Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a clutch operating device, in which a main clutch installed in a towing vehicle of a passenger or HP agricultural machine can be operated with a foot-operated pedal to turn it on or off. This invention relates to a clutch operating device to be operated.

Conventionally, riding-type rice transplanters have a direct-swinging type of pedal, and after stepping on the pedal, when the pedal is rotated further on the side of the foot, the pedal is held in the depressed state. A clutch operating device having a locking mechanism that releases the above-mentioned depressed state by interlocking a beta on the side has been known.

However, the above conventional structure has poor operability as it requires another operation to swing the bevel while the bevel is depressed, and if you are not accustomed to this operation, the locking mechanism will not engage. It had the disadvantage of being difficult to remove and sometimes causing danger, such as stepping off the bettaru.

This invention aims to eliminate the above-mentioned drawbacks and has taken the following technical measures.

In other words, the clutch θυ is "disengaged" by stepping on the foot-operated beta /l/<Ino, which is linked to the pedal.
So, when you release the pedal, there is only one clutch (1).
A moving member (a) is provided, which is linked to a proper part in the clutch actuation mechanism, and moves forward and backward when the beta alpha force is depressed and released.
), the moving part 4-A (2) is locked by one beta depression operation to maintain the depression shape (■), and the moving part 4-A (2) is unlocked by another beta depression operation. This is the configuration of the clutch operating device equipped with a locking mechanism.

With this configuration, the present invention makes it extremely easy to turn on and off the foot-operated clutch device, and even people who are not indignant can maintain the clutch in the ``off'' state by simply stepping on the foot pedal. It is safe because even if you take your foot off the pedal, it will not start moving to the side, and the next time you turn on the clutch, the pedal in the depressed state will be a little strange. The clutch can be "disengaged" simply by depressing the pedal, and the clutch "on/off" operation can be performed quickly and reliably.

One embodiment of the present invention is described above based on the drawings; (1) is a towing vehicle body;
An engine (4) covered by a bonnet (3) is mounted on the upper part of the niJ side of the aircraft frame (2) including Set up the 0 stroke, throw the control handle (6) 1, and
: Part (pair of left and right front wheels for d operation wL (7), (7
) and the rear wheel Cg) which extends rearward and downward from both left and right sides of the transmission case (2a) and is mounted on a shaft at the rear end of the chain link (8), (8), I! +1 mounted on an axis.

θD is a clutch, which loosely winds the transmission bell 1-IJ→ between the driving pulley (1) of the engine (4) and the driven pulley 03 of the transmission case (2a), and tightens and loosens the tension pulley (1υ). θQ is a tenton boolean arm.

(1 is a betal, which is attached to one end of the clutch arm 08 whose active part is rotatably pivoted to the machine frame (2) and protrudes from the floor surface (2b) of the cockpit), A bracket (11) which is integrated with this clutch arm 0 and which protrudes downward (circle) and the tension arm LJL9 are connected by a rod cAn, and a clutch (11) which is pressed into the
lJJj, and when the step is released, it becomes 1-person] IIN is completed. C D is a return spring.

(2) is a movable part, which is installed in the machine frame (2) so that it can be moved back and forth by being inserted into a support installed in the rear direction of the MiJ.

(Foundation) is a "Tori A" slot that is set up together with Mobile Department Moon (C).

(C) is a rotating rod with a single digit of the cam floor (C), which is rotatably mounted on the 1 frame (C) with a pin (A).

(to) is a cam groove, which is bored in the cam plate fixed to the machine frame (2) and has a heart shape when viewed from the side. A cam floor (C) is fitted into this groove (C).

(To) is a spring that tensions the pivot rod (C) forward.

01) Ke O1J clutch arm α clause and moving part interest (e)
This is a connecting frame that connects the two together so that the moving member (goods) moves in the 1) il direction when stepping on the betaru α force.

The front side of the heart-shaped cam groove (C) has an ε-shape as shown in FIG. 4, and the front apex of the groove (C) (
A) and the rear apex (0) are vertically shifted, and when moving the moving part (C) forward, the cam floor (C) attached to it is always forced to the rear apex (B). It is designed to be introduced in the future.

0'4 is 113 planting device, clear tank (c), seedling planting E 1
It is a well-known device consisting of a rod, a ground leveling float, etc., and is attached to the rear of the 013 towing vehicle body (1) via a link mechanism so that it can move up and down. ( B) is a preliminary seedling mounting stand.

Next, to explain the function of the upper side, when there are no seedlings in the seedling tank (to) during seedling planting work and the seedlings that have been placed in advance on the preliminary seedling mounting table (b) are supplied,
The pilot should step on the beta (17). Then, tension pulley Q41 (the bell that had been tensioned until then and was transmitting power from the engine (4) to the transmission case (2a) side as lυ rotated downward) was loosened via the rod handle, and the main clutch was released. Set αυ to 1 cut.

At the same time, the movable part (c) moves in the 1fiJ direction, and the cam floor (c) moves inside the fixed cam groove. do.

When the front end of the groove (C) is reached, the arrow (P) in Figure 4
The cam floor (E) moves backward as shown in 176
It enters the rear vertex (b) of '2B and becomes stable.

At this time, if you stop pressing the lever /l/(1), the clutch θυ is held in the "off" state.

Therefore, the operator should take his/her feet off the Betaru Q71 and freely change the direction of his/her body to load the seedlings on the preliminary seedling loading platform (B)-1 into the seedling tank (G).

Next, to resume work, it is best to depress the betal (17) again and immediately release it. At this time, the top of the groove (4) (
A) and (B) are shifted to the top 13, so this time it's the groove (C)
Move the lower side of to return to the original state. Therefore, the clutch (11) is turned on.

In addition, in the case of "2 side", the above operation will be necessary if the Betaru 0 force is depressed too much, but as shown in Fig. A switch is provided to detect movement, and this switch (
When c) turns ON, the driver's 1) 1 ■ side
It is convenient to turn on the warning lights, which have been partially replaced, to reduce erroneous operations.
