[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dustproof cover for combine harvesters.

[0002]

2. Description of the Related Art Conventionally, in a grain culm passing portion to a threshing portion on a rear end portion of a pretreatment unit of a combine, an actual Kaihei 2-57 is used.
No. 323, Japanese Utility Model Publication No. 59-3699, the grain culm delivery part is provided above the grain culm delivery part for dust prevention to the driver's seat, and on the side of the driver's seat and in front of the threshing part. It is known that a dustproof cover for covering is attached to the fuselage side, and a dustproof sheet for vertically separating the threshing portion and the side operation panel is provided on the side of the dustproof cover.

[0003]

However, the conventional dustproof cover on the upper part of the threshing section and the dustproof sheet for vertically partitioning the threshing section and the side operation panel have only the dustproof effect on the side of the driver's seat, and the There was no effect to prevent dust from entering from the left front side. For this reason, it is not sufficient to prevent dust from entering the driver's seat.

[0004]

A dustproof structure for a driver's seat in a combine of the present invention for solving the above problems is provided with a driver's seat 6 in front of the machine body 1 and a pretreatment section on the side of the driver's seat 6. 9, a front operation panel 14 is provided in front of the driver's seat 6 on the fuselage 1, and a side operation panel 16 is provided on the side of the pretreatment section 9. A first feature is that a dust-proof cover 18 made of a transparent member that covers the side of the panel 16 on the side of the pretreatment unit 9 and has an upper end protruding upward from the upper surfaces of both panels 14 and 16 is formed in a substantially L shape in a plan view. I am trying.

A second feature is that the upper peripheral surface of the dust cover 18 is curved or bent forward or laterally with respect to the lower peripheral surface of the dust cover 18 so as to project in an eaves-like shape. This is the point where the facing concave surface is formed.

Further, the upper peripheral edge of the dust-proof cover 18 is projected forward and laterally in the outer peripheral direction to form an upper-edge shielding portion, and at least the shielding portion in the field of view through which the front end portion of the pretreatment portion 9 is seen from the driver's seat 6 is seen. The third feature is that a part of the plate is formed in a flat plate shape.

[0007]

As described above, since the dust cover 18 surrounds the periphery of the driver's seat 6 excluding the right side face, the dust generated by the operation of the pretreatment unit 9 is raised by the dust cover 18 while rising. Since a large amount of dust is prevented from entering the driver's seat 6 by being blocked, the working environment of the driver's seat 6 can be maintained in a good condition. Further, since the upper portion of the dust-proof cover 18 projects outward in the outer peripheral direction so as to form a recess in the upper outer peripheral surface, the air flow rising from the pretreatment unit 9 is smoothly guided to the side of the driver's seat 6 and escaped rearward. , The dustproof effect is further improved. Furthermore, since the dust-proof cover 18 is a transparent member and a flat plate-like portion is provided at a part of its upper edge,
Not only is the visual check of the pretreatment section 9 and the operating section and the working section in the vicinity thereof not hindered, but also the distortion during the see-through due to the bending of the transparent cover member is eliminated, and the visual check of the working section and the operating section can be performed accurately. .

Similar to Nos. 2 and 33, it has a flat plate shape.

Further, the mounting portion 39 is provided on the upper rear end of the mounting portion 39.
A mounting rib 47 having a substantially triangular shape in a plan view is provided substantially at a right angle to the mounting rib 47, and a mounting hole 48 is provided in the mounting rib 47. The side cover 21 having the above-described configuration is gently curved inward toward the inside as a whole, and has a curved shape of the side-side panel case 49 that covers the side operation panel 16 and the body-side panel 17 in a plan view. It fits. In addition, each flat portion 33, 43, the cover portion 3
4, 38 and the mounting portions 36, 39 are respectively continuous.

The side cover 21 having the above-mentioned structure includes the cover portion 3
The mounting portion 39 is arranged along the panel case 49 in a direction in which the portion 8 projects outward from the side surface of the panel case 49, and is fixed to the panel case 49 by a bolt or the like using a mounting hole 41. At this time, since the mounting hole 41 has the elongated hole shape as described above, the mounting position can be finely adjusted. In addition to this, the front portion 31 and the front cover 19 are connected so that the connection hole 37 of the front portion 31 matches the connection hole 28 of the front cover 19.

