There is. Therefore, attach the tiller claw to the Jt small claw holder with the bolt.
As a support structure for tilling claws that can be supported without using a fastening member such as a nut, for example, there is a support structure for tilling claws of a pinching support type (14J). A tilling claw holder is formed with an inclined wall in which the interval between the inner walls becomes narrower toward the first and second sides, and the tilling claw holder is fitted into the tilling claw holder,
Both 9i: consist of 411 Km claws formed symmetrically with inclined surfaces that become smaller in width. , the M1 claw hole and the plowing claw are connected by a support pin that passes through them. When the tilling shaft is rotated, the tilling claws receive the soil tilling reaction force, the sloped surface of the tilling claws bites into the inclined wall of the interest paying claw holder (wedge effect), and the M1 tilling claws are pressed against the tilling claw holder. Fixed and supported.

対の方向に回転される。Therefore, without removing the tilling claw from the tilling claw holder, it is necessary to hit the blade of the tilling claw with a hammer in the direction opposite to the reaction force of the soil book 11 to release the pinched state. Therefore, if the blade part of the tilling claw is struck as strongly as possible in the opposite direction, it will be rotated in the opposite direction with respect to the small tiller claw holder.
このため耕耘爪は耕耘爪ホルダに挟圧されて、再び耕耘
爪ホルダに固定・支持されることになる。For this reason, the tilling claw is compressed by the tilling claw holder, and is again fixed and supported by the tilling claw holder.

あった。Therefore, in order to remove the tiller, it is necessary to remove the tiller.
The problem is that the tiller claws must be struck with an appropriate force in the direction of the tillage reaction force, and the removal of the tiller claws is complicated and cannot be done easily.

いない。In the figure, 11 is a tilling shaft of a tiller, and a plurality of tilling claw holders 12 each having a substantially rectangular cross section are fixed to the tilling shaft 11 by welding at predetermined intervals in the axial direction. As shown in FIG. 2, the tilling claw holder 12 is made of a set of large and small plate parts U13a and 13b, each having a U-shaped cross section, whose center lines coincide with each other in the direction of rotation, and which are fitted together and fixed by welding. It's Otsu's. Slanted surfaces 14 are formed at the upper and lower ends of the larger plate member 13a so that the interval between the inner walls becomes narrower toward both ends. A convex portion 15 is formed in the center of the smaller plate-like member 13 toward the inside. A base end portion 17 of a tilling claw 16 having a substantially rectangular cross section is inserted into the tilling claw holder 12, and the T, $Q5 portion 17 and the tilling claw holder 12 are connected by four pins 18 passing through them. The glue end portion 17 of the tilling claw 16 bulges the proximal end side (C1d side in FIG. 1) of the side wall facing the plate-like member 13a in the direction of rotation of the tilling claw 16 (in the direction of the arrow in FIG. 1). It is press molded to make it look like it is installed. Therefore, point a in FIG. 1 is in contact with the inner wall surface of the plate member 13a, but point b is not in contact with this inner wall surface. Further, the distal end side (C1d side in FIG. 1) of the base end 17 of the tilling claw 16 is suppressed so as to bulge in the direction of the soil tillage reaction force (direction of arrow B in FIG. 1). . For this reason, in FIG. 1 (one point is the plate member 13
It is in contact with the inner wall surface of point a, but point 0 is not in contact with this inner wall surface.

る。When the tiller is operated, the tiller shaft 11 is rotated counterclockwise in the counterclockwise direction, and as the tiller shaft 11 is rotated, the ROM pawl 16c) is rotated counterclockwise. This rotating tilling claw 1G comes into contact with 1- and raises the soil, but due to the reaction force received from the soil at this time, 1) the tilling claw 1G
The base end portion 17 of is rotated in the direction of 51 o'clock around the bin 18 within the tilling claw holder 12. When the base end 17 is rotated in the rotating direction, the raised points a and d of the base end 17 are pressed inward by the inclined surface 14 of the tilling claw holder 12, and at this time, the base Since the end portion 17 is also pressed by the convex portion 15 of the tilling claw holder 12, the base end portion 17 is twisted as a whole. Therefore, the base end portion 17 is twisted by the inclined surface 14 and the convex portion 15, and is firmly fixed and supported by the tilling claw holder 14.

ると、耕耘爪１６のａ。Next, in order to remove the tilling claw 16 attached to the tilling claw holder 12, the tip of the tilling claw 16 is struck with a hammer to rotate the tilling claw 16 in a direction around the opposite portion 81 around the bin 18. When the tilling claw 16 is rotated in the direction around the opposite arm 1, the a of the tilling claw 16.
ｄ点は１１耘爪ホルダ１２の傾斜面１４に押圧されなく
なり、耕耘爪ホルダ１２はねじり状態から解除される。Point d is no longer pressed by the inclined surface 14 of the plowing claw holder 12, and the tilling claw holder 12 is released from the twisted state.

However, since this point c does not touch this inclined surface 14, it is not pressed by this inclined surface 14, and the M1 plowing claw 1G is twisted again and fixed and supported by the tilling claw boulder 12, so that it does not become C. . Therefore, Jul
The small plowing claws can be easily and easily removed from the tilling claw holder 12 by hitting them with a hammer or the like.

When the tilling claw is rotated in the opposite direction, the twisted state is released and the tilling claw can be removed from the tilling claw holder, so the fixed and supported tilling claw can be removed with a hammer or the like. Even if the tilling claw is struck and rotated in the opposite direction to the -I direction, the tilling claw will not be twisted again and fixed/supported by the tilling claw holder.Therefore, in order to remove the tilling claw from the tilling claw holder, This step 2 can be performed simply and easily by hitting it once with a hammer or the like.
