Description

本発明は、走行機体に連結される作業機に、植付作業部及び対地作業部を備える乗用田植機などの移植機に関する。   The present invention relates to a transplanter such as a riding rice transplanter provided with a planting work unit and a ground work unit on a work machine connected to a traveling machine body.

走行機体に連結される作業機に、植付作業部及び対地作業部を備える移植機が知られている。例えば、走行機体の後部に連結される植付作業機の前部に、整地ロータを備える乗用田植機が普及している。この種の移植機では、植付けと同時に整地ができるので、植付精度や作業効率の向上を図ることができ、特に、機体旋回によって田面が荒れやすい枕地では、整地ロータによる整地効果が顕著であり、植付精度を大幅に改善することができる。   2. Description of the Related Art A transplanter having a planting work unit and a ground work unit is known as a work machine connected to a traveling machine body. For example, a riding rice transplanter equipped with a leveling rotor at the front part of a planting work machine connected to the rear part of the traveling machine body is widely used. With this type of transplanter, leveling can be done at the same time as planting, so planting accuracy and work efficiency can be improved. Yes, planting accuracy can be greatly improved.

植付作業機に対地作業部を設ける場合、対地作業部の動力を走行機体又は植付作業機から取出す必要がある。植付作業機から外部作業機の動力を取出し可能にしたものとしては、特許文献1に記載される移植機があり、この移植機では、植付作業部を駆動させる植付駆動軸上で外部作業機の動力を分配している。
特開2002−305924号公報
When the ground work unit is provided in the planting work machine, it is necessary to take out the power of the ground work part from the traveling machine body or the planting work machine. As an apparatus that can take out the power of the external working machine from the planting work machine, there is a transplanting machine described in Patent Document 1. In this transplanting machine, there is an external on the planting drive shaft that drives the planting working part. The power of the work equipment is distributed.
JP 2002-305924 A

しかしながら、植付作業部に対する動力伝動系には、過負荷による植付作業部の破損を防止するために、所定のトルクで切り作動するトルクリミッタが設けられているので、特許文献1に記載されるように、植付駆動軸上で外部作業機の動力を分配する場合、トルクリミッタの切りトルクよりも高いトルクを必要とする外部作業機には動力伝動を行うことができず、特に、整地ロータのように対地作業を行う対地作業部に動力伝動を行うことは困難である。尚、対地作業部の必要トルクに合わせて、トルクリミッタの切りトルクを高く設定することも考えられるが、この場合には、過負荷による植付作業部の破損を防止することが困難になる。   However, the power transmission system for the planting work unit is provided with a torque limiter that operates to cut at a predetermined torque in order to prevent damage to the planting work unit due to overload. As described above, when the power of the external work machine is distributed on the planting drive shaft, the power cannot be transmitted to the external work machine that requires a torque higher than the torque limiter cutting torque. It is difficult to perform power transmission to a ground work unit that performs ground work like a rotor. Although it is conceivable to set the torque limiter cutting torque high in accordance with the required torque of the ground working unit, in this case, it becomes difficult to prevent the planting working unit from being damaged due to overload.

