Description

サトウキビ収穫機Sugarcane harvester
　本発明は、圃場に植立している作物（サトウキビ）を収穫するサトウキビ収穫機に関する。 The present invention relates to a sugarcane harvester that harvests crops (sugarcane) planted in a field.
　サトウキビ収穫機は、機体前下部に位置する収穫部により、植立している作物を収穫し、収穫した作物を搬送装置により機体後上方に向けて搬送して回収するように構成されている。そして、機体各部に備えられた複数の作動機構の全てのものが、例えば、油圧モータや油圧シリンダ等の油圧アクチュエータにて構成されていた。これらの複数の油圧アクチュエータは、エンジンにて駆動される油圧ポンプから供給される作動油によって作動する（例えば、特許文献１参照）。 The sugarcane harvesting machine is configured to harvest planted crops by a harvesting unit located in the lower front part of the machine, and to convey the harvested crops to the upper rear of the machine and collect them. All of the plurality of operating mechanisms provided in each part of the machine body are configured by hydraulic actuators such as a hydraulic motor and a hydraulic cylinder, for example. The plurality of hydraulic actuators are operated by hydraulic oil supplied from a hydraulic pump driven by the engine (see, for example, Patent Document 1).
日本国特開２０１５－２０２０８６号公報Japanese Unexamined Patent Publication No. 2015-202086
　上記したような油圧アクチュエータは、動力を機械的に伝達する動力伝達機構に比べて動力伝達効率が低い。動力伝達効率は、エンジンの動力が伝達された駆動入力に対する作動機構を作動するときの駆動出力の比率である。しかも、サトウキビ収穫機においては、作動機構の個数が多いので、上記従来構成では、複数の作動機構の全てにおいて必要とされる操作用動力を得るために大出力のエンジンを搭載しなければならず、エンジンが大型化して、機体全体の大型化やコスト高を招く等の不利な面があった。 The hydraulic actuator as described above has lower power transmission efficiency than a power transmission mechanism that mechanically transmits power. The power transmission efficiency is a ratio of the drive output when the operation mechanism is operated with respect to the drive input to which the engine power is transmitted. In addition, since the number of operating mechanisms is large in a sugarcane harvesting machine, in the above-described conventional configuration, a high-power engine must be mounted in order to obtain operating power required for all of the plurality of operating mechanisms. However, there are disadvantages such as an increase in the size of the engine, which leads to an increase in the size of the entire aircraft and high costs.
　そこで、機体全体のコンパクト化やコスト低減を図ることが可能なサトウキビ収穫機が要望されていた。 Therefore, there has been a demand for a sugarcane harvester that can reduce the overall size and reduce the cost.
　本発明に係るサトウキビ収穫機の特徴構成は、
　エンジンと、
　前記エンジンの動力によって駆動される油圧ポンプと、
　前記油圧ポンプからの油圧で作動する油圧アクチュエータと、
　前記エンジンからの動力を機械的に伝達する動力伝達機構と、
　前記油圧アクチュエータにて作動される油圧操作式の作動機構と、
　前記動力伝達機構からの動力にて作動される機械式の作動機構とが備えられている点にある。 The characteristic configuration of the sugarcane harvester according to the present invention is as follows:
Engine,
A hydraulic pump driven by the power of the engine;
A hydraulic actuator that operates with hydraulic pressure from the hydraulic pump;
A power transmission mechanism for mechanically transmitting power from the engine;
A hydraulically operated actuation mechanism actuated by the hydraulic actuator;
And a mechanical operation mechanism that is operated by power from the power transmission mechanism.
　本発明によれば、エンジンの動力によって油圧ポンプが駆動され、油圧ポンプからの油圧で油圧アクチュエータが作動する。油圧アクチュエータは油圧操作式の作動機構を作動させる。これに対して、機械式の作動機構に対しては、エンジンの動力が動力伝達機構を介して機械的に伝達され、その動力によって作動される。 According to the present invention, the hydraulic pump is driven by the engine power, and the hydraulic actuator is operated by the hydraulic pressure from the hydraulic pump. The hydraulic actuator operates a hydraulically operated operating mechanism. On the other hand, the engine power is mechanically transmitted to the mechanical operation mechanism via the power transmission mechanism, and is operated by the power.
　油圧アクチュエータは動力伝達効率が低いが、機械的に動力伝達が行われる動力伝達機構は動力伝達効率が高い。その結果、全ての作動機構を油圧アクチュエータで作動させる構成に比べて、収穫機全体としての動力伝達効率が高くなるので、エンジンを低出力化させることが可能である。 The hydraulic actuator has low power transmission efficiency, but the power transmission mechanism that mechanically transmits power has high power transmission efficiency. As a result, the power transmission efficiency of the harvesting machine as a whole is higher than that of a configuration in which all the operation mechanisms are operated by hydraulic actuators, so that the output of the engine can be reduced.
