Description

本発明は、耕耘作業やうね立て作業に用いられる車軸耕耘式の歩行型管理機に関する。   The present invention relates to an axle tillage type walking type management machine used for tillage work and ridge work.

機体から左右外側方に延出する車軸に、複数の耕耘爪を備える車軸耕耘式の歩行型管理機が知られている（例えば、特許文献１参照）。この種の歩行型管理機では、機体の後部に、圃場に接触して走行抵抗を発生させる抵抗棒が取付可能となっており、該抵抗棒が発生させる走行抵抗で走行速度を抑制することにより、所望の耕深が得られるようになっている。また、この種の歩行型管理機では、機体の後部にアタッチメントを装着することにより、通常の耕耘作業以外の作業も行うことが可能となっている。例えば、機体の後部に培土器を取り付ければ、耕耘と同時にうね立てを行うことが可能となる。   2. Description of the Related Art An axle tilling type walking type management machine is known that includes a plurality of tilling claws on an axle extending outward from left and right from the body (see, for example, Patent Document 1). In this type of walking-type management machine, a resistance bar that generates a running resistance by contacting the field can be attached to the rear part of the machine body, and the running speed is suppressed by the running resistance generated by the resistance bar. The desired tilling depth can be obtained. Further, in this type of walking type management machine, it is possible to perform work other than normal tillage work by attaching an attachment to the rear part of the machine body. For example, if a cultivator is attached to the rear part of the machine body, it becomes possible to ridge at the same time as plowing.

特開２００９−２０号公報Japanese Unexamined Patent Publication No. 2009-20

しかしながら、アタッチメントとして提供されている従来の培土器は、抵抗棒用の取付部（作業機連結ヒッチ）に取り付けるように構成されているので、作業種別を、通常の耕耘作業からうね立て作業に変更する場合や、うね立て作業から通常の耕耘作業に変更する場合に、抵抗棒と培土器の交換作業が必要となり、作業種別の変更に手間がかかるという問題があった。   However, the conventional earthenware provided as an attachment is configured to be attached to the resistance rod attachment (work machine connection hitch), so the work type is changed from normal tillage work to ridge work. When changing or when changing from a ridge work to a normal tillage work, it is necessary to replace the resistance bar and the earthenware, and there is a problem that it takes time to change the work type.

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、機体から左右外側方に延出する車軸に、複数の耕耘爪を備える車軸耕耘式の歩行型管理機であって、前記機体の後部に、圃場に接触して走行抵抗を発生させる抵抗棒用の取付部と、機体移動時に機体後部を支える移動尾輪用の取付部とを備え、該移動尾輪用の取付部を、移動尾輪を接地高さに保持する下降姿勢と、移動尾輪を非接地高さ保持する上昇姿勢とに回動変姿自在な移動尾輪ブラケットで構成すると共に、該移動尾輪ブラケットに、うね立て用の培土板を設けたことを特徴とする。
また、前記培土板は、移動尾輪ブラケットの回動に伴う抵抗棒との干渉を回避する切欠きを備えることを特徴とする。
また、前記培土板は、移動尾輪ブラケットを自由回動状態としたとき、耕深に応じて上下回動するリヤカバーとして機能することを特徴とする。 The present invention has been created in order to solve these problems in view of the above-described circumstances, and is an axle tillage type equipped with a plurality of tillage claws on an axle extending laterally outward from the body. It is a walking type management machine, and includes a mounting portion for a resistance rod that generates a running resistance in contact with a farm field, and a mounting portion for a moving tail wheel that supports the rear portion of the aircraft when moving, The mounting part for the moving tail wheel is composed of a moving tail wheel bracket that can be freely transformed into a lowered position for holding the moving tail wheel at a ground contact height and a rising position for holding the moving tail wheel at a non-ground height. In addition, the moving tail wheel bracket is provided with a ridged earth plate.
In addition, the culture plate is provided with a notch that avoids interference with the resistance rod accompanying the rotation of the movable tail wheel bracket.
In addition, the cultivating board functions as a rear cover that rotates up and down according to the tilling depth when the movable tail wheel bracket is in a freely rotating state.

