DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation panel provided with a plurality of lever guide portions through which various operation levers are swingably operably inserted. The present invention relates to a control section structure of a combine provided over an outer front side.

[0002]

2. Description of the Related Art Conventionally, in the above-described control section structure of a combine, the operation panel has been formed so that the entire operation panel has a substantially horizontal posture.

[0003]

In the control section structure of a combine, generally, a first operation panel portion located outside the driver's seat and a second operation panel portion located forward of the first operation panel portion are provided respectively. A lever guide portion is formed, and the operation lever inserted through the latter lever guide portion located diagonally forward of the driver is in an upright position as shown in FIG. 5 (the position of the operation lever 21 shown by a solid line). And the position where it fell forward (the position of the operation lever 21 shown by the two-dot chain line)
And swing over it. The swing range of the operating lever is set in this manner, for example, rather than swinging the operating lever between a position where it falls forward and a position where it falls backward with the upright position as an intermediate point, This is because operability is known to be easy to operate.

According to the prior art, the operation panel is formed such that the second operation panel portion is also substantially in a horizontal position similarly to the first operation panel portion. The length of the lever protruding from the panel is different from the state in which the operating lever is located at the rear swing stroke end (corresponding to the state in which the operating lever is upright) and the front swing stroke end (where the operating lever is at the frontmost position). (Corresponding to a fall-down state), the driver was more likely to have an uncomfortable feeling when operating the lever.

[0005] In addition, the driver sometimes observes the condition of the sensor for adjusting the handling depth of the vertical transport device located diagonally forward and below the driver's seat and the condition of the grain stalk raising device. Since the operation panel is formed in a state in which the entire operation panel is in a substantially horizontal posture, the front end side of the operation panel becomes obstructive and it is difficult to observe the situation in a normal driving posture while sitting on a driving seat, While sitting, the upper body had to be obliquely tilted to the front and stood up.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to prevent a driver from feeling uncomfortable when operating a lever, and to provide a vertical transport positioned diagonally forward and downward of a driver's seat. The point is to enable the driver to easily observe the situation of the sensor for adjusting the handling depth of the device, the grain stalk raising device, and the like while the driver is in the sitting posture.

[0007]

The constitution, operation and effect of the invention according to claim 1 are as follows.

[0008] [Construction] In the control unit structure of the combine described at the beginning, the operation panel has a first operation panel portion located on the lateral outside of the driver's seat in a substantially horizontal posture, and The second operation panel on the front side is formed in a state in which the front operation is inclined downward.

[Operation] [A] The operation panel is located on the first lateral side of the driver's seat.
Since the second operation panel portion on the front side of the operation panel portion is formed so as to be inclined forward and downward, the operation lever inserted into the lever guide portion of the second operation panel portion located diagonally forward of the driver is used. However, even if the swinging operation is performed between an upright position (the position of the operation lever 21 shown by a solid line in FIG. 5) and a position inclined forward (the position of the operation lever 21 shown by a two-dot chain line in FIG. 5) ( The reason for setting the swing range of the operation lever in this way is that
This is because the lever is easily operated as described above), and the length of the lever protruding from the second operation panel portion is determined by the swing stroke end of the rear side of the operation lever (the position where the operation lever stands upright). 5), and a state where it is located at the front swing stroke end (corresponding to a position where the operation lever is tilted forward most) as shown in FIG.

[B] By setting the second operation panel portion to the forward-downward inclined position, a sensor for adjusting the handling depth of the vertical conveying device, ie, a sensor for adjusting the handling depth of the vertical conveying device, and the grain puller are provided. The field of view toward the raising device expands downward.

[Effect] Therefore, according to the above operation [A],
The driver can be prevented from feeling uncomfortable at the time of operating the lever, and the operation [b] allows a sensor for adjusting the handling depth of the vertical transport device located diagonally in front of the driver's seat and the lower side, and a grain stalk pull. It has become possible for the driver to easily observe the state of the raising device and the like while sitting in a sitting posture.

The construction, operation and effect of the invention according to claim 2 are as follows.

[Structure] In the invention according to claim 1,
A main transmission operation lever for traveling is inserted through a lever guide portion of the second operation panel portion, and a threshing clutch operation lever and a reaping clutch operation lever are inserted through the lever guide portion of the first operation panel portion.

[Operation] In addition to the same operation as the operation according to the first aspect, the following operation can be obtained. The main shift operation lever is normally operated to switch over three or more operation positions (for example, high speed, medium speed, low speed position), and it is easier to operate when the distance between adjacent operation positions on the hand side is wider. Therefore, the length of the operation lever is set to be long to widen the interval between the adjacent operation positions. If such a long operation lever is provided on the first operation panel portion side on the lateral outside side of the driver's seat, there is a disadvantage that it is difficult to operate the lever. Is arranged on the side of the second operation panel portion, so that the above-described inconveniences are not caused and the lever can be easily operated.

The length of the main transmission operation lever projecting from the second operation panel portion is such that the main transmission operation lever is located at the rear swing stroke end (corresponding to the position where the operation lever is upright). And the state at the front swing stroke end (corresponding to the position where the operation lever is tilted forward most) as shown in FIG.

The threshing clutch operating lever and the reaping clutch operating lever are switched over two operating positions (clutch-engaging position and disengaging position). Since the interval between them can be widened, even if such a shortened operation lever is provided on the first operation panel portion on the lateral outer side of the driver's seat, the lever can be easily operated.

In general, the operation lever inserted through the lever guide portion of the first operation panel located on the lateral outside of the driver's seat falls forward and backward with the upright position as an intermediate point. In the configuration of the second aspect, the threshing clutch operation lever and the reaping clutch operation lever are inserted through the lever guide portion of the first operation panel portion in a substantially horizontal posture. The length of the operation lever protruding from the first operation panel portion is determined between the state where the operation lever is located at the rear swing stroke end (corresponding to the position where the operation lever is tilted most rearward) and the front side. At the end of the swing stroke (corresponding to the position where the operation lever is tilted forward most).

[Effect] Accordingly, the driver can be prevented from feeling uncomfortable when operating the main shift operation lever, the threshing clutch operation lever, and the reaping clutch operation lever, and the same operation as the above operation [2]. The driver can easily observe the conditions such as the sensor for adjusting the handling depth of the vertical transport device located diagonally under the driver's seat and the lower part of the driver's seat and the cereal stem raising device while the driver is in the sitting posture Now you can.