　従って、エンジンを小型化させることにより、機体全体のコンパクト化やコスト低減を図ることが可能となった。 Therefore, it has become possible to reduce the overall size of the aircraft and reduce costs by reducing the size of the engine.
　本発明においては、前記エンジンの出力軸から前記動力伝達機構に動力が伝達され、
　前記エンジンの出力軸から前記油圧ポンプの入力軸に動力を伝達するポンプ用伝動機構と、前記油圧ポンプの入力軸から走行用駆動装置に動力を伝達する走行用伝動機構とが備えられていると好適である。 In the present invention, power is transmitted from the output shaft of the engine to the power transmission mechanism,
A pump transmission mechanism for transmitting power from the output shaft of the engine to the input shaft of the hydraulic pump; and a traveling transmission mechanism for transmitting power from the input shaft of the hydraulic pump to the traveling drive device. Is preferred.
　例えば、エンジンの出力軸から、動力伝達機構及び油圧ポンプに加えて、走行用駆動装置に対しても動力伝達される構成にすると、エンジンの出力軸に動力取り出し用の回転体を多く装着しなければならず、出力軸が長くなってエンジンの設置スペースが大きくなるとともに、出力軸に対する駆動負荷が大きくなるので、出力軸の強度を大きくしなければならない。 For example, if the power is transmitted from the engine output shaft to the driving device in addition to the power transmission mechanism and the hydraulic pump, a large number of rotating bodies for power extraction must be mounted on the engine output shaft. As a result, the output shaft becomes longer and the installation space of the engine becomes larger, and the driving load on the output shaft becomes larger. Therefore, the strength of the output shaft must be increased.
　これに対して、本構成では、油圧ポンプの入力軸を走行用駆動装置に動力伝達するための中継用伝動軸として兼用することで、エンジンの出力軸には、走行用駆動装置に対する動力取り出し用の回転体を装着する必要がなく、出力軸を短くすることができ、エンジンの設置スペースをコンパクトにできるとともに、出力軸に対する駆動負荷を軽減することができる。 On the other hand, in this configuration, the input shaft of the hydraulic pump is also used as a relay transmission shaft for transmitting power to the travel drive device, so that the output shaft of the engine can be used to extract power from the drive device for travel. It is not necessary to mount the rotating body, the output shaft can be shortened, the installation space of the engine can be made compact, and the driving load on the output shaft can be reduced.
　本発明においては、前記エンジンを支持する機体フレームが備えられ、
　前記エンジンは、前記エンジンの出力軸が前記機体フレームよりも上側に位置する状態で備えられ、
　前記油圧ポンプは、前記油圧ポンプの入力軸が前記機体フレームよりも下側に位置する状態で備えられ、
　前記走行用伝動機構は、前記走行用伝動機構の入力軸が前記機体フレームよりも上側に位置する状態で備えられていると好適である。 In the present invention, a body frame for supporting the engine is provided,
The engine is provided in a state where the output shaft of the engine is positioned above the fuselage frame,
The hydraulic pump is provided in a state where an input shaft of the hydraulic pump is positioned below the body frame,
It is preferable that the travel transmission mechanism is provided in a state where an input shaft of the travel transmission mechanism is positioned above the body frame.
　エンジンと、油圧ポンプと、走行用伝動機構とを備える場合、それらの各装置を全て機体フレームよりも上側に位置させて水平方向に並ぶ状態で備える構成が考えられる。しかし、このような構成では、水平方向、例えば、機体横幅方向あるいは機体前後方向に沿って設置スペースが大型化してしまう不利がある。 When an engine, a hydraulic pump, and a traveling transmission mechanism are provided, it is conceivable that all of these devices are positioned above the fuselage frame and arranged in a horizontal direction. However, in such a configuration, there is a disadvantage that the installation space is increased in the horizontal direction, for example, in the horizontal direction of the aircraft or in the longitudinal direction of the aircraft.
　しかし、本構成では、動力中継用の油圧ポンプの入力軸が機体フレームよりも下側に位置するように油圧ポンプを設けることにより、機体フレームの上側における設置スペースのコンパクト化を図ることができる。しかも、油圧ポンプを低い位置に設置することで、機体全体の重心位置を下げるという利点もある。 However, in this configuration, the installation space above the fuselage frame can be made compact by providing the hydraulic pump so that the input shaft of the hydraulic pump for power relay is located below the fuselage frame. Moreover, there is an advantage that the center of gravity of the entire machine body is lowered by installing the hydraulic pump at a low position.

