Description of the Related Art Conventionally, a cultivating body having a plurality of wheels and cultivator blades according to various working conditions is provided on a cultivating shaft protruding from both left and right sides of a power transmission case of a cultivating machine (including a rotary type). It is equipped with attachments for running or plowing work. The cultivating shaft is formed in a polygonal shape such as a hexagonal shape or a square shape in a cross section orthogonal to the axial direction, and a polygonal shaft inserting hole into which the cultivating shaft is inserted is provided on the attachment side. The shaft insertion hole has a size such that the cultivating shaft hardly looses.

浮き上がらせる。A worker alone performs the work of exchanging such attachments for traveling or tilling work or vice versa on cultivated land such as fields. Explaining the replacement procedure, for example, in the case of exchanging from a wheel to a cultivator work body, the worker manually supports the tilter from one of the left and right sides of the cultivator to the other side, and supports the left and right sides of the power transmission case. Use the wheel as a fulcrum and let the other wheel float above the ground.

Next, the worker holds the tilling work body in hand, sets the rotary shaft having the shaft inserting hole of the tilling work body in the same direction as the tilling shaft, and inserts the tilling shaft into the shaft inserting hole. And the axis of rotation is
A retaining pin for connection is inserted and fixed together with the tilling shaft inserted in the shaft insertion hole. The above work is shown in FIG.

負担がかかる。In the above-mentioned work, the worker always holds the cultivator with one hand so that one wheel of the cultivator or the cultivating work body is lifted from the ground. , One hand is closed. Therefore, attachments such as wheels and tillers must be replaced with only one hand. During this work, the ground is generally unstable. Further, the tilling work body is heavy and too burdensome for the worker. Further, even if the cultivator is tilted forward with one hand and both the left and right wheels or the cultivating work body are raised and replaced, a great burden is similarly imposed on the worker.

容易に行い得るものではない。[0006] Further, since the shaft inserting work of the cultivating shaft and the rotating shaft of the attachment is polygonal such as hexagonal and square, the cross-sections are made to prevent rattling.
Since there is very little play during insertion, the tiller shaft cannot be inserted into the shaft insertion hole unless the corners match perfectly. further,
Since it is necessary to consider the position of the retaining pin, replacement work of the attachment becomes even more difficult and troublesome.
Physical fatigue and mental fatigue overlap, and it is not something that can be done easily by one worker.

(See FIG. 12). At this time, by aligning the opening portion of the rotary shaft 10 with the six taper portions of the cultivating shaft A, the rotary shaft 10 can be easily rotated in the circumferential direction, and the rotary shaft 10 can be further rotated.
The work of pushing from the side to the polygonal shaft portion 4 side becomes easy.

することができる等の種々の効果を奏する。According to the first aspect of the invention, the power transmission case 3 of the cultivator is projected from the power transmission case 3, the tip side thereof is the insertion portion 5 having a substantially circular cross section, and the base portion side continuous with the insertion portion 5 is the polygonal shaft portion 4. By using the tiller shaft in the tiller formed as above, firstly, the attachment B on the tiller shaft A can be exchanged extremely efficiently, and secondly, the above work can be performed efficiently. Even though it is possible, various effects such as a simple structure can be achieved without complicating the structure of the tilling shaft A.

４に回転軸１０を挿入させることができる。To explain the above effect in detail, the tip side of the cultivating shaft A is formed as an inserting portion 5 having a substantially circular cross section, and the base side of the cultivating shaft A is formed as a polygonal shaft portion 4 continuously from the inserting portion 5. Therefore, when the attachment B having the rotary shaft 10 whose inner peripheral side surface is similar to the polygonal shaft portion 4 is attached to the cultivating shaft A, the cultivating shaft A
From the insertion portion 5 at the tip of the rotary shaft 10 of the attachment B
Will be inserted into. Therefore, since the insertion portion 5 has a circular cross-section, it can be easily inserted into the rotary shaft 10, and the attachment B can be temporarily mounted in the insertion portion 5 and only slightly rotated in the axial direction. Since the positions of the corners of No. 4 and the corners of the inner peripheral side surface of the rotary shaft 10 of the attachment B are the same, the polygonal shaft portion can be simply pressed by pressing the attachment B so that the fixing holes are aligned with each other. The rotary shaft 10 can be inserted into the shaft 4.

ある。This operation is extremely simple and quick. That is, in the conventional type, since the entire cross section has a polygonal shape in the axial direction, the rotary shaft 10 of the attachment B must be aligned with the polygonal axis from the beginning of the mounting operation. While searching for a place where the corners match each other, the hand of the worker holding the attachment B is physically tired by the weight of the attachment B and is physically given to the worker.
Mental fatigue increases. On the other hand, in the present invention,
First, by inserting the insertion portion 5 of the cultivating shaft A into the rotating shaft 10 of the attachment B, the attachment B can be brought into a substantially temporary fixing state with respect to the cultivating shaft A, and therefore the attachment B is not held in the hand. In addition, the hand for exchanging the attachment B has a much higher degree of freedom than that of the conventional type, and can perform good work without causing physical fatigue or burden on the worker.

As a result, the work of inserting the rotary shaft 10 of the attachment B into the insertion portion 5 of the cultivating shaft A can be further improved. That is, the insertion portion 5 is equivalent to the imaginary inscribed circle of the polygonal shaft portion 4 and can be accommodated in the inner peripheral portion of the rotary shaft 10 relatively easily. Therefore, the insertion portion 5 is inserted into the rotary shaft 10 of the attachment B. The part 5 can be easily inserted, and the work can be made even more efficient.
