DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating lever structure for a traveling mobile agricultural machine such as a binder or a tiller.

[0002]

2. Description of the Related Art Conventionally, a binder for cutting and bundling grain stems planted in a field is provided with an engine and a rod-shaped handle having grips on the left and right sides behind an airframe having left and right running wheels. A mowing unit with a binding machine arranged to the right is installed in front of the fuselage. The left and right handles of the binder are provided with side clutch levers for gripping operation, respectively, and the reaping section is a counterclockwise reaping and binding operation because the binding machine is disposed on the right side. A traveling lever that controls the operation and a working lever that controls the operation of the reaper and the binding machine are arranged in parallel at the same length, and both levers can be operated simultaneously or independently.

In addition, a work machine clutch lever is provided on the right side of the handle and a traveling clutch lever is provided on the left side, and it is necessary to operate the left and right clutch levers while holding the handle at the start of the mowing work. There is a problem that is bad.

[0004]

The binder having the above structure is designed to operate the running wheel and the working lever simultaneously by operating the running lever and the working lever with the left hand in a driving posture in which the handle is gripped by the right hand when starting the cutting and binding work. The cutting unit and the binding machine are operated simultaneously to cut and tie the planted cereal stalks in forward travel and bind them, and release and bind the tied grain stalks to the right-hand side of the cut area opposite to the uncut area. Work can continue.

[0005] Further, when the left side clutch lever is gripped at the end of the reaping strip to turn the machine body to the left and perform the mowing, there are cases where it is desired to stop the operation of the reaping unit and the binding machine, or to stop traveling and reverse. At this time, the user operates the left working lever or the traveling lever with the right hand while holding the left side clutch lever. However, in the conventional operation lever structure of the binder, the traveling lever and the work lever are erected close to each other with the same length.
When operating suddenly, the discrimination of both levers is unclear and erroneous operation may occur, and when operating the outer traveling lever, the inner working lever must be operated in a large detour so as not to touch the inner working lever However, there is a problem that it is difficult to perform a quick operation.

An object of the present invention is to provide an operation lever structure in which the operability of the two levers of the conventional device is improved.

[0007]

In order to achieve the above object, an operation lever structure of a traveling type mobile agricultural machine according to the present invention is provided in a traveling type traveling agricultural machine having rod-shaped left and right handles 3.
The operation levers are arranged side by side on one side of the handle 3, and the height of the grip portion of the operation lever located outside the machine body is formed higher than the grip portion of the operation lever located inside by the operation space.

The operating lever located on the outside of the machine is a traveling lever 7 and the operating lever located on the inside is a working lever 8. Further, the traveling lever 7 and the working lever 8 are provided on the handle 3 of the binder A on the side of the uncut land.

[0009] Since two operation levers are provided on one side of the handle 3, and the height of the grip portion of the operation lever outside the inner operation lever is arranged at a position higher than the operation space, For example, when operating the inner operation lever, the inner operation lever can be moved until the hand is stopped by the grip portion of the outer operation lever, and the operation can be performed by grasping the inner operation lever in that state. Also, when operating the outer control lever, it is possible to put a hand on the outer control lever where the grip is protruding by moving the control lever direction while slightly raising the upper eye. The operation of the lever can be reliably performed.

[0010]

An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, A is a binder shown as an example of a traveling type mobile agricultural machine provided with an operation lever structure 1 according to the present invention. An engine 2b is provided behind a body 2 having left and right traveling wheels 2a, and a gripper is provided on left and right. A loop-shaped handle 3 is provided as an example of a rod-shaped handle, and a raising device 4a, a cutting blade 4b, and a grain culm guide plate (transverse feeding device) 4c for laterally feeding a harvested grain culm are provided in front of the machine body 2. The cutting unit 4 is provided at the right end of the cutting blade 4b and at the terminal end in the lateral direction of the grain stalk.

A cover is provided at the front end of the raising device 4a so as to be detachable, and a sensor for detecting the presence or absence of a cereal culm in the cereal culm guide passage of the raising device 4a to turn on and off the harvesting device. The server S is arranged swingably. The binder A is provided with side clutch levers 6, 6 on the left and right sides of the steering wheel 3, and operates the left and right running wheels 2a separately by operating the left and right side clutch levers 6, 6 respectively. Direction operation can be performed.

In the binder A, since the binding machine 5 is disposed on the right side of the cutting unit 4, the cutting and binding traveling work (hereinafter referred to as the cutting direction) in the field takes a counterclockwise operation. As shown in FIG. 2, a lever guide 30 provided on the left side of the handle 3 has a traveling lever (traveling clutch lever) 7 for controlling the traveling operation of the machine body and a working lever (working machine) for controlling the operation of the reaper 4 and the binding machine 5. Clutch lever)
8 is provided with an operating lever structure 1 of the present invention described later, so that the operability of both levers 7 and 8 can be improved and a smooth harvesting and binding operation can be efficiently performed. .

As shown in FIG. 2, the operating lever structure 1 has a crank type guide groove 31 in which the traveling lever 7 and the working lever 8 are formed outside the lever guide 30, and a linear type groove formed in the inside thereof. In the guide groove 32 of
Horizontal base of both bases (lever support shaft shown in FIGS. 3 and 4)
It is pivotally supported at 33 to be able to rotate back and forth.

As shown in FIG. 4, the height of the outer running lever 7 is formed higher than the upper end of the inner working lever 8 so as to protrude only by the grip portion. A space K is formed. The operation space K facilitates visual observation of the two levers 8 and 7 installed close to each other. For example, when operating the traveling lever 7 by moving the right hand from right to left, the operation space K is moved above the work lever 8. This is a space for making it easy to grasp the grip portion of the traveling lever 7 while it is usually sufficient for the length of the grip portion, thereby improving the ease of identification by tactile sensation and the operability. Have to be able to.