本発明は、上記の如き実情に鑑みこれらの課題を解決することを目的として創作されたものであって、走行機体に連結される作業機に、植付作業部と対地作業部とを備えると共に、前記走行機体から前記作業機に伝動される作業機動力を、前記植付作業部と前記対地作業部とに分配する移植機において、前記作業機動力の分配位置から前記植付作業部に至る下流伝動経路に、植付動力用トルクリミッタを設けると共に、前記分配位置の上流伝動経路に、作業機動力用トルクリミッタを設け、該作業機動力用トルクリミッタの切りトルクを、前記植付動力用トルクリミッタの切りトルクよりも高く設定したことを特徴とする。このようにすると、作業機に伝動される作業機動力を、高トルクを必要とする対地作業部にも分配することが可能になる。しかも、植付作業部の上流には、低トルクで切り作動する植付動力用トルクリミッタが設けられるので、過負荷による植付作業部の破損も防止できる。
また、前記作業機動力を、前記作業機の植付動力分配軸上で前記対地作業部と複数の前記植付作業部とに分配すると共に、前記植付動力分配軸から複数の前記植付作業部に至る各下流伝動経路に、それぞれ前記植付動力用トルクリミッタを設けたことを特徴とする。このようにすると、対地作業部の動力を植付動力分配軸から取出すことができるので、伝動構成の簡略化が図れる。
前記作業機動力を、前記作業機の入力ケース内で前記対地作業部と前記植付作業部とに分配すると共に、分配した前記植付作業部の動力を、さらに植付動力分配軸上で複数の前記植付作業部に分配するにあたり、前記入力ケース内の分配位置から前記植付動力分配軸に至る下流伝動経路に前記植付動力用トルクリミッタを設けたことを特徴とする。このようにすると、植付動力用トルクリミッタを植付動力分配軸の下流に設ける場合に比べ、植付動力用トルクリミッタの数を削減することができる。
The present invention was created for the purpose of solving these problems in view of the above circumstances, and includes a planting work unit and a ground work unit in a work machine connected to a traveling machine body. In the transplanter that distributes work machine power transmitted from the traveling machine body to the work machine to the planting work unit and the ground work unit, the work machine power is distributed from the work machine power distribution position to the planting work unit. A torque limiter for planting power is provided in the downstream transmission path, and a torque limiter for work machine power is provided in the upstream transmission path of the distribution position, and the cutting torque of the torque limiter for work machine power is used for the planting power. It is characterized by being set higher than the cutting torque of the torque limiter. If it does in this way, it will become possible to distribute the work machine power transmitted to the work machine also to the ground work part which requires high torque. Moreover, since a planting power torque limiter that operates to cut with low torque is provided upstream of the planting work unit, damage to the planting work unit due to overload can be prevented.
Further, the work machine power is distributed to the ground work unit and the plurality of planting work units on the planting power distribution shaft of the work machine, and a plurality of the planting operations are performed from the planting power distribution shaft. The planting power torque limiter is provided in each downstream transmission path to the section. If it does in this way, since the power of a ground work part can be taken out from a planting power distribution shaft, simplification of a power transmission composition can be attained.
The work machine power is distributed to the ground work unit and the planting work unit in the input case of the work machine, and the distributed power of the planting work unit is further distributed on the planting power distribution shaft. When distributing to the planting working part, the planting power torque limiter is provided in a downstream transmission path from the distribution position in the input case to the planting power distribution shaft. In this way, the number of planting power torque limiters can be reduced as compared with the case where the planting power torque limiter is provided downstream of the planting power distribution shaft.

次に、本発明の実施形態について、図面に基づいて説明する。図1において、1は乗用田植機の走行機体であって、該走行機体1は、機体前部に搭載されるエンジン2、エンジン動力を変速するトランスミッション3、トランスミッション3から出力される走行動力で駆動する前輪4及び後輪5などを備えて構成されると共に、機体後部には、昇降リンク機構6を介して作業機7が昇降自在に連結されている。   Next, embodiments of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a traveling machine body of a riding rice transplanter. The traveling machine body 1 is driven by an engine 2 mounted on the front part of the machine body, a transmission 3 for shifting engine power, and a traveling power output from the transmission 3. A working machine 7 is connected to a rear part of the machine body via an elevating link mechanism 6 so as to be movable up and down.

図2に示すように、トランスミッション3は、主変速機構である静油圧式無段変速装置(HST)8を介してエンジン動力を入力し、これを主クラッチ機構9の下流で走行動力と作業機動力とに分岐させる。分岐した作業機動力は、作業機動力変速機構10、作業機動力用トルクリミッタ11及び作業機クラッチ機構12を経由して作業機PTO軸13から出力され、さらに、伝動軸14を介して作業機7に伝動される。   As shown in FIG. 2, the transmission 3 inputs engine power via a hydrostatic continuously variable transmission (HST) 8 that is a main transmission mechanism, and this is input downstream of the main clutch mechanism 9 to travel power and work mobility. Branch to force. The branched work machine power is output from the work machine PTO shaft 13 via the work machine power transmission mechanism 10, the work machine power torque limiter 11, and the work machine clutch mechanism 12, and is further transmitted via the transmission shaft 14. 7 is transmitted.

