Description

この発明は、施肥装置、播種装置あるいは薬剤散布装置等の粉粒体吐出機を備えた直播機に関する。   The present invention relates to a direct seeder equipped with a powder and particle discharger such as a fertilizer application device, a seeding device, or a drug spraying device.

従来、走行車体の座席より後側に複数の粉粒体繰出部を機体左右方向に並べて設けると共に、粉粒体繰出部の上方に粉粒体を貯留するタンクを設け、粉粒体繰出部から送り出される粉粒体を送風器からの送風により送り出して圃場に連続的に吐出する粉粒体吐出機を備え、圃場面を滑る複数のフロートで前記粉粒体繰出部を支持しながら機体左右方向に配置した直播機が知られている。   Conventionally, a plurality of granular material feeding parts are provided in the left-right direction of the machine body on the rear side of the seat of the traveling vehicle body, and a tank for storing the granular materials is provided above the granular material feeding part, from the granular material feeding part. A left and right direction of the machine body with a powder body discharge machine that sends out the discharged powder body by blowing air from a blower and continuously discharges it to the field while supporting the powder body feeding part with a plurality of floats that slide in the field Direct sowing machines are known.

上記直播機は、トラクタ本体に苗植付部を装着した田植機の苗植付部を取り外して、該苗植付部に粉粒体吐出機を装着して使用するものであり、粉粒体吐出機は田植機におけるトラクタ本体のエンジン動力を変速装置を介して作動される。従って直播機の動力伝達系は苗植付部作動用の田植機の動力伝達系と同一である。
田植機の苗植付部はトラクタ本体のエンジン動力を変速装置から植付クラッチを経由して動力伝達される（特許文献１）。
特開２００７−３２５５２８号公報 The direct seeding machine is used by removing the seedling planting part of the rice transplanter with the seedling planting part attached to the tractor body, and using the seedling planting part with the powder body discharger. The discharger is operated via the transmission with the engine power of the tractor body in the rice transplanter. Therefore, the power transmission system of the direct seeder is the same as the power transmission system of the rice transplanter for operating the seedling planting part.
The seedling planting part of the rice transplanter transmits the engine power of the tractor body from the transmission via the planting clutch (Patent Document 1).
JP 2007-325528 A

上記特許文献１に記載の苗植付部は、トラクタ本体のエンジン動力が植付クラッチを経由して作動するが、該植付クラッチは図示されていないがワンウエイクラッチであり、トラクタ本体の正転と逆転が自在の動力伝達軸から、該動力伝達軸が正転時に苗植付部が作動し、逆転時にはクラッチ爪が外れる一方向クラッチである。   The seedling planting portion described in Patent Document 1 operates with the engine power of the tractor body via a planting clutch, but the planting clutch is a one-way clutch (not shown), and the tractor body is normally rotated. From the power transmission shaft that can freely rotate in the reverse direction, the seedling planting portion operates when the power transmission shaft rotates in the forward direction, and the clutch pawl is released during the reverse rotation.

この苗植付部を構成するワンウエイクラッチが逆転時にクラッチ爪が摩擦で完全に外れないことがある。苗植付部は粉粒体吐出機に比較して作動時の負荷が大きな装置であるので、上記摩擦力に打ち勝つので、動力伝達軸が逆転時に苗植付部を作動させるおそれはないが、粉粒体吐出機はその作動負荷が比較的小さいため作動してしまうことがある。
そこで本発明の課題はトラクタに粉粒体吐出機を連結した場合にトラクタの動力伝達軸が逆転時に粉粒体吐出機を作動させるおそれがない直播機を提供することである。 When the one-way clutch constituting the seedling planting portion is reversely rotated, the clutch pawl may not be completely removed due to friction. Since the seedling planting part is a device that has a large load when operating compared to the powder discharger, it overcomes the frictional force, so there is no risk of operating the seedling planting part when the power transmission shaft reverses, The granular material discharger may operate because its operating load is relatively small.
Accordingly, an object of the present invention is to provide a direct seeding machine in which there is no possibility of operating the granular material discharger when the power transmission shaft of the tractor is reversely rotated when the granular material discharger is connected to the tractor.

