Description

本発明は、耕耘爪に関する。   The present invention relates to a tilling nail.

従来、耕耘爪を用いて内盛耕耘及び外盛耕耘を行う管理機の技術は公知である（例えば、特許文献１）。
特許文献１に記載の管理機は、耕耘爪による耕耘土の移動方向を内盛側と外盛側の間で切り換えて、内盛耕耘・外盛耕耘の切り換えを行うときには、爪軸を付け替えて、耕耘爪の先端の向きを変える必要があった。そして、爪軸を付け替える際に、爪軸を固定するためのピンの抜き差しを行わなければならなかった。 Conventionally, the technique of the management machine which performs inner-side tillage and outer-side tillage using a tilling nail is publicly known (for example, patent documents 1).
When the management machine described in Patent Document 1 switches the moving direction of the cultivated soil by the tilling claw between the inner and outer embankment sides and switches between the inner and outer tilling, the nail shaft is changed. It was necessary to change the direction of the tip of the tilling nail. And when changing a nail | claw axis | shaft, the pin for fixing a nail | claw axis | shaft had to be inserted / removed.

しかし、爪軸の付け替えを行う際には、前記ピンの向きを間違えないように注意しながら作業を行わなければならなかったり、泥のついた耕耘爪を扱わなければならなかったりして、作業が面倒であった。また、ピンが変形していたときには、爪軸の付け替えが困難になるおそれがあった。これにより、内盛耕耘・外盛耕耘の切り換えを行う際に手間がかかることがあった。   However, when changing the nail axis, work must be done with care not to make a mistake in the direction of the pin, or the mud tilling nail must be handled. Was troublesome. Further, when the pin is deformed, it may be difficult to replace the claw shaft. This sometimes takes time when switching between inner and outer tillage.

Yes. The attachment bases 21L and 21R of the tilling claws 20L and 20R are respectively attached to the attachment flanges 18L and 18R of the claw shaft 16 with bolts, nuts, etc., and rotate integrally with the claw shaft 16.

耕耘爪２０Ｌ・２０Ｒの正回転時の打込み側部分２２Ｌ・２２Ｒ、及び逆回転時の打込み側部分２４Ｌ・２４Ｒの内の、一方の打込み側部分２２Ｌ・２２Ｒの内側面には、内側湾曲面２３Ｌ・２３Ｒがそれぞれ形成されており、他方の打込み側部分２４Ｌ・２４Ｒの外側面には、外側湾曲面２５Ｌ・２５Ｒがそれぞれ形成されている。   Of the driving side portions 22L and 22R when the tilling claws 20L and 20R are rotated forward and the driving side portions 24L and 24R during the reverse rotation, the inner curved surface 23L 23R is formed, and outer curved surfaces 25L and 25R are formed on the outer surfaces of the other driving side portions 24L and 24R, respectively.

図３（ａ）、図４、図５（ａ）、及び図６に示すように、内側湾曲面２３Ｌ・２３Ｒは、一方の打込み側部分２２Ｌ・２２Ｒの内側面（機体１０の幅方向Ｗ内側の面）に形成されている。内側湾曲面２３Ｌ・２３Ｒは、取付基部２１Ｌ・２１Ｒ側から先端に向かうに伴って機体１０の幅方向Ｗ内側、すなわち機体１０の左右中央側（ミッションケース１１側）に向かうように湾曲する形状を有している。
また、内側湾曲面２３Ｌ・２３Ｒは、正回転方向下流側に向かうに従い、すなわち、一方の打込み側部分２２Ｌ・２２Ｒから打ち込まれるときの回転方向下流側に向かうに従い、機体１０の幅方向Ｗ内側に傾く形状を有している。 As shown in FIGS. 3A, 4, 5 A and 6, the inner curved surfaces 23 </ b> L and 23 </ b> R are the inner side surfaces of the one driving side portions 22 </ b> L and 22 </ b> R (the inner side in the width direction W of the machine body 10). Formed on the surface). The inner curved surfaces 23L and 23R have a shape that curves toward the inner side in the width direction W of the fuselage 10, that is, toward the left and right center side (mission case 11 side) of the fuselage 10 as it goes from the attachment bases 21L and 21R to the tip. Have.
Further, the inner curved surfaces 23L and 23R are arranged on the inner side in the width direction W of the airframe 10 as they go to the downstream side in the normal rotation direction, that is, toward the downstream side in the rotation direction when driven from one of the driving side portions 22L and 22R. It has an inclined shape.

