Description

本発明は、農作業等を行うための小型乗用作業機に関する。   The present invention relates to a small riding work machine for performing farm work or the like.

従来、小型乗用作業機の一形態として、自走可能な走行車体の後方に連結機構を介して各種作業装置を連結可能としたものがある（例えば、特許文献１参照。）。   Conventionally, as a form of small riding work machine, there is one in which various work devices can be connected to a rear of a self-propelled traveling vehicle body via a connecting mechanism (see, for example, Patent Document 1).

そして、かかる小型乗用作業機は、特に、小規模の圃場において農作業機等として利用されているが、収穫物等を運搬ないしは搬出する機能を有していない。   Such a small riding work machine is used as an agricultural work machine or the like particularly in a small-scale field, but does not have a function of carrying or carrying a harvested product or the like.

そのため、圃場内にて収穫した収穫物等を、圃場外に停車させている動力運搬車、例えば、軽量トラックまで搬出する作業は、一輪車や小規模の圃場内でも小回りのきく専用の動力搬出車を利用している。   For this reason, a power carrier that stops the harvested items, etc., harvested in the field to the outside of the field, for example, to a light truck, is a dedicated power unloading vehicle that can be used even in a unicycle or a small field. Is used.

ところが、一輪車の場合、圃場内から圃場外に停車させている軽量トラックまで収穫物等を人力により運搬するために、大きな労力を要する上に、一輪車と軽量トラックの荷台との間に高低差がある場合には、一輪車から軽量トラックの荷台へ収穫物等を人力により移し替えなければならないために、これまた大きな労力を要するという不具合がある。   However, in the case of a unicycle, it takes a lot of labor to manually transport the harvested items from the field to the light truck stopped outside the field, and there is a difference in height between the unicycle and the platform of the light truck. In some cases, it is necessary to manually transfer the harvest from the unicycle to the platform of the light truck.

また、専用の動力搬出車の場合、収穫物等を搬出するのに労力を要しない半面、かかる動力搬出車を用意すること自体にコストがかかるという不具合がある上に、専用の動力搬出車の荷台と軽量トラックの荷台との間に高低差がある場合には、一輪車と同様に、専用の動力搬出車の荷台から軽量トラックの荷台へ収穫物等を人力により移し替えなければならないために、大きな労力を要するという不具合がある。   In addition, in the case of a dedicated power delivery vehicle, while it does not require labor to carry out harvested items etc., there is a problem that it is costly to prepare such a power delivery vehicle itself, If there is a difference in height between the loading platform and the loading platform of the light truck, as with a unicycle, the harvest etc. must be transferred manually from the loading platform of the dedicated power truck to the loading platform of the lightweight truck. There is a problem that requires a lot of labor.

そこで、例えば、特許文献２に開示されたトラクタのように、連結機構にリフト装置を装着して、同リフト装置により収穫物等を運搬することも考えられる。
特開平１１−２４３７１０号公報 実開昭６３−１７５６９５号公報 Therefore, for example, like a tractor disclosed in Patent Document 2, it is conceivable that a lift device is attached to the coupling mechanism and a harvested product or the like is transported by the lift device.
Japanese Patent Laid-Open No. 11-243710 Japanese Utility Model Publication No. 63-175695

しかしながら、連結機構に連結されている各種作業装置に替えてリフト装置を連結する際の付け替え作業に手間を要するという不具合がある。   However, there is a problem in that it takes time to perform the replacement work when connecting the lift device in place of the various work devices connected to the connection mechanism.

しかも、かかるリフト装置は、リフト装置をチルトさせるための大型のチルト用油圧シリンダを具備しているために、装置自体が大型化しており、特に、小規模の圃場内においては、その取り扱い性が悪く、構造も複雑化して、製造コストが高くなるという不具合がある。   In addition, since the lift device includes a large tilt hydraulic cylinder for tilting the lift device, the size of the device itself is increased. In particular, in a small-scale field, the lift device is easy to handle. Unfortunately, the structure is complicated and the manufacturing cost increases.