It is possible to reliably avoid the damage caused by adding to the cutting device.

　切断装置、掻き込み装置、及び、搬送装置は、植立している作物を収穫するために一連に連なる状態で設けられ、収穫物に作用するものである。その結果、収穫物の搬送詰まりや巻付き等によって作動が阻害されて大きな駆動力が必要になることがある。 The cutting device, the raking device, and the conveying device are provided in a series of states for harvesting the planted crop, and act on the crop. As a result, the operation may be hindered due to clogging or winding of the harvested product, and a large driving force may be required.

As compared with the above, the required power of the engine can be reduced, and as a result, the engine can be downsized.
　本発明においては、前記動力伝達機構は、前記エンジンからの動力を、前記搬送装置に伝達し、且つ、前記搬送装置に伝達された動力を前記切断装置及び前記掻き込み装置に伝達するように構成され、

　収穫作業中は、逆転機構を正転状態に切り換えておくことで、搬送装置、切断装置及び掻き込み装置の夫々が正転状態で駆動されるので適正な収穫作業を行える。作業途中において、搬送詰まりや巻付き等が発生した場合には、逆転機構を逆転状態に切り換える。そうすると、搬送装置、切断装置及び掻き込み装置の夫々が収穫作業用の正転状態と逆方向に駆動される。つまり、収穫物の詰まり状態や巻付き状態を緩める方向に各装置を回動させて、詰まりや巻付きを解除することができる。その結果、詰まっている作物や巻付いている作物を取り除くことが可能となる。 During the harvesting operation, by switching the reverse rotation mechanism to the normal rotation state, each of the transport device, the cutting device and the scraping device is driven in the normal rotation state, so that an appropriate harvesting operation can be performed. In the middle of the work, when a conveyance jam or winding occurs, the reverse rotation mechanism is switched to the reverse rotation state. Then, each of the conveying device, the cutting device, and the scraping device is driven in the direction opposite to the normal rotation state for the harvesting operation. That is, it is possible to release the clogging and winding by rotating each device in a direction to loosen the clogged state and the winding state of the harvest. As a result, it is possible to remove clogged and wound crops.

　本構成によれば、機体前部に設けられる分草装置は縦回転式すなわち、上下方向の軸芯周りで回転される。これに対してエンジンの出力軸は横向き姿勢である場合が多く、エンジンからの動力を機械的に伝達する構成では、伝動構造が複雑になるおそれがある。そこで、分草装置を油圧アクチュエータにて作動させる構成とすることで、駆動構造を簡素にできるとともに、メンテナンスも容易となる。 According to this configuration, the weeding device provided in the front part of the machine body is vertically rotated, that is, rotated about the vertical axis. On the other hand, the output shaft of the engine is often in a sideways posture, and in a configuration that mechanically transmits power from the engine, the transmission structure may be complicated. Therefore, by adopting a configuration in which the weeding device is operated by a hydraulic actuator, the drive structure can be simplified and maintenance can be facilitated.

When the separation device is switched to the retracted position, it retracts to the lower side than the working position, so it can be stored in a compact shape by lowering the vertical height and loaded on the truck bed when transporting the sugarcane harvester etc. When you do this, you can keep the ground clearance low.
　姿勢切換機構は、分離装置を作用姿勢と格納姿勢との２位置に切り換えるものであり、例えば、油圧シリンダ等の一般的な油圧アクチュエータを用いることができ、配置構成に制約を受けることがなく、伝動構造を簡素にできるとともに、メンテナンスも容易となる。 The posture switching mechanism switches the separation device between two positions, that is, an action posture and a retracted posture. For example, a general hydraulic actuator such as a hydraulic cylinder can be used, and the arrangement configuration is not restricted. The transmission structure can be simplified and maintenance can be facilitated.

