次に車輪１７と培土板Ｂの構成について図４と図５に基づいて説明する。
培土板Ｂは背面視で逆台形状に形成する平面の鉄板で、左右両端に後方に向かって屈曲する屈曲部２２を形成している。また、上部の左右中央には切欠き部２３を形成し、該切欠き部２３には中割れするゴム板２４を取りつける構成としている。 Next, the structure of the wheel 17 and the cultivating board B will be described with reference to FIGS.
The cultivating plate B is a flat iron plate formed in an inverted trapezoidal shape when viewed from the back, and has bent portions 22 that are bent rearward at both left and right ends. Further, a notch 23 is formed in the upper left and right center, and a rubber plate 24 that is to be cracked is attached to the notch 23.

左右一対の車輪１７はそれぞれ培土板Ｂの下部の左右両端部の後方に対向する位置に設け、それぞれ支持体２５で支持される構成である。左右の支持体２５は横軸芯の回動軸２６で連結し、回動軸２６が回動すると左右の支持体２５及び車輪１７が共に前後方向に回動する構成である。   The pair of left and right wheels 17 are provided at positions facing the rear of the left and right end portions of the lower part of the cultivating plate B, and are each supported by the support body 25. The left and right support bodies 25 are connected by a horizontal axis rotation shaft 26, and when the rotation shaft 26 rotates, both the left and right support bodies 25 and the wheels 17 rotate in the front-rear direction.

培土板Ｂは支持体２５に連結して左右の車輪１７及び支持体２５と共に回動する構成で、支持体２５の上部と培土板Ｂの上部とを連結する上部連結板３０と、支持体２５の下部と培土板Ｂの下部とを連結する下部連結板３１とで連結する構成である。上部連結板３０は一端を培土板Ｂに固着し、他端を支持体２５にピンで固定し、支持体２５に対して横軸芯に回動自在に構成している。   The cultivating board B is connected to the support body 25 and is rotated together with the left and right wheels 17 and the supporting body 25. The upper connecting plate 30 that connects the upper part of the supporting body 25 and the upper part of the cultivating board B, and the supporting body 25. It connects with the lower connection board 31 which connects the lower part of this, and the lower part of the cultivation board B. As shown in FIG. One end of the upper connecting plate 30 is fixed to the culture plate B, the other end is fixed to the support body 25 with a pin, and the upper connection plate 30 is configured to be rotatable about the horizontal axis with respect to the support body 25.

下部連結板３１は培土板Ｂ側に固着する固定部３１ａと、支持体２５側に連結する調節部３１ｂとで構成し、固定部３１ａと調節部３１ｂとはリンク動作可能に連結すると共に、調節部３１ｂには長孔３１ｄを形成して培土板Ｂの下部と車輪１７との前後方向の距離を変更する構成である。   The lower connecting plate 31 includes a fixing portion 31a that is fixed to the culture plate B side and an adjusting portion 31b that is connected to the support body 25. The fixing portion 31a and the adjusting portion 31b are connected to each other so that the link operation is possible. A long hole 31d is formed in the portion 31b to change the distance in the front-rear direction between the lower portion of the culture plate B and the wheel 17.

支持体２５の回動軸２６の外周を回動軸２６を支持する中空状の回動支持軸３２で覆い、回動支持軸３２の外周には後機体フレーム２１側に固定する固定具３５と、位置合わせ孔２７ａを形成した位置合わせプレート２７を取り付けている。また、回動軸２６側には側面視扇形で複数個所の位置決め孔ｍ、ｎ、ｐを形成した位置決めプレート３３を取り付けている。そして、位置決めピン３４で位置決め孔ｍ、ｎ、ｐのいずれかと位置合わせ孔２７ａを合わせて挿入し、支持体２５、すなわち車輪１７と培土板Ｂの位置を培土作業位置、運搬作業位置、耕耘作業位置に変更する構成である。   The outer periphery of the rotation shaft 26 of the support body 25 is covered with a hollow rotation support shaft 32 that supports the rotation shaft 26, and the outer periphery of the rotation support shaft 32 is fixed to the rear body frame 21 side. The alignment plate 27 in which the alignment holes 27a are formed is attached. In addition, a positioning plate 33 having a plurality of positioning holes m, n, and p in a fan shape in a side view is attached to the rotating shaft 26 side. Then, the positioning pin 34 is inserted into the positioning hole m, n, or p with the alignment hole 27a, and the position of the support 25, that is, the wheel 17 and the soil culturing board B is determined as the culturing work position, the transporting work position, and the tilling work. It is the structure which changes to a position.

