装置に関する。BACKGROUND OF THE INVENTION The present invention is tuned so that the driving speed of the reaper and the feed chain increases as the traveling speed increases, and the driving speed of the reaper and the feed chain decreases as the traveling speed decreases. The present invention relates to a combine threshing control device.

Description of the Related Art In a combine of this type, the driving speed of a cutting unit and a feed chain is adjusted in accordance with the traveling speed at the time of cutting, so that a conveyance jam at the cutting unit or a rod from the cutting unit to the feed chain is performed. The aim is to improve the threshing efficiency by making the delivery smooth.

て、脱穀負荷の変動を少なくできる。In addition, since the driving speed of the cutting unit and the drive speed of the feed chain are coordinated and linked to the traveling speed at the time of cutting, that is, the drive speed of the feed chain is automatically adjusted in accordance with the amount of cut culm. For example, compared to the case where the feed chain is driven at a constant speed irrespective of the change in the amount of cut culm, the thickness of the layer of the transported culm group by the feed chain is constant regardless of the change in the amount of cut culm. As a result, fluctuations in threshing load can be reduced.

する等の現象の生じることがあった。By the way, in the threshing apparatus, in general, in order to improve the threshing efficiency, the threshing is handled at as high a speed as possible so that the threshing can be performed even at a high running speed at which the drive speed of the feed chain is high. The rotation speed of the torso is set. As a result, at a low traveling speed, the driving speed of the feed chain is also slow, and the time for the rods to stay in the handling room is prolonged, resulting in excessive threshing. And threshing load increases,
In some cases, phenomena such as an increase in the amount of foreign matter mixed in the grain, which is a product, and deterioration in sorting performance may occur.

る。SUMMARY OF THE INVENTION The present invention is characterized in that a cutting section for cutting and transporting planted cereal rods, and a feed chain for clamping and transporting the roots of the cereal rods sent from the cutting section to the rear. And a threshing device for threshing the transport gantry transported by the feed chain, and adjusting the drive speed of each of the cutting unit and the feed chain in synchronization with an increase or decrease in the drive speed of a traveling device. A threshing control device for a combine provided with a driving means, wherein a dust-feeding valve, which is capable of changing a mounting angle with respect to a radial direction of a handling cylinder, is pivotally attached to a top plate of a handling room in the threshing device, The speed at which the processing object in the handling room moves in the axial direction of the handling cylinder can be adjusted by adjusting the feeding angle, and when the drive speed of the feed chain increases, the mounting angle decreases, and There the attachment angle and the driving speed becomes late Dochen in that is provided with a linkage mechanism to large.

れてしまうことを抑制できる。According to the above-mentioned feature, when the driving speed of the feed chain is reduced, the attachment angle of the dust feed valve is increased by the operation of the linking mechanism. Regardless of the speed,
It is quickly discharged from the dust outlet at the rear of the handling room, which prevents excess threshing and an increase in threshing load caused by the material to be discharged staying in the handling room more than necessary. When the driving speed of the chain increases, the attachment angle of the dust valve becomes smaller due to the function of the linkage mechanism. Premature discharge from the room can be suppressed.

The threshing control of the combine with improved performance was realized by suppressing the increase in threshing load during low-speed running and the adverse effect on the sorting performance, while maintaining the state of rotating and improving the threshing efficiency.