図3に示すように、作業機7は、昇降リンク機構6に対してローリング自在に連結される作業機フレーム15、その上方に横送り自在に設けられる苗載台16、作業機フレーム15から後方に延出する複数の植付伝動ケース17、各植付伝動ケース17の後端部に設けられる植付機構(植付作業部)18、植付伝動ケース17の下方に上下揺動自在に設けられるフロート19などを備えて構成されている。   As shown in FIG. 3, the work machine 7 includes a work machine frame 15 that is connected to the elevating link mechanism 6 so as to be able to roll, a seedling stage 16 that is provided so as to be capable of being laterally fed above the work machine frame 15, and a rear side from the work machine frame 15. A plurality of planting transmission cases 17 extending to the plantation, a planting mechanism (planting operation unit) 18 provided at the rear end of each planting transmission case 17, and provided below the planting transmission case 17 so as to be swingable up and down. Provided with a float 19 or the like.

作業機フレーム15の後方には、左右方向に沿う植付動力分配軸20が設けられている。この植付動力分配軸20は、各植付伝動ケース17及び入力ケース21を貫通しており、入力ケース21を介して伝動軸14から植付動力を入力すると共に、これを各植付伝動ケース17に内装される条止めクラッチ機構22及びチェン伝動機構23を介して各植付機構18に伝動する。   A planting power distribution shaft 20 is provided behind the work machine frame 15 along the left-right direction. The planting power distribution shaft 20 penetrates each planting transmission case 17 and the input case 21, and inputs planting power from the transmission shaft 14 via the input case 21, and supplies this to each planting transmission case. 17 is transmitted to each planting mechanism 18 through a strut clutch mechanism 22 and a chain transmission mechanism 23 housed in 17.

また、植付動力分配軸20の並列位置には、苗載台16の横送り作動を行う横送り軸24が設けられている。横送り軸24は、外周にラセン溝24aを有するスクリュ軸であり、その外周には、ラセン溝24aに噛み合い、かつ、苗載台16の背面に連結されるスライドブロック(図示せず)が嵌合されている。これにより、横送り軸24の回転に応じてスライドブロック(図示せず)が左右方向に往復移動し、苗載台16の横送りが行われる。   Further, at the parallel position of the planting power distribution shaft 20, a lateral feed shaft 24 that performs the lateral feed operation of the seedling mounting table 16 is provided. The lateral feed shaft 24 is a screw shaft having a spiral groove 24a on the outer periphery, and a slide block (not shown) that engages with the spiral groove 24a and is connected to the back surface of the seedling table 16 is fitted on the outer periphery. Are combined. As a result, a slide block (not shown) reciprocates in the left-right direction according to the rotation of the lateral feed shaft 24, and the seedling stage 16 is laterally fed.

横送り軸24は、植付動力分配軸20よりも軸長が短く、かつ、植付動力分配軸20の右端側に偏倚して配置されると共に、横送りケース26を介して植付動力分配軸20の右端部から取り出した動力で回転駆動される。本実施形態の横送りケース26は、横送り変速機構27を内装しており、該横送り変速機構27の変速操作に応じて、苗載台16の横送り速度が変更される。   The lateral feed shaft 24 has a shorter shaft length than the planting power distribution shaft 20, is biased to the right end side of the planting power distribution shaft 20, and is planted power distribution via the lateral feed case 26. The shaft 20 is rotationally driven by the power extracted from the right end portion of the shaft 20. The lateral feed case 26 of this embodiment includes a lateral feed transmission mechanism 27, and the lateral feed speed of the seedling table 16 is changed according to the speed change operation of the lateral feed transmission mechanism 27.

