うにしたらのが知られている。To attach the T-11 plow claw to a holder provided on the tillage shaft, the base is attached and removed.In order to install the plow claw, in general, an insertion hole is bored in the holder and the base of the tiller in a direction perpendicular to the direction of rotation. A bolt is inserted into this insertion hole and fixed by tightening with a nut. However, tillage claws are used in the soil, and when replacing tillage claws, if the bolts and nuts are rusted or not tightly tightened, removing them is troublesome, and many This is a problem that requires a lot of effort and time. In order to solve this problem, for example, as disclosed in Japanese Utility Model Publication No. 47-9603, the tilling claws are attached by fitting the base into a holder provided on the tilling shaft, and drilling holes into the holder and the tilling claws. It is known that a claw pin is inserted into the inserted hole, and the claw pin is pressed by a spring plate member to prevent it from coming out.

When this tilling claw is attached to a holder using a conventional tilling claw, the spring plate member presses the head of the claw pin and the claw pin does not easily come off from the holder, making it safe. The plate member does not come off from the holder, so there is no chance of losing it.Furthermore, when removing the tiller claw from the holder, it can be easily removed by simply rotating the spring plate member, and the operation of attaching and detaching the tiller claw is simple and short. It can be done in time. [Examples] Examples of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 is a rotating shaft of a 17-tary plowing device or a rotary raking device, and a boulder 2 is fixed to this plowing shaft 1 in the radial direction. The base of the tilling claw 3 is detachably attached. The holder 2 has its base end fixed to the tilling claw 1 by welding, and the f!!! end side is open. to form a claw base insertion hole 2a,
A claw pin insertion hole 2 that passes through this claw base insertion hole 2a from side to side and has a hexagonal shape on one side and a circular shape with a smaller diameter on the other side.
b is formed. A claw pin 4 shown in detail in FIGS. 5 and 6 is inserted into the claw pin insertion hole 2b with the base of the tilling claw 3 inserted into the claw base insertion hole 2a. The claw pin 4 consists of a hexagonal head 4a and pins # and 4b, and an engaging protrusion 4C is formed on the hexagonal head 4a. The engagement protrusion 4C may be formed in the engagement recess. A base end portion of a spring plate 5, which will be described later, is pivotally attached to one side surface of the holder 2 via a pivot pin 6. As shown in FIG. 3 and FIG. 1, the spring plate 5 has a pin insertion hole 5a bent in a U-shape from the rotating plate portion 5b on the base side to form a pressing portion 5C, and a pressing portion 5C on the tip side thereof. An engagement recess 5d that engages and presses the engagement protrusion 4C of the claw pin 4 is formed. This engaging recess 5d may be formed into an engaging protrusion. In the apparatus for installing the tiller claw with such a configuration, when attaching the υ1 tiller claw 3 to the holter 2, move the spring plate 5 clockwise around the pivot pin 6 as shown by the imaginary line in FIG. To install the tilling claws 3, insert the base into the claw base insertion hole 2a, insert the claw pin 4 into the claw pin insertion hole 2b, and rotate the spring plate 5 counterclockwise as shown by the solid line in FIG. When the engaging recess 5d is rotated in the direction shown in FIG.
It engages with the engaging protrusion 4C and presses the head to prevent it from coming off. Further, the spring plate 5 is located on the rear side with respect to the rotational direction of the tilling shaft 1. By rotating the tilling shaft 1 in the direction of the arrow in FIG. 1, the tilling claws 3 perform tilling or plowing work. When the M claw 3 is not removed from the boulder 2, apply an impact to the spring plate 5 by an appropriate means and rotate the spring plate 5 clockwise in FIG. The engagement recess 5d of the spring plate 5 is disengaged, the claw pin 4 is removed from the claw pin insertion hole 2b, and the tilling claw 3 can be attached by removing the base from the claw base insertion hole 2a. Therefore, it can be removed easily and in a short time. The rotation of the spring plate 5 can be performed by tapping the edge of the spring plate 5 with a suitable person, but it may also be performed by preparing a special jig. [Effects of the Invention] As explained above, depending on the device, the ↑j1 claw attachment of the present invention pivots one end of the spring plate member to the holder side.
To prevent a spring plate member from coming off a bolt, to prevent the scale from being lost, and to facilitate the rotational movement of the spring plate member to ensure a holding effect. Therefore, it is possible to securely prevent the pawl pin from coming out, and work can be performed safely; and; 1; the υI pawl can be easily attached to and removed from the rudder; Also, the spring plate member is a claw pin! ? Since it engages with and presses the p part, the pawl pin can be pressed without being affected by the rattling between the IJI pawl and the holder, and it is possible to reliably prevent the plowing pawl from coming out, and by extension, the tilling pawl from being pulled out. Furthermore, since the engaging portion is formed between the spring plate member and the head of the claw pin, the suppression of the claw pin by the spring plate member is not easily released.
The claw pin is more securely prevented from being pulled out.