本発明の上記課題は、次の解決手段で解決される。
すなわち、エンジン（２０）を搭載した走行車体（２）の後部に複数条分の種子を圃場に播くための直播装置（８２）を走行車体（２）に対して昇降自在に且つ着脱自在に設け、エンジン（２０）からの動力を走行車体（２）側から直播装置（８２）の繰出回転体（８８，８８’）に伝達する動力伝動系を設け、該動力伝動系内において走行車体（２）側と直播装置（８２）側に各々一方向クラッチを設けた直播機である。 The above-mentioned problem of the present invention is solved by the following means.
That is, a direct sowing device (82) for sowing a plurality of seeds on the field is provided at the rear of the traveling vehicle body (2) on which the engine (20) is mounted so as to be movable up and down with respect to the traveling vehicle body (2). A power transmission system is provided for transmitting power from the engine (20) from the traveling vehicle body (2) side to the feeding rotary body (88, 88 ') of the direct seeding device (82), and the traveling vehicle body (2 ) Side and direct seeding device (82) side are direct seeding machines provided with one-way clutches.

本発明によれば、走行車体（２）の後部に連結する直播装置（８２）などの作業装置へエンジン動力を伝動する動力伝動系において、走行車体（２）側に着脱しない一方向クラッチを設けることにより、作業装置の着脱により異なる作業装置を装着しても該作業装置が逆転作動しないようにできる。この走行車体（２）側に設けた一方向クラッチは、例えば苗植付装置（５２）等の駆動抵抗の大きい（例えばトルクで０．１ｋｇ・ｍ程度）各種の作業装置を想定しているから、逆転防止の構造は簡単にでき、コストダウンが図れると共に、装着する作業装置の種類に拘らず兼用できる。   According to the present invention, a one-way clutch that is not attached to and detached from the traveling vehicle body (2) is provided in a power transmission system that transmits engine power to a working device such as a direct seeding device (82) connected to the rear portion of the traveling vehicle body (2). Thus, even if a different work device is mounted by attaching and detaching the work device, the work device can be prevented from rotating in reverse. The one-way clutch provided on the traveling vehicle body (2) side assumes various working devices having a large driving resistance (for example, about 0.1 kg · m in torque) such as a seedling planting device (52). The structure for preventing reverse rotation can be simplified, the cost can be reduced, and the structure can be used regardless of the type of work apparatus to be mounted.

しかしながら、繰出回転体（８８，８８’）を回転させて駆動する直播装置（８２）は、その駆動抵抗が比較的小さいので、前述した走行車体（２）側に設けた一方向クラッチだけで繰出回転体（８８，８８’）の逆転を防ごうとしても、小さな負荷で逆転することがある。   However, the direct seeding device (82) that rotates and drives the feeding rotating body (88, 88 ') has a relatively small driving resistance, so that it is fed only by the one-way clutch provided on the traveling vehicle body (2) side. Even if the rotating body (88, 88 ') is prevented from reversing, it may be reversed with a small load.

