Are known. It is desirable to bend the upper end side of such a dustproof cover forward so that wind and dust are not blown directly from the dustproof cover to the driver side.

[0003]

By the way, at the time of mowing and threshing work by the combine, the driver's seat adjusts the traveling posture of the machine body by operating the multi-steering lever or the like while watching the weeding state by the divider provided in the mowing section. However, if the dust cover is bent forward, the driver sees the divider through the curved part of the dust cover, so the front view is distorted and unclear, and for long hours of work, There is a problem that eyes are easily tired and work safety is affected. The present invention was created in order to solve the above problems, even if the dust cover provided on the front side of the driver's seat is bent forward, the driver sitting in the driver's seat, The purpose of the present invention is to provide a combine dustproof cover that allows the divider to be clearly seen in a wide field of view through the dustproof cover and does not tire the eyes even during long hours of work, thus ensuring work safety. It was done.

[0004]

In order to solve the above-mentioned problems, the technical means taken by the present invention is to provide a mowing section equipped with a divider in the front part of a traveling machine body, and to arrange a driver's seat behind the mowing section. In the disposed combine, a dustproof cover made of a transparent body is provided on the front side of the driver's seat, and a left and right bent portion is provided on the dustproof cover so that the upper side of the dustproof cover is tilted forward and the dustproof cover is provided. The bent portion of the cover is provided at a position deviated from the line-of-sight direction when the driver in the driver's seat sees through the dust-proof cover and looks at the tip of the divider. In a combine having a mowing section provided with a driver's seat behind the mowing section, a dustproof cover made of a transparent body is provided in front of the driver's seat, and a left and right bent portion is provided on the dustproof cover. , The upper side of the dust cover In addition to tilting toward the other side, the bending part of the dust cover is bent at an angle where the line of sight is substantially orthogonal to the dust cover when the driver in the driver's seat sees through the dust cover and looks at the tip of the divider. Further, in a combine with a cutting section provided with a divider at the front of the traveling machine body and a driver's seat disposed behind the cutting section, a dustproof body made of a transparent body is provided in front of the driver's seat. A cover is provided, and the dustproof cover is provided with a bent portion in the left-right direction so that the upper side of the dustproof cover is tilted forward and the bent portion of the dustproof cover is penetrated by the driver in the driver's seat. When the tip of the divider is viewed, it is characterized in that it is provided at a position that passes through substantially the center in the vertical direction on the upper side of the dustproof cover in which the line of sight is tilted.

[0005]

Therefore, according to the present invention, the dust cover provided on the front side of the driver's seat has its upper part tilted forward due to the bent portion in the left-right direction, so that the wind hitting the dust cover is guided upward. As much as possible, the amount of direct spraying to the driver's seat is reduced. When the driver in the driver's seat looks through the dust-proof cover and looks at the tip of the divider, the bent portion of the dust-proof cover is located out of the line-of-sight direction, so there is no distortion in the front field of view and the divider is clearly visible. You can see the tip of. In addition, the line-of-sight when looking at the tip of the divider is substantially orthogonal to the dust-proof cover, which improves the transparency and makes the front field of view more clear, and the upper part of the dust-proof cover with the line-of-sight tilted forward. Since it passes through the substantially central position above and below, the front view is widened and the tip of the divider can be easily seen.

The driver's seat panel 13 is provided with a multi-steering lever 14 for turning on / off the side clutch and moving the cutting unit 6 up and down. It is provided so that it can be operated front and back and left and right. Reference numeral 15 denotes a side panel provided on the side of the thresher 10 of the driver's seat 8, and a gear shift lever, a sub gear shift lever and the like are provided inside the side panel 15. Reference numeral 16 is an engine cover.

The driver's seat 8 has a thresher 1 from the front thereof.
A front dust-proof cover 17 and a lateral dust-proof cover 18 are continuously provided on the side surface on the 0 side. The front dust-proof cover 17 is formed of a plate-shaped transparent body, and its lower end is fixedly attached to the front panel 19 on the front side of the driver's seat panel 13 in an overlapping manner. It protrudes slightly inclined forward.
Then, a bent portion A in the left-right direction is formed substantially at the center of the protruding front side dust-proof cover 17, and the upper side 20 thereof is inclined forward, whereby the cross-sectional shape of the front side dust-proof cover 17 is inclined forward. It has a cross shape. Further, the height h from the ground to the upper surface of the front dust-proof cover 17 is
It is arranged to be higher than the height h1 to the bottom of the driver's seat 8.

On the other hand, the lateral dustproof cover 18 has its front end portion connected to the side end of the front dustproof cover 17 and its lower end side fixed to the side panel 15, and a side surface reaching from the front of the driver's seat 8 to the threshing machine 10. The front dust-proof cover 17 and the side dust-proof cover 18 are integrated over the entire length. Reference numeral 21 denotes a threshing cover that covers the grain culm supply port provided at the tip of the threshing machine 10.

During the mowing and threshing work, the driver sitting on the driver's seat 8 operates the multi-steering cover 14 in order to maintain an appropriate running posture while seeing the divider 7 through the front dust-proof cover 17. However, as shown in FIG. 5, the bent portion A provided on the front dust-proof cover 17 is located downwardly with respect to the driver's line-of-sight direction B looking at the tip of the divider 7. Further, the bent portion A is bent and formed so that an angle θ formed by the upper side 20 of the front dust-proof cover 17 and the line-of-sight direction B is approximately 90 °, and further from the line-of-sight direction B to the lower end of the upper side 20. The distance F and the distance F ′ to the upper end are configured to be substantially equal to each other, and the tip of the divider 7 can be seen through the upper and lower substantially central positions of the upper side 20 tilted forward. Has been done.

