Description

[Detailed description of the invention] [Industrial application field] The invention is used in rice transplanters and other general machinery, and is used in rice transplanters and other general machines.
The present invention relates to an operating device capable of operating two operating parts.

[Prior Art] In rice transplanters and other general machinery, many operating parts must be operated almost simultaneously, but in rice transplanters in particular, when the machine rotates, the first thing to do is to operate the planting clutch operation lever. A series of operations such as squeezing the planting part to disengage the planting clutch, then operating the planting part control lever to raise the planting part, and at the end of the rotation, lowering the planting part and then engaging the planting clutch. This is done step by step using two operating levers.

[Problems to be solved by the invention] However, in such operations, the planting portion is raised before the planting clutch is completely cut, or the planting clutch is raised before the planting portion is completely lowered. Not only is there a risk of erroneous operation such as turning the planting clutch on or off, but there is also the drawback that the operation lever must be changed when switching the planting clutch and when raising and lowering the planting section, making the operation complicated.

[Means for Solving the Problems] The present invention was developed based on the above circumstances, and it is possible to operate two independently operated operating parts through predetermined steps by operating one operating lever. The object of the present invention is to provide an operating device that does not require changing the lever for each actuating part, and does not cause errors in the order of actuation.

For this purpose, the present invention has an operating lever 3 inserted and guided through a single slit-shaped guide 2 to interlock and switch between a hydraulic device for raising and lowering the planting section and a planting clutch in a planting transmission mechanism. In the middle of the movement path of the operating lever 3 in the slit-shaped guide 2, the operating lever 3 is at a position where its direction of movement changes, and when the planting clutch is "disengaged", the planting section is "downward". A boundary position P ₂ is provided, and from this boundary position P ₂ , on one side, there is a planting clutch ``on'' operating area with the planting part in the ``down'' state, and on the other side, the planting clutch is ``off''.
In this state, a planting part "raise" operation area is provided, and due to the forward movement operation of the operating lever 3 within the slit-shaped guide 2 without turning the operating lever 3, the planting part is "raised" and the planting part is moved from the clutch "off" position. When the attachment part "descends", the clutch passes through the "off" position, and when the planting part "descends", the clutch reaches the "on" position, and conversely, due to the double action operation, the clutch "enters" when the planting part "descends". The present invention is characterized in that the clutch is operable to be switched from the "down" position to the clutch "off" position when the planting section is "down", and then to the clutch "off" position when the planting section is "up".

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

In FIG. 1, a slit-shaped guide 2 is formed on the operation panel 1a and is bent at right angles from an intermediate position.
An operating lever 3 extending from the inside to the outside is movable. Inside the operation box 1, two shafts 4 and 5 are horizontally mounted so as to cross each other at right angles, and one shaft 4 has a cylindrical ring member 6 as shown in FIG.
is externally fitted so as to be able to rotate on the shaft 4, and this ring member 6 is formed with two ears 6a, 6a, and between these ears 6a, 6a, the attached end of the operating lever 3 is attached to a pin 7.
It is pivoted by. Therefore, the operating lever 3 can be rotated over the entire area of the slit-shaped guide 2.

Further, another ring member 8 is fitted onto the shaft 4 at a position corresponding to the slit-shaped guide 2 so as to be rotatable on the shaft 4 (see Fig. 3), and a support rod is mounted on this ring member 8. A U-shaped driven member 10 as shown in FIG. 4 is fixed to the upper end of this support rod, and one end of an arc-shaped connecting member 11 is pivotally supported at an intermediate position of the support rod 9. A wire 12 connected to a hydraulic device for moving the planting section up and down is attached to the other end of the connecting member 11, and the wire 12 extends through the bottom side 1b of the operation box, and the movement of the driven member 10 is , support rod 9, connection member 11 and wire 12
The information is transmitted to the planting area by a transmission mechanism consisting of:

On the other hand, at a position corresponding to the slit-shaped guide 2 on the shaft 5 perpendicular to the shaft 4, a ring member 13 is rotatably fitted, and a support rod 14 similar to that shown in FIG. and a transmission mechanism for switching the planting clutch consisting of a wire,
A driven member 15 having the same shape as the driven member 10 is fixed to the upper end of the support rod 14, with the open portion of the driven member 15 being at a different position.