しかし本発明のように、直播装置（８２）側に一方向クラッチを設け、逆転時に該直播装置（８２）側の一方向クラッチの面圧で発生する逆回転方向の駆動トルクを直播装置（８２）の駆動抵抗に相当するトルクより小さく（例えばトルクで０．０００１ｋｇ・ｍ以下）すれば、直播装置（８２）が逆転しようとしても確実に逆転しないようにできる。この直播装置（８２）側の一方向クラッチは、高精度で高価となるが、直播装置（８２）側にのみ設けることができるため、直播装置（８２）以外の作業装置を装着する場合は不要となり、コストダウンが図れる。   However, as in the present invention, a one-way clutch is provided on the direct seeding device (82) side, and the reverse sowing direction driving torque generated by the surface pressure of the one-way clutch on the direct seeding device (82) side during the reverse rotation is applied to the direct seeding device (82). ) Less than the torque corresponding to the driving resistance (for example, 0.0001 kg · m or less in torque), it is possible to ensure that the direct seeding device (82) does not reverse even if it tries to reverse. The one-way clutch on the direct seeding device (82) side is highly accurate and expensive, but can be provided only on the direct seeding device (82) side, so it is not necessary when a working device other than the direct seeding device (82) is mounted. Thus, the cost can be reduced.

この発明の実施の一形態を図面に基づき説明する。
本実施例の直播機は乗用４輪駆動走行形態の直播機であり、図１は、施肥装置付きの乗用型の直播機の左側面図を示すものであり、この乗用型の直播機は、走行車体２の後側に昇降リンク装置３を介して直播装置８２が昇降可能に装着され、走行車体２の後部上側に施肥装置５の本体部分が設けられている。図２には直播装置８２に代えて苗植付部４を昇降リンク装置３を介して走行車体２の後部に取り付けた直播機全体の側面図を示し、図３には直播装置８２の機体取付部の拡大側面図を示す。
なお、本明細書では、直播機の前進方向に向って左右方向をそれぞれ左、右とし、前進方向を前、後進方向を後とする。 An embodiment of the present invention will be described with reference to the drawings.
The direct sowing machine of this embodiment is a direct sowing machine in a riding four-wheel drive mode, and FIG. 1 shows a left side view of a riding direct sowing machine with a fertilizer application device. A direct sowing device 82 is mounted on the rear side of the traveling vehicle body 2 via the lifting link device 3 so as to be movable up and down, and a main body portion of the fertilizer application device 5 is provided on the rear upper side of the traveling vehicle body 2. FIG. 2 shows a side view of the entire direct sowing machine in which the seedling planting part 4 is attached to the rear part of the traveling vehicle body 2 via the lifting link device 3 in place of the direct sowing apparatus 82, and FIG. The enlarged side view of a part is shown.
In this specification, the left and right directions are set to the left and right, respectively, in the forward direction of the direct seeding machine, the forward direction is set to the front, and the reverse direction is set to the rear.

走行車体２は、駆動輪である各左右一対の前輪１０，１０及び後輪１１，１１を備えた四輪駆動車両であって、機体の前部にミッションケース１２が配置され、そのミッションケース１２の左右側方に前輪ファイナルケース（図示せず）が設けられ、該前輪ファイナルケースの操向方向を変えることができる前輪支持部から外向きに突出する前輪車軸に前輪１０，１０が取り付けられている。また、ミッションケース１２の背面部にメインフレーム１５の前端部が固着されており、そのメインフレーム１５の後端左右中央部に前後水平に設けた後輪ローリング軸（図示せず）を支点にして後輪ギヤケース１８，１８がローリング自在に支持され、その後輪ギヤケース１８，１８から外向きに突出する後輪車軸に後輪１１，１１が取り付けられている。   The traveling vehicle body 2 is a four-wheel drive vehicle including a pair of left and right front wheels 10 and 10 and rear wheels 11 and 11 as drive wheels, and a transmission case 12 is disposed in the front part of the airframe. A front wheel final case (not shown) is provided on the left and right sides of the front wheel. Yes. Further, the front end portion of the main frame 15 is fixed to the rear portion of the transmission case 12, and a rear wheel rolling shaft (not shown) provided horizontally in the front and rear at the center of the rear end of the main frame 15 is used as a fulcrum. The rear wheel gear cases 18 and 18 are supported in a freely rolling manner, and the rear wheels 11 and 11 are attached to a rear wheel axle that protrudes outward from the rear wheel gear cases 18 and 18.