A discharge case 55 in which a discharge port 54 is formed, a fan 50 that is positioned inside the main body case 53 and rotates around the vertical axis, and the left and right side wall portions 33 of the transfer device 6. And a support frame 56 that supports the entire separation device 7.
　支持フレーム５６は、本体ケース５３の周方向に異なる箇所から排出用ケース５５の外周部を迂回するように上方に向けて円弧状に延設され、且つ、上端部が互いに連結された４本の支持アーム５７と、４本の支持アーム５７の上部の連結箇所に設けられた回動ボス部５８とを備えている。４本の支持アーム５７の下端部は、本体ケース５３の上部において周方向に異なる箇所に設けられた連結部５９に夫々連結されている。 The support frame 56 extends upward in an arc shape so as to bypass the outer periphery of the discharge case 55 from different locations in the circumferential direction of the main body case 53, and has four upper ends connected to each other. A support arm 57 and a rotating boss portion 58 provided at a connection portion at the top of the four support arms 57 are provided. The lower ends of the four support arms 57 are respectively connected to connecting portions 59 provided at different locations in the circumferential direction on the upper portion of the main body case 53.
　回動ボス部５８には、排出用ケース５５及び本体ケース５３の内部を通して下方に延びる筒状ケース６０が支持されている。筒状ケース６０内にファン駆動軸（図示せず）が回転可能に支持され、筒状ケース６０の上端部には油圧モータ６１（以下、ファンモータと略称する）が備えられ、ファン駆動軸の下端部にはファン５０が備えられている。 A cylindrical case 60 extending downward through the inside of the discharge case 55 and the main body case 53 is supported by the rotating boss portion 58. A fan drive shaft (not shown) is rotatably supported in the cylindrical case 60, and a hydraulic motor 61 (hereinafter abbreviated as a fan motor) is provided at the upper end of the cylindrical case 60. A fan 50 is provided at the lower end.
　図１０に示すように、本体ケース５３の下部側の開口（図示せず）が、搬送装置６の後端部の上方に臨む状態で備えられている。ファン５０が、ファン５０の下方側の空間からファン５０の上方側の空間に向けて空気を流動させるように通風する。このようにファン５０が通風作用することにより、本体ケース５３の下部側の開口を通して、搬送装置６の後端部から排出される収穫物に含まれる細かな茎稈屑や葉切れ等の比較的軽い夾雑物を、ファン５０の風力により吸引して排出用ケース５５を介して排出口５４から外方に排出する。従って、油圧式のファンモータ６１を備えて、収穫物と夾雑物とを分離するファン駆動式の分離装置７が、油圧操作式の作動機構ＹＳを構成する。 As shown in FIG. 10, an opening (not shown) on the lower side of the main body case 53 is provided so as to face above the rear end of the transfer device 6. The fan 50 is ventilated so that air flows from the space below the fan 50 toward the space above the fan 50. As the fan 50 is ventilated in this way, through the opening on the lower side of the main body case 53, relatively small stalks and leaf breaks included in the harvested product discharged from the rear end of the transport device 6. Light impurities are sucked by the wind force of the fan 50 and discharged outward from the discharge port 54 via the discharge case 55.