As shown in FIG. 4, the traveling lever 7 and the working lever 8 are arranged in a compact mounting structure with their base portions approaching each other, but are bent so that the upper portions thereof are sequentially separated from each other. The whole is formed in an X shape. Therefore, when a single operation is performed by grasping one lever, an appropriate operation is performed without being disturbed by the other lever, and both levers can be simultaneously operated with one hand.

The traveling lever 7 and the working lever 8
A transmission clutch mechanism (not shown) on the body 2 side is operated by an operation link 9 and an operation mechanism 9 such as a wire similar to those of the conventional device.
The forward and backward movement positions of the travel lever 7 allow the body 2 to move forward and backward, and the travel stop operation is performed at an intermediate neutral position.

Further, in the front and rear operation position of the working lever 8,
The working units of the reaper 4 and the binding machine 5 can be activated and stopped, respectively. When the working lever 8 is positioned at the intermediate position, the sensor bar S for detecting the presence or absence of a grain culm shown in FIG. 1 enters a sensing state, and the sensor bar S moves the grain culm in conjunction with the previous operation of the traveling lever 7. When it senses, it can be set to an automatic operation state in which the work unit is automatically operated.

When starting the cutting and binding work using the binder A provided with the operating lever structure 1 according to the present invention,
The driving lever 7 and the working lever 8 are simultaneously tilted forward with the left hand in the driving posture in which the steering wheel 3 is grasped with the right hand. Then, the left and right running wheels 2a, the cutting unit 4 and the binding machine 5 are simultaneously operated, and while traveling forward, the planted grain culm is harvested and bound, and the bound grain culm is located on the right side opposite to the uncut ground side. The cutting and bundling operation can be performed while releasing the cut and sewn material to the cut area.

When turning the body 2 to the left at the end of the straight reaping strip on the field to perform round cutting, when the left side clutch lever 6 is gripped, the right traveling wheel 2a remains in the transmission state and the left Since the running wheel 2a is in the non-transmission state, the left turning steering is performed as in the case of the conventional device, and the cutting and binding work in the lateral direction of the field is performed. In addition, the vehicle can travel and travel toward the next row.

In the case of performing the above-mentioned round mowing, if it is desired to stop the operation of the mowing part 4 and the binding machine 5 while turning and holding the left side clutch lever 6, the left hand is provided by the handle 3. By cutting (pulling) the working lever 8 disposed on the left side of the handle 3 with the right hand while performing the steering operation without releasing, the reaping and binding work is interrupted, and the running is continued. Then, after the turning of the machine is completed, the work lever 8 is quickly entered again with the right hand and operated (tilted forward).

At this time, the operating lever structure 1 according to the present invention
According to the binder A provided with, the height of the traveling lever 7 located on the outer side of the body of the two operating levers is formed to be longer than the length of the grip portion and longer than the working lever 8 located on the inner side. It is easy to visually check the two traveling levers 7 and 8 installed close to each other. In addition, even if the working levers 7 and 8 are not visually observed, the operator can perform the operation of releasing the right hand to the left side to perform any one of the working levers. Because we can grasp 7,8,
Due to the difference in height between the operation levers 7 and 8 in the operation space K, discrimination based on tactile sensation can be performed accurately, and erroneous operation can be prevented.

Further, the working lever 8 is formed to be short inside on the right hand side so that the operator can easily operate the working lever 8 by gripping it with the right hand. The operator can operate the inner working lever 8 without touching the outer running lever 7 without touching the right hand, or can lightly touch the running lever 7 to recognize the position of the working lever 8 so that trouble-free smooth harvesting can be performed. Bundling work can be performed efficiently.

The traveling lever 7 is "turned off" with the right hand.
If the operator wants to do so, as shown in FIG. 4, the inner working lever 8 is formed such that the traveling lever 7 is formed to be shorter than the “working space K” and further away from the traveling lever 7 so that the right hand can be moved from the right handle 3. Release the outer running lever 7 on the left side
Can be operated by moving the right hand with the shortest straight distance to the grip.

Therefore, like the conventional mobile agricultural machine having the traveling lever 7 and the working lever 8 having the same length, the outer traveling lever 7 is operated by bypassing the hand on the working lever 8 disposed inside. There is also an advantage that the operation of the traveling lever 7 can be promptly performed while preventing erroneous operation. In the above-described embodiment, the operation lever structure as a binder is illustrated, but the invention is not limited to this, and can be used in a plowing work machine for walking or the like.

[0025]

The operation lever structure of the traveling type mobile agricultural machine according to the present invention has the following effects by being constructed as described above. In a traveling mobile agricultural machine having left and right handlebars, two operation levers are arranged side by side on one handle, and the height of the operation lever located on the outside of the body is higher than the upper end of the operation lever located on the inside. Since it is formed, it is easy to visually check the traveling lever and the working lever that are installed in close proximity. In addition, by providing the difference between the heights of the two levers for the operation space, it is possible to recognize and grasp any of the operation levers, for example, only by laterally moving the right hand with a sideways motion, As a result, farm work can be performed efficiently while preventing erroneous operation of the two operation levers.

The operating lever located on the outside of the fuselage is a traveling lever, and the operating lever located on the inner side is a working lever. Since the lever is formed at a lower position, the lever can be easily gripped by the other hand. Furthermore, the outer traveling lever and the inner working lever can be accurately recognized and operated, so that trouble-free harvesting and binding work can be performed efficiently and smoothly, and is particularly suitable as an operating lever structure for a binder. Device can be provided.
