Description

[Detailed description of the invention] (a) Industrial field of application The present invention provides support for tilling claws without the need for fastening U such as bolts and oaks. Concerning means.

(b) Technical Background and Problems Generally, a support means for removably supporting a JJI plow on a plow holder installed on a tillage shaft is known, but in the conventional support means, Since the holder hole of the claw holder, in which the holder part of the tiller claw can be freely fitted, was formed in a simple box shape, the holder part of the tiller claw could be inserted into the bolt hole of the claw holder. When fixing it, fasteners such as nuts and bolts are required for pole 1. Therefore, it becomes complicated to attach and remove the above-mentioned lll claws, and if the fasteners become loose, it becomes difficult to tighten the tiller claws (in J mode). There is wobbling,
As a result, the above 11j m nail becomes JFA (H,
Alternatively, there was a problem of bending and sipping.

Furthermore, conventional supporting means improved from this are shown in FIGS. 6 and 7. 1) A large number of claw holders 103 (only one is shown in the drawing and the others are omitted) are attached to the outer circumferential surface of the tiller shaft 101, which is connected to the gear A7 case (none of which is shown). In the setting (b), insert the held part 111 connected to the blade part 109 of the tilling claw 107 into the pin hole 113 in the hole 105 of the claw holder 103.
When the retaining pin 115 is removably supported through the IIrI hole, the inner surface of the holder hole 105 is plowed both above and below with the pin hole 117 as a border.
/The left and right sides gradually decrease in the J direction.11 Wedge-shaped 1
This holder hole 10 is also formed on the middle slopes 105a and 105b.
! The holder portion 111 of the tilling claw 107 to be inserted into the holding part 111 of the tilling claw 107 was also formed with similar wedge-shaped inclined surfaces 111a, 1111] on both the upper and lower sides so as to correspond to the above. Therefore, even if the above-mentioned connection port 1- or put-p is not used, if the tilling claw 107 receives the reaction force of soil tillage during use of the M-till device, the damage to the plowing claw 107 in 1. The boulder part 111 has a small production of "1 bottle 11F) and the front part a
And the sloped surfaces 111a and 111b of the rear part 1) are connected to this and the sloped surface 10ba of the holder hole 105 on the side I.
, I C) 51+ has a configuration in which the so-called wedge is wedged in Δ, 1).

However, in such a conventional tilling claw support 111 means, the inner surface of the holder hole 105 of the claw holder 103 is formed into a wedge-shaped inclined surface 105a, 'lO51+.
4Il claw 107 that fits 1Φ into this holder hole 105
The machining to form the part 111 of the boulder into the tree-shaped inclined surfaces 111a and 111b corresponding to "1" is extremely difficult and tends to cause machining errors. -105 and the holder 111 may be stuck in the fitted state, and in this case, there is a problem that the tilling claws 167 are not supported reliably.

(c) Purpose of the invention This invention has been made in view of the problems of the conventional technology.
The purpose of (a) is to provide a tiller that can be easily supported without the need for tightening bolts, nuts, etc., and that can be supported reliably and firmly. The object of the present invention is to provide a means of supporting the nail.

(d) Structure of the Invention In order to achieve the above-mentioned object, the present invention involves fitting the held part 7 of the tilling claw 5 into the claw holder 3 protruding from the tilling shaft 1, and attaching the held part 7 of the tilling claw 5 to the claw holder 3. Part 7 @dislocated
1. When the tilling shaft '1 is rotated, the fitting hole 9 where the claw holder 3 and the held part 7 are fitted, and the 1 & fitting side that fits into this fitting hole 9 are Structure of the support means for the tilling claw in which the fixing member 11 is extended by IIQ by twisting the claw holder 3 of the section 7.

(e) Examples Examples of the present invention will be described below with reference to Drawing 1. -titzu r5T
Explain in detail.

Figure 1 is based on this invention) Jll Kozumeia: 91, +

First, to explain the configuration, the outer circumferential surface of the tilling shaft 1 has a plurality of CI) IIX no.
When viewed from the side, the vines 3 have a sword-like shape 4), and are fixed by means such as welding at appropriate intervals f.

The claw holder 3 is formed in the form of a box by five integral elements 14. The holder hole 9 of this claw l truder 3 is formed into a dogleg-shaped parallel inclined surface 15. The fixed part 111)<) is formed.

In addition, the i
t. Small claw 5.1, bolted part 7 and blade part 19 (in the drawing)
is composed of partially omitted λ.

In the held portion 7, intermediate bodies on the left and right sides are formed into parallel surfaces, and the left and right inclined surfaces 13.1 of the claw holder 3 are parallel to each other.
5 and is configured so that a gap C is created.

Then, the held portion 7 of the claw 5 is moved to the claw holder 3.
The hole 13 of the claw holder 3 and the bottle hole 2 of the part 7 of the tilling claw 5 are inserted into and engaged with each other in the hole 9.
1 and the pruning bottle 23, thereby fixing the tilling claws 5 to the claw holder 3 on the right side. In addition, stop pin 2
3 is handled with a split bottle (not shown) or the like.

Next, to explain the operation using the above structure, when the tilling shaft 1 is rotated by the drive of the tilling device and the tilling claws 5 start tilling the soil, the tilling claws 5 move the blade portions 19 together. Due to the reaction force of soil tillage, the held part 7
is attached to the claw holder 3 and around the conversion bottle 21.
(The lower part of the held part 7 is shown in Fig. 3.)
, J,) on the parallel inclined surface 1 of the rear side a of the claw-shaped Le Sea 3
5.17-J 4-J is pressed, and conversely, the F part of the held part 7 is pressed against the parallel inclined surface 15°17 of the front side of the claw holder 3 as shown in FIG. It will be forced upon you. (The holder part 7 is firmly and reliably fixed by the fixing part 11 formed on the dogleg-shaped parallel inclined surfaces 15 and 17 by twisting.

Note that this invention is limited to the above-mentioned embodiment.

For example, the nail holder 3 side or both the nail holder 3 and the held portion 7 can be fixed by twisting (1).

(F) Effects of the Invention - As is clear from the above explanation, according to the configuration of the present invention, the tilling claws can be easily supported without using fasteners such as bolts, hooks, etc., and the tilling shaft can be easily supported. When the boulder is rotated, the fixing portion is fixed by torsion due to the rotation of a portion of the boulder relative to the pawl 11-, so that the effect of firmly and reliably fixing is improved.