そこで、本発明では、自走可能な走行車体の後方に連結機構を介して各種作業装置を連結可能とした小型乗用作業機において、走行車体の前端部に取付機構を介してリフト装置を取り付けると共に、同取付機構は、走行車体に取り付ける走行車体側取付体と、同走行車体側取付体に左右方向の軸線廻りにチルト作動自在に連結したリフト装置側取付体と、同リフト装置側取付体をチルト作動させる手動式チルト作動手段と、同手動式チルト作動手段に連動連結したチルト操作手段とを具備することを特徴とする小型乗用作業機を提供するものである。   Therefore, in the present invention, in a small riding work machine in which various working devices can be connected to the rear of a self-propelled traveling vehicle body via a connection mechanism, a lift device is attached to the front end portion of the traveling vehicle body via an attachment mechanism. The mounting mechanism includes a traveling vehicle body-side attachment body that is attached to the traveling vehicle body, a lift device-side attachment body that is connected to the traveling vehicle body-side attachment body so as to be tiltable about a horizontal axis, and the lift device-side attachment body. Provided is a small riding work machine comprising a manual tilt actuating means for tilting operation, and a tilt operating means interlockingly connected to the manual tilt actuating means.

A small riding work machine comprising a manual tilt actuating means for tilting the lifted object support body with respect to the ascending / descending moving body, and a tilt operating means linked to the manual tilt actuating means. Is to provide.

そして、本発明は、運転部は、リフト装置の直後方に位置する走行車体上の前部に配設し、同運転部の近傍にチルト操作手段を配置したことにも特徴を有する。   The present invention is also characterized in that the operating unit is disposed at a front portion on the traveling vehicle body located immediately after the lift device, and a tilt operation means is disposed in the vicinity of the operating unit.

本発明によれば、以下のような効果が得られる。   According to the present invention, the following effects can be obtained.

（１）請求項１記載の本発明では、自走可能な走行車体の後方に連結機構を介して各種作業装置を連結可能とした小型乗用作業機において、走行車体の前端部に取付機構を介してリフト装置を取り付けると共に、同取付機構は、走行車体に取り付ける走行車体側取付体と、同走行車体側取付体に左右方向の軸線廻りにチルト作動自在に連結したリフト装置側取付体と、同リフト装置側取付体をチルト作動させる手動式チルト作動手段と、同手動式チルト作動手段に連動連結したチルト操作手段とを具備している。   (1) According to the first aspect of the present invention, in a small riding work machine in which various working devices can be connected to the rear of a self-propelled traveling vehicle body via a connection mechanism, the front end portion of the traveling vehicle body is provided with an attachment mechanism.

このようにして、走行車体の前端部に取付機構を介してリフト装置を取り付けているため、走行車体の後方に連結機構を介して連結している各種作業装置との付け替え作業を必要とせず、各種作業装置による農作業等と、リフト装置による収穫物等の搬出作業とを連続的にないしは同時に行うことができる。   In this way, since the lift device is attached to the front end portion of the traveling vehicle body via the attachment mechanism, no replacement work with various work devices connected to the rear of the traveling vehicle body via the connection mechanism is required, Agricultural work or the like by various work devices and unloading work of harvested goods or the like by a lift device can be performed continuously or simultaneously.

そして、リフト装置は、圃場外に停車させている動力運搬車まで収穫物等の搬出作業を行うことができると共に、同動力運搬車の荷台の高さまで収穫物等を上昇させることができるため、同収穫物等を動力運搬車の荷台へ楽に移し替えることができる。   And the lift device can carry out the harvesting work etc. up to the power carrier stopped outside the field, and can raise the harvest etc. to the height of the loading platform of the power carrier, The harvests can be easily transferred to the platform of a powered vehicle.

