Abstract

PROBLEM TO BE SOLVED: To guide grain culms in a pressed state with the side wall of a seat- supporting stand so as not to damage them and to make the side wall lightweight and small in a combine harvester. SOLUTION: A seat-supporting stand 12 is equipped with a side wall 12c covering the external side of a chassis in a driver's seat 11. An external side face 18 of the side wall 12c is equipped with a slant, external side face 18b which has a vertex T situated at a preset level of height from the ground between the front end A and the rear one B of the face 18 and between the bottom end C and the top one D of the face 18. As going from the vertex T to every circumferential edge of the face 18, the face 18 is formed to be recessed toward the inside of the chassis in proportion to the distance from the vertex T.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating portion structure of a combine having a driver seat for supporting a driver's seat, the driver's seat being provided with a lateral side wall covering the lateral side of the fuselage.

[0002]

2. Description of the Related Art Conventionally, in the above-mentioned combine, a downwardly inclined surface is provided on a lateral outer side surface of a lateral side wall portion of a seat support so as to be retracted inward toward the lower end side of the lateral outer surface. The inclined outer surface portion is provided, and when performing a middle splitting operation or the like, the planted grain culm located on the lateral outside of the operating portion is guided laterally outward or downward by the inclination of the inclined outer surface portion, and is guided after the operating portion. Some were able to work while making it difficult for the cereal stems to enter the inside of the fuselage on the side.

[0003]

Heretofore, the inclined outer surface portion has been a flat inclined surface over the entire length from the front end to the rear end of the lateral outer surface of the lateral side wall portion. For this reason, a relatively sharp corner was formed on the front end side of the lateral side wall, and the grain had been easily damaged by the corner. It is an object of the present invention to provide a driving unit structure of a combine that can press and guide the cereal stem by the side wall portion of the seat support so as not to be easily damaged, and can reduce the side wall portion.

[0004]

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

[0005] [Construction] In a driving unit structure of a combine, in which a seat supporting table for supporting a driver's seat is provided with a lateral wall portion that covers the driver's seat laterally outside the fuselage, Sloped between the front end and the rear end of the lateral outer surface of the horizontal outer surface so that a vertex exists at the level of the set height from the ground surface between the lower end and the upper end of the lateral outer surface,
In addition, even when going from the apex to any part of the entire peripheral edge of the lateral outer surface, the inclined outer surface that is inclined so as to retreat toward the inside of the aircraft as the distance from the apex increases, the outer lateral surface of the lateral side wall is It is on the side.

[Operation] The level at which the tip of the planted grain culm is located or a level close thereto is set as the set height.
Then, the tip side of the planted grain culm located on the side of the driving section,
The lower end portion of the inclined outer side surface portion located below the apex portion or the vicinity of the apex portion is hit from the front end side thereof.
Then, in the lower side surface portion, due to the inclined shape of the inclined outer side surface portion, as it moves away from the apex portion to the front of the fuselage or as it moves downward to the fuselage side, Since the stalks are retracted inside the fuselage, the planted cereal stalks are guided laterally outward and downward.
Thus, while avoiding the formation of a sharp corner on the front end side of the lateral side wall as in the related art, the lateral side wall presses and guides the planted grain culm located on the lateral side of the operation unit in a laterally outward or downward direction. As described above, the side wall portion is made to act on the planted grain culm.

In addition, since the inclined outer surface has a shape in which a vertex exists between the front end and the rear end of the lateral outer surface and between the upper end and the lower end, the vertex is located at the upper end of the lateral outer surface. Compared to forming on existing ones, the thickness of the upper side of the side wall portion can be suppressed to a small value for the size of the inclination angle of the lower side portion that presses the grain culm, and the side wall The portion can exhibit excellent strength by the shape of the inclined outer surface portion. In addition, compared to the apex formed at the rear end of the lateral outer surface, the magnitude of the inclination angle of the lower side portion that presses on the grain culm is determined by the rear end side of the side wall portion. In addition, the thickness of the side wall portion can be suppressed to a small value, and the lateral side wall portion can exhibit excellent strength by the shape of the inclined outer side surface portion.

[Effect] Therefore, when performing a middle splitting operation or the like, the grain culm is made to be in a state where it is hard to be damaged even when the grain culm hits the front end side of the lateral side wall, and the grain culm is machined by the inclined outer side surface portion having an appropriate inclination angle. It is possible to harvest while reducing the occurrence of grain damage by working while effectively pressing outward and downward so that it is difficult to enter the inside.

In addition, the side wall portion can be made compact by minimizing the thickness of the upper end side and the rear end side as much as possible, and at the same time, exhibiting excellent strength and having high durability. Can be

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

[Structure] In the structure of the invention according to the first aspect, a lateral side wall portion having the inclined outer side surface portion is attached so as to be freely opened and closed.

[Operation] A seat support base is provided with an opening in which a side wall portion serves as a lid. Since the side wall portion exhibits excellent strength due to the shape of the inclined outer surface portion, when the opening of the seat support is closed, the seat support is reinforced by the side wall portion and the size of the opening is divided. A desired strength can be exhibited.

[Effect] A relatively large opening is provided while preventing the seat support from lacking in strength, and the seat support can be advantageously used as an engine bonnet in a state where the driving portion can be easily inspected.

The structure, operation and effect of the invention according to claim 3 are as follows.

[Structure] In the structure of the invention according to claim 1 or 2, the engine is covered by the seat support.

[Operation] The driving part is covered by using the seat support base as the engine hood.

[Effect] The driving part can be covered at low cost by using the seat support base as the engine hood.