原動機となるエンジン２０はメインフレーム１５の上に搭載されており、該エンジン２０の回転動力が第一ベルト伝動装置２１などを介して静油圧式変速装置（ＨＳＴ）とミッションケース１２内のミッションに伝達される。ミッションケース１２内のミッションに伝達された回転動力は、変速された後、走行動力と外部取出動力に分離して取り出される。そして、走行動力は、一部が前輪ファイナルケース（図示せず）に伝達されて前輪１０，１０を駆動すると共に、残りが後輪ギヤケース１８，１８に伝達されて後輪１１，１１を駆動する。また、外部取出動力は、カウンタ軸２６を介して走行車体２の後部に設けた植付クラッチケース２５に伝達され、図示しない施肥伝動機構によって施肥装置５へ伝動される。   The engine 20 as a prime mover is mounted on the main frame 15, and the rotational power of the engine 20 is transmitted to the hydrostatic transmission (HST) and the mission in the transmission case 12 via the first belt transmission device 21 and the like. Communicated. The rotational power transmitted to the mission in the mission case 12 is shifted and then separated into traveling power and external power to be extracted. A part of the traveling power is transmitted to the front wheel final case (not shown) to drive the front wheels 10 and 10, and the rest is transmitted to the rear wheel gear cases 18 and 18 to drive the rear wheels 11 and 11. . Further, the external take-out power is transmitted to the planting clutch case 25 provided at the rear portion of the traveling vehicle body 2 via the counter shaft 26 and is transmitted to the fertilizer application device 5 by a fertilizer transmission mechanism (not shown).

また、植付クラッチケース２５内の植付クラッチからドライブシャフト２８を介してエンジン動力が直播装置８２の伝動ケース２９内の直播用クラッチに伝達される。そして、これら苗植付クラッチと直播クラッチは共に一方向クラッチとしている。   Further, engine power is transmitted from the planting clutch in the planting clutch case 25 to the direct seeding clutch in the transmission case 29 of the direct seeding device 82 via the drive shaft 28. These seedling planting clutch and direct sowing clutch are both one-way clutches.

走行車体２の後部に連結する直播装置８２などの作業装置へエンジン動力を伝動する動力伝動系において、着脱しない走行車体２側に一方向クラッチを設けることにより、作業装置の着脱により異なる作業装置を装着しても該作業装置が逆転作動しないようにできる。この走行車体２側に設けた一方向クラッチは、例えば苗植付装置５２等の駆動抵抗の大きい（例えばトルクで０．１ｋｇ・ｍ程度）各種の作業装置を想定しているから、逆転防止の構造は簡単にでき、コストダウンが図れると共に、装着する作業装置の種類に拘らず兼用できる。   In a power transmission system that transmits engine power to a working device such as a direct seeding device 82 that is connected to the rear portion of the traveling vehicle body 2, by providing a one-way clutch on the traveling vehicle body 2 side that is not attached / detached, different working devices can be attached depending on the attachment / detachment of the working device. Even if it is mounted, the working device can be prevented from operating in reverse. The one-way clutch provided on the traveling vehicle body 2 side is assumed to be various working devices having a large driving resistance (for example, about 0.1 kg · m in torque) such as a seedling planting device 52. The structure can be simplified, the cost can be reduced, and it can be used regardless of the type of work device to be mounted.