次に耕耘しながら畝を形成する培土作業と、非耕耘時の歩行型耕耘機を移動する運搬作業と、通常の耕耘作業について説明する。
培土作業時（図１及び図５の（ロ）参照）は培土板Ｂと車輪１７との距離が広くなる位置に調節部３１ｂを調節して固定ボルト３１ｃで位置固定する。位置決めピン３４を培土作業位置孔ｍと位置合わせ孔２７ａに挿入して支持体２５を斜め後姿勢として車輪１７を接地すると、培土板Ｂが支持体２５より急傾斜の斜め後姿勢となり下端部が培土作用時に圃場Ｈに作用する姿勢となる。そして、作業者が操作ハンドル１３を把持して耕耘部Ｋの回転による推進力で圃場を耕耘し、耕耘した土を培土板Ｂの前面で受けて左右両側に押し出し、屈曲部２２の面で案内及び押圧することで左右に畝の傾斜面を形成する。このとき、車輪１７は耕耘深さを一定になるように調節する役割を果たしている。また、培土作業時には抵抗棒１８は不要なので横ホルダ２０に前後方向長手姿勢に収納し、運転操作および培土作業いずれにも邪魔しないようにしている。 Next, the cultivation work for forming the ridge while plowing, the transporting work for moving the walking type tiller during non-plowing, and the normal cultivating work will be described.
At the time of cultivating work (see FIGS. 1 and 5 (B)), the adjusting portion 31b is adjusted to a position where the distance between the cultivating plate B and the wheel 17 is widened, and the position is fixed by the fixing bolt 31c. When the positioning pin 34 is inserted into the culturing work position hole m and the alignment hole 27a and the wheel 17 is grounded with the support body 25 in an obliquely rearward posture, the cultivating board B becomes an obliquely rearward posture that is steeper than the support body 25, and the lower end portion is It becomes the posture which acts on the field H at the time of soil cultivation. Then, the operator holds the operation handle 13 and cultivates the field with the propulsive force generated by the rotation of the cultivating part K, receives the cultivated soil on the front surface of the cultivating board B, pushes it out to the left and right sides, and guides it on the surface of the bent part 22 And the inclined surface of a ridge is formed on the right and left by pressing. At this time, the wheel 17 plays a role of adjusting the tilling depth to be constant. In addition, since the resistance rod 18 is not necessary during the culturing work, it is stored in the lateral holder 20 in the longitudinal direction in the longitudinal direction so as not to disturb both the operation and the culturing work.

運搬作業時（図２及び図５の（イ）参照）には、培土板Ｂと車輪１７との距離が狭くなる位置に調節部３１ｂを調節して固定ボルト３１ｃで位置固定する。位置決めピン３３を運搬作業位置孔ｎと位置合わせ孔２７ａに挿入して、支持体２５を地面に対して急傾斜又は略垂直の姿勢にして車輪を接地すると、培土板Ｂが斜め前姿勢となって圃場から非作用位置まで上方に離間する。また、運転者が操作ハンドル１３を押し下げると、耕耘部Ｋも地面から離間し、機体前側が斜め上向きになり、機体が運搬姿勢となる。このとき、培土板Ｂは耕耘爪６の耕耘回転軌跡Ｇ内に入らない構成としている。   At the time of carrying work (see (a) in FIGS. 2 and 5), the adjusting portion 31b is adjusted to a position where the distance between the soil culturing plate B and the wheel 17 becomes narrow, and the position is fixed by the fixing bolt 31c. When the positioning pin 33 is inserted into the transporting work position hole n and the alignment hole 27a, and the wheel is grounded with the support body 25 being steeply inclined or substantially perpendicular to the ground, the cultivating board B is in a slanting front position. And away from the field to the non-acting position. Further, when the driver depresses the operation handle 13, the tillage part K is also separated from the ground, the front side of the body is inclined upward, and the body is in the transporting posture. At this time, the cultivating board B is configured not to enter the tillage rotation locus G of the tillage claw 6.

通常の耕耘作業時（図３及び図５の（ハ）参照）は車輪１７と培土板Ｂは不要のため上方に回動して位置決めピン３３を耕耘作業位置孔ｐと位置合わせ孔２７ａに挿入して支持体２５を後斜め上姿勢にする。そして、抵抗棒１８を縦ホルダー１９で縦方向長手姿勢に保持し、下端部を圃場面Ｈに作用させる。このとき、抵抗棒１８は培土板Ｂの切欠き部２３のゴム板２４の中割れ部を貫通する構成である。   During normal tillage work (see (c) in FIGS. 3 and 5), the wheel 17 and the cultivating board B are unnecessary, so that they rotate upward and the positioning pin 33 is inserted into the tillage work position hole p and the alignment hole 27a. Then, the support body 25 is set to the rear obliquely upward posture. Then, the resistance rod 18 is held in the vertical longitudinal posture by the vertical holder 19, and the lower end is applied to the field scene H. At this time, the resistance rod 18 is configured to penetrate through the middle crack portion of the rubber plate 24 of the cutout portion 23 of the culture plate B.

そして、作業者が操作ハンドル１３を把持して耕耘部Ｋの回転の推進力で耕耘作業がなされる。   Then, the operator grips the operation handle 13 and performs the tilling work with the driving force of the rotation of the tilling portion K.