Further, the mounting ribs 47 are fixed to the body side panel 17 with bolts or the like using the mounting holes 48, so that a mounting structure is formed so that dust or the like is unlikely to enter between the panel portion and the side cover 21. .

The side cover 21 is attached as described above, but at this time, the rear end of the upper surface cover portion 42 has a cutout portion 44.
This prevents the dust cover 12 from hitting the right front end. Further, dustproof sheets 50 and 51 made of transparent vinyl or the like are fixed to the side of the dustproof cover 12 on the driver's seat 6 side and to the notch 43 at the rear end of the cover portion 38,
It enables auxiliary operations by hand when there is a trouble in cutting and transporting. In other words, the left front side of the driver's seat 6 and the side thereof are surrounded by the side cover 21, the dustproof cover 12, and the dustproof sheets 50 and 51.

The side cover 2 attached as described above
1 shows that the cover portion 38 juts out to the side of the panel case 49 slightly obliquely above, and an upper surface cover portion 42 is projected above the panel case 49 substantially parallel to the ground, and in addition, it is oblique from the end of the upper surface cover portion 42. The flat portion 43 is provided on the upper side, and the upper side of the inheriting and conveying portion 11 and the side of the panel case 49 are covered like eaves. The upper end of the flat portion 43 projects upward from the side operation panel 16 and the machine body side panel 17, and almost hides the side operation portion.

The dustproof action of the dustproof cover 18 constructed as described above will be described below. The grain culm which is caused to be harvested by the pretreatment unit 9 and cut and then lifted and conveyed is inherited to the threshing unit 4 by the feed chain at the grain culm inheriting and conveying portion 11. Sometimes dust is generated and rises upward and rearward. First, the dust scattered near the entrance of the threshing unit 4 is not scattered upward because the dust cover 12 is provided as described above.

On the other hand, the dust rises from the front side to the side of the driver's seat 6, but first, the dust in front of the driver's seat 6 may enter the inside of the driver's seat 6 by the cover portion 27 and the flat portion 22 of the front cover 19. Can not. That is, the cover portion 27 and the flat portion 22 function as a dust blocking portion in the front portion of the driver's seat. Further, the dust rising toward the side operation panel 16 (toward the driver's seat) cannot enter the driver's seat due to the cover portion 38, the upper surface cover portion 42, and the flat portion 43 of the side cover 21, and the above-mentioned 3 parts 38, 42 and 43 function as a dust blocking portion on the side of the driver's seat 6. The dust cover 50, 51 prevents dust from entering the driver's seat near the joint between the side cover 21 and the dust cover 12. The flat portion 33, the cover portion 34, and the mounting portion 36 of the front portion 31 of the side cover 21 also function in the same manner as the above-described shielding portion substantially in front of the side operation panel 16.

Further, since the dust of the grain culm is generated during the forward movement of the combine, X, toward both sides of the machine body 1 along the inward concave surface of the dust cover 18 and the left peripheral surface, Guide the gas flow in the Y direction. Therefore, dust is discharged in the Y direction in front of the driver's seat 6 and in X direction in the driver's seat 6 side.

Further, at this time, the operator 52 needs to look at the front end of the pretreatment section 9 and the like in order to perform the cutting operation by the combine accurately. Therefore, the eye line 53 of the worker 52 is configured to reach the front end of the pretreatment unit through the flat portions 22, 33, 43.
Since 2, 33, and 43 are flat plates as described above, the front can be seen without distortion.

[0022]

According to the present invention configured as described above, since the dust generated by the operation of the pretreatment section is blocked by the dustproof cover while rising, a large amount of dust is prevented from entering the driver's seat. Therefore, the working environment of the driver's seat is kept good, and the dustproof cover is a transparent member, so that the visual effects of the pretreatment section, the working section and its surroundings and the working section are not obstructed.

Further, in the case where the upper part of the dust-proof cover projects in the outer peripheral direction so as to form a recess on the upper outer peripheral surface, the air flow rising from the pretreatment section is smoothly guided to the side of the driver's seat and rearward. Since it escapes, the dustproof effect is further improved.

Further, by providing a transparent flat plate-like portion of the pretreatment portion of the shielding portion on the upper edge of the dust-proof cover, the distortion of the transparent cover member due to the bending at the time of see-through is eliminated, and the working portion and the operating portion can be accurately viewed. Confirmation becomes possible.
