Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine in which a working unit and a traveling unit are movable relative to each other in the left-right direction. More specifically, the operating unit is integrated with a traveling device to maintain a good control feeling. The present invention relates to a technique for improving the left-right weight balance without changing the weight.

[0002]

2. Description of the Related Art Conventionally, a reaping unit can be laterally slid with respect to a machine body, and the reaping unit can be laterally slid so that both a state suitable for split cutting and a state suitable for rotary cutting can be obtained. There is a known structure (Japanese Patent Application Laid-Open No. 5-
153841 publication).

[0003]

In a combine harvester, a threshing section is usually located on the left side of the machine body, and a grain storage section such as a grain tank or a bagging hopper is located on the right side. Since the grains that have been threshed are stored in the grain container, the right side of the aircraft gradually becomes heavier. Therefore,
Regardless of whether the mowing unit can slide laterally or not, when the grain storage unit is full of grains, the center of gravity is closer to the right side, and in the wetland, the crawler on the right side sinks heavily. It may be difficult to turn around, or it may be difficult to run straight, which adversely affects the running performance. An object of the present invention is to improve the maneuverability of the combine by preventing the left-right balance of the machine body from changing as much as possible even when the load of the grain container changes.

[0004]

[Means for Solving the Problems]

[Structure] A first aspect of the invention is a relative movement in which a traveling unit including a crawler traveling device and a driving unit and a working unit including a threshing unit and a grain accommodating unit can be relatively moved and adjusted in the left-right direction of the machine body. A side plate on the left and right outer sides of the body of the grain accommodating unit that is provided with a mechanism is configured to be laterally outwardly displacable, and the working unit has a standard position that protrudes from the traveling unit by a predetermined amount to the left and right lateral sides, and From the standard position to the moving position where the working unit is most moved to the opposite side of the grain containing unit existing side with respect to the running unit, between the working unit and the running unit due to the relative moving mechanism. The relative position is configured to be movable, and the amount of protrusion of the grain container at the moving position from the traveling unit is set to be substantially equal to the amount of protrusion of the grain container at the standard position from the traveling unit. It is characterized by being done.

A second aspect of the invention is characterized in that, in the first aspect, the mowing section and the engine are arranged in the traveling section.

A third invention is the same as the first or second invention,
The weight balance in the left-right direction is set so that substantially equal loads act on the left and right crawler traveling devices when the grain storage unit is fully loaded with grains at the moving position.

[Operation] According to the structure of claim 1, the traveling portion including the crawler traveling device and the operating portion, and the working portion including the threshing portion and the grain accommodating portion are provided in the left-right direction of the machine body. Since the relative movement can be adjusted, if the grain storage section becomes heavy and the left-right balance changes, it is possible to move the traveling section and the working section relatively laterally to absorb the change in the balance. The left-right balance can be maintained in a predetermined state even if the amount of grains is different.

Since the driving unit is integral with the traveling unit, the positional relationship between the driving unit and the crawlers does not change regardless of the lateral movement of the working unit. For example, when the operating unit is integrated with the working unit, the grain storage amount in the Glen tank increases during work traveling, and when the working unit moves to the left, the operating unit also moves to the left and May cause the illusion that the aircraft has shifted laterally from the line, but in the case of this application, the line of sight does not change even if the working part moves laterally, so it is possible to maintain a constant feeling of control. It is easy to drive.

When the harvesting threshing work is performed to increase the amount of collected grain in the grain container, the heavier grain container moves in the direction toward the lateral center of the machine body. The relative movement mechanism functions to correct the loss of left-right balance of the aircraft. Therefore, it becomes easy to drive.

Particularly, according to the structure of claim 1, the grain storage
The side plates on the left and right outer sides of the body can be laterally bulged and displaced
However , when the working unit is at the most moved position in the left-right direction, the side plates on the left and right sides of the body of the grain container are moved to the working unit.
The overhang amount of allowed out Zhang laterally outward opposite to the direction the lateral direction from the run of the grain receiving portion, so like made properly in overhanging amount from the running portion of the grain receiving portion in the standard position West
Therefore , while improving the left-right balance when the grain storage section is fully filled with grains, the grain storage section is greatly expanded outward from the running section even when the left and right end positions of the body of the grain storage section are in the standard position. It is possible to move the grain storage unit to the lateral outside without overhanging, and it is possible to increase the storage amount for that amount without increasing the overhanging amount from the traveling unit.

According to the structure of claim 2, since the mowing section and the engine are arranged in the traveling section, it is necessary to provide a laterally movable structure in the transmission system between the engine, the mowing section and the crawler traveling device. There is no such thing, and you can use simple things as before.

According to the third aspect of the present invention, when the grains are fully loaded in the grain accommodating portion, the relative movement amount of the working portion at the movement position is set so that the left and right crawlers have substantially equal loads. Therefore, when the total weight of the aircraft becomes the heaviest, the left-right balance is in the optimum state. This is because the left and right balances are optimally set when the grain container is empty before the work is started, and the left and right balances are not balanced when the grain is fully loaded at the moving position. The absolute value of the load difference between the left and right crawlers at the time of collapse can be reduced, which reduces the difficulty of maneuvering and facilitates driving.

[Effect] With the combine according to any one of claims 1 to 3, (a)
By moving the running part and the working part relative to each other in a state where the driving part is integrated with the crawler running device, it is possible to maintain a constant relationship between the driving part and the running part, and to make it easy to control while working. It has been possible to provide a vehicle body moving device that can correct the left-right balance that changes in accordance with the above and improve traveling performance. (B) It becomes possible to correct the imbalance of the left-right balance due to the collection of the grains in the grain accommodating section, and the left-right balance can be maintained in a good state, which facilitates the operation. It is also possible to correct the balance according to the degree of collapse. (C) In particular, while correcting the loss of left-right balance due to grain collection, it does not increase the amount of overhang from the running part regardless of whether the working part is in the standard position or the moving position. There is an advantage that the amount of collected grains can be increased.

In the vehicle body moving device according to the second aspect of the present invention, since the mowing section and the engine are arranged in the traveling section, the transmission system to the mowing section and the traveling transmission system do not become complicated, and the transmission to the mowing section is prevented. There is an advantage that the above-mentioned effects (a) to (c) can be obtained while the system and the traveling transmission system have the conventional structure.

In the vehicle body moving device according to the third aspect of the present invention, the maneuverability can be further improved by optimizing the left-right balance when the weight of the machine body becomes heaviest.
