moving forward on the traces passed through the rear wheels 11, 11 ′, the soil resistance is relatively small, and the grooving device 3 can be grooved with less horsepower consumption. .
[0017]
As described above, the groove that has been grooved simultaneously with the sowing operation by the sowing machine is grooved with water etc. using one end at the water intake in the field and the other end at the drain at the field. It is important to connect so that it can flow easily, and to perform post-treatment so that water can enter and drain easily. In general, paddy fields are required to level the soil surface evenly. However, in large fields, some areas may be low and water may stagnate. There is a risk of failure.
[0018]
In addition, it is known from experience that in the field, the higher the leveling accuracy of the soil surface, the slower the movement of water, and the longer it takes to flood and drain.
Thus, this invention has the peculiar effect which can make a ditch | groove simultaneously with sowing, and can perform drainage | drain and water_inflow rapidly by comprising as demonstrated in the Example.
[0019]
In the first place, the reason for collecting water in the field is to protect the seedlings from the cold by using the heat-retaining effect of the water, but the seeds are resistant to the cold and there is no need to keep the water warm during the period from sowing to germination. Is understood. Rather, it is said that it is better for germination and subsequent growth to dry the field after sowing until the soil is cracked by drainage and leave it in an oxidized state. Then, when the germination is completed and the process proceeds to the stage of raising seedlings, it is necessary to add water to protect the seedlings from the cold, and the water is stored to expect a heat retaining effect.
[0020]
In the process of sowing, germination, and raising seedlings as described above, the present invention is effective when the drainage groove that has been grooved simultaneously with sowing is effective when the drainage and flooding of the field are repeated, and the movement of water is facilitated. Drainage and flooding can be performed.

Next, another embodiment 1 will be described with reference to FIG.
Another embodiment 1 shown in FIG. 6 is configured by attaching a rake 35 freely in place of the groove generator 3. That is, another embodiment 1 is configured such that the soaking operation can be performed while selecting the grooving device 3 and the rake 35 in accordance with the drainage state of the field and replacing the frame with the machine frame 28.
[0022]
As described above, in another embodiment 1, as shown in FIG. 6, in the field with good drainage, the grooving device 3 is removed and the rake 35 is attached to the machine frame 28 at that portion to perform the sowing work. Then, the rake 35 can erase the wheel traces of the rear wheels 11 and 11 ′ while leveling as the vehicle advances, thereby improving the leveling accuracy of the field. Moreover, in a farm field with poor drainage, a drainage groove can be formed by replacing the grooving device 3 (see FIG. 1) and performing sowing work, and water can be moved quickly during drainage and flooding.
[0023]
Example 2
Next, another embodiment 2 will be described with reference to FIGS.
Another embodiment 2 is a configuration related to the streaking of an 8-row seeder used for direct irrigation.
As is widely known from the past, the multi-row sowing machine, like the rice transplanter, stops the line just before the final sowing line in the sowing process, Article 8) It is customary to work so that seeding is possible.
[0024]
First, the clutch lever 40 is connected to a shifter 42 for intermittently operating the clutch device 41 of the seed feeding roll 19 (see FIG. 4) by an operation wire 43 so that the power can be intermittently operated. The clutch lever 40 is configured by connecting the operation wire 44 to the linkage 26 and connecting the angle of the cover plate 25 so that the angle can be changed. Then, when the clutch lever 40 is operated to turn off the clutch device 41 of the feeding roll 19, the cover plate 25 behind the seeding tubes 2a and 2b rotates in conjunction with the angle so that the cover cannot be covered. It is assumed to be configured.
[0025]
In FIG. 7, the clutch lever 40 is located at the solid line in FIG. 7 so that the clutch device 41 is in the transmission state, and the covering plate 25 is at the position shown by the solid line in FIG. Next, when the clutch lever 40 is operated to the position of the imaginary line in FIG. 7, the clutch device 41 becomes the cut position, the feeding roll 19 is stopped, and the covering plate 25 is moved to the phantom line of FIG. The position is adjusted so that the soil cannot be covered.
[0025]
In another example 2, when the streaking is performed as described above, as shown in FIG. Thus, when the seeding machine performs the line-stopping operation, the seeded line and the non-seeded line are distinguished from each other, one is covered with soil, and the other is the seeding groove formed by the seeding tubes 2a and 2b. Therefore, the operator can easily discriminate visually.