A lowering guide plate 63 is provided below the conveying terminal end of the conveying conveyor 123 to guide the harvested items downward and downward.
　搬送装置６の後端部から排出される収穫物は、排出される途中でファン５０による吸引作用を受けて、細かな茎稈屑や葉切れ等の比較的軽い夾雑物は吸引される。ファン５０により吸引されなかった収穫物は、搬送コンベア１２３に落下して後方に搬送されるが、この搬送途中においても、軽い夾雑物はファン５０による吸引作用を受けて吸引されることになる。つまり、搬送コンベア１２３を備えることで、ファン５０による選別作用を受ける経路を長くすることで分離用の選別効率を向上させることができる。 The harvested product discharged from the rear end of the conveying device 6 is sucked by the fan 50 in the middle of discharging, and relatively light impurities such as fine stalks and leaves are sucked. The harvest that has not been sucked by the fan 50 falls onto the transport conveyor 123 and is transported rearward. Even during the transport, the light impurities are sucked by the suction action of the fan 50. That is, by providing the conveyor 123, it is possible to improve the separation efficiency for separation by lengthening the path that receives the sorting action by the fan 50.
　図１１に示すように、搬送コンベア１２３は、搬送始端側に設けられた横向きの支持軸１２４の軸芯周りで上下揺動自在に側壁部３３に支持されている。そして、搬送コンベア１２３の前後途中部に設けられた支持ピン１２５が側壁部３３に取付けられた支持部材１２６の先端部にて支持されている。支持部材１２６は、支持ピン１２５を支持するための挿通孔１２７が３個形成されている。支持ピン１２５を異なる挿通孔１２７に支持することで、搬送コンベア１２３の搬送終端側箇所の上下位置を変更することができる。例えば、収穫物の茎の大きさの違いや夾雑物の含有量の違い等に応じて、上下位置を変更することで、選別精度を向上させることができる。 As shown in FIG. 11, the transport conveyor 123 is supported by the side wall 33 so as to be swingable up and down around the axis of a lateral support shaft 124 provided on the transport start end side. And the support pin 125 provided in the front-rear middle part of the conveyance conveyor 123 is supported by the front-end | tip part of the support member 126 attached to the side wall part 33. As shown in FIG. The support member 126 has three insertion holes 127 for supporting the support pins 125. By supporting the support pins 125 in different insertion holes 127, the vertical position of the conveyance terminal side portion of the conveyance conveyor 123 can be changed. For example, the selection accuracy can be improved by changing the vertical position according to the difference in the size of the stalks of the harvest, the difference in the content of impurities, and the like.
　搬送コンベアから排出される収穫物は流下案内板６３によって、後方下方側の排出コンベア８の搬送始端部に案内される。図１，２に示すように、排出コンベア８の搬送始端部の外周部には、落下排出される収穫物を広い面積で受止めて、排出コンベア８の搬送始端部に案内する受止め案内部６４（一時貯留部の一例）が設けられている。 The harvested product discharged from the transport conveyor is guided by the flow guide plate 63 to the transport start end of the discharge conveyor 8 on the lower rear side. As shown in FIGS. 1 and 2, on the outer peripheral portion of the conveyance start end portion of the discharge conveyor 8, a receiving guide portion that receives the fallen and discharged crop in a wide area and guides it to the conveyance start end portion of the discharge conveyor 8. 64 (an example of a temporary storage unit) is provided.
　排出用ケース５５は本体ケース５３に対して上下軸芯Ｙ１周りで相対回動可能且つ上下方向に位置固定状態で嵌合接続されている。そして、排出用ケース５５の上下軸芯周りでの回動位置を変更操作する排出向き変更用の油圧シリンダ６５（以下、向き変更シリンダと略称する）が備えられている。 The discharge case 55 is fitted and connected to the main body case 53 so as to be relatively rotatable around the vertical axis Y1 and fixed in the vertical direction. A discharge direction changing hydraulic cylinder 65 (hereinafter, abbreviated as a direction changing cylinder) for changing the rotational position of the discharge case 55 around the vertical axis is provided.
　図１１に示すように、向き変更シリンダ６５は、支持フレーム５６に固定のブラケット６６と、排出用ケース５５に備えられたブラケット６７とに亘って設けられ、向き変更シリンダ６５を伸縮操作することで、排出用ケース５５が上下軸芯Ｙ１周りで回動して排出口５４の向きを変更することができる。従って、排出用ケース５５が本体ケース５３に対して上下軸芯Ｙ１周りで相対回動可能に支持される支持構造と、向き変更シリンダ６５とにより、油圧操作式の作動機構ＹＳとしての排出向き変更機構５２が構成される。 As shown in FIG. 11, the direction changing cylinder 65 is provided across a bracket 66 fixed to the support frame 56 and a bracket 67 provided in the discharge case 55, and the direction changing cylinder 65 is expanded and contracted. The discharge case 55 can be rotated around the vertical axis Y1 to change the direction of the discharge port 54. Accordingly, the discharge direction change as the hydraulically operated operation mechanism YS is performed by the support structure in which the discharge case 55 is supported so as to be rotatable relative to the main body case 53 around the vertical axis Y1 and the direction changing cylinder 65. A mechanism 52 is configured.
　図１１に示すように、左右両側の側壁部３３の上部に機体後部側に向けて片持ち状に延びる状態で固定アーム６８が連結されている。そして、支持フレーム５６の４本の支持アーム５７のうち、本体ケース５３の左右両側の横方向外端位置に設けられる２本の支持アーム５７の夫々が、本体ケース５３に対する連結箇所よりも下方に延設され、左右の固定アーム６８の後端部に横軸芯Ｘ２周りで回動可能に支持されている。従って、支持フレーム５６は分離装置７全体を支持するものであるから、分離装置７全体が横軸芯Ｘ２周りで回動可能に搬送装置６に支持されている。 As shown in FIG. 11, the fixed arm 68 is connected to the upper part of the left and right side wall portions 33 in a cantilevered manner toward the rear side of the machine body. Of the four support arms 57 of the support frame 56, each of the two support arms 57 provided at the laterally outer end positions on the left and right sides of the main body case 53 is below the connection location with respect to the main body case 53.