しかも、リフト装置は、手動式チルト作動手段を具備して、同手動式チルト作動手段をチルト操作手段によりチルト操作することができるようにしているため、リフト装置自体を小型化することができ、特に、小規模の圃場内においては、その取り扱い性がよく、構造も簡易化して、製造コストも安価なものとなすことができる。   In addition, since the lift device includes manual tilt actuating means, and the manual tilt actuating means can be tilted by the tilt operating means, the lift device itself can be reduced in size, In particular, in a small-scale field, the handleability is good, the structure is simplified, and the manufacturing cost can be reduced.

（２）請求項２記載の本発明では、走行車体の前端部にリフト装置を取り付けると共に、同リフト装置は、走行車体の前端部に立設した昇降案内枠体と、同昇降案内枠体に昇降移動自在に取り付けた昇降移動体と、同昇降移動体に取り付けて被昇降物を支持する被昇降物支持体と、同被昇降物支持体に昇降移動体を介して連動連結して、同被昇降物支持体を昇降させる手動式昇降手段とを具備し、昇降移動体と被昇降物支持体との間に、同被昇降物支持体を昇降移動体に対してチルト作動させる手動式チルト作動手段と、同手動式チルト作動手段に連動連結したチルト操作手段とを設けている。   (2) In the present invention according to claim 2, the lift device is attached to the front end portion of the traveling vehicle body, and the lift device is installed on the elevation guide frame body standing on the front end portion of the traveling vehicle body, and the elevation guide frame body. The lifting / lowering movable body attached to the lifting / lowering movement body, the lifting / lowering object support attached to the lifting / lowering movement body to support the object to be lifted, A manual tilting means for manually lifting and lowering the lifted object support, and for tilting the lifted object support with respect to the lifted movable body between the lifted moving object and the lifted object support Actuating means and tilt operating means linked to the manual tilt actuating means are provided.

このようにして、昇降移動体と被昇降物支持体との間に、同被昇降物支持体を昇降移動体に対してチルト作動させる手動式チルト作動手段と、同手動式チルト作動手段に連動連結したチルト操作手段とを設けているため、チルト操作手段を操作して、手動式チルト作動手段を作動させることにより、被昇降物支持体を昇降移動体に対してチルト作動させることができる。   In this way, manual tilt operating means for tilting the lifted object support body with respect to the lift moving body between the lift moving body and the lifted object support body, and interlocking with the manual tilt actuating means. Since the connected tilt operation means is provided, the object support body can be tilted with respect to the ascending / descending moving body by operating the tilt operation means and operating the manual tilt operation means.

この際、リフト装置全体をチルトさせる手動式チルト作動手段に比べて、被昇降物支持体を昇降移動体に対してチルト作動させる手動式チルト作動手段の方が、チルト操作量を少なくすることができる。   At this time, the manual tilt actuating means for tilting the object support body with respect to the ascending / descending moving body may reduce the amount of tilt operation compared to the manual tilt actuating means for tilting the entire lift device. it can.

従って、手動式チルト作動手段を小型化することができて、機体の軽量化を図ることができる。   Therefore, the manual tilt actuating means can be reduced in size, and the weight of the airframe can be reduced.

本実施の形態では、リフト装置側取付体57に昇降案内枠体90を取り付けた状態においては、昇降案内体95が、運転部３の直前方位置にて走行車体Ｂの左右幅中心線上に位置するようにしている。   In the present embodiment, in a state where the lifting guide frame body 90 is attached to the lifting device side attachment body 57, the lifting guide body 95 is positioned on the left and right width center line of the traveling vehicle body B at a position immediately before the driving unit 3. Like to do.

従って昇降案内体95に被昇降物支持体92の左右中心位置を整合させておくことにより、同被昇降物支持体92の左右側前方伸延支持片113,113に被昇降物を支持させる際に、両前方伸延支持片113,113と被昇降物の左右中心位置合わせを容易に行うことができる。その結果、被昇降物の昇降作業を効率良く行うことができる。   Therefore, by aligning the left and right center position of the object support body 92 with the elevating guide body 95, both the left and right front extension support pieces 113, 113 of the object object support body 92 can be It is possible to easily align the left and right centers of the front extension support pieces 113 and 113 and the object to be lifted. As a result, it is possible to efficiently lift and lower the object.