しかしながら、繰出回転体８８，８８’を回転させて駆動する直播装置８２は、その駆動抵抗が比較的小さいので、前述した走行車体２側に設けた一方向クラッチだけで繰出回転体８８，８８’（図４，図５）の逆転を防ごうとしても、小さな負荷で逆転することがある。しかし本発明のように、直播装置８２側に一方向クラッチを設け、逆転時に該直播装置８２側の一方向クラッチの面圧で発生する逆回転方向の駆動トルクを直播装置８２の駆動抵抗に相当するトルクより小さく（例えばトルクで０．０００１ｋｇ・ｍ以下）すれば、直播装置８２が逆転しようとしても確実に逆転しないようにできる。この直播装置８２側の一方向クラッチは、高精度で高価となるが、直播装置８２側にのみ設けることができるため、直播装置８２以外の作業装置を装着する場合は不要となり、コストダウンが図れる。   However, the direct seeding device 82 that rotates and drives the feeding rotators 88 and 88 ′ has a relatively small driving resistance. Therefore, the feeding rotators 88 and 88 ′ are formed only by the one-way clutch provided on the traveling vehicle body 2 side. Even if it is going to prevent the reverse of (FIG. 4, FIG. 5), it may reverse with a small load. However, as in the present invention, a one-way clutch is provided on the direct seeding device 82 side, and the driving torque in the reverse rotation direction generated by the surface pressure of the one-way clutch on the direct seeding device 82 during reverse rotation corresponds to the drive resistance of the direct seeding device 82. If the torque is smaller than the torque to be applied (for example, 0.0001 kg · m or less in torque), even if the direct seeding device 82 attempts to reverse, the reverse rotation can be reliably prevented. The one-way clutch on the direct seeding device 82 side is highly accurate and expensive, but can be provided only on the direct seeding device 82 side. Therefore, it is not necessary when a working device other than the direct seeding device 82 is mounted, and the cost can be reduced. .

植付クラッチは、駆動側クラッチ体と従動側クラッチ体のクラッチ爪に傾斜面を備え、該傾斜面を滑らせて逆転伝動をさせない形態のクラッチである。直播用クラッチは、外周部に複数の伝動用ローラを備えるローラ型クラッチであり、一般的に市販されているものである。   The planting clutch is a clutch having a configuration in which the clutch claws of the drive side clutch body and the driven side clutch body are provided with inclined surfaces and the inclined surfaces are slid to prevent reverse transmission. The direct seeding clutch is a roller-type clutch having a plurality of transmission rollers on the outer peripheral portion, and is generally commercially available.

エンジン２０の上部はエンジンカバー３０で覆われており、その上に座席３１が設置されている。座席３１の前方には各種操作機構を内蔵するボンネット３２があり、その上方に前輪１０，１０を操向操作するハンドル３４が設けられている。エンジンカバー３０及びボンネット３２の下端左右両側は水平状のフロアステップ３５になっている。   The upper part of the engine 20 is covered with an engine cover 30, and a seat 31 is installed thereon. A bonnet 32 incorporating various operation mechanisms is provided in front of the seat 31, and a handle 34 for steering the front wheels 10, 10 is provided above the bonnet 32. The engine cover 30 and the bonnet 32 have horizontal floor steps 35 on the left and right sides of the lower end.

昇降リンク装置３は平行リンク構成であって、１本の上リンク４０と左右一対の下リンク４１，４１を備えている。これらリンク４０，４１，４１は、その基部側がメインフレーム１５の後端部に立設した背面視門形のリンクベースフレーム４２に回動自在に取り付けられ、その先端側に縦リンク４３が連結されている。そして、メインフレーム１５に固着した支持部材（図示せず）と上リンク４０に一体形成したスイングアーム４５の先端部との間に昇降油圧シリンダ４６が設けられており、該シリンダ４６を油圧で伸縮させることにより、上リンク４０が上下に回動し、直播装置８２がほぼ一定姿勢のまま昇降する。   The elevating link device 3 has a parallel link configuration, and includes one upper link 40 and a pair of left and right lower links 41, 41. These links 40, 41, 41 are pivotally attached to a rear-view portal-shaped link base frame 42 erected on the rear end of the main frame 15, and a vertical link 43 is connected to the tip side thereof. ing. An elevating hydraulic cylinder 46 is provided between a support member (not shown) fixed to the main frame 15 and the tip of a swing arm 45 formed integrally with the upper link 40, and the cylinder 46 is hydraulically expanded and contracted. By doing so, the upper link 40 pivots up and down, and the direct seeding device 82 moves up and down while maintaining a substantially constant posture.