請求項１の発明によれば、下降姿勢と上昇姿勢に回動変姿自在な移動尾輪ブラケットにうね立て用の培土板を設けたので、アタッチメントとして提供されている従来の培土器を使用することなく、うね立て作業を行うことができる。また、移動尾輪ブラケットを上昇させれば、培土板も上昇位置に退避させることができるので、培土板を取り外すことなく、通常の耕耘作業を行うことができる。
また、請求項２の発明によれば、培土板は、移動尾輪ブラケットの回動に伴う抵抗棒との干渉を回避する切欠きを備えるので、培土板と抵抗棒の干渉によって移動尾輪ブラケットの回動が阻害されることもない。
また、請求項３の発明によれば、培土板は、移動尾輪ブラケットを自由回動状態としたとき、耕深に応じて上下回動するリヤカバーとして機能するので、従来のリヤカバーを廃止し、コストダウンを図ることができる。 According to the first aspect of the present invention, since the grooving plate for ridges is provided on the movable tail wheel bracket that can be freely transformed into the lowered posture and the raised posture, the conventional cultivator provided as an attachment is used. It is possible to perform the ridge work without having to do so. Further, if the moving tail wheel bracket is raised, the cultivating plate can be retracted to the raised position, so that normal tilling work can be performed without removing the cultivating plate.
According to the invention of claim 2, the earth plate has a notch that avoids interference with the resistance bar accompanying the rotation of the moving tail wheel bracket, so that the moving tail wheel bracket is caused by the interference between the earth plate and the resistance bar. Is not obstructed.
Further, according to the invention of claim 3, the soil slab functions as a rear cover that rotates up and down in accordance with the tilling depth when the movable tail wheel bracket is in a freely rotating state, so the conventional rear cover is abolished, Cost can be reduced.

以下、本発明の実施の形態について、図面に基づいて説明する。まず、図１８及び図１９に示す従来例と共通する部分について、図１〜図３を参照して説明する。図１〜図３において、１は車軸耕耘式の歩行型管理機であって、該歩行型管理機１は、前後方向に沿う機体フレーム２を備え、該機体フレーム２の下側に、前低後高状に傾斜するチェンケース３が配置される一方、機体フレーム２の上側に、動力源であるエンジン４が搭載されている。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, portions common to the conventional example shown in FIGS. 18 and 19 will be described with reference to FIGS. In FIG. 1 to FIG. 3, reference numeral 1 denotes an axle tillage type walking type management machine. The walking type management machine 1 includes a body frame 2 extending in the front-rear direction, and a front lower portion is provided below the body frame 2. On the other hand, an engine 4 serving as a power source is mounted on the upper side of the machine body frame 2 while a chain case 3 that is inclined rearward is disposed.

エンジン４の左側面部には、エンジン４の動力をチェンケース３に伝達するベルト伝動機構（図示せず）と、これを覆うベルトカバー５が設けられている。また、エンジン４の上部には、ステー６を介して燃料タンク７が設けられると共に、燃料タンク７の周囲を覆うエンジンカバー８が設けられている。   A belt transmission mechanism (not shown) that transmits the power of the engine 4 to the chain case 3 and a belt cover 5 that covers the belt transmission mechanism are provided on the left side surface of the engine 4. A fuel tank 7 is provided on the upper portion of the engine 4 via a stay 6, and an engine cover 8 that covers the periphery of the fuel tank 7 is provided.

チェンケース３の下部には、エンジン動力で駆動される車軸９が設けられている。車軸９は、チェンケース３の下部から左右に延出しており、その中間部に複数の耕耘爪１０が設けられると共に、左右両端部にそれぞれ車輪１１が設けられている。   An axle 9 driven by engine power is provided at the lower part of the chain case 3. The axle 9 extends from the lower part of the chain case 3 to the left and right, a plurality of tilling claws 10 are provided at the middle part thereof, and wheels 11 are provided at both right and left ends.

本実施形態の車軸９は、チェンケース３に突設される固定車軸と、該固定車軸に着脱自在に設けられて軸長を延長する延長軸とを備えて構成されており、例えば、通常の耕耘作業時には、延長軸を取り付けて耕耘幅を広く確保する一方、中耕作業時には、延長軸を取り外して機体幅を狭くすることができるようになっている。   The axle 9 of the present embodiment includes a fixed axle protruding from the chain case 3 and an extension shaft that is detachably provided on the fixed axle and extends the axial length. At the time of tillage work, an extension shaft is attached to secure a wide tillage width, while at the time of middle tillage work, the extension shaft can be removed to narrow the body width.

また、チェンケース３の後端部には、作業機連結ヒッチ１２が一体的に設けられている。この作業機連結ヒッチ１２には、抵抗棒１３などの任意の作業機が装着されるようになっている。   Further, a work machine connection hitch 12 is integrally provided at the rear end portion of the chain case 3. An arbitrary work machine such as a resistance bar 13 is mounted on the work machine connection hitch 12.