図３（ｂ）、図４、図５（ｂ）、及び図６に示すように、外側湾曲面２５Ｌ・２５Ｒは、他方の打込み側部分２４Ｌ・２４Ｒの外側面（機体１０の幅方向Ｗ外側の面）に形成されている。外側湾曲面２５Ｌ・２５Ｒは、取付基部２１Ｌ・２１Ｒ側から先端に向かうに伴って機体１０の幅方向Ｗ外側、すなわち機体１０の左右外側に向かうように湾曲する形状を有している。
また、外側湾曲面２５Ｌ・２５Ｒは、逆回転方向下流側に向かうに従い、すなわち、他方の打込み側部分２４Ｌ・２４Ｒから打ち込まれるときの回転方向下流側に向かうに従い、機体１０の幅方向Ｗ外側に傾く形状を有している。 As shown in FIGS. 3B, 4, 5B, and 6, the outer curved surfaces 25L and 25R are the outer surfaces of the other driving side portions 24L and 24R (the outer side in the width direction W of the fuselage 10). Formed on the surface). The outer curved surfaces 25L and 25R have a shape that curves toward the outer side in the width direction W of the fuselage 10, that is, toward the left and right outer sides of the fuselage 10 as it goes from the attachment bases 21L and 21R to the tip.
Further, the outer curved surfaces 25L and 25R are arranged on the outer side in the width direction W of the fuselage 10 toward the downstream side in the reverse rotation direction, that is, toward the downstream side in the rotation direction when driven from the other driving side portions 24L and 24R. It has an inclined shape.

なお、内側湾曲面２３Ｌ・２３Ｒと、外側湾曲面２５Ｌ・２５Ｒは互いに対象（湾曲角度が同一）である必要はなく、作業状況等に応じて湾曲角度に差を有していてもよい。   Note that the inner curved surfaces 23L and 23R and the outer curved surfaces 25L and 25R do not need to be objects (the same bending angle), and may have a difference in the bending angle depending on the work situation or the like.

図３（ａ）〜図６に示すように、耕耘爪２０Ｌ・２０Ｒの正回転時の打込み側部分２２Ｌ・２２Ｒと、逆回転時の打込み側部分２４Ｌ・２４Ｒと、の間には略平板状の中間部分２６Ｌ・２６Ｒが一体的に設けられている。耕耘爪２０Ｌ・２０Ｒは、中間部分２６Ｌ・２６Ｒを設けることで、耕耘爪の体積を確保して、強度を確保している。   As shown in FIGS. 3A to 6, a substantially flat plate is formed between the driving side portions 22 </ b> L and 22 </ b> R during forward rotation of the tilling claws 20 </ b> L and 20 </ b> R and the driving side portions 24 </ b> L and 24 </ b> R during reverse rotation. Intermediate portions 26L and 26R are integrally provided. The tilling claws 20L and 20R are provided with intermediate portions 26L and 26R, thereby securing the volume of the tilling claws and securing the strength.

図３（ａ）、図５（ａ）、及び図７（ａ）に示すように、耕耘爪２０Ｌ・２０Ｒの正回転時には、耕耘爪２０Ｌ・２０Ｒの打込み側部分２２Ｌ・２２Ｒから土壌に打ち込まれる。このとき、打込み側部分２２Ｌ・２２Ｒの内側湾曲面２３Ｌ・２３Ｒは、耕耘土５０をすくって、そして、すくった耕耘土５０を機体１０の幅方向Ｗ内側（内盛側）に向かって移動させる（飛ばす）こととなる。
従って、耕耘爪２０Ｌ・２０Ｒを正回転させることによって、耕耘爪２０Ｌ・２０Ｒの内側湾曲面２３Ｌ・２３Ｒにより耕耘土５０を機体１０の幅方向Ｗ内側（内盛側）に向かって移動させて、内盛耕耘を行い、内盛りの畝を成形することが可能となる。 As shown in FIGS. 3 (a), 5 (a), and 7 (a), when the tilling claws 20L and 20R are rotated forward, they are driven into the soil from the driving side portions 22L and 22R of the tilling claws 20L and 20R. . At this time, the inner curved surfaces 23L and 23R of the driving side portions 22L and 22R scoop the cultivated soil 50 and move the scooped cultivated soil 50 toward the inner side (inner side) in the width direction W of the body 10. (Skip).
Therefore, by rotating the tilling claws 20L and 20R in the forward direction, the tilling soil 50 is moved toward the inner side in the width direction W (inner side) of the body 10 by the inner curved surfaces 23L and 23R of the tilling claws 20L and 20R. It is possible to mold the inner paddy by performing the inner paddy cultivation.

