Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harvesting machine, and more particularly, to a harvesting machine including a threshing unit and a grain tank, and the grain tank is laterally opened and rotatably supported.

[0002]

2. Description of the Related Art This type of harvester, such as a combine, has a grain tank for storing grains adjacent to the threshing unit at the rear of the driver's seat. A fried cylinder for loading the grains from the threshing section into the grain tank is provided between the two. Further, a discharge auger for discharging the grains stored in the grain tank to the outside is provided.

By the way, conventionally, a power storage device (battery) for supplying power source power to each control unit of the combine having the above-described structure has been provided in an exposed state at a lower portion behind the threshing unit.

[0004]

However, according to the above-mentioned conventional battery mounting position, since the battery is mounted so as to be exposed to the outside, dust or dirt may be attached to the surroundings to be contaminated. Due to this pollution, there are problems such as self-discharge of the battery and shortening of the life.

In this case, generally, in the combine, the center of gravity of the machine body tends to be biased forward due to the engine mounting position, the mounting position of the mowing section, etc. Therefore, considering the weight balance of the machine body, for example, the combiner is located in front of the driver seat. Placing a battery is not preferred. It is also necessary to consider the viewpoint of effective utilization of so-called dead space.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a combine in which a battery is mounted at a position where the front-rear balance of the machine body can be improved and the dead space can be effectively utilized. To provide.

Further, the space (30) is provided below the inclined wall surface (34) formed so that the grains in the grain tank (20) smoothly flow downward by the action of gravity. The so-called dead space can be effectively used.

The above-mentioned reference numerals in parentheses are shown for reference to the drawings and do not limit the structure of the present invention.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an external perspective view of a main part of a combine as a harvester according to the present invention, and FIGS. 2 to 4 are views showing the structure thereof.

In the above, the combine 10 is the body 12
And a pair of left and right crawler running portions 16 and 16 for supporting the body 12 and having a driver's seat 14 above the body 1
Up and down a mowing section (not shown) for mowing the grain culm in front of 2, a threshing section 18 for threshing and selecting the grain culm cut by this mowing section, and a grain threshed by the threshing section 18. And a discharge auger 22 for discharging the grain from the grain tank 20.

The discharge auger 22 has a vertical spiral cylinder 22a at its mounting base, and the vertical spiral cylinder 22a is fixed to the grain tank 20.
Is supported so that it can be opened laterally in the directions A and B in FIG. 1 with the vertical spiral cylinder 22a as the center of rotation.

That is, the vertical spiral cylinder 22a is supported by the support member 39 standing upright from the machine body 12 via the support frame 38 and the bracket 37, and
The upper end of the vertical spiral cylinder 22a is rotatably supported by a rotary receiver 36 fixed to the grain tank 20, and the lower end of the vertical spiral cylinder 22a is rotatable via the support frame 38. Supported by. Further, the vertical spiral cylinder 22
"a" is connected to a vertical spiral drive case 40 extending from the grain tank 20 at its lower portion, and is rotatably fitted and inserted through a connecting plate 42 provided at the connecting portion. Therefore, when the grain tank 20 is laterally opened and rotated, the grain tank 20 is rotated about the vertical spiral tube 22a.

On the other hand, on the back side of the grain tank 20,
An auxiliary fuel tank 24 is attached integrally with the grain tank 20. In the figure, reference numeral 26 is the body 12
The fuel tank is provided above, and reference numeral 28 is a second spiral which returns the unsorted grains to the swing sorting unit for resorting.

Here, in the present invention, the threshing section 18 and the grain tank 20 are arranged adjacent to each other on the left and right sides of the machine body 12, and on the machine body 12 below the grain tank 20 and adjacent to the threshing section 18. It is characterized in that a predetermined space is defined in and a battery is arranged in the space.

That is, the threshing section 18 and the grain tank 2
0 is arranged behind the driver's seat 14 on the left and right sides of the fuselage 12, and below the grain tank 20 and on the fuselage 12 on the side adjacent to the threshing unit 18, a predetermined space 30 is provided. Well defined. A battery 32 is arranged between the grain tank 20 and the second spiral 28 in this space 30.

As shown in FIG. 4, in the grain tank 20, the wall surface 34 on the side adjacent to the threshing portion 18 is inclined from the middle portion in the height direction toward the inside of the grain tank bottom portion. Has been formed. The reason why the slanted wall surface 34 is formed in the grain tank 20 in this manner is that the grain stored inside is easily moved downward by the action of gravity.
The space 30 is defined between the upper surface 4 and the upper surface of the body 12.

Therefore, the battery 32 is arranged in the space 30 between the grain tank 20 and the second spiral 28, so that the so-called dead space can be effectively used without increasing the size of the present combine machine. Was available.

Next, the operation of the present embodiment will be described.

The grain culm cut by the reaping device is threshed by the threshing unit 18, and then fed and conveyed to the grain tank 20 by a fried cylinder (not shown). The grain tank 2
The grain stored in 0 is guided to the vertical spiral cylinder 22a of the discharge auger 22 by a horizontal feed spiral (not shown), and is carried out from the vertical spiral cylinder 22a to the outside.

When performing maintenance and inspection of the grain tank 20, the threshing unit 18, etc., the grain tank 20 is rotated about the vertical spiral tube 22a fixed so that the vertical position does not shift. Rotate sideways. Due to this lateral opening rotation, the space 30 below the grain tank 20 and on the side adjacent to the threshing unit 18 is largely opened, and maintenance of the battery 32, the auxiliary fuel tank 24, and the like arranged in the space 30 is easy. Becomes Moreover, since the space 30 is a dead space which is normally covered by the threshing unit 18 and the grain tank 20, the dead space can be effectively used and the batteries 32 and the like can be accumulated with dust. It is possible to store it in a clean state.

Further, since the battery 32 is disposed near the center position of the rear portion of the machine body 12, there is also an advantage that the front-rear weight balance can be improved in the combine in which the center of gravity of the machine body 12 tends to be biased forward.

[0026]

As described above, according to the present invention, the threshing section and the grain tank are arranged adjacent to each other on the right and left sides of the machine body, and on the machine body below the grain tank and on the side adjacent to the threshing section. By arranging the battery in the formed space, it is possible to improve the front-rear weight balance of the machine body, and the battery is housed inside the grain tank that is laterally opened and rotated. Can perform maintenance.

Further, since the space is defined on the side adjacent to the threshing section and the grain tank and below the tank wall inclined inward from the intermediate height position of the grain tank to the bottom, a so-called dead space is formed. Since the space is covered with the wall surface, the battery arranged therein is not contaminated by dust or the like.