上記のように構成される作業機7によれば、伝動軸14を介してトランスミッション3から作業機動力を入力し、この動力によって、苗載台16を横送りしつつ、植付機構18による植付作業が可能になる。植付作業を行う圃場は、予め代掻き作業によって平坦化されており、ここをフロート19が滑走しつつ、植付機構18による苗の植付けが行われることになるが、作業機7は、走行機体1の後方で植付作業を行う関係上、車輪跡などによる田面の荒れによって植付精度が低下する可能性がある。特に、機体旋回が行われる枕地は、車輪跡による田面の荒れが顕著であり、植付精度が低下しやすい箇所である。   According to the work machine 7 configured as described above, work machine power is input from the transmission 3 via the transmission shaft 14, and the seedling mounting table 16 is laterally fed by this power while the planting mechanism 18 performs the planting. Attached work becomes possible. The field where the planting operation is carried out is flattened by a scraping operation in advance, and the planting seedling is planted by the planting mechanism 18 while the float 19 slides there. The planting accuracy may be reduced due to rough rice fields due to wheel marks, etc., because the planting operation is performed behind 1. In particular, the headland where the airframe is turned is a place where the roughness of the surface due to the wheel marks is remarkable, and the planting accuracy tends to decrease.

上記のような問題に対処するために、作業機7の前側には、整地ロータ(対地作業部)28が設けられている。この整地ロータ28は、側面視で後輪5とフロート19との間に配置され、フロート19の前側で整地作業を行う。これにより、車輪跡による田面の荒れなどを改善し、植付精度を高めることができ、特に、枕地において改善効果が顕著である。   In order to deal with the above problems, a leveling rotor (ground work unit) 28 is provided on the front side of the work machine 7. The leveling rotor 28 is disposed between the rear wheel 5 and the float 19 in a side view, and performs leveling work on the front side of the float 19. Thereby, the roughening of the surface by a wheel trace, etc. can be improved, and a planting precision can be raised, and especially the improvement effect is remarkable in a headland.

図1〜図3に示すように、整地ロータ28は、作業機7の左右幅に亘って一連状に形成されるロータ軸29と、該ロータ軸29に一体的に設けられる複数の整地板30とを備えて構成されると共に、整地ロータ用動力取出し部31を介して植付動力分配軸20から取り出し、該動力で整地板30を所定方向に回転させることにより、作業機7の前方で整地作業を行う。   As shown in FIGS. 1 to 3, the leveling rotor 28 includes a rotor shaft 29 formed in a series over the left and right widths of the work machine 7, and a plurality of leveling plates 30 provided integrally with the rotor shaft 29. The ground leveling rotor 30 is taken out from the planting power distribution shaft 20 via the leveling rotor power take-out unit 31, and the leveling plate 30 is rotated in a predetermined direction by the power, thereby leveling the ground in front of the work machine 7. Do work.

整地ロータ用動力取出し部31は、整地ロータ用クラッチ機構32を内装するクラッチケース33と、チェン伝動機構34を内装するチェンケース35とを備えて構成され、植付動力分配軸20の左端部から整地ロータ28の動力を取出す。つまり、横送り軸24を植付動力分配軸20の一端側に偏倚して設ける一方、整地ロータ用動力取出し部31を植付動力分配軸20の他端側に設け、該植付動力分配軸20から整地ロータ用クラッチ機構32を介して整地ロータ28の動力を取出すので、作業機7における左右の重量バランスを崩すことなく、植付動力分配軸20の端部から整地ロータ28の動力を取出すことが可能になる。しかも、植付動力分配軸20から整地ロータ用クラッチ機構32を介して整地ロータ28の動力を取出すので、整地が不要な場合、整地ロータ28を作動させずに植付作業を行うことができる。   The leveling rotor power take-out unit 31 includes a clutch case 33 in which the leveling rotor clutch mechanism 32 is housed, and a chain case 35 in which a chain transmission mechanism 34 is housed, and from the left end of the planting power distribution shaft 20. The power of the leveling rotor 28 is taken out. That is, the lateral feed shaft 24 is provided to be biased to one end side of the planting power distribution shaft 20, while the leveling rotor power take-out portion 31 is provided to the other end side of the planting power distribution shaft 20, and the planting power distribution shaft is provided. 20, the power of the leveling rotor 28 is taken out via the leveling rotor clutch mechanism 32, so that the power of the leveling rotor 28 is taken out from the end of the planting power distribution shaft 20 without breaking the left and right weight balance in the work machine 7. It becomes possible. Moreover, since the power of the leveling rotor 28 is taken out from the planting power distribution shaft 20 via the leveling rotor clutch mechanism 32, when leveling is unnecessary, the planting operation can be performed without operating the leveling rotor 28.