図３（ｂ）、図５（ｂ）、及び図７（ｂ）に示すように、耕耘爪２０Ｌ・２０Ｒの逆回転時には、耕耘爪２０Ｌ・２０Ｒの打込み側部分２４Ｌ・２４Ｒから土壌に打ち込まれる。このとき、打込み側部分２４Ｌ・２４Ｒの外側湾曲面２５Ｌ・２５Ｒは、耕耘土５０をすくって、そして、すくった耕耘土５０を機体１０の幅方向Ｗ外側（外盛側）に向かって移動させる（飛ばす）こととなる。
従って、耕耘爪２０Ｌ・２０Ｒを逆回転させることによって、耕耘爪２０Ｌ・２０Ｒの外側湾曲面２５Ｌ・２５Ｒにより耕耘土５０を機体１０の幅方向Ｗ外側（外盛側）に向かって移動させて、外盛耕耘を行い、外盛りの畝を成形することが可能となる。 As shown in FIG. 3 (b), FIG. 5 (b), and FIG. 7 (b), when the tilling claws 20L and 20R are reversely rotated, they are driven into the soil from the driving side portions 24L and 24R of the tilling claws 20L and 20R. . At this time, the outer curved surfaces 25L and 25R of the driving side portions 24L and 24R scoop the cultivated soil 50 and move the scooped cultivated soil 50 toward the outer side in the width direction W of the body 10 (on the outer side). (Skip).
Accordingly, by rotating the tilling claws 20L and 20R in reverse, the tilling soil 50 is moved toward the outer side in the width direction W of the body 10 (on the outer side) by the outer curved surfaces 25L and 25R of the tilling claws 20L and 20R. It is possible to form an externally built ridge by performing an externally cultivated plow.

以上のように構成することで、耕耘爪２０Ｌ・２０Ｒの回転方向を変更することで、耕耘爪２０Ｌ・２０Ｒによる耕耘土の移動方向を、機体１０の幅方向Ｗ内側（内盛側）と、機体１０の幅方向Ｗ外側（外盛側）の間で切り換えることが可能となる（図８参照）。従って、耕耘土の移動方向を内盛側と外盛側の間で円滑に切り替えることが可能となる。   By configuring as described above, by changing the rotation direction of the tilling claws 20L and 20R, the moving direction of the tilled soil by the tilling claws 20L and 20R is changed to the width direction W inner side (inner side) of the body 10, and It is possible to switch between the width direction W outer side (external side) of the airframe 10 (see FIG. 8). Therefore, it becomes possible to smoothly switch the moving direction of the cultivated soil between the inner filling side and the outer filling side.

なお、耕耘爪２０Ｌ・２０Ｒを左右逆に配置してもよい。すなわち、ミッションケース１１の左側に耕耘爪２０Ｒを配置して、ミッションケース１１の右側に耕耘爪２０Ｌを配置してもよい。
この場合、耕耘爪２０Ｌ・２０Ｒを正回転させることによって、内側湾曲面２３Ｌ・２３Ｒにより耕耘土を外盛側に向かって移動させることとなる。また、耕耘爪２０Ｌ・２０Ｒを逆回転させることによって、外側湾曲面２５Ｌ・２５Ｒにより耕耘土を内盛側に向かって移動させることとなる。 In addition, you may arrange | position the tilling claws 20L and 20R right and left. That is, the tilling claw 20R may be arranged on the left side of the mission case 11 and the tilling claw 20L may be arranged on the right side of the mission case 11.
In this case, by rotating the tilling claws 20L and 20R in the forward direction, the tilling soil is moved toward the outer side by the inner curved surfaces 23L and 23R. Further, by reversely rotating the tilling claws 20L and 20R, the tilled soil is moved toward the inner side by the outer curved surfaces 25L and 25R.