また、回動操作ハンドル151は、回動支軸152への基端部の取り付け位置を調節自在とすることにより、同回動操作ハンドル151の回動半径を適宜調節して、リフト装置Ｆの構成部材と干渉しないようにすることができる。   Further, the rotation operation handle 151 can adjust the rotation radius of the rotation operation handle 151 appropriately by making the attachment position of the base end portion to the rotation support shaft 152 adjustable. It is possible not to interfere with the structural member.

本実施の形態に係る小型乗用作業機Ａでは、オペレータＭは、圃場内にて収穫した収穫物等の被昇降物を被昇降物支持体92に支持させ、同状態にて走行車体Ｂを走行移動させることにより、リフト装置Ｆによる収穫物等の搬出作業を安全にかつ確実に行うことができる。   In the small riding work machine A according to the present embodiment, the operator M causes the object support body 92 to support the object to be lifted such as the harvested product in the field, and travels the traveling vehicle body B in the same state. By moving it, it is possible to safely and reliably carry out the harvested product and the like by the lift device F.

そして、所要の場所、例えば、動力運搬車の荷台の近傍位置に停車させて、手動式昇降手段93を昇降操作手段94を介して手動操作することにより、被昇降物支持体92を昇降移動体91を介して昇降案内枠体90に沿わせて動力運搬車の荷台の高さまで上昇させることができて、被昇降物支持体92に支持させた被昇降物である収穫物等を動力運搬車の荷台へ楽に移し替えることができる。   Then, the object support body 92 is moved up and down by stopping at a required place, for example, in the vicinity of the loading platform of the power carrier and manually operating the manual lifting means 93 via the lifting operation means 94. It is possible to raise the height of the loading platform of the power carrier along the lifting guide frame 90 through 91, and the harvested goods that are the materials to be lifted and supported by the workpiece support 92 are powered trucks. It can be easily transferred to the loading platform.

この際、昇降案内枠体90が昇降案内体95と左右一対の補強体96,96とを具備しているため、簡易な構造にして昇降案内枠体90の強度を良好に確保することができると共に、左右一対の補強体96,96が被昇降物の荷受部材としても機能し、同被昇降物を円滑かつ確実に昇降させることができる。   At this time, since the lifting guide frame 90 includes the lifting guide body 95 and the pair of left and right reinforcing bodies 96, 96, the strength of the lifting guide frame 90 can be ensured with a simple structure. At the same time, the pair of left and right reinforcing bodies 96 function as a load receiving member for the object to be lifted, and the lifted object can be raised and lowered smoothly and reliably.

しかも、補強体96,96に、昇降案内体95の上部より左右外側方へ伸延する左右一対の外側方伸延片100,100と、各外側方伸延片100,100の外側端部より下方へ向けて伸延する左右一対の下方伸延片101,101とを具備させ、左右一対の外側方伸延片100,100は、ハンドル25の把持部よりも低位置に配置しているため、同ハンドル25の把持部を把持して操向操作を行うオペレータＭにとって、前方視界性を良好に確保することができる。   In addition, the reinforcing bodies 96, 96 have a pair of left and right outer extending pieces 100, 100 extending from the upper part of the lifting guide body 95 to the left and right outer sides, and left and right extending downward from the outer ends of the outer extending pieces 100, 100. Since the pair of left and right outer extending pieces 100, 100 are arranged at a lower position than the gripping portion of the handle 25, the steering operation is performed by gripping the gripping portion of the handle 25. For the operator M who performs the above, it is possible to ensure good front visibility.

The harvest can be easily transferred to the platform of a powered vehicle.

しかも、リフト装置Ｆは、手動式昇降手段93を具備して、同手動式昇降手段93を昇降操作手段94により昇降操作することができるようにしているため、リフト装置Ｆ自体を小型化することができ、特に、小規模の圃場内においては、その取り扱い性がよく、構造も簡易化して、製造コストも安価なものとなすことができる。   In addition, since the lift device F includes the manual lifting / lowering means 93 so that the manual lifting / lowering means 93 can be lifted / lowered by the lifting / lowering operating means 94, the lift device F itself can be downsized. In particular, in a small-scale field, the handling is good, the structure is simplified, and the manufacturing cost can be reduced.