さらに、チェンケース３の上端部には、ハンドルフレーム１４が突設されており、該ハンドルフレーム１４に左右のハンドル１５Ｌ、１５Ｒが設けられている。そして、左側のハンドル１５Ｌには、主クラッチレバー１６が設けられ、右側のハンドル１５Ｒには、スロットルレバー１７が設けられている。   Further, a handle frame 14 projects from the upper end portion of the chain case 3, and left and right handles 15 </ b> L and 15 </ b> R are provided on the handle frame 14. The left handle 15L is provided with a main clutch lever 16, and the right handle 15R is provided with a throttle lever 17.

エンジン４の下方には、機体の左右中心部から左右外側方に張り出して車軸９の基部上方を覆うフェンダ１８が設けられている。このフェンダ１８は、主として、耕耘爪１０によって跳ね上げられる泥や石が、耕耘爪１０の上方にあるエンジン４にかかることを防止するために設けたものであって、歩行型管理機１を運転する作業者の足元を保護するためには、車軸９の後方を覆うリヤカバー１９を設ける必要がある。そして、この種のリヤカバー１９は、耕深の変化などに追従するために、上端側を支点として上下回動自在であることが求められる。因みに、従来の歩行型管理機１００では、図１８及び図１９に示すように、作業機連結ヒッチ１２に回動支点部材１９ａを突設し、該固定支点部材１９ａでリヤカバー１９を回動自在に支持している。   A fender 18 is provided below the engine 4 so as to project outward from the left and right central portions of the fuselage to the left and right outer sides and cover the upper portion of the base portion of the axle 9. The fender 18 is provided mainly to prevent mud and stones that are lifted up by the tilling claws 10 from being applied to the engine 4 above the tilling claws 10. The fender 18 operates the walking type management machine 1. In order to protect the feet of the worker who performs, it is necessary to provide a rear cover 19 that covers the rear of the axle 9. The rear cover 19 of this type is required to be rotatable up and down with the upper end side as a fulcrum in order to follow changes in tilling depth and the like. Incidentally, in the conventional walking type management machine 100, as shown in FIGS. 18 and 19, a rotation fulcrum member 19a is projected from the work machine connection hitch 12, and the rear cover 19 can be rotated by the fixed fulcrum member 19a. I support it.

次に、本発明の実施形態に係る歩行型管理機１と、従来例に係る歩行型管理機１００との相違点、つまり、本発明の特徴的な構成について、図１〜図１７を参照して説明する。   Next, the difference between the walking type management machine 1 according to the embodiment of the present invention and the walking type management machine 100 according to the conventional example, that is, the characteristic configuration of the present invention will be described with reference to FIGS. I will explain.

図１〜図３に示すように、本発明の実施形態に係る歩行型管理機１は、機体移動時に機体後部を支える移動尾輪用の取付部として移動尾輪ブラケット２０を備えている。本実施形態の移動尾輪ブラケット２０は、左右一対の脚部２０ａを有する後面視冂字形状であり、左右脚部２０ａの下端部には、それぞれ、移動尾輪２１を回転自在に装着可能な尾輪装着部２０ｂが設けられている。また、移動尾輪ブラケット２０の上端部は、作業機連結ヒッチ１２に上下回動自在に連結されており、この回動にもとづいて、移動尾輪２１を接地高さに保持する下降姿勢と、移動尾輪２１を非接地高さ保持する上昇姿勢とに変姿することができるようになっている。   As shown in FIGS. 1 to 3, the walking management machine 1 according to the embodiment of the present invention includes a moving tail wheel bracket 20 as a mounting part for a moving tail wheel that supports the rear part of the body when the body moves. The moving tail wheel bracket 20 according to the present embodiment has a rear-view cross-sectional shape having a pair of left and right legs 20a, and a moving tail wheel 21 can be rotatably mounted on the lower ends of the left and right legs 20a. A tail wheel mounting portion 20b is provided. Further, the upper end portion of the movable tail wheel bracket 20 is connected to the work implement connecting hitch 12 so as to be rotatable up and down, and based on this rotation, a descending posture for holding the movable tail wheel 21 at the ground contact height, The moving tail wheel 21 can be transformed into an ascending posture that maintains a non-contact height.

