[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention arranges a driver's seat on the side of a vertical conveyor for conveying grain culms cut by a reaper to a starting end of a feed chain of a threshing device, and swings various operating levers. A first operation panel provided with a plurality of lever guide portions that are operably inserted into each is provided from the lateral outer side of the vertical transport device side of the driving seat to the front side of the lateral outer side thereof, and dust from the vertical transport device is A dust-proof wall for preventing scattering to the driver's seat side is provided upright 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. The present invention relates to a combine control unit structure provided with an operation panel.

[0002]

2. Description of the Related Art Conventionally, in the control section structure of the combine, the first operation panel is provided from the lateral outer side of the longitudinal transport device side of the driver seat to the front side of the lateral lateral outer side thereof, and also on the driver seat side of the vertical transport device. A second dustproof wall is disposed laterally outside and is formed between the first operation panel and the dustproof wall as a separate body from the dustproof wall.
There was an operation panel. Then, in such a state that the first operation panel and the second operation panel occupy most of the space between the driver's seat and the vertical conveyance device, the dust-proof wall is formed narrowly. .

[0003]

According to the above conventional technique, 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 the dustproof wall.

[0005]

The constitution, operation and effect of the invention according to claim 1 are as follows. [Structure] Feed the grain culm cut by the reaping device to the threshing device.
Operates on the side of the vertical conveyor that conveys to the beginning of the chain
Seats are arranged and various operation levers can be rocked freely
A first operation panel having a plurality of lever guide parts to be inserted therethrough
From the lateral outside of the driver's seat on the vertical conveyor side.
Installed over the outside front side , dust from the vertical transport device
A dustproof wall that prevents dust from scattering to the driver's seat side,
Standing from the end of the first operation panel on the side of the vertical conveyance device,
In the control structure of a certain combine, the dustproof wall,
Formed in a hollow chevron shape when viewed in the front-back direction with a width in the lateral direction
The ridge of the hollow mountain shape at the center of the hem in the widthwise direction.
Together is positioned in the vertical conveying apparatus nearer, said Hekomashi the side of the driver seat side of the peak portion of the dust-proof walls laterally over a predetermined range, the upwardly facing surface portion of the recessed portion for various operating switches It is configured on the second operation panel.

[Operation] Since the side surface on the driver's seat side of the dustproof wall is laterally recessed over a predetermined range, and the upward facing surface portion of the recessed portion is configured as the second operation panel. As shown in FIG. 1, the first operation panel 15 is arranged laterally outside the driver's seat 14 on the side of the vertical transport device 7, and the first operation panel 1 is provided.
By occupying the space between the vertical transfer device 5 and the vertical transport device 7 and arranging the dustproof wall 8 in the space, the lateral width of the dustproof wall 8 on the base end side is set to be the lateral width of the second operation panel as compared with the conventional one. Can only be wider. Further, each wall portion of the recessed portion which is formed by laterally recessing the side surface of the dustproof wall on the side of the driver's seat becomes a rib of the dustproof wall.

[Effect] Therefore, according to the structure of claim 1, the lateral width of the dustproof wall 8 on the base end side can be made wider than the conventional one by the lateral width of the second operation panel, and the dustproof wall has ribs. Can be formed,
The strength of the dustproof wall could be increased.

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

[Operation] In addition to the same operation as the operation according to the structure of claim 1, the following operation can be performed.
By integrally molding the dustproof wall and the first operation panel, these two parts can be integrated. Further, in the structure in which the dustproof 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 the connecting portion between the dustproof wall and the first operation panel. By integrally molding the dustproof wall and the first operation panel, such a problem can be avoided.

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

This combine has a cutting pretreatment unit 1 at the front of the machine body, a control unit 2 on the right side thereof, and a threshing device 3 at the rear. The reaping pretreatment unit 1 gradually raises the posture of the raising device 4 that raises the lodging grain culm, the reaping device 5 that cuts the stock, and the grain culm in the mown vertical posture to the sideways posture. The rearward threshing device 3 is provided with a vertical conveying device 7 that conveys it to the starting end of the feed chain 6, and is configured to be movable up and down around a horizontal axis P on the rear side.

The vertical transfer device 7 can be vertically swung about the horizontal axis P, and the vertical U-shaped support rod 19 of the vertical transfer device 7 has an inverted U-shaped support rod 19 for detecting the presence of grain stems. Side first sensor S1 and stock source side second sensor S2 are provided, and the vertical conveyor device 7 is operated to move up and down so that the tip of the conveyor grain stem is located between the sensors S1 and S2. Depth adjustment control means (not shown) is provided.

The control section 2 has a control post 12 having a steering operation lever 11 and the like standing on the front end of a machine body frame 10, a drive section 13 disposed behind the control post 12, and a driver seat above the drive section 13. 14 is provided.