直播装置８２の下部には複数のフロート５５が設けられている。フロート５５を圃場の泥面に接地させた状態で機体を進行させると、フロート５５が泥面を整地しつつ滑走し、その整地跡に直播装置８２，…により種子が播かれる。各フロート５５は圃場表土面の凹凸に応じて前端側が上下動するように回動自在に取り付けられており、直播作業時にはフロート５５の前部の上下動が図示しない上下動検出機構により検出され、その検出結果に応じ前記昇降油圧シリンダ４６を制御する油圧バルブを切り替えて直播装置８２を昇降させることにより、種子の播種深さを常に一定に維持する。   A plurality of floats 55 are provided below the direct seeding device 82. When the aircraft is advanced with the float 55 in contact with the mud surface of the field, the float 55 slides while leveling the mud surface, and seeds are sown by the direct sowing device 82,. Each float 55 is rotatably attached so that the front end side moves up and down according to the unevenness of the field topsoil surface, and the vertical movement of the front part of the float 55 is detected by a vertical movement detection mechanism (not shown) during direct sowing work, By switching the hydraulic valve that controls the lifting hydraulic cylinder 46 according to the detection result, the direct sowing device 82 is raised and lowered, so that the seed sowing depth is always maintained constant.

施肥装置５は、肥料貯留タンク（粉粒体貯留タンク）６０に貯留されている肥料（粉粒体）を走行車体２の左右方向に複数設けられた肥料繰出部（粉粒体繰出部）６１，…によって一定量づつ繰り出し、その肥料を図示しない施肥ホース（粉粒体移送ホース）…でフロート５５の左右両側に取り付けた施肥ガイド（図示せず），…まで導き、施肥ガイド，…の前側に設けた播種用作溝器６４，…によって播種条の側部近傍に形成される施肥溝内に吐出するようになっている。図示していないがモータで駆動されるブロアで発生させた圧力風を左右方向に長いエアチャンバを経由して施肥ホース内に吹き込み、施肥ホース内の肥料を植付部側の肥料吐出口へ強制的に移送するようになっている。   The fertilizer applicator 5 includes a fertilizer feeding part (powder body feeding part) 61 provided with a plurality of fertilizers (powder bodies) stored in a fertilizer storage tank (powder body storage tank) 60 in the left-right direction of the traveling vehicle body 2. The fertilizer is fed by a certain amount, and the fertilizer is guided to a fertilizer guide (not shown) attached to the left and right sides of the float 55 with a fertilizer hose (powder transfer hose) (not shown). Are dispensed into a fertilization groove formed in the vicinity of the side portion of the sowing line.

In addition, muddy water in the field can be blown away with air.

また、直播装置８２から種子を圃場に播く場合、従来は例えばカルパー材をコーティングする等、予め種子のコーティングが行われていたが、このコーティングには時間や手間がかかり、又はせっかくのコーティングが衝撃等により剥がれる事があった。
そこで粘性の高い泡材を用いて、播種の前に種子を泡材でコーティングしておき、これを直播装置８２を用いて圃場に播くことで、圃場に播かれた種子の周りに泡材を介して土がコーティングされた状態となり、予備的なコーティングを行う手間とコストを省いて簡単に種子を圃場に播くことができる。 In addition, when seeds are sown in the field from the direct sowing apparatus 82, conventionally, seed coating has been performed in advance, for example, coating with a calper material. However, this coating takes time and labor, or the precious coating is impacted. It may be peeled off by such as.
Therefore, by using a foam material with high viscosity, seeds are coated with the foam material before sowing, and by seeding the seeds on the field using the direct sowing device 82, the foam material is placed around the seeds sown in the field. Thus, the soil is coated, so that seeds can be easily sown in the field without the labor and cost of preliminary coating.