移動尾輪ブラケット２０の基端部には、少なくとも上昇位置と下降位置で移動尾輪ブラケット２０の回動をロックする回動ロック手段２２が設けられている。本実施形態の回動ロック手段２２は、移動尾輪ブラケット２０と一体的に回動する左右一対のロックプレート２０ｃと、左右のロックプレート２０ｃを貫通する抜き挿し自在なロックピン２３とを備えて構成されており、ロックピン２３を作業機連結ヒッチ１２の孔１２ａに差し込むと、移動尾輪ブラケット２０が下降位置で回動ロックされ、また、ロックピン２３を作業機連結ヒッチ１２の後端部に当接させると、移動尾輪ブラケット２０が上昇位置で回動ロックされ、さらに、ロックピン２３を抜くと、移動尾輪ブラケット２０が自由回動するようになっている。尚、回動ロック手段２２は、図１〜図５に図示し、他の図では図示を省略する。   A rotation lock means 22 that locks the rotation of the moving tail wheel bracket 20 at least in the raised position and the lowered position is provided at the base end of the moving tail wheel bracket 20. The rotation lock means 22 of this embodiment includes a pair of left and right lock plates 20c that rotate integrally with the moving tail wheel bracket 20, and a lock pin 23 that can be inserted and removed through the left and right lock plates 20c. When the lock pin 23 is inserted into the hole 12a of the work implement connection hitch 12, the movable tail wheel bracket 20 is pivotally locked in the lowered position, and the lock pin 23 is connected to the rear end portion of the work implement connection hitch 12. The moving tail wheel bracket 20 is rotationally locked in the raised position, and when the lock pin 23 is removed, the moving tail wheel bracket 20 is freely rotated. The rotation lock means 22 is shown in FIGS. 1 to 5 and is not shown in other drawings.

移動尾輪ブラケット２０に装着される左右の移動尾輪２１は、作業の種類などに応じて、着脱したり、装着位置を変更することができるようになっている。例えば、図１〜図５は、尾輪装着部２０ｂの外側に移動尾輪２１を装着した状態を示し、図６〜図８は、尾輪装着部２０ｂの内側に移動尾輪２１を装着した状態を示している。   The left and right moving tail wheels 21 mounted on the moving tail wheel bracket 20 can be attached and detached and the mounting position can be changed according to the type of work. For example, FIGS. 1 to 5 show a state in which the moving tail wheel 21 is mounted on the outside of the tail wheel mounting portion 20b, and FIGS. 6 to 8 show that the moving tail wheel 21 is mounted on the inside of the tail wheel mounting portion 20b. Indicates the state.

移動尾輪ブラケット２０には、うね立て用の培土板２４を装着可能な培土板装着部２０ｄが設けられている。本実施形態の培土板装着部２０ｄは、左右の脚部２０ａを連結する連結部材２０ｅと、該連結部材２０ｅに突設される複数の装着ピン２０ｆとを備えて構成されており、培土板２４に形成される装着孔２４ａを装着ピン２０ｆに係合させることによって、培土板２４を移動尾輪ブラケット２０に装着することができるようになっている。このようにすると、下降姿勢と上昇姿勢に回動変姿自在な移動尾輪ブラケット２０にうね立て用の培土板２４を装着することができるので、アタッチメントとして提供されている従来の培土器を使用することなく、うね立て作業を行うことができる。また、移動尾輪ブラケット２０を上昇させれば、培土板２４も上昇位置に退避させることができるので、培土板２４を取り外すことなく、通常の耕耘作業を行うことができる。   The moving tail wheel bracket 20 is provided with a culture plate mounting portion 20d to which a ridge plate 24 can be mounted. The culture plate mounting portion 20d of the present embodiment includes a connecting member 20e that connects the left and right legs 20a and a plurality of mounting pins 20f that project from the connecting member 20e. By engaging the mounting hole 24a formed on the mounting pin 20f with the mounting pin 20f, the soil culturing plate 24 can be mounted on the moving tail wheel bracket 20. In this way, since the ridge plate 24 can be mounted on the movable tail wheel bracket 20 that can be freely transformed into a lowered posture and a raised posture, the conventional cultivator provided as an attachment can be mounted. Ridge work can be performed without using. Further, if the moving tail wheel bracket 20 is raised, the cultivating plate 24 can also be retracted to the raised position, so that normal tilling work can be performed without removing the cultivating plate 24.

