のとされている。This foreign object remover 20 is removably attached to the side frame 6.7, which is a fixed frame that rotatably supports the tilling shaft 12, with bolts 22, etc., but in this embodiment, as shown in FIG. The mounting portion 20b is stacked on the inner surface of the fixed frame so that the longitudinal direction of the mounting portion 20b is in the vertical direction and a space is created that penetrates in the front-rear direction between the side frame 6.7, which is a fixed frame, and the tenant body 20a. They are also attached with bolts 22, and furthermore, they are attached so that at least a part of the borrowing body 20a of the foreign object remover 20 is located close to the adjacent pawl 13 and within the pawl rotation trajectory, and here, The band longitudinal edge portion 20C of the borrowing body 20a has a fixed blade function.

なお、第２図で示す如く取付は孔２１はその一方を異物

耘・枠上作業が実施される。According to the specific example of the present invention configured as described above, when the drive-type tilling machine A is towed by a tractor and the power is transmitted to the tilling part B consisting of the claws 13 and the tilling shaft 12, the tilling shaft 12 is rotated horizontally and horizontally around its axis, and plowing and work on the frame are carried out.

、異物排除具２０の借主体２０ ａ特にその帯長手側縁
部分２０ Ｃと爪１３との相対移動にて摺擦されて爪１
３より外れ、絡みを防止する。If there is long foreign matter such as grass or straw during this tilling work, the nail 1
3, the object 20a of the foreign object remover 20 is moved around with its longitudinal direction in the vertical direction, and at least a part of the object 20a is brought close to the claw 13, and , since it is provided on the fixed side of the claw rotation locus, it is rubbed by the relative movement of the claw 13 and the borrowing body 20a of the foreign object remover 20, especially the longitudinal side edge portion 20C of the band, and the claw 1
3 to prevent tangling.

特に、異物排除具２０はその借主体２０ａ、と固定枠と

主体２０ ａが弾性変形を容易とするので異物の量にか
かわりなく効果的に排除することになるし、借主体２０
ａに異物が絡らんでもこれが前記空間りによる弾性容
易さにより振動することとなって落下排除される。In particular, since the foreign matter remover 20 has a space formed between its borrowing body 20a and the fixed frame, the borrowing body 20a easily deforms elastically during the sliding contact, so that the amount of foreign matter is not affected. This would effectively eliminate the debtor 20
Even if a foreign object becomes entangled in a, it will vibrate due to the elasticity of the space and will fall and be removed.

更に、異物排除具２０の借主体２０ ａが上下方向とし
て固定枠に取付けであるから借主体２０ ａの帯長手側
縁部分２０ Ｃが所謂固定刃となり所謂回転刃となる爪
１３との協働で長尺異物を切断することとなり、この切

なり、更に、切断された細い異物は空間りを介して逃が
されるのである。Furthermore, since the main body 20a of the foreign object remover 20 is attached to the fixed frame in the vertical direction, the longitudinal side edge portion 20C of the main body 20a becomes a so-called fixed blade and cooperates with the claw 13, which becomes a so-called rotary blade. The long foreign object will be cut with
The band width of 0 H becomes the front-back direction and fully opposes each other, and furthermore, the cut thin foreign matter escapes through the space.

従って、異物の絡みが成長するのを防止することによっ
て、軸受手段１０．１１のオイルシールを痛めたりする
ことがないし、耕耘軸１２への絡みも防止して作業性が
良好となる。Therefore, by preventing the foreign matter from growing, the oil seal of the bearing means 10.11 is not damaged, and the foreign matter is also prevented from becoming entangled with the tiller shaft 12, resulting in improved workability.

また、異物排除具２０の所謂固定刃機能を有する帯長手
側縁部分２０ Ｃを鋭利形状にすることによって前記異
物の切断機能を促進できる。Moreover, by making the band longitudinal side edge portion 20C, which has a so-called fixed blade function, of the foreign matter remover 20 into a sharp shape, the foreign matter cutting function can be promoted.

本考案は爪と隣接しかつ爪の回転軌跡内に少なくとも一
部が位置する異物排除具の借主体を固定枠との間に空間
を造成して固定枠に取付けたので、借主体が所謂固定刃
で爪が所謂回転刃の機能を奏して長尺異物を切断して細
かくし絡みを防止できる。In the present invention, the borrowing body of the foreign object remover, which is adjacent to the claw and at least partially located within the rotation trajectory of the claw, is attached to the fixed frame with a space created between the fixed frame and the borrowing body is fixed. The claws of the blade function as a so-called rotary blade to cut long foreign objects into smaller pieces and prevent them from becoming tangled.

また、前記借主体はその長手方向を上下方向として固定
枠に取付けているから、前記切断機能を効果的に発揮で
きるし、切断抵抗にも充分対抗できる。Furthermore, since the borrowing body is attached to the fixed frame with its longitudinal direction facing up and down, it can effectively perform the cutting function and can sufficiently resist cutting resistance.

更に、弾性材料からなる異物排除具の借主体は固定枠と
の間に空間を有するので、異物の量に係りなく前記切断
機能を発揮し、かつ弾性変形を容易とするので異物を効
果的に払い落すことができる。Furthermore, since the main body of the foreign matter remover made of an elastic material has a space between it and the fixed frame, it can perform the cutting function regardless of the amount of foreign matter, and it can be easily elastically deformed, so it can effectively remove foreign matter. It can be brushed off.

なお、図面第３図、第４図を参照すると、耕耘爪１３に
工夫を施した場合が図解されている。In addition, referring to FIGS. 3 and 4 of the drawings, a case where the tilling claws 13 are modified is illustrated.

なお、第３，４図にも上記した本考案は採用できる。Note that the present invention described above can also be applied to FIGS. 3 and 4.

耘時に刃縁部１３Ｈに引掛った草・藁等を土中に埋設す
る。In Figures 3 and 4, a saw blade-shaped uneven curved surface is formed on the blade edge 13a of the tilling claw 13 attached to the tilling shaft 12, and grass, straw, etc. caught on the blade edge 13H during tilling are removed from the soil. to be buried.

つまり、刃縁部１３ａの凹凸曲面１３ｂに異物が引掛っ
て刃１３が第４図では反時計針方向に回転していると、

方に摺動されて土中に埋設され、これらが肥料となる。In other words, if a foreign object gets caught on the uneven curved surface 13b of the blade edge 13a and the blade 13 rotates counterclockwise in FIG.
Grass and the like are slid outward in the radial direction by the resistance force against the tilling force shown by the arrows and buried in the soil, which becomes fertilizer.