さらには、昇降操作手段94は、走行車体Ｂ上に配設した運転部３の近傍に配置しているため、オペレータＭは、運転部３の座席27に着座した状態にて、走行車体Ｂを操向操作しながらでも楽に昇降操作手段94を操作することができ、効率良く収穫物等の搬出作業を行うことができる。   Further, since the lifting operation means 94 is disposed in the vicinity of the driving unit 3 disposed on the traveling vehicle body B, the operator M moves the traveling vehicle body B while sitting on the seat 27 of the driving unit 3. The lift operation means 94 can be easily operated even during the steering operation, and the harvesting work etc. can be carried out efficiently.

この際、オペレータＭは、前方のリフト装置Ｆを視認しながら昇降操作手段94を操作することができるため、搬出作業能率と搬出作業時の安全性とを良好に確保することができる。   At this time, the operator M can operate the elevating operation means 94 while visually confirming the lift device F in front, so that the carrying-out work efficiency and the safety during the carrying-out work can be ensured satisfactorily.

しかも、昇降操作手段94を着座操作位置(イ)と起立操作位置(ロ)との間で位置変更自在となしているため、オペレータＭは、作業条件等に応じて所要の位置にて楽に昇降操作手段94を手元操作することができる。   Moreover, since the elevating operation means 94 is freely changeable between the seating operation position (A) and the standing operation position (B), the operator M can easily move up and down at a required position according to work conditions and the like. The operating means 94 can be operated at hand.

従って、リフト装置Ｆによる収穫物等の搬出作業を効率良く行うことができる。   Therefore, it is possible to efficiently carry out the harvested work and the like by the lift device F.

また、昇降操作手段94を操作しない場合には、収納位置(ロ)に配置しておくことにより、同昇降操作手段94が他物等に干渉して損傷等されるのを防止することができる。特に、格納庫等に走行車体Ｂを格納する際には、格納スペースのコンパクト化を図ることができる。   Further, when the lifting operation means 94 is not operated, it is possible to prevent the lifting operation means 94 from being damaged due to interference with other objects and the like by arranging it in the storage position (b). . In particular, when the traveling vehicle body B is stored in a hangar or the like, the storage space can be made compact.

I try to do it.

チルト作動手段58は、図１２及び図１３に示すように、第１変容例のチルト作動手段58と同様に構成しており、リフト装置側取付体57の一部を形成するリフト装置取付片171の後面中途部に左右一対の作動体連結ブラケット160,160を取り付けて、両作動体連結ブラケット160,160間に、左右方向に軸線を向けた連結ピン161を介してチルト作動体155の前端部を枢支・連結する一方、走行車体側取付体56の上部に左右一対の偏芯コマ連結ブラケット162,162を取り付けて、両偏芯コマ連結ブラケット162,162間に、偏芯軸157を介して偏芯コマ156を枢支・連結している。   As shown in FIGS. 12 and 13, the tilt actuating means 58 is configured in the same manner as the tilt actuating means 58 of the first modification, and a lift device mounting piece 171 that forms a part of the lift device side mounting body 57. A pair of left and right operating body connecting brackets 160, 160 are attached to the middle part of the rear surface. On the other hand, a pair of left and right eccentric piece connecting brackets 162, 162 are attached to the upper portion of the traveling vehicle body side mounting body 56, and the eccentric piece 156 is pivotally supported between the eccentric piece connecting brackets 162, 162 via an eccentric shaft 157.・ Consolidated.