具体的に説明すると、本実施形態の培土板２４は、図９に示すように、うねの谷部を形成すべく逆三角形状に形成されており、その中央上部には、装着ピン２０ｆに係合可能な二つの装着孔２４ａが形成されている。本実施形態の装着ピン２０ｆは、基部が小径で、頭部が大径な形状を有する一方、培土板２４の装着孔２４ａは、装着ピン２０ｆの頭部よりも大径な大径孔部と、装着ピン２０ｆの基部よりも大径で、かつ、頭部よりも小径な小径孔部とを連続的に有するひょうたん形状となっており、装着孔２４ａの大径孔部を装着ピン２０ｆに差し込んでから、培土板２４を下方にスライドさせることにより、装着孔２４ａの小径孔部が装着ピン２０ｆの頭部に抜止め状に係合されるようになっている。尚、本実施形態では、培土板２４を装着ピン２０ｆに対して係合状態で装着しているが、装着ピン２０ｆにＲピンなどの抜止め部材を装着するようにしてもよい。   More specifically, as shown in FIG. 9, the soil culturing plate 24 of the present embodiment is formed in an inverted triangle shape so as to form a ridge valley, and the mounting pin 20f is formed at the center upper portion thereof. Two mounting holes 24a that can be engaged are formed. The mounting pin 20f of the present embodiment has a shape with a small diameter base and a large diameter head, while the mounting hole 24a of the earth plate 24 has a large diameter hole portion larger in diameter than the head of the mounting pin 20f. The gourd shape has a small-diameter hole continuously larger than the base of the mounting pin 20f and smaller than the head, and the large-diameter hole of the mounting hole 24a is inserted into the mounting pin 20f. Then, the small-diameter hole portion of the mounting hole 24a is engaged with the head of the mounting pin 20f in a retaining manner by sliding the culture plate 24 downward. In the present embodiment, the soil culturing plate 24 is mounted in an engaged state with the mounting pin 20f, but a retaining member such as an R pin may be mounted on the mounting pin 20f.

また、本実施形態の培土板２４には、抵抗棒１３との干渉を回避するための孔２４ｂ又は切欠き２４ｃが形成されている。つまり、本実施形態の歩行型管理機１では、図１０などに示すように、培土板２４と抵抗棒１３の位置がオーバーラップするので、抵抗棒１３が貫通する孔２４ｂ又は切欠き２４ｃを培土板２４に形成している。   Further, the soil culture plate 24 of the present embodiment is formed with a hole 24b or a notch 24c for avoiding interference with the resistance bar 13. That is, in the walking type management machine 1 of the present embodiment, as shown in FIG. 10 and the like, the position of the cultivating plate 24 and the resistance bar 13 overlap, so that the hole 24b or the notch 24c through which the resistance bar 13 passes is formed as the cultivating medium. It is formed on the plate 24.

特に、図９の（Ｂ）、（Ｃ）に示すように、培土板２４の下端部まで到達する切欠き２４ｃとした場合には、移動尾輪ブラケット２０の回動に伴う抵抗棒１３との干渉を回避することができるので、培土板２４と抵抗棒１３の干渉によって移動尾輪ブラケット２０の回動が阻害されることがなく、その結果、移動尾輪ブラケット２０の回動操作に際して、培土板２４や抵抗棒１３の着脱を不要とし、作業性の向上が図れる。   In particular, as shown in FIGS. 9B and 9C, when the cutout 24c reaches the lower end of the soil culturing plate 24, the resistance rod 13 with the rotation of the moving tail wheel bracket 20 is used. Since the interference can be avoided, the rotation of the mobile tail wheel bracket 20 is not hindered by the interference between the soil culture plate 24 and the resistance bar 13, and as a result, when the mobile tail wheel bracket 20 is rotated, the culture medium is It is not necessary to attach or detach the plate 24 or the resistance rod 13, and workability can be improved.

また、培土板２４の下端部まで到達する切欠き２４ｃとする場合は、図９の（ｃ）に示すように、切欠き２４ｃを開閉自在に覆うゴム製のカバー２５を設けることが好ましい。このようにすると、切欠き２４ｃからの土の流出を最小限に抑えることができる。   Further, when the cutout 24c reaches the lower end of the soil culturing plate 24, as shown in FIG. 9C, it is preferable to provide a rubber cover 25 that covers the cutout 24c in an openable and closable manner. If it does in this way, the outflow of the soil from the notch 24c can be suppressed to the minimum.