Further, the position of the bent portion A is set lower than the grip portion 14a of the multi-steering lever 14, and the grip portion 14a of the front dust-proof cover 17 is shown in cross section.
By forming a dogleg shape in the direction away from the grip 14, the gap between the dustproof cover 17 and the grip 14a is widened, and the front side dustproof cover 17 is operably operated by the multi-steering lever 14.
I'm trying not to touch. The lower side 22 of the dustproof cover 17 and the multi-steering lever 14 are substantially parallel to each other and do not interfere with each other when the multi-steering lever 14 is fully operated forward.

Furthermore, the front dustproof cover 17 has
A brim portion 23 is formed between the front panel 19 and the front panel 19 to prevent dust and the like from entering. That is, the front panel 1
The front dustproof cover 17 attached and fixed to the front panel 9 is integrally formed with a brim portion 23 that faces the upper end surface of the front panel 19, and the joining line between the front panel 19 and the front dustproof cover 17 is made to coincide with each other. 19 and front dust cover 1
The dust and the like are prevented from entering between them. Further, the brim portion 23 is provided with a constant inclination angle so that dust that is trying to accumulate on the upper surface of the brim portion 23 slides down, and the upper surface angle α and the lower surface angle β of the brim portion 23 with respect to the horizontal line O are substantially equal to each other. By making them the same, the workability and strength of the front dustproof cover 17 are improved. The side dustproof cover 18 is also provided with the same brim portion 24 as described above facing the upper surface of the side panel 15.

In the above-described structure, when performing the mowing and threshing work, the wind blows from the front as the machine runs, but the driver's seat 8 is formed in a dogleg shape from the front to the side. Front dust cover 17 and side dust cover 1
8 is integrally provided, the wind flow W can be directed upward and sideward, and the upper end of the front dust-proof cover 17 is higher than the seat surface of the driver's seat 8. It is possible to reduce as much as possible to directly blow on the driver's seat 8. And the driver sitting in the driver's seat 8
When the front end of the divider 7 is seen through the front dustproof cover 17, the bent portion A of the front dustproof cover 17 is located away from the line-of-sight direction B, and therefore no distortion occurs in the front view. Moreover, since the line-of-sight direction B is substantially orthogonal to the upper side 20 of the front dust-proof cover 17, the transparency is improved and the field of view becomes clearer. In addition, since the front side is seen through the substantially central position of the upper side 20 tilted forward, the front view is widened and the tip of the divider 7 can be easily seen.

Further, even if the multi-steering lever 14 is operated while looking at the divider 7, the front dustproof cover 17 has a dogleg shape in the direction away from the grip portion 14a. It can be operated smoothly without hitting. On the other hand, since the brim portion 23 is integrally formed on the front dustproof cover 17, dust and the like do not enter between the front dustproof cover 17 and the front dustproof cover 17, and the bent portion A is formed on the front dustproof cover 17. I mean
The entire front dust cover 17 can be reinforced.

In summary, the present invention is a combine harvester in which a reaper having a divider is provided in the front of a traveling machine body, and a driver's seat is arranged behind the reaper, and a transparent body is provided in front of the driver's seat. The dust cover is made of, and the left and right bent portions are provided on the dust cover so that the upper side of the dust cover is tilted forward and the bent portion of the dust cover is covered by the driver in the driver's seat. When looking at the tip of the divider through the, it is provided at a position deviated from the direction of the line of sight, and a cutting unit equipped with a divider is provided at the front of the traveling machine body,
In a combine in which a driver's seat is arranged behind the reaping part, a dustproof cover made of a transparent body is provided on the front side of the driver's seat, and a left and right bent portion is provided on the dustproof cover so that the upper side of the dustproof cover is forward. And the bent portion of the dust cover is bent and formed so that the line-of-sight direction is substantially orthogonal to the dust cover when the driver in the driver's seat sees through the dust cover and looks at the tip of the divider. Furthermore, in a combine having a mowing section provided with a divider at the front of the traveling machine body and a driver's seat disposed behind the mowing section, a dustproof cover made of a transparent body is provided at the front side of the driver's seat, The dust cover is provided with a bent portion in the left-right direction, and the upper side of the dust cover is tilted forward, and the bent portion of the dust cover is pushed by the driver in the driver's seat through the dust cover to attach the tip of the divider. When I saw Since it was installed at a position that passes through the center of the top and bottom of the upper part of the dust cover with its line of sight tilted, even if wind hits the dust cover installed on the front side of the driver's seat during reaping work, it tilts forward from the bent part. Since the upper side of the dustproof cover guides the wind upwards, it is possible to minimize the wind blown directly to the driver's seat along with the dust.
Moreover, the dustproof cover can be reinforced by the bent portion. When the driver in the driver's seat sees through the dust cover and looks at the tip of the divider, it can be seen clearly without causing distortion in the field of view, because the bend of the dust cover is outside the driver's line of sight. You can In addition, if the bending part is formed so that the line of sight when the tip of the divider is viewed is substantially orthogonal to the dustproof cover, the transparency of the dustproof cover will be good, and the front view will be clearer With the one that passes through the substantially vertical center on the upper side of the dustproof cover in which the direction is tilted, the front field of view becomes wide, so the tip of the divider can be easily seen. Therefore, even when working for a long time, the eyes are not tired and the work can be performed safely.