図９（ａ）〜図１０（ｂ）は、耕耘爪２０Ｌ・２０Ｒの変形例である耕耘爪４０Ｌ・４０Ｒを示す斜視図である。
図９（ａ）〜図１０（ｂ）に示すように、耕耘爪４０Ｌ・４０Ｒは、管理機（耕耘作業機）１に取り付けられた状態で、正回転時の打込み側部分、及び逆回転時の打込み側部分の内の、一方の打込み側部分の内側面には、取付基部４１Ｌ・４１Ｒ側から先端に向かうに伴って管理機１の機体１０の幅方向Ｗ内側に向かうように湾曲する内側湾曲面４３Ｌ・４３Ｒが形成され、他方の打込み側部分の外側面には、取付基部４１Ｌ・４１Ｒ側から先端に向かうに伴って機体１０の幅方向Ｗ外側に向かうように湾曲する外側湾曲面４５Ｌ・４５Ｒが形成される。耕耘爪４０Ｌ・４０Ｒは、耕耘爪２０Ｌ・２０Ｒに比べて外周面の起伏が滑らかに形成されている。
耕耘爪２０Ｌ・２０Ｒに替えて耕耘爪４０Ｌ・４０Ｒを採用した場合でも、耕耘爪２０Ｌ・２０Ｒを採用したときと同様の効果を奏する。 Fig.9 (a)-FIG.10 (b) are the perspective views which show the cultivation claws 40L * 40R which are the modifications of the cultivation claws 20L * 20R.
As shown in FIGS. 9 (a) to 10 (b), the tilling claws 40L and 40R are attached to the management machine (cultivating work machine) 1 and are driven in the forward rotation and in the reverse rotation. The inner surface of one of the driving side portions is curved so as to bend toward the inner side in the width direction W of the body 10 of the management machine 1 from the mounting base portion 41L / 41R side toward the tip. Curved surfaces 43L and 43R are formed, and an outer curved surface 45L that curves toward the outer side in the width direction W of the fuselage 10 as it goes from the mounting base 41L and 41R side to the distal end on the outer surface of the other driving side portion. -45R is formed. The tilling claws 40L and 40R have smoother undulations on the outer peripheral surface than the tilling claws 20L and 20R.
Even when the cultivation claws 40L and 40R are employed instead of the cultivation claws 20L and 20R, the same effects as when the cultivation claws 20L and 20R are employed are produced.

なお、図１１（ａ）〜図１１（ｃ）に示すように、耕耘爪４０Ｌ・４０Ｒに関しては、取付基部４１Ｌａ・４１Ｒａを、耕耘爪４０Ｌ・４０Ｒの外周面の延びる方向に略沿った平板形状に形成して、爪軸１６の取付フランジ１８Ｌａ・１８Ｒａを、爪軸１６の軸線αに対して傾けて配置してもよい。   As shown in FIGS. 11 (a) to 11 (c), regarding the tilling claws 40L and 40R, the mounting base portions 41La and 41Ra are formed in a flat plate shape substantially along the extending direction of the outer peripheral surface of the tilling claws 40L and 40R. The attachment flanges 18La and 18Ra of the claw shaft 16 may be inclined with respect to the axis α of the claw shaft 16.

なお、耕耘爪２０Ｌ・２０Ｒ・４０Ｌ・４０Ｒが取り付けられる耕耘作業機は管理機１に限定されず、例えば、トラクタに連結されて牽引されるロータリ耕耘装置であってもよい。   Note that the tilling work machine to which the tilling claws 20L, 20R, 40L, and 40R are attached is not limited to the management machine 1, and may be, for example, a rotary tiller that is connected to a tractor and pulled.