培土板２４の寸法は、任意に設定することが可能であるが、培土板２４の下端が移動尾輪２１の下端よりも上方に位置するように寸法設定を行うことが好ましい。例えば、図１０に示すように、培土板２４の下端と移動尾輪２１の下端との間に寸法Ｇを確保する。このようにすると、移動尾輪２１を使用した機体移動に際し、培土板２４を地面から浮かせることができるので、機体移動が培土板２４によって阻害されることがないだけでなく、培土板２４の損傷も防止することができる。   Although the dimension of the cultivating plate 24 can be arbitrarily set, it is preferable to set the dimension so that the lower end of the cultivating plate 24 is located above the lower end of the moving tail wheel 21. For example, as shown in FIG. 10, the dimension G is secured between the lower end of the cultivating plate 24 and the lower end of the moving tail wheel 21. In this way, when the machine body using the moving tail wheel 21 is moved, the culture plate 24 can be floated from the ground, so that the machine movement is not hindered by the culture plate 24, and the culture plate 24 is damaged. Can also be prevented.

また、本実施形態の培土板２４（図９の（Ｂ）、（Ｃ）に示す培土板）は、リヤカバーとして機能させることができるようになっている。つまり、培土板２４を装着された移動尾輪ブラケット２０を自由回動状態として耕耘作業を行うと、培土板２４が耕深に応じて上下回動するリヤカバーとして機能することになる。これにより、従来のリヤカバーを廃止し、コストダウンを図ることができる。   In addition, the soil culturing plate 24 (the soil culturing plate shown in FIGS. 9B and 9C) of this embodiment can function as a rear cover. That is, when the tilling work is performed with the movable tail wheel bracket 20 to which the cultivating plate 24 is attached being freely rotated, the cultivating plate 24 functions as a rear cover that rotates up and down according to the tilling depth. Thereby, the conventional rear cover can be abolished and the cost can be reduced.

叙述の如く構成された本実施形態によれば、機体から左右外側方に延出する車軸９に、複数の耕耘爪１０を備える車軸耕耘式の歩行型管理機１であって、機体の後部に、圃場に接触して走行抵抗を発生させる抵抗棒１３用の取付部（作業機連結ヒッチ１２）と、機体移動時に機体後部を支える移動尾輪２１用の取付部とを備え、該移動尾輪２１用の取付部を、移動尾輪２１を接地高さに保持する下降姿勢と、移動尾輪２１を非接地高さ保持する上昇姿勢とに回動変姿自在な移動尾輪ブラケット２０で構成すると共に、該移動尾輪ブラケット２０に、うね立て用の培土板２４を設けたので、アタッチメントとして提供されている従来の培土器を使用することなく、うね立て作業を行うことができる。また、移動尾輪ブラケット２０を上昇させれば、培土板２４も上昇位置に退避させることができるので、培土板２４を取り外すことなく、通常の耕耘作業を行うことができる。   According to the present embodiment configured as described, an axle tiller-type walking management machine 1 having a plurality of tilling claws 10 on an axle 9 extending outward from the left and right sides of the aircraft, And a mounting portion for the resistance rod 13 (work machine connection hitch 12) for generating a running resistance in contact with the field, and a mounting portion for the moving tail wheel 21 that supports the rear of the body when the body is moved. The mounting portion for 21 is composed of a movable tail wheel bracket 20 that can be freely transformed into a lowered posture for holding the movable tail wheel 21 at a ground contact height and an elevated posture for holding the movable tail wheel 21 at a non-ground height. In addition, since the ridge plate 24 is provided on the movable tail wheel bracket 20, the ridge operation can be performed without using a conventional cultivator provided as an attachment. Further, if the moving tail wheel bracket 20 is raised, the cultivating plate 24 can also be retracted to the raised position, so that normal tilling work can be performed without removing the cultivating plate 24.

また、培土板２４は、移動尾輪ブラケット２０の回動に伴う抵抗棒１３との干渉を回避する切欠き２４ｃを備えるので、培土板２４と抵抗棒１３の干渉によって移動尾輪ブラケット２０の回動が阻害されることもない。   Further, since the culture plate 24 includes a notch 24c that avoids interference with the resistance bar 13 due to the rotation of the movable tail wheel bracket 20, the rotation of the mobile tail wheel bracket 20 due to the interference between the culture plate 24 and the resistance bar 13 is provided. The movement is not hindered.

また、培土板２４は、移動尾輪ブラケット２０を自由回動状態としたとき、耕深に応じて上下回動するリヤカバーとして機能するので、従来のリヤカバーを廃止し、コストダウンを図ることができる。   Moreover, since the cultivating plate 24 functions as a rear cover that rotates up and down in accordance with the tilling depth when the movable tail wheel bracket 20 is in a freely rotating state, the conventional rear cover can be eliminated and the cost can be reduced. .