Three switching positions are set for the slit-shaped guide 2, and these switching positions are near both ends of the slit-shaped guide 2 and an intermediate (boundary) position of the slit-shaped guide 2, that is, a position where the moving direction of the operating lever 3 changes. It is set in the bent part. In the operation panel 1a of FIG. 1, from the folded part in the figure,
The slit part extending downward is the planting part operation area R ₁
The slit portion extending from the bent portion to the right in the figure is the planting clutch operation area _R2 , and the driven member 10 reciprocates only in the planting part operation area _R1 according to the movement of the operating lever 3. The driven member 15 is adapted to reciprocate only in the planting clutch operating region _R2 in accordance with the movement of the operating lever. When the operating lever 3 is present at the bent portion, both driven members 10 and 15 overlap vertically,
At this time, the driven member 10 that reciprocates in the planting part operation area R ₁ is open with respect to the planting clutch operation direction, and the driven member 15 that reciprocates in the planting clutch operation area R ₂ is opened in the planting clutch operation area R 2 . The _intermediate bending portion, that is, the position where the moving direction of the operating lever 3 changes, also serves as a switching position between both operating regions.

Next, the operation of the above embodiment will be explained.

Now, on the operation panel 1a in Fig. 1, move the lower end of the slit-shaped guide 2 to the planting section "up" switching position.
P ₁ , the bent part, that is, the position where the moving direction of the operating lever 3 changes, is the planting part "down" switching position P ₂ and the planting clutch "off" position P ₂ , and the right end thereof is the planting clutch "on" position P Suppose you set it to ₃ .

While planting seedlings, the planting section is lowered,
Since the planting clutch is engaged, the operating lever 3 is located at the "on" position _P3 . When you have finished planting the seedlings and are about to start rotating, first move the operating lever 3 from the "ON" position _P3 to the "OFF" position P2 _.
(“lower” position P ₂ ). Then, driven member 1
5 is also moved to the "off" position, which loosens the planting clutch wire and releases the clutch. Note that at this time, the driven member 10 is in the "lowered" position, so the planting section remains lowered.

Next, when the operating lever 3 is changed from the "down" position _P2 to the "up" position _P1 by changing its direction of movement, the driven member 10 moves to the "up" position, and the driven member 1
5 is left in the "off" position _P2 . Driven member 10
Due to this movement, the wire connected to the hydraulic system is pulled, and the planting section rises while the drive is stopped.
Rotate in this state, and when the rotation is finished, tilt the operating lever 3 in the opposite direction to the "on" position.
If it reaches P ₃ , the driving will start after the planting part has descended.

In this way, when there are two actuating parts to be operated and they are to be operated in stages, by configuring the operating device as described above, it is possible to operate the two actuating parts with only one operating lever. Since it can be operated,
There is no need to provide a control lever for each operating part,
There is no need to worry about having to hold a different control lever each time you operate it. Moreover, in the case of rice transplanters,
There is no possibility of erroneous operation such as raising the planting part before the planting clutch is not completely closed or putting the planting clutch in before the planting part is completely lowered.

In the above embodiment, the guide is bent into an L-shape, and the bent portion is set as an intermediate position, and the operating lever 3 moves in a different direction, releasing the interlocking relationship from the driven member that is one of the actuating parts. However, the intermediate (boundary)
It goes without saying that it does not necessarily have to be a bent part, nor does it need to be an L-shaped guide, as long as the operating lever can release the interlocking relationship with each actuating part depending on the position.

[Effects of the invention] As detailed above, according to the invention, the operating parts of the two independently operated hydraulic devices for lifting and lowering the planting section and the planting clutch are operated by a common operating lever. A boundary position is provided in the middle of the operation path at the position where the direction of movement of the operating lever changes, and the operation that passes through this boundary position allows the two operating parts to be reliably switched, making it easy to change the position of the operating lever, etc. This eliminates the hassle, and since there is a position to change the direction of the operating lever at a predetermined position (boundary position) in the operating path, the operation of the planting clutch and the operation of raising and lowering the planting section can be differentiated here. This becomes clear and has the practical effect of completely avoiding the occurrence of erroneous operations.