チルト操作手段59は、図１２及び図１３に示すように、上記偏芯軸157の右側端部にギヤケース176を介して下端部を連動連結すると共に、上端部を後上方へ向けて伸延させて形成した回動シャフト177と、同回動シャフト177の上端部に取り付けて、ハンドル25の下方近傍に配置した回動式のチルト操作ハンドル178とを具備している。179はシャフト支持体である。   As shown in FIGS. 12 and 13, the tilt operating means 59 is connected to the right end portion of the eccentric shaft 157 via the gear case 176, and the upper end portion is extended rearward and upward. A rotation shaft 177 formed, and a rotation type tilt operation handle 178 attached to the upper end portion of the rotation shaft 177 and disposed near the lower portion of the handle 25 are provided. Reference numeral 179 denotes a shaft support.

このようにして、ハンドル25を左手で把持したまま、右手でチルト操作ハンドル178を正回転方向（例えば、時計廻り）に回動させて、回動シャフト177を介して偏芯軸1 57を正回転方向に回動させることにより、図１２の実線で示す状態から一点鎖線で示す状態にチルト調節することができる一方、同チルト操作ハンドル178を逆回転方向（例えば、反時計廻り）に回動させて、回動シャフト177を介して偏芯軸157を逆回転方向に回動させることにより、図１２の一点鎖線で示す状態から実線で示す状態に復元調節することができるようにしている。   In this manner, while holding the handle 25 with the left hand, the tilt operation handle 178 is rotated in the forward rotation direction (for example, clockwise) with the right hand, and the eccentric shaft 157 is moved forward through the rotation shaft 177. By rotating in the rotation direction, it is possible to adjust the tilt from the state shown by the solid line in FIG. 12 to the state shown by the alternate long and short dash line, while rotating the tilt operation handle 178 in the reverse rotation direction (for example, counterclockwise). Thus, by rotating the eccentric shaft 157 in the reverse rotation direction via the rotation shaft 177, it is possible to restore and adjust the state shown by the one-dot chain line in FIG. 12 to the state shown by the solid line.

この際、図１２の一点差線で示すように、チルト操作ハンドル178を正回転方向に回動させると、偏芯軸157を介して偏芯コマ156が図１２の側面視にて反時計廻りに回動され、同偏芯コマ156の中心位置が偏芯軸157よりも前方へ移動されて、チルト作動体155を介してリフト装置側取付体57が前傾姿勢に姿勢変更されるようにしている。   At this time, as shown by a one-dot difference line in FIG. 12, when the tilt operation handle 178 is rotated in the forward rotation direction, the eccentric piece 156 is rotated counterclockwise in the side view of FIG. So that the center position of the eccentric piece 156 is moved further forward than the eccentric shaft 157 and the posture of the lift device side mounting body 57 is changed to the forward tilted posture via the tilt operating body 155. ing.

その結果、リフト装置側取付体57に取り付けたリフト装置Ｆの昇降案内体95も前傾姿勢に姿勢変更されて、被昇降物支持体92の前方伸延支持片113を、図１２の一点鎖線で示すように、前方へ向けて下り傾斜状態に姿勢変更することができる。   As a result, the lift guide body 95 of the lift device F attached to the lift device side attachment body 57 is also changed to the forward tilted posture, and the front extension support piece 113 of the lifted object support body 92 is indicated by a one-dot chain line in FIG. As shown, the posture can be changed to a downwardly inclined state toward the front.

しかも、前方伸延支持片113の下り傾斜角度は、チルト操作ハンドル178の正回転方向への回動操作量に応じて任意に設定することができる。   Moreover, the downward inclination angle of the front extension support piece 113 can be arbitrarily set according to the amount of rotation operation of the tilt operation handle 178 in the forward rotation direction.

従って、被昇降物や作業状況等に応じて、チルト操作ハンドル178の回動操作量を変更して、前方伸延支持片113の下り傾斜姿勢を任意に変更することにより、確実にかつ効率良く被昇降物を昇降させることができる。   Therefore, the amount of rotation of the tilt operation handle 178 is changed in accordance with the object to be lifted and the work situation, and the downward inclination posture of the front extension support piece 113 is arbitrarily changed, so that the cover can be reliably and efficiently covered. The elevator can be raised and lowered.