また、走行機体1から作業機7に伝動される作業機動力を、植付機構18と整地ロータ28とに分配するにあたり、作業機動力の分配位置(本実施形態では、植付動力分配軸20)から植付機構18に至る下流伝動経路に、植付動力用トルクリミッタ36を設けると共に、分配位置の上流伝動経路に、前述の作業機動力用トルクリミッタ11を設け、該作業機動力用トルクリミッタ11の切りトルクを、植付動力用トルクリミッタ36の切りトルクよりも高く設定している。このようにすると、作業機7に伝動される作業機動力を、高トルクを必要とする整地ロータ28にも分配することが可能になるだけでなく、植付機構18の上流に、低トルクで切り作動する植付動力用トルクリミッタ36を配し、過負荷による植付機構18の破損も防止できる。   Further, when distributing the work machine power transmitted from the traveling machine body 1 to the work machine 7 to the planting mechanism 18 and the leveling rotor 28, the work machine power distribution position (in this embodiment, the planting power distribution shaft 20). ) To the planting mechanism 18 is provided with a planting power torque limiter 36, and the work machine power torque limiter 11 is provided on the upstream transmission path of the distribution position. The cutting torque of the limiter 11 is set higher than the cutting torque of the planting power torque limiter 36. In this way, the work machine power transmitted to the work machine 7 can be distributed not only to the leveling rotor 28 that requires high torque, but also at a low torque upstream of the planting mechanism 18. The planting power torque limiter 36 that performs the cutting operation can be provided to prevent the planting mechanism 18 from being damaged due to overload.

また、本実施形態では、作業機動力を、作業機7の植付動力分配軸20上で整地ロータ28と複数の植付機構18とに分配すると共に、植付動力分配軸20から複数の植付機構18に至る各下流伝動経路に、それぞれ植付動力用トルクリミッタ36を設けている。具体的には、植付機構18の駆動軸18aとチェン伝動機構23との間に植付動力用トルクリミッタ36を介設している。このようにすると、整地ロータ28の動力を植付動力分配軸20から取出すことができるので、伝動構成の簡略化が図れる。   Further, in the present embodiment, work machine power is distributed to the leveling rotor 28 and the plurality of planting mechanisms 18 on the planting power distribution shaft 20 of the work machine 7, and a plurality of planting powers are planted from the planting power distribution shaft 20. A planting power torque limiter 36 is provided in each downstream transmission path to the attaching mechanism 18. Specifically, a planting power torque limiter 36 is interposed between the drive shaft 18 a of the planting mechanism 18 and the chain transmission mechanism 23. In this way, the power of the leveling rotor 28 can be taken out from the planting power distribution shaft 20, so that the transmission configuration can be simplified.

