9th feature of the present invention forms as follows in any one in the material used for agriculture feedway of the 6th ~ 8th feature of the present invention.

The anglec of rotation of described 1st one-way clutch that the past road action of described drive division produces, sets the anglec of rotation of described 2nd one-way clutch that produces than the multiple road action of described drive division is little.

(effect of effect and invention)

[IX]-1

In the state of the 1st one-way clutch and the state of the 2nd one-way clutch are for equal state as described in preceding paragraph [VI], setting the occasion of the 1st state and the 2nd state, namely between drive division and the arm of the 1st one-way clutch and the arm of the 2nd one-way clutch, be connected with the 1st state of the 1st attaching parts and the 2nd attaching parts, and in the state that the connection of the 1st attaching parts of drive division and the 1st one-way clutch is maintained, the connection of the arm of the drive division undertaken by the 2nd attaching parts and the 2nd one-way clutch is by the 2nd state removed, the rotating speed of the driving shaft under the rotating speed of the driving shaft under the 1st state and the 2nd state, the relation of 2: 1 should be in.

If, be configured to the occasion changing the rotary speed of driving shaft thus the sendout of change unloading part in the 1st state and the 2nd state, the changing range (changing range of sendout) of the rotary speed of the driving shaft under the 1st state, should be consistent with the changing range (changing range of sendout) of the rotary speed of the driving shaft under the 2nd state.

But in fact, the rotary speed of the driving shaft under the rotary speed of the driving shaft under the 1st state and the 2nd state is not in the relation of 2: 1, and is sometimes in such as 2: 1.2 such relations.

Thus, be configured to the occasion changing the rotary speed of driving shaft thus the sendout of change unloading part in the 1st state and the 2nd state, the changing range (changing range of sendout) of the rotary speed of the driving shaft under the 1st state, and the changing range (changing range of sendout) of the rotary speed of driving shaft under the 2nd state produces deviation sometimes.

The reason shown in [IX]-2,3 that this is thought as follows.

[IX]-2

In the 2nd state, when drive division carries out toward road action, the past road action of drive division is delivered to the 1st one-way clutch by the 1st attaching parts, and driving axial prescribed direction is by the 1st one-way clutch rotary actuation.On the other hand, the past road action of drive division is not delivered to the 2nd one-way clutch.

Thus, start to carry out toward road action and the moving range end reached toward road action and the occasion that stops at drive division, there is such function: the 1st one-way clutch be connected by the 1st attaching parts with drive division is stopped relatively simultaneously, 1st one-way clutch allows the leading rotation of driving shaft, be considered to thus, (the overrun phenomenon (Japanese: drive Move Shaft オ ー バ ー ラ Application Now and resemble) hereinafter, referred to as driving shaft) is stopped after stoppingly rotating slightly to prescribed direction because of inertia when driving shaft is different.

Therefore, such as, as shown in figure 22, in the 2nd state, the anglec of rotation AA1 of the driving shaft that the past road action of drive division produces, is not the anglec of rotation A3 of the 1st one-way clutch that the past road action of drive division produces, and is considered to the anglec of rotation AA1 slightly larger than anglec of rotation A3.

[IX]-3

Relative to the 2nd state in the 1st state, when drive division carries out toward road action, the past road action of drive division is delivered to the 1st one-way clutch by the 1st attaching parts, and driving axial prescribed direction is by the 1st one-way clutch rotary actuation.Meanwhile, the past road action of drive division is delivered to the 2nd one-way clutch by the 2nd attaching parts, and the 2nd one-way clutch is driven in rotation to the direction contrary with prescribed direction, and the 2nd one-way clutch relative drive shaft dallies.

In this occasion, although the 2nd one-way clutch is driven in rotation to the direction contrary with prescribed direction, but owing to becoming the resistance to driving shaft, the overrun phenomenon of the driving shaft that the 1st one-way clutch being therefore considered to as described in preceding paragraph [IX]-2 produces is difficult to occur.

The occasion that drive division carries out the action of multiple road is also identical, and the multiple road action of drive division is delivered to the 2nd one-way clutch by the 2nd attaching parts, and driving axial prescribed direction is by the 2nd one-way clutch rotary actuation.Meanwhile, the multiple road action of drive division is delivered to the 1st one-way clutch by the 1st attaching parts, and the 1st one-way clutch is driven in rotation to the direction contrary with prescribed direction, but the 1st one-way clutch relative drive shaft dallies.

In this occasion, although the 1st one-way clutch is driven in rotation to the direction contrary with prescribed direction, but the resistance become driving shaft, the overrun phenomenon of the driving shaft that the 2nd one-way clutch being therefore considered to as described in preceding paragraph [IX]-2 produces is difficult to occur.

Thus, such as, as shown in figure 22, be considered in the 1st state, the anglec of rotation AA1 of the driving shaft that the past road action of drive division produces is the anglec of rotation A3 of the 1st one-way clutch that the past road action of drive division produces, and the anglec of rotation AA2 of the driving shaft that the multiple road action of drive division produces is the anglec of rotation A4 of the 2nd one-way clutch that the multiple road action of drive division produces.

