Description

DETAILED DESCRIPTION OF THE INVENTION The field of industrial application relates to a rolling device for a combine harvester.

2. Description of the Related Art] The left and right inclination of a harvester is detected, and the reaping device is controlled to roll toward the opposite side of the inclination relative to the vehicle body to maintain it in a horizontal position.

Problems to be Solved by the Invention In cutting and harvesting work using a combine harvester, there are many reaping methods in which one side of the combine harvester is always positioned on the uncut culm side and the harvest is proceeded without moving. In this type of work, the traveling device is installed to cover the full width of the cutting by the reaping device, so if the traveling device on the uncut culm side sinks below the soil surface and slopes, this traveling device will roll up mud and separate it. The grass body jumps up onto the separated grain culms, interfering with harvesting.

Means for Solving the Problems This invention relates to the reaping operation of a combine harvester in which a front reaping device (4) is controlled to roll left and right with respect to a vehicle body (3) having a pair of left and right running devices (1) and (2). In the rolling deviation interval between the outer end of the traveling device (1), which sometimes runs mainly near the uncut culm side, and the weeding body (5) at the lateral end of the reaping device (4) facing the front. , the deviation interval (A) at the time of maximum rolling on the uncut culm side in which the traveling device (1) is deflected outward in rolling toward the uncut culm side, and the traveling device (1) in rolling to the opposite side. 1
) is set to be approximately the same as or larger than the deflection interval CB) at the time of maximum rolling on the cut culm side which is deflected inward.

Effect of the Invention The pair of left and right traveling devices (1) and (2) are driven to run, and while the front reaping device (4) is reaping the culm to be guided inside the cutting body (5), the rear threshing device section is Changes in the weight of the combine harvester during the transport and dehulling operation,
Or the running equipment may be damaged due to irregularities or changes in hardness or softness of the running soil surface!
When (1) and (2) are tilted to the negative side, the entire combine harvester is tilted in the same direction, causing the reaping device (4) to tilt from side to side, making the cutting height uneven on the left and right sides. Due to this horizontal inclination, the reaping device (4) is controlled to roll toward the opposite side of the inclination with respect to the vehicle body (3), and the reaping device (4) is controlled to roll in the opposite direction to the inclination of the vehicle body (3). Control is maintained in a horizontal position parallel to the surface of the harvested soil.

In the rolling control of such a reaping device (4),

5) is located at a position deviated outward from the outer end of the traveling device (1) and performs a weeding action. The amount of deviation at the time of maximum rolling on the uncut culm side at this time, that is, the distance in the left-right direction between the outer end of the traveling device (1) and the weeding body (5) at this time is defined as the deviation interval (A). On the other hand, if the cutting device (4) rolls due to the traveling device (2) on the cut culm side sinking significantly and the combine tilting, it will separate into the inside of the traveling device 2i (1) on the uncut culm side. The grass body (5) is deviated, and at this time, the grass body (5) is maintained so that it does not intrude into the adjacent uncut culm.

The amount of deviation at maximum rolling on the cut culm side at this time, that is,
At this time, the weeding body (5) deviates inward of the traveling device (1).