叙述の如く構成された本実施形態によれば、走行機体1に連結される作業機7に、植付作業部である植付機構18と、対地作業部である整地ロータ28とを備えると共に、走行機体1から作業機7に伝動される作業機動力を、植付機構18と整地ロータ28とに分配する乗用田植機において、作業機動力の分配位置から植付機構18に至る下流伝動経路に、植付動力用トルクリミッタ36を設けると共に、分配位置の上流伝動経路に、作業機動力用トルクリミッタ11を設け、該作業機動力用トルクリミッタ11の切りトルクを、植付動力用トルクリミッタ36の切りトルクよりも高く設定したので、作業機7に伝動される作業機動力を、高トルクを必要とする整地ロータ28にも分配することが可能になる。しかも、植付機構18の上流には、低トルクで切り作動する植付動力用トルクリミッタ36が設けられるので、過負荷による植付機構18の破損も防止できる。   According to the present embodiment configured as described, the working machine 7 connected to the traveling machine body 1 includes the planting mechanism 18 that is a planting work unit and the leveling rotor 28 that is a ground work unit, In a riding rice transplanter that distributes the work machine power transmitted from the traveling machine body 1 to the work machine 7 to the planting mechanism 18 and the leveling rotor 28, the downstream power transmission path from the work machine power distribution position to the planting mechanism 18 In addition to providing the planting power torque limiter 36, the work machine power torque limiter 11 is provided in the upstream transmission path of the distribution position, and the cutting torque of the work machine power torque limiter 11 is changed to the planting power torque limiter 36. Therefore, the work machine power transmitted to the work machine 7 can be distributed to the leveling rotor 28 that requires high torque. In addition, since the planting power torque limiter 36 that operates to cut at low torque is provided upstream of the planting mechanism 18, damage to the planting mechanism 18 due to overload can be prevented.

また、本実施形態では、作業機動力を、作業機7の植付動力分配軸20上で整地ロータ28と複数の植付機構18とに分配すると共に、植付動力分配軸20から複数の植付機構に至る各下流伝動経路に、それぞれ植付動力用トルクリミッタ36を設けているので、整地ロータ28の動力を植付動力分配軸20から取出し、伝動構成の簡略化が図れる。   Further, in the present embodiment, work machine power is distributed to the leveling rotor 28 and the plurality of planting mechanisms 18 on the planting power distribution shaft 20 of the work machine 7, and a plurality of planting powers are planted from the planting power distribution shaft 20. Since the planting power torque limiter 36 is provided in each downstream transmission path to the attachment mechanism, the power of the leveling rotor 28 can be taken out from the planting power distribution shaft 20 to simplify the transmission configuration.

尚、本発明は、前記実施形態に限定されないことは勿論であって、例えば、図4に示す第二実施形態のように構成してもよい。すなわち、第二実施形態においては、作業機動力を、作業機7の入力ケース37内に設けた作業機動力分配軸38上で整地ロータ28と植付機構18とに分配すると共に、分配した植付機構18の動力を、さらに植付動力分配軸20上で複数の植付機構18に分配するにあたり、入力ケース37内の作業機動力分配軸38から植付動力分配軸20に至る下流伝動経路に植付動力用トルクリミッタ39を設けている。このようにすると、第一実施形態のように植付動力分配軸20の下流経路にそれぞれ植付動力用トルクリミッタ36を設ける場合に比べ、植付動力用トルクリミッタ39の数を削減することができる。   Of course, the present invention is not limited to the above-described embodiment, and may be configured, for example, as in the second embodiment shown in FIG. That is, in the second embodiment, the work machine power is distributed to the leveling rotor 28 and the planting mechanism 18 on the work machine power distribution shaft 38 provided in the input case 37 of the work machine 7, and the distributed planting is performed. When the power of the attaching mechanism 18 is further distributed to the plurality of planting mechanisms 18 on the planting power distribution shaft 20, the downstream transmission path from the work machine power distribution shaft 38 in the input case 37 to the planting power distribution shaft 20. Is provided with a torque limiter 39 for planting power. In this case, the number of planting power torque limiters 39 can be reduced as compared with the case where the planting power torque limiter 36 is provided in the downstream path of the planting power distribution shaft 20 as in the first embodiment. it can.