As mentioned above, the overrun phenomenon (with reference to preceding paragraph [IX]-2) of the driving shaft brought by the 1st one-way clutch is produced in the 2nd state, the overrun phenomenon of the driving shaft brought by the 1st one-way clutch and the 2nd one-way clutch can not be produced in the 1st state, thus, the rotary speed of the driving shaft under the rotary speed of the driving shaft under the 1st state and the 2nd state does not become the relation of 2: 1, and be considered to such as to become 2: 1.2 such relations and (be considered to be configured to change the rotary speed of driving shaft in the 1st state and the 2nd state thus changing the occasion of the sendout of unloading part, the changing range (changing range of sendout) of the rotary speed of the driving shaft under the 1st state, deviation is produced) with the changing range (changing range of sendout) of the rotary speed of the driving shaft under the 2nd state.

Such as, as shown in figure 22, be considered in the 1st state, the anglec of rotation A3 " if 5 " of the 1st one-way clutch that the past road action of drive division produces, the anglec of rotation AA1 of driving shaft that then the past road action of drive division produces also is " 5 ", the anglec of rotation A4 " if 5 " of the 2nd one-way clutch that the multiple road action of drive division produces, then the anglec of rotation AA2 of driving shaft that the multiple road action of drive division produces also is " 5 ".Thus, the adding up to " 10 " of anglec of rotation AA1 and anglec of rotation AA2.

On the other hand, such as, as shown in figure 22, be considered in the 2nd state, the anglec of rotation A3 " if 5 " of the 1st one-way clutch that the past road action of drive division produces, then the anglec of rotation AA1 of driving shaft that the past road action of drive division produces is " 6 " because of the overrun phenomenon of driving shaft.

Thus, the rotary speed (anglec of rotation AA1+ anglec of rotation AA2=10) of the driving shaft under the 1st state, and the rotary speed (anglec of rotation AA1=6) of driving shaft under the 2nd state is not the relation of 2: 1.

[IX]-4

For the state described in preceding paragraph [IX]-1,2,3, in the 9th feature of the present invention, the anglec of rotation of the 1st one-way clutch that the past road action of drive division produces, sets the anglec of rotation of the 2nd one-way clutch that produces than the multiple road action of drive division is little.

Such as, as shown in figure 23, the anglec of rotation A3 of the 1st one-way clutch past road action of drive division produced is set to " 4 ", and the anglec of rotation A4 of the 2nd one-way clutch multiple road action of drive division produced is set to " 6 ".

Such as, as shown in figure 23, be considered in the 1st state, the anglec of rotation A3 " if 4 " of the 1st one-way clutch that the past road action of drive division produces, the anglec of rotation AA1 of driving shaft that then the past road action of drive division produces also is " 4 ", the anglec of rotation A4 " if 6 " of the 2nd one-way clutch that the multiple road action of drive division produces, then the anglec of rotation AA2 of driving shaft that the multiple road action of drive division produces also is " 6 ".Thus, the adding up to " 10 " of anglec of rotation AA1 and anglec of rotation AA2.

On the other hand, such as, as shown in figure 23, be considered in the 2nd state, the anglec of rotation A3 " if 4 " of the 1st one-way clutch that the past road action of drive division produces, then the anglec of rotation AA1 of driving shaft that the past road action of drive division produces is " 5 " because of the overrun phenomenon of driving shaft.

Thereby, it is possible to the rotary speed (anglec of rotation AA1=5) of the driving shaft under the rotary speed (anglec of rotation AA1+ anglec of rotation AA2=10) of the driving shaft under the 1st state and the 2nd state to be made the relation of 2: 1.

If, be configured to the occasion changing the rotary speed of driving shaft thus the sendout of change unloading part in the 1st state and the 2nd state, the changing range (changing range of sendout) of the rotary speed of the driving shaft under the 1st state can be made, consistent with the changing range (changing range of sendout) of the rotary speed of the driving shaft under the 2nd state.

(effect of effect and invention)

[X]-1

Such as, the terminal toward road action is arrived at drive division, then the occasion of carrying out rightabout multiple road action is started, driving axial prescribed direction is by the state of the 1st one-way clutch rotary actuation, terminate when drive division arrives the terminal toward road action, when then drive division starts to carry out multiple road action, be switched to driving axial prescribed direction by the state of the 2nd one-way clutch rotary actuation.When drive division starts to carry out multiple road action, the 1st one-way clutch is driven in rotation to the direction contrary with prescribed direction, and the 1st one-way clutch dallies relative to driving shaft.

In aforesaid state, when drive division starts to carry out multiple road action, if driving axial prescribed direction is slow in slightly the mechanical little play etc. of the 2nd one-way clutch inherence by the state of the 2nd one-way clutch rotary actuation, then be driven in rotation to the direction contrary with prescribed direction by the 1st one-way clutch, thus driving shaft follows the 1st one-way clutch to circle round together sometimes, the direction that driving axial is contrary with prescribed direction is thus driven in rotation slightly.

Aforesaid state, even if the terminal arriving multiple road action at drive division then starts to carry out the rightabout occasion toward road action to be also identical, in this occasion, sometimes driving shaft follows the 2nd one-way clutch to circle round together, and the direction that driving axial is contrary with prescribed direction is thus driven in rotation slightly.
