DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arrangement in which a driver's seat is arranged on the side of a vertical conveying device for conveying grain stalks cut by a mowing device to the starting end of a feed chain of a threshing device, and swings various operation levers. A first operation panel having a plurality of lever guide portions that are operably inserted separately from each other is provided from a lateral outer side of the driver's seat on the vertical transport device side to a lateral outer front side thereof, and dust from the vertical transport device is removed. A dustproof wall for preventing scattering to the driver's seat side is provided three-dimensionally from the end of the first operation panel on the side of the vertical conveyance device with a width in the horizontal direction, and a second wall for various operation switches is provided. The present invention relates to a control unit structure of a combine provided with an operation panel.

[0002]

2. Description of the Related Art Conventionally, in the above-described combine control section structure, a first operation panel is provided from a lateral outer side of a driver's seat on a side of a vertical transport device to a front side of a lateral outer side of the driver's seat. A dustproof wall is disposed on the lateral outside, and a second dustproof wall formed separately from the dustproof wall is provided between the first operation panel and the dustproof wall.
An operation panel was arranged. In this state, since the first operation panel and the second operation panel occupy most of the space between the driver's seat and the vertical transport device, the dustproof wall is formed to be narrow. .

[0003]

According to the above prior art, since the dustproof wall is formed narrow, the strength of the dustproof wall is not strong, and there is room for improvement.

An object of the present invention is to increase the strength of a dust-proof wall.

[0005]

The constitution, operation and effect of the invention according to claim 1 are as follows. [Configuration] In the control section structure of the combine described at the beginning, a side surface of the dustproof wall on the driver's seat side is laterally recessed over a predetermined range, and an upwardly facing surface portion of the concave portion is configured in the second operation panel. It is.

[Operation] The side surface of the dust-proof wall on the driver's seat side is laterally recessed over a predetermined range, and the upwardly facing surface portion of the recess is formed in the second operation panel. As shown in FIG. 5, the first operation panel 15 is arranged outside the driver seat 14 on the side of the vertical transport device 7 side, and the space between the first operation panel 15 and the vertical transport device 7 is fully used. By arranging the dust-proof wall 8 in the space, the lateral width of the dust-proof wall 8 on the base end side can be made wider than that of the related art by the width of the second operation panel. In addition, each wall of the recessed portion in which the side surface of the dustproof wall on the driver's seat side is laterally recessed over a predetermined range serves as a rib of the dustproof wall.

According to the first aspect of the present invention, the width of the dust-proof wall 8 on the base end side can be made wider than that of the related art by the width of the second operation panel. Can be formed, so that the strength of the dustproof wall can be increased.

The construction, operation and effect of the invention according to claim 2 are as follows. [Configuration] In the invention according to claim 1, the dustproof wall is formed integrally with the first operation panel.

[Operation] In addition to the same operation as the operation according to the first aspect, the following operation can be obtained. By forming the dustproof wall and the first operation panel integrally, the two parts can be integrated into one. Further, in the structure in which the dust-proof wall and the first operation panel are formed separately, there is a problem that dust from the vertical transport device enters the driver's seat side from a connection portion between the dust-proof wall and the first operation panel. By forming the dustproof wall and the first operation panel integrally, such a problem can be avoided.

[Effect] In addition to the same effect as the effect of the first aspect, the structure can be simplified, and the dustproof effect can be enhanced.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show the front part of the combine according to the present invention. This combine has a cutting pre-processing unit 1 at the front of the fuselage, a control unit 2 on the right side, and a threshing device 3 at the rear. The pre-cutting processing unit 1 is a raising device 4 for raising the lodging grain culm, a cutting device 5 for cutting the root of the stock, and gradually changing the posture of the cut vertical grain culm to the horizontal falling position. And a vertical conveying device 7 that conveys the feed chain 6 of the rear threshing device 3 to the start end thereof, and is configured to be able to swing up and down around the horizontal axis P on the rear side.

The vertical transport device 7 can freely move up and down around the horizontal axis P, and the inverted U-shaped support rod 19 in the vertical posture of the vertical transport device 7 has a head for detecting the presence or absence of a grain culm. A first sensor S1 on the side and a second sensor S2 on the stock side are provided, and the vertical conveying device 7 is moved up and down so that the spike of the conveyed culm is positioned between the two sensors S1 and S2. Depth adjustment control means (not shown) is provided.

As shown in FIGS. 2, 3, and 4, a dust-proof wall 8 for preventing dust from the vertical transport device 7 from scattering toward the driver's seat 14 is provided with a width in the horizontal direction and three-dimensionally. The first operation panel 15 is erected from the end on the side of the vertical transport device 7,
More specifically, the dustproof wall 8 has a hollow chevron shape when viewed in the front-rear direction.
The upper end thereof is inclined downward and the outer end of the front portion is inclined toward the driver's seat 14 closer to the front side.
Resin molding is performed separately from the operation panel 15, and a lower end thereof is pinned to a downward lower end of the first operation panel 15 (not shown).
A long through-hole 9 is formed in the upper part on the rear end side of the dustproof wall 8 before and after the dust-proof wall 8 penetrates in the lateral direction.
The handle 18 is formed around the handle.

Further, as shown in FIG. 5, the side surface of the dust-proof wall 8 on the driver seat 14 side is laterally recessed over a predetermined range, and the upward surface of the recess H is connected to various operation switches 24A and 24B. , 24C, 24D (handling depth adjustment switch, horizontal slide switch of the pre-cutting unit, etc.).

As described above, the dustproof wall 8 is formed such that the upper end thereof is inclined forward and downward, and the outer end of the front portion is inclined so that the front end is closer to the driver seat 14 side.
The driver's view in the diagonally forward side (front end side of the dust-proof wall 8) in the state of sitting on the driver's seat 14 expands downward, and the driver can maintain the vertical transport device 7 in the normal driving posture sitting on the driver's seat 14.
